TI Upregulation of Cannabinoid Type 1 Receptors in Dopamine D2 Receptor

AB Background:
The anatomical proximity of the cannabinoid type 1 (CNR1/CB1R) and the dopamine D2 receptors (DRD2), their ability to form CB1R-DRD2 heteromers, their opposing roles in locomotion, and their involvement in ethanol's reinforcing and addictive properties prompted us to study the levels and distribution of CB1R after chronic ethanol intake, in the presence and absence of DRD2.
Methods:
We monitored the drinking patterns and locomotor activity of Drd2+/+ and Drd2-/- mice consuming either water or a 20% (v/v) ethanol solution (forced ethanol intake) for 6 months and used the selective CB1 receptor antagonist [3H]SR141716A to quantify CB1R levels in different brain regions with in vitro receptor autoradiography.
Results:
We found that the lack of DRD2 leads to a marked upregulation (approximately 2-fold increase) of CB1R in the cerebral cortex, the caudate-putamen, and the nucleus accumbens, which was reversed by chronic ethanol intake.
Conclusions:
The results suggest that DRD2-mediated dopaminergic neurotransmission and chronic ethanol intake exert an inhibitory effect on cannabinoid receptor expression in cortical and striatal regions implicated in the reinforcing and addictive properties of ethanol.

AB P>Background
Silymarin is the most commonly used herbal product for chronic liver disease; yet, whether silymarin protects against liver disease progression remains unclear.
Aim
To assess the effects of silymarin use on subsequent liver disease progression in 1049 patients of the Hepatitis C Antiviral Long-Term Treatment against Cirrhosis (HALT-C) trial who had advanced fibrosis or cirrhosis and had failed prior peginterferon plus ribavirin treatment.
Methods
Patients recorded their use of silymarin at baseline and were followed up for liver disease progression (two point increase in Ishak fibrosis score across baseline, year 1.5, and year 3.5 biopsies) and over 8.65 years for clinical outcomes.
Results
At baseline, 34% of patients had used silymarin, half of whom were current users. Use of silymarin was associated (P < 0.05) with male gender; oesophageal varices; higher ALT and albumin; and lower AST/ALT ratio, among other features. Baseline users had less hepatic collagen content on study biopsies and had less histological progression (HR: 0.57, 95% CI: 0.33-1.00; P-trend for longer duration of use=0.026). No effect was seen for clinical outcomes.
Conclusions
Silymarin use among patients with advanced hepatitis C-related liver disease is associated with reduced progression from fibrosis to cirrhosis, but has no impact on clinical outcomes (Clinicaltrials.gov #NCT00006164).

AB Varicella-zoster virus (VZV) encodes three immediate-early proteins, IE4, IE62, and IE63; however, only IE62 has TAATGARAT-like sequences in its promoter which are present in the promoters of each of the herpes simplex virus immediate-early proteins. The TAATGARAT-like elements on the IE62 promoter bind to VZV ORF10 protein, Oct1, and HCF-1. In addition, histone methyltransferases are recruited to the IE62 promoter to modify chromatin to a transcriptionally active form. VZV IE62, the major VZV transactivator binds to VZV IE4 and IE63, and Med25, part of the mediator complex which upregulates gene expression. VZV IE62, IE4, and IE63 are present in the viral tegument where they may help to regulate transcription early in infection. IE63 binds to several cellular proteins including ASF1 and RNA polymerase II.
Two hypotheses have been proposed for regulation of VZV gene expression during latency. First, relocalization of HCF-1 from the cytoplasm to the nucleus of sensory ganglia in response to stimuli associated with reactivation may help to augment transcription of IE62 to reactivate VZV from latency. Second, promoters of latent genes are maintained in a euchromatic state allowing their transcription, while promoters of genes not associated with latency are in a heterochromatic state resulting in repression of transcription.

AB In October 2010, a group of experts met as part of the transatlantic think tank for toxicology (t(4)) to exchange ideas about the current status and future of safety testing of nanomaterials. At present, there is no widely accepted path forward to assure appropriate and effective hazard identification for engineered nanomaterials. The group discussed needs for characterization of nanomaterials and identified testing protocols that incorporate the use of innovative alternative whole models such as zebrafish or C. elegans, as well as in vitro or alternative methods to examine specific functional pathways and modes of action. The group proposed elements of a potential testing scheme for nanomaterials that works towards an integrated testing strategy, incorporating the goals of the NRC report Toxicity Testing in the 21(st) Century: A Vision and a Strategy by focusing on pathways of toxic response, and utilizing an evidence-based strategy for developing the knowledge base for safety assessment. Finally, the group recommended that a reliable, open, curated database be developed that interfaces with existing databases to enable sharing of information.

AB The growing societal and individual burden of dementia means that counting the cases of dementia is critical. There are several approaches and methods that can be used to identify dementia cases. The ascertainment can range from very detailed characterization of the individual (deep) to a brief standardized assessment (wide) that emphasizes individual functioning. The choice of going deep or wide depends on the goal of the ascertainment. These goals are discussed, as well as the emerging issues that may change the way dementia cases are classified.

AB This article focuses on the effects of operational differences in case ascertainment on estimates of prevalence and incidence of cognitive impairment and/or dementia of the Alzheimer type. Experience and insights are discussed by investigators from the Framingham Heart Study, the East Boston Senior Health Project, the Chicago Health and Aging Project, the Mayo Clinic Study of Aging, the Baltimore Longitudinal Study of Aging, and the Aging, Demographics, and Memory Study. There is a general consensus that the single most important factor determining prevalence estimates of Alzheimer's disease (AD) is the severity of cognitive impairment used as a threshold to define cases. Studies that require a level of cognitive impairment in which persons are unable to provide self-care will have much lower estimates than the studies aimed at identifying persons in the earliest stages of AD. There are limited autopsy data from the aforementioned epidemiological studies to address accuracy in the diagnosis of etiological subtype, namely the specification of AD alone or in combination with other types of pathology. However, other community-based cohort studies show that many persons with mild cognitive impairment and also some persons without dementia or mild cognitive impairment meet pathological criteria for AD, thereby suggesting that the number of persons who would benefit from an effective secondary prevention intervention is probably higher than the published prevalence estimates. Improved accuracy in the clinical diagnosis of AD is anticipated with the addition of molecular and structural biomarkers in the next generation of epidemiological studies.

TI Loss of short-term symptomatic benefit in patients with an occluded

AB Background The OAT found that routine late (3-28 days post-myocardial infarction) percutaneous coronary intervention (PCI) of an occluded infarct-related artery did not reduce death, reinfarction, or heart failure relative to medical treatment (MED). Angina rates were lower in PCI early, but the advantage over MED was lost by 3 years.
Methods Angina and revascularization status were collected at 4 months, then annually. We assessed whether non-protocol revascularization procedures in MED accounted for loss of the early symptomatic advantage of PCI.
Results Seven per 100 more PCI patients were angina-free at 4 months (P < .001) and 5 per 100 at 12 months (P = .005) with the difference narrowing to 1 per 100 at 3 years (P = .34). Non-protocol revascularization was more frequent in MED (5-year rate 22% vs 19% PCI, P = .05). Indications for revascularization included acute coronary syndromes (39% PCI vs 38% MED), stable angina/inducible ischemia (39% in each group), and physician preference (17% PCI vs 15% MED). Revascularization rates among patients with angina at any time during follow-up (35% of cohort) did not differ by treatment group (5-year rates 26% PCI vs 28% MED). Most symptomatic patients were treated without revascularization during follow-up (77%).
Conclusions In a large randomized clinical trial of stable post-myocardial infarction patients, the modest benefit on angina from PCI of an occluded infarct-related artery was lost by 3 years. Revascularization was slightly more common in MED during follow-up but was not driven by acute ischemia, and almost 1 in 5 procedures were attributed to physician preference alone.

AB Background Wyman W. Lai, MD, MPH, and Victoria L. Vetter, MD, MPH.
The Pediatric Heart Network (PHN), funded under the U. S. National Institutes of Health-National Heart, Lung, and Blood Institute (NIH-NHLBI), includes two Clinical Research Skills Development (CRSD) Cores, which were awarded to The Children's Hospital of Philadelphia and to the Morgan Stanley Children's Hospital of New York-Presbyterian. To provide information on how to develop a clinical research career to a larger number of potential young investigators in pediatric cardiology, the directors of these two CRSD Cores jointly organized a one-day seminar for fellows and junior faculty from all of the PHN Core sites. The participants included faculty members from the PHN and the NHLBI. The day-long seminar was held on April 29, 2009, at the NHLBI site, immediately preceding the PHN Steering Committee meeting in Bethesda, MD.
Methods The goals of the seminar were 1) to provide fellows and early investigators with basic skills in clinical research 2) to provide a forum for discussion of important research career choices 3) to introduce attendees to each other and to established clinical researchers in pediatric cardiology, and 4) to publish a commentary on the future of clinical research in pediatric cardiology.
Results The following chapters are compilations of the talks given at the 2009 PHN Clinical Research Skills Development Seminar, published to share the information provided with a broader audience of those interested in learning how to develop a clinical research career in pediatric cardiology. The discussions of types of clinical research, research skills, career development strategies, funding, and career management are applicable to research careers in other areas of clinical medicine as well.
Conclusions The aim of this compilation is to stimulate those who might be interested in the research career options available to investigators. (Am Heart J 2011;161:13-67.)

AB If definitive evidence concerning treatment effectiveness becomes available from an ongoing randomized clinical trial, then the trial could be stopped early, with the public release of results benefiting current and future patients. However, stopping an ongoing trial based on accruing outcome data requires methodological rigor to preserve validity of the trial conclusions. This has led to the use of formal interim monitoring procedures, which include inefficacy monitoring that will stop a trial early when the experimental treatment appears not to be working. For participants, inefficacy monitoring is especially important as it ensures that they are not being treated worse than if they had not enrolled on the trial. We discuss the importance of reporting with trial results the formal interim inefficacy monitoring guidelines that were utilized, and, if none were used, the reasons for their absence. A survey of two leading medical journals suggests that this is not current practice.

ID MULTIPLE AUTHORSHIP; MEDICAL JOURNALS; TRENDS; PATTERNS; ARTICLE
AB Multiple authorship is becoming increasingly common in bioethics research. There are well-established criteria for authorship in empirical bioethics research but not for conceptual research. It is important to develop criteria for authorship in conceptual publications to prevent undeserved authorship and uphold standards of fairness and accountability. This article explores the issue of multiple authorship in bioethics and develops criteria for determining who should be an author on a conceptual publication in bioethics. Authorship in conceptual research should be based on contributing substantially to: (1) identifying a topic, problem, or issue to study; (2) reviewing and interpreting the relevant literature; (3) formulating, analyzing, and evaluating arguments that support one or more theses; (4) responding to objections and counterarguments; and (5) drafting the manuscript and approving the final version. Authors of conceptual publications should participate substantially in at least two of areas (1)-(5).

TI Genomic profiling of genes contributing to metastasis in a mouse model
of thyroid follicular carcinoma
SO AMERICAN JOURNAL OF CANCER RESEARCH
LA English
DT Article
DE Metastasis; thyroid cancer; mouse model; microarray; gene expression
AB Metastasis is the major cause of thyroid cancer-related death. However, little is known about the genes involved in the metastatic spread of thyroid carcinomas. We have created a mouse that spontaneously develops metastatic follicular thyroid carcinoma (FTC). This mouse harbors a targeted mutation (denoted TR beta PV) in the thyroid hormone receptor beta gene (Thrb(PV/PV) mice). Our recent studies show that the highly elevated level of thyroid stimulating hormone (TSH) in Thrb(PV/PV) mice promotes proliferation of thyroid tumor cells, but requires the collaboration of the oncogenic action of TR beta PV to empower the tumor cells to undergo distant metastasis. To uncover genes destined to drive the metastatic process, we used cDNA microarrays to compare the genomic expression profile of laser capture microdissected thyroid tumor lesions of Thrb(PV/PV) mice with that of hyperplastic thyroid cells of wild-type mice having elevated TSH induced by treatment with the anti-thyroid drug propylthiouracil (WT-PTU mice). Analyses of microarray data indicated that the expressions of 150 genes were significantly altered between Thrb(PV/PV) and WT-PTU mice (87 genes had higher expression and 63 genes had lower expression in Thrb(PV/PV) mice than in WT-PTU mice). Thirty-six percent of genes with altered expression function as key regulators in metastasis. The remaining genes were involved in various cellular processes including metabolism, intracellular trafficking, transcriptional regulation, post-transcriptional modification, and cell-cell/extracellular matrix signaling. The present studies have uncovered novel genes responsible for the metastatic spread of FTC and, furthermore, have shown that the metastatic process of thyroid cancer requires effective collaboration among genes with diverse cellular functions. Importantly, the present studies indicate that the tumor cells in the primary lesions are endowed with the genes destined to promote metastasis. Thus, our study has provided new insights into the understanding of the metastatic spread of human thyroid cancer.

TI Decrease in CD8+lymphocyte number and altered cytokine profile in human
prostate cancer
SO AMERICAN JOURNAL OF CANCER RESEARCH
LA English
DT Article
DE Prostate cancer; lymphocytes; cytokines; histomathematics;
histopathology
AB The tumor microenvironment is comprised of multiple cell types arranged in a three-dimensional structure. Interactions amongst the various cell components play an important role in neoplasia, including the inflammatory reaction that occurs as part of the host response. In this study, the regional lymphocyte subpopulations and cytokine profiles associated with prostate cancer were examined using a quantitative imaging approach and expression microarray analysis. Lymphocytes were measured in four different epithelial phenotypes in prostate cancer specimens: carcinoma; prostatic intraepithelial neoplasia (PIN); benign prostate hyperplasia (BPH); and normal epithelium. The data indicate that CD8 positive, cytotoxic T lymphocytes are significantly decreased in regions adjacent to hyperplasia and carcinoma as compared to normal epithelium and PIN. In contrast the relative number of CD4 positive and CD20 positive lymphocytes did not change markedly. Parallel mRNA expression array analysis of the normal and tumor microenvironments identified a distinct cytokine profile in cancer, with 24 dysregulated genes in tumor epithelium and nine altered in tumor-associated stroma. Overall, these data indicate that the spatial distribution of CD8 positive, cytotoxic T lymphocytes is dysregulated in human prostate glands that contain cancer, and cytokine profiles are altered at the mRNA level.

TI Global expression profiling reveals gain-of-function oncogenic activity
of a mutated thyroid hormone receptor in thyroid carcinogenesis
SO AMERICAN JOURNAL OF CANCER RESEARCH
LA English
DT Article
DE Mutant TR; thyroid cancer; mouse model; microarray; gene expression
AB Thyroid hormone receptors (TRs) are critical in regulating gene expression in normal physiological processes. Decreased expression and/or somatic mutations of TRs have been shown to be associated several types of human cancers including liver, breast, lung, and thyroid. To understand the molecular mechanisms by which mutated TRs promote carcinogenesis, an animal model of follicular thyroid carcinoma (FTC) (Thrb(PV/PV) mice) was used in the present study. The Thrb(PV/PV) mouse harbors a knockin dominant negative PV mutation, identified in a patient with resistance to thyroid hormone. To understand whether oncogenic actions of PV involve not only the loss of normal TR functions but also gain-of-function activities, we compared the gene expression profiles of thyroid lesions in Thrb(PV/PV) mice and Thra1(-/-)Thrb(-/-) mice that also spontaneously develop FTC, but with less severe malignancy. Analysis of the cDNA microarray data derived from microdissected thyroid tumor cells of these two mice showed contrasting global gene expression profiles. With stringent selection using 2.5- fold change (p<0.01) in cDNA microarray analysis, 241 genes with altered gene expression were identified. Nearly half of the genes (n=103: 42.7% of total) with altered gene expression in thyroid tumor cells of Thrb(PV/PV) mice were associated with tumorigenesis and metastasis; some of these genes function as oncogenes in human thyroid cancers. The remaining genes were found to function in transcriptional regulation, RNA processing, cell proliferation, apoptosis, angiogenesis, and cytoskeleton modification. These results indicate that the more aggressive thyroid tumor progression in Thrb(PV/PV) mice was not due simply to the loss of tumor suppressor functions of TR via mutation but also, importantly, to gain-of-function in the oncogenic activities of PV to drive thyroid carcinogenesis. Thus, the present study identifies a novel mechanism by which a mutated TR beta evolves with an oncogenic advantage to promote thyroid carcinogenesis.

carcinoma (ESCC); non-small cell lung cancer (NSCLC); epidemiology; risk
factors; molecular characteristics; prognostic markers; targeted therapy
AB Squamous cell carcinoma (SCC) is an epithelial malignancy involving many anatomical sites and is the most common cancer capable of metastatic spread. Development of early diagnosis methods and novel therapeutics are important for prevention and mortality reduction. In this effort, numerous molecular alterations have been described in SCCs. SCCs share many phenotypic and molecular characteristics, but they have not been extensively compared. This article reviews SCC as a disease, including: epidemiology, pathology, risk factors, molecular characteristics, prognostic markers, targeted therapy, and a new approach to studying SCCs. Through this comparison, several themes are apparent. For example, HPV infection is a common risk factor among the four major SCCs (NMSC, HNSC, ESCC, and NSCLC) and molecular abnormalities in cell-cycle regulation and signal transduction predominate. These data reveal that the molecular insights, new markers, and drug targets discovered in individual SCCs may shed light on this type of cancer as a whole.

AB Previous studies have identified several dysregulated microRNAs in esophageal squamous cell carcinoma (ESCC); however, to date there are no ex vivo analyses comparing expression levels of these regulatory molecules in esophageal squamous cell tumors versus patient-matched normal epithelium. We describe here a technical strategy to evaluate microRNAs in normal esophageal basal cells (NB), normal esophageal differentiated cells (ND), and tumor cells (T). Laser capture microdissection was used to procure target populations from five cases and 18 ESCC-associated microRNAs were measured by RT-qPCR. Five microRNAs (miR-25, miR-106b, miR-21, miR-203, and miR-145) demonstrated consistent differential expression in at least one of the three comparisons: T vs. NB, T vs. ND, or NB vs. ND. The potential regulatory role of the microRNAs in ESCC was further evaluated by correlating their expression with a matched mRNA dataset, which included the same five cases and cell populations. In conclusion, the present work demonstrates the feasibility of studying microRNA levels in precisely dissected cell populations from clinical samples, and sheds light on the molecular mechanisms associated with ESCC.

AB Ginseng is one of the most popular herbal supplements on the US market. Numerous reports of adverse effects from products containing ginseng have been filed with the US Food and Drug Administration (FDA) and the literature documents a "ginseng abuse syndrome" among regular users. However, the chronic toxic effects of ginseng are not well characterized. Because of its significant human exposure and the fact that little information on its toxicity is available, Panax ginseng was nominated by the US National Institutes of Health (NIH) to the US National Toxicology Program (NTP) to assess its carcinogenic potential. In this paper, we reported the results of NTP chronic toxicity and tumorigenicity bioassay. It shows that, under these experimental conditions, Panax ginseng is not toxic or tumorigenic.

AB Cutaneous mastocytosis in children is a generally benign disease that can present at birth and is often associated with mast cell mediator-related symptoms including pruritus, flushing, and abdominal pain with diarrhea. The most common form of presentation is urticaria pigmentosa, also referred to as maculopapular mastocytosis. Flares of lesions are induced by triggers such as physical stimuli, changes in temperature, anxiety, medications, and exercise. The skin lesions are typically present on the extremities. Symptoms respond to topical and systemic anti-mediator therapy including antihistamines and cromolyn sodium. Remission at puberty is seen in a majority of cases. Progression to systemic mastocytosis with involvement of extracutaneous organs is not common.
The cause of cutaneous mastocytosis is unknown and familial cases are rare. Mutations of c-kit have been observed in the skin of those affected. The diagnosis is established on clinical grounds and the findings on skin biopsy. Bone marrow studies are recommended if there is suspicion of progression of disease to an adult form, if cytoreductive therapy is contemplated, or if skin lesions remain present and/or tryptase levels remain elevated after puberty. The use of chemotherapy, including kinase inhibitors, is strongly discouraged unless severe hematologic disease is present, since malignant evolution is extremely rare.

EXPENDITURE; GROWTH; YOUNG
AB Background: Isolated methylmalonic acidemia (MMA) is managed by dietary protein restriction and medical food supplementation. Resting energy expenditure (REE) can be depressed in affected individuals for undefined reasons.
Objective: The objective was to document the spectrum of nutritional approaches used to treat patients with MMA, measure REE, and analyze the dependence of REE on body composition, biochemical, and nutritional variables.
Design: Twenty-nine patients with isolated MMA (22 mut, 5 cblA, 2 cblB; 15 males, 14 females; age range: 2-35 y) underwent evaluation. REE was measured with open-circuit calorimetry and compared with predicted values by using age-appropriate equations.
Results: Nutritional regimens were as follows: protein restriction with medical food (n = 17 of 29), protein restriction with medical food and supplemental isoleucine or valine (n = 5 of 29), or the use of natural protein alone for dietary needs (n = 7 of 29). Most mut patients had short stature and higher percentage fat mass compared with reference controls. Measured REE decreased to 74 +/- 13.6% of predicted (P<0.001) in the <= 18-y group (n = 22) and to 83 +/- 11.1% (P = 0.004) in patients aged >18 y (n = 7). Linear regression modeling suggested that age (P = 0.001), creatinine clearance (P = 0.01), and height z score (P = 0.04) accounted for part of the variance of measured REE per kilogram of fat-free mass (model R-2 = 0.66, P<0.0001).
Conclusions: There is wide variation in the dietary treatment of MMA. Standard predictive equations overestimate REE in this population primarily due to their altered body composition and decreased renal function. Defining actual energy needs will help optimize nutrition and protect individuals from overfeeding. This trial is registered at clinicaltrials.gov as NCT00078078. Am J Clin Nutr 2011;93:47-56.

AB Background: Mixed results have been reported in recent epidemiologic studies in Western populations that have investigated the hypothesis that high glycemic load may increase the risk of colorectal cancer. This association has not been prospectively evaluated in other populations.
Objective: We examined the association of overall glycemic index and glycemic load with colorectal cancer risk in a prospective cohort of Chinese women.
Design: A total of 73,061 women aged 40-70 y and free of cancer at enrollment were included in this analysis. Usual dietary intake was assessed at baseline (1997-2000) and reassessed during the first follow-up (2000-2002) through in-person interviews by using a validated food-frequency questionnaire.
Results: During an average follow-up of 9.1 y, 475 incident colorectal cancer cases were identified. Glycemic load was not associated with colorectal cancer risk (P for trend = 0.84). The multivariable hazard ratio for the highest compared with the lowest quintile of glycemic load was 0.94 (95% CI: 0.71, 1.24). Similar results were also observed for associations with dietary glycemic index and total carbohydrate intake, and results did not vary by excluding individuals with a history of diabetes from the analysis.
Conclusion: This prospective study, conducted in a population with a high intake of carbohydrates, provides no evidence that a high-glycemic index diet or high glycemic load is associated with an increased risk of colorectal cancer. Am J Clin Nutr 2011;93:101-7.

AB The cellular composition of the tumor microenvironment may affect survival in diffuse large B-cell lymphoma (DLBCL). We performed immunostains for 2 stromal cell markers, CD68 and SPARC (secreted protein, acidic and rich in cysteine), in 262 patients with DLBCL treated with rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapies. Patients with any SPARC+ cells in the microenvironment had a significantly longer overall survival, and patients with high SPARC positivity in the microenvironment also had a significantly longer event free survival. Survival differences were mainly due to the prognostic effect of SPARC+ cells in activated B-cell (ABC)-type DLBCL, with no effect found in the germinal center B-cell type DLBCL. Of clinical features examined, only the number of extranodal sites was significantly associated with SPARC expression. Multivariate analysis revealed that SPARC expression predicted patient survival independent of the International Prognostic Index or tumor cell of origin. SPARC expression in the microenvironment of DLBCL can be used for prognostic purposes, determining a subgroup of patients with ABC DLBCL who have significantly longer survival. More aggressive chemotherapy protocols should be considered for patients with ABC DLBCL without SPARC+ stromal cells. CD68 expression by cells in the microenvironment did not predict survival.

AB In studies of weight and mortality, the construct of reverse causation has come to be used to imply that the exposure-outcome relation is biased by weight loss due to preexisting illness. Observed weight-mortality associations are sometimes thought to result from this bias. Evidence for the occurrence of such bias is weak and inconsistent, suggesting that either the analytical methods used have been inadequate or else illness-related weight loss is not an important source of bias. Deleting participants has been the most frequent approach to control possible bias. As implemented, this can lead to deletion of almost 90% of all deaths in a sample and to deletion of more overweight and obese participants than participants with normal or below normal weight. Because it has not been demonstrated that the procedures used to adjust for reverse causation increase validity or have large or systematic effects on relative risks, it is premature to consider reverse causation as an important cause of bias. Further research would be useful to elucidate the potential effects and importance of reverse causation or illness-related weight loss as a source of bias in the observed associations between weight and mortality in cohort studies.

AB Removal or impairment of ovaries before menopause may affect a woman's breast cancer risk by altering her cumulative exposure to ovarian hormones. The Women's Contraceptive and Reproductive Experiences Study, a population-based, multicenter case-control study of incident invasive breast cancer, recruited women aged 35-64 years (4,490 cases and 4,611 controls) who provided data on ovariectomy, hysterectomy, and tubal sterilization during in-person interviews. Controls were frequency-matched to cases by age, race, and study site. Unconditional logistic regression analysis was used. Women who had not undergone premenopausal reproductive surgery were the referent group. Bilateral ovariectomy was associated with reduced breast cancer risk overall (odds ratio (OR) = 0.59, 95% confidence interval (CI): 0.50, 0.69) and among women < 45 years of age (ORs ranged from 0.31 to 0.52), but not among those who were older at surgery. It was also associated with a reduced risk for estrogen and progesterone receptor-positive tumors (OR = 0.63, 95% CI: 0.52, 0.75) but not receptor-negative tumors. Hysterectomy with ovarian conservation (OR = 0.83, 95% CI: 0.72, 0.96) and hysterectomy with partial ovary removal (OR = 0.73, 95% CI: 0.59, 0.91) were also associated with lower risk. No association with breast cancer risk was observed with tubal sterilization only or partial ovariectomy without hysterectomy. Reproductive organ surgeries may alter ovarian hormone levels, thereby affecting breast cancer risk.

AB Comparing agricultural cohorts with the general population is challenging because the general healthiness of farmers may mask potential adverse health effects of farming. Using data from the Agricultural Health Study, a cohort of 89,656 pesticide applicators and their spouses (N = 89, 656) in North Carolina and Iowa, the authors computed standardized mortality ratios (SMRs) comparing deaths from time of the enrollment (1993-1997) through 2007 to state-specific rates. To compensate for the cohort's overall healthiness, relative SMRs were estimated by calculating the SMR for each cause relative to the SMR for all other causes. In 1,198,129 person-years of follow-up, 6,419 deaths were observed. The all-cause mortality rate was less than expected (SMRapplicators = 0.54, 95% confidence interval (CI): 0.52, 0.55; SMRspouses = 0.52, 95% CI: 0.50, 0.55). SMRs for all cancers, heart disease, and diabetes were significantly below 1.0. In contrast, applicators experienced elevated numbers of machine-related deaths (SMR = 4.15, 95% CI: 3.18, 5.31), motor vehicle nontraffic accidents (SMR = 2.80, 95% CI: 1.81, 4.14), and collisions with objects (SMR = 2.12, 95% CI: 1.25, 3.34). In the relative SMR analysis for applicators, the relative mortality ratio was elevated for lymphohematopoietic cancers, melanoma, and digestive system, prostate, kidney, and brain cancers. Among spouses, relative SMRs exceeded 1.0 for lymphohematopoietic cancers and malignancies of the digestive system, brain, breast, and ovary. Unintentional fatal injuries remain an important risk for farmers; mortality ratios from several cancers were elevated relative to other causes.

AB Objective: To identify genetic variation influencing serum bilirubin levels in American Indians, we performed genome-wide screening and association analyses in the Strong Heart Family Study. Bilirubin is an endogenous antioxidant that has demonstrated an inverse relationship with cardiovascular disease. Genetic variation within the promoter region of uridine diphosphate glucuronosyltransferase (UGT1A1) on chromosome 2q has been associated with elevated serum bilirubin levels in European populations. However, no study has investigated the UGT1A1 promoter in American Indians.
Methods: Statistical analyses were carried out with 3,484 participants aged 14 to 93 years recruited from three geographic areas in the United States; Arizona, Oklahoma, and North and South Dakota.
Results: Variance components linkage analysis detected a quantitative trait locus (QTL) for bilirubin on chromosome 2q in the combined centers (LOD = 6.61, P = 4.24 x 10(-6)) and in Oklahoma (LOD = 5.65, P = 4.57 24 x 10(-5)). Genetic association of the UGT1A1 promoter polymorphism was significant for all geographic locations. After adjustment using conditional linkage for UGT1A1 promoter variance, the linkage signal dropped to 1.10 in the combined sample and to 3.32 (P = 0.02) in Oklahoma, indicating this polymorphism is not completely responsible for the linkage signal in American Indians. We also detected suggestive linkage signals in the Dakotas on chromosome 10p12 (LOD = 2.18) and in the combined centers (LOD = 2.24) on chromosome 10q21.
Conclusions: Replication of a serum bilirubin QTL on chromosome 2q in American Indians implicates UGT1A1 but further genotyping is warranted to identify additional causative polymorphisms. Evidence also supports a potential novel locus for bilirubin on chromosome 10. Am. J. Hum. Biol. 23: 118-125, 2011. (C) 2010 Wiley-Liss, Inc.

AB BACKGROUND
Central arterial stiffness is increasingly recognized as an important predictor of cardiovascular events and mortality in older adults; however, few studies have evaluated the association of arterial stiffness with mobility decline, a common consequence of vascular disease.
METHODS
We analyzed the association of pulse wave velocity (PWV), a measure of aortic stiffness, with longitudinal gait speed over 7 years in 2,172 participants in the Health, Aging and Body Composition (ABC) Study (mean age +/- s.d. 73.6 +/- 2.9 years, 48% men, 39% black).
RESULTS
In mixed-effects models adjusted for demographics, each s.d. (396 cm/s) higher PWV was associated with 0.015 (s.e. 0.004) m/s slower gait at baseline and throughout the study period in the full cohort (P < 0.001); this relationship was largely explained by hypertension and other vascular risk factors. Among participants with peripheral arterial disease (PAD) (n = 261; 12.7%), each s.d. higher PWV was independently associated with 0.028 (s.e. 0.010) m/s slower gait speed at baseline and throughout the study period (P < 0.01).
CONCLUSIONS
These findings suggest that aortic stiffness may be especially detrimental to mobility in older adults with already compromised arterial function.

AB Background: The annual mortality rate for maintenance hemodialysis patients in the United States is unacceptably high at 15%-20%. In 2004, we initiated the Frequent Hemodialysis Network (FHN) clinical trials. This report presents baseline characteristics of FHN Trial participants and compares them with hemodialysis patients tracked in US Renal Data System (USRDS) data.
Study Design: 2 separate randomized clinical trials.
Settings & Participants: FHN includes 332 patients with chronic kidney disease requiring long-term dialysis therapy enrolled in 2 separate randomized clinical trials. The FHN Daily Trial (245 randomly assigned participants) was designed to compare outcomes of 6-times-weekly in-center daily hemodialysis (1.5-2.75 h/session) with conventional 3-times-weekly in-center hemodialysis. The FHN Nocturnal Trial (87 randomly assigned participants) was designed to compare outcomes of 6-times-weekly home nocturnal (6-8 h/session) with conventional 3-times-weekly hemodialysis. USRDS data include 338,109 incident and prevalent long-term hemodialysis patients from the calendar year 2007.
Results: Participants in both trials were on average younger than the average hemodialysis patient in the United States (Daily Trial, 50.4 years; P < 0.001; Nocturnal Trial, 52.8 years; P < 0.001). Compared with USRDS data, whites were under-represented in the Daily Trial (36% vs 55%; P < 0.001), whereas Hispanics were under-represented in the Nocturnal Trial and over-represented in the Daily Trial (0% vs 28%; P < 0.001). In addition, there were more fistulas and fewer catheters in the Daily Trial (61% and 20%, respectively; P < 0.001 for both) and fewer grafts and more catheters in the Nocturnal Trial (10% and 44%, respectively; P < 0.005 for both).
Limitations: Clinical trial exclusion criteria and patient willingness to participate limit comparisons with the USRDS.
Conclusions: FHN participants were younger and the racial composition for each study was different from the racial composition of the aggregate US dialysis population. Catheters for vascular access were more common in FHN Nocturnal Trial participants. Am J Kidney Dis. 57(1): 90-100. (C) 2010 by the National Kidney Foundation, Inc. Published by Elsevier Inc.

AB Individual studies of the genetics of neural tube defects (NTDs) contain results on a small number of genes in each report. To identify genetic risk factors for NTDs, we evaluated potentially functional single nucleotide polymorphisms (SNPs) that are biologically plausible risk factors for NTDs but that have never been investigated for an association with NTDs, examined SNPs that previously showed no association with NTDs in published studies, and tried to confirmpreviously reported associations in folate-related and non-folate-related genes. We investigated 64 SNPs in 34 genes for association with spina bifida in up to 558 case families (520 cases, 507 mothers, 457 fathers) and 994 controls in Ireland. Case-control and mother-control comparisons of genotype frequencies, tests of transmission disequilibrium, and log-linear regression models were used to calculate effect estimates. Spina bifida was associated with over-transmission of the LEPR (leptin receptor) rs1805134 minor C allele [genotype relative risk (GRR): 1.5; 95% confidence interval (CI): 1.0-2.1; P=0.0264] and the COMT (catechol-O-methyltransferase) rs737865 major T allele (GRR: 1.4; 95% CI: 1.1-2.0; P=0.0206). After correcting for multiple comparisons, these individual test P-values exceeded 0.05. Consistent with previous reports, spina bifida was associated with MTHFR 677C> T, T (Brachyury) rs3127334, LEPR K109R, and PDGFRA promoter haplotype combinations. The associations between LEPR SNPs and spina bifida suggest a possible mechanism for the finding that obesity is a NTD risk factor. The association between a variant in COMT and spina bifida implicates methylation and epigenetics in NTDs. (C) 2010 Wiley-Liss, Inc.

AB Angelman syndrome (AS) is a neurodevelopmental disorder caused by a lack of expression of the maternal copy of UBE3A. Although the "classic" features of AS are well described, few large-scale studies have delineated the clinical features in AS. We present baseline data from 92 children with a molecular diagnosis of AS between 5 and 60 months old who are enrolled in the National Institutes of Health Rare Diseases Clinical Research Network Angelman Syndrome Natural History Study from January 2006 to March 2008. Seventy-four percent of participants had deletions, 14% had either uniparental disomy (UPD) or imprinting defects, and 12% had UBE3A mutations. Participants with UPD/imprinting defects were heavier (P=0.0002), while those with deletions were lighter, than the general population (P<0.0001). Twenty out of 92 participants were underweight, all of whom had deletions or UBE3A mutations. Eight out of 92 participants (6/13 (46%) with UPD/imprinting defects and 2/11 (18%) with UBE3A mutations) were obese. Seventy-four out of 92 participants (80%) had absolute or relative microcephaly. No participant was macrocephalic. The most common behavioral findings were mouthing behavior (95%), short attention span (92%), ataxic or broad-based gait (88%), history of sleep difficulties (80%), and fascination with water 75%). Frequent, easily provoked laughter was observed in 60%. Clinical seizures were reported in 65% of participants but all electroencephalograms (EEGs) were abnormal. We conclude that the most characteristic feature of AS is the neurobehavioral phenotype, but specific EEG findings are highly sensitive for AS. Obesity is common among those with UPD/imprinting defects. (C) 2010 Wiley-Liss, Inc.

AB The findings of a recent study associate LPHN3, a member of the latrophilin family, with an increased risk of developing attention deficit/hyperactivity disorder (ADHD), the most common psychiatric disorder in childhood and adolescence. Latrophilins comprise a new family of G protein-coupled receptors of unknown native physiological function that mediate the neurotoxic effects of alpha-latrotoxin, a potent toxin found in black widow spider venom. This receptor-toxin interaction has helped to elucidate the mechanistic aspects of neurotransmitter and hormone release in vertebrates. Such unprecedented discovery points to a new direction in the assessment of ADHD and suggest that further study of this receptor family may provide novel insights into the etiology and treatment of ADHD and other related psychiatric conditions.

AB Attention deficit hyperactivity disorder (ADHD) is the most common behavioral disorder in childhood, and often has effects detectable into adulthood. Advances in genetic linkage and association analysis have begun to elucidate some of the genetic factors underlying this complex disorder. Recently, we identified LPHN3, a novel ADHD susceptibility gene harbored in 4q, and showed that a LPHN3 common haplotype confers susceptibility to ADHD and predicts effectiveness of stimulant medication. Here we present the mutational analysis of the entire coding region of LPHN3 in a cohort of 139 ADHD subjects and 52 controls from across the USA. We identified 21 variants, of which 14 have been reported and 7 are novel. These include 5 missense, 8 synonymous, and 8 intronic changes. Interestingly, neither susceptibility nor protective haplotype alleles are associated with obviously significant coding region changes, or canonical splice site alterations, suggesting that non-coding variations determining the quantity and/or quality of LPHN3 isoforms are the likely contributors to this common behavioral disorder.

AB In a genome-wide linkage scan, we aimed at mapping risk loci for dyslexia in the German population. Our sample comprised 1,030 individuals from 246 dyslexia families which were recruited through a single-proband sib pair study design and a detailed assessment of dyslexia and related cognitive traits. We found evidence for a major dyslexia locus on chromosome 6p21. The cognitive trait rapid naming (objects/colors) produced a genome-wide significant LOD score of 5.87 (P = 1.00 x 10(-7)) and the implicated 6p-risk region spans around 10Mb. Although our finding maps close to DYX2, where the dyslexia candidate genes DCDC2 and KIAA0319 have already been identified, our data point to the presence of an additional risk gene in this region and are highlighting the impact of 6p21 in dyslexia and related cognitive traits.

AB Background: Early detection of individuals at high risk for chronic kidney disease (CKD) may aid prevention. Urinary levels of trefoil factor 3 (TFF3) are associated with acute kidney injury in animal models, but the association of TFF3 levels with incident CKD in humans is unknown. Methods: We conducted a case-control study nested within the Atherosclerosis Risk in Communities (ARIC) Study and the ARIC Carotid MRI Study to determine whether urinary TFF3 levels predict incident CKD over 8.6 years of follow-up. A total of 143 participants with incident CKD (eGFR decreasing by >= 25% to <60 ml/min/1.73 m(2)) were matched on age, sex and race to 143 non-cases. Results: Higher TFF3 levels at baseline were strongly associated with Black race, diabetes (both p = 0.002), and antihypertensive medication use (p = 0.02). Compared to participants with TFF3 levels in the lowest quartile, the odds ratio (OR) of incident CKD was 1.84 (95% confidence interval (CI): 0.80, 4.22) for individuals with TFF3 levels in the second quartile, 2.43 (95% CI: 1.06, 5.53) for the third quartile, and 2.77 (95% CI: 1.22, 6.28) for the fourth quartile (p trend = 0.02). Adjustment for covariates, including urinary albumin: creatinine ratio, did not markedly change the associations. Twofold higher TFF3 levels were strongly associated with incident CKD after adjustment for CKD risk factors (adjusted OR = 1.35; 95% CI: 1.11, 1.64). Conclusions: Higher urinary TFF3 levels may indicate ongoing repair of damage in the kidney. Additional studies are needed to confirm whether TFF3 can be useful as a marker of increased risk for CKD.

AB Introduction: Alemtuzumab and rabbit antithymocyte globulin (rATG) are being used with increasing frequency as induction agents in kidney transplantation. Using the US Renal Data Base System, we analyzed the safety profile of these agents in the elderly. Methods: In a cohort of patients transplanted from January 2000 to July 2009 and followed through 2009, we assessed the effect of induction on allograft loss and death among elderly recipients. Recipients were censored at dates of allograft loss, death or the end of study. Independent associations between induction agents and allograft loss or death were examined using multivariate analysis with forward stepwise Cox regression. Results: Among 130,402 patients with first transplants, 14,907 were age 65 years or older. 4,466 (30%), 3,049 (20.5%), 1,501 (10.1%), and 999 (6.7%) were induced with thymoglobulin, basiliximab, daclizumab, and alemtuzumab, respectively. After adjusting for baseline differences, induction with alemtuzumab was associated with an increased risk of graft loss and death, with an adjusted hazard ratio (AHR) of 1.26 (95% CI 1.08-1.48). Risk was also present at other age cutoffs [age >60 (AHR 1.16; 95% CI 1.03-1.31; p = 0.014), age >70 (AHR 1.43; 95% CI 1.13-1.81; p = 0.003) and age >75 (AHR 1.68; 95% CI 1.07-2.63; p = 0.024)]. Conclusions: In the elderly, alemtuzumab is associated with an escalating risk of death and graft loss in recipients of kidney transplantations. Copyright (C) 2011 S. Karger AG, Basel

AB Background: Glomerular podocyte number declines and urinary excretion of podocytes increases as kidney disease progresses in persons with type 2 diabetes mellitus (T2DM). Methods: Using high-power electron microscopy, we quantified podocyte detachment in T2DM. Results: We evaluated 106 glomeruli (range 1-6 per subject) from 40 Pima Indian subjects with T2DM enrolled in a clinical trial. On high-power electron micrographs, 35% of the subjects had no evidence of podocyte detachment. Among the remaining subjects, the median percentage of basement membrane with podocyte detachment was 0.62% (interquartile range = 0.32-1.52%). Conclusion: Podocyte detachment from the glomerular basement membrane has been described and measured in type 1 diabetes mellitus using a different method. We now document podocyte detachment microscopically and quantify it morphometrically in humans with T2DM. The findings offer quantitative histologic support to a potential mechanism for the functional impairment, and possibly the sclerosis of glomeruli, in diabetic glomerular injury.

AB Background/Aims: The relationship of circulating endogenous secretory receptor for advanced glycation end products (esRAGE) and chronic kidney disease (CKD) has not been well characterized. The aim of the study was to determine whether plasma esRAGE is associated with CKD and is predictive of developing CKD in older adults. Methods: The relationship between plasma esRAGE and CKD (more than stage 3 of the National Kidney Foundation classification; estimated glomerular filtration rate <60 ml/min/1.73 m(2)) and CKD over 6 years of follow-up was examined in a cross-sectional and prospective study design in 1,016 men and women, 6 65 years, in the InCHIANTI study, a population-based cohort study of aging in Tuscany, Italy. Results: At enrollment, 158 (15.5%) had CKD. Mean (SD) plasma esRAGE was 0.45 (0.24) ng/ml. Plasma esRAGE (ng/ml) was associated with CKD (odds ratio per 1 SD = 1.30; 95% CI 1.1-1.6; p < 0.005) in a multivariable logistic regression model, adjusting for potential confounders. Plasma esRAGE was an independent predictor of incident CKD over 6 years of follow-up (hazard ratio per 1 SD = 1.37; 95% CI 1.1-1.7; p < 0.008) in a multivariable Cox proportional hazards model, adjusting for potential confounders. Conclusions: Elevated plasma esRAGE is independently associated with CKD and is an independent predictor of incident CKD in older community-dwelling adults. Copyright (C) 2011 S. Karger AG, Basel

AB Background: Diabetic nephropathy (DN) is a leading cause of mortality and morbidity in patients with type 1 and type 2 diabetes. The multicenter FIND consortium aims to identify genes for DN and its associated quantitative traits, e.g. the urine albumin:creatinine ratio (ACR). Herein, the results of whole-genome linkage analysis and a sparse association scan for ACR and a dichotomous DN phenotype are reported in diabetic individuals. Methods: A genomewide scan comprising more than 5,500 autosomal single nucleotide polymorphism markers (average spacing of 0.6 cM) was performed on 1,235 nuclear and extended pedigrees (3,972 diabetic participants) ascertained for DN from African-American (AA), American-Indian (AI), European-American (EA) and Mexican-American (MA) populations. Results: Strong evidence for linkage to DN was detected on chromosome 6p (p = 8.0 x 10(-5) LOD = 3.09) in EA families as well as suggestive evidence for linkage to chromosome 7p in Al families. Regions on chromosomes 3p in AA, 7q in EA, 16q in AA and 22q in MA displayed suggestive evidence of linkage for urine ACR. The linkage peak on chromosome 22q overlaps the MYH9/APOL1 gene region, previously implicated in AA diabetic and nondiabetic nephropathies. Conclusion:These results strengthen the evidence for previously identified genomic regions and implicate several novel loci potentially involved in the pathogenesis of DN. Copyright (C) 2011 S.

AB Chikungunya virus (CHIKV), an emerging mosquitoborne Alphavirus, causes debilitating rheumatic disease in humans that can last for weeks to months. Starting in 2004, a CHIKV outbreak in the Indian Ocean region affected millions of people, and infected travelers introduced CHIKV to new regions. The pathogenesis of CHIKV is poorly understood, and no approved vaccines or specific therapies exist. A major challenge to the study of CHIKV disease is the lack of a small animal model that recapitulates the major outcomes of human infection. In this study, the pathogenesis of CHIKV in C57BL/6J mice was investigated using biological and molecular clones of CHIKV isolated from human serum (CHIKV SL15649). After 14-day-old mice were inoculated with CHIKV SL15649 in the footpad, they displayed reduced weight gain and swelling of the inoculated limb. Histologic analysis of hind limb sections revealed severe necrotizing myositis, mixed inflammatory cell arthritis, chronic active tenosynovitis, and multifocal vasculitis. Interestingly, these disease signs and viral RNA persisted in musculoskeletal tissues for at least 3 weeks after inoculation. This work demonstrates the development of a mouse model of CHIKV infection with clinical manifestations and histopathologic findings that are consistent with the disease signs of CHIKV-infected humans, providing a useful tool for studying viral and host factors that drive CHIKV pathogenesis and for evaluating potential therapeutics against this emerging viral disease.

AB This study was conducted to determine the following: (1) whether matrix metalloproteinase-1 (MMP-1) Is increased in systemic vessels of preeclamptic women, (2) whether this increase might be mediated by neutrophils, and (3) whether MMP-1 could be responsible for vascular dysfunction. Omental arteries and plasma were collected from healthy pregnant and preeclamptic women. Omental arteries were evaluated for gene and protein expression of MMP-1, collagen type la, tissue inhibitor of metalloproteinase-1, and vascular reactivity to MMP-1. Gene and protein expression levels were also evaluated in human vascular smooth muscle cells (VSMCs) co-cultured with activated neutrophils, reactive oxygen species, or tumor necrosis factor a. Vessel expression of MMP-1 and circulating MMP-1 levels were increased in preeclamptic women, whereas vascular expression of collagen or tissue inhibitor of metalloproteinase-1 were down-regulated or unchanged. In cultured VSMCs, the unbalance in collagen-regulating genes of preeclamptic vessels was reproduced by treatment with neutrophils, tumor necrosis factor a, or reactive oxygen species. Chemotaxis studies with cultured cells revealed that MMP-1 promoted recruitment of neutrophils via vascular smooth muscle release of interleukin-8. Furthermore, MMP-1 induced vasoconstriction via protease-activated receptor-1, whose expression was significantly increased in omental arteries of preeclamptic women and in VSMCs co-cultured with neutrophils. Collectively, these findings disclose a novel role for MMP-1 as a mediator of vasoconstriction and vascular dysfunction in preeclampsia.

First published October 29, 2010; doi:10.1152/ajplung.00095.2010.-Lymphangioleiomyomatosis (LAM) is characterized by cystic lung destruction, resulting from proliferation of smooth-muscle-like cells, which have mutations in the tumor suppressor genes TSC1 or TSC2. Among 277 LAM patients, severe disease was associated with hypoxia and elevated red blood cell indexes that accompanied reduced pulmonary function. Because high red cell indexes could result from hypoxemia-induced erythropoietin (EPO) production, and EPO is a smooth muscle cell mitogen, we investigated effects of EPO in human cells with genetic loss of tuberin function, and we found that EPO increased proliferation of human TSC2-/-, but not of TSC2+/-, cells. A discrete population of cells grown from explanted lungs was characterized by the presence of EPO receptor and loss of heterozygosity for TSC2, consistent with EPO involvement. In LAM cells from lung nodules, EPO was localized to the extracellular matrix, supporting evidence for activation of an EPO-driven signaling pathway. Although the high red cell mass of LAM patients could be related to advanced disease, we propose that EPO, synthesized in response to episodic hypoxia, may increase disease progression by enhancing the proliferation of LAM cells.

First published October 13, 2010; doi: 10.1152/ajprenal.00328.2010.-To address the hypothesis that sterile intraperitoneal (ip) catheters alone promote a progressive foreign body reaction (FBR), silicone catheters were surgically implanted in C57BL mice. Controls (CON) underwent sham operations. After 1-5 wk (E1-E5 for catheter-bearing mice), catheters were recovered, and the adherent cell layer (ACL) was separated and cultured to demonstrate sterility. Transperitoneal transport experiments were performed to determine the mass transfer coefficients of mannitol (MTCM) and albumin (MTCA) and the osmotic filtration flux (J(osm)). After euthanasia, tissue samples were analyzed for submesothelial thickness, angiogenesis, and cytokine immunohistochemistry (IHC). Progressive increases with time were observed in submesothelial thickness (mu m: CON, 18.8 +/- 12.3; E1, 46.1 +/- 20.0; E2, 72.0 +/- 17.9; E4, 97.3 +/- 20.0; E5, 131.7 +/- 10.3; P < 0.003), angiogenesis (no. of vessels/mm of peritoneum: CON, 10.7 +/- 9.4; E1, 15.4 +/- 15.6; E2, 27.0 +/- 14.0; E4, 39.8 +/- 15.7; E5, 90.1 +/- 8.1; P < 0.0003), MTCA (6.5 +/- 1.5 X 10(-5) cm/min, mean CON; 18.0 +/- 1.1 < 10(-5) cm/min, mean E1-E5, P < 0.0001), J(osm) (0.0013 +/- 0.0001 cm/min, mean CON; 0.0017 +/- 0.0001 cm/min, mean E1-E5, P < 0.01). No significant differences were found for MTCM. IHC demonstrated strong staining for all treated animals and correlated with the ACL. This mouse model demonstrates that ip silicone catheters result in progressive FBR, altering the submesothelial anatomy and transperitoneal transport, and will form the basis for mechanistic studies in genetically-altered animals.

AB Objectives. To investigate the association between walkability and obesity, we studied adults residing in Baltimore City, Maryland, in neighborhoods of varying racial and socioeconomic composition.
Methods. We conducted a cross-sectional study of 3493 participants from the study Healthy Aging in Neighborhoods of Diversity across the Life Span. We used the Pedestrian Environment Data Scan to measure neighborhood walkability in 34 neighborhoods of diverse racial and socioeconomic composition in which the study participants lived. Confirmatory factor analysis was used to determine walkability scores. Multilevel modeling was used to determine prevalence ratios for the association between walkability and obesity.
Results. Among individuals living in predominately White and high-socioeconomic status (SES) neighborhoods, residing in highly walkable neighborhoods was associated with a lower prevalence of obesity when compared with individuals living in poorly walkable neighborhoods, after adjusting for individual-level demographic variables (prevalence ratio-[PR]=0.58; P=<.001 vs PR=0.80; P=.004). Prevalence ratios were similar after controlling for the perception of crime, physical activity, and main mode of transportation. The association between walkability and obesity for individuals living in low-SES neighborhoods was not significant after accounting for main mode of transportation (PR=0.85; P=.060).
Conclusions. Future research is needed to determine how differences in associations by neighborhood characteristics may contribute to racial disparities in obesity. (Am J Public Health. 2011;101:S318-S324. doi:10.2105/AJPH.2009.187492)

AB In March 2010, the Environmental Protection Agency (EPA) collaborated with government and nongovernmental organizations to host a groundbreaking symposium, "Strengthening Environmental Justice Research and Decision Making: A Symposium on the Science of Disproportionate Environmental Health Impacts."
The symposium provided a forum for discourse on the state of scientific knowledge about factors identified by EPA that may contribute to higher burdens of environmental exposure or risk in racial/ethnic minorities and low-income populations. Also featured were discussions on how environmental justice considerations may be integrated into EPA's analytical and decision-making frameworks and on research needs for advancing the integration of environmental justice into environmental policymaking.
We summarize key discussions and conclusions from the symposium and briefly introduce the articles in this issue. (Am J Public Health. 2011;101:S19-S26. doi:10.2105/AJPH.2011.300368)

AB Chronic disease is the leading cause of death in the United States. Risk factors and work conditions can be addressed through health promotion aimed at improving individual health behaviors; health protection, including occupational safety and health interventions; and efforts to support the work family interface. Responding to the need to address chronic disease at worksites, the National Institutes of Health and the Centers for Disease Control and Prevention convened a workshop to identify research priorities to advance knowledge and implementation of effective strategies to reduce chronic disease risk. Workshop participants outlined a conceptual framework and corresponding research agenda to address chronic disease prevention by integrating health promotion and health protection in the workplace.

AB Problem
To better understand the immunoregulatory properties of trophoblasts, we have searched for small immunologically active carbohydrates derived from intact trophoblast-like cells.
Method of study
Using solid phase extraction coupled with HPLC and mass spectrometry methods, we have characterized a low molecular weight carbohydrate-rich fraction associated with JEG-3 cells. We have also tested the bioactivities of selected authentic oligosaccharides found in the oligosaccharide fraction.
Results
The most abundant components of the low molecular weight carbohydrate-rich fraction were maltotriose and maltotetraose, with detectable amounts of maltopentaose. When authentic maltooligosaccharides were tested using lymphocytes, IL-2 inhibition was observed. This activity was dependent upon the number of saccharide subunits, stereochemistry, and concentration. To further test maltooligosaccharide properties, maltopentose was attached to glass cover slips. Although spontaneous neutrophil motility was observed on unmodified and control surfaces, it was inhibited on maltooligosaccharide-derivatized surfaces.
Conclusion
Maltooligosaccharides are associated with the trophoblast's surface where they may exhibit immunoregulatory activities.

AB Rationale Flow volume loops (FVL) in some bilateral lung transplant (BLT) and heart-lung transplant (HLT) patients suggest variable extrathoracic obstruction in the absence of identifiable causes. These FVLs usually have supranormal expiratory and normal inspiratory flow rates (SUPRA pattern).
Objectives: Characterize the relationship of the SUPRA pattern to predicted donor and recipient lung volumes, airway size, and survival.
Methods: We performed a retrospective review of adult BLT/HLT patients. We defined the SUPRA FVL pattern as: (1) mid-vital capacity expiratory to inspiratory flow ratio (Ve50:Vi50) > 1.0, (2) absence of identifiable causes of extrathoracic obstruction, and (3) Ve50/FVC >= 1.5 s(-1). We calculated predicted total lung capacity (pTLC) ratio by dividing the donor pTLC by the recipient pTLC. We measured airway luminal areas on thoracic computer tomographic scans. We compared survival in patients with and without the SUPRA pattern.
Measurements and Main Results: The SUPRA FVL pattern occurred in 56% of the 89 patients who qualified for the analysis. The pTLC ratio of SUPRA and non-SUPRA patients was 1.11 and 0.99, respectively (P = 0.004). A higher pTLC ratio was correlated with increased probability of the SUPRA pattern (P = 0.0072). Airway luminal areas were larger in SUPRA patients (P = 0.009). Survival was better in the SUPRA cohort (P = 0.009).
Conclusions: The SUPRA FVL pattern was frequent in BLT/HLT patients. High expiratory flows in SUPRA patients could result from increased lung elastic recoil or reduced airway resistance, both of which could be caused by the pTLC mismatch. Improved survival in the SUPRA cohort suggests potential therapeutic approaches to improve outcomes in BLT/HLT patients.

AB OBJECTIVE. The purpose of this study was to assess predictors of MRI-identified septal delayed enhancement mass at the right ventricular (RV) insertion sites in relation to RV remodeling, altered regional mechanics, and pulmonary hemodynamics in patients with suspected pulmonary hypertension (PH).
SUBJECTS AND METHODS. Thirty-eight patients with suspected PH were evaluated with right heart catheterization and cardiac MRI. Ten age- and sex-matched healthy volunteers acted as controls for MRI comparison. Septal delayed enhancement mass was quantified at the RV insertions. Systolic septal eccentricity index, global RV function, and remodeling indexes were quantified with cine images. Peak systolic circumferential and longitudinal strain at the sites corresponding to delayed enhancement were measured with conventional tagging and fast strain-encoded MRI acquisition, respectively.
RESULTS. PH was diagnosed in 32 patients. Delayed enhancement was found in 31 of 32 patients with PH and in one of six patients in whom PH was suspected but proved absent (p = 0.001). No delayed enhancement was found in controls. Delayed enhancement mass correlated with pulmonary hemodynamics, reduced RV function, increased RV remodeling indexes, and reduced eccentricity index. Multiple linear regression analysis showed RV mass index was an independent predictor of total delayed enhancement mass (p = 0.017). Regional analysis showed delayed enhancement mass was associated with reduced longitudinal strain at the basal anterior septal insertion (r = 0.6, p < 0.01). Regression analysis showed that basal longitudinal strain remained an independent predictor of delayed enhancement mass at the basal anterior septal insertion (p = 0.02).
CONCLUSION. In PH, total delayed enhancement burden at the RV septal insertions is predicted by RV remodeling in response to increased afterload. Local fibrosis mass at the anterior septal insertion is associated with reduced regional longitudinal contractility at the base.

TI Cross-species comparison of orthologous gene expression in human bladder
cancer and carcinogen-induced rodent models
SO AMERICAN JOURNAL OF TRANSLATIONAL RESEARCH
LA English
DT Article
DE Human bladder cancer; rodent models; gene expression; proteomics; and
cross-species comparison
AB Genes differentially expressed by tumor cells represent promising drug targets for anti-cancer therapy. Such candidate genes need to be validated in appropriate animal models. This study examined the suitability of rodent models of bladder cancer in B6D2F1 mice and Fischer-344 rats to model clinical bladder cancer specimens in humans. Using a global gene expression approach cross-species analysis showed that 13 similar to 34% of total genes in the genome were differentially expressed between tumor and normal tissues in each of five datasets from humans, rats, and mice. About 20% of these differentially expressed genes overlapped among species, corresponding to 2.6 to 4.8% of total genes in the genome. Several genes were consistently dysregulated in bladder tumors in both humans and rodents. Notably, CNN1, MYL9, PDLIM3, ITIH5, MYH11, PCP4 and FMO5 were found to commonly downregulated; while TOP2A, CCNB2, KIF20A and RRM2 were up-regulated. These genes are likely to have conserved functions contributing to bladder carcinogenesis. Gene set enrichment analysis detected a number of molecular path-ways commonly activated in both humans and rodent bladder cancer. These pathways affect the cell cycle, HIF-1 and MYC expression, and regulation of apoptosis. We also compared expression changes at mRNA and protein levels in the rat model and identified several genes/proteins exhibiting concordant changes in bladder tumors, including ANXA1, ANXA2, CA2, KRT14, LDHA, LGALS4, SERPINA1, KRT18 and LDHB. In general, rodent models of bladder cancer represent the clinical disease to an extent that will allow successful mining of target genes and permit studies on the molecular mechanisms of bladder carcinogenesis.

DE Genetic mutations; cancer; diagnosis; therapy; oncogenes; tumor
suppressors; high through-put DNA sequencing; review
AB Although it is well-established that cancer is driven by genetic mutations resulting in the acquisition of oncogenes and the loss of tumor suppressors, until recently many of the genomic details remained obscure. As a result of recent high-throughput DNA sequencing, basic insights into the spectrum of protein coding mutations in many cancers are now known. These findings provide an unprecedented framework of understanding and present new avenues for diagnosis, treatment, and prevention of cancer. In this article we discuss several high impact areas of global sequencing projects including developing drugs that specifically target cancer cells, creating personalized tools for better treatment and monitoring, and developing pre-symptomatic diagnostic tests. Capitalizing on these and other advances represent a new turning point in the war on cancer.

AB The results of the IMPACT trial showed a significant reduction in cytomegalovirus disease with 200-day valganciclovir prophylaxis compared to the standard 100-day regimen with the same drug. These results may have the potential to change the standard of care in most transplant centers. However, we have concerns with the design, execution and statistical analysis of this trial. Our study aimed to describe each of these issues and to provide possible solutions for the better understanding of the IMPACT trial. We conclude that the IMPACT trial does not have the strength of evidence to change current clinical practice of 100-day cytomegalovirus prophylaxis. Further, based on all available evidence, we consider that another clinical trial to test 200-day CMV prophylaxis is not necessary.

AB Even though the surgical techniques and perioperative care have improved, blood transfusions are still often required for the patients undergoing pancreaticoduodenectomy (PD). But complications from blood transfusions, poor prognosis of blood transfused patients, cost, and availability of blood products demand transfusion free (TF) surgery in the PD patients. The purpose of this study is to compare clinical outcome of TF pancreaticoduodenectomy with transfusion-eligible (TE) PD. We had investigated the possibility of blood TF treatments for the patients who underwent PD from December 2005 to August 2007. There were 41 cases of PD performed by one surgeon with the same method: 14 patients of the TF group and 27 patients of the TE group. Most of the TF group patients received perioperative blood augmentation and intraoperative acute normovolemic hemodilution. The results of statistical analysis between TF and TE group showed that there were no statistical differences in intraoperative data and postoperative outcomes, except preoperative hemoglobin levels, type of operations, and transfusion amount. To our best knowledge, this is the first successful PD program in selected patients as a series of operations without blood transfusion. TF PD can be done successfully in selected patients without severe complications.

AB The combination of ion mobility with matrix-assisted laser desorption/ionization allows for the rapid separation and analysis of biomolecules in complex mixtures (such as tissue sections and cellular extracts), as isobaric lipid, peptide, and oligonucleotide molecular ions are pre-separated in the mobility cell before mass analysis. In this study, MALDI-IM MS is used to analyze gangliosides, a class of complex glycosphingolipids that has different degrees of sialylation. Both GD1a and GD1b, structural isomers, were studied to see the effects on gas-phase structure depending upon the localization of the sialic acids. A total ganglioside extract from mouse brain was also analyzed to measure the effectiveness of ion mobility to separate out the different ganglioside species in a complex mixture.

AB Culture of cells as three-dimensional (3D) aggregates can enhance in vitro tests for basic biological research as well as for therapeutics development. Such 3D culture models, however, are often more complicated, cumbersome, and expensive than two-dimensional (2D) cultures. This paper describes a 384-well format hanging drop culture plate that makes spheroid formation, culture, and subsequent drug testing on the obtained 3D cellular constructs as straightforward to perform and adapt to existing high-throughput screening (HTS) instruments as conventional 2D cultures. Using this platform, we show that drugs with different modes of action produce distinct responses in the physiological 3D cell spheroids compared to conventional 2D cell monolayers. Specifically, the anticancer drug 5-fluorouracil (5-FU) has higher anti-proliferative effects on 2D cultures whereas the hypoxia activated drug commonly referred to as tirapazamine (TPZ) are more effective against 3D cultures. The multiplexed 3D hanging drop culture and testing plate provides an efficient way to obtain biological insights that are often lost in 2D platforms.

AB Dye conjugation is a common strategy improving the surface enhanced Raman detection sensitivity of biomolecules. Reported is a proof-of-concept study of a novel surface enhanced Raman spectroscopic tagging strategy termed as acid-cleavable SERS tag (ACST) method. Using Rhodamine B as the starting material, we prepared the first ACST prototype that consisted of, from the distal end, a SERS tag moiety (STM), an acid-cleavable linker, and a protein reactive moiety. Complete acid cleavage of the ACST tags was achieved at a very mild condition that is 1.5% trifluoroacetic acid (TFA) aqueous solution at room temperature. SERS detection of this ACST tagged protein was demonstrated using bovine serum albumin (BSA) as the model protein. While the SERS spectrum of intact ACST-BSA was entirely dominated by the fluorescent signal of STM, quality SERS spectra can be readily obtained with the acid cleaved ACST-BSA conjugates. Separation of the acid cleaved STM from protein further enhances the SERS sensitivity. Current SERS detection sensitivity, achieved with the acid cleaved ACST-BSA conjugate is similar to 5 nM in terms of the BSA concentration and similar to 1.5 nM in ACST content. The dynamic range of the cleaved ACST-BSA conjugate spans four orders of magnitudes from similar to 10 nM to similar to 100 mu M in protein concentrations. Further improvement in the SERS sensitivity can be achieved with resonance Raman acquisition. This cleavable tagging strategy may also be used for elimination of protein interference in fluorescence based biomolecule detection.

AB Hydrophilic interaction chromatography (HILIC) liquid chromatography/mass spectrometry (LC/MS) is appropriate for all native and reductively aminated glycan classes. HILIC carries the advantage that retention times vary predictably according to oligosaccharide composition. Chromatographic conditions are compatible with sensitive and reproducible glycomics analysis of large numbers of samples. The data are extremely useful for quantitative profiling of glycans expressed in biological tissues. With these analytical developments, the rate-limiting factor for widespread use of HILIC LC/MS in glycomics is the analysis of the data. In order to eliminate this problem, a Java-based open source software tool, Manatee, was developed for targeted analysis of HILIC LC/MS glycan datasets. This tool uses user-defined lists of compositions that specify the glycan chemical space in a given biological context. The program accepts high-resolution LC/MS data using the public mzXML format and is capable of processing a large data file in a few minutes on a standard desktop computer. The program allows mining of HILIC LC/MS data with an output compatible with multivariate statistical analysis. It is envisaged that the Manatee tool will complement more computationally intensive LC/MS processing tools based on deconvolution and deisotoping of LC/MS data. The capabilities of the tool were demonstrated using a set of HILIC LC/MS data on organ-specific heparan sulfates.

ID GENECHIP EXPRESSION MEASURES
AB Recently, with the advent of the 7th edition of the AJCC Cancer Staging manual, at least one set of criteria (e.g. breast) were modified to now require the measurement of maximal depth of stromal invasion. With the current manual interpretive morphological approaches typically employed by surgical pathologists to assess tumor extent, the specialty now potentially has stumbled upon a crossroads of practice, where the diagnostic criteria have exceeded the capabilities of our commonly available tools. While whole slide imaging (WSI) technology holds the potential to offer many improvements in clinical workflow over conventional slide microscopy including unambiguous utility for facilitating quantitative diagnostic tasks with one important example being the determination of both linear dimension and surface area. However, the availability of histology data in digital form is of little utility if time-consuming and cumbersome manual workflow steps are necessarily imposed upon the pathologist in order to generate such measurements, especially as encountered with the complex and ill-defined shapes inherent to infiltrative tumors. In this communication, we demonstrate the utility of the recently described SIVQ algorithm to serve as the basis of a highly accurate, precise and semi-automated tool for direct surface area measurement of tumor infiltration from WSI data sets. By anticipating the current trend in cancer staging that emphasizes increasingly precise feature characterization, as witnessed by the recent publication of AJCC's 7th edition of the Cancer Staging Manual, this tool holds promise to will be of value to pathologists for clinical utility.

The constituents have been measured by multiple analytical methods with data contributed by NIST and by collaborating laboratories. This effort included the first use of isotope dilution mass spectrometry for value assignment of both fat-soluble vitamins (FSVs) and water-soluble vitamins (WSVs). Excellent agreement was obtained among the methods, with relative expanded uncertainties for the certified concentration values typically ranging from <2% to 15% for vitamins.

Androgen is required for androgen receptor translocation to the nucleus, interaction with androgen response elements, expression of target genes, and prostate cancer cell proliferation. The intra-tissue and serum testosterone and dihydrotestosterone levels are important biomarkers to monitor androgen deprivation therapy efficacy in prostate cancer and recurrent prostate cancer. We have measured testosterone and dihydrotestosterone in procured recurrent prostate cancer specimens using liquid chromatography tandem mass spectrometry. The measured androgen levels are sufficient to activate androgen receptor and suggest that the recurrent prostate cancer microenvironment is capable of intracrine androgen biosynthesis.

AB Synthetic zinc finger nucleases (ZFNs) are useful for the improvement of site directed integration of foreign gene into vertebrate chromosomes. To facilitate site-directed integration of foreign genes into the 3'-untranslated region of the chicken ovalbumin gene, we have constructed ZFN expression vectors using Zinc Finger Consortium Vector Kits and tested the functionality of these ZFN constructs. Coding sequences for 6 zinc fingers were assembled following the modular assembly method. The zinc finger assembly was fused to two FokI catalytic domains. Various configurations of linker regions between domains were tested for their influence on enzymatic activity, using plasmid substrate containing the target sequence. Results indicated that ZFN with an elongated linker between two nuclease domains had a high catalytic activity.

AB Stimulants such as cocaine and the amphetamines are widely abused due to their rewarding effects. Much of what we know about drug abuse and drug reward comes from research involving stimulants, and much of this research involves using drug self-administration as an animal model of drug abuse. In this chapter, the example of stimulant self-administration is used to illustrate: (1) the basic methodology of drug self-administration procedures and (2) the behavioral principles that apply to addiction and animal models of addiction. Many variations of the self-administration procedure have been developed to model specific aspects of drug abuse, to assess the rewarding effects of drugs, and to assess the effects of treatments. The chapter describes how these variations are devised by stipulating the behavioral requirements for receiving the drug (i.e., the schedule of reinforcement) and incorporating drug-related environmental cues analogous to those that Occur in the human drug-abuse environment.

TI Alterations in the transcriptome and antibiotic susceptibility of
Staphylococcus aureus grown in the presence of diclofenac
SO ANNALS OF CLINICAL MICROBIOLOGY AND ANTIMICROBIALS
LA English
DT Article
DE Diclofenac; S. aureus; antibiotic resistance; non-steroidal
anti-inflammatory drugs (NSAIDs)
AB Background: Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) which has been shown to increase the susceptibility of various bacteria to antimicrobials and demonstrated to have broad antimicrobial activity. This study describes transcriptome alterations in S. aureus strain COL grown with diclofenac and characterizes the effects of this NSAID on antibiotic susceptibility in laboratory, clinical and diclofenac reduced-susceptibility (Dc(RS)) S. aureus strains. Methods: Transcriptional alterations in response to growth with diclofenac were measured using S. aureus gene expression microarrays and quantitative real-time PCR. Antimicrobial susceptibility was determined by agar diffusion MICs and gradient plate analysis. Ciprofloxacin accumulation was measured by fluorescence spectrophotometry.
Results: Growth of S. aureus strain COL with 80 mu g/ml (0.2 x MIC) of diclofenac resulted in the significant alteration by >= 2-fold of 458 genes. These represented genes encoding proteins for transport and binding, protein and DNA synthesis, and the cell envelope. Notable alterations included the strong down-regulation of antimicrobial efflux pumps including mepRAB and a putative emrAB/qacA-family pump. Diclofenac up-regulated sigB (sigma(B)), encoding an alternative sigma factor which has been shown to be important for antimicrobial resistance. Staphylococcus aureus microarray metadatabase (SAMMD) analysis further revealed that 46% of genes differentially-expressed with diclofenac are also sigma(B)-regulated. Diclofenac altered S. aureus susceptibility to multiple antibiotics in a strain-dependent manner. Susceptibility increased for ciprofloxacin, ofloxacin and norfloxacin, decreased for oxacillin and vancomycin, and did not change for tetracycline or chloramphenicol. Mutation to Dc(RS) did not affect susceptibility to the above antibiotics. Reduced ciprofloxacin MICs with diclofenac in strain BB255, were not associated with increased drug accumulation.
Conclusions: The results of this study suggest that diclofenac influences antibiotic susceptibility in S. aureus, in part, by altering the expression of regulatory and structural genes associated with cell wall biosynthesis/turnover and transport.

AB PURPOSE: To describe trends in hypertension prevalence, awareness, treatment, and control among older Mexican Americans living in the Southwestern United States from 1993-1994 to 2004-2005.
METHODS: This study is a comparison between two separate cross-sectional cohorts of non-institutionalized Mexican Americans 75 years of age or older from the Hispanic Established Population for the Epidemiological Study of the Elderly (919 subjects from the 1993-1994 cohort and 738 from the 2004-2005 cohort). Data were collected on self-reported hypertension, measured blood pressure, medications, as well as sociodemographic and other health-related factors.
RESULTS: Hypertension prevalence increased from 73.0% in the period 1993-1994 to 78.4% in 2004-2005. Cross-cohort multivariate analyses showed that the higher odds of hypertension in the 2004-2005 cohort was attenuated by adding diabetes and obesity to the model. There was a significant increase in hypertension awareness among hypertensives (63.0% to 82.6%) and in control among treated hypertensives (42.5% to 55.4%). Cross-cohort multivariate analyses showed that the higher odds of control in 2004-2005 cohorts were accentuated by adding diabetes to the model. There were no significant changes in treatment rates (62.2% to 65.6%)
CONCLUSION: Hypertension prevalence in very old Mexican Americans residing in the Southwestern United States was higher in 2004-2005 than in 1993-1994 and was accompanied by a significant increase in awareness and control rates.

AB PURPOSE: In studies of the fetal origins of disease and life course epidemiology, measures of fetal exposure may be based on information reported by the adults who were exposed in utero. In particular, the full spectrum of consequences of in utero exposure to maternal tobacco smoking is now an area of active investigation, and the ability to report such exposure reproducibly is of interest. We evaluated the reproducibility of in utero exposure to tobacco smoke, reported by the adult daughter during consecutive pregnancies.
METHODS: This study was based on 11,257 women who enrolled for more than one pregnancy in the Norwegian Mother and Child Cohort Study (MoBa). Participants completed a questionnaire around 17 weeks of gestation, which asked about their in utero exposure to tobacco smoke. Kappa statistics were calculated. Determinants of agreement were evaluated using logistic regression.
RESULTS: Weighted Kappa for in utero exposure for the first and second reports was 0.80. Determinants of agreement were higher education (better) and longer time between reports (worse).
CONCLUSIONS: Information on in utero exposure to maternal tobacco smoking provided by adult women was highly reproducible in this population. Ann Epidemiol 2011;21:48-52. Published by Elsevier Inc.

AB Two mutational mechanisms are known to underlie Ullrich congenital muscular dystrophy (UCMD): heterozygous dominant negatively-acting mutations and recessively-acting loss-of-function mutations. We describe large genomic deletions on chromosome 21q22.3 as a novel type of mutation underlying recessively inherited UCMD in 2 families. Clinically unaffected parents carrying large genomic deletions of COL6A1 and COL6A2 also provide conclusive evidence that haploinsufficiency for COL6A1 and COL6A2 is not a disease mechanism for Bethlem myopathy. Our findings have important implications for the genetic evaluation of patients with collagen VI related myopathies as well as for potential therapeutic interventions for this patient population.

SO ANNALS OF THE RHEUMATIC DISEASES

ID ACETYLCHOLINE-RECEPTOR; ANTIMUSCARINIC ANTIBODIES
AB Objectives The detection of autoantibodies to the muscarinic receptor type 3 (M3R) in the serum of patients with Sjogrens syndrome (SS) by ELISA is controversial. A study was undertaken to test whether modification of M3R peptides could enhance the antigenicity and increase the detection of specific antibodies using an ELISA.
Methods A series of controlled ELISAs was performed with serum from 71 patients with SS and 37 healthy volunteers (HV) on linear, citrullinated and/or cyclised and multi-antigenic peptides (MAP) of the three extracellular M3R loops to detect specific binding.
Results Significant differences (p < 0.05) in optical density (OD) between serum from patients and HV were detected for a cyclised loop 1-derived peptide and the negative control peptide. Furthermore, there were no statistically significant differences between the frequency of positive patients (defined as OD > 2SDs above the mean of the HV) and HV on any of the peptides tested.
Conclusions Binding of serum from patients with SS to M3R-derived peptides does not differ from binding to a control peptide in an ELISA and no significant binding to M3R-derived peptides was found in the serum from individual patients compared with HV. These data suggest that peptide-based ELISAs are not sufficiently sensitive and/or specific to detect anti-MR3 autoantibodies.

AB Vibrational spectroscopy, commonly associated with IR absorption and Raman scattering, has provided a powerful approach for investigating interactions between biomolecules that make up cellular membranes. Because the IR and Raman signals arise from the intrinsic properties of these molecules, vibrational spectroscopy probes the delicate interactions that regulate biomembranes with minimal perturbation. Numerous innovative measurements, including nonlinear optical processes and confined bilayer assemblies, have provided new insights into membrane behavior. In this review, we highlight the use of vibrational spectroscopy to study lipid-lipid interactions. We also examine recent work in which vibrational measurements have been used to investigate the incorporation of peptides and proteins into lipid bilayers, and we discuss the interactions of small molecules and drugs with membrane structures. Emerging techniques and measurements on intact cellular membranes provide a prospective on the future of vibrational spectroscopic studies of biomembranes.

AB Understanding how cells of all types sense external and internal signals and how these signals are processed to yield particular responses is a major goal of biology. Genetically encoded fluorescent proteins (FPs) and fluorescent sensors are playing an important role in achieving this comprehensive knowledge base of cell function. Providing high sensitivity and immense versatility while being minimally perturbing to a biological specimen, the probes can be used in different microscopy techniques to visualize cellular processes on many spatial scales. Three review articles in this volume discuss recent advances in probe design and applications. These developments help expand the range of biochemical processes in living systems suitable for study. They provide researchers with exciting new tools to explore how cellular processes are organized and their activity regulated in vivo.

AB Over the past 14 years, ubiquitination has emerged as a centrally important mechanism governing the subcellular trafficking of proteins. Ubiquitination, interaction with sorting factors that contain ubiquitin-binding domains, and deubiquitination govern the itineraries of cargo proteins that include yeast carboxypeptidase S, the epithelial sodium channel ENaC, and epidermal growth factor receptor. The molecular structures and mechanisms of the paradigmatic HECT and RING domain ubiquitin ligases, of JAMM- and USP-domain-deubiquitinating enzymes, and of numerous ubiquitin-binding domains involved in these pathways have been worked out in recent years and are described.

AB Vocal communication mediated by speech and language is a uniquely human trait, and has served an important evolutionary role in the development of our species. Deficits in speech and language functions can be of numerous types, including aphasia, stuttering, articulation disorders, verbal dyspraxia, and specific language impairment; language deficits are also related to dyslexia. Most communication disorders are prominent in children, where they are common. A number of these disorders have been shown to cluster in families, suggesting that genetic factors are involved, but their etiology at the molecular level is not well understood. In the past decade, genetic methods have proven to be powerful for understanding these etiologies. Linkage studies and molecular genetic analyses in a large family containing multiple individuals affected with verbal dyspraxia led to the discovery of mutations in the FOXP2 gene. This gene encodes a forkhead domain transcription factor, a finding that has led researchers to a new avenue of investigation into the substrates and mechanisms that underlie human speech development. In studies of stuttering, linkage and candidate gene approaches in consanguineous families identified mutations in the lysosomal enzyme-targeting pathway genes GNPTAB, GNPTG, and NAGPA, revealing a role for inherited defects in cell metabolism in this disorder. In specific language impairment, linkage studies have identified several loci, and candidate gene association studies are making progress in identifying causal variants at these loci. Although only a small fraction of all cases of speech and language disorders can be explained by genetic findings to date, the significant progress made thus far suggests that genetic approaches will continue to provide important avenues for research on this group of disorders.

AB The IL-10 family of cytokines consists of nine members: IL-10, IL-19, IL-20, IL-22, IL-24, IL-26, and the more distantly related IL-28A, IL-28B, and IL-29. Evolutionarily, IL-10 family cytokines emerged before the adaptive immune response. These cytokines elicit diverse host defense mechanisms, especially from epithelial cells, during various infections. IL-10 family cytokines are essential for maintaining the integrity and homeostasis of tissue epithelial layers. Members of this family can promote innate immune responses from tissue epithelia to limit the damage caused by viral and bacterial infections. These cytokines can also facilitate the tissue-healing process in injuries caused by infection or inflammation. Finally, IL-10 itself can repress proinflammatory responses and limit unnecessary tissue disruptions caused by inflammation. Thus, IL-10 family cytokines have indispensable functions in many infectious and inflammatory diseases.

AB Multiple epidemiological studies have demonstrated associations between the human leukocyte antigen (HLA) loci and human immunodeficiency virus (HIV) disease, and more recently the killer cell immunoglobulin-like (KIR) locus has been implicated in differential responses to the virus. Genome-wide association studies have convincingly shown that the HLA class I locus is the most significant host genetic contributor to the variation in HIV control, underscoring a central role for CD8 T cells in resistance to the virus. However, both genetic and functional data indicate that part of the HLA effect on HIV is due to interactions between KIR and HLA genes, also implicating natural killer cells in defense against viral infection and viral expansion prior to initiation of an adaptive response. We review the HLA and KIR associations with HIV disease and the progress that has been made in understanding the mechanisms that explain these associations.

Here we present a detailed review of the methods used to create computational models and to conduct simulations of immune function. We provide descriptions of the key data-gathering techniques employed to generate the quantitative and qualitative data required for such modeling and simulation and summarize the progress to date in applying these tools and techniques to questions of immunological interest, including infectious disease. We include comments on what insights modeling can provide that complement information obtained from the more familiar experimental discovery methods used by most investigators and the reasons why quantitative methods are needed to eventually produce a better understanding of immune system operation in health and disease.

AB Dengue virus (DENV) is a mosquito-borne member of the Flavivirus genus and includes four serotypes (DENV-1, DENV-2, DENV-3, and DENV-4), each of which is capable of causing dengue fever and dengue hemorrhagic fever/dengue shock syndrome. Serious disease can be seen during primary infection but is more frequent following second infection with a serotype different from that of a previous infection. Infection with wild-type DENV induces high-titered neutralizing antibody that can provide long-term immunity to the homotypic virus and can provide short-term immunity (only several months duration) to a heterotypic DENV. The high level of virus replication seen during both secondary infection with a heterotypic virus and during primary DENV infection in late infancy is a direct consequence of antibody-dependent enhancement of replication. This enhanced virus replication is mediated primarily by preexisting, nonneutralizing, or subneutralizing antibodies to the virion surface antigens that enhance access of the virion-antibody complex to Fc gamma R-bearing cells. Vaccines will need to provide long-term protection against each of the four DENV serotypes by inducing neutralizing antibodies, and live, attenuated and various nonliving virus vaccines are in development.

AB The signaling lymphocyte activation molecule (SLAM)-associated protein, SAP, was first identified as the protein affected in most cases of X-linked lymphoproliferative (XLP) syndrome, a rare genetic disorder characterized by abnormal responses to Epstein-Barr virus infection, lymphoproliferative syndromes, and dysgammaglobulinemia. SAP consists almost entirely of a single SH2 protein domain that interacts with the cytoplasmic tail of SLAM and related receptors, including 2B4, Ly108, CD84, Ly9, and potentially CRACC. SLAM family members are now recognized as important immunomodulatory receptors with roles in cytotoxicity, humoral immunity, autoimmunity, cell survival, lymphocyte development, and cell adhesion. In this review, we cover recent findings on the roles of SLAM family receptors and the SAP family of adaptors, with a focus on their regulation of the pathways involved in the pathogenesis of XLP and other immune disorders.

AB For over seven decades, Coxiella burnetii, the causative agent of human Q fever, has been considered a prototypical obligate intracellular bacterium that relies exclusively on a eukaryotic cell for growth. Intracellularly, the organism prospers in an acidified, phagolysosome-like vacuole. C. burnetii has evolved to replicate in this harsh compartment by a mechanism involving acid activation of metabolism. The similar to 2Mb genome of C. burnetii is about twice the size of genomes of most obligate intracellular bacteria, and the organism's central metabolic pathways are largely intact. The absence of extensive genome reduction suggests the adaptation of C. burnetii to an obligate intracellular lifestyle is a recent evolutionary event. Indeed, insight from early work on C. burnetii metabolism, along with new information gained from metabolic pathway reconstructions, nutrient typing, and expression profiling, allowed the rescue of C. burnetii from its host cell to regain the axenic growth capacity of its ancestors. This advance removes the extensive experimental obstacles associated with intracellular obligatism and opens the door for a renaissance in C. burnetii research.

AB Under conditions of nutrient deprivation or stress, or as cells enter stationary phase, Escherichia coli and related bacteria increase the accumulation of RpoS, a specialized sigma factor. RpoS-dependent gene expression leads to general stress resistance of cells. During rapid growth, RpoS translation is inhibited and any RpoS protein that is synthesized is rapidly degraded. The complex transition from exponential growth to stationary phase has been partially dissected by analyzing the induction of RpoS after specific stress treatments. Different stress conditions lead to induction of specific sRNAs that stimulate RpoS translation or to induction of small-protein antiadaptors that stabilize the protein. Recent progress has led to a better, but still far from complete, understanding of how stresses lead to RpoS induction and what RpoS-dependent genes help the cell deal with the stress.

AB The basal ganglia are a chain of subcortical nuclei that facilitate action selection. Two striatal projection systems-so-called direct and indirect pathways-form the functional backbone of the basal ganglia circuit. Twenty years ago, investigators proposed that the striatum's ability to use dopamine (DA) rise and fall to control action selection was due to the segregation of D(1) and D(2) DA receptors in direct- and indirect-pathway spiny projection neurons. Although this hypothesis sparked a debate, the evidence that has accumulated since then clearly supports this model. Recent advances in the means of marking neural circuits with optical or molecular reporters have revealed a clear-cut dichotomy between these two cell types at the molecular, anatomical, and physiological levels. The contrast provided by these studies has provided new insights into how the striatum responds to fluctuations in DA signaling and how diseases that alter this signaling change striatal function.

AB Concerns exist about the adequacy of vitamin D in pregnant and lactating women. This review assesses the evidence that maternal vitamin D status influences maternal, fetal, and breast-fed infant bone health; maternal adverse outcomes (preeclampsia, gestational diabetes, obstructed labor, and infectious disease); fetal adverse outcomes (growth, gestational age, and developmental programming); and infant adverse outcomes. The evidence for all of these outcomes is contradictory (except for maternal infectious disease) and lacking causality; thus, it is inconclusive. The 2011 Dietary Reference Intakes for vitamin D and their implications for assessing vitamin D status are discussed. An estimated 5% to 29% of American pregnant women may have inadequate vitamin D status, with the higher prevalence in African Americans. Little is known about the prevalence of inadequacy in American lactating women. Research needs are also identified, especially the need for rigorous and well-designed randomized clinical trials to determine the role of vitamin D in nonbone health outcomes in pregnancy and lactation.

AB Human immunodeficiency virus (HIV) infection is generally characterized by inefficient viral transmission; an acute phase of intense viral replication and dissemination to lymphoid tissues; a chronic, often asymptomatic phase of sustained immune activation and viral replication; and an advanced phase of marked depletion of CD4(+) T cells that leads to acquired immune deficiency syndrome. Major insight into HIV transmission and each phase of infection has been gained from studies on blood and tissue specimens obtained from HIV-infected individuals, as well as from animal and ex vivo models. Not only has the introduction of effective antiretroviral therapy greatly diminished the morbidity and mortality associated with HIV disease progression, it has also provided new avenues of research toward delineating the mechanisms of HIV-induced pathogenesis. Further advances in therapeutics and informative technologies, combined with a better understanding of the immunologic and virologic components of HIV disease, hold promise for new preventative and even curative strategies.

PHARMACOLOGICAL CHARACTERIZATION
AB G protein-coupled receptors (GPCRs) are an evolutionarily conserved family of signaling molecules comprising approximately 2% of the human genome; this receptor family remains a central focus in basic pharmacology studies and drug discovery efforts. Detailed studies of drug action at GPCRs over the past decade have revealed existing and novel ligands that exhibit polypharmacology-that is, drugs with activity at more than one receptor target for which they were designed. These "off-target" drug actions can be a liability that causes adverse side effects; however, in several cases, drugs with less selectivity demonstrate better clinical efficacy. Here we review physical screening and cheminformatic approaches that define drug activity at the GPCR receptorome. In many cases, such profiling has revealed unexpected targets that explain therapeutic actions as well as off-targets underlying drug side effects. Such drug-receptor profiling has also provided new insights into mechanisms of action of existing drugs and has suggested directions for future drug development.

Solid-state nuclear magnetic resonance (NMR) methods have the unique capability of providing detailed structural constraints for amyloid fibrils, sufficient for the development of full molecular models. In this article, recent progress in the application of solid-state NMR to fibrils associated with Alzheimer's disease, prion fibrils, and related systems is reviewed, along with relevant developments in solid-state NMR techniques and technology.

AB Inhalational anthrax, a zoonotic disease caused by the inhalation of Bacillus anthracis spores, has a similar to 50% fatality rate even when treated with antibiotics. Pathogenesis is dependent on the activity of two toxic noncovalent complexes: edema toxin (EdTx) and lethal toxin (LeTx). Protective antigen (PA), an essential component of both complexes, binds with high affinity to the major receptor mediating the lethality of anthrax toxin in vivo, capillary morphogenesis protein 2 (CMG2). Certain antibodies against PA have been shown to protect against anthrax in vivo. As an alternative to anti-PA antibodies, we produced a fusion of the extracellular domain of human CMG2 and human IgG Fc, using both transient and stable tobacco plant expression systems. Optimized expression led to the CMG2-Fc fusion protein being produced at high levels: 730 mg/kg fresh leaf weight in Nicotiana benthamiana and 65 mg/kg in N. tabacum. CMG2-Fc, purified from tobacco plants, fully protected rabbits against a lethal challenge with B. anthracis spores at a dose of 2 mg/kg body weight administered at the time of challenge. Treatment with CMG2-Fc did not interfere with the development of the animals' own immunity to anthrax, as treated animals that survived an initial challenge also survived a rechallenge 30 days later. The glycosylation of the Fc (or lack thereof) had no significant effect on the protective potency of CMG2-Fc in rabbits or on its serum half-life, which was about 5 days. Significantly, CMG2-Fc effectively neutralized, in vitro, LeTx-containing mutant forms of PA that were not neutralized by anti-PA monoclonal antibodies.

AB Neurocysticercosis resulting from Taenia solium infections is a major cause of adult-acquired seizures worldwide. Disease is caused by larval cysts, and treatment consists of the anthelmintic drugs albendazole or praziquantel. There are no standard methods to assess drug activity to T. solium cysts in vitro. Morphological, functional, and biochemical changes that might reflect damaging (inhibiting, cytotoxic) drug effects were analyzed after exposure of cysts to albendazole sulfoxide (ABZ-SO), the major active metabolite of the drug in vivo, praziquantel (PZQ), or combinations of both. PZQ exposure led to a decrease in cyst size and inhibition of evagination, whereas ABZ-SO exposure resulted in minimal changes. Alkaline phosphatase (AP) is normally secreted by cysts, and both drugs inhibited AP secretion at concentrations of 5 and 50 ng/ml for PZQ and ABZ-SO, respectively. Some combinations of both drugs resulted in additive and/or synergistic activities. Parasite-specific antigen, detected in the cerebrospinal fluid and blood of infected patients, is also normally secreted by T. solium cysts. Antigen secretion was similarly inhibited by ABZ-SO and PZQ and a combination of both drugs, suggesting that inhibition of secretion is a common downstream consequence of the activities of both drugs. These studies establish quantitative methods to measure in vitro anthelmintic activity and suggest combination therapy with ABZ-SO and PZQ may have clinical benefit.

AB Rhesus macaques (Macaca mulatta) are genetically similar to humans and share many characteristics of aging and age-related diseases. They age at approximately three times the rate of humans and develop spontaneous cancers. In both humans and rhesus macaques, cancer incidence increases with age with the greatest incidence in those over 60 years of age and 20 years, respectively. The current survey reports on the incidence of spontaneous neoplasia in two colonies of captive rhesus macaques: the Wisconsin National Primate Research Center colony with 28 years of records and a National Institute on Aging colony with 21 years of records. When categorized by organ and histologic diagnosis, the average age at diagnosis was greater than 20 years for all categories except oral squamous cell carcinoma. Neoplasms of the gastrointestinal system were the most commonly diagnosed, accounting for 48.8% of the cases. Adenocarcinomas of the large intestine were the most prevalent tumor identified. Although there are differences in the biological behavior of cancer in the rhesus macaque when compared with humans, they are a valuable model of comparative oncology. Antioxid.

AB Here, we describe an HIV-infected patient with pretreatment resistance to raltegravir, nucleoside reverse transcriptase inhibitors, non-nucleoside reverse transcriptase inhibitors and protease inhibitors, and the ultimate ability to achieve viral suppression. Pretreatment integrase resistance testing is not routinely performed because transmitted integrase mutations conferring resistance to raltegravir are currently thought to be negligible. We suggest obtaining a pretreatment integrase genotype in patients with transmitted multiclass drug resistance in order to create an optimal first regimen and increase the chance for virological suppression.

AB Background: Information is lacking on outcomes in HIV-infected Brazilian women with CD4(+) T-cell counts >200 cells/mm(3) who initiate HAART for the prevention of mother-to-child transmission, and discontinue after delivery.
Methods: Clinical event rates after postpartum HAART discontinuation were calculated for all WHO stage 2-3 events, as well as for HIV progression warranting HAART re-initiation, defined by a WHO stage 4 event and/or CD4(+) T-cell decrease to <= 200 cells/mm(3). Predictors of the WHO stage 2-3 events and HIV progression outcomes were evaluated with Cox's proportional hazards models.
Results: A total of 120 women were followed for a mean of 1.5 years after delivery. Overall, 26 women had 30 events as follows: 20 developed WHO stage 2-3 events, yielding an incidence rate of 13/100 person-years (PY; 95% CI 8-20); 10 developed HIV progression requiring HAART re-initiation (incidence ratio 6/100 PY, 95% CI 3-11). Among progressors, a single woman developed a WHO stage 4 clinical event and the remainder had CD4(+) T-cell decreases. Women who had baseline CD4(+) T-cell counts between 200-500 cells/mm(3) had a hazard ratio for WHO stage 2-3 events of 2.5 compared to women with baseline >= 500 cells/mm(3) (95% CI 1.0-6.3; P=0.05). The only significant predictor of HIV progression was baseline CD4(+) T-cell count (hazard ratio 0.99, 95% CI 0.98-0.99; P=0.02).
Conclusions: In this observational study, a baseline CD4(+) T-cell count <500 cells/mm(3) was associated with an increased risk of postpartum WHO stage 2-3 clinical events and HIV disease progression. Randomized studies are needed to further evaluate the effect of postpartum treatment discontinuation on maternal health.

AB Background: Liver disease is a leading cause of mortality among HIV-infected persons in the United States and Europe. However, data regarding the effects of HIV and antiretroviral therapy (ART) on liver disease in Africa are sparse.
Methods: A total of 500 HIV-infected participants in an HIV care programme in rural Rakai, Uganda were frequency-matched by age, gender and site to 500 HIV-uninfected participants in a population cohort. All participants underwent transient elastography (FibroScan (R)) to quantify liver stiffness measurements (LSM) and identify participants with significant liver fibrosis, defined as LSM >= 9.3 kPa (approximate to Metavir F >= 2). Risk factors for liver fibrosis were identified by estimating adjusted prevalence risk ratios (adjPRR) and 95% CI using modified Poisson multivariate regression.
Results: The prevalence of hepatitis B coinfection in the study population was 5%. The prevalence of significant fibrosis was 17% among HIV-infected and 11% in HIV-uninfected participants (P=0.008). HIV infection was associated with a 50% increase in liver fibrosis (adjPRR 1.5, 95% CI 1.1-2.1; P=0.010). Fibrosis was also associated with male gender (adjPRR 1.4, 95% CI 1.0-1.9; P=0.045), herbal medicine use (adjPRR 2.0, 95% CI 1.2-3.3; P=0.005), heavy alcohol consumption (adjPRR 2.3, 95% CI 1.3-3.9; P=0.005), occupational fishing (adjPRR 2.5, 95% CI 1.2-5.3; P=0.019) and chronic HBV infection (adjPRR 1.7, 95% CI 1.0-3.1; P=0.058). Among HIV-infected participants, ART reduced fibrosis risk (adjPRR 0.6, 95% CI 0.4-1.0; P=0.030).
Conclusions: The burden of liver fibrosis among HIV-infected rural Ugandans is high. These data suggest that liver disease may represent a significant cause of HIV-related morbidity and mortality in Africa.

AB Background: Lactic acidosis (LA) is a potentially life-threatening complication of antiretroviral (ARV) therapy. Few randomized prospective studies have compared LA between different ARV regimens.
Methods: Characterization of cases of LA (serum lactate >5 mmol/l and arterial pH<7.35 or bicarbonate <20 mmol/l) and symptomatic hyperlactataemia (SH; serum lactate >2.2 mmol/l and symptoms) was made in a randomized open-label 2x2 factorial study of stavudine/lamivudine (d4T/3TC)-based versus didanosine/zidovudine-based therapy and lopinavir/ritonavir-based versus efavirenz (EFV)-based therapy in 1,771 HIV-infected adults initiating therapy between 2004 and 2008.
Results: The LA incident rate was 3.5/1,000 person-years (95% CI 1.8-5.9), and for combined LA/SH was 11.0/1,000 person-years (95% CI 7.9-14.9). There were two deaths (15% mortality) among 13 LA cases; all 11 survivors experienced symptom resolution and started new ARV regimens. LA cases were more likely to be female (OR 7.19, 95% CI 1.84-40.75; P=0.001) and had a higher body mass index (BMI; P<0.0001) compared with non-cases. There was no increase in LA according to ARV regimen, age or CD4(+) T-cell count at randomization. When combined, LA/SH cases (n=41) were more often female (OR 4.76, 95% CI 2.36-10.08; P<0.0001), had increased BMI (P<0.0001), were more likely to be assigned d4T/3TC (OR 3.17, 95% CI 1.50-7.28; P=0.001) and were more likely to be assigned EFV (OR 2.18, 95% CI 1.08-4.61; P=0.026).
Conclusions: Female sex and increased BMI were associated with severe LA in this large randomized trial of first-line ARV in South Africa. While female sex, increased BMI and d4T are previously described risk factors for the development of clinically significant lactate elevations, the independent risk associated with EFV is a novel observation warranting further investigation.

AB Background: Ritonavir-boosted lopinavir (LPV/RTV) alone has been evaluated as simplified maintenance therapy for HIV-1 infection, but there are concerns about greater potential for emergence of protease inhibitor (PI) resistance. The OK04 trial evaluated maintenance therapy with LPV/RTV alone versus standard therapy (ST) with two NRTIs plus LPV/RTV in 205 patients, of whom 15 had virological rebound by week 48 (11 versus 4 patients, respectively). We developed a single genome sequencing (SOS) assay of HIV-1 gag and protease to assess the emergence of low frequency drug-resistant variants during virological rebound.
Methods: Plasma samples from 15 subjects at virological rebound were analysed by SGS of HIV-1 gag and protease genes. A total of 45 SOS sequences were planned per sample, providing 90% power to detect variants comprising >5% of the virus population.
Results: Overall, 521 single sequences obtained from 13 patients (range 4-48 sequences/patient) revealed similar frequencies of major protease resistance mutations in samples from the LPV/RTV alone (3/11) and ST (3/4) arms (P=0.10), with a median number of minor protease resistance mutations of 3.0 versus 3.5, respectively (P=0.23). Median number of gag PI resistance mutations were similar between the LPV/RTV alone and ST arms at cleavage sites (3.0 versus 2.5; P=0.83), non-cleavage sites (21 versus 16.5; P=0.71) and the transframe protein-p6 pol region cleavage sites (4.0 versus 3.0; P=0.6).
Conclusions: Although more subjects with simplified maintenance therapy with LPV/RTV alone had virological rebound compared to the ST arm, this was not associated with more frequent emergence of variants encoding PI resistance mutations in gag or protease detected by SGS.

AB Background: Sex differences in the natural history of HIV infection may vary between resource-rich and resource-limited settings.
Methods: Baseline characteristics from a randomized clinical trial of treatment-naive subjects conducted at sites in Africa, Asia, the Caribbean, and North and South America were analysed to determine if there were significant differences by sex.
Results: Of the 1,571 participants, 740 (47.1%) were women. Women had higher mean screening CD4(+) T-cell counts (mean 15 cells higher; P<0.001), lower mean haemoglobin and creatinine clearance, a lower mean baseline HIV-1 viral load (4.85 log(10) versus 5.05 log(10) copies/ml; P<0.001) and were less likely to have a prior AIDS diagnosis than men. The sex difference in viral load was related to CD4(+) T-cell count; however, it was independent of country and persisted within the strata with CD4(+) T-cell count <200 cells/mm(3).
Conclusions: Women in resource-limited settings have lower levels of plasma HIV-1 RNA and appear to present for enrolment into clinical trials at an earlier stage of disease than men. The biological basis for lower viral load in women compared to men remains unexplained. It will be important to determine if the sex differences observed at baseline impact clinical outcomes once the PEARLS clinical trial is completed.

AB Background: Alternatives to the available stavudine-containing paediatric fixed-dose combination (FDC) tablets are rapidly needed due to concerns regarding the cumulative toxicity of long-term stavudine exposure. We report the bioavailability and short-term safety of a novel paediatric FDC tablet of zidovudine (ZDV)/lamivudine (3TC)/nevirapine (NVP; 30/15/28 mg) in HIV-infected children.
Methods: In this Phase I/II open-label pharmacokinetic study, 42 children weighing 6-30 kg treated with NVP-based HAART for >= 4 weeks were randomized to receive the FDC tablets (GPO-VIR Z30) or the liquid formulations. Dosing was weight-based. Intensive 12-h blood sampling was performed after 2 weeks; subjects then crossed-over to the alternate formulation at equal doses and sampling repeated 2 weeks later. Pharmacokinetic parameters were determined by non-compartmental analysis. Buccal-swab samples were collected for cytochrome P450 (CYP)2B6 polymorphism analysis.
Results: With the FDC tablet, the geometric mean (90% CI) area under the curve (AUC) for ZDV, 3TC and NVP was 1.58 (1.49-1.68), 7.78 (7.38-8.19) and 68.88 (62.13-76.36) mu g.h/ml, respectively. Rules for NVP therapeutic inadequacy were defined a priori, and despite lower NVP exposure with the tablet (P<0.001), the levels remained therapeutically adequate. ZDV AUC was similar between formulations. 3TC exposure was significantly higher with the tablet but comparable to historical data in adults and children taking branded tablets. While receiving the tablet, NVP AUC in children with CYP2B 516 GG (45%), GT (45%) and TT (10%) genotypes were 67.0, 74.5 and 106.4 mu g.h/ml, respectively (P=0.04).
Conclusions: Disparities in drug exposure between formulations were observed; however, the FDC tablet delivered therapeutically adequate exposures of each drug and could well play an important role in simplifying antiretroviral treatment for children.

AB Knowledge of the composition of a normal healthy gut microbiota during infancy is important for understanding the role of gut microbiota in disease. A limitation of previous studies is that they are based on infants who have been subject to factors, which can have a profound disruptive effect on the natural colonization process. We describe the colonization process, during the first 4 months after birth, in 85 infants who have experienced no major medical or dietary interventions. They were all vaginally delivered, healthy, term infants, who were not exposed to antibiotics, exclusively breastfed during their first month of life and at least partially breastfed up to 4 months. Selected microbial groups were identified by targeting small subunit microbial ribosomal RNA genes. In contrast to more recent studies, but in agreement with older studies, almost all our infants harbored gamma-Proteobacteria and Bifidobacterium. Yet undefined non-cultivable species belonging to Bacteroides, as well as microbes identified as Lachnospiraceae 2, were common. Strong associations were observed between some specific constituents of microbiota at day 4 and the concentration of specific microbial groups at day 120, indicating that early gut microbiota may influence later microbiota. Novel information of the undisturbed composition of early gut microbiota in babies is presented.

AB Clinical decision support (CDS) can improve safety, quality, and cost-effectiveness of patient care, especially when implemented in computerized provider order entry (CPOE) applications. Medication-related decision support logic forms a large component of the CDS logic in any CPOE system. However, organizations wishing to implement CDS must either purchase the computable clinical content or develop it themselves. Content provided by vendors does not always meet local expectations. Most organizations lack the resources to customize the clinical content and the expertise to implement it effectively. In this paper, we describe the recommendations of a national expert panel on two basic medication-related CDS areas, specifically, drug-drug interaction (DDI) checking and duplicate therapy checking. The goals of this study were to define a starter set of medication-related alerts that health-care organizations can implement in their clinical information systems. We also draw on the experiences of diverse institutions to highlight the realities of implementing medication decision support. These findings represent the experiences of institutions with a long history in the domain of medication decision support, and the hope is that this guidance may improve the feasibility and efficiency CDS adoption across healthcare settings.

AB Respiratory health is an important component of the ability to perform physically demanding work. The authors assessed respiratory symptom prevalence among Latino farmworkers engaged in crop production, and investigated work activities as risk factors for respiratory symptoms. During June to September 2008, 122 farmworkers completed up to 3 questionnaires. The authors estimated associations between work activities and wheezing symptoms using alternating logistic regression, controlling for age and smoking. At the first data collection, 29 (24%) farmworkers reported ever wheezing and 10 (8%) reported wheezing within the past month. Though not statistically significant, the odds of wheezing were elevated for individuals who reported performing tobacco-related work in the last 3 days. The odds were decreased among individuals who reported harvesting activities (odds ratio: 0.3, 95% confidence interval: 0.1, 1.0). Among Latino farmworkers, respiratory symptoms may be associated with work activities.

AB Adverse events (AEs) and serious adverse events (SAEs) are important outcomes of any intervention study yet are under-researched. Vague and variable definitions and substantial underreporting make comparisons of risk between studies difficult and evaluation of the safety of a particular intervention almost impossible. These realities may deter researchers from studying at-risk populations. Suicidal behavior is an adverse event in any study, and potentially a very serious one. Thus the issues of reporting and definition are particularly salient for researchers who work with populations at risk for suicidal behavior, especially when the suicidal behavior is the outcome of interest. We conducted a qualitative study with experienced suicide researchers and intervention experts to delineate the issues related to reporting serious adverse events faced by investigators conducting trials in suicide prevention. Participants from multiple sites were interviewed by phone, interviews transcribed and coded for definition and reporting issues and suggested solutions. A narrative synthesis was prepared and validated by all participants. Participants highlighted the difficulties in defining AEs and SAEs and stressed the importance and complexity of ensuring the AE was related to the study and reported properly, and were in agreement about the consequences of AEs to both institutions and individuals. Participants identified the need for the development of clear and consistent AE definitions and reporting requirements. Clear and consistently applied definitions of adverse and serious adverse events and reporting requirements would enhance the comparability of intervention studies in suicidal populations.

AB Introduction: Folate receptor beta (FR beta) is only detectable in placenta and limited to some hematopoietic cells of myeloid lineage in healthy people. Studies have indicated that FR beta is over-expressed in activated macrophages in autoimmune diseases and some cancer cells. In this study we aimed to develop an FR beta-specific human monoclonal antibody (mAb) that could be used as a therapeutic agent to treat rheumatoid arthritis and other autoimmune diseases, as well as FR beta positive cancers.
Methods: Functional recombinant FR beta protein was produced in insect cells and used as antigen to isolate a mAb, m909, from a human naive Fab phage display library. Binding of Fab and IgG1 m909 to FR beta was measured by ELISA, surface plasmon resonance, immune fluorescence staining, and flow cytometry. Antibody-dependent cell-mediated cytotoxicity (ADCC) was evaluated with FR beta positive CHO cells as target cells and isolated peripheral blood monocytes as effector cells in an in vitro assay.
Results: Fab m909 bound with relatively high affinity (equilibrium dissociation constant 57 nM) to FR beta. The IgG1 m909 showed much higher (femtomolar) avidity as measured by ELISA, and it bound to FR beta positive cells in a dose-dependent manner, but not to parental FR beta negative cells. m909 did not compete with folate for the binding to FR beta on cells. m909 was not only able to select FR beta positive, activated macrophages from synovial fluid cells of arthritis patients as efficiently as folate, but also able to mediate ADCC in FR beta positive cells.
Conclusions: Unlike folate-drug conjugates, m909 selectively binds to FR beta, does not recognize FR alpha, and has at least one effector function. m909 alone has potential to eliminate FR beta positive cells. Because m909 does not compete with folate for receptor binding, it can be used with folate-drug conjugates in a combination therapy. m909 can also be a valuable research reagent.

AB Introduction: The objective of this study is to determine if multiple systemic autoimmune diseases (SAID) share gene expression pathways that could provide insights into pathogenic mechanisms common to these disorders.
Methods: RNA microarray analyses (Agilent Human 1A(V2) 20K oligo arrays) were used to quantify gene expression in peripheral blood cells from 20 monozygotic (MZ) twin pairs discordant for SAID. Six affected probands with systemic lupus erythematosus (SLE), six with rheumatoid arthritis (RA), eight with idiopathic inflammatory myopathies (IIM), and their same-gendered unaffected twins, were enrolled. Comparisons were made between discordant twin pairs and these were also each compared to 40 unrelated control subjects (matched 2: 1 to each twin by age, gender and ethnicity) using statistical and molecular pathway analyses. Relative quantitative PCR was used to verify independently measures of differential gene expression assessed by microarray analysis.
Results: Probands and unrelated, matched controls differed significantly in gene expression for 104 probes corresponding to 92 identifiable genes (multiple-comparison adjusted P values < 0.1). Differentially expressed genes involved several overlapping pathways including immune responses (16%), signaling pathways (24%), transcription/translation regulators (26%), and metabolic functions (15%). Interferon (IFN)-response genes (IFI27, OASF, PLSCR1, EIF2AK2, TNFAIP6, and TNFSF10) were up-regulated in probands compared to unrelated controls. Many of the abnormally expressed genes played regulatory roles in multiple cellular pathways. We did not detect any probes expressed differentially in comparisons among the three SAID phenotypes. Similarly, we found no significant differences in gene expression when comparing probands to unaffected twins or unaffected twins to unrelated controls. Gene expression levels for unaffected twins appeared intermediate between that of probands and unrelated controls for 6535 probes (32% of the total probes) as would be expected by chance. By contrast, in unaffected twins intermediate ordering was observed for 84 of the 104 probes (81%) whose expression differed significantly between probands and unrelated controls.
Conclusions: Alterations in expression of a limited number of genes may influence the dysregulation of numerous, integrated immune response, cell signaling and regulatory pathways that are common to a number of SAID. Gene expression profiles in peripheral blood suggest that for genes in these critical pathways, unaffected twins may be in a transitional or intermediate state of immune dysregulation between twins with SAID and unrelated controls, perhaps predisposing them to the development of SAID given the necessary and sufficient environmental exposures.

AB Introduction: Rheumatic diseases are among the most common and debilitating health problems in the United States. These diseases are chronic, can result in severe decrements of physical and psychosocial functioning and affect patients' overall quality of life. A consensus regarding the best patient outcomes to be measured in randomized, controlled trials and prospective natural history studies is essential to provide best estimates of efficacy and safety of interventions across diverse patient populations.
Methods: Face-to-face English- and Spanish-language cognitive interviews were conducted among urban Hispanic and African American patients with rheumatic disease to develop a questionnaire booklet. Six measures validating patient-reported outcomes were included: the Arthritis Self-Efficacy Scale, the Stanford Health Assessment Questionnaire Disability Index, the Wong-Baker Faces Pain Scale, the Short Acculturation Scale, the Center for Epidemiologic Studies Depression Scale and the Inventory of Complementary and Alternative Medicine Practices. A sample of patients (n = 15) attending the National Institute of Arthritis and Musculoskeletal and Skin Diseases Community Health Center participated in the initial interviews. Revised measures were further tested for reliability in a separate sample of patients (n = 109) upon enrollment at the health center.
Results: Cognitive interviews provided feedback for questionnaire modifications and methods to enhance content validity and data quality, including discarding redundant questions, providing visual aids and concrete examples when appropriate and increasing the use of racially and ethnically concordant interviewers. The cognitive interviews further elucidated that some contextual assumptions and language usage in the original questionnaires may not have taken each respondent's environmental and sociocultural context into consideration. Internal reliability for previously tested measures remained high (Cronbach's alpha = 0.87-0.94).
Conclusions: Cognitive interviewing techniques are useful in a diverse sample of racial and ethnic minority patients with rheumatic disease as a method to assess the content validity of the specific outcome measures selected. The data collection approaches and methods described here ultimately enhance data quality. Vigilance is required in the selection of outcome measures in studies or in practice, particularly with each new language translation and/or culturally unique or diverse sample.

AB The study was embedded in Shanxi Province Cervical Cancer Screening Study II with the aim of examining the association between history of diagnosed tuberculosis or cervical inflammation and oncogenic human papillomavirus (HPV) infection, persistent oncogenic HPV infection, cervical intraepithelial neoplasia grade 3 or cervical cancer (CIN3+) in an isolated rural population of China. A total of 8,798 women were recruited for cervical cancer screening and an interviewer-administered questionnaire. Of the women in the study, 2.7% and 34% reported a diagnosis of tuberculosis and cervical inflammation, respectively. In the model for HPV infection, HPV persistence and CIN3+, we show an increasing magnitude of effect of tuberculosis with increasing severity of disease, as demonstrated by the increasing odds ratios from 1.68 for HPV positivity, to 1.75 for persistent HPV and then 2.08 for CIN3+. Women reporting a diagnosis of tuberculosis, cervical inflammation or both tuberculosis and cervical inflammation were at 75%, 22% and 113% higher odds of persistent HPV infection, respectively. One percent of the study population was diagnosed with tuberculosis and cervical inflammation, placing them at 90% and 113% higher odds of infection with HPV and persistent HPV, respectively. Tuberculosis and oncogenic HPV are identified for the first time as co-infections in rural unscreened women in Shanxi Province, China, highlighting the importance of infection history in assessing an individual's risk for HPV infection, persistence and CIN3+.

AB Background: We investigated effects of fenofibrate therapy on endothelial dysfunction and adipocytokine profiles.
Methods: A randomized, single-blind, placebo-controlled, cross-over study was conducted in 53 patients with primary hypertriglyceridemia. We administered placebo or fenofibrate 160 mg daily for 8 weeks.
Results: When compared with placebo, fenofibrate therapy substantially lowered plasma levels of TNF-alpha by 6 +/- 3% (P = 0.014) and hsCRP from 1.10 to 0.90 mg/l (P = 0.004). When compared with placebo, fenofibrate therapy increased plasma levels of adiponectin by 17 +/- 4% (P = 0.001), insulin sensitivity by 4 +/- 1% (as assessed by QUICKI, P = 0.009), and decreased plasma levels of leptin and resistin by 4 + 7% (P = 0.022) and 10 +/- 3% (P = 0.001), respectively. There were correlations between percent changes in QUICKI and percent changes in adiponectin levels (r = 0.279, P = 0.043) or leptin (r = -0.280, P = 0.042).
Conclusions: Fenofibrate therapy significantly reduced pro-inflammatory biomarkers and improved adipocytokines levels and insulin sensitivity in hypertriglyceridemic patients. (C) 2010 Elsevier Ireland Ltd. All rights reserved.

AB All bacterial cells need to protect themselves against the detrimental effects of reactive oxygen and reactive nitrogen species that are released by one species to inhibit another or are generated during normal metabolism, by antibiotics, or by other redox-active compounds. Although some prominent oxidative stress regulons have been studied for many years, the past 10 years have shown that there are more regulators and regulons than initially imagined. In addition, these recent studies have shown that there is variety in the chemistry by which proteins detect reactive oxygen and nitrogen species, although all of the sensing mechanisms involve reactive cysteine, histidine residues, or metals, predominantly iron. Overlap between the oxidative and nitrosative stress responses and other stress responses has always been known, but the recent studies have shown that the boundaries are even less clear than they were at the outset of the studies.

AB In response to nutritional limitation, bacteria stop growing and display major gene expression reprogramming in order to face the starvation and difficult times to come. In most bacteria, the first level of this response is the stringent response, mediated by the increase in (p)ppGpp nucleotides. (p)ppGpp controls growth by a variety of mechanisms depending on the bacteria, ranging from the global reprogramming of genes involved in growth or stress response by a direct or indirect modulation of RNA polymerase activity, to the inhibition of enzymes involved in cell cycle control. The (p)ppGpp levels in the cell are regulated by the widely conserved RelA/SpoT homolog enzymes, which synthesize or degrade (p)ppGpp in function of the nutritional quality of the environment.

AB Passive extraocular muscles (EOMs), like most biological tissues, are hyperelastic, that is, their stiffness increases as they are stretched. It has always been assumed, and in a few occasions argued, that this is their only nonlinearity and that it can be ignored in central gaze. However, using novel measurement techniques in anesthetized paralyzed monkeys, we have recently demonstrated that EOMs are characterized by another prominent nonlinearity: the forces induced by sequences of stretches do not sum. Thus, superposition, a central tenet of linear and quasi-linear models, does not hold in passive EOMs. Here, we outline the implications of this finding, especially in light of the common assumption that it is easier for the brain to control a linear than a nonlinear plant. We argue against this common belief: the specific nonlinearity of passive EOMs may actually make it easier for the brain to control the plant than if muscles were linear.

AB Saccade-generating burst neurons (BN) are inhibited by omnipause neurons (OPN), except during saccades. OPN activity pauses before saccade onset and resumes at the saccade end. Microstimulation of OPN stops saccades in mid-flight, which shows that OPN can end saccades. However, OPN pause duration does not correlate well with saccade duration, and saccades are normometric after OPN lesions. We tested whether OPN were responsible for stopping saccades both in late-onset Tay-Sachs, which causes premature saccadic termination, and in individuals with cerebellar hypermetria. We studied gaze shifts between two targets at different distances aligned on one eye, which consist of a disjunctive saccade followed by vergence. High-frequency conjugate oscillations during the vergence movements that followed saccades were present in all subjects studied, indicating OPN silence. Thus, mechanisms other than OPN discharge (e.g., cerebellar caudal fastigial nucleus-promoting inhibitory BN discharge) must contribute to saccade termination.

ID ACTIVATED CATION CURRENT; BURST NEURONS; EXCITABILITY
AB Conductance-based models of reciprocally inhibiting burst neurons suggest that intrinsic membrane properties and postinhibitory rebound (PIR) determine the amplitude and frequency of saccadic oscillations. Reduction of the low-threshold calcium currents (I-T) in the model decreased the amplitude but increased the frequency of the simulated oscillations. Combined reduction of hyperpolarization-activated cation current (I-h) and I-T in the model abolished the simulated oscillations. We measured the effects of a selective blocker of I-T (ethosuximide) in healthy subjects on the amplitude and frequency of saccadic oscillations evoked by eye closure and of a nonselective blocker of I-h and I-T (propronolol) in a patient with microsaccadic oscillation and limb tremor syndrome (mSOLT). Ethosuximide significantly reduced the amplitude but increased the frequency of the saccadic oscillations during eye closure in healthy subjects. Propranolol abolished saccadic oscillations in the mSOLT patient. These results support the hypothetical role of postinhibitory rebound, I-h, and I-T, in generation of saccadic oscillations and determining their kinematic properties.

AB Acquired pendular nystagmus (APN) occurs with multiple sclerosis (MS) and oculopalatal tremor (OPT); distinct features of the nystagmus have led to the development of separate models for their pathogenesis. APN in MS has been attributed to instability in the neural integrator, which normally ensures steady gaze. APN in OPT may result from electrotonic coupling between neurons in the hypertrophied inferior olivary nucleus, which induces maladaptive learning in cerebellar cortex. We tested these two hypotheses by analyzing the effects of gabapentin, memantine, and baclofen on both forms of nystagmus. No drug changed the dominant frequency of either form of APN, but the variability of frequency was affected with gabapentin and memantine in patients with OPT. The amplitude of APN in both MS and OPT was reduced with gabapentin and memantine, but not baclofen. Analyzing the effects of drug therapies on ocular oscillations provides a novel approach to test models of nystagmus.

AB Continued progress in language and learning disabilities (LDs) research requires a renewed focused on issues of etiology. Genetics research forms a central tenet of such an agenda and is critical in clarifying relationships among oral language development, acquisition of literacy and mathematics, executive function skills, and comorbid conditions. For progress to be made, diversified efforts must continue to emphasize molecular and behavioral genetics (including quantitative genetics) approaches, in concert with multi-disciplinary and multi-modal projects, to provide an integrated understanding of the behavioral and biological manifestations of language and learning disabilities. Critically, increased efforts to include ethnic, socio-economic, and linguistically diverse participant samples across a range of developmental stages is required to meet the public health needs of learners in the US and across the world. Taken together, this body of work will continue to enhance our understanding of LDs and help us move toward a truly prevention based approach to language and learning disabilities.

AB Variations in the serotonin transporter gene (5HTTLPR) and biased processing of face-emotion displays both have been implicated in the transmission of depression risk, but little is known about developmental influences on these relationships. Within a community sample of adolescents, we examine whether 5HTTLPR genotype moderates the link between maternal depressive history and errors in face-emotion labeling. When controlling for current levels of depression and anxiety among youth, a two-way interaction between maternal depressive history and 5HTTLPR genotype was detected. Specifically, adolescents whose mothers reported a depressive history and who had a low expressing genotype made more errors in classifying emotional faces when compared with adolescents with an intermediate or high expressing genotype, with or without maternal depression history. These findings highlight the complex manner in which maternal depression and genetic risk may interact to predict individual differences in social information processing. (C) 2010 Elsevier Ltd.

AB Despite the evidence for a communicative function of rodent scent marks and ultrasonic vocalizations, relatively little is known about the impact of social factors on these two forms of communication. Here, we tested the effects of two important social factors, prior exposure to a female and freshness of female urine, on male scent marks and ultrasonic vocalizations elicited by female urine. We also asked whether a recently reported strain difference between the highly social strain C57BL/6J (B6) and the mouse model of autism BTBR T+tf/J (BTBR) herein is specifically seen in response to female urine or also detectable in response to male urine traces. Results show that the emission of female urine-elicited ultrasonic vocalizations was dependent on previous female experience, while scent-marking behavior was not affected. A positive correlation was detected between scent-marking behavior and ultrasonic calling in the most biologically relevant context, male mice exposed to fresh female urine after female experience. Correlations were less prominent or missing in less biologically relevant contexts, e.g. in male mice exposed to fresh female urine without previous female experience, indicating that previous female experience is affecting both the emission of female urine-elicited ultrasonic vocalizations and the correlation between olfactory and acoustic communication. The strain difference in scent-marking behavior and ultrasonic calling between B6 and BTBR appears to be specific to female urine-elicited behavior as it was not seen in response to male urine traces, highlighting the relevance of the social context in which mouse communication is evaluated.

AB Catecholamines modulate endocrine stress reactivity by affecting regulatory influences of extra-hypothalamic brain structures on hypothalamus-pituitary-adrenal (HPA)-axis. Therefore, we aimed to investigate combined effects of functional allelic variations that affect dopamine availability in both cortical (COMTVal(158)Met polymorphism) and subcortical (DAT1 VNTR) brain regions on HPA-axis reactivity to psychosocial stress. By using a standardized laboratory stress task (public speaking) we obtained saliva cortisol samples during stress exposure and an extended recovery period in 100 healthy male adults. We report for the first time significant epistasis between COMT Val(158)Met and DAT1 VNTR on cortisol response patterns. Subjects homozygous for both the Met(158) and the 10-repeat allele of DAT1 VNTR were characterized by markedly elevated cortisol reactivity and impaired stress recovery compared to all other groups. Our results indicate a crucial role of functional genetic variants within the dopaminergic system in the modulation of HPA-axis response patterns and highlight the need to investigate combined effects of specific candidate genes on stress-related endophenotypes.

AB There is a large range of national public funding support for health research across countries. By contrast, allocations for overall funding for health literacy and related research areas are limited. Health research agendas and resource allocation are policy decisions that involve the use of power. There are strong incentives to maintain the status quo, especially in the face of level or declining funding. Many macro-and micro-level factors influence research agendas and funding support. These range from broader societal values and health care delivery systems, to the individuals themselves who make decisions. There is a great need for more research in areas such as implementation of simple interventions in "real-world" settings and the effects of communication technologies on receipt, processing, and seeking of health information by the public. There is some reason for optimism: awareness and support for more transdisciplinary and applied research relevant to health literacy is increasing, and some countries have adopted effective approaches to assess new health technology and treatment prior to introduction into clinical and public health practice.

AB eIF5A (eukaryotic translation initiation factor 5A) is the only cellular protein containing hypusine [N-epsilon-(4-amino-2-hydroxybutyl)lysine]. eIF5A is activated by the post-translational synthesis of hypusine and the hypusine modification is essential for cell proliferation. In the present study, we report selective acetylation of the hypusine and/or deoxyhypusine residue of eIF5A by a key polyamine catabolic enzyme SSAT1 (spermidine/spermine-N-1-acetyltransferase 1). This enzyme normally catalyses the N-1 -acetylation of spermine and spermidine to form acetyl-derivatives, which in turn are degraded to lower polyamines. Although SSAT1 has been reported to exert other effects in cells by its interaction with other cellular proteins, eIF5A is the first target protein specifically acetylated by SSAT1. Hypusine or deoxyhypusine, as the free amino acid, does not act as a substrate for SSAT1, suggesting a macromolecular interaction between eIF5A and SSAT1. Indeed, the binding of eIF5A and SSAT1 was confirmed by pull-down assays. The effect of the acetylation of hypusine on eIF5A activity was assessed by comparison of acetylated with non-acetylated bovine testis eIF5A in the methionyl-puromycin synthesis assay. The loss of eIF5A activity by this SSAT1-mediated acetylation confirms the strict structural requirement for the hypusine side chain and suggests a possible regulation of eIF5A by hypusine acetylation/deacetylation.

AB Enzymatic deamination of bases in DNA or RNA leads to an alteration of flow of genetic information. Adenosine deaminases edit RNA (ADARs, TADs). Specialized cytidine deaminases are involved in RNA/DNA editing in lipid metabolism (APOBEC1) and in innate (APOBEC3 family) and humoral (AID) immunity. APOBEC2 is required for proper muscle development and, along with AID, was implicated in demethylation of DNA. The functions of APOBEC4, APOBEC5, and other deaminases recently discovered by bioinformatics approaches are unknown. What is the basis for the diverse biological functions of enzymes with similar enzyme structure and the same principal enzymatic reaction? AID, APOBEC1, lamprey CDA1, and APOBEC3G enzymes cause uracil DNA glycosylase-dependent induction of mutations when overproduced ectopically in bacteria or yeast. APOBEC2, on the contrary, is nonmutagenic. We studied the effects of the expression of various deaminases in yeast and bacteria. The mutagenic specificities of four deaminases, hAID, rAPOBEC1, hAPOBEC3G, and lamprey CDA1, are strikingly different. This suggests the existence of an intrinsic component of deaminase targeting. The expression of yeast CDD1 and TAD2/TAD3, human APOBEC4, Xanthomonas oryzae APOBEC5, and deaminase encoded by Micromonas sp. gene MICPUN_56782 was nonmutagenic. A lack of a mutagenic effect for Cdd1 is expected because the enzyme functions in the salvage of pyrimidine nucleotides, and it is evolutionarily distant from RNA/DNA editing enzymes. The reason for inactivity of deaminases grouped with APOBEC2 is not obvious from their structures. This cannot be explained by protein insolubility and peculiarities of cellular distribution and requires further investigation.

AB Success of nanoparticle-mediated drug delivery is subject to development of optimal drug release strategies within defined space and time (triggered release). Recently, we reported a novel class of photo-triggerable liposomes prepared from dipalmitoyl phosphatidylcholine (DPPC) and photopolymerizable diacetylene phospholipid (DC8,9PC), that efficiently released entrapped calcein (a water soluble fluorescent dye) upon UV (254 nm) treatment. To develop these formulations for in vivo applications, we have examined phototriggering of these liposomes by visible light, and the effect of released anticancer drugs on cellular toxicity. Sonicated liposomes containing various ratios of DPPC:DC8,9PC and 4 mol% DSPE-PEG2000 were loaded with calcein (Ex/Em, 485/517 nm) or a chemotherapy drug, Doxorubicin (DOX, Ex/Em 490/590 nm). Our initial experiments showed that 514 nm laser treatment of liposomes containing 10 or 20 mol% DC8,9PC for 1-3 min resulted in significant release of calcein. Based on these results, we performed studies with DOX-loaded liposomes. First, biophysical properties (including liposome size and stability) and DOX encapsulation efficiency of the liposomes were determined. Subsequently, the effect of 514 nm laser on DOX release, and cellular toxicity by released DOX were examined. Since liposomes using the 86:10:04 mole ratio of DPPC: DC8,9PC:DSPE-PEG2000, showed highest encapsulation of DOX, these formulations were investigated further. We report that (i) liposomes retained about 70% of entrapped DOX at 37 degrees C in the presence of 0-50% serum. (ii) 514 nm laser treatment resulted in DOX release from liposomes in a wavelength-specific manner. (iii) Laser treatment of co-cultures containing DOX-loaded liposomes and cells (Raji and MCF-7) resulted in at least 2-3 fold improved cell killing as compared to untreated samples. Taken together, the photo-triggerable liposomes described here may provide a platform for future drug delivery applications. To our knowledge, this is the first report demonstrating improved cell killing following light-triggered release of an encapsulated anticancer agent from photosensitive liposomes.

AB Proper regulation of gene expression is essential for the differentiation, development and survival of all cells and organisms. Recent work demonstrates that transcription of many genes, including key developmental and stimulus-responsive genes, is regulated after the initiation step, by pausing of RNA polymerase II during elongation through the promoter-proximal region. Thus, there is great interest in better understanding the events that follow transcription initiation and the ways in which the efficiency of early elongation can be modulated to impact expression of these highly regulated genes. Here we describe our current understanding of the steps involved in the transition from an unstable initially transcribing complex into a highly stable and processive elongation complex. We also discuss the interplay between factors that affect early transcript elongation and the potential physiological consequences for genes that are regulated through transcriptional pausing.

VASCULATURE
AB Tumor endothelial marker 8 (TEM8) is an integrin-like cell surface protein upregulated on tumor blood vessels and a potential vascular target for cancer therapy. Here, we found that the ability of an anti-TEM8 antibody, clone SB5, to recognize the extracellular domain of TEM8 on the cell surface depends on other host-cell factors. By taking advantage of SB5's ability to distinguish different forms of cell surface TEM8, we identified alpha-smooth muscle actin and transgelin, an actin binding protein, as intracellular factors able to alter TEM8 cell surface structure. Overexpression of either of these proteins in cells converted TEM8 from an SB5-exposed to an SB5-masked form and protected cells from SB5-saporin immunotoxins. Because the predominant form of TEM8 on the cell surface is not recognized by SB5, we also developed a new monoclonal antibody, called AF334, which is able to recognize both the SB5-exposed and the SB5-masked forms of TEM8. AF334-saporin selectively killed TEM8-positive cells independent of TEM8 cell surface structure. These studies reveal that TEM8 exists in different forms at the cell surface, a structure dependent on interactions with components of the actin cytoskeleton, and should aid in the rational design of the most effective diagnostic and therapeutic anti-TEM8 monoclonal antibodies.

AB Previous global transcriptome and interactome analyses of copper-treated HepG2 cells identified hepatocyte nuclear factor 4 alpha (HNF4 alpha) as a potential master regulator of copper-responsive transcription. Copper exposure caused a decrease in the expression of HNF4 alpha at both mRNA and protein levels, which was accompanied by a decrease in the level of HNF4 alpha binding to its consensus DNA binding sequence. qRT-PCR and RNAi studies demonstrated that changes in HNF4 alpha expression ultimately affected the expressions of its down-stream target genes. Analysis of upstream regulators of HNF4 alpha expression, including p53 and ATF3, showed that copper caused an increase in the steady-state levels of these proteins. These results support a model for copper-responsive transcription in which the metal affects ATF3 expression and stabilizes p53 resulting in the down-regulation of HNF4 alpha expression. In addition, copper may directly affect p53 protein levels. The suppression of HNF4 alpha activity may contribute to the molecular mechanisms underlying the physiological and toxicological consequences of copper toxicity in hepatic-derived cells.

AB Neuroinflammation has been implicated in the pathogenesis or the progression of a variety of acute and chronic neurological and neurodegenerative disorders, including Alzheimer's disease. Prostaglandin H synthases or cyclooxygenases (COX -1 and COX-2) play a central role in the inflammatory cascade by converting arachidonic acid into bioactive prostanoids. In this review, we highlighted recent experimental data that challenge the classical view that the inducible isoform COX-2 is the most appropriate target to treat neuroinflammation. First, we discuss data showing that COX-2 activity is linked to anti-inflammatory and neuroprotective actions and is involved in the generation of novel lipid mediators with pro-resolution properties. Then, we review recent data demonstrating that COX-1, classically viewed as the homeostatic isoform, is actively involved in brain injury induced by pro-inflammatory stimuli including A beta, lipopolysaccharide, IL-1 beta, and TNF-alpha. Overall, we suggest revisiting the traditional views on the roles of each COX during neuroinflammation and we propose COX-1 inhibition as a viable therapeutic approach to treat CNS diseases with a marked inflammatory component.

AB Protein kinase C (PKC) is a critical cell signaling pathway involved in many disorders such as cancer and Alzheimer-type dementia. To date, evaluation of PKC ligand binding affinity has been performed by competitive studies against radiolabeled probes that are problematic for high-throughput screening. In the present study, we have developed a fluorescent-based binding assay system for identifying ligands that target the PKC ligand binding domain (C1 domain). An environmentally sensitive fluorescent dye (solvatochromic fluorophore), which has been used in multiple applications to assess protein-binding interactions, was inserted in proximity to the binding pocket of a novel PKC delta C1b domain. These resultant fluorescent-labeled delta C1b domain analogues underwent a significant change in fluorescent intensity upon ligand binding, and we further demonstrate that the fluorescent delta C1b domain analogues can be used to evaluate ligand binding affinity.

AB This chapter presents a technique that employs mutant glycosyltransferase enzymes for the site-specific bioconjugation of biomolecules via a glycan moiety to facilitate the development of a targeted drug delivery system. The target specificity of this methodology is based on unique sugar residues that are present on glycoproteins or engineered glycopeptides. The glycosyltransferases used in this approach have been manipulated in a way that confers the ability to transfer a modified sugar residue with a chemical handle to a sugar moiety of the glycoprotein or to a polypeptide tag of an engineered nonglycoprotein. The availability of the modified sugar moiety thus makes it possible to link cargo molecules at specific sites. The cargo may be comprised of for example, biotin or fluorescent tags for detection, imaging agents for magnetic resonance imaging (MRI), or cytotoxic drugs for cancer therapy.

AB Conjugates of bacterial polysaccharides covalently bound to a carrier protein are among licensed human vaccines. Immunization of adults and children with these vaccines results in induction of saccharide-specific antibodies composed mainly of the IgG class. Depending on the choice of coupling technique, saccharides can be attached to a protein by either multiple- or single-point attachments. While the first method is suitable for high molecular mass polysaccharides, the second one is beneficial for low-molecular mass compounds such as synthetic carbohydrates or bacterial oligosaccharides obtained by different degradation procedures. This chapter describes a method for coupling low-molecular mass lipopolysaccharide (LPS)-derived oligosaccharides composed of a core or a short O-specific polysaccharide-core fragment (O-SPC) to a carrier protein by a single-point attachment. Conjugation is performed between the carbonyl group of the reducing terminal of 3-deoxy-D-manno-oct-2-ulosonic acid (Kdo) exposed after acid hydrolyses of LPS and the aminooxy group of a bifunctional linker bound to the protein. This is an efficient reaction that can be carried out quickly and under mild conditions. Conjugates thus prepared using this approach preserve the external nonreducing end of the sugar chain and can induce antibodies to both conjugate components. Consequently, this method is highly suitable for the preparation of LPS-based human vaccines.

AB There is a large literature showing the detrimental effects of prenatal smoking on birth and childhood health outcomes. It is somewhat unclear, though, whether these effects are causal or reflect other characteristics and choices by mothers who choose to smoke that may also affect child health outcomes or biased reporting of smoking. In this paper, we use genetic markers that predict smoking behaviors as instruments to address the endogeneity of smoking choices in the production of birth and childhood health outcomes. Our results indicate that prenatal smoking produces more dramatic declines in birth weight than estimates that ignore the endogeneity of prenatal smoking, which is consistent with previous studies with non-genetic instruments. We use data from two distinct samples from Norway and the United States with different measured instruments and find nearly identical results. The study provides a novel application that can be extended to study several behavioral impacts on health and social and economic outcomes.

AB Liver cancer is one of the most common malignancies worldwide. Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) are the two most common primary liver cancers, yet there have been no significant advances in effective therapeutics. There is an urgent need to identify molecular targets for the development of novel therapeutic approaches. In this review, glypican-3 (GPC3) and mesothelin are discussed, with a focus on their potential as targets for antibody therapy in liver cancer. GPC3 and mesothelin are glycosylphosphatidylinositol-anchored proteins present on the cell surface. They are attractive candidates for liver cancer therapy given that GPC3 and mesothelin show high expression in HCC and CCA, respectively. Antibody drugs targeting GPC3 or mesothelin have shown anti-cancer activity in mice. Humanized or chimeric IgG molecules based on first-generation murine monoclonal antibodies against these antigens are being evaluated in clinical studies. Recently, fully human monoclonal antibodies against GPC3 and mesothelin have been isolated by antibody phage display technology that may provide opportunities for novel cancer therapy.

AB The ATP-binding cassette (ABC) transporter genes represent the largest family of transporters and these genes are abundant in the genome of all vertebrates. Through analysis of the genome sequence databases we have characterized the full complement of ABC genes from several mammals and other vertebrates. Multiple gene duplication and deletion events were identified in ABC genes in different lineages indicating that the process of gene evolution is still ongoing. Gene duplication resulting in either gene birth or gene death plays a major role in the evolution of the vertebrate ABC genes. The understanding of this mechanism is important in the context of human health because these ABC genes are associated with human disease, involving nearly all organ systems of the body. In addition, ABC genes play an important role in the development of drug resistance in cancer cells. Future genetic, functional, and evolutionary studies of ABC transporters will provide important insight into human and animal biology.

AB Microarrays are spatially ordered arrays with ligands chemically immobilized in discrete spots on a solid matrix, usually a microscope slide. Microarrays are a high-throughput large-scale screening system enabling simultaneous identification fa large number of labeled target molecules (up to several hundred thousand) that bind specifically to the immobilized ligands of the array. DNA microarrays represent a promising tool for clinical, environmental, and industrial microbiology since the technology allows relatively rapid identification of large number of genetic determinants simultaneously, providing detailed genomic level information regarding the pathogen species, including identification of their virulence-associated factors and the presence of antibiotic resistance genes. In this chapter, we describe key aspects and methodologies important for the development and use of DNA microarrays for microbial diagnostics.

AB Electron paramagnetic resonance (EPR) oximetry at 700 MHz operating frequency employing a surface coil resonator is used to assess tissue partial pressure of oxygen (pO(2)) using paramagnetic media whose linewidth and decay constant are related to oxygen concentration. Differences in extracellular and intracellular pO(2) in squamous cell carcinoma (SCC) tumor tissue were tested using several types of water-soluble paramagnetic media, which localize extracellularly or permeate through the cell membrane. The nitroxide carboxy-PROXYL (CxP) can only be distributed in blood plasma and extracellular fluids whereas the nitroxides carbamoyl-PROXYL (CmP) and TEMPOL (TPL) can permeate cell membranes and localize intracellularly. EPR signal decay constant and the linewidth of the intravenously administered nitroxides in SCC tumor tissues implanted in mouse thigh and the contralateral normal muscle of healthy mice breathing gases with different pO(2) were compared. The pO(2) in the blood can depend on the oxygen content in the breathing gas while tissue PO2 was not directly influenced by pO(2) in the breathing gas. The decay constants of CmP and TPL in tumor tissue were significantly larger than in the normal muscles, and lower linewidths of CmP and TPL in tumor tissue was observed. The SCC tumor showed intracellular hypoxia even though the extracellular pO(2) is similar to normal tissue in the peripheral region.

TI Exploring the Impact of Ketamine on the Experience of Illusory Body

RESPONSES
AB Background: Our sense of body ownership is profound and familiar, yet it may be misleading. In the rubber-hand illusion, synchronous tactile and visual stimulation lead to the experience that a rubber hand is actually one's own. This illusion is stronger in schizophrenia. Given the evidence that ketamine, a noncompetitive N-methyl-D-aspartate antagonist reproduces symptoms of schizophrenia, we sought to determine whether the rubber-hand illusion is augmented by ketamine.
Methods: We studied 15 healthy volunteers in a within-subjects placebo-controlled study. All volunteers carried out two versions of the rubber-hand task, each under both placebo and ketamine infusions. In one task, they saw a rubber hand being stroked in synchrony with tactile stimulation of their real, hidden hand. In the other, stroking of the real and rubber hands was asynchronous. We recorded subjective changes in sense of ownership, as well as participants' ability to localize their hidden hand.
Results: Ketamine was associated with significant increases in subjective measures of the illusion and in hand mislocalization. Although asynchronous visuotactile stimulation attenuates the strength of the illusion during both placebo and ketamine, there remained a significant illusory effect during asynchronous visuotactile stimulation under ketamine compared with placebo. The strength of the illusion during asynchronous visuotactile stimulation correlated with other subjective effects of the drug.
Conclusions: Ketamine mimics the perturbed sense of body ownership seen in schizophrenia, suggesting that it produces a comparable alteration in integration of information across sensory domains and in the subjective and behavioral consequences of such integration.

AB After the progress made during the genomics era, bioinformatics was tasked with supporting the flow of information generated by nanobiotechnology efforts. This challenge requires adapting classical bioinformatic and computational chemistry tools to store, standardize, analyze, and visualize nanobiotechnological information. Thus, old and new bioinformatic and computational chemistry tools have been merged into a new sub-discipline: nanoinformatics. This review takes a second look at the development of this new and exciting area as seen from the perspective of the evolution of nanobiotechnology applied to the life sciences. The knowledge obtained at the nano-scale level implies answers to new questions and the development of new concepts in different fields. The rapid convergence of technologies around nanobiotechnologies has spun off collaborative networks and web platforms created for sharing and discussing the knowledge generated in nanobiotechnology. The implementation of new database schemes suitable for storage, processing and integrating physical, chemical, and biological properties of nanoparticles will be a key element in achieving the promises in this convergent field. In this work, we will review some applications of nanobiotechnology to life sciences in generating new requirements for diverse scientific fields, such as bioinformatics and computational chemistry.

AB Steroid refractory chronic graft-versus-host disease (cGVHD) is associated with a significant morbidity and mortality. Although first-line treatment of cGVHD is based on controlled trials, second-line treatment is almost solely based on phase II trials or retrospective analyses. The consensus conference on clinical practice in cGVHD held in Regensburg aimed to achieve a consensus on the current evidence of treatment options as well as to provide guidelines for daily clinical practice. Treatment modalities are the use of steroids and calcineurin inhibitors as well as immunomodulating modalities (photopheresis, mTOR-inhibitors, thalidomide, hydroxychloroquine, vitamin A analogs, clofazimine), and cytostatic agents (mycophenolate mofetil, methotrexate, cyclophosphamide, pentostatin). Recent reports showed some efficacy of rituximab, alemtuzumab, and etanercept in selected patients. Moreover, tyrosine kinase inhibitors such as imatinib came into the field because of their ability to interfere with the platelet-derived growth factor (PDGF-R) pathway involved in fibrosis. An other treatment option is low-dose thoracoabdominal irradiation. Although different treatment options are available, the "trial-and-error system" remains the only way to identify the drug effective in the individual patient, and valid biomarkers are eagerly needed to identify the likelihood of response to a drug in advance. Moreover, the sparse evidence for most treatment entities indicates the urgent need for systematic evaluation of second-line treatment options in cGVHD.

AB Adoptively transferred T cells have shown activity in treating viral infections after hemopoietic transplantation and anti-tumor activity against some malignancies such as melanoma and lymphoma. Current research focuses on defining the optimum type of cell for transfer to improve persistence and genetically modifying infused T cells to augment function, overcome tumor evasion strategies and allow ablation should adverse effects occur.

AB Minimal residual disease (MRD), both before and after transplantation, is a clinically important yet relatively poorly defined aspect of allogeneic hematopoietic stem cell transplantation (alloHSCT). The clinical relevance of MRD in the context of alloHSCT has been demonstrated by its association with the development of clinical relapse. However, with the possible exception of chronic myeloid leukemia (CML), the specific techniques, timing, frequency, and clinical utility, relative to improvement in patient outcomes, for monitoring MRD in the setting of alloHSCT has yet to be clearly defined. A concise overview of monitoring techniques for detecting MRD, as well as treatment strategies and biological and clinical research initiatives for MRD suggested by the National Cancer Institute First International Workshop on the Biology, Prevention, and Treatment of Relapse after Allogeneic Hematopoietic Stem Cell Transplantation, is covered in this article.

AB Chronic granulomatous disease (CGD) is a rare primary immunodeficiency with X-linked or autosomal recessive inheritance involving defects in genes encoding phox proteins, which are the subunits of the phagocyte NADPH oxidase. This results in failure to produce superoxide anion and downstream antimicrobial oxidant metabolites and to activate antimicrobial proteases. Affected patients are susceptible to severe, life-threatening bacterial and fungal infections and excessive inflammation characterized by granulomatous enteritis resembling Crohn's disease and genitourinary obstruction. Early diagnosis of CGD and rapid treatment of infections are critical. Prophylaxis with antibacterial and mold-active antifungal agents and the administration of interferon-gamma has significantly improved the natural history of CGD. Currently, the only cure is allogeneic hematopoietic cell transplant (HCT), although there remains controversy as to which patients with CGD should get a transplant. Allele-based HLA typing of alternative donors, improved supportive care measures, and use of reduced toxicity conditioning have resulted in event-free survival (EFS) of at least 80% even with an unrelated donor and even better when the patient has no active infections/inflammation. Gene correction of CGD would eliminate the risks of graft-versus-host disease (GVHD) and the immunoablative chemotherapy required for allogeneic HCT. Based on gene therapy trials in patients with SCID-X1, ADA-SCID, and the early experience with CGD, it is clear that at least some degree of myeloablation will be necessary for CGD as there is no inherent selective growth advantage for gene-corrected cells. Current efforts for gene therapy focus on use of lentivector constructs, which are thought to be safer from the standpoint of insertional mutagenesis and more efficient in transducing hematopoietic stem cells (HSCs).

AB Human respiratory syncytial virus (RSV) is a ubiquitous pathogen that infects essentially everyone worldwide during infancy and early childhood and is a leading cause of paediatric hospitalization for respiratory disease. RSV also is a frequent cause of less severe disease in healthy adults and is an important cause of morbidity and mortality in the elderly and in severely immunosuppressed individuals. RSV is an enveloped non-segmented negative strand RNA virus classified in the Paramyxovridae family, and its genome organization is one of the more complex of this family. The genome includes: two separate genes encoding type I and type III interferon (IFN) antagonists (NS1 and NS2); a gene (M2) with two open reading frames encoding novel proteins (M2-1 and M2-2) involved in RNA synthesis; and a glycoprotein G that has a number of unusual features, including high sequence variability, heavy glycosylation, cytokine mimicry, and a shed form that helps the virus evade neutralizing antibodies. RSV is able to efficiently infect and cause disease in very young infants, with the peak of hospitalization at 2-3 months of age, despite the presence of maternally derived virus-neutralizing serum antibodies. RSV has a single serotype but is able to re-infect symptomatically throughout life without the need for significant antigenic change, although immunity from prior infection reduces disease. It is widely thought that re-infection is due to an ability of RSV to inhibit or subvert the host immune response, but this remains largely speculative. The development of an effective vaccine or specific antiviral therapy against RSV is considered a high priority, but these goals remain unfulfilled. RSV is notable for a historic vaccine failure: a formalin-inactivated RSV vaccine that was evaluated in infants and children in the 1960s was poorly protective and paradoxically primed for enhanced RSV disease upon subsequent natural RSV infection. However, RSV also is notable because of the development of a successful strategy for passive immunoprophylaxis of infants at high risk for serious RSV disease using an RSV-neutralizing monoclonal antibody (MAb).

AB Superparamagnetic Iron oxide (SPIO) nanoparticles are potential probes for noninvasive cell tracking but the design of safe probes coupled with high labeling efficiency is still an important objective for such application In this study an efficient SPIO probe has been developed for mesenchymal stem cells (MSCs) labeling and tracking Different from many other systems involving high molecular polycations we chose low molecular weight amphiphilic PEI2k to form stable nanocomplexes with SPIO nanoparticles The probe can hold multiple SPIO nanoparticles with a controlled clustering structure leading to much higher T(2) relaxivities compared to single SPIO nanoparticles Labeled MSCs are unaffected in their viability proliferation or differentiation capacity The iron uptake process in MSCs displays a time- and dose-dependent behavior Transmission electron microscopy reveals that the nanoprobes are internalized into the cytoplasm of MSCs Subcutaneous injection of the labeled MSCs dispersed in a collagen type I hydrogel showed strong image contrast against unlabeled cells under a clinical 3T magnetic resonance imaging (MRI) scanner up to 19 days post-transplantation This study provides an important alternative to label MSCs at optimized low dosages with high efficiency and the probe may be useful to label other biologically important cells for imaging studies (C) 2010 Elsevier Ltd All rights reserved

AB Vaccines based on recombinant proteins require adjuvant systems in order to generate Th1-type immune responses We have developed a vaccine adjuvant system using a viscous chitosan solution and inter-leukin (IL)-12 a Th1-inducing cytokine The chitosan solution is designed to create a depot of antigen and IL-12 at a subcutaneous injection site We measured the in vivo immune response of a vaccine containing 025 1 or 4 mu g murine IL-12 and 75 mu g ovalbumin (OVA) formulated in a 1 5% chitosan glutamate solution The chitosan/IL-12/OVA vaccine in comparison to chitosan/OVA IL-12/OVA or OVA alone elicited greater antigen-specific CD4(+) and CD8(+) T-cell responses as determined by CD4(+) splenocyte proliferation Th1 cytokine release CD8(+) T-cell interferon-gamma release and MHC class I peptide pentamer staining The combination of chitosan and IL-12 also enhanced IgG2a and IgG2b antibody responses to OVA Co-formulation of chitosan and IL-12 thus promoted the generation of a Th1 immune response to a model protein vaccine Published by Elsevier Ltd

AB Investigation of large nucleic acids (> 30 kDa) challenges the current limits of NMR spectroscopy. Extended helical regions in RNA and DNA increase correlation times more so than for proteins of comparable size, resulting in line broadening and reduced sensitivity. Also, the lower proton density and poor proton spectral dispersion in nucleic acids can reduce the effectiveness of traditional solution NMR methods in studies of large nucleic acids. These limitations represent a substantial hindrance to the future investigation of biologically relevant large nucleic acid structures. Herein we describe methods that have been implemented to help overcome these challenges and extend the size limits of nucleic acid NMR spectroscopy, including construct design, selective isotopic labeling, multi-dimensional NMR experiments and complementary techniques.

AB RNAs are versatile molecules and play important roles in various biological processes. Their functions are embedded in their structures and dynamics, yet there is little propensity correlation between a primary sequence of an RNA and its three-dimensional structure except in the case of simple RNA hairpins and the special case of tRNAs. Despite more than a decade of significant progress in both X-ray crystallography and NMR spectroscopy, structure determination and elucidation of large RNAs with complex folds, using either experimental, computational or combined approaches, remains a major interest as well as a challenge to the research community in contemporary biology. In this chapter we outline a new strategy for solution structure determination of RNA using restraints that are derived from experimental NMR measurements and small-angle X-ray scattering data. In addition, we present practical details on how to prepare RNA sample solutions for successful SAXS experiments.

AB The low-molecular-weight compound JRC-II-191 inhibits infection of HIV-1 by blocking the binding of the HIV-1 envelope glycoprotein gp120 to the CD4 receptor and is therefore an important lead in the development of a potent viral entry inhibitor. Reported here is the use of two orthogonal screening methods, GOLD docking and ROCS shape-based similarity searching, to identify amine-building blocks that, when conjugated to the core scaffold, yield novel analogs that maintain similar affinity for gp120. Use of this computational approach to expand SAR produced analogs of equal inhibitory activity but with diverse capacity to enhance viral infection. The novel analogs provide additional lead scaffolds for the development of HIV-1 entry inhibitors that employ protein-ligand interactions in the vestibule of gp120 Phe 43 cavity.

AB Several Hsp90 modulators have been identified including the N-terminal ligand geldanamycin (GDA), the C-terminal ligand novobiocin (NB), and the co-chaperone disruptor celastrol. Other Hsp90 modulators elicit a mechanism of action that remains unknown. For example, the natural product gedunin and the synthetic anti-spermatogenic agent H2-gamendazole, recently identified Hsp90 modulators, manifest biological activity through undefined mechanisms. Herein, we report a series of biochemical techniques used to classify such modulators into identifiable categories. Such studies provided evidence that gedunin and H2-gamendazole both modulate Hsp90 via a mechanism similar to celastrol, and unlike NB or GDA. (C) 2010 Published by Elsevier Ltd.

AB A series of 5'-halogenated resiniferatoxin analogs have been investigated in order to examine the effect of halogenation in the A-region on their binding and the functional pattern of agonism/antagonism for rat TRPV1 heterologously expressed in Chinese hamster ovary cells. Halogenation at the 5-position in the A-region of RTX and of 4-amino RTX shifted the agonism of parent compounds toward antagonism. The extent of antagonism was greater as the size of the halogen increased (I > Br > Cl > F) while the binding affinities were similar, as previously observed for our potent agonists. In this series, 5-bromo-4-amino RTX (39) showed very potent antagonism with K(i) (ant) = 2.81 nM, which was thus 4.5-fold more potent than 5'-iodo RTX, previously reported as a potent TRPV1 antagonist. Molecular modeling analyses with selected agonists and the corresponding halogenated antagonists revealed a striking conformational difference. The 3-methoxy of the A-region in the agonists remained free to interact with the receptor whereas in the case of the antagonists, the compounds assumed a bent conformation, permitting the 3-methoxy to instead form an internal hydrogen bond with the C4-hydroxyl of the diterpene.

AB Finasteride and epristeride both inhibit 5 alpha-reductase with high potency via competitive and non-competitive mechanism, respectively. A new hybrid of finasteride and epristeride was designed as a new 5a-reductase inhibitor based on combination principles in medicinal chemistry. Human 5 beta-reductase was chosen as a plausible surrogate of 5 alpha-reductase type II and the results indicate that although the hybrid compound possesses the main bulk of epristeride, its inhibitory mechanism is same as of finasteride. The hybrid turned out to be a potent 5 alpha-reductase inhibitor in low IC(50) ranges. Published by Elsevier Ltd.

AB Molecular processes depending on protein protein interactions can use consensus recognition sequences that possess defined secondary structures. Left-handed polyproline II (PPII) helices are a class of secondary structure commonly involved with cellular signal transduction. However, unlike a-helices, for which a substantial body of work exists regarding applications of ring-closing metathesis (RCM), there are few reports on the stabilization of PPII helices by RCM methodologies. The current study examined the effects of RCM macrocyclization on left-handed PPII helices involved with the SH3 domain-mediated binding of Sos1-Grb2. Starting with the Sos1-derived peptide "Ac-V(1-)P(2)-P(3)-P(4)-V(5)-P(6)-P(7)-R(8)-R(9)-R(10)-amide," RCM macrocyclizations were conducted using alkenyl chains of varying lengths originating from the pyrrolidine rings of the Pro(4) and Pro(7) residues. residues: The resulting macrocyclic peptide's showed increased helicity as indicated by circular dichroism and enhanced abilities to block Grb2-Sos1 interactions in cell lysate pull-down assays. The synthetic approach may be useful in RCM macrocyclizations, where maintenance of proline integrity at both ring junctures is desired.

MYCOPLASMAS; AMNIOTIC-FLUID; INTRAAMNIOTIC INFECTION
AB The genital mycoplasmas have been implicated in a number of adverse outcomes of pregnancy. Spontaneous preterm labour and preterm birth is an important contributor to perinatal mortality and morbidity. If Mycoplasma hominis plays an integral part in this problem, it is likely to contribute through its involvement with bacterial vaginosis. Ureaplasmas induce cytokines and inflammation, making a casual association compelling. The role of Mycoplasma genitalium and Mycoplasma fermentans is less clear, but M. genitalium is potentially pathogenic and should be treated if detected. There is considerable evidence for the role of M. hominis in post-partum and post-abortal sepsis, and for ureaplasmas causing chronic lung disease or death in very low birthweight infants. The role of the genital mycoplasmas in adverse outcomes of pregnancy is complicated by the presence or absence of bacterial vaginosis, and this association requires further research.

PREGNANCY
AB Human parvovirus B19 infection is widespread. Approximately 30-50% of pregnant women are nonimmune, and vertical transmission is common following maternal infection in pregnancy. Fetal infection may be associated with a normal outcome, but fetal death may also occur without ultrasound evidence of infectious sequelae. B19 infection should be considered in any case of nonimmune hydrops. Diagnosis is mainly through serology and polymerase chain reaction. Surveillance requires sequential ultrasound and Doppler screening for signs of fetal anaemia, heart failure and hydrops. Immunoglobulins, antiviral and vaccination are not yet available, but intrauterine transfusion in selected cases can be life saving.

AB Caesarean delivery is frequently complicated by surgical site infections, endometritis and urinary tract infection. Most surgical site infections occur after discharge from the hospital, and are increasingly being used as performance indicators. Worldwide, the rate of caesarean delivery is increasing. Evidence-based guidelines recommended the use of prophylactic antibiotics before surgical incision. An exception is made for caesarean delivery, where narrow-range antibiotics are administered after umbilical cord clamping because of putative neonatal benefit. However, recent evidence supports the use of pre-incision, broad-spectrum antibiotics, which result in a lower rate of maternal morbidity with no disadvantage to the neonate.

TI Documenting the location of prostate biopsies with image fusion
SO BJU INTERNATIONAL
LA English
DT Article
DE prostate cancer; MRI; TRUS-guided sextant biopsy; MRI-TRUS fusion;
biopsy mapping
ID MAPPING BIOPSY; CANCER
AB What's known on the subject? and What does the study add?
Currently, systematic prostate biopsies are obtained with minimal information about their actual location.
This study demonstrates that a electromagnetically tracked ultrasound probe can be used to guide biopsies into specific areas of the prostate. By registering the ultrasound to an MRI scan of the prostate, obtained prior to biopsy, it is possible to accurately map the location of biopsies. Thus, if a patient requires a repeat biopsy, or there is a question about whether a specific area of the prostate was sampled, this system can be used to more accurately guide biopsies in the future.
OBJECTIVE
To develop a system that documents the location of transrectal ultrasonography (TRUS)-guided prostate biopsies by fusing them to MRI scans obtained prior to biopsy, as the actual location of prostate biopsies is rarely known.
PATIENTS AND METHODS
Fifty patients (median age 61) with a median prostate-specific antigen (PSA) of 5.8 ng/ml underwent 3T endorectal coil MRI prior to biopsy. 3D TRUS images were obtained just prior to standard TRUS-guided 12-core sextant biopsies wherein an electromagnetic positioning device was attached to the needle guide and TRUS probe in order to track the position of each needle pass. The 3D-TRUS image documenting the location of each biopsy was fused electronically to the T2-weighted MRI. Each biopsy needle track was marked on the TRUS images and these were then transposed onto the MRI. Each biopsy site was classified pathologically as positive or negative for cancer and the Gleason score was determined.
RESULTS
The location of all (n = 605) needle biopsy tracks was successfully documented on the T2-weighted (T2W) MRI. Among 50 patients, 20 had 56 positive cores. At the sites of biopsy, T2W signal was considered 'positive' for cancer (i.e. low in signal intensity) in 34 of 56 sites.
CONCLUSION
It is feasible to document the location of TRUS-guided prostate biopsies on pre-procedure MRI by fusing the pre-procedure TRUS to an endorectal coil MRI using electromagnetic needle tracking. This procedure may be useful in documenting the location of prior biopsies, improving quality control and thereby avoiding under-sampling of the prostate as well as directing subsequent biopsies to regions of the prostate not previously sampled.

AB Background: End-stage renal disease patients experience significant impairments in health-related quality of life (HRQOL). Testing various strategies to improve patient HRQOL in multicenter clinical trials, such as the Frequent Hemodialysis Network (FHN) trials is vitally important. Aims: The aim of this paper is to describe the design and conduct of HRQOL and patient-reported outcomes (PRO) assessment in the FHN trials. Methods: In the FHN trials, HRQOL was examined as a multidimensional concept, and the SF-36 RAND Physical Health Composite score was one of the co-primary outcomes. The instruments completed to assess HRQOL included the Medical Outcomes Study Short Form SF-36, Health Utilities Index 3, Sleep Problems Index, Beck Depression Inventory and feeling thermometer. These instruments have been shown to have high reliability, validity and responsiveness to change in the end-stage renal disease population. Additional items evaluating PRO including sexual function, time to recovery after dialysis and patients' self-perceived burden to caregiver were also assessed. All questionnaires were administered by trained interviewers using computer-assisted telephone interviewing to ensure blinding and minimizing selection bias. Interim analysis reveals that these instruments can be used to collect a comprehensive set of HRQOL measures with minimal patient burden. Conclusions: Accurate measurement of HRQOL and PRO can help us test whether hemodialysis interventions improve the health and well-being of this compromised patient population. We have shown that a comprehensive set of HRQOL measures can be centrally collected through telephone interviews in a blinded fashion, in a way that is well tolerated with minimum respondent burden.

TI A Phase I study evaluating the safety and immunogenicity of MVA85A, a
candidate TB vaccine, in HIV-infected adults
SO BMJ OPEN
LA English
DT Article
AB Objectives: Control of the tuberculosis (TB) epidemic is a global health priority and one that is likely to be achieved only through vaccination. The critical overlap with the HIV epidemic requires any effective TB vaccine regimen to be safe in individuals who are infected with HIV. The objectives of this clinical trial were to evaluate the safety and immunogenicity of a leading candidate TB vaccine, MVA85A, in healthy, HIV-infected adults.
Design: This was an open-label Phase I trial, performed in 20 healthy HIV-infected, antiretroviral-naive subjects. Two different doses of MVA85A were each evaluated as a single immunisation in 10 subjects, with 24 weeks of follow-up. The safety of MVA85A was assessed by clinical and laboratory markers, including regular CD4 counts and HIV RNA load measurements. Vaccine immunogenicity was assessed by ex vivo interferon gamma (IFN-gamma) ELISpot assays and flow-cytometric analysis.
Results: MVA85A was safe in subjects with HIV infection, with an adverse-event profile comparable with historical data from previous trials in HIV-uninfected subjects. There were no clinically significant vaccine-related changes in CD4 count or HIV RNA load in any subjects, and no evidence from qPCR analyses to indicate that MVA85A vaccination leads to widespread preferential infection of vaccine-induced CD4 T cell populations. Both doses of MVA85A induced an antigen-specific IFN-gamma response that was durable for 24 weeks, although of a lesser magnitude compared with historical data from HIV-uninfected subjects. The functional quality of the vaccine-induced T cell response in HIV-infected subjects was remarkably comparable with that observed in healthy HIV-uninfected controls, but less durable.
Conclusion: MVA85A is safe and immunogenic in healthy adults infected with HIV. Further safety and efficacy evaluation of this candidate vaccine in TB-and HIV-endemic areas is merited.

TI Effects of statin medication on mortality risk associated with type 2
diabetes in older persons: the population-based AGES-Reykjavik Study
SO BMJ OPEN
LA English
DT Article
AB Objective: To examine if the beneficial effect of statin medication on mortality seen in randomised clinical trials of type 2 diabetes applies equally to observational studies in the general population of older people.
Design: A prospective, population-based cohort study.
Setting: Reykjavik, Iceland.
Participants: 5152 men and women from the Age, Gene/Environment Susceptibility-Reykjavik Study, mean age 77 years, range of 66-96 years.
Main outcome measure: Cardiovascular and all-cause mortalities and the RR of dying according to statin use and history of coronary heart disease (CHD) in persons with type 2 diabetes and those without diabetes with a median follow-up time of 5.3 years, until end of 2009.
Results: The prevalence of type 2 diabetes was 12.4% of which 35% used statins. Statin use was associated with a 50% (95% CI 8% to 72%) lower cardiovascular mortality and 53% (29% to 68%) lower all-cause mortalities in persons with diabetes. For those without diabetes, statin use was associated with a 16% (-24% to 43%) lower cardiovascular and 30% (11% to 46%) lower all-cause mortalities. Persons with diabetes using statins had a comparable risk of cardiovascular and all-cause mortality to that of the general population without diabetes. The effect was independent of the level of glycaemic control.
Conclusion: This observational study lends important support to existing data from randomised clinical trials. These data suggest that in the general population of older people with diabetes, statin medication markedly reduces the excess cardiovascular and all-cause mortality risk, irrespective of the presence or absence of coronary heart disease or glucose-lowering medication.

AB Dyskeratosis congenita (DC) is characterized by reticular skin pigmentation, oral leukoplakia and abnormal nails. Patients with DC have very short telomeres and approximately one-half have mutations in telomere biology genes. A majority of patients with DC develop BM failure (BMF). Hematopoietic cell transplantation (HCT) represents the only known cure for BMF in DC, but poses significant toxicities. We report six patients who underwent allogeneic HCT with a novel nonmyeloablative conditioning regimen specifically designed for DC patients. Graft sources included related PBSCs (1), unrelated BM (2) and unrelated double umbilical cord blood (3). Complete donor engraftment was achieved in five of six patients. One patient had initial autologous hematopoietic recovery, which was followed by a second transplant that resulted in 88% donor chimerism. With a median follow-up of 26.5 months, four patients are alive, three of whom were recipients of unrelated grafts. We conclude with this small study that encouraging short-term survival can be achieved with HCT in patients with DC using a preparative regimen designed to promote donor engraftment and minimize life-threatening disease-specific complications such as pulmonary fibrosis. Long-term follow-up will be crucial with respect to individualized patient care with each of the transplanted individuals.

AB In the previous issue of Breast Cancer Research, Gardner and co-workers describe a novel interaction between Geminin, a protein that prevents reinitiation of DNA replication, and Topoisomerase II alpha (TopoII alpha), an enzyme essential for removing catenated intertwines between sister chromatids. Geminin facilitates the action of TopoII alpha, thereby promoting termination of DNA replication at the same time it inhibits initiation. In this manner, Geminin ensures that cells duplicate their genome once, but only once, each time they divide. Remarkably, either depletion of Geminin or overexpression of Geminin inhibits the action of TopoII alpha, thereby making Geminin an excellent target for cancer chemotherapy.

ID METABOLISM
AB Exemplified by the cancer cell's preference for glycolysis (the Warburg effect), altered metabolism has taken centerstage as an emerging hallmark of cancer. Charting the landscape of cancer metabolic addictions should reveal new avenues for therapeutic attack. Two recent studies found subsets of human melanoma and breast cancers to have high levels of phosphoglycerate dehydrogenase (PHGDH), a key enzyme for serine biosynthesis, and these cancer cells are dependent on PHGDH for their growth and survival. Tumors may thus harbor distinct metabolic alterations to support their malignancy, and targeting enzymes such as PHGDH might prove a viable therapeutic strategy in this scenario.

AB Introduction: Studies suggest that high circulating levels of prolactin increase breast cancer risk. It is unclear if genetic variations in prolactin (PRL) or prolactin receptor (PRLR) genes also play a role. Thus, we examined the relationship between single nucleotide polymorphisms (SNPs) in PRL and PRLR, serum prolactin levels and breast cancer risk in a population-based case-control study.
Methods: We genotyped 8 PRL and 20 PRLR tag SNPs in 1965 breast cancer cases and 2229 matched controls, aged 20-74, and living in Warsaw or Lodz, Poland. Serum prolactin levels were measured by immunoassay in a subset of 773 controls. Odds ratios (ORs) and 95% confidence intervals (CIs) for genotype associations with breast cancer risk were estimated using unconditional logistic regression, adjusted for age and study site. Geometric mean prolactin levels were estimated using linear regression models adjusted for age, study site, blood collection time, and menstrual cycle day (premenopausal women).
Results: Three SNPs were associated with breast cancer risk: in premenopausal women, PRLR rs249537 (T vs. C per allele OR 1.39, 95% CI 1.07 - 1.80, P = 0.01); and in postmenopausal women, PRLR rs7718468 (C vs. T per-allele OR 1.16, 95% CI 1.03 - 1.30, P = 0.01) and PRLR rs13436213 (A vs. G per-allele OR 1.13 95% CI 1.01 - 1.26, P = 0.04). However, mean serum prolactin levels for these SNPs did not vary by genotype (P-trend > 0.05). Other SNPs were associated with serum prolactin levels: PRLR rs62355518 (P-trend = 0.01), PRLR rs10941235 (P-trend = 0.01), PRLR rs1610218 (P-trend = 0.01), PRLR rs34024951 (P-trend = 0.02), and PRLR rs9292575 (P-trend = 0.03) in premenopausal controls and PRL rs849872 (P-trend = 0.01) in postmenopausal controls.
Conclusions: Our data provide limited support for an association between common variations in PRLR and breast cancer risk. Altered serum prolactin levels were not associated with breast cancer risk-associated variants, suggesting that common genetic variation is not a strong predictor of prolactin-associated breast cancer risk in this population.

TI The non-protein coding breast cancer susceptibility locus Mcs5a acts in
a non-mammary cell-autonomous fashion through the immune system and
modulates T-cell homeostasis and functions

AB Introduction: Mechanisms underlying low-penetrance, common, non-protein coding variants in breast cancer risk loci are largely undefined. We showed previously that the non-protein coding mammary carcinoma susceptibility locus Mcs5a/MCS5A modulates breast cancer risk in rats and women. The Mcs5a allele from the Wistar-Kyoto (WKy) rat strain consists of two genetically interacting elements that have to be present on the same chromosome to confer mammary carcinoma resistance. We also found that the two interacting elements of the resistant allele are required for the downregulation of transcript levels of the Fbxo10 gene specifically in T-cells. Here we describe mechanisms through which Mcs5a may reduce mammary carcinoma susceptibility.
Methods: We performed mammary carcinoma multiplicity studies with three mammary carcinoma-inducing treatments, namely 7,12-dimethylbenz(a) anthracene (DMBA) and N-nitroso-N-methylurea (NMU) carcinogenesis, and mammary ductal infusion of retrovirus expressing the activated HER2/neu oncogene. We used mammary gland and bone marrow transplantation assays to assess the target tissue of Mcs5a activity. We used immunophenotyping assays on well-defined congenic rat lines carrying susceptible and resistant Mcs5a alleles to identify changes in T-cell homeostasis and function associated with resistance.
Results: We show that Mcs5a acts beyond the initial step of mammary epithelial cell transformation, during early cancer progression. We show that Mcs5a controls susceptibility in a non-mammary cell-autonomous manner through the immune system. The resistant Mcs5a allele was found to be associated with an overabundance of gd T-cell receptor (TCR)+ T-cells as well as a CD62L (L-selectin)-high population of all T-cell classes. In contrast to in mammary carcinoma, gdTCR+ T-cells are the predominant T-cell type in the mammary gland and were found to be overabundant in the mammary epithelium of Mcs5a resistant congenic rats. Most of them simultaneously expressed the CD4, CD8, and CD161 alpha markers. In cultured T-cells of Mcs5a resistant congenic rats we found increased mitogen-induced proliferation and production of Th1 cytokines IFNg, IL-2, and Tumor Necrosis Factor (TNF), but not Th2 cytokines IL-4 and IL-6, or Th17 cytokine IL-17 when compared with susceptible control rats.
Conclusions: These data support a hypothesis that Mcs5a displays a non-mammary cell-autonomous mechanism of action to modulate breast cancer risk through the immune system. The resistant Mcs5a allele is associated with alterations in T-cell homeostasis and functions, and overabundance of gamma delta TCR+ T-cells in carcinogen-exposed mammary epithelium.

AB Induction of epithelial-to-mesenchymal transition (EMT) in cancer stem cells (CSCs) can occur as the result of embryonic pathway signaling. Activation of Hedgehog (Hh), Wnt, Notch, or transforming growth factor-beta leads to the upregulation of a group of transcriptional factors that drive EMT. This process leads to the transformation of adhesive, non-mobile, epithelial-like tumor cells into cells with a mobile, invasive phenotype. CSCs and the EMT process are currently being investigated for the role they play in driving metastatic tumor formation in breast cancer. Both are very closely associated with embryonic signaling pathways that stimulate self-renewal properties of CSCs and EMT-inducing transcription factors. Understanding these mechanisms and embryonic signaling pathways may lead to new opportunities for developing therapeutic agents to help prevent metastasis in breast cancer. In this review, we examine embryonic signaling pathways, CSCs, and factors affecting EMT.

AB This analysis addresses risk of breast cancer among women in BRCA-positive families who test negative for the family mutation. We compared the number of prospectively diagnosed breast cancers in 395 mutation-negative women from 28 BRCA1/2-positive families to an age-, race-, and calendar time-specific expected number of breast cancers derived from the SEER 9 Cancer Registry. Study participants contributed a total of 7008.1 person-years of follow-up. The mean age at study entry was 31.3 years; mean follow-up was 17.7 years. Ten women developed breast cancer yielding an observed-to-expected ratio of 0.82 (95% CI 0.39-1.51). Adjustment for possible reduction in breast cancer risk due to oophorectomy by two different methods resulted in O/E ratios in the range of 0.80-0.99. Stratification by degree of relatedness to the nearest mutation carrier did not substantially alter these results, however, women with at least one-first degree relative with breast cancer appeared to have a slightly increased, though not statistically significant, risk of breast cancer (O/E ratio = 1.33, 95% CI 0.41-2.91). Our data suggest that breast cancer risk among mutation-negative women from BRCA1/2 mutation-positive families is similar to that observed in the general population, with a possible slight increase in risk among mutation-negative women with a family history of breast cancer in a first degree relative. Although this is the largest prospective cohort yet assembled to address this important question, the number of breast cancer events is still relatively small.

AB Mistakes in DNA repair can result in sustained damage and genetic instability. We comprehensively evaluated common variants in DNA repair pathway genes for their association with postmenopausal breast cancer risk with and without respect to estrogen receptor (ER) and progesterone receptor (PR) subtypes. In this study of 1,145 prospectively ascertained breast cancer cases and 1,142 matched controls from the Nurses' Health Study Cancer Genetic Markers of Susceptibility project, we evaluated 1,314 common genetic variants in 68 candidate genes. These variants were chosen to represent five DNA repair pathways including base excision repair, nucleotide excision repair, double-strand break repair (homologous recombination and non-homologous end-joining), direct reversal repair, and mismatch repair, along with candidate DNA polymerases, Fanconi Anemia complementation groups, and other genes relevant to DNA damage recognition and response. Main effects, pathway effects, and pair-wise interactions were evaluated using Logistic Regression, and the Admixture Maximum Likelihood (AML) and Kernel Machine tests. Eight linked loci within XRCC4 were associated with susceptibility to PR- breast cancer (main effect p-values corrected for multiple testing at the within-gene level < 0.04). These loci drove the association between the non-homologous end-joining pathway, and PR- breast cancer (AML p-value for the full pathway = 0.002; p-value when the eight loci were removed = 0.86). A Kernel machine test of no linear or quadratic effects, or pairwise interaction, yielded a p-value of 0.85. Common variation alone in DNA repair genes plays at most a small role in determining postmenopausal breast cancer risk among women of European ancestry.

AB Enhancers, silencer and insulators are DNA elements that play central roles in regulation of the genome that are crucial for development and differentiation. In metazoans, these elements are often separated from target genes by distances that can reach 100 Kb. How regulation can be accomplished over long distances has long been intriguing. Current data indicate that although the mechanisms by which these diverse regulatory elements affect gene transcription may vary, an underlying feature is the establishment of close contacts or chromatin loops. With the generalization of this principle, new questions emerge, such as how the close contacts are formed and stabilized and, importantly, how they contribute to the regulation of transcriptional output at target genes. This review will concentrate on examples where a functional role and a mechanistic understanding has been explored for loops formed between genes and their regulatory elements or among the elements themselves.

AB D4-GDI is a key regulator of Rho GTPases that have been implicated in several aspects of breast tumorigenesis. We have previously found that D4-GDI was selectively expressed in breast cancer cell lines over normal mammary epithelial cells [45]. In this study, we investigated the expression level of D4-GDI in breast tumor specimens (n = 165) by immunohistochemistry using a validated antibody that specifically recognizes the full-length D4-GDI protein. D4-GDI was predominantly expressed in the luminal cells of the duct in contrast to the myoepithelial cells of the outer layer. The percentage of D4-GDI positive samples were found to be higher in the early stages of breast cancers followed by a significant decrease in malignant tumors and metastatic lesions when compared to normal breast tissues (p < 0.01). Analysis of matched samples confirmed the lower expression of D4-GDI in malignant tumors than normal adjacent tissues, while there was no further decrease in metastatic lesions. These results suggest that D4-GDI may function as a biphasic regulator of breast cancer progression and metastasis.

AB With the increasing use of individualized medical care (personalized medicine) in treating and managing patients with cancer, the utilization of biomarkers in selecting and tailoring such medical approaches also is increasing and becoming more important. Specifically, many therapies are effective against only a subgroup of a specific type of tumors and exposing patients with different non-responsive subgroups of the same tumor to ineffective therapies, not only exposes these patients needlessly to acute and chronic side effects of the therapy, but also adds to the costs of medical care. For example, the Oncotype Dx test for estrogen receptor positive tumors that are node negative has been used to identify low risk tumors for which surgery alone is an adequate therapy. Biomarkers may be used to aid in multiple aspects of medical care related to cancer, including early detection, diagnosis, risk assessment, as well as in predicting the aggressiveness of cancers (i.e., prognosis) and predicting the therapeutic efficacy of treatments (i.e., prediction). Biomarkers may be also used as surrogate endpoints to aid in evaluating therapies and preventive approaches. Types of biomarkers vary greatly and include histopathologic appearance, stage of the lesion, quantitative morphologic features, size of the lesion, metastatic pattern and extent of metastasis, as well as imaging and molecular features. The types of measurements of biomarkers also vary; for example, molecular features can be measured at the DNA, mRNA or protein levels as well as at regulatory levels (e. g., microRNA). The usefulness of each biomarker is limited by its sensitivity and specificity in fulfilling its role (e. g., in early detection) and the requirements of sensitivity and specificity to accomplish specific tasks are affected by multiple variables. For example, both very high specificity and sensitivity of a test are required to screen a population with a low prevalence of a specific tumor. The goal of this manuscript is to introduce the reader to how biomarkers may be used and the limitations on the uses of biomarkers in translational research.

AB Invasive tumors (cancers or malignant lesions) typically develop in the setting in which there is the presence of putative non-invasive lesions and the development of these non-invasive lesions frequently precedes the development of cancers. For some organs, such as the oral cavity, cervix and skin, the respective putative pre-invasive lesions can be observed over time and documented to progress to invasive lesions. However, for less readily observable lesions, such as those of the prostate, the progression of the pre-invasive lesions, e. g., prostatic intraepithelial neoplasia (PIN) and prostatic proliferative inflammatory atrophy (PIA) to prostatic cancer are more difficult to document. Thus, for most organ systems, specific pre-invasive neoplastic lesions have been proposed based upon the apparent observations of one or more of the following: 1) microinvasive disease developing from a pre-invasive neoplastic lesion, 2) the general association of the pre-invasive lesion with invasive lesions, 3) the subsequent development of invasive lesions following diagnosis of the pre-invasive lesion, 4) correlations of the molecular features of the putative pre-invasive lesion with the matching invasive lesions, and 5) reductions in the rate of cancer following removal of the pre-invasive lesion. When there are mixtures of pre-invasive lesions with actual cancers in the same case, some of the above specific associations are more difficult to make. Several terms have been used to describe pre-invasive lesions, many of which are now less useful as our knowledge of these lesions increases. It is now commonly accepted that these lesions are a features of the spectrum of neoplastic development and most are accepted as "neoplastic lesions" with associated molecular features, even though they may be reversible even if they have mutations in suppressor genes (e. g., p53) or are associated with viral etiologies (e. g., cervical intraepithelial neoplasia). The overall term, "pre-invasive neoplasia", seems to best describe these putative pre-invasive lesions. Thus, terms such as incipient neoplasia should be abandoned. The term "intra-epithelial neoplasia" with an associated grade, which has been developed for pre-invasive neoplastic lesions of the cervix, i.e. cervical intraepithelial neoplasia (CIN), seems to be a terminology that adds consistency across epithelial organs. Thus, adoption of these terms for the additional organ sites of pancreas (PanIN) and prostate (PIN) seems accepted. Less descriptive terms such as the degrees of dysplasia of the oral cavity and bronchopulmonary system and actinic keratosis and Bowen's disease of the skin might be better designated as oral intraepithelial neoplasia (OIN), pulmonary intraepithelial neoplasia (PulIN) and dermal intraepithelial neoplasia (DIN). The etiology of pre-invasive neoplasia is the etiology of the matching cancers. Some obvious initiating factors include exposure to the whole range of ionizing and non-ionizing radiation, tobacco abuse and a broad range of other carcinogens (e. g., benzene). A frequent initiation factor is the setting of long standing continuing damage, inflammation and repair (LOCDIR) which leads to early molecular features associated with neoplasia after about one year. An excellent example of this is ulcerative colitis (UC) in which dysregulation of microsatellite repair enzymes have been documented one year following diagnosis of UC.
While the nomenclature, description, diagnosis and etiology of pre-invasive neoplasia has advanced, approaches to therapy of such lesions have no progressed adequately even though it has been identified that, for example, removal of polyps periodically from the colorectum, DCIS from the breast, and high grade CIN from the cervix, results in a reduction in the development of cancers of the colorectum, breast, and cervix, respectively. With the development of more molecularly targeted therapy with fewer side effects, preventive therapies may be more successfully targeted to pre-invasive neoplastic lesions.

AB It has become increasingly evident that the study of DNA is inadequate to explain many, if not most, aspects of the development and progression of neoplastic lesions from pre-invasive lesions to metastasis. Thus, the term "genetic" can no longer refer to just the study of the genome. Much of the action in genetic research now shifts to the methods by which the pre-mRNA from one gene is processed to yield multiple different proteins, different quantities of the same protein as well as other forms of regulating RNA. Thus, the age of post-transcriptional processing and epigenetic control of the transfer of information from the genome has arrived. The mechanisms of post-transcriptional processing and epigenetic control that must be characterized in greater detail including alternate splicing, regulation of mRNA degradation, RNA regulatory factors including those factors which extensively edit mRNAs, control of translation, and control of protein stability and degradation. This chapter reviews many of the processes that control information from the genome to proteins and how these factors lead from less than 40,000 genes to more than an order of magnitude increase more proteins which actually control the phenotypes of cells - normal or neoplastic. It is usually the products of genes (e. g., mRNA, microRNA and proteins) that are the molecular markers that will control translational research and ultimately, individualized (personal) medical approaches to disease. This chapter emphasizes how the process of neoplasia "hijacks" the normal processes of cellular operations, especially those processes that are important in the normal development of the organisms - including proliferation, cellular death, angiogenesis, cellular mobility and invasion, and immunoregulation to ensure neoplastic development, survival and progression. This chapter reviews the wide range of processes controlling the information that flows from the genome to proteins and emphasizes how molecular steps in pure processes can be used as biomarkers to study prevention, treatment and/or management of diseases.

AB Molecular biomarkers are widely recognized as having tremendous utility in cancer early detection, prediction, and prevention. Huge efforts have been put into searching of various molecular biomarkers for these purposes, yet there are few molecular biomarkers that have been approved by the Food and Drug Administration for clinical use. Discovery of novel molecular biomarkers is still urgently needed to create biological insights into early events of carcinogenesis and to predict the aggressiveness of early cancer. Noncoding RNAs (ncRNAs) are relatively unexplored molecules identified only one decade ago. With research on the basic biology and mechanisms of ncRNAs, they have rapidly been linked to etiology of diseases, particularly cancer. In this chapter, we will summarize ncRNAs, particularly microRNAs (miRNAs), a type of ncRNAs, as a new frontier for the discovery of cancer biomarkers in preneoplastic lesions and their usefulness as markers for the risk assessment, early detection, and diagnosis of cancer.

AB Background: Genome-wide association studies identified novel breast cancer susceptibility variants that could be used to predict breast cancer in asymptomatic women. This review and modeling study aimed to investigate the current and potential predictive performance of genetic risk models.
Methods: Genotypes and disease status were simulated for a population of 10,000 women. Genetic risk models were constructed from polymorphisms from meta-analysis including, in separate scenarios, all polymorphisms or statistically significant polymorphisms only. We additionally investigated the magnitude of the odds ratios (OR) for 1 to 100 hypothetical polymorphisms that would be needed to achieve similar discriminative accuracy as available prediction models [modeled range of area under the receiver operating characteristic curve (AUC) 0.70-0.80].
Results: Of the 96 polymorphisms that had been investigated in meta-analyses, 41 showed significant associations. AUC was 0.68 for the genetic risk model based on all 96 polymorphisms and 0.67 for the 41 significant polymorphisms. Addition of 50 additional variants, each with risk allele frequencies of 0.30, requires per-allele ORs of 1.2 to increase this AUC to 0.70, 1.3 to increase AUC to 0.75, and 1.5 to increase AUC to 0.80. To achieve AUC of 0.80, even 100 additional variants would need per-allele ORs of 1.3 to 1.7, depending on risk allele frequencies.
Conclusion: The predictive ability of genetic risk models in breast cancer has the potential to become comparable to that of current breast cancer risk models.
Impact: Risk prediction based on low susceptibility variants becomes a realistic tool in prevention of nonfamilial breast cancer. Cancer Epidemiol Biomarkers Prev; 20(1); 9-22. (C) 2011 AACR.

AB Background: Genome-wide association studies (GWAS) have identified numerous prostate cancer susceptibility alleles, but these loci have been identified primarily in men of European descent. There is limited information about the role of these loci in men of African descent.
Methods: We identified 7,788 prostate cancer cases and controls with genotype data for 47 GWAS-identified loci.
Results: We identified significant associations for SNP rs10486567 at JAZF1, rs10993994 at MSMB, rs12418451 and rs7931342 at 11q13, and rs5945572 and rs5945619 at NUDT10/11. These associations were in the same direction and of similar magnitude as those reported in men of European descent. Significance was attained at all reported prostate cancer susceptibility regions at chromosome 8q24, including associations reaching genome-wide significance in region 2.
Conclusion: We have validated in men of African descent the associations at some, but not all, prostate cancer susceptibility loci originally identified in European descent populations. This may be due to the heterogeneity in genetic etiology or in the pattern of genetic variation across populations.
Impact: The genetic etiology of prostate cancer in men of African descent differs from that of men of European descent. Cancer Epidemiol Biomarkers Prev; 20(1); 23-32. (C) 2011 AACR.

TI Variations in Chromosomes 9 and 6p21.3 with Risk of Non-Hodgkin Lymphoma
SO CANCER EPIDEMIOLOGY BIOMARKERS & PREVENTION
LA English

POLYMORPHISMS; ASSOCIATION; DNA
AB Background: There is growing evidence linking genetic variations to non-Hodgkin lymphoma (NHL) etiology. To complement ongoing agnostic approaches for identifying susceptibility genes, we evaluated 488 candidate gene regions and their relation to risk for NHL and NHL subtypes.
Methods: We genotyped 6,679 tag single nucleotide polymorphisms (SNPs) in 947 cases and 826 population-based controls from a multicenter U. S. case-control study. Gene-level summary of associations were obtained by computing the minimum P value ("minP test") on the basis of 10,000 permutations. We used logistic regression to evaluate the association between genotypes and haplotypes with NHL. For NHL subtypes, we conducted polytomous multivariate unconditional logistic regression (adjusted for sex, race, age). We calculated P-trends under the codominant model for each SNP.
Results: Fourteen gene regions were associated with NHL (P < 0.01). The most significant SNP associated with NHL maps to the SYK gene (rs2991216, P-trend = 0.00005). The three most significant gene regions were on chromosome 6p21.3 (RING1/RXRB; AIF1; BAT4). Accordingly, SNPs in RING1/RXRB (rs2855429), AIF1 (rs2857597), and BAT4 (rs3115667) were associated with NHL (P-trends <= 0.0002) and both diffuse large B-cell and follicular lymphomas (P-trends < 0.05).
Conclusions: Our results suggest potential importance for SYK on chromosome 9 with NHL etiology. Our results further implicate 6p21.3 gene variants, supporting the need for full characterization of this chromosomal region in relation to lymphomagenesis.
Impact: Gene variants on chromosome 9 may represent a new region of interesting for NHL etiology. The independence of the reported variants in 6p21.3 from implicated variants (TNF/HLA) supports the need to confirm causal variants in this region Cancer Epidemiol Biomarkers Prev; 20(1); 42-9.

AB Background: The purpose of this meta-analysis was to explore the efficacy of exercise as a nonpharmacologic intervention to reduce cancer-related fatigue (CRF) among adult cancer survivors. We also investigated how different components of the exercise prescription (Ex R-x), methodologic considerations, and subject characteristics modulate CRF.
Methods: A systematic search for randomized controlled trials was conducted using words related to cancer, exercise, and fatigue.
Results: In total, 44 studies with 48 interventions qualified, including 3,254 participants of varying cancer types, stages of diagnosis, treatments, and exercise interventions. Cancer survivors in exercise interventions reduced their CRF levels to a greater extent than usual care controls, d(+) = 0.31 (95% CI = 0.22-0.40), an effect that appeared to generalize across several types of cancer. CRF levels improved in direct proportion to the intensity of resistance exercise (beta = 0.60, P = 0.01), a pattern that was stronger in higher quality studies (beta = 0.23, P < 0.05). CRF levels also reduced to a greater extent when interventions were theoretically driven (beta = 0.48, P < 0.001) or cancer survivors were older (beta = 0.24, P = 0.04).
Conclusions: Exercise reduced CRF especially in programs that involved moderate-intensity, resistance exercise among older cancer survivors and that were guided by theory.
Impact: Our results indicate exercise interventions for adult cancer survivors should be multi-dimensional and individualized according to health outcome and cancer type. Cancer Epidemiol Biomarkers Prev; 20(1); 123-33. (C) 2011 AACR.

AB Background: Oral human papillomavirus type-16 (HPV16) infection is a risk factor for oropharyngeal cancer. We examined oral HPV infection among healthy men.
Methods: Oral rinse/gargle specimens and questionnaire data were collected from 1,688 healthy men aged 18 to 74 (median = 31 years), from the United States, Mexico, and Brazil. HPV16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59, and noncarcinogenic HPV types were detected using Roche Linear Array.
Results: Oral HPV DNA was detected in 67 of 1,680 (4.0%, 95% CI = 3.1%-5.0%) beta-globin-positive specimens; carcinogenic HPVs were detected in 1.3% (95% CI = 0.8%-2.0%; n = 22) and HPV16 was the most commonly detected carcinogenic HPV type (0.6%, 95% CI = 0.2%-1.1%; n = 10). The prevalence of oral HPV infection was similar by country except for HPV55, which had notably higher prevalence in Mexico (3.0%) than Brazil (0%) or the United States (0.2%). Oral HPV prevalence nonsignificantly increased over increasing age categories (P(trend) = 0.096). The strongest predictor of oral HPV was current tobacco use, which increased the odds 2.5-fold (95% CI = 1.4-4.4). Oral sexual behaviors were not associated with oral HPV infection.
Conclusions: Oral HPV16 infection was rare in healthy men, especially at younger ages, and was positively associated with current tobacco use.
Impact: Oral HPV appears to be about 10-fold less prevalent than infection at genital sites in men (4% vs. similar to 40%, respectively). It remains unclear whether this reflects reduced exposure or if the oral region is more resistant to HPV infection compared with anogenital sites. Cancer Epidemiol Biomarkers Prev; 20(1); 172-82.

AB The risk-benefit ratio for concurrent use of dietary antioxidants with chemotherapy or radiation therapy is a controversial topic. In this review, the medical literature on concurrent antioxidant use with chemotherapy or radiotherapy was assessed and further steps for generating evidence-based guidelines are suggested. The clinical cancer research community should cooperate and focus new studies on the use of a specific combination of antioxidant and chemotherapy or radiotherapy, and determine optimal doses for a specific cancer setting. Mechanistic studies on the interaction between antioxidants and conventional cancer therapy could lead to novel biomarkers for assessing dose adequacy.

AB Screening CT identifies small peripheral lung nodules, some of which may be pre- or early invasive neoplasia. Secondary end point analysis of a previous chemoprevention trial in individuals with bronchial dysplasia showed reduction in size of peripheral nodules by inhaled budesonide. We performed a randomized, double-blind, placebo-controlled phase IIb trial of inhaled budesonide in current and former smokers with CT-detected lung nodules that were persistent for at least 1 year. A total of 202 individuals received inhaled budesonide, 800 mu g twice daily or placebo for 1 year. The primary endpoint was the effect of treatment on target nodule size in a per person analysis after 1 year. The per person analysis showed no significant difference between the budesonide and placebo arms (response rate 2% and 1%, respectively). Although the per lesion analysis revealed a significant effect of budesonide on regression of existing target nodules (P = 0.02), the appearance of new lesions was similar in both groups and thus the significance was lost in the analysis of all lesions. The evaluation by nodule type revealed a nonsignificant trend toward regression of nonsolid and partially solid lesions after budesonide treatment. Budesonide was well tolerated, with no unexpected side effects identified. Treatment with inhaled budesonide for 1 year did not significantly affect peripheral lung nodule size. There was a trend toward regression of nonsolid and partially solid nodules after budesonide treatment. Because a subset of these nodules is more likely to represent precursors of adenocarcinoma, additional follow-up is needed. Cancer Prev Res; 4(1); 34-42. (C) 2010 AACR.

AB Resveratrol, a dietary phytoalexin readily available in the diet, is reported to possess antitumorigenic properties in several cancers, including colorectal. However, the underlying mechanism(s) involved is not completely understood. In the present study, we investigated the effect of resveratrol treatment on gene modulation in human colorectal cancer cells and identified activating transcription factor 3 (ATF3) as the most highly induced gene after treatment. We confirmed that resveratrol upregulates ATF3 expression, both at the mRNA and protein level, and showed resveratrol involvement in ATF3 transcriptional regulation. Analysis of the ATF3 promoter revealed the importance of early growth response-1 (Egr-1; located at -245 to -236) and Kruppel-like factor 4 (KLF4; located at -178 to -174) putative binding sites in resveratrol-mediated ATF3 transactivation. Specificity of these sites to the Egr-1 and KLF4 protein was confirmed by electrophoretic mobility shift and chromatin immunoprecipitation assays. Resveratrol increased Egr-1 and KLF4 expression, which preceded ATF3 expression, and further suggests Egr-1 and KLF4 involvement in resveratrol-mediated activity. We provide evidence for Egr-1 and KLF4 interaction in the presence of resveratrol, which may facilitate ATF3 transcriptional regulation by this compound. Furthermore, we demonstrate that induction of apoptosis by resveratrol is mediated, in part, by increased ATF3 expression. Taken together, these results provide a novel mechanism by which resveratrol induces ATF3 expression and represent an additional explanation of how resveratrol exerts its antitumorigenic effects in human colorectal cancer cells.

AB The antitumor effects of nonsteroidal anti-inflammatory drugs (NSAID) are assumed to be due to the inhibition of COX activity, but COX-independent mechanisms may also play an important role. NSAID-activated gene (NAG-1/GDF15) is induced by NSAIDs and has antitumorigenic activities. To determine the contribution of COX-2 inhibition and NAG-1/GDF15 expression to the prevention of colon carcinogenesis by NSAIDs, we evaluated several sulindac derivatives [des-methyl (DM)-sulindac sulfide and its prodrug DM-sulindac] that do not inhibit COX-2 activity. Sulindac sulfide and DM-sulindac induced the expression of NAG-1/GDF15 in HCT116 cells as determined by quantitative real-time PCR and Western blot. We fed APC/Min mice with 320 ppm of sulindac and doses of DM-sulindac. Only sulindac significantly inhibited tumor formation in APC/Min mice. To determine the pharmacokinetic properties of sulindac and DM-sulindac in vivo, wild-type C57/B6 mice were fed with sulindac and DM-sulindac at 80, 160, and 320 ppm. High-performance liquid chromatography analysis revealed that the conversion of DM-sulindac to DM-sulindac sulfide (active form) was less efficient than the conversion of sulindac to sulindac sulfide (active form) in the mice. Lower levels of DM-sulindac sulfide accumulated in intestinal and colon tissues in comparison with sulindac sulfide. In addition, NAG-1/GDF15 was induced in the liver of sulindac-fed mice but not in the DM-sulindac-fed mice. Collectively, our results suggest that the tumor-inhibitory effects of sulindac in APC/Min mice may be due to, in part, NAG-1/GDF15 induction in the liver. Our study also suggests that pharmacologic properties should be carefully evaluated when developing drug candidates. Cancer Prev Res; 4(1); 150-60. (C) 2011 AACR.

AB Clear cell renal cell carcinoma (CCRCC) evolves due to mutations in the Von Hippel-Lindau (VHL) tumor suppressor gene. Although the loss of VHL enables survival and proliferation of CCRCC cells, it is also expected to introduce vulnerabilities that may be exploited for therapeutics discovery. To this end, we developed a high-throughput screen to identify small molecules derived from plants, microorganisms, and marine organisms to which CCRCC cells are sensitive. Screening over 8,000 compounds using this approach, we report here the identification of the microbially derived compound carminomycin I (CA) as an effective inhibitor of VHL-defective (VHL(-/-)) CCRCC cell proliferation. CA also induced apoptosis in CCRCC cells by a mechanism independent of p53 or hypoxia-inducible factor 2. We found that P-glycoprotein (P-gp) sequestered CA within the Golgi complex. Interestingly, Golgi sequestration was critical for the antiproliferative effects of CA and P-gp inhibitors abrogated this activity. Furthermore, CA induced cleavage of the Golgi protein p115 and the translocation of its C-terminal fragment to the nucleus. Finally, examination of the activity of the VHL-interacting Golgi protein, endoplasmic reticulum-Golgi intermediate compartment, ERGIC-53 showed that VHL could mediate protection from CA in CCRCC cells. Our natural product-based screening approach has revealed the P-gp-mediated localization of anticancer compounds within the Golgi in CCRCC cells as a potential strategy of targeting VHL-deficient CCRCC cells.

AB Malignant melanoma is a significant health problem worldwide. Disease relapse due to the heterogeneity and instability of cancer cells may explain the persistence of disease in spite of primary response to therapy. Recent progress in cancer research suggests that melanomas, similar to other solid tumors, contain a subpopulation of cells which have unlimited self-renewal capability directly descending from the original founder cell and characterized by relatively stable genetic properties throughout disease evolution. This model also applies to the development of metastasis and may be responsible for drug resistance and cancer recurrence. These cells with tumor-initiating ability are termed cancer stem cells (CSCs). CSCs as well as tumor cells interact with their microenvironment (niche) to modulate the malignant phenotype. This chapter provides an overview of melanoma stem cell characterization and the interactions between melanoma stem cells and their niche.

AB Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and typically portends a poor prognosis with a median survival ranging from 6 to 16 months. In the United States, a total of 24,120 new cases of primary liver cancers and 18,910 deaths are projected to occur in 2010. Associated factors potentially contributing to this abysmal prognosis include delayed diagnosis, underlying cirrhosis, and resistance to chemotherapy. Recently, compelling evidence has emerged in support of the cancer stem cell (CSC) hypothesis for many solid organ cancers including hepatocellular cancer (HCC). CSCs are postulated to account for tumor initiation, therapeutic resistance, and relapse following surgery or therapy. Identification, proper characterization, and understanding the biology of the HCC-derived CSCs (HCSCs) are imperative for improving early detection and treatment outcomes. If proven correct, the CSC hypothesis may herald a paradigm shift in the treatment of this deadly disease. This chapter summarizes the differences between HCSCs and normal liver stem cells through state-of-the-art identification and characterization, and then assesses the clinical correlation and potential novel therapeutic strategies based on HCSCs.

AB Biliary tract cancers are rare but fatal malignancies, with increasing incidence in Shanghai, China. Gallstones, the primary risk factor for biliary tract cancer, typically result from oversaturation of cholesterol in bile. We examined the association of five variants in three lipid metabolism-related genes (CETP, ABCG8 and LRPAP1) and biliary tract cancers and stones in a population-based case-control study in Shanghai, China. We included 439 biliary tract cancer cases (253 gallbladder, 133 extrahepatic bile duct and 53 ampulla of Vater cancer cases), 429 biliary stone cases and 447 population controls. Carriers of the CG genotype of ABCG8 rs11887534 had higher risk of biliary stones [odds ratio (OR) = 2.3, 95% confidence interval (CI) 0.82-6.5), gallbladder cancer (OR = 4.3, 95% CI 1.7-10.4) and bile duct cancer (OR = 1.94, 95% CI 0.64-5.91), compared with carriers of the GG genotype. Analysis stratified by gender showed both male and female carriers of CG rs11887534 had higher risks of biliary stones and gallbladder cancer, although the association was statistically significant only for women and gallbladder cancer (OR = 6.3, 95% CI 1.86-22.3). Carriers of the ABCG8 haplotype C-C (rs4148217-rs11887534) had a 4.16-fold (95% CI 1.71-10.1) risk of gallbladder cancer compared with those carrying the C-G haplotype. Our findings suggest that ABCG8 rs11887534, identified as a gallstone risk single-nucleotide polymorphism by whole genome scan, is also associated with an increased risk of biliary tract cancer.

AB Mutagen challenge and DNA repair assays have been used in case-control studies for nearly three decades to assess human cancer risk. The findings still engender controversy because blood was drawn after cancer diagnosis so the results may be biased, a type called 'reverse causation'. We therefore used Epstein-Barr virus-transformed lymphoblastoid cell lines established from prospectively collected peripheral blood samples to evaluate lung cancer risk in relation to three DNA repair assays: alkaline Comet assay, host cell reactivation (HCR) assay with the mutagen benzo[a]pyrene diol epoxide and the bleomycin mutagen sensitivity assay. Cases (n = 117) were diagnosed with lung cancer between 0.3 and 6 years after blood collection and controls (n = 117) were frequency matched on calendar year and age at blood collection, gender and smoking history; all races were included. Case and control status was unknown to laboratory investigators. In unconditional logistic regression analyses, statistically significantly increased lung cancer odds ratios (OR(adjusted)) were observed for bleomycin mutagen sensitivity as quartiles of chromatid breaks/cell [relative to the lowest quartile, OR = 1.2, 95% confidence interval (CI): 0.5-2.5; OR = 1.4,95% CI: 0.7-3.1; OR = 2.1,95% CI: 1.0-4.4, respectively, P(trend) = 0.04]. The magnitude of the association between the bleomycin assay and lung cancer risk was modest compared with those reported in previous lung cancer studies but was strengthened when we included only incident cases diagnosed more than a year after blood collection (P(trend) = 0.02), supporting the notion the assay may be a measure of cancer susceptibility. The Comet and HCR assays were unrelated to lung cancer risk.

ID CLINICAL-TRIALS; HYPERTENSION
AB Objective: It was the aim of this study to document the risks of symptomatic patients with angina in placebo-controlled, anti-anginal drug development trials in which symptom-limited exercise testing was used as the primary endpoint. Patients and Methods: The original case report forms submitted to the United States Food and Drug Administration in support of approval of new or supplemental new drug applications between 1973 and 2001 were identified and subjected to a by-patient meta-analysis, utilizing both a maximum likelihood analysis and classical Mantel-Haenszel methods. Results: There were 63 placebo-controlled, clinical trials that randomized 10,865 patients, with 1,047 patient-years of observation time. The trials involved 21 different chemical entities from 4 different drug classes. The relative risk (RR) for withdrawal (placebo compared to drug-treated patients) was not increased [RR = 0.92, 95% confidence interval (CI) 0.78-1.08; p = 0.28]. Of interest, a RR of 0.54 (95% CI 0.26-1.04; p < 0.068) for irreversible harm (a combination of cerebrovascular accidents, myocardial infarction and death) and a RR of 0.89 (95% CI 0.61-1.30; p = 0.56) for serious cardiovascular events (myocardial infarction, congestive heart failure, cerebrovascular accidents) both non-statistically significantly favored being randomized to placebo. Conclusions:For the development of current or future drugs for the treatment of angina, there is no obvious contraindication to the use of placebo controls and exercise tolerance testing.

AB Aims Glucagon-like peptide 1 (GLP-1) is an incretin hormone released from the gut in response to food intake. Whereas GLP-1 acts in the periphery to inhibit glucagon secretion and stimulate insulin release, it also acts in the central nervous system to mediate autonomic control of feeding, body temperature, and cardiovascular function. Because of its role as an incretin hormone, GLP-1 receptor analogs are used as a treatment for type 2 diabetes. Central or peripheral administration of GLP-1 increases blood pressure and heart rate, possibly by activating brainstem autonomic nuclei and increasing vagus nerve activity. However, the mechanism(s) by which GLP-1 receptor stimulation affects cardiovascular function are unknown. We used the long-lasting GLP-1 receptor agonist Exendin-4 (Ex-4) to test the hypothesis that GLP-1 signalling modulates central parasympathetic control of heart rate.
Methods and results Using a telemetry system, we assessed heart rate in mice during central Ex-4 administration. Heart rate was increased by both acute and chronic central Ex-4 administration. Spectral analysis indicated that the high frequency and low frequency powers of heart rate variability were diminished by Ex-4 treatment. Finally, Ex-4 decreased both excitatory glutamatergic and inhibitory glycinergic neurotransmission to preganglionic parasympathetic cardiac vagal neurons.
Conclusion These data suggest that central GLP-1 receptor stimulation diminishes parasympathetic modulation of the heart thereby increasing heart rate.

AB Longitudinal bone growth is rapid in prenatal and early postnatal life, but then slows with age and eventually ceases. This growth deceleration is caused primarily by a decrease in chondrocyte proliferation, and is associated with other structural, functional, and molecular changes collectively termed growth plate senescence. Current evidence suggests that growth plate senescence occurs because the progenitor chondrocytes in the resting zone have a limited replicative capacity which is gradually exhausted with increasing cell division. In addition, recent experimental findings from laboratory and clinical studies suggest that growth plate senescence explains the phenomenon of catch-up growth. Growth-inhibiting conditions such as glucocorticoid excess and hypothyroidism delay the program of growth plate senescence. Consequently, growth plates are less senescent after these conditions resolve and therefore grow more rapidly than is normal for age, resulting in catch-up growth. Copyright (C) 2011 S.

AB The maturation of vertebrate oocyte into haploid gamete, the egg, consists of two specialized asymmetric cell divisions with no intervening S-phase. Ran GTPase has an essential role in relaying the active role of chromosomes in their own segregation by the meiotic process. In addition to its conserved role as a key regulator of macromolecular transport between nucleus and cytoplasm, Ran has important functions during cell division, including in mitotic spindle assembly and in the assembly of nuclear envelope at the exit from mitosis. The cellular functions of Ran are mediated by RanGTP interactions with nuclear transport receptors (NTRs) related to importin beta and depend on the existence of chromosome-centered RanGTP gradient. Live imaging with FRET biosensors indeed revealed the existence of RanGTP gradient throughout mouse oocyte maturation. NTR-dependent transport of cell cycle regulators including cyclin B1, Wee2, and Cdc25B between the oocyte cytoplasm and germinal vesicle (GV) is required for normal resumption of meiosis. After GVBD in mouse oocytes, RanGTP gradient is required for timely meiosis I (MI) spindle assembly and provides long-range signal directing egg cortex differentiation. However, RanGTP gradient is not required for MI spindle migration and may be dispensable for MI spindle function in chromosome segregation. In contrast, MII spindle assembly and function in maturing mouse and Xenopus laevis eggs depend on RanGTP gradient, similar to X. laevis MII-derived egg extracts.

AB Cell migration on two-dimensional (21)) substrates follows entirely different rules than cell migration in three-dimensional (3D) environments. This is especially relevant for leukocytes that are able to migrate in the absence of adhesion receptors within the confined geometry of artificial 313 extracellular matrix scaffolds and within the interstitial space in vivo. Here, we describe in detail a simple and economical protocol to visualize dendritic cell migration in 3D collagen scaffolds along chemotactic gradients. This method can be adapted to other cell types and may serve as a physiologically relevant paradigm for the directed locomotion of most amoeboid cells.

AB NF-kappa B proteins are a family of transcription factors that are of central importance in inflammation and immunity. NF-kappa B also plays important roles in other processes, including development, cell growth and survival, and proliferation, and is involved in many pathological conditions. Reactive Oxygen Species (ROS) are created by a variety of cellular processes as part of cellular signaling events. While certain NF-kappa B-regulated genes play a major role in regulating the amount of ROS in the cell, ROS have various inhibitory or stimulatory roles in NF-kappa B signaling. Here we review the regulation of ROS levels by NF-kappa B targets and various ways in which ROS have been proposed to impact NF-kappa B signaling pathways.

AB A key limiting factor impacting the success of cell transplantation for Parkinson's disease is the survival of the grafted cells, which are often short lived. The focus of this study was to examine a novel strategy to optimize the survival of exogenous fetal ventromesencephalic (VM) grafts by treatment with the p53 inhibitor, pifithrin-alpha (PFT-alpha), to improve the biological outcome of parkinsonian animals. Adult male Sprague-Dawley rats were given 6-hydroxydopamine into the left medial forebrain bundle to induce a hemiparkinsonian state. At 7 weeks after lesioning, animals were grafted with fetal VM or cortical tissue into the lesioned striatum and, thereafter, received daily PFT-alpha or vehicle injections for 5 days. Apomorphine-induced rotational behavior was examined at 2, 6, 9, and 12 weeks after grafting. Analysis of TUNEL or tyrosine hydroxylase (TH) immunostaining was undertaken at 5 days or 4 months after grafting. The transplantation of fetal VM tissue into the lesioned striatum reduced rotational behavior. A further reduction in rotation was apparent in animals receiving PET-alpha and VM transplants. By contrast, no significant reduction in rotation was evident in animals receiving cortical grafts or cortical grafts + PET-alpha. PET-alpha treatment reduced TUNEL labeling and increased TH(+) cell and fiber density in the VM transplants. In conclusion, our data indicate that early postgrafting treatment with PET-alpha enhances the survival of dopamine cell transplants and augments behavioral recovery in parkinsonian animals.

AB Since first being proposed as a tandem gene family in 2001, the relatedness of the 5 SIBLING proteins (BSP, DMP1, DSPP, MEPE, and SPP1/OPN) has predominantly depended on arguments involving shared intron/exon properties as well as conserved protein biochemical properties (e.g. unstructured and acidic) and specific peptide motifs (e.g. phosphorylation and integrin-binding RGD). This report discusses the evidence that an ancient DMP1 gene underwent a simple duplication in the common ancestor of mammals and reptiles and then separately evolved into DSPP-like paralogs in the 2 classes. Genomic sequence analyses show that different copies of the original DMP1 duplication process were selected by mammalian and reptilian (anole lizard) classes to acquire genetically different but biochemically similar phos-phoserine-rich repeat domains by convergent evolution. Mammals, for example, expanded phosphoserine motifs encoded exclusively using motifs containing AGC/T serine codons while the reptile line's repeats also used TCN-encoding serine codons. A similar analysis of the origins of the other 4 SIBLINGs will require even more detailed analysis as genome sequences of various fish and amphibia become available. Copyright (C) 2011 S.

AB Fibromodulin (Fmod) is a keratan sulfate small leucine-rich proteoglycan which is enriched in bones and teeth. In order to determine its functions on bone and tooth mineralization we characterized the phenotype of Fmod-deficient (Fmod-KO) mice using a new-generation microfocus computerized tomography system (micro-CT) and software allowing advanced visualization of 3-D data. Three-week-old and 10-week-old Fmod-KO mandibles and teeth were compared with those of age-matched wild-type (WT) mice. In both young and mature mice the Fmod-KO mandibles were hypomineralized, especially the posterior (proximal) part of the mandible as it appeared to be the main target of the molecule deficiency whereas less extensive alterations were found in the alveolar bone. In transverse sections, larger marrow spaces were observed in the Fmod-KO mice compared with age-matched young or mature WT mice. Quantitative evaluation of the pulp volume of the first molar and 3-D reconstructions suggested that dentinogenesis was diminished in 3-week-old Fmod-KO teeth. In contrast, increased dentin formation was found in 10-week-old Fmod-KO mice and it was accompanied by a reduced pulp volume. Thus, the differential effects of Fmod deficiency on bones and teeth appear to diverge in adult mice. This may result from the previously reported differences in the molecular weight of Fmod in the 2 tissues or from compensatory mechanisms due to the overexpression of DSP and DMP-1 in the dental pulp of Fmod-KO. It is also possible that a single molecule plays diverging roles in a tissue-specific or region-specific manner. Copyright (C) 2011 S. Karger AG, Basel

AB Amelogenesis imperfecta (AI) represents hereditary conditions affecting the quality and quantity of enamel. Six genes are known to cause AI (AMELX, ENAM, MMP20, KLK4, FAM83H, and WDR72). Our aim was to determine the distribution of different gene mutations in a large AI population and evaluate phenotype-genotype relationships. Affected and unaffected family members were evaluated clinically and radiographically by one examiner. Genotyping was completed using genomic DNA obtained from blood or saliva. A total of 494 individuals were enrolled, with 430 (224 affected, 202 unaffected, and 4 not definitive) belonging to 71 families with conditions consistent with the diagnosis of AI. Diverse clinical phenotypes were observed (i.e. hypoplastic, hypocalcified, and hypomaturation). Genotyping revealed mutations in all 6 candidate genes. A molecular diagnosis was made in 132 affected individuals (59%) and in 26 of the families (37%). Mutations involved 12 families with FAM83H (46%), 6 families with AMELX (23%), 3 families with ENAM (11%), 2 families with KLK4 and MMP20 (8% for each gene), and 1 family with a WDR72 mutation (4%). Phenotypic variants were associated with allelic FAM83H and AMELX mutations. Two seemingly unrelated families had the same KLK4 mutation. Families affected with AI where candidate gene mutations were not identified could have mutations not identifiable by traditional gene sequencing (e.g. exon deletion) or they could have promoter sequence mutations not evaluated in this study. However, the results suggest that there remain new AI causative genes to be identified. Copyright (C) 2011 S. Karger AG, Basel

AB 4'-Ethynyl-2-fluoro-2'-deoxyadenosine (EFdA) is the most potent inhibitor of HIV reverse transcriptase (RT). We have recently named EFdA a Translocation Defective RT Inhibitor (TDRTI) because after its incorporation in the nucleic acid it blocks DNA polymerization, primarily by preventing translocation of RT on the template/primer that has EFdA at the 3'-primer end (T/P-EFdA). The sugar ring conformation of EFdA may also influence RT inhibition by a) affecting the binding of EFdA triphosphate (EFdATP) at the RT active site and/or b) by preventing proper positioning of the 3'-OH of EFdA in T/P-EFdA that is required for efficient DNA synthesis. Specifically, the North (C2'-exo/C3'-endo), but not the South (C2'-endo/C3'-exo) nucleotide sugar ring conformation is required for efficient binding at the primer-binding and polymerase active sites of RT. In this study we use nuclear magnetic resonance (NMR) spectroscopy experiments to determine the sugar ring conformation of EFdA. We find that unlike adenosine nucleosides unsubstituted at the 4'-position, the sugar ring of EFdA is primarily in the North conformation. This difference in sugar ring puckering likely contributes to the more efficient incorporation of EFdATP by RT than dATP. In addition, it suggests that the 3'-OH of EFdA in T/P-EFdA is not likely to prevent incorporation of additional nucleotides and thus it does not contribute to the mechanism of RT inhibition. This study provides the first insights into how structural attributes of EFdA affect its antiviral potency through interactions with its RT target.

AB The thyrotropin receptor (TSHR) exhibits elevated cAMP signaling in the basal state and becomes fully activated by thyrotropin. Previously we presented evidence that small-molecule ligands act allosterically within the transmembrane region in contrast to the orthosteric extracellular hormone-binding sites. Our goal in this study was to identify positions that surround the allosteric pocket and that are sensitive for inactivation of TSHR. Homology modeling combined with site-directed mutagenesis and functional characterization revealed seven mutants located in the allosteric binding site that led to a decrease of basal cAMP signaling activity. The majority of these silencing mutations, which constrain the TSHR in an inactive conformation, are found in two clusters when mapped onto the 3D structural model. We suggest that the amino acid positions identified herein are indicating locations where small-molecule antagonists, both neutral antagonists and inverse agonists, might interfere with active TSHR conformations.

AB DNA polymerase gamma (pol gamma), encoded by POLG, is responsible for replicating human mitochondrial DNA. About 150 mutations in the human POLG have been identified in patients with mitochondrial diseases such as Alpers syndrome, progressive external ophthalmoplegia, and ataxia-neuropathy syndromes. Because many of the mutations are described in single citations with no genotypic family history, it is important to ascertain which mutations cause or contribute to mitochondrial disease. The vast majority of data about POLG mutations has been generated from biochemical characterizations of recombinant pol gamma. However, recently, the study of mitochondrial dysfunction in Saccharomyces cerevisiae and mouse models provides important in vivo evidence for the role of POLG mutations in disease. Also, the published 3D-structure of the human pol gamma assists in explaining some of the biochemical and genetic properties of the mutants. This review summarizes the current evidence that identifies and explains disease-causing POLG mutations.

AB This chapter presents and discusses evidence of possible mechanistic involvement of oxidative DNA and protein damage in metal-induced carcinogenesis. Carcinogenic metals, e.g., Be, Cd, Cr, Co, Ni, and the metalloid As, are capable of generating various kinds of active oxygen and other reactive species in direct redox reactions with O-2, O-2(-center dot), H2O2, organic peroxides, and other cellular or tissue substrates, and/or indirectly by inducing inflammation or unleashing physiological redox-active metals, Fe and Cu. The reactive species may damage all cell components, including DNA, RNA, free triphosphonucleosides, proteins, and lipids, and exhaust cellular antioxidant defenses, e.g., deplete ascorbate. The damage may be aggravated by metal-assisted inhibition of DNA repair and histone demethylation systems. The association of oxidative damage with carcinogenesis is strongly supported by mutagenicity of DNA base products, strand breaks, apurinic sites, cross-links, and adducts typical for the attacking reactive species (oxygen-, carbon-, or sulfur-centered radicals), originating from oxidized amino acids and proteins, and 4-hydroxynonenal, a lipid oxidation product. Oxidative damage to nuclear proteins affects chromatin structure and gene expression, whereas such damage to regulatory proteins disturbs cell cycle and apoptosis. Thus, oxidative DNA damage may assist in the initiation while RNA and protein damage may facilitate the promotion and progression of cancer.

AB Th1 cells are remarkably more susceptible to activation induced cell death than Th17. Here, we compared cultures of these two cell subpopulations for their expression of apoptosis-related molecules when re-exposed to their specific antigen. We also compared the expression of apoptosis-related molecules in the mouse eye with inflammation induced by Th1 or Th17 cells. Using qPCR we found that the mRNA transcript levels of the majority of tested apoptosis-related molecules were higher in the Th1 cultures, and in eyes with Th1-induced inflammation. Apoptotic intrinsic pathway molecules played minor roles in the processes in vitro or in vivo, whereas extrinsic pathway molecules, as well as PD-1, its ligands and Tim3, were heavily involved.

AB Here we imaged the exocytosis of lytic granules from human CD8(+) cytotoxic T lymphocytes using rapid total internal reflection microscopy, Lamp-1 tagged with mGFP to follow the fate of the lytic granule membrane, and granzyme A, granzyme B or serglycin tagged with mRFP to follow the fate of lytic granule cargo. Lytic granules were released by full fusion with the plasma membrane, such that the entire granule content for all three cargos visualized was released on a subsecond time scale. The behavior of GFP-Lamp-1 was, however, more complex. While it entered the plasma membrane in all cases, the extent to which it then diffused away from the site of exocytosis varied from nearly complete to highly restricted. Finally, the diffusion properties upon release of the three cargos examined put an upper limit on the size of the macromolecular complex of granzyme and serglycin that is presented to the target cell.

AB Here, we analyze for the first time the immunological and therapeutic efficacy of a dendritic cell (DC) vaccine based on a cancer-testis antigen, Brother of regulator of imprinted sites (BORIS), an epigenetically acting tumor-promoting transcription factor. Vaccination of mice with DC loaded with truncated form of BORIS (DC/mBORIS) after 4T1 mammary tumor implantation induced strong anti-cancer immunity, inhibited tumor growth (18.75% of mice remained tumor-free), and dramatically lowered the number of spontaneous clonogenic metastases (50% of mice remained metastases-free). Higher numbers of immune effector CD4 and CD8 T cells infiltrated the tumors of vaccinated mice vs. control animals. Vaccination significantly decreased the number of myeloid-derived suppressor cells (MDSCs) infiltrating the tumor sites, but not MDSCs in the spleens of vaccinated animals. These data suggest that DC-based mBORIS vaccination strategies have significant anti-tumor activity in a therapeutic setting and will be more effective when combined with agents to attenuate tumor-associated immune suppression.

AB Enlargement of the vestibular aqueduct (EVA) is the most common inner ear anomaly detected in ears of children with sensorineural hearing loss. Pendred syndrome (PS) is an autosomal recessive disorder characterized by bilateral sensorineural hearing loss with EVA and an iodine organification defect that can lead to thyroid goiter. Pendred syndrome is caused by mutations of the SLC26A4 gene. SLC26A4 mutations may also be identified in some patients with nonsyndromic EVA (NSEVA). The presence of two mutant alleles of SLC26A4 is correlated with bilateral EVA and Pendred syndrome, whereas unilateral EVA and NSEVA are correlated with one (M1) or zero (M0) mutant alleles of SLC26A4. Thyroid gland enlargement (goiter) appears to be primarily dependent on the presence of two mutant alleles of SLC26A4 in pediatric patients, but not in older patients. In M1 families, EVA may be associated with a second, undetected SLC26A4 mutation or epigenetic modifications. In M0 families, there is probably etiologic heterogeneity that includes causes other than, or in addition to, monogenic inheritance. Copyright (C) 2011 S. Karger AG, Basel

AB The loss of cell volume, termed apoptotic volume decrease (AVD) has been a hallmark feature of apoptosis. However the role of this characteristic attribute of programmed cell death has always been questioned as to whether it plays an active or passive factor during apoptosis. Here we review studies that suggest that AVD plays an active role during apoptosis and the underlying flux of ions that results in this morphological event regulates the programmed cell death process.

AB Background: Post-traumatic stress disorder (PTSD) has been shown to be associated with migraine and drug abuse.
Methods: This was an analysis of data from the National Comorbidity Survey Replication (NCS-R) to evaluate the association of PTSD in those with episodic migraine (EM) and chronic daily headache (CDH).
Results: Our sample consisted of 5,692 participants. Lifetime and 12-month prevalence rates of PTSD were increased in those with EM and CDH. After adjustments, the lifetime odds ratio (OR) of PTSD was greater in those with EM (OR 3.07 confidence interval [CI]: 2.12, 4.46) compared to those without headache; was greater in men than women with EM (men: OR 6.86; CI: 3.11, 15.11; women: OR 2.77; CI: 1.83, 4.21); and was comparable or greater than the association between migraine with depression or anxiety. The lifetime OR of PTSD was also increased in CDH sufferers. The OR of illicit drug abuse was not increased in those with EM or CDH unless co-occurring with PTSD or depression.
Conclusion: The lifetime and 12-month OR of PTSD is increased in those with migraine or CDH, and is greater in men than women with migraine. The lifetime and 12-month OR of illicit drug abuse is not increased in those with migraine or CDH unless co-occurring with PTSD or depression.

We carried out a novel, ecologically valid, virtual-reality experiment using blood oxygen level-dependent functional magnetic resonance imaging (fMRI) where SA could be modulated in real-time while subjects performed voluntary finger movements. Behavioral testing was also performed to assess the explicit judgment of SA. Twenty healthy volunteers completed the experiment. Results of the behavioral testing demonstrated paradigm validity along with the identification of a bias that led subjects to over- or underestimate the amount of control they had. The fMRI experiment identified 2 discrete networks. These leading and lagging networks likely represent a spatial and temporal flow of information, with the leading network serving the role of mismatch detection and the lagging network receiving this information and mediating its elevation to conscious awareness, giving rise to SA.

AB Mechanosensitive TREK channels belong to the family of K2P channels, a family of widely distributed, well-modulated channels that uniquely have two similar or identical subunits, each with two TM1-P-TM2 motifs. Our goal is to build viable structural models of TREK channels, as representatives of K2P channels family. The structures available to be used as templates belong to the 2TM channels superfamily. These have low sequence similarity and different structural features: four symmetrically arranged subunits, each having one TM1-P-TM2 motif. Our model building strategy used two subunits of the template (KcsA) to build one subunit of the target (TREK-1). Our models of the closed channel were adjusted to differ substantially from those of the template, e. g., TM2 of the second repeat is near the axis of the pore whereas TM2 of the first repeat is far from the axis. Segments linking the two repeats and immediately following the last TM segment were modeled ab initio as alpha-helices based on helical periodicities of hydrophobic and hydrophilic residues, highly conserved and poorly conserved residues and statistically related positions from multiple sequence alignments. The models were further refined by 2-fold symmetry-constrained MD simulations using a protocol we developed previously. We also built models of the open state and suggest a possible tension-activated gating mechanism characterized by helical motion with 2-fold symmetry. Our models are consistent with deletion/truncation mutagenesis and thermodynamic analysis of gating described in the accompanying paper.

AB TREK-1, a mechanosensitive K channel from the two-pore family (K(2)P), is involved in protective regulation of the resting potential in CNS neurons and other tissues. The structure of TREK-1 and the basis of its sensitivity to stretch and variety of lipid-soluble factors remain unknown. Using existing K channel structures as modeling templates, TREK-1 was envisioned as a 2-fold symmetrical complex with the gate formed primarily by the centrally positioned TM2b helices of the second homologous repeat. Opening was modeled as a conical expansion of the barrel separating TM2b's accompanied by extension of TM2a helices with the cytoplasmic TM2a-TM1b connector. Seeking first experimental support to the models we have accomplished thermodynamic analysis of mouse TREK-1 gating and functional testing of several deletion mutants. The predicted increase of the channel in-plane area (Delta A) of similar to 5 nm(2) in models was supported by the experimental Delta A of similar to 4 nm(2) derived from the slope of open probability versus membrane tension in HE K-293T cells and their cytoskeleton-depleted blebs. In response to steps of suction, wild-type channel produced transient currents in cell-attached patches and mostly sustained currents upon patch excision. TREK-1 motifs not present in canonical K channels include divergent cytoplasmic N- and C-termini, and a characteristic 50-residue extracellular loop in the first homologous repeat. Deletion of the extracellular loop (Delta 76-124) reduced the average current density in patches, increased spontaneous activity and generated a larger sub-population of high-conductance channels, while activation by tension augmented by arachidonic acid was fully retained. Further deletion of the C-terminal end (Delta 76-124/Delta 334-411) removed voltage dependency but otherwise produced no additional effect. In an attempt to generate a cysteine-free version of the channel, we mutated two remaining cysteines 159 and 219 in the transmembrane region. C219A did not compromise channel activity, whereas the C159A/S mutants were essentially inactive. Treatment with beta-mercaptoethanol suggested that none of these cysteines form functionally-important disulfides.

AB Nanotechnology offers many potential benefits to medical research by making pharmaceuticals more efficacious and by decreasing their adverse side-effects. Preclinical characterization of nanoparticles intended for medical applications is complicated due to the variety of materials used, their unique surface properties and multifunctional nature. This chapter serves as an introduction to the volume, giving a broad overview of applications of nanotechnology to medicine, and describes some of the beneficial aspects of nanotechnology-based drug delivery. We define nanotechnology and provide brief descriptions of the major classes of nanomaterials used for medical applications. The following two chapters discuss scientific and regulatory hurdles involved in the use of nanotechnology in medicine. The remaining bulk of the volume provides the reader with protocols that have been tested against clinically relevant nanoparticles and describes some of the nuances of nanoparticle types and necessary controls.

AB The Food and Drug Administration (FDA) and pharmaceutical industry have used standards to assess material biocompatibility, immunotoxicity, purity, and sterility (as well as many other properties) for several decades. Nanoparticle developers and manufacturers leverage well-established methods as much as possible. However, the unique properties of nanomaterials often interfere with standardized protocols, giving Use-positive or false-negative results. This chapter provides details of some of the problems which can arise during the characterization of nanoparticle samples. Additionally, we discuss ways to identify, avoid, and resolve such interference, with emphasis on the use of inhibition and enhancement controls.

DE Zeta potential; surface charge; nanoparticles
AB This chapter describes a method for the measurement of the electrostatic potential at the electrical double layer surrounding a nanoparticle in solution. This is referred to as the zeta potential. Nanoparticles with a zeta potential between -10 and +10 mV are considered approximately neutral, while nanoparticles with zeta potentials of greater than +30 mV or less than -30 mV are considered strongly cationic and strongly anionic, respectively. Since most cellular membranes are negatively charged, zeta potential can affect a nanoparticle's tendency to permeate membranes, with cationic particles generally displaying more toxicity associated with cell wall disruption. This technique is demonstrated for two types of nanoparticles commonly used in biological applications: colloidal gold (strongly anionic) and amine-terminated PAMAM dendrimer (strongly cationic).

The purpose of this procedure is to preserve the structure of tissue in a hardened epoxy block with minimal disruption of cellular structures, to aid in the meaningful analysis of in vivo or cell culture experiments. The process begins with hydrated tissue and ends with tissue that is virtually water-free and preserved in a static state within a plastic resin matrix. The resin mixture permeates the dehydrated tissue, making the sample firm enough to cut. Procedures are also given for fixing nanoparticle-containing cell culture samples.

AB Energy Dispersive X-ray (EDX) microanalysis is a technique used for identification of the elemental composition of a specimen. The detection of nanoparticles in tissue is a common problem of biodistribution and toxicity studies. High-resolution transmission electron microscopy (TEM) can be employed to detect nanoparticles based on morphology; however, TEM alone cannot conclusively identify nanoparticles. Indeed, micrographs are often ambiguous due to particle aggregation, contamination, or morphology change after cellular uptake. EDX can be used to confirm the composition and distribution of the nanoparticles through spectrum and elemental mapping.
This protocol outlines the procedures for compositional identification of nanoparticles using an EDX spectrometer incorporated into a scanning electron microscopy (SEM) system. This protocol outlines sample preparation, EDX spectrum acquisition, elemental peak analysis and spectral mapping acquisition.

AB This chapter describes a method for the measurement of free gadolinium in nanoparticle samples. Conjugation of a gadolinium-chelate to a nanoparticle allows the particle's distribution to be imaged via magnetic resonance imaging (MRI). Free (unchelated) gadolinium is a known toxin, being a heavy metal, and may contribute towards total gadolinium concentration. Determining the amount of free gadolinium is therefore an important aspect of the preclinical characterization of gadolinium-chelate MRI imaging agent nanoparticles.

ID LIPOPOLYSACCHARIDE
AB Bacterial endotoxin or lipopolysaccharide (LPS) is a membrane component of all Gram-negative bacteria. The administration of products contaminated with bacterial endotoxin can cause fever, shock, and even death. Accordingly, the FDA sets limits on the number of endotoxin units (EU) that may be present in a drug or device product. Limulus amoebocyte lysate (LAL) is the extract from amoebocytes of the horseshoe crab Limulus polyphemus, which reacts with bacterial endotoxin. Detection of the products of this reaction is an effective means of quantifying the EU present in a drug formulation. However, nanoparticles frequently interfere with the reactivity of endotoxin, the LAL reaction, or the detection of the reaction products. This interference can be manifested as either an enhancement or an inhibition, causing a respective overestimation or underestimation of the EU in the sample. Here, we present two methods for the detection and quantification of endotoxin in nanoparticle preparations: one is based on an end-point chromogenic LAL assay, and the second approach is based on measuring the turbidity of the LAL extract.

AB This chapter provides a protocol for quantitative analysis of gold in solution as well as gold uptake by macrophages. A 96-well fluorescence assay was developed to be able to determine gold concentrations for a given gold nanoparticle as well as quantify the degree of gold nanoparticle uptake by macrophages. This assay detects a decrease in the fluorescence of a dye upon forming a complex with gold and a ligand. The decrease in fluorescence is proportional to the amount of gold. This protocol provides a preliminary and qualitative first-step alternative for the determination of gold nanoparticle concentration without requiring expensive, time-consuming methods such as inductively coupled plasma mass spectroscopy. This protocol can be used to support the uptake studies by the light microscopy method described in Chapter 23. This assay requires 200 mu L of each test nanoparticle at a concentration of the users choosing. Up to 32 variations of test nanoparticles can be evaluated in duplicate in one assay run.

The protocol utilizes the fluorescent redox active probe, dichlorofluorescein diacetate (DCFH-DA). Primary hepatocytes were chosen for this assay since they have greater metabolic activity than hepatocyte cell lines. This method extends previous standardized cytotoxicity methods for particulates by evaluating mechanisms of toxicity in potential target organ cells. Oxidative stress has been identified as a likely mechanism of nanoparticle toxicity, and cell-based in vitro systems for evaluation of nanoparticle-induced oxidative stress are widely considered an important component of biocompatibility screens.

Oxidative stress has been identified as a likely mechanism of nanoparticle toxicity, and cell-based in vitro systems for evaluation of nanoparticle-induced oxidative stress are widely considered to be an important component of biocompatibility screens. The products of lipid peroxidation, lipid hydroperoxides, and aldehydes, such as MDA, can be measured via a thiobarbituric acid reactive substances (TBARS) assay. In this assay, which can be performed in cell culture or in cell lysate, MDA combines with thiobarbituric acid (TBA) to form a fluorescent adduct that can be detected at an excitation wavelength of 530 nm and an emission wavelength of 550 nm. The results are then expressed as MDA equivalents, normalized to total cellular protein (determined by Bradford assay).

Glutathione is a tripeptide (L-gamma-glutamyl-L-cysteinyl-glycine) present intracellularly in millimolar concentrations and one of the primary cellular antioxidant defenses against oxidative stress. An increase in the relative amount of oxidized to reduced glutathione may be indicative of oxidative stress, while a decrease in the overall glutathione pool may be indicative of conjugative metabolism or impaired synthesis. The method presented in this chapter utilizes a colorimetric method for detection of reduced and oxidized glutathione.

AB Lysosomal dysfunction is a recognized toxic mechanism for xenobiotics, which can result in various pathological states. There is concern that nanoparticles, in particular, may cause lysosomal pathologies, since they are likely to accumulate within lysosomes. Dysregulation of the autophagy-lysosomal degradation pathway is an example of lysosomal dysfunction associated with exposure to some nanomaterials. Here, we present a method to monitor autophagy by measurement the autophagosome marker LC3-II, a phosphatidylethanolamine (PE)-conjugated form of microtubule-associated protein 1 light chain 3-I (MAP LC3-I). As other conditions could potentially result in LC3-II expression, treatment-related changes in expression should be further evaluated by morphological assessment, using techniques such as electron microscopy, to confirm autophagosome involvement.

AB Certain nanoparticles have been shown to accumulate within lysosome and hence may cause lysosomal pathologies such as phospholipidosis, lysosomal overload, and autophagy. This chapter describes a method for evaluation of lysosomal activity in porcine kidney cells (LLC-PK1) after exposure to nanoparticles. This method uses the accumulation of a cationic fluorescent dye (LysoTracker Red) in acidic cellular compartments as an indicator of total lysosome content. The lysotracker signal is normalized to the signal from a thiol-reactive dye which is proportional to the total number of viable cells.

AB Hemolysis is damage to red blood cells (RBCs), which results in the release of the iron-containing protein hemoglobin into plasma. Here we describe an in vitro assay specifically developed for the analysis of nanoparticle hemolytic properties (see Fig. 1). In this assay, analyte nanoparticles arc incubated in blood, and hemoglobin is released by damaged cells and converted to red-colored cyanmethemoglobin by reagents. The nanoparticles and undamaged RBCs arc then removed by centrifugation, and the amount of cyanmethemoglobin in the supernatant is measured by spectrophotometry. This measured absorbance is compared to a standard curve to determine the concentration of hemoglobin in the supernatant. This hemoglobin concentration is then compared to that in the supernatant of a blood sample treated with a negative control to obtain the percentage of nanoparticle-induced hemolysis.

DE Nanoparticles; thrombogenicity; platelet aggregation; platelet; blood;

AB Thrombus formation is complex process involving both cellular and molecular (protein) components. Platelets are responsible for maintaining hemostasis and for preventing excessive bleeding. These cells aggregate along with other plasma components and blood cells to form blood clots. Undesirable platelet aggregation may lead to life-threatening conditions such as stroke. Thrombogenicity is the property of a material to induce the formation of a thrombus, which results in partial or complete occlusion of a blood vessel. The tendency to cause platelet aggregation and perturb plasma coagulation can serve as an in vitro measure of a nanomaterial's likelihood to be thrombogenic in vivo. This chapter describes a procedure for in vitro analyses of platelet aggregation and plasma coagulation time. Platelet-rich plasma (PRP) is obtained from freshly derived human whole blood and incubated with nanoparticles. Then the plasma is examined using a particle count and size analyzer to determine the number of active platelets. The percent aggregation is calculated by comparing the number of active platelets in the nanoparticle-exposed sample to control plasma. To measure the plasma coagulation time, platelet-poor plasma from human whole blood is exposed to nanoparticles in vitro and analyzed in prothrombin (PT), activated partial thromboplastin (APTT), and thrombin time assays.

AB This chapter describes a method for qualitative detection of complement activation by western blot. This method uses the cleavage product of the C3 component as a marker for complement activation by any pathway. In this protocol, human plasma is exposed to nanoparticles and then analyzed by polyacrylamide gel electrophoresis (PAGE) followed by western blot with anti-C3-specific antibodies. These antibodies recognize both the native C3 component of complement and its cleavage products. The amounts of C3 and the C3 cleavage products are compared to the amounts in control (untreated) plasma and to plasma treated with a positive control to provide a quick and inexpensive qualitative assessment of complement activation.

AB Chemotaxis is the phenomenon in which cells direct their movements in the presence of certain chemicals (chemoattractants or chemorepellents). Leukocyte recruitment (via chemotaxis) is an important component of the inflammatory response, both in physiological host defense and in a range of prevalent disorders that include an inflammatory component. Circulating leukocytes in the bloodstream migrate towards the site of inflammation in response to a complex network of proinflammatory signaling molecules (including cytokines, chemokines and prostaglandins). This chapter describes a method for rapid measure of the chemoattractant capacity of nanoparticulate materials. This method is an in vitro model for chemotaxis, in which promyelocytic leukemia cell migration through a filter is monitored using a fluorescent dye.

As a consequence, much has been published on the design and synthesis of molecular imaging probes focusing on each modality, each type of material, or each target disease. More recently, second generation molecular imaging probes with unique, multi-functional, or multiplexed characteristics have been designed. This critical review focuses on (i) molecular imaging using combinations of modalities and signals that employ the full range of the electromagnetic spectra, (ii) optimized chemical design of molecular imaging probes for in vivo kinetics based on biology and physiology across a range of physical sizes, (iii) practical examples of second generation molecular imaging probes designed to extract complementary data from targets using multiple modalities, color, and comprehensive signals (277 references).

AB In this chapter we discuss the landscape view of structure activity relationships (SARs) The motivation for such a view is that SARs come in a variety of forms, such as those where small changes in structure lead to small changes in activity or where small structural lead to significant changes in activity (also termed activity cliffs) Thus, an SAR dataset is viewed as a landscape comprised of smooth plains, rolling hills, and jagged gorges We review the history of this view and early quantitative approaches that attempted to encode the landscape We then discuss some recent developments that directly characterize structure activity landscapes, in one case with the goal of highlighting activity cliffs while the other allows one to resolve different types of SAR that may be present in a dataset We highlight sonic applications of these approaches, such as predictive model development and SAR elucidation, to SAR datasets obtained from the literature Finally, we conclude with a summary of the landscape approach and why it provides an intuitive and rigorous alternative to standard views of structure activity data

AB Individuals with Autism Spectrum Disorders (ASD) often struggle with complex tasks, such as those requiring divided attention (simultaneously completing two independent tasks) that also place high demands on working memory. Prior research shows that divided attention is impaired in adults and children with ASD and is related to ASD and comorbid attention deficit/hyperactivity disorder (ADHD) symptoms, but the impact on everyday functioning is unclear. Because ADHD symptoms are associated with poor divided attention and working memory performance in children with ASD, we also examined ADHD symptoms as moderators of divided attention performance. We examined performance on the Consonant Trigrams Test (CTT) between high-functioning 8- to 13-year-olds with ASD (n=28) and typically developing controls (n=18) matched on age and IQ. In the ASD group, we also correlated performance with ADHD symptoms and behavior ratings of everyday working memory. CTT performance in children with ASD was significantly worse than in matched controls. A significant correlation between CTT performance and everyday working memory was observed, but CTT performance was not related to comorbid ADHD symptoms in the ASD group. Divided attention with high working-memory demands is a relative weakness in children with high-functioning ASD; this weakness relates to everyday functioning, and it is independent from ADHD symptoms. That ADHD symptoms are not associated with divided attention performance is inconsistent with one prior investigation, which likely results from using different divided attention tasks in the two studies.

AB Addictive drugs have in common that they are voluntarily self-administered by laboratory animals (usually avidly), and that they enhance the functioning of the reward circuitry of the brain (producing the 'high' that the drug user seeks) The core reward circuitry consists of an 'in-series' circuit linking the ventral tegmental area, nucleus accumbens and ventral pallidum via the medial forebrain bundle Although originally believed to simply encode the set point of hedonic tone, these circuits are now believed to be functionally far more complex, also encoding attention, expectancy of reward, disconfirmation of reward expectancy, and incentive motivation. 'Hedonic dysregulation' within these circuits may lead to addiction The 'second-stage' dopaminergic component in this reward circuitry is the crucial addictive-drug-sensitive component All addictive drugs have in common that they enhance (directly or indirectly or even transsynaptically) dopaminergic reward synaptic function in the nucleus accumbens Drug self-administration is regulated by nucleus accumbens dopamine levels, and is done to keep nucleus accumbens dopamine within a specific elevated range (to maintain a desired hedonic level) For some classes of addictive drugs (e g opiates), tolerance to the euphoric effects develops with chronic use. Postuse dysphoria then comes to dominate reward circuit hedonic tone, and addicts no longer use drugs to get high, but simply to get back to normal ('get straight'). The brain circuits mediating the pleasurable effects of addictive drugs are anatomically, neurophysiologically and neurochemically different from those mediating physical dependence, and from those mediating craving and relapse There are important genetic variations in vulnerability to drug addiction, yet environmental factors such as stress and social defeat also alter brain-reward mechanisms in such a manner as to impart vulnerability to addiction In short, the 'bio-psycho-social' model of etiology holds very well for addiction. Addiction appears to correlate with a hypodopaminergic dysfunctional state within the reward circuitry of the brain. Neuroimaging studies in humans add credence to this hypothesis Credible evidence also implicates serotonergic, opioid, endocannabinoid, GABAergic and glutamatergic mechanisms in addiction Critically, drug addiction progresses from occasional recreational use to impulsive use to habitual compulsive use This correlates with a progression from reward-driven to habit-driven drug-seeking behavior. This behavioral progression correlates with a neuroanatomical progression from ventral striatal (nucleus accumbens) to dorsal striatal control over drug-seeking behavior The three classical sets of craving and relapse triggers are (a) reexposure to addictive drugs, (b) stress, and (c) reexposure to environmental cues (people, places, things) previously associated with drug-taking behavior. Drug-triggered relapse involves the nucleus accumbens and the neurotransmitter dopamine. Stress-triggered relapse involves (a) the central nucleus of the amygdala, the bed nucleus of the stria terminal's, and the neurotransmitter corticotrophin-releasing factor, and (b) the lateral tegmental noradrenergic nuclei of the brain stem and the neurotransmitter norepinephrine.
Cue-triggered relapse involves the basolateral nucleus of the amygdala, the hippocampus and the neurotransmitter glutamate Knowledge of the neuroanatomy, neurophysiology, neurochemistry and neuropharmacology of addictive drug action in the brain is currently producing a variety of strategies for harmacotherapeutic treatment of drug addiction, some of which appear promising.

AB Background-Coronary artery calcium (CAC), carotid intima-media thickness, and left ventricular (LV) mass and geometry offer the potential to characterize incident cardiovascular disease (CVD) risk in clinically asymptomatic individuals. The objective of the study was to compare these cardiovascular imaging measures for their overall and sex-specific ability to predict CVD.
Methods and Results-The study sample consisted of 4965 Multi-Ethnic Study of Atherosclerosis participants (48% men; mean age, 62+/-10 years). They were free of CVD at baseline and were followed for a median of 5.8 years. There were 297 CVD events, including 187 coronary heart disease (CHD) events, 65 strokes, and 91 heart failure (HF) events. CAC was most strongly associated with CHD (hazard ratio [HR], 2.3 per 1 SD; 95% CI, 1.9 to 2.8) and all CVD events (HR, 1.7; 95% CI, 1.5 to 1.9). Most strongly associated with stroke were LV mass (HR, 1.3; 95% CI, 1.1 to 1.7) and LV mass/volume ratio (HR, 1.3; 95% CI, 1.1 to 1.6). LV mass showed the strongest association with HF (HR, 1.8; 95% CI, 1.6 to 2.1). There were no significant interactions for imaging measures with sex and ethnicity for any CVD outcome. Compared with traditional risk factors alone, overall risk prediction (C statistic) for future CHD, HF, and all CVD was significantly improved by adding CAC, LV mass, and CAC, respectively (all P<0.05).
Conclusions-There was no evidence that imaging measures differed in association with incident CVD by sex. CAC was most strongly associated with CHD and CVD; LV mass and LV concentric remodeling best predicted stroke; and LV mass best predicted HF. (Circ Cardiovasc Imaging. 2011;4:8-15.)

AB Background-Pluripotent stem cells represent one promising source for cellular cardiomyoplasty. In this study, we used cardiac magnetic resonance to examine the ability of highly enriched cardiomyocytes (CMs) derived from murine embryonic stem cells (ESC) to form grafts and improve contractile function of infarcted rat hearts.
Methods and Results-Highly enriched ESC-CMs were obtained by inducing cardiac differentiation of ESCs stably expressing a cardiac-restricted puromycin resistance gene. At the time of transplantation, enriched ESC-CMs expressed cardiac-specific markers and markers of developing CMs, but only 6% of them were proliferating. A growth factor-containing vehicle solution or ESC-CMs (5 to 10 million) suspended in the same solution was injected into athymic rat hearts 1 week after myocardial infarction. Initial infarct size was measured by cardiac magnetic resonance 1 day after myocardial infarction. Compared with vehicle treatment, treatment with ESC-CMs improved global systolic function 1 and 2 months after injection and significantly increased contractile function in initially infarcted areas and border zones. Immunohistochemistry confirmed successful engraftment and the persistence of alpha-actinin-positive ESC-CMs that also expressed alpha-smooth muscle actin. Connexin-43-positive sites were observed between grafted ESC-CMs but only rarely between grafted and host CMs. No teratomas were observed in any of the animals.
Conclusions-Highly enriched and early-stage ESC-CMs were safe, formed stable grafts, and mediated a long-term recovery of global and regional myocardial contractile function after infarction. (Circ Cardiovasc Imaging. 2011;4:33-41.)

AB Background-Heart failure survival models typically are constructed using Cox proportional hazards regression. Regression modeling suffers from a number of limitations, including bias introduced by commonly used variable selection methods. We illustrate the value of an intuitive, robust approach to variable selection, random survival forests (RSF), in a large clinical cohort. RSF are a potentially powerful extensions of classification and regression trees, with lower variance and bias.
Methods and Results-We studied 2231 adult patients with systolic heart failure who underwent cardiopulmonary stress testing. During a mean follow-up of 5 years, 742 patients died. Thirty-nine demographic, cardiac and noncardiac comorbidity, and stress testing variables were analyzed as potential predictors of all-cause mortality. An RSF of 2000 trees was constructed, with each tree constructed on a bootstrap sample from the original cohort. The most predictive variables were defined as those near the tree trunks (averaged over the forest). The RSF identified peak oxygen consumption, serum urea nitrogen, and treadmill exercise time as the 3 most important predictors of survival. The RSF predicted survival similarly to a conventional Cox proportional hazards model (out-of-bag C-index of 0.705 for RSF versus 0.698 for Cox proportional hazards model).
Conclusions-An RSF model in a cohort of patients with heart failure performed as well as a traditional Cox proportional hazard model and may serve as a more intuitive approach for clinicians to identify important risk factors for all-cause mortality. (Circ Cardiovasc Qual Outcomes. 2011;4:39-45.)

AB Background-The high mortality rate in patients with heart failure (HF) is influenced by presence of multiple comorbidities. Data are limited on the relative contributions of cardiovascular versus noncardiovascular diseases to death in individuals with HF in the community.
Methods and Results-We examined the incidence and predictors of cardiovascular versus noncardiovascular death in participants with HF in the Framingham Heart Study. Underlying, immediate, and contributing causes of death (3 key elements of the World Health Organization classification) were adjudicated by a 3-physician review panel. During 1971 to 2004, 1025 participants with HF died (499 men, mean [SD] age at death 79 [11] years), including 463 participants with left ventricular ejection fraction (LVEF) data. Cardiovascular disease was the cause of death in 66.1% overall. Stratified by LVEF, cardiovascular deaths occurred in 44.5% and 69.9% of those with preserved and reduced LVEF, respectively. Presence of reduced LVEF increased the risk of cardiovascular death, with odds ratios of 3.16 (95% confidence interval [CI], 1.73 to 5.78) in men and 2.39 (95% CI, 1.39 to 4.08) in women. Prior myocardial infarction was associated with increased cardiovascular death in women with HF (odds ratio, 1.87; 95% CI, 1.10 to 3.16) but not in men. The risk of cardiovascular disease death decreased in women (odds ratio after 1980, 0.41; 95% CI, 0.24 to 0.69) and men (odds ratio, 0.66; 95% CI, 0.41 to 1.07, P = 0.095) with HF over time. Infections and kidney disease emerged as key immediate and contributing causes of death, respectively.
Conclusions-Individuals with HF in the community often experience cardiovascular death, but noncardiovascular disease also contributes significantly especially among those with preserved LVEF. (Circ Heart Fail. 2011;4:36-43.)

AB Tight junctions restrict the paracellular movement of ions, solutes, drugs, and larger material across epithelia and endothelia. For practical purposes, the barrier can be modeled as having two components. The first is a system of small 4 angstrom radius pores lined or created by claudins. The pores show variable ionic charge selectivity and electrical resistance based on the pattern of claudin proteins expressed in a particular junction. Transport of compounds that are larger than 4 angstrom arc not subject to discrimination based on size or charge; they arc likely passing through transient breaks in the tight junction barrier. The magnitude of the first and second pathways varies among epithelia and is altered in response to physiological and pathological stimuli. Unfortunately, most studies of permeability use few tracer sizes and thus provide limited information on size-dependent changes in permeability. Here we describe a method for simultaneously measuring the size-dependence of apparent permeability using a continuous series of polyethylene polymers which allows quantification of both the pore and leak pathways.

AB Catheter-related bloodstream infections can be complicated to manage, but a growing body of evidence supports specific recommendations. In 2009, the Infectious Diseases Society of America published updated guidelines for the diagnosis and management of all intravascular catheter-related infections. Here we provide a focused review on the management of bloodstream infections in adult patients with short-term (not surgically implanted and not tunneled) central venous catheters, including peripherally inserted central catheters. This review should serve as a ready reference for providers (eg, hospitalists, surgeons, physician assistants, nurse practitioners, intensivists) managing adult patients with short-term central venous catheters in place.

AB A recently reported case of progressive vaccinia (PV) in an immunocompromised patient has refocused attention on this condition. Uniformly fatal prior to the licensure of vaccinia immune globulin (VIG) in 1978, PV was still fatal in about half of VIG-treated patients overall, with a greater mortality rate in infants and children. Additional therapies would be needed in the setting of a smallpox bioterror event, since mass vaccination following any variola virus release would inevitably result in exposure of immunocompromised people through vaccination or contact with vaccinees. Well-characterized animal models of disease can support the licensure of new products when human studies are not ethical or feasible, as in the case of PV. We chose vaccinia virus-scarified SCID mice to model PV. As in immunocompromised humans, vaccinia virus-scarified SCID animals develop enlarging primary lesions with minimal or no inflammation, eventual distal virus spread, and lethal outcomes if left untreated. Postexposure treatment with VIG slowed disease progression, caused local lesion regression, and resulted in the healthy survival of most of the mice for more than 120 days. Combination treatment with VIG and topical cidofovir also resulted in long-term disease-free survival of most of the animals, even when initiated 7 days postinfection. These results support the possibility that combination treatments may be effective in humans and support using this SCID model of PV to test new antibody therapies and combination therapies and to provide further insights into the pathogenesis and treatment of PV.

AB In orders to improve the early detection and diagnosis of cancer, give more accurate prognoses, stratify individuals by risk, predict response to treatment, and help the transition of basic research into clinical application, biomarkers are needed that accurately represent or predict clinical outcomes. To be useful in trails for chemopreventive agent development, biomarkers must be subject to modulation, easy to obtain and quantify, and have biological meaning, ideally representing steps in well-understood carcinogenic pathways. Though difficult to validate fully, wisely chosen biomarkers in early-phase trails can inform the prioritization of large-scale, long-term trails that measure clinical outcomes. When well-designed, smaller trails using biomarkers as surrogate endpoints should promote faster decisions regarding which targeted preventive agents to pursue, promising greater progress in the personalization of medicine. Biomarkers could become useful in distinguishing indolent from aggressive forms of ductal carcinoma in situ as well as localized invasive breast and prostate cancer, lesions that are often overtreated. Chemopreventive strategies that reduce the progression of early forms of premalignancy can benefit patients not only by reducing their risk of cancer and death from cancer but also by reducing their need for invasive interventions. Genomic and proteomic methods offer the possibility of revealing new potential markers, especially for diseases whose biology is complex or not well understood. Panels of markers may be used to accommodate the molecular heterogencity of cancers. Biomarkers in phase 2 prevention trails of combinations of chemopreventive drugs have been used to demonstrate synergistic action of multiple agents, allowing use of lower doses, with less toxicity, a critical feature of interventions intended for cancer prevention.

AB Purpose: Brain metastases of breast cancer contribute significantly to patient morbidity and mortality. We have tested pazopanib, a recently approved antiangiogenic drug that targets VEGFR1, VEGFR2, VEGFR3, PDGFR beta, PDGFR alpha, and c-kit, for prevention of experimental brain metastases and mechanism of action.
Experimental Design: In vitro assays included B-Raf enzymatic assays, Western blots, and angiogenesis assays. For in vivo assays, HER2 transfectants of the brain seeking sublines of MDA-MB-231 cells (231-BRHER2) and MCF7 cells (MCF7-HER2-BR3, derived herein) were injected into the left cardiac ventricle of mice and treated with vehicle or pazopanib beginning on day 3 postinjection. Brain metastases were counted histologically, imaged, and immunostained.
Results: Treatment with 100 mg/kg of pazopanib resulted in a 73% decline in large 231-BR-HER2 metastases (P < 0.0001) and a 39% decline in micrometastases (P = 0.004). In vitro, pazopanib was directly antiproliferative to 231-BR-HER2 breast cancer cells and inhibited MEK and ERK activation in vitro despite B-Raf and Ras mutations. Enzymatic assays demonstrated that pazopanib directly inhibited the wild type and exon 11 oncogenic mutant, but not the V600E mutant forms of B-Raf. Activation of the B-Raf targets pERK1/2 and pMEK1/2 was decreased in pazopanib-treated brain metastases whereas blood vessel density was unaltered. In the MCF7-HER2-BR3 experimental brain metastasis model, pazopanib reduced overall brain metastasis volume upon magnetic resonance imaging (MRI) by 55% (P = 0.067), without affecting brain metastasis vascular density.
Conclusions: The data identify a new activity for pazopanib directly on tumor cells as a pan-Raf inhibitor and suggest its potential for prevention of brain metastatic colonization of HER2(+) breast cancer. Clin Cancer Res; 17(1); 142-53. (C) 2010 AACR.

AB BACKGROUND: Sativex(R), a cannabis extract oromucosal spray containing Delta(9)-tetrahydrocannabinol (THC) and cannabidiol (CBD), is currently in phase III trials as an adjunct to opioids for cancer pain treatment, and recently received United Kingdom approval for treatment of spasticity. There are indications that CBD modulates THC's effects, but it is unclear if this is due to a pharmacokinetic and/or pharmacodynamic interaction.
METHODS: Cannabis smokers provided written informed consent to participate in this randomized, controlled, double-blind, double-dummy institutional review board-approved study. Participants received 5 and 15 mg synthetic oral THC, low-dose (5.4 mg THC and 5.0 mg CBD) and high-dose (16.2 mg THC and 15.0 mg CBD) Sativex, and placebo over 5 sessions. CBD, THC, 11-hydroxy-THC, and 11-nor-9-carboxy-THC were quantified in plasma by 2-dimensional GC-MS. Lower limits of quantification were <= 0.25 mu g/L.
RESULTS: Nine cannabis smokers completed all 5 dosing sessions. Significant differences (P < 0.05) in maximum plasma concentrations (C-max) and areas under the curve from 0-10.5 h postdose (AUC(0 -> 10.5)) for all analytes were found between low and high doses of synthetic THC and Sativex. There were no statistically significant differences in C-max, time to maximum concentration or in the AUC(0 -> 10.5) between similar oral THC and Sativex doses. Relative bioavailability was calculated to determine the relative rate and extent of THC absorption; 5 and 15 mg oral THC bioavailability was 92.6% (13.1%) and 98.8% (11.0%) of low- and high-dose Sativex, respectively.
CONCLUSION: These data suggest that CBD modulation of THC's effects is not due to a pharmacokinetic interaction at these therapeutic doses. (C) 2010 American Association for Clinical Chemistry

AB BACKGROUND: Accurate measurement of free thyroxine (FT(4)) is important for diagnosing and managing thyroid disorders. Most laboratories measure FT(4) by direct analogue immunoassay methods. The validity of these methods have recently been questioned. The inverse log-linear relationship between FT(4) and thyroid-stimulating hormone (TSH) is well described and provides a physiological rationale on which to base an evaluation of FT(4) assays.
METHODS: The study included 109 participants for whom FT(4) measurement was requested by their clinician. Samples were selected for inclusion to reflect a wide spectrum of TSH and albumin results. FT(4) and TSH were measured by use of the Siemens Immulite immunoassay (IA). FT(4) was also measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS) (MS-FT(4)).
RESULTS: The inverse log-linear correlation coefficient between TSH and FT(4) was significantly better (P < 0.0001) for MS-FT(4) (0.84, 95% CI, 0.77-0.88) than for IA-FT(4) (0.45, 95% CI, 0.29-0.59). IA-FT(4) showed a significant correlation with albumin (Spearman correlation coefficient 0.45, 95% CI, 0.29-0.5, P < 0.0001) and thyroxine-binding globulin (TBG) (Spearman correlation coefficient 0.23, 95% CI, 0.05-0.41, P = 0.02). In contrast, FT(4) measurement by LC-MS/MS did not show a significant correlation with albumin or TBG.
CONCLUSIONS: The inverse log-linear relationship between FT(4) and TSH was significantly better for FT(4) measured by LC-MS/MS than by IA. The MS-FT(4) method therefore provides FT(4) results that agree clinically with those obtained for TSH. Additionally, the significant correlation between IA-FT(4) with albumin and TBG suggests that this FT(4) method depends on binding protein concentrations and consequently does not accurately reflect FT(4).

While vaccination at birth with Mycobacterium bovis Bacilli Calmette-Guerin (BCG) protects against severe childhood tuberculosis, there is no consensus as to which components of the BCG-induced immune response mediate this protection. However, granulysin and perforin, found in the granules of cytotoxic T lymphocytes and Natural Killer (NK) cells, can kill intracellular mycobacteria and are implicated in protection against Mycobacterium tuberculosis.

We compared the cellular expression of granulysin and perforin cytolytic molecules in cord blood and peripheral blood from 10-week-old infants vaccinated at birth with either Japanese or Danish BCG, administered either intradermally or percutaneously. Results. In cord blood, only CD56(+) NK cells expressed granulysin and perforin constitutively. These cytolytic mediators were upregulated in CD4(+) and CD8(+) cord blood cells by ex vivo stimulation with BCG but not with PPD. Following BCG vaccination of neonates, both BCG and PPD induced increased expression of granulysin and perforin by CD4(+) and CD8(+) T cells. There was no difference in expression of cytolytic molecules according to vaccination route or strain. Conclusions. Constitutive expression of perforin and granulysin by cord blood NK-cells likely provides innate immunity, while BCG vaccination-induced expression of these cytolytic mediators may contribute towards protection of the neonate against tuberculosis.

AB Chronic granulomatous disease (CGD) and inflammatory bowel disease (IBD) have overlapping gastrointestinal manifestations. Serum antibodies to intestinal microbial antigens in IBD are thought to reflect a loss of tolerance in the setting of genetically encoded innate immune defects. CGD subjects studied here, with or without colitis, had considerably higher levels of ASCA IgA, ASCA IgG, anti-OmpC, anti-I2, and anti-CBir1, but absent to low pANCA, compared to IBD-predictive cutoffs. Higher antibody levels were not associated with a history of colitis. Except for higher ASCA IgG in subjects <18 years, antibody levels were not age-dependent. In comparison, 7 HIES subjects expressed negative to low antibody levels to all of these antigens; none had colitis. Our results suggest that markedly elevated levels of antimicrobial antibodies in CGD do not correlate with a history of colitis but may reflect a specific defect in innate immunity in the face of chronic antigenic stimulation.

AB Background and objectives Poor linear growth is a well described complication of chronic kidney disease (CKD). This study evaluated whether abnormal birth history defined by low birth weight (LBW; <2500 g), prematurity (gestational age <36 weeks), small for gestational age (SGA; birth weight <10th percentile for gestational age), or intensive care unit (ICU) at birth were risk factors for poor growth outcomes in children with CKD.
Design, setting, participants, & measurements Growth outcomes were quantified by age-sex-specific height and weight z-scores during 1393 visits from 426 participants of the Chronic Kidney Disease in Children Study, an observational cohort of children with CKD. Median baseline GFR was 42.9 ml/min per 1.73 m(2), 21% had a glomerular diagnosis, and 52% had CKD for >= 90% of their lifetime.
Results A high prevalence of LBW (17%), SGA (14%), prematurity (12%), and ICU after delivery (40%) was observed. Multivariate analyses demonstrated a negative effect of LBW (-0.43 +/- 0.14; P < 0.01 for height and 0.37 +/- 0.16; P = 0.02 for weight) and of SGA (-0.29 +/- 0.16; P = 0.07 for height and 0.41 +/- 0.19; P = 0.03 for weight) on current height and weight. In children with glomerular versus nonglomerular diagnoses, the effect of SGA (-1.08 versus -0.18; P = 0.029) on attained weight was more pronounced in children with a glomerular diagnosis.
Conclusions LBW and SGA are novel risk factors for short stature and lower weight percentiles in children with mild to moderate CKD independent of kidney function. Clin J Am Soc Nephrol 6: 14-21, 2011. doi: 10.2215/CJN.08481109

AB Background: The proteasome inhibitor bortezomib sensitizes tumor cells to chemotherapy-induced apoptosis. In preclinical non-small-cell lung cancer (NSCLC) models, p53-dependent growth arrest after bortezomib treatment resulted in reduced cytotoxicity if bortezomib preceded docetaxel. The reverse sequence of docetaxel before bortezomib was associated with increased apoptosis, cleavage of caspase-3 and PARP (poly [ADP-ribose] polymerase), and reduction in Bcl-2. A prospective randomized phase II trial of concurrent versus sequential docetaxel and bortezomib was conducted to assess whether administration sequence resulted in measurable clinical differences.
Patients and Methods: Previously treated patients with advanced NSCLC were randomized to concurrent (CON) or sequential (SEQ) docetaxel (75 mg/m(2) intravenous [I.V.]) followed by bortezomib, every 3 weeks. In the CON arm, bortezomib (1.6 mg/m(2) I.V.) was given on days 1 and 8, and in the SEQ arm, it was given on days 2 and 8. Previous erlotinib as well as treated or controlled brain metastases were allowed. The primary endpoint was objective response rate (RR); progression-free (PFS) and overall survival (OS) were secondary endpoints. Results: Eighty-one patients were randomized (40 CON and 41 SEQ). Grade 3+ toxicities were mostly due to myelosuppression. One patient each had grade 4 hyponatremia and syncope. Toxicities were similar between the arms. There was 1 treatment-related death in the SEQ arm. There were 8 partial responders, 4 in each arm, for an overall RR of 10%. Disease control rate was similar in both arms (50% vs. 49%). Median PFS was 12 weeks in the CON arm and 11 weeks in the SEQ arm. Median OS times in the CON and SEQ arms were 13.3 and 10.5 months, respectively.
Conclusion: Docetaxel plus bortezomib given sequentially or concurrently has similar RR and PFS. Median survival in the SEQ arm exceeds published survival estimates for either agent alone or in combination. Any further studies in this population would require molecular characterization of a phenotype most likely to benefit from proteasome inhibitor therapy.

AB Decreases in levels of sex hormones occur with aging. Observational studies have found associations of low testosterone concentrations in older men with adverse symptoms; however, these associations do not prove causality. Therefore, the question arises whether to treat older men whose serum testosterone is low. In 2009, the Testosterone Trial (T Trial) was funded to examine the efficacy of therapy in 800 elderly men with low testosterone levels; potentially associated symptoms; and abnormalities in physical, sexual, or cognitive function or vitality.

AB Objectives: Atomoxetine is commonly used to treat attention-deficit hyperactivity disorder (ADHD) in children with a broad range of cognitive abilities. We examined the association between level of cognitive functioning as determined by IQ and clinical response during treatment with atomoxetine.
Methods: The records of all the children and adolescents treated with atomoxetine at a university clinic in Catania, Italy, over a 3-year period were examined. A total of 55 clinically referred children and adolescents (aged 5-15 years, 53 males) with ADHD were treated with atomoxetine (10-110 mg/day; mean: 1.28 mg/kg/day) for a period ranging from 2 to 168 weeks (mean: 57.3 +/- SD 39.4, median: 56). The IQ was assessed as part of the diagnostic evaluation prior to starting treatment. During treatment, clinical outcome was rated on the Clinical Global Impression-Improvement (CGI-I) and CGI-Severity (CGI-S) scales.
Results: The IQ ranged from 43 to 117 (mean: 80.6 +/- SD 18.6, median: 84). The IQ and final CGI-I scores were negatively correlated (r = -0.68; p < 0.01). Children and adolescents with an IQ <85 were less likely to be responders (defined as a final CGI-I score of 1 or 2) than children and adolescents with an IQ >= 85 (20.71% vs 76.9%; p < 0.001). None of the patients discontinued atomoxetine due to adverse effects, while treatment was discontinued in 20 subjects due to a lack of efficacy or ambivalence of parents about pharmacological treatment.
Conclusions: Atomoxetine appears to be less effective in children and adolescents with an IQ <85 than in children and adolescents in the average range of cognitive functioning. This difference is not accounted for by differences in the severity of ADHD symptoms, co-morbidity or reduced tolerability to the medication. These findings suggest that, in order to be fully informative, clinical trials of medications for ADHD should also include children and adolescents functioning in the borderline and cognitive disability range.

AB Tolerance development after successful long-term treatment of bipolar disorder is under recognized, as are ways to prevent or show its occurrence or reverse it once it has occurred. We review the clinical literature which suggests that tolerance can develop to most treatment approaches in bipolar illness and present an animal model of tolerance development to anticonvulsant effects of carbamazepine or lamotrigine on amgydala-kindled seizures. In this model tolerance does not have a pharmacokinetic basis, but is contingent upon the drug being present in the brain at the time of amygdala stimulation. The occurrence of seizures in the absence of drug is sufficient to reverse tolerance and re-establish anticonvulsant efficacy. Based on the model, we hypothesize that some episode-induced compensatory adaptive changes in gene expression fail to occur in tolerant subjects and that episodes off medication re-induce these changes and renew drug effectiveness. Approaches that slow or reverse tolerance development in the animal model are reviewed so that they can be tested for their applicability in the clinic. Criteria for assessing tolerance development are offered in the hope that this will facilitate a more systemic literature about its prevalence, prevention, and reversal. Careful longitudinal monitoring of episode occurrence is essential to understanding tolerance development in the affective disorder and its treatment.

AB Epigenetics involves molecular mechanisms related to gene expression independent of DNA sequence, mostly mediated by modification of chromatin histones. It has recently been suggested that these transcriptional changes may be implicated in the pathophysiology of mood disorders. In addition, histone deacetylase (HDAC) inhibitors have been shown to control epigenetic programming associated with the regulation of cognition and behavior, and may reverse dysfunctional epigenetic regulation associated with early life events in preclinical models. In this context, the active and continuous adaptation of chromatin, and the access of gene promoters to transcription factor mechanisms may represent a potential therapeutic target in the treatment of mood disorders such as bipolar disorder (BD) and major depressive disorder (MDD). Notably, the standard mood stabilizer valproate (VPA) has been shown to modulate the epigenome by inhibiting HDACs. However, several potential limitations are associated with this class of agents, including lack of selectivity for specific HDAC isoforms as well as risk of potentially serious side effects. Further studies regarding the potential role of chromatin remodeling in the mechanism of action of antidepressants and mood stabilizers are necessary to clarify the potential role of this class of agents as therapeutics for mood disorders.

AB Social fears emerging in adolescence can have negative effects on emotional well-being. Yet the mechanisms by which these risks occur are unknown. One possibility is that associative learning results in fears to previously neutral social stimuli. Such conditioned responses may alter subsequent processing of social stimuli. We used a novel conditioning task to examine how associative processes influence social fear and attention orienting in adolescents. Neutral photographs were paired with socially rewarding or aversive stimuli during conditioning; a dot-probe task then assessed biases in attention orienting. The social conditioning task modified subjective ratings of the neutral stimuli. Moreover, for the neutral stimulus that was paired with the aversive stimulus, the strength of conditioning showed a relationship with subsequent attentional vigilance. The findings elucidate mechanisms by which negative peer experiences during adolescence may affect emotional processing.

AB Downing and Peelen have produced an excellent review synthesizing the current literature on the processing of body stimuli in visual cortex. However, while they consider the extrastriate body area (EBA) and fusiform body area (FBA) together, these regions are physically separate in cortex and likely contribute differentially to person perception. Here, we evaluate the hierarchical view of processing in EBA and FBA and highlight the visual field biases in these regions, which may provide insight into their origin and functional roles.

AB Investigations into the neurobiological substrates underlying urge are important for developing better understanding and treatment for impulse-control disorders. We characterize the phenomenon based on normal bodily (interoceptive) urges. Features include the following: a preceding awareness of an uncomfortable bodily sensation, a sense of urgency that action must be taken, rising distress when action is delayed, a temporary (e. g., a few minutes in length) ability to suppress or manifest the action voluntarily, subsequent relief once action is taken, association with an action that is necessary to survival. We compare and contrast these characteristics with those described by Tourette syndrome patients as the urge to tic, and highlight several unknowns which merit further investigation.

AB Disease prediction based on longitudinal data can be done using various modeling approaches. Alternative approaches are compared using data from a longitudinal study to predict the onset of disease. The data are modeled using linear mixed-effects models. Posterior probabilities of group membership are computed starting with the first observation and sequentially adding observations until the subject is classified as developing the disease or until the last measurement is used. Individuals are classified by computing posterior probabilities using the marginal distributions of the mixed-effects models, the conditional distributions (conditional on the group-specific random effects), and the distributions of the random effects.

AB As collections of 2D/3D images continue to grow, interest in effective ways to visualize and explore the statistical morphological properties of a group of images has surged. Recently, deformation models have emerged as simple methods to capture the variability and statistical properties of a collection of images. Such models have proven to be effective in tasks such as image classification, generation, registration, segmentation, and analysis of modes of variation. A crucial element missing from most statistical models has been an effective way to summarize and visualize the statistical morphological properties of a group of images. This paper evaluates different visualization techniques that can be extended and used to illustrate the information captured by such statistical models. First, four illustration techniques are described as methods to summarize the statistical morphological properties as captured by deformation models. Second, results of a user study conducted to compare the effectiveness of each visualization technique are presented. After comparing the performance of 40 subjects, we found that statistical annotation techniques present significant benefits when analyzing the structural properties of a group of images.

AB Background: With increasing knowledge of the molecular pathways contributing to the progression of neurofibromatosis type 1 (NF1)-related plexiform neurofibroma (PN), the number of clinical trials for PNs has increased. However, little is known about the experiences of families with children with NF1 participating in clinical trials.
Method: A 47-item anonymous survey, designed to assess experiences in research, was sent to parents with a child with NF1 and PNs who was evaluated at the National Cancer Institute (NCI) for a clinical trial.
Results: Sixty-four (85%) parents completed the paper or online questionnaire. Fifty-nine percent of the children were male; 44% were 11 years or older upon enrollment. Most parents reported understanding the purpose of the study, possible side effects, and their right to withdraw. Of respondents whose child had participated in a placebo-controlled trial, 100% said they understood the reason for the placebo at least somewhat. Seventy-four percent felt that study participation helped their child; most would "definitely" or "probably" participate in a future study, including a placebo-controlled trial, and particularly those assessing cognitive functioning or pain. Overall satisfaction with participation was high and correlated with fewer transportation problems, fewer study-related financial difficulties, and fewer school problems for the child (ps<.05).
Conclusions: Most parents of children with NF1 who participated in research at the NCI reported a positive impact and would participate in future studies. Respondents identified several areas for improvement. This report may help plan future studies to optimize experiences of children and their families enrolled in clinical trials.

AB Autofluorescence arising from normal tissues can compromise the sensitivity and specificity of in vivo fluorescence imaging by lowering the target-to-background signal ratio. Since bioluminescence resonance energy transfer quantum dot (BRET-QDot) nano-particles can self-illuminate in near-infrared in the presence of the substrate, coelenterazine, without irradiating excitation lights, imaging using BRET-QDots does not produce any autofluorescence. In this study, we applied this BRET-QDot nano-particle to the in vivo lymphatic imaging in mice in order to compare with BRET, fluorescence or bioluminescence lymphatic imaging. BRET-QDot655, in which QDot655 is contained as a core, was injected at different sites (e. g. chin, ear, forepaws and hind paws) in mice followed by the intravenous coelenterazine injection, and then bioluminescence and fluorescence imaging were serially performed. In all mice, each lymphatic basin was clearly visualized in the BRET imaging with minimal background signals. The BRET signal in the lymph nodes lasted at least 30 min after coelenterazine injections. Furthermore, the BRET signal demonstrated better quantification than the fluorescence signal emitting from QDot655, the core of this BRET particle. These advantages of BRET-QDot allowed us to perform real-time, quantitative lymphatic imaging without image processing. BRET-Qdots have the potential to be a robust nano-material platform for developing optical molecular imaging probes. Copyright (C) 2010 John Wiley & Sons, Ltd.

AB Muenke syndrome is defined by the presence of the p.P250R mutation in FGFR3, and is an autosomal dominant disorder with incomplete penetrance and variable expressivity. Typical manifestations of Muenke syndrome include coronal craniosynostosis, hearing loss, developmental delay/cognitive impairment, and relatively minor hand and foot anomalies. Clinical diagnosis is difficult because of phenotypic overlap and diagnosis is always made by molecular testing. Optimal management of patients involves a coordinated, multidisciplinary team familiar with the condition. Copyright (C) 2011 S. Karger AG, Basel

AB Uncommon craniosynostosis syndromes, while individually less well characterized than more common conditions such as Apert, Crouzon, Pfeiffer, Muenke, and Saethre-Chotzen syndromes, comprise a significant proportion of craniosynostosis cases when considered in sum. Thirteen of these rare syndromes are covered here with respect to nosology, associated clinical characteristics, and molecular genetics. They were selected for discussion in this chapter due to recent molecular advances therein that can significantly enhance clinicians' ability to diagnose and counsel patients with these syndromes. The syndromes discussed here include Antley-Bixler syndrome, Baller-Gerold syndrome, Beare-Stevenson cutis gyrata syndrome, Bohring-Opitz syndrome, C (Opitz trigonocephaly) syndrome, Carpenter syndrome, Crouzon syndrome with acanthosis nigricans, Jackson-Weiss syndrome, Jacobsen syndrome, Loeys-Dietz syndrome type I, osteoglophonic dysplasia, P450 oxidoreductase deficiency, and Shprintzen-Goldberg syndrome.

AB Background/Aims: Suicidal ideations (SI) indicate and predict psychological distress. We examined the prevalence of SI among early adolescents and its association with parental war participation, personal, behavioral, and sociodemographic characteristics. Methods: We performed a cross-sectional questionnaire study on 803 12-year-old adolescents. Data were collected using a sociodemographic questionnaire, the Junior Eysenck Personality Questionnaire and Children Depression Inventory. Unintentional injuries, physical fighting, and involvement in bullying behavior were assessed using questions from the World Health Organization (WHO) survey Health Behavior in School-aged Children. Suicidal ideations were assessed with three dichotomous items. Results: There were no gender differences in SI prevalence. SI in males were associated with lower maternal education, crowded families, birth order, parental war participation, physical fighting, being bullied, and substance use. In females, we found associations with lower parental educational level, number of brothers, lower perception of the relationship with parents, parental relationship, family cohesion and parental control, negative attitude toward school, rare church attendance, fighting, and being bully or bullied. Depressive symptoms and SI were associated in both genders. Conclusions: SI showed gender-specific associations that may partially be explained with parental war involvement. These findings may have potentially important clinical and preventive implications.

AB The primate orbitofrontal cortex (OFC) is often treated as a single entity, but architectonic and connectional neuroanatomy indicate that it has distinguishable parts. Nevertheless, few studies have attempted to dissociate the functions of its subregions. Here we review findings from recent neuropsychological and neurophysiological studies that do so. The lateral OFC seems to be important for learning, representing, and updating specific object-reward associations. The medial OFC seems to be important for value comparisons and choosing among objects on that basis. Rather than viewing this dissociation of function in terms of learning versus choosing, however, we suggest that it reflects the distinction between contrasts and comparisons: differences versus similarities. Making use of high-dimensional representations that arise from the convergence of several sensory modalities, the lateral OFC encodes contrasts among outcomes. The medial OFC reduces these contrasting representations of value to a single dimension, a common currency, in order to compare alternative choices.

AB The three mammalian bombesin (Bn) receptors (gastrin-releasing peptide [GRP] receptor, neuromedin B [NMB] receptor, BRS-3) are one of the classes of G protein-coupled receptors that are most frequently overexpress/ectopically expressed by common, important malignancies. Because of the clinical success of somatostatin receptor-mediated imaging and cytotoxicity with neuroendocrine tumors, there is now increasing interest in pursuing a similar approach with Bn receptors. In the last few years then have been more than 200 studies in this area. In the present paper, the in vitro and in vivo results, as well as results of human studies from many of these studies are reviewed and the current state of Bn receptor-mediated imaging or cytotoxicity is discussed. Both Bn receptor-mediated imaging studies as well as Bn receptor-mediated tumoral cytotoxic studies using radioactive and non-radioactive Bn-based ligands are covered.

AB Vitamin D deficiency has been linked to an increased risk of hypertension, diabetes, congestive heart failure, peripheral arterial disease, myocardial infarction, stroke, and related mortality, even after adjustment for traditional cardiovascular risk factors. Accumulating evidence from experimental, clinical, and epidemiological studies suggests that vitamin D may also be associated with several indices of vascular function, including the development and progression of atherosclerotic cardiovascular disease. These findings may provide at least a partial explanation for several recent epidemiologic studies implicating low vitamin D status in the pathogenesis of cardiovascular disease. However, many questions still remain. Only a handful of studies are currently available, and the results of these studies have generally been mixed. Additionally, it is unknown whether findings differ across varied subpopulations, including minority subgroups in the United States, younger adults, and those residing in areas with varying amounts of regular sunlight. Furthermore, the exact mechanism by which vitamin D may influence the atherosclerotic disease process has not yet been completely elucidated. In addition, if vitamin D is important in the etiology of atherosclerosis, it is unclear at what stage(s) in the atherosclerotic disease process vitamin D may exert its effects. Large-scale, well-conducted, placebo controlled clinical trials testing the efficacy of vitamin D supplementation in delaying, slowing, or reverting the atherosclerotic disease process have not yet been conducted. Until the results of these studies are available, we believe it is premature to recommend vitamin D as a therapeutic option in atherosclerosis.

Several recent studies have reported the occurrence of late-onset neutropenia (LON) following the use of rituximab or rituximab-based therapies. While this phenomenon is typically self-limiting and of no clinical significance, recognizing its existence is important given the expanding use of rituximab in both hematologic and nonhematologic disorders. This review discusses the incidence of LON and explores several hypotheses that have been proposed to explain its occurrence.
Recent findings
While the etiology of LON is uncertain and poorly understood, mechanisms that have been suggested include the production of antineutrophil antibodies following rituximab, the expansion of large granular lymphocyte (LGL) populations that may induce neutrophil apoptosis through Fas and Fas-ligand interactions, and aberrant B-cell reconstitution following rituximab leading to immune dyscrasias and the development of neutropenia. We explored an alternative hypothesis that LON following rituximab is caused by perturbations of granulocyte homeostasis, mediated by a complex interaction between B-cell recovery and the chemokine stromal-derived factor-1 (SDF-1).
Summary
While rituximab has been associated with both early and late neutropenia, LON occurring several weeks to several months after the administration of rituximab is a distinct biologic phenomenon that appears to be related to B-cell recovery. Though it occurs frequently, it is a self-limiting process and is rarely associated with significant clinical sequelae.

AB Purpose of review
HIV infection is controlled but not cured by combination antiretroviral therapy. HIV may persist for a number of reasons, including ongoing cycles of HIV infection or viral persistence as latent, or HIV replication in long-lived cells containing HIV proviruses. Therapeutic consequences of these alternative mechanisms are significant and distinct. If ongoing replication remains during current antiretroviral therapy, then improvements in potency will be useful in eradication strategies. Alternatively, long-lived cells with integrated proviruses will not be affected by improvements in therapy directed against active infection, and new strategies will be necessary for HIV eradication. Technologic advances have made it possible to carry out a series of drug intensification protocols in well suppressed patients; these and other analyses for HIV replication have been useful to elucidate the nature of HIV persistence on therapy.
Recent findings
A number of clinical studies intensifying antiretroviral therapy carried out in the last several years have yielded new findings regarding the ability to detect the presence of ongoing replication. Decreases in persistent viremia have not been consistently detected in individuals on potent combination antiretroviral therapy. Evidence for persistent replication has been reported in patients using sensitive assays of cell-associated HIV.
Summary
HIV viremia persists despite combination antiretroviral therapy. Antiretroviral drug intensification does not lower the level of HIV measured in plasma, suggesting current therapy arrests active virus replication. HIV eradication will most likely require therapy in addition to potent antiretroviral therapy.

AB Purpose of review
HIV-infected cells persisting in the face of highly active antiretroviral therapy are arguably the greatest hurdle to eradication of the virus from the body. Complementary strategies aimed at selective killing of infected cells are described.
Recent findings
Pioneered by research in the cancer field, various approaches are under development for selective killing of HIV-infected cells. These include targeted cytotoxic proteins, adoptive cell therapy, cytocidal virotherapy, and targeted nonbiological drug carriers.
Summary
These developmental efforts may provide a critical complement to antiretroviral therapy in efforts to achieve HIV eradication, or a 'functional cure' whereby therapy can be stopped without viral rebound.

AB Transient Receptor Potential Vanilloid Type 1 is a prominent "pain" receptor expressed in sensory afferent neurons. TRPV1 on peripheral nerve terminals detects a variety of noxious stimuli generated at sites of injury and inflammation, and in turn, drives the excitation and sensitization of C-fiber neurons. Significantly, TRPV1 is also located on the central terminals of sensory neurons projecting to the spinal cord and brainstem. These TRPV1 channels appear to stimulate the secretion of glutamate. Further, TRPV1 is expressed diffusely in the brain and there is emerging evidence for TRPV1 modulating transmission at various brain synapses. Here we discuss our current understanding of the potential roles for TRPV1 in synaptic transmission.

AB Cushing's syndrome is characterized by exposure to excess glucocorticoid. It can be caused by exogenous administration of these compounds, usually in supraphysiologic treatment doses. Endogenous Cushing's syndrome is caused either by excessive ACTH production from a pituitary or other tumor, or by autonomous adrenal cortisol production. Clinical features suggestive of the disorder should prompt biochemical screening. Case detection of this rare disorder is justified by the high standardized mortality rate, which is normalized after successful treatment.

AB In this chapter, we discuss clinical and molecular findings of micronodular adrenal hyperplasias (MAHs) that lead to ACTH-independent Cushing syndrome. We focus on the role of genetic defects in cyclic AMP (cAMP) signaling-related molecules, namely PRKAR1A, GNAS, PDE11A, and PDE8B; molecular defects in the phosphodiesterases (PDE) family are the most recently discovered genetic defects predisposing to adrenocortical tumor formation. The prototype of these disorders was Carney complex (CNC) in the context of which the first MAH was described: primary pigmented nodular adrenocortical disease or PPNAD. PPNAD is due to defects in PRKAR1A, the gene that functions as a receptor for the cAMP. In contrast to GNAS and PRKAR1A, defects in PDE genes are associated more frequently with incomplete penetrance. Identifying low-penetrance mutations in more than one PDE in patients with MAHs is suggestive for a complementary role of the different PDEs in the adrenal gland, and possible involvement of other members of this gene family in adrenocortical tumors and ACTH-independent Cushing syndrome.

AB Cysteine proteases have been discovered in various bloodfeeding ectoparasites. Here, we assemble the available information about the function of these peptidases and reveal their role in hematophagy and parasite development. While most of the data shed light on key proteolytic events that play a role in arthropod physiology, we also report on the association of cysteine proteases with arthropod vectorial capacity. With emphasis on ticks, specifically Ixodes ricinus, we finally propose a model about the contribution of cysteine peptidases to blood digestion and how their concerted action with other tick midgut proteases leads to the absorbance of nutrients by the midgut epithelial cells.

ID POLYMER NANOPARTICLES; SENSOR
AB Quantum dots (QD) are fluorescent nanocrystals that are highly useful in imaging and flow cytometric analyses. During routine use of monoclonal antibody conjugates of QD, we have occasionally seen partial or total loss of fluorescence when using certain lots of fixative solutions. We hypothesized that a low level contamination with heavy metal cations was responsible, since low level metal contaminants are not uncommon in formalin solutions. By titrating known concentrations of heavy metal cations into staining solutions, we found that millimolar concentrations of ferrous and zinc ions, and as low as 50 nanomolar cupric ions, completely eliminated QD fluorescence. By mass spectroscopic quantification of metals in commercial fixative solutions previously shown to perform poorly or well with regard to QD fluorescence, we confirmed that the presence of copper in solution was correlated with poor performance. Notably, prior addition of EDTA to chelate the divalent cations in these solutions prevented the inhibition of QD fluorescence. Finally, the copper-induced loss of QD fluorescence is irreversible: cells labeled with QD are highly fluorescent and can be rendered nonfluorescent by the addition of cupric sulfate, even after washing extensively. Indeed, these cells can then be successfully stained with other QD reagents, providing a method for immunofluorescence restaining of cells without contaminating fluorescence from the first stain.

AB Background: Quantitative flow cytometry (QFCM) is being applied in the clinical flow cytometry laboratory. Quantitative normal T-cell CD4 expression represents a biologic standard and quality control agent. However, low levels of CD4 expression were detected in normal T-cells in Hairy Cell Leukemia (HCL) samples.
Methods: The QuantiBrite System (R) was used to determine the level of CD4 expression (mean antibody bound per cell, ABC) in fresh and shipped HCL blood and fresh normal donor blood (NDB). The effects of shipping, lysing reagent, cell preparation method, and antibody lot were evaluated.
Results: Shipped HCL specimens (n = 69) had a significantly lower mean CD4 ABC of 38,788 (CV = 9.1%) compared to fresh specimens (n = 105) CD4 value of 40,330 (CV = 8.4%) (P < 0.05). In NDB, significant differences were seen for fresh versus shipped specimens using the stain/lyse method but not for lyse/stain method. Consistent differences in CD4 ABC based upon antibody lot were observed in fresh HCL and NDB samples. Stain/lyse and lyse/stain methods using NH(4)Cl lyse were compared in NDB using identical samples and antibodies. The NDB CD4 ABC values obtained with the lyse (NH(4)Cl)/stain method (45,562, 3.7% CV) were lower than those obtained with the stain/lyse (NH(4)Cl) method (49,955, 3.3% CV) with P < 0.001.
Conclusions: CD4 expression in HCL patient samples is not inherently different from that observed in NDB and therefore may serve as a biological control in clinical QFCM. Technical variables impact significantly on QFCM of CD4. Published 2010 Wiley-Liss, Inc.(dagger)

AB Neurofilaments (NFs) belong to type 1 V family of intermediate filaments and are the most abundant proteins of the nervous system. Mammalian NF triplet proteins constitute three subunits, low molecular weight (NF-L), medium molecular weight (NF-M), and high molecular weight (NF-H) subunit proteins. The NF-M/H carboxy terminal tail domain has multiple KSP repeats (40 >= 100) depending upon species, the phosphorylation of which regulates axonal caliber and axonal transport. The NF tail domain contains phosphorylation sites for proline directed kinases such as mitogen activated protein kinases (MAPKs), cyclin dependent protein kinase 5 (Cdk5), c-Jun amino terminal kinase (JNKs), and glycogen synthase kinase-3 (GSK-3). The signaling cascades involved in NF phosphorylation like MAPKs and Cdk5 can also be affected by myelin associated glycoprotein (MAG). MAG activates the Erk1/2 and Cdk5 activities due to the glial/axon interaction and increases the proline directed Ser/Thr phosphorylation of C-terminal domain of NF-M/H. The NF phosphorylation is topographically regulated. In normal neurons, NFs are phosphorylated only in the axonal compartment. However, in degenerative neurons such as Alzheimer's disease (AD), spinal cord motor neuron inclusions of amyotrophic lateral sclerosis (ALS), Lewy bodies of Parkinson's disease (PD), and Pick's disease neurofilament proteins are aberrantly phosphorylated in the cell bodies. Aberrant phosphorylation of NFs in neurodegeneration is either due to the deregulation of proline directed kinases such as MAPKs and Cdk5 or the downregulation of protein phosphatases such as protein phosphatase 2A (PP2A), calcineurin (PP2B), or both. Recently, studies from our laboratory have shown that peptidyl prolyl isomerase 1 (Pin I) stabilizes the NF phosphorylation in normal and stressed neurons. Pin I selectively binds to the phosphorylated Ser/Thr-Pro residues and converts the cis isomers to the more stable trans isomers. The multiple SP repeats of NF-M/H are stabilized by Pin 1 in a phosphorylation specific manner. Pin I modulates the excitotoxic and oxidative stress induced perikaryal phosphorylation of NF-M/H. Here, we have discussed the factors regulating the topographic phosphorylation of NFs in health and disease.

AB For the last two decades the immunotherapy of patients with solid and hematopoietic tumors has met with variable success. We have reviewed the field of tumor vaccines to examine what has worked and what has not, why this has been the case, how the anti-tumor responses were examined, and how we can make tumor immunity successful for the majority of individuals rather than for the exceptional patients who currently show successful immune responses against their tumors.

AB Background aims. Bone marrow (BM)-derived progenitor cells are under investigation for cardiovascular repair but may be altered by disease. Our aim was to identify differences in gene expression in CD133(+) cells of patients with coronary artery disease (CAD) and healthy controls, and determine whether exercise modifies gene expression. Methods. CD133(+) cells were flow-sorted from 10 CAD patients and four controls, and total RNA was isolated for microarray-based gene expression profiling. Genes that were found to be differentially regulated in patients were analyzed further to investigate whether exercise had any normalizing effect on CD 133(+) cells in CAD patients following 3 months of an exercise program. Results. Improvement in effort tolerance and increases in the number of CD133(+) cells were observed in CAD patients after 3 months of exercise. Gene expression analysis of the CD133(+) cells identified 82 differentially expressed genes (2-fold cut-off, 25% false-discovery rate and % present calls) in patients compared with controls, of which 59 were found to be up-regulated and 23 down-regulated. These genes were found to be involved in carbohydrate metabolism, cell cycle, cellular development and signaling, and molecular transport. Following completion of the exercise program, gene expression patterns resembled those of controls in seven of 10 patients. Conclusions. Alterations in gene expression of BM-derived CD133(+) progenitor cells were found in CAD patients, which in part may be normalized by exercise.

TARGETED RADIOTHERAPY
AB Targeted alpha-particle therapy offers the potential for more specific tumor cell killing with less damage to surrounding normal tissue than beta-emitters because of the combination of short path length (50-80 mu m) with the high linear energy transfer (100 keV mu m(-1)) of this emission. These physical properties offer the real possibility of targeted (pre-targeted) alpha-therapy suitable for the elimination of minimal residual or micrometastatic disease. Targeted and pre-targeted radioimmunotherapy (RIT) using alpha-emitters such as Bi-212 (T-1/2 = 1.01 h) and Pb-212 (T-1/2 = 10.6 h) has demonstrated significant utility in both in vitro and in vivo model systems. Pb-212, a promising alpha-particle emitting source, is the longer-lived parent nuclide of Bi-212, and serves as an in vivo generator of Bi-212. The radionuclide has been successfully used in RIT and pre-targeted RIT and demonstrated an enhanced therapeutic efficacy in combination with chemotherapeutics, such as gemcitabine and paclitaxel. The following perspective addresses the modes of radionuclide production, radiolabelling and chelation chemistry, as well as the application of Pb-212 to targeted and pre-targeted radiation therapy.

AB Metallic radionuclides are the mainstay of both diagnostic and therapeutic radiopharmaceuticals. Therapeutic nuclear medicine is less advanced but has tremendous potential if the radionuclide is accurately targeted. Great interest exists in the field of inorganic chemistry for developing target specific radiopharmaceuticals based on radiometals for non-invasive disease detection and cancer radiotherapy. This perspective will focus on the nuclear properties of a few important radiometals and their recent applications to developing radiopharmaceuticals for imaging and therapy. Other topics for discussion will include imaging techniques, radiotherapy, analytical techniques, and radiation safety. The ultimate goal of this perspective is to introduce inorganic chemists to the field of nuclear medicine and radiopharmaceutical development, where many applications of fundamental inorganic chemistry can be found.

AB The past decade has witnessed the modern advances of high-throughput technology and rapid growth of research capacity in producing large-scale biological data, both of which were concomitant with an exponential growth of biomedical literature. This wealth of scholarly knowledge is of significant importance for researchers in making scientific discoveries and healthcare professionals in managing health-related matters. However, the acquisition of such information is becoming increasingly difficult due to its large volume and rapid growth. In response, the National Center for Biotechnology Information (NCBI) is continuously making changes to its PubMed Web service for improvement. Meanwhile, different entities have devoted themselves to developing Web tools for helping users quickly and efficiently search and retrieve relevant publications. These practices, together with maturity in the field of text mining, have led to an increase in the number and quality of various Web tools that provide comparable literature search service to PubMed. In this study, we review 28 such tools, highlight their respective innovations, compare them to the PubMed system and one another, and discuss directions for future development. Furthermore, we have built a website dedicated to tracking existing systems and future advances in the field of biomedical literature search. Taken together, our work serves information seekers in choosing tools for their needs and service providers and developers in keeping current in the field.

AB Eukaryotic chromatin is composed of DNA and protein components-core histones-that act to compactly pack the DNA into nucleosomes, the fundamental building blocks of chromatin. These nucleosomes are connected to adjacent nucleosomes by linker histones. Nucleosomes are highly dynamic and, through various core histone post-translational modifications and incorporation of diverse histone variants, can serve as epigenetic marks to control processes such as gene expression and recombination. The Histone Sequence Database is a curated collection of sequences and structures of histones and non-histone proteins containing histone folds, assembled from major public databases. Here, we report a substantial increase in the number of sequences and taxonomic coverage for histone and histone fold-containing proteins available in the database. Additionally, the database now contains an expanded dataset that includes archaeal histone sequences. The database also provides comprehensive multiple sequence alignments for each of the four core histones (H2A, H2B, H3 and H4), the linker histones (H1/H5) and the archaeal histones. The database also includes current information on solved histone fold-containing structures. The Histone Sequence Database is an inclusive resource for the analysis of chromatin structure and function focused on histones and histone fold-containing proteins. Database URL: The Histone Sequence Database is freely available and can be accessed at http://research.nhgri.nih.gov/histones/.

AB New generation sequencing technologies have resulted in significant increases in the number of complete genomes. Functional characterization of these genomes, such as by high-throughput proteomics, is an important but challenging task due to the difficulty of scaling up existing experimental techniques. By use of comparative genomics techniques, experimental results can be transferred from one genome to another, while at the same time minimizing errors by requiring discovery in multiple genomes. In this study, protein phosphorylation, an essential component of many cellular processes, is studied using data from large-scale proteomics analyses of the phosphoproteome. Phosphorylation sites from Homo sapiens, Mus musculus and Drosophila melanogaster phosphopeptide data sets were mapped onto conserved domains in NCBI's manually curated portion of Conserved Domain Database (CDD). In this subset, 25 phosphorylation sites are found to be evolutionarily conserved between the three species studied. Transfer of phosphorylation annotation of these conserved sites onto sequences sharing the same conserved domains yield 3253 phosphosite annotations for proteins from coelomata, the taxonomic division that spans H. sapiens, M. musculus and D. melanogaster. The method scales automatically, so as the amount of experimental phosphoproteomics data increases, more conserved phosphorylation sites may be revealed.

TI ppiTrim: constructing non-redundant and up-to-date interactomes

AB Robust advances in interactome analysis demand comprehensive, non-redundant and consistently annotated data sets. By non-redundant, we mean that the accounting of evidence for every interaction should be faithful: each independent experimental support is counted exactly once, no more, no less. While many interactions are shared among public repositories, none of them contains the complete known interactome for any model organism. In addition, the annotations of the same experimental result by different repositories often disagree. This brings up the issue of which annotation to keep while consolidating evidences that are the same. The iRefIndex database, including interactions from most popular repositories with a standardized protein nomenclature, represents a significant advance in all aspects, especially in comprehensiveness. However, iRefIndex aims to maintain all information/annotation from original sources and requires users to perform additional processing to fully achieve the aforementioned goals. Another issue has to do with protein complexes. Some databases represent experimentally observed complexes as interactions with more than two participants, while others expand them into binary interactions using spoke or matrix model. To avoid untested interaction information buildup, it is preferable to replace the expanded protein complexes, either from spoke or matrix models, with a flat list of complex members.
To address these issues and to achieve our goals, we have developed ppiTrim, a script that processes iRefIndex to produce non-redundant, consistently annotated data sets of physical interactions. Our script proceeds in three stages: mapping all interactants to gene identifiers and removing all undesired raw interactions, deflating potentially expanded complexes, and reconciling for each interaction the annotation labels among different source databases. As an illustration, we have processed the three largest organismal data sets: yeast, human and fruitfly. While ppiTrim can resolve most apparent conflicts between different labelings, we also discovered some unresolvable disagreements mostly resulting from different annotation policies among repositories.

AB The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Central Repository makes data and biospecimens from NIDDK-funded research available to the broader scientific community. It thereby facilitates: the testing of new hypotheses without new data or biospecimen collection; pooling data across several studies to increase statistical power; and informative genetic analyses using the Repository's well-curated phenotypic data. This article describes the initial database plan for the Repository and its revision using a simpler model. Among the lessons learned were the trade-offs between the complexity of a database design and the costs in time and money of implementation; the importance of integrating consent documents into the basic design; the crucial need for linkage files that associate biospecimen IDs with the masked subject IDs used in deposited data sets; and the importance of standardized procedures to test the integrity data sets prior to distribution. The Repository is currently tracking 111 ongoing NIDDK-funded studies many of which include genotype data, and it houses over 5 million biospecimens of more than 25 types including serum, plasma, stool, urine, DNA, red blood cells, buffy coat and tissue. Repository resources have supported a range of biochemical, clinical, statistical and genetic research (188 external requests for clinical data and 31 for biospecimens have been approved or are pending). Genetic research has included GWAS, validation studies, development of methods to improve statistical power of GWAS and testing of new statistical methods for genetic research. We anticipate that the future impact of the Repository's resources on biomedical research will be enhanced by (i) cross-listing of Repository biospecimens in additional searchable databases and biobank catalogs; (ii) ongoing deployment of new applications for querying the contents of the Repository; and (iii) increased harmonization of procedures, data collection strategies, questionnaires etc. across both research studies and within the vocabularies used by different repositories.

AB The inner ear structure of Antimora rostrata and its coupling to the swim bladder were analyzed and compared with the inner ears of several shallow-water species that also have similar coupling. The inner ear of Antimora has a long saccular otolith and sensory epithelium as compared to many other fishes. Some parts of the membranous labyrinth are thick and rigid, while other parts are thinner but attached tightly to the bony capsule. The partially rigid membranous labyrinth, along with its intimate connection to the swim bladder, may help the inner ear follow the sound oscillations from the swim bladder with better precision than would occur in a less rigid inner ear. In addition, the saccular sensory epithelium has an elaborate structure and an anterior enlargement that may be correlated with increased hearing sensitivity. Some of the features in the inner ear of Antimora may reflect the functional specialization of deep-water living and support the hypothesis that there is enhanced inner ear sensitivity in some deep-sea fishes.

AB Anxious individuals exhibit threat biases at multiple levels of information processing. From a developmental perspective, abnormal safety learning in childhood may establish threat-related appraisal biases early, which may contribute to chronic disorders in adulthood. This review illustrates how the interface among attention, threat appraisal, and fear learning can generate novel insights for outcome prediction. This review summarizes data on amygdala function, as it relates to learning and attention, highlights the importance of examining threat appraisal, and introduces a novel imaging paradigm to investigate the neural correlates of threat appraisal and threat-sensitivity during extinction recall. This novel paradigm can be used to investigate key questions relevant to prognosis and treatment. Depression and Anxiety 28:5-17, 2011. (C) 2010 Wiley-Liss, Inc.

AB Background: Although numerous studies have examined the role of latent predispositions to internalizing and externalizing disorders in the structure of comorbidity among common mental disorders, none examined latent predispositions in predicting development of comorbidity. Methods: A novel method was used to study the role of latent variables in the development of comorbidity among lifetime DSM-IV disorders in the National Comorbidity Surveys. Broad preliminary findings are briefly presented to describe the method. The method used survival analysis to estimate time-lagged associations among 18 lifetime DSM-IV anxiety, mood, behavior, and substance disorders. A novel estimation approach examined the extent to which these predictive associations could be explained by latent canonical variables representing internalizing and externalizing disorders. Results: Consistently significant positive associations were found between temporally primary and secondary disorders. Within-domain time-lagged associations were generally stronger than between-domain associations. The vast majority of associations were explained by a model that assumed mediating effects of latent internalizing and externalizing variables, although the complexity of this model differed across samples. A number intriguing residual associations emerged that warrant further investigation. Conclusions: The good fit of the canonical model suggests that common causal pathways account for most comorbidity among the disorders considered. These common pathways should be the focus of future research on the development of comorbidity. However, the existence of several important residual associations shows that more is involved than simple mediation. The method developed to carry out these analyses provides a unique way to pinpoint these significant residual associations for subsequent focused study.

AB Anxiety disorders are thought to be one of the most common psychiatric diagnoses in children/adolescents. Chronic medical illness is a significant risk factor for the development of an anxiety disorder, and the prevalence rate of anxiety disorders among youths with chronic medical illnesses is higher compared to their healthy counterparts. Anxiety disorders may develop secondary to predisposing biological mechanisms related to a child's specific medical illness, as a response to being ill or in the hospital, a threatening environment, as a result of other genetic and psychological factors, or as a combination of all these factors. Additionally, exposure to physical pain early in one's life and/or frequent painful medical procedures are correlated with fear and anxiety during subsequent procedures and treatments, and may lead to medical nonadherence and other comorbidities. Anxiety disorders can have serious consequences in children/adolescents with chronic and/or life-limiting medical illnesses. Therefore, proper identification and treatment of anxiety disorders is necessary and may improve not only psychiatric symptoms but also physical symptoms. Behavioral and cognitive methods as well as psychotropic medications are used to treat anxiety disorders in pediatric patients. We will review current treatments for anxiety in children/adolescents with medical illnesses and propose future research directions. Depression and Anxiety 28:40-49, 2011. (C) 2010 Wiley-Liss, Inc.

TI Enhanced right amygdala activity in adolescents during encoding of
positively valenced pictures
SO DEVELOPMENTAL COGNITIVE NEUROSCIENCE
LA English

DE Adolescents; Adults; Encoding; Positive stimuli; Amygdala; Hippocampus
AB While studies among adults implicate the amygdala and interconnecting brain regions in encoding emotional stimuli, few studies have examined whether developmental changes occur within this emotional-memory network during adolescence. The present study examined whether adolescents and adults differentially engaged the amygdala and hippocampus during successful encoding of emotional pictures, with either positive or negative valence. Eighteen adults and twelve adolescents underwent event-related fMRI while encoding emotional pictures. Approximately 30 min later, outside the scanner, subjects were asked to recall the pictures seen during the scan. Age group differences in brain activity in the amygdala and hippocampus during encoding of the pictures that were later successfully and unsuccessfully recalled were separately compared for the positive and negative pictures. Adolescents, relative to adults, demonstrated enhanced activity in the right amygdala during encoding of positive pictures that were later recalled compared to not recalled. There were no age group differences in amygdala or hippocampal activity during successful encoding of negative pictures. The findings of preferential activity within the adolescent right amygdala during successful encoding of positive pictures may have implications for the increased reward and novelty seeking behavior, as well as elevated rates of psychopathology, observed during this distinct developmental period.

AB We compared neural and behavioral responses to feedback received during interpersonal interactions within the Prisoner's Dilemma game between adolescents with anxiety disorders (n = 12) and healthy peers (n = 17). Groups differed significantly in neural activation in the medial prefrontal cortex (mPFC), anterior cingulate cortex (ACC), precuneus, insula, and temporoparietal junction (TPJ). Anxious adolescents were also more likely than controls to cooperate after co-player betrayal. Our findings provide evidence that social behavior and related neural activity differs between anxious and healthy adolescents. These findings constitute a step toward elucidating neural correlates of social impairment in anxious youths.

AB Hormonal imbalances during development may have long-lasting effects. Using functional magnetic resonance imaging (fMRI), we compared 14 youths with Congenital Adrenal Hyperplasia (CAH), a genetic disorder of hormonal dysfunction, with 22 healthy controls on memory encoding of emotional faces. Patients remembered fewer faces than controls, particularly fearful faces. FMRI data to successfully encoded fearful faces revealed that males with CAH showed significant activations in amygdala, hippocampus, and anterior cingulate relative to unaffected males, while females with CAH demonstrated deactivations relative to unaffected females in these regions. Findings indicate that steroid abnormalities during development can have important effects on neural correlates of emotional memory.

TI Magnitude of [C-11]PK11195 Binding Is Related to Severity of Motor
Deficits in a Rabbit Model of Cerebral Palsy Induced by Intrauterine
Endotoxin Exposure

AB Intrauterine inflammation is known to be a risk factor for the development of periventricular leukomalacia (PVL) and cerebral palsy. In recent years, activated microglial cells have been implicated in the pathogenesis of PVL and in the development of white matter injury. Clinical studies have shown the increased presence of activated microglial cells diffusely throughout the white matter in brains of patients with PVL. In vitro studies have reported that activated microglial cells induce oligodendrocyte damage and white matter injury by release of inflammatory cytokines, reactive nitrogen and oxygen species and the production of excitotoxic metabolites. PK11195 [1-(2-chlorophenyl)-N-methyl-N-(1-methylpropyl)-3-isoquinoline carboxamide] is a ligand that is selective for the 18-kDa translocator protein expressed on the outer mitochondrial membrane of activated microglia and macrophages. When labeled with carbon-11, [C-11]PK11195 can effectively be used as a ligand in positron emission tomography (PET) studies for the detection of activated microglial cells in various neuroinflammatory and neurodegenerative conditions. In this study, we hypothesized that the magnitude of [C-11]-(R)-PK11195 uptake in the newborn rabbit brain, as measured using a small-animal PET scanner, would match the severity of motor deficits resulting from intrauterine inflammation-induced perinatal brain injury. Pregnant New Zealand white rabbits were intrauterinely injected with endotoxin or saline at 28 days of gestation. Kits were born spontaneously at 31 days and underwent neurobehavioral testing and PET imaging following intravenous injection of the tracer [C-11]-(R)-PK11195 on the day of birth. The neurobehavioral scores were compared with the change in [C-11]PK11195 uptake over the time of scanning, for each of the kits. Upon analysis using receiver operating characteristic curves, an optimal combined sensitivity and specificity for detecting abnormal neurobehavioral scores suggestive of cerebral palsy in the neonatal rabbit was noted for a positive change in [C-11]PK11195 uptake in the brain over time on PET imaging (sensitivity of 100% and area under the curve of >0.82 for all parameters tested). The strongest agreements were noted between a positive uptake slope - indicating increased [C-11]PK11195 uptake over time - and worsening scores for measures of locomotion (indicated by hindlimb movement, forelimb movement, circular motion and straightline motion; Cohen's kappa >0.75 for each) and feeding (indicated by ability to suck and swallow and turn the head during feeding; Cohen's kappa >0.85 for each). This was also associated with increased numbers of activated microglia (mean ratio 8 +/- SD of activated to total microglia: 0.96 +/- 0.16 in the endotoxin group vs. 0.13 +/- 0.08 in controls; p < 0.001) in the internal capsule and corona radiata. Our findings indicate that the magnitude of [C-11]PK11195 binding measured in vivo by PET imaging matches the severity of motor deficits in the neonatal rabbit. Molecular imaging of ongoing neuroinflammation in the neonatal period may be helpful as a screening biomarker for detecting patients at risk of developing cerebral palsy due to a perinatal insult.

AB This neuroimaging study examines the development of cognitive flexibility using the Change task in a sample of youths and adults. The Change task requires subjects to inhibit a prepotent response and substitute an alternative response, and the task incorporates an algorithm that adjusts task difficulty in response to subject performance. Data from both groups combined show a network of prefrontal and parietal areas that are active during the task. For adults vs. youths, a distributed network was more active for successful change trials versus go, baseline, or unsuccessful change trials. This network included areas involved in rule representation, retrieval (lateral PFC), and switching (medial PFC and parietal regions). These results are consistent with data from previous task-switching experiments and inform developmental understandings of cognitive flexibility.

AB OBJECTIVE The nuclear receptor TAK1/TR4/NR2C2 is expressed in several tissues that are important in the control of energy homeostasis. In this study, we investigate whether TAK1 functions as a regulator of lipid and energy homeostasis and has a role in metabolic syndrome.
RESEARCH DESIGN AND METHODS We generated TAK1-deficient (TAK1(-/-)) mice to study the function of TAK1 in the development of metabolic syndrome in aged mice and mice fed a high-fat diet (HFD). (Immuno)histochemical, biochemical, and gene expression profile analyses were performed to determine the effect of the loss of TAK1 expression on lipid homeostasis in liver and adipose tissues. In addition, insulin sensitivity, energy expenditure, and adipose-associated inflammation were compared in wild-type (WT) and TAK1(-/-) mice fed a HFD.
RESULTS TAK1-deficient (TAK1(-/-)) mice are resistant to the development of age- and HFD-induced metabolic syndrome. Histo- and biochemical analyses showed significantly lower hepatic triglyceride levels and reduced lipid accumulation in adipose tissue in TAK1(-/-) mice compared with WT mice. Gene expression profiling analysis revealed that the expression of several genes encoding proteins involved in lipid uptake and triglyceride synthesis and storage, including Cidea, Cidec, Mogatl, and CD36, was greatly decreased in the liver and primary hepatocytes of TAK1(-/-) mice. Restoration of TAK1 expression in TAK1(-/-) hepatocytes induced expression of several lipogenic genes. Moreover, TAK1(-/-) mice exhibited reduced infiltration of inflammatory cells and expression of inflammatory genes in white adipose tissue, and were resistant to the development of glucose intolerance and insulin resistance. TAK1(-/-) mice consume more oxygen and produce more carbon dioxide than WT mice, suggesting increased energy expenditure.
CONCLUSIONS Our data reveal that TAK1 plays a critical role in the regulation of energy and lipid homeostasis, and promotes the development of metabolic syndrome. TAK1 may provide a new therapeutic target in the management of obesity, diabetes, and liver steatosis. Diabetes 60:177-188, 2011

RESEARCH DESIGN AND METHODS- We prospectively examined supplemental use of multivitamins and individual vitamins and minerals assessed in 1995-1996 in relation to self-reported diabetes diagnosed after 2000 among 232,007 participants in the National Institutes of Health American Association of Retired Persons Diet and Health Study. Multivitamin use was assessed by a food-frequency questionnaire at baseline. Odds ratios (ORs) and 95% CIs were calculated by logistic regression models, adjusted for potential confounders. In total, 14,130 cases of diabetes diagnosed after 2000 were included in the analysis.
RESULTS- Frequent use of any multivitamins was not associated with risk of diabetes after adjustment for potential confounders and uses of individual supplements. Compared with nonusers of any multivitamins, the multivariate ORs among users were 1.07 (95% CI 0.94-1.21) for taking vitamins less than once per week, 0.97 (0.88-1.06) for one to three times per week, 0.92 (0.84-1.00) for four to six times per week, and 1.02 (0.98-1.06) for seven or more times per week (P for trend = 0.64). Significantly lower risk of diabetes was associated with the use of vitamin C or calcium supplements. The multivariate ORs comparing daily users with nonusers were 0.91 (0.86-0.97) for vitamin C supplements and 0.85 (0.80-0.90) for calcium supplements. Use of vitamin E or other individual vitamin and mineral supplements were not associated with diabetes risk.
CONCLUSIONS- In this large cohort of U.S. older adults, multivitamin use was not associated with diabetes risk. The findings of lower diabetes risk among frequent users of vitamin C or calcium supplements warrant further evaluations.

LA English
DT Article
ID ASSOCIATION ANALYSIS; SUSCEPTIBILITY LOCI; VARIANTS; MELLITUS
AB OBJECTIVE- To test if knowledge of type 2 diabetes genetic variants improves disease prediction.
RESEARCH DESIGN AND METHODS- We tested 40 single nucleotide polymorphisms (SNPs) associated with diabetes in 3,471 Framingham Offspring Study subjects followed over 34 years using pooled logistic regression models stratified by age (<50 years, diabetes cases = 144; or >= 50 years, diabetes cases = 302). Models included clinical risk factors and a 40-SNP weighted genetic risk score.
RESULTS- In people <50 years of age, the clinical risk factors model C-statistic was 0.908; the 40-SNP score increased it to 0.911 (P = 0.3; net reclassification improvement (NRI): 10.2%, P = 0.001). In people >= 50 years of age, the C-statistics without and with the score were 0.883 and 0.884 (P = 0.2; NRI: 0.4%). The risk per risk allele was higher in people <50 than >= 50 years of age (24 vs. 11%; P value for age interaction = 0.02).
CONCLUSIONS- Knowledge of common genetic variation appropriately reclassifies younger people for type 2 diabetes risk beyond clinical risk factors but not older people.

TI Physical Activity Before and During Pregnancy and Risk of Gestational
Diabetes Mellitus A meta-analysis
SO DIABETES CARE

HETEROGENEITY; MUSCLE; BIAS
AB OBJECTIVE- Gestational diabetes mellitus (GDM) is one of the most common complications of pregnancy and is associated with a substantially elevated risk of adverse health outcomes for both mothers and offspring. Physical activity may contribute to the prevention of GDM and thus is crucial for dissecting the vicious circle involving GDM, childhood obesity, and adulthood obesity, and diabetes. Therefore, we aimed to systematically review and synthesize the current evidence on the relation between physical activity and the development of GDM.
RESEARCH DESIGN AND METHODS- Medline, EMBASE, and Cochrane Reviews were searched from inception to 31 March 2010. Studies assessing the relationship between physical activity and subsequent development of GDM were included. Characteristics including study design, country, GDM diagnostic criteria, ascertainment of physical activity, timing of exposure (prepregnancy or early pregnancy), adjusted relative risks, CIs, and statistical methods were extracted independently by two reviewers.
RESULTS- Our search identified seven prepregnancy and five early pregnancy studies, including five prospective cohorts, two retrospective case-control studies, and two cross-sectional study designs. Prepregnancy physical activity was assessed in 34,929 total participants, which included 2,813 cases of GDM, giving a pooled odds ratio (OR) of 0.45 (95% CI 0.28-0.75) when the highest versus lowest categories were compared. Exercise in early pregnancy was assessed in 4,401 total participants, which included 361 cases of GDM, and was also significantly protective (0.76 [95% CI 0.70-0.83]).
CONCLUSIONS Higher levels of physical activity before pregnancy or in early pregnancy are associated with a significantly lower risk of developing GDM.

AB Aims/hypothesis The ability to measure insulin sensitivity across the phenotypic spectrum of diabetes may contribute to a more accurate characterisation of diabetes type. Our goal was to develop and validate an insulin sensitivity (IS) score using the euglycaemic-hyperinsulinaemic clamp in a subset (n = 85) of 12- to 19-year-old youths with diabetes participating in the SEARCH study in Colorado, USA.
Methods Youths with a diagnosis of type 1 (n = 60) or type 2 diabetes (n = 25) underwent a 3 h clamp to measure glucose disposal rate (GDR, mg kg(-1) min(-1)). Demographic (age, sex, race), clinical (BMI, waist, Tanner stage) and metabolic characteristics (HbA(1c), lipids, blood pressure, urine albumin: creatinine) were used to estimate log(e)IS score via stepwise linear regression on a model-development set (n = 53). Estimated IS score was evaluated for reproducibility on two validation sets: youths with diabetes (n = 33) and healthy control youths (n = 22).
Results The best model included waist, triacylglycerol (TG) and HbA(1c) levels (R-2 = 0.74). Diabetes type did not enter the model and there were no significant interactions between diabetes type and other predictors. Estimated IS score correlated well (r = 0.65, p < 0.0001; r = 0.62, p = 0.002) with GDR on the two validation sets. Based on this analysis, we propose the following formula to estimate insulin sensitivity in youths with diabetes: logeIS 4: 64725 = 0: 02032 (waist; cm) = 0: 09779 (HbA(1c), %) - 0: 00235 (TG; mg/dl; to convert TG values from mmol/l to mg/dl; divide by 0.0113).
Conclusions/interpretation Insulin sensitivity can be estimated in adolescents with diabetes using routinely collected measures. This score can be applied to epidemiological studies of youths with diabetes to characterise relationships between dimensions of diabetes type.

AB Aims/hypothesis Rare mutations in the gene HNF4A, encoding the transcription factor hepatocyte nuclear factor 4 alpha (HNF-4A), account for similar to 5% of cases of MODY and more frequent variants in this gene may be involved in multifactorial forms of diabetes. Two low-frequency, non-synonymous variants in HNF4A (V255M, minor allele frequency [MAF] similar to 0.1%; T130I, MAF similar to 3.0%)-known to influence downstream HNF-4A target gene expression-are of interest, but previous type 2 diabetes association reports were inconclusive. We aimed to evaluate the contribution of these variants to type 2 diabetes susceptibility through large-scale association analysis.
Methods We genotyped both variants in at least 5,745 cases and 14,756 population controls from the UK and Denmark. We also undertook an expanded association analysis that included previously reported and novel genotype data obtained in Danish, Finnish, Canadian and Swedish samples. A meta-analysis incorporating all published association studies of the T130I variant was subsequently carried out in a maximum sample size of 14,279 cases and 26,835 controls.
Results We found no association between V255M and type 2 diabetes in either the initial (p = 0.28) or the expanded analysis (p = 0.44). However, T130I demonstrated a modest association with type 2 diabetes in the UK and Danish samples (additive per allele OR 1.17 [95% CI 1.08-1.28]; p = 1.5 x 10(-4)), which was strengthened in the meta-analysis (OR 1.20 [95% CI 1.10-1.30]; p = 2.1 x 10(-5)).
Conclusions Our data are consistent with T130I as a low-frequency variant influencing type 2 diabetes risk, but are not conclusive when judged against stringent standards for genome-wide significance. This study exemplifies the difficulties encountered in association testing of low-frequency variants.

AB Background Some patients with Zollinger-Ellison syndrome post curative gastrinoma resection continue to show gastric acid hypersecretion; however, the mechanism is unknown.
Aim The aim of this study was to prospectively study acid secretion following curative gastrinoma resection and analyze factors contributing in patients with Zollinger-Ellison syndrome.
Methods Fifty patients cured post gastrinoma resection were studied with serial assessments of acid secretory status, cure status and ECL-cell status/activity (with serial biopsies, CgA, urinary N-MIAA). Correlative analysis was performed to determine predictive factors.
Results Hypersecretion occurred in 31 patients (62%) and 14 had extreme-hypersecretion. There was an initial decline (3-6 months) in BAO/MAO, which then remained stable for eight years. Preoperative BAO correlated with the postoperative secretion, but not other clinical, tumoral, laboratory variables, the degree of postoperative acid suppression or type of antisecretory drug needed. Hypersecretors had greater postoperative ECL changes (P = 0.005), serum CGA (P = 0.009) and 24-h urinary N-MIAA (P = 0.0038).
Conclusions Post curative resection, gastric hypersecretion persists long term (mean 8 years) in 62% of patients and in 28% it is extreme, despite normogastrinemia. No preoperative variable except BAO correlates with postresection hypersecretion. The persistent increased ECL-cell extent post curative resection suggests prolonged hypergastrinemia can lead to changes in ECL-cells that are either irreversible in humans or sustained by unknown mechanisms not involving fasting hypergastrinemia and which can result in hypersecretion, in a proportion of which it can be extreme. Whether similar findings may occur in patients with idiopathic GERD treated for prolonged periods (>10 years) with PPIs, at present, is unknown.

TI History at the intersection of disability and public health: The case of
John Galsworthy and disabled soldiers of the First World War
SO DISABILITY AND HEALTH JOURNAL
LA English
DT Article
DE History; War; Rehabilitation; Disabled veterans
AB The author presented an earlier version of this historical article to the Disability Section of the American Public Health Association (November 2009). It is part of his ongoing research in the social and cultural history of medicine as the field intersects with the history of disability, veterans, and public health, as well as current issues that touch all of these areas. This article introduces readers to perspectives on disability held by the British novelist John Galsworthy (1867-1933), which he developed primarily through his philanthropic support for and his compositions about rehabilitation programs for British and American soldiers disabled in the First World War (1914-1918). Readers will learn that Galsworthy's perspectives are as much about his identity as an individual with disabilities as they are about men disabled in the "war to end all wars." The rediscovery of Galsworthy's experiences and words more than 90 years after the end of World War I reveals how history is present today at the intersection of disability and public health. Indeed, the story of Galsworthy ultimately seeking to forget his own experiences during the "Great War," as well as the very physical and psychological disability caused by that conflict, can inspire public health professionals and disability rights advocates today to remember-indeed, to advocate for-men and women who served in battle and have returned home to realize renewed health and social participation despite permanent physical and psychological wounds. Readers will note that language used throughout this article to describe disability is period-specific and therefore not keeping with current conventions. Published by Elsevier Inc.

AB Meckel-Gruber syndrome (MKS) is a recessive disorder resulting in multiple birth defects that are associated with mutations affecting ciliogenesis. We recovered a mouse mutant with a mutation in the Mks1 gene (Mks1(del64-323)) that caused a 260-amino-acid deletion spanning nine amino acids in the B9 domain, a protein motif with unknown function conserved in two other basal body proteins. We showed that, in wild-type cells, Mks1 was localized to the mother centriole from which the cilium was generated. However, in mutant Mks1(del64-323) cells, Mks1 was not localized to the centriole, even though it maintained a punctate distribution. Resembling MKS patients, Mks1 mutants had craniofacial defects, polydactyly, congenital heart defects, polycystic kidneys and randomized left-right patterning. These defects reflected disturbance of functions subserved by motile and nonmotile cilia. In the kidney, glomerular and tubule cysts were observed along with short cilia, and cilia were reduced in number to a near-complete loss. Underlying the left-right patterning defects were fewer and shorter nodal cilia, and analysis with fluorescent beads showed no directional flow at the embryonic node. In the cochlea, the stereocilia were mal-patterned, with the kinocilia being abnormally positioned. Together, these defects suggested disruption of planar cell polarity, which is known to regulate node, kidney and cochlea development. In addition, we also showed that Shh signaling was disrupted. Thus, in the neural tube, the floor plate was not specified posteriorly even as expression of the Shh mediator Gli2 increased. By contrast, the Shh signaling domain was expanded in the anterior neural tube and anterior limb bud, consistent with reduced Gli3-repressor (Gli3R) function. The latter probably accounted for the preaxial digit duplication exhibited by the Mks1(del64-323) mutants. Overall, these findings indicate that centriole localization of Mks1 is required for ciliogenesis of motile and non-motile cilia, but not for centriole assembly. On the basis of these results, we hypothesize a role for the B9 domain in mother centriole targeting, a possibility that warrants further future investigations.

AB Measurement of DNA double-strand break (DSB) levels in cells is useful in many research areas, including those related to DNA damage and repair, tumorigenesis, anti-cancer drug development, apoptosis, radiobiology, environmental effects, and aging, as well as in the clinic. DSBs can be detected in the nuclei of cultured cells and tissues with an antibody to H2AX phosphorylated on serine residue 139 (gamma-H2AX). DSB levels can be obtained either by measuring overall gamma-H2AX protein levels in a cell population or by counting gamma-H2AX foci in individual nuclei. Total levels can be obtained in extracts of cell populations by immunoblot analysis, and in cell populations by flow cytometry. Furthermore, with flow cytometry, the cell cycle distribution of a population can be obtained in addition to DSB levels, which is an advantage when studying anti-cancer drugs targeting replicating tumor cells. These described methods are used in genotoxicity assays of compounds of interest or in analyzing DSB repair after exposure to drugs or radiation. Immunocyto/immunohistochemical analysis can detect gamma-H2AX foci in individual cells and is very sensitive (a single DSB can be visualized), permitting the use of extremely small samples. Measurements of gamma-H2AX focal numbers can reveal subtle changes found in the radiation-induced tissue bystander response, low dose radiation exposure, and in cells with mutations in genomic stability maintenance pathways. In addition, marking DNA DSBs in a nucleus with gamma-H2AX is a powerful tool to identify novel DNA repair proteins by their abilities to co-localize with gamma-H2AX foci at the DSB site. This chapter presents techniques for gamma-H2AX detection in a variety of human and mouse samples.

AB Resection of DNA double-strand break (DSB) ends, which results in 3' single-stranded tails, is an early event of DSB repair and can be a critical determinant in choice of repair pathways and eventual genome stability. Current techniques for examining resection are restricted to model in vivo systems with defined substrates (i.e., HO-endonuclease targets). We present here a robust assay that can analyze not only the resection of site-specific DSBs which typically have "clean" double-strand ends but also random "dirty-ended" DSBs such as those generated by ionizing radiation and chemotherapeutic agents. The assay is based on our finding that yeast chromosomes with single-stranded DNA tails caused by resection are less mobile during pulsed-field gel electrophoresis (PFGE) than those without a tail. In combination with the use of a circular chromosome and enzymatic trimming of single-stranded DNA, resection of random DSBs can be easily detected and analyzed. This mobility-shift assay provides a unique opportunity to examine the mechanisms of resection, early events in DSB repair, as well as factors involved in pathway regulation.

However, animals treated with progressively increasing doses of METH over several weeks are protected against the toxic effects of the drug. In the present study, we tested the possibility that this pattern of METH injections might be associated with transcriptional changes in the rat striatum, an area of the brain which is known to be very sensitive to METH toxicity and which is protected by METH preconditioning. We found that the presence and absence of preconditioning followed by injection of large doses of METH caused differential expression in different sets of striatal genes. Quantitative PCR confirmed METH-induced changes in some genes of interest. These include small heat shock 27 kD proteins 1 and 2 (HspB1 and HspB2), brain derived neurotrophic factor (BDNF), and heme oxygenase-1 (Hmox-1). Our observations are consistent with previous studies which have reported that ischemic or pharmacological preconditioning can cause reprogramming of gene expression after lethal ischemic insults. These studies add to the growing literature on the effects of preconditioning on the brain transcriptome.

AB Over 15 million people in the United States report using complementary and alternative medications (CAM). Patients with HIV infection represent an important segment of this population. Because of their ability to modulate a variety of cytochrome P450 (CYP) enzymes and drug transport proteins such as P-glycoprotein (P-gp), a number of herbs have been shown to interact with coadministered medications. Unfortunately, in vitro microsomal studies often fail to predict results obtained in humans. The herb associated with the greatest number of drug interactions in humans is St. John's wort (Hypericum perforatum). As a potent inducer of CYP and P-gp, St. John's wort has been shown to reduce the plasma concentrations of certain coadministered medications by >50%. Other herbs have been shown to induce the metabolism of coadministered medications as well. However, the magnitude of these interactions is markedly less than that produced by St. John's wort. Nonetheless, even mild herb-drug interactions may be clinically relevant for coadministered medications with narrow therapeutic indices. To this end, the need for rigorous studies to identify potentially significant herb-drug interactions continues. Clinicians caring for patients taking CAM therapy should maintain a high degree of suspicion for herb-drug interactions in the face of unexplained toxicity or loss of efficacy, and be familiar with resources that can help manage or avoid herb-drug interactions.

AB The pregnane X receptor (PXR) binds xenobiotics and regulates the expression of several drug-metabolizing enzymes and transporters. Human PXR (hPXR) activation and CYP3A4 induction can be involved in drug-drug interactions, resulting in reduced efficacy or increased toxicity. However, there are known species-specific differences with regard to PXR activation that should be taken into account when animal PXR data are extrapolated to humans. We profiled 2816 clinically used drugs from the National Institutes of Health Chemical Genomics Center Pharmaceutical Collection for their ability to activate hPXR and rat PXR (rPXR) at the cellular level, induce human CYP3A4 at the cellular level, and bind human PXR at the protein level. From 6 to 11% of drugs were identified as active across the four assays, which included assay-specific and pan-active compounds. The lowest concordance was observed between the hPXR and rPXR assays, and many compounds active in both assays nonetheless demonstrated significant potency differences between species. Analysis based on clustering potency values demonstrated the greatest activity correlation between the hPXR activation and CYP3A4 induction assays. Structure-activity relationship analysis identified chemical scaffolds that were pan-active (e.g., dihydropyridine calcium channel blockers) and others that were uniquely active in individual assays (e.g., steroids and fatty acids). These results provide important information on PXR activation by clinically used drugs, highlight the species specificity of PXR activation by xenobiotics, and provide a means of prioritizing compounds for follow-up studies and optimization efforts.

AB Discovered in 1980 by the late Robert F. Furchgott, endothelium-derived relaxing factor, nitric oxide (NO), has been in the forefront of vascular research for several decades. What was originally a narrow approach, has been significantly widened due to major advances in understanding the chemical and biological properties of NO as well as its signaling pathways and discovering new sources of this notorious free radical gas. In this review, recent discoveries regarding NO and their implications on therapy for delayed cerebral vasospasm are presented.

AB Reduced intra- and perivascular availability of nitric oxide (NO) significantly contributes to the multifactorial pathophysiology of cerebral vasospasm after aneurysmal subarachnoid hemorrhage (SAH). The short half-life of NO demands its therapeutic substitution via NO donors. Classic NO donors such as sodium nitroprusside and nitroglycerin cannot be used as routine therapeutics because of serious side effects. Thus, a new generation of NO donors has been the subject of experimental investigations to avoid the drawbacks of the classic drugs. The purpose of this paper is to review the characteristics of different NO donors with regard to their promise and potential consequences in treating cerebral vasospasm. Additional novel concepts to increase NO concentrations, such as the activation of endothelial nitric oxide synthase (eNOS), are discussed.

AB Episodes of loss of control overeating (LOC) in children and adolescents - often characterized by the consumption of highly palatable dessert and snack-type foods - have been associated with a lack of awareness while eating that could lead to under- or over-estimation of how much food is consumed. However, little is known about the reporting accuracy of food intake in youth with and without LOC eating. One hundred fifty-six girls and boys were administered the Eating Disorder Examination to assess for the presence of LOC eating. Youth were queried regarding the amounts of foods consumed directly following a multi-item, laboratory buffet test meal. Children with LOC (n = 42) did not differ significantly from youth without LOC (n = 114) in reporting accuracy of total food intake (reported minus actual energy intake: 153.0 +/- 59.6 vs. 96.9 +/- 36.0 kcal; p = 0.42). However, compared to those without LOC, children with LOC were less accurate at reporting percentage of energy intake from carbohydrate (p = 0.01). Youth with LOC were also less accurate at reporting their intake of desserts (p = 0.04). Findings point to the possibility that youth with LOC may have poorer recall of sweet food consumption. Future research is required to examine whether poorer recall reflects a lack of awareness while eating palatable, sweet foods. Published by Elsevier Ltd.

DT Article
AB Background: The objective of this study was to characterize the in vitro and in vivo properties of the F(ab')(2) fragment of panitumumab and to investigate its potential for imaging and radioimmunotherapy.
Methods: The panitumumab F(ab')(2) was generated by enzymatic pepsin digestion. After the integrity and immunoreactivity of the F(ab')(2) was evaluated, the fragment was radiolabeled. In vivo studies included direct quantitation of tumor targeting and normal organ distribution of the radiolabeled panitumumab F(ab')(2) as well as planar gamma-scintigraphy and PET imaging.
Results: The panitumumab F(ab')(2) was successfully produced by peptic digest. The F(ab')(2) was modified with the CHX-A"-DTPA chelate and efficiently radiolabeled with either In-111 or Y-86. In vivo tumor targeting was achieved with acceptable uptake of radioactivity in the normal organs. The tumor targeting was validated by both imaging modalities with good visualization of the tumor at 24 h.
Conclusions: The panitumumab F(ab')(2) fragment is a promising candidate for imaging of HER1-positive cancers.

AB The forkhead box M1b (FoxM1b) transcription factor is over-expressed in human cancers, and its expression often correlates with poor prognosis. Previously, using conditional knockout strains, we showed that FoxM1b is essential for hepatocellular carcinoma (HCC) development. However, over-expression of FoxM1b had only marginal effects on HCC progression. Here we investigated the effect of FoxM1b expression in the absence of its inhibitor Arf. We show that transgenic expression of FoxM1b in an Atf-null background drives hepatic fibrosis and metastasis of HCC. We identify novel mechanisms of FoxM1b that are involved in epithelial-mesenchymal transition, cell motility, invasion and a pre-metastatic niche formation. FoxM1b activates the Akt-Snail1 pathway and stimulates expression of Stathmin, lysyl oxidase, lysyl oxidase like-2 and several other genes involved in metastasis. Furthermore, we show that an Arf-derived peptide, which inhibits FoxM1b, impedes metastasis of the FoxM1b-expressing HCC cells. The observations indicate that FoxM1b is a potent activator of tumour metastasis and that the Arf-mediated inhibition of FoxM1b is a critical mechanism for suppression of tumour metastasis.

TI Should Affective Arousal be Grounded in Perception-Action Coupling?
SO EMOTION REVIEW

DT Editorial Material
DE empathy; perception-action coupling
ID OTHERS
AB Decety (2011) considers the cognitive neuroscience of empathy and, in particular, his three-component model of empathic responding. His position is highly influential with its emotional awareness/understanding and emotional regulation components representing clear extensions of previous theorizing on empathy. In this brief commentary, I will critically consider the third of his components: affective arousal. In particular, I will consider the implications of the literature to the proposed computations, based on perception-action coupling, that underlie this component of his model. I will suggest that perception-action coupling does not underlie affective arousal but rather that this is mediated by far more simple mechanisms of emotional arousal based on conditioning.

AB Follistatin is a secreted glycoprotein required for female sex determination and early ovarian development, but the precise mechanisms regulating follistatin (Fst) gene expression are not known. Here, we investigate the roles of bone morphogenetic protein 2 (BMP2) and forkhead-domain transcription factor L2 (FOXL2) in the regulation of Fst expression in the developing mouse ovary. Bmp2 and Fst showed similar temporal profiles of mRNA expression, whereas FOXL2 protein and Fst mRNA were coexpressed in the same ovarian cells. In a cell culture model, both FOXL2 and BMP2 up-regulated Fst expression. In ex vivo mouse fetal gonad culture, exogenous BMP2 increased Fst expression, but this effect was counteracted by the BMP antagonist Noggin. Moreover, in Foxl2-null mice, Fst expression was reduced throughout fetal ovarian development, and Bmp2 expression was also reduced. Our data support a model in which FOXL2 and BMP2 cooperate to ensure correct expression of Fst in the developing ovary. Further, Wnt4-knockout mice showed reduced expression of Fst limited to early ovarian development, suggesting a role for WNT4 in the initiation, but not the maintenance, of Fst expression.

AB Three classes of DNA damage were assessed in human placentas collected (2000-2004) from 51 women living in the Teplice region of the Czech Republic, a mining area considered to have some of the worst environmental pollution in Europe in the 1980s. Polycyclic aromatic hydrocarbon (PAH)-DNA adducts were localized and semiquantified using immunohistochemistry (IHC) and the Automated Cellular Imaging System (ACIS). More generalized DNA damage was measured both by (32)P-postlabeling and by abasic (AB) site analysis. Placenta stained with antiserum elicited against DNA modified with 7 beta,8 alpha-dihydroxy-9 alpha,10 alpha-epoxy-7,8,9,10-tetrahydro-benzo[a]pyrene (BPDE) revealed PAH-DNA adduct localization in nuclei of the cytotrophoblast (CT) cells and syncytiotrophoblast (ST) knots lining the chorionic villi. The highest levels of DNA damage, 49-312 PAH-DNA adducts/10(8) nucleotides, were found by IHC/ACIS in 14 immediately fixed placenta samples. An additional 37 placenta samples were stored frozen before fixation and embedding, and because PAH-DNA adducts were largely undetectable in these samples, freezing was implicated in the loss of IHC signal. The same placentas (n = 37) contained 1.7-8.6 stable/bulky DNA adducts/10(8) nucleotides and 0.6-47.2 AB sites/10(5) nucleotides. For all methods, there was no correlation among types of DNA damage and no difference in extent of DNA damage between smokers and nonsmokers. Therefore, the data show that DNA from placentas obtained in Teplice contained multiple types of DNA damage, which likely arose from various environmental exposures. In addition, PAH-DNA adducts were present at high concentrations in the CT cells and ST knots of the chorionic villi. Environ. Mol. Mutagen. 52:58-68, 2011. (C) 2010 Wiley-Liss, Inc.

AB BACKGROUND: This commentary evolved from a workshop sponsored by the National Institute of Environmental Health Sciences titled "Superfund Contaminants: The Next Generation" held in Tucson, Arizona, in August 2009. All the authors were workshop participants.
OBJECTIVES: Our aim was to initiate a dynamic, adaptable process for identifying contaminants of emerging concern (CECs) that are likely to be found in future hazardous waste sites, and to identify the gaps in primary research that cause uncertainty in determining future hazardous waste site contaminants.
DISCUSSION: Superfund-relevant CECs can be characterized by specific attributes: They are persistent, bioaccumulative, toxic, occur in large quantities, and have localized accumulation with a likelihood of exposure. Although still under development and incompletely applied, methods to quantify these attributes can assist in winnowing down the list of candidates from the universe of potential CECs. Unfortunately, significant research gaps exist in detection and quantification, environmental fate and transport, health and risk assessment, and site exploration and remediation for CECs. Addressing these gaps is prerequisite to a preventive approach to generating and managing hazardous waste sites.
CONCLUSIONS: A need exists for a carefully considered and orchestrated expansion of programmatic and research efforts to identify, evaluate, and manage CECs of hazardous waste site relevance, including developing an evolving list of priority CECs, intensifying the identification and monitoring of likely sites of present or future accumulation of CECs, and implementing efforts that focus on a holistic approach to prevention.

AB BACKGROUND: Human exposure to inorganic arsenic (iAs), a potent oxidative stressor, causes various dermal disorders, including hyperkeratosis and skin cancer. Nuclear factor-erythroid 2-related factor 1 (NRF1, also called NFE2L1) plays a critical role in regulating the expression of many antioxidant response element (ARE)-dependent genes.
OBJECTIVES: We investigated the role of NRF1 in arsenic-induced antioxidant response and cytotoxicity in human keratinocytes.
RESULTS: In cultured human keratinocyte HaCaT cells, inorganic arsenite (iAs(3+)) enhanced the protein accumulation of long isoforms (120-140 kDa) of NRF1 in a dose-and time-dependent fashion. These isoforms accumulated mainly in the nuclei of HaCaT cells. Selective deficiency of NRF1 by lentiviral short-hairpin RNAs in HaCaT cells [NRF1-knockdown (KD)] led to decreased expression of gamma-glutamate cysteine ligase catalytic subunit (GCLC) and regulatory subunit (GCLM) and a reduced level of intra-cellular glutathione. In response to acute iAs(3+) exposure, induction of some ARE-dependent genes, including NAD(P)H:quinone oxidoreductase 1 (NQO1), GCLC, and GCLM, was significantly attenuated in NRF1-KD cells. However, the iAs(3)-induced expression of heme oxygenase 1 (HMOX-1) was unaltered by silencing NRF1, suggesting that HMOX-1 is not regulated by NRF1. In addition, the lack of NRF1 in HaCaT cells did not disturb iAs(3+)-induced NRF2 accumulation but noticeably decreased Kelch-like ECH-associated protein 1 (KEAP1) levels under basal and iAs(3+)-exposed conditions, suggesting a potential interaction between NRF1 and KEAP1. Consistent with the critical role of NRF1 in the transcriptional regulation of some ARE-bearing genes, knockdown of NRF1 significantly increased iAs(3+)-induced cytotoxicity and apoptosis.
CONCLUSIONS: Here, we demonstrate for the first time that long isoforms of NRF1 contribute to arsenic-induced antioxidant response in human keratinocytes and protect the cells from acute arsenic cytotoxicity.

AB BACKGROUND: Interest and concern regarding potentially estrogenic substances have resulted in development of model systems to evaluate mechanisms of such chemicals. Microarray studies have indicated that estradiol (E(2))-stimulated uterine responses can be divided into early and late phases. Comparison of E(2) uterine transcript profiles and those of other estrogenic chemicals of interest in vivo indicates mechanisms and activities of test compounds.
OBJECTIVES: We compared transcript responses and mechanisms of response using mouse reproductive tracts after treatment with E(2), estriol (E(3)), bisphenol A (BPA), and 2,2-bis(p-hydroxyphenyl)-1,1,1-trichloroethane (HPTE).
METHODS: Uterine RNA from ovariectomized wild-type mice, estrogen receptor alpha (ER alpha) knockout (alpha ERKO) mice, and mice expressing a DNA-binding-deficient ER alpha (KIKO) treated with E(2), E(3), BPA, or HPTE for 2 or 24 hr was analyzed by microarray. Resulting regulated transcripts were compared by hierarchical clustering and correlation analysis, and response patterns were verified by reverse-transcription real-time polymerase chain reaction (RT-PCR).
RESULTS: Both xenoestrogens, BPA and HPTE, showed profiles highly correlated to that of E(2) in the early response phase (2 hr), but the correlation diminished in the later response phase (24 hr), similar to the known weak estrogen E(3). Both xenoestrogens also mimicked E(2) in samples from KIKO mice, indicating that they are able to utilize the indirect tethering mode of ER alpha signaling. No response was detected in ER alpha-null uteri, indicating that ER alpha mediates the responses.
CONCLUSION: Our study forms a basis on which patterns of response and molecular mechanisms of potentially estrogenic chemicals can be assessed.

EXPOSURE; MORTALITY; WORKERS; COHORT; SKIN; DERMATITIS
AB Background: Occupational exposure to mineral oil-based metalworking fluids has been consistently linked with skin conditions such as contact dermatitis and squamous cell skin cancer, especially of the scrotum. We examined the incidence of malignant melanoma in a study of autoworkers.
Methods: We followed a cohort of autoworkers from 1985 through 2004 for cancer incidence. Hazard ratios (HRs) were estimated in Cox models for cumulative exposure to total particulate of straight fluid (neat oil), soluble fluid (oil emulsified in water), and synthetic fluid (no oil). Exposure was partitioned into time windows by latency and by calendar periods defined by changes in the content of polycyclic aromatic hydrocarbon in the refined oils. The population was restricted to workers born after 1935. We examined the date-of-birth restriction in a sensitivity analysis.
Results: On the basis of 76 incident cases of malignant melanoma in the cohort of 14,139 white males, the HR was 1.99 (95% confidence interval = 1.00-3.96) for the highest category of straight fluid. Risk was greatest in the most recent time window. Penalized splines suggested a linear exposure-response over the full range of exposure. The change in HR for malignant melanoma per mg/m(3)-year of straight fluid increased monotonically from 1.01 to 1.04, when the date-of-birth restriction increased from 1925 to 1945 in 5-year intervals. Results for soluble fluid were more modest. There was no association with synthetic fluid.
Conclusions: Results provide evidence, based on quantitative measures of metalworking fluid, that oil-based fluid, particularly straight mineral oils, are associated with the incidence of malignant melanoma.

AB Autoimmune diseases, which comprise over 80 clinically distinct conditions, are characterized by the presence of autoantibodies or autoreactive T cells directed against self structures (autoantigens). While these often incurable disorders appear to be rapidly increasing in recognition throughout the world, their rarity, heterogeneity and complex etiologies have limited our understanding of their pathogeneses. The precise mechanisms for the development of autoimmune diseases are not known, however, evidence from many complementary lines of investigation suggests that autoimmune diseases result from the interactions of both environmental and genetic risk factors. While considerable progress has been made in understanding multiple genetic risk factors for many autoimmune diseases, relatively little information is now available regarding the role of the environment in the development of these illnesses. This chapter examines the limited but growing evidence for the role of the environment in the development and progression of autoimmune diseases, the specific exposures that have been suspected of being involved, the possible mechanisms by which these agents may induce and sustain autoimmune processes and the approaches needed to better understand these issues in the future. Identifying the necessary and sufficient genetic and environmental risk factors for disease holds the promise of allowing for the prevention of some illnesses through avoidance of environmental risk factors by genetically susceptible individuals or via gene or other therapies to correct the effects of deleterious genetic risk factors in the case of unavoidable environmental agents.

ID DRIVING SIMULATION; PERCEPTION; EXPERIENCE; TASKS
AB Several studies have documented that the failure of drivers to attend to the forward roadway for a period lasting longer than 2-3 s is a major cause of highway crashes. Moreover, several studies have demonstrated that novice drivers are more likely to glance away from the roadway than the experienced drivers for extended periods when attempting to do a task inside the vehicle. The present study examines the efficacy of a PC-based training programme (FOrward Concentration and Attention Learning, FOCAL) designed to teach novice drivers not to glance away for these extended periods of time. A FOCAL-trained group was compared with a placebo-trained group in an on-road test, and the FOCAL-trained group made significantly fewer glances away from the roadway that were more than 2 s than the placebo-trained group. Other measures indicated an advantage for the FOCAL-trained group as well.
Statement of relevance: Distracted driving is increasingly a problem, as cell phones, navigation systems, and other in-vehicle devices are introduced into the cabin of the automobile. A training programme is described that has been tested on the open road and can reduce the behaviours that lead to crashes caused by the distracted driving.

AB The phenomenon of multidrug resistance in cancer is often associated with the overexpression of the ABC (ATP-binding cassette) transporters Pgp (P-glycoprotein) (ABCB1), MRP1 (multidrug resistance-associated protein 1) (ABCC1) and ABCG2 [BCRP (breast cancer resistance protein)]. Since the discovery of Pgp over 35 years ago, studies have convincingly linked ABC transporter expression to poor outcome in several cancer types, leading to the development of transporter inhibitors. Three generations of inhibitors later, we are still no closer to validating the 'Pgp hypothesis', the idea that increased chemotherapy efficacy can be achieved by inhibition of transporter-mediated efflux. In this chapter, we highlight the difficulties and past failures encountered in the development of clinical inhibitors of ABC transporters. We discuss the challenges that remain in our effort to exploit decades of work on ABC transporters in oncology. In learning from past mistakes, it is hoped that ABC transporters can be developed as targets for clinical intervention.

AB Over recent years, genome-wide association studies have contributed to our understanding of genetic susceptibility to sporadic cancer. In this study, we assessed the association between upper gastrointestinal cancer risk and four genome-wide association studies-identified single nucleotide polymorphisms (SNPs), implicated earlier in prostate and colorectal cancer susceptibility. Genotyping for each SNP was performed in two independent Caucasian population-based case-control studies. The first study comprised 290 gastric cancer cases and 374 controls. The second study included 185 noncardia gastric cancers, 123 cardia cancers, 158 oesophageal cancers and 209 controls. Odds ratios (ORs) were computed from logistic models and adjusted for potential confounding variables. An inverse association was observed between the SNP rs1447295, located at 8q24, and gastric cancer risk in the first study population (OR = 0.63; 95% confidence interval: 0.41-0.97). A positive association was observed for the same SNP and oesophageal squamous cell carcinoma in the second study population (OR = 7.43; 95% confidence interval: 1.37-49.98). No significant associations were detected in either study for the three remaining SNPs (rs6983297, rs10505477 and rs719725). Our data represent novel findings on heritable susceptibility to gastric and oesophageal cancer and warrant validation in additional populations.

AB Heart failure with preserved ejection fraction (HFPEF) is increasingly recognized as a major public health problem worldwide. Significant advances have been made in our understanding of the epidemiology of HFPEF over the past two decades, with the publication of numerous population-based epidemiological studies, large heart failure registries, and randomized clinical trials. These recent studies have provided detailed characterization of larger numbers of patients with HFPEF than ever before. This review summarizes the state of current knowledge with regards to the disease burden, patient characteristics, clinical course, and outcomes of HFPEF. Despite the wealth of available data, substantive gaps in knowledge were identified. These gaps represent opportunities for further research in HFPEF, a syndrome that is clearly a rising societal burden and that is associated with substantial morbidity and mortality.

AB VACTERL association involves the presence of specific congenital, multi-organ malformations that tend to co-occur. Clinical and research efforts typically center on pediatric patients, and there is a scarcity of information in the literature regarding VACTERL-related issues and outcomes in adulthood. We describe here 11 adults with features of VACTERL association ascertained through our research study on the condition. In our cohort of adult patients, approximately 25% of medically significant malformations that are component features of VACTERL association, including 40% of vertebral, 50% of cardiac, and 50% of renal anomalies, were not identified during childhood. Additionally, medical sequelae of many of the primary malformations identified in infancy or early childhood persist or are first reported in adulthood. These sequelae can involve challenging medical and surgical management in adulthood. As most adults with VACTERL association are not specifically followed for VACTERL-related issues, a more uniform diagnostic work-up and a low threshold for investigation of medical sequelae of the primary disorder may enhance the quality of clinical management in these patients.

AB Reliable identification of the subthalamic nucleus (STN) and globus pallidus interna (GPi) is critical for deep brain stimulation (DBS) of these structures. The purpose of this study was to compare the visibility of the STN and GPi with various MRI techniques and to assess the suitability of each technique for direct stereotactic targeting.
MR images were acquired from nine volunteers with T2- and proton density-weighted (PD-W) fast spin echo, susceptibility-weighted imaging (SWI), phase-sensitive inversion recovery and quantitative T1, T2 and T2* mapping sequences. Contrast-to-noise ratios (CNR) for the STN and GPi were calculated for all sequences. Targeting errors on SWI were evaluated on magnetic susceptibility maps. The sequences demonstrating the best conspicuity of DBS target structures (SWI and T2*) were then applied to ten patients with movement disorders, and the CNRs for these techniques were assessed.
SWI offers the highest CNR for the STN, but standard PD-W images provide the best CNR for the pallidum. Susceptibility maps indicated that the GPi margins may be shifted slightly on SWI, although no shifts were seen for the STN.
SWI may improve the visibility of the STN on pre-operative MRI, potentially improving the accuracy of direct stereotactic targeting.

AB X-ray imaging techniques based on grating interferometers rely on transmission gratings to detect x-ray refraction and scattering in a sample. Gratings periods below 2 microns are challenging to realize due to the high aspect ratio of the structures. We propose a method to fabricate transmission gratings with sub-micron periods over centimeter areas by multilayer coating of a staircase (echelle) substrate. The advantage of this approach is the high aspect ratio of multilayer coating and the large area of the echelle substrate. The staircase pattern is etched on the surface of a silicon wafer through anisotropic etching. Multiple layers are deposited on the horizontal surfaces of the stairs by magnetron sputtering in a single run. The layers alternate between two materials of different absorption coefficients or refractive indices. The layer thickness d is designed to be (stair height)/2N, where 2N is the total number of layers. The incident x-ray beam is parallel to the layers and oblique to the wafer surface. Each stair of the echelle substrate forms a micro grating of period 2d, and the array of micro gratings together act as a single grating over a large area given the right continuity conditions. The grating period potentially can be below 100 nm. We present theoretical description of wave diffraction by the grating array, and results of the first fabrication test with magnetron sputtering deposition.

AB Effective adoptive T-cell therapy of cancer occurs after allogeneic bone marrow transplantation, and is now increasingly observed after autologous transplantation. As the clinical practice of each field evolves and the biologic underpinnings of these two seemingly disparate approaches are elucidated, four converging themes have emerged. (1) T-cell antigen specificity. The alloreactive T-cell graft-versus-tumor response is difficult to dissociate from potentially lethal graft-versus-host disease (GVHD); as such, efforts are underway to enhance antigen-specificity after allogeneic transplantation. By comparison, the field of autologous T-cell therapy has now largely redefined itself by use of highly specific T-cell receptor reactivities, which may ultimately prove limiting in terms of tumor escape mechanisms; efforts are therefore underway to broaden antigenic reactivities after autologous transplantation. (2) Host conditioning. Myeloablative conditioning used in allogeneic transplantation causes significant morbidity and mortality even in young and healthy patients, thereby limiting broader application to the majority of cancer patients; in response, less intensive and better tolerated nonmyeloablative regimens are being developed. By comparison, autologous T-cell therapy has been primarily limited by lack of efficacy, and in response, investigators have increased host conditioning to myeloablative levels to create immune space that facilitates T-cell expansion and effectiveness in vivo. (3) T-cell function. The evolving discipline of T-cell biology will continue to enhance the efficacy of both autologous and allogeneic transplantation therapy. The quality of the T-cell response is of paramount importance, and is determined by T-cell differentiation status, apoptotic tendency, and cytokine phenotype vis-a-vis Th1, Th2, Treg, and Th17 balance; modulation of this balance for therapeutic gain will depend upon an ability to understand and control an emerging phenomenon termed T-cell plasticity. (4) T-cell-mediated immune pathology. GVHD after allogeneic transplantation has been an instrumental model system for understanding T-cell pathology; importantly, cellular and molecular mechanisms underlying GVHD may also contribute to toxicities observed after effective autologous T-cell therapy. As such, both allogeneic and autologous immunotherapies are now confronted with an overall goal of maximizing T-cell efficacy while limiting T-cell toxicity. Attainment of such enhanced therapeutic windows may be facilitated by recent developments in immune cell modulation, including use of cell fate control genes and use of inhibitors of the mammalian target of rapamycin (mTOR) and JAK/STAT pathways. In conclusion, converging themes in autologous and allogeneic transplantation therapy indicate that a bright future will emerge for T-cell therapies, the success of which will be realized through advances in T-cell biology and T-cell engineering.

AB Leishmaniasis is a parasitic disease affecting similar to 12 million people. Control of infection (e.g. in C57BL/6 mice) results from IL-12-dependent production of IFN gamma by Th1/Tc1 cells. In contrast, BALB/c mice succumb to infection because of preferential Th2-type cytokine induction. Infected dendritic cells (DC) represent important sources of IL-12. Genetically determined differences in DC IL-1 alpha/beta production contribute to disease outcome. Whereas the course of disease was not dramatically altered in IL-1RI-/- mice, local administration of IL-1 alpha to infected C57BL/6 mice improved disease outcome. To definitively elucidate the involvement of IL-1 in immunity against leishmaniasis, we now utilized IL-1 alpha/beta-double-deficient C57BL/6 mice. C57BL/6 mice are believed to be a good surrogate model for human, self limited cutaneous leishmaniasis (CL). Leishmania major-infected IL-1 alpha/beta-/- mice were resistant to experimental CL comparable to controls. In addition, DC-based vaccination against leishmaniasis in C57BL/6 mice was independent of IL-1. Thus, in Leishmania-resistant C57BL/6 mice, IL-1 signalling is dispensable for protection.

AB Nitric oxide (NO) and NO-derived reactive nitrogen species (RNS) are present in the food vacuole (FV) of Plasmodium falciparum trophozoites. The product of PFL1555w, a putative cytochrome 65, localizes in the FV membrane, similar to what was previously observed for the product of PF13_0353, a putative cytochrome 65 reductase. These two gene products may contribute to NO generation by denitrification chemistry from nitrate and/or nitrite present in the erythrocyte cytosol. The possible coordination of NO to heme species present in the food vacuole was probed by resonance Raman spectroscopy. The spectroscopic data revealed that in situ generated NO interacts with heme inside the intact FVs to form ferrous heme nitrosyl complexes that influence intra-vacuolar heme solubility. The formation of heme nitrosyl complexes within the FV is a previously unrecognized factor that could affect the equilibrium between soluble and crystallized heme within the FV in vivo.

AB Importance of the field: Recent advances in the understanding of the oncogenesis of head and neck squamous cell carcinomas (HNSCC) have revealed multiple dysregulated signaling pathways. One frequently altered axis is the EGFR-PI3K-Akt-mTOR pathway. This pathway plays a central role in numerous cellular processes including metabolism, cell growth, apoptosis, survival and differentiation, which ultimately contributes to HNSCC progression.
Areas covered in this review: Books, journals, databases and websites have been searched to provide a current review on the subject.
What the reader will gain: This article reviews the current understanding of EGFR-PI3K-Akt-mTOR signaling in HNSCC, including the impact of both genetic and epigenetic alterations. This review further highlights the potential of targeting this signaling cascade as a promising therapeutic approach in the treatment of HNSCC.
Take home message: Genetic alterations of several nodes within this pathway, including both genetic and epigenetic changes, leading to either oncogene activation or inactivation of tumor suppressors have frequently been implicated in HNSCC. Consequently, drugs that target the central nodes of this pathway have become attractive for molecular oriented cancer therapies. Numerous preclinical and clinical studies are being performed in HNSCC; however, more studies are still needed to better understand the biology of this pathway.

AB In this article, we report that primary leukemic B-cell precursors from B-lineage acute lymphoblastic leukemia (ALL) patients overexpress multiple JAK3-activating cytokines as well as their receptors. We also show that amplified expression of JAK3 pathway genes in B-lineage ALL is associated with steroid resistance and relapse. Our findings further demonstrate that several different diagnostic classes of B-lineage lymphoid malignancies exhibit upregulated expression of JAK3 pathway genes, which are associated with an overexpression of genes for JAK3-stimulatory cytokines with concomitant deficiency of JAK3-inhibitory signaling molecules. Thus, despite the rare occurrence of activating JAK3 mutations, JAK3 appears to be constitutively active and represents a viable molecular target in the treatment of a broad range of B-lineage lymphoid malignancies, including B-lineage ALL.

AB Immune-sensitive urologic malignancies include prostate, kidney and bladder cancers. To date, most immunotherapeutic treatments have been applied to advanced metastatic disease. Limited efficacy in this setting is likely due to an excessive disease burden, which overwhelms the capacity of the immune system. Immunotherapy has not been widely utilized in a low-disease-burden state - a setting in which the immune system may be best suited to effectively mount a clinically meaningful response. The emergence of high-intensity focused ultrasound, and more recently, low-intensity focused ultrasound technologies, have demonstrated not only immune-stimulatory effects but also an interesting capacity to alter tissue architecture and cell membrane properties, which may be exploited to increase tumoral uptake of drugs and vaccines. In this article, we review the literature supporting the novel use of ultrasound combination therapy with adjunctive agents in the treatment of urologic malignancy.

AB Positron emission tomography (PET) offers a strategic imaging platform to provide a map of functional neural correlates associated with the underlying cognitive deficits in schizophrenia. It enables regional cerebral glucose metabolism and dopaminergic and serotonergic receptor function to be studied. PET neuroimaging can therefore be used in drug development and to study putative treatments. Recent PET studies of the first-generation antipsychotics flupentixol and haloperidol, and of the second-generation antipsychotics risperidone, aripiprazole, quetiapine, sertindole, ziprasidone, paliperidone and olanzapine, have been carried out; modulation of limbic circuitry has been found to be a predictor of treatment response. PET can also be used to predict and monitor likely extrapyramidal side effects from antipsychotic treatment. PET and neuropsychological testing can together also allow the study of putative molecular genetic changes associated with schizophrenia. Advances in the imaging, cognition and molecular genetics are likely to lead to the development of future diagnostics, treatments and novel pharmacological agents.

AB Marburg and Ebola viruses cause severe hemorrhagic fever in humans and nonhuman primates. Currently, there are no effective treatments and no licensed vaccines; although a number of vaccine platforms have proven successful in animal models. The ideal filovirus vaccine candidate should be able to provide rapid protection following a single immunization, have the potential to work postexposure and be cross-reactive or multivalent against all Marburg virus strains and all relevant Ebola virus species and strains. Currently, there are multiple platforms that have provided prophylactic protection in nonhuman primates, including DNA, recombinant adenovirus serotype 5, recombinant human parainfluenza virus 3 and virus-like particles. In addition, a single platform, recombinant vesicular stomatitis virus, has demonstrated both prophylactic and postexposure protection in nonhuman primates. These results demonstrate that achieving a vaccine that is protective against filoviruses is possible; the challenge now is to prove its safety and efficacy in order to obtain a vaccine that is ready for human use.

AB Studies conducted as of today collectively suggest that the degradation of collagen in mammals is carried out in equal parts within the extracellular environment, via the action of a limited number of secreted or plasma membrane proteases with the unique ability to cleave native collagen, and intracellularly, via an assortment of lysosomal cathepsins that degrade collagen made available through its uptake by specific collagen endocytic receptors. Emerging evidence indicates that these two principal mechanisms for collagen degradation cooperate to form a single pathway that executes the sequential and complete degradation of collagen during both physiological tissue remodeling and pathological remodeling, including tumor progression. The chapter summarizes the prevailing paradigms regarding the turnover of this abundant extracellular matrix molecule.

AB Objective: To determine whether frozen-thawed blastocyst transfer pregnancy rates (PR) are lower in African-American compared with white women.
Design: Retrospective review of frozen blastocyst cycles.
Setting: University-based assisted reproductive technology (ART) program.
Patient(s): All patients who underwent a frozen blastocyst transfer between 2003 and 2008.
Intervention: None.
Main Outcome Measure(s): Live birth rate.
Result(s): One hundred sixty-nine patients underwent transfer of a frozen-thawed blastocyst. African-American women had a higher incidence of leiomyoma (40% vs. 10%) and tubal and uterine factor infertility. There was no difference in the live birth rate for African-American patients (28.0%) compared with white patients (30.2%). Of the patients who underwent a frozen-thawed blastocyst transfer, 58% (n = 98) had their fresh, autologous IVF cycle, which produced the cryopreserved blastocyst, at Walter Reed Medical Center. A higher peak serum E(2) level was noted in African-American patients (5,355 pg/mL) compared with white patients (4,541 pg/mL). During the fresh cycle, the live birth rates between African-American and white patients were significantly different at 16.7% versus 39.7%, respectively.
Conclusion(s): Live birth rates after frozen blastocyst transfer are not different between African-American and white women despite a fourfold higher incidence of leiomyomas in African-American women. (Fertil Steril (R) 2011; 95: 89-93. (C)2011 by American Society for Reproductive Medicine.)

TI Effect of the insulin sensitizers metformin and pioglitazone on

AB Objective: To compare the effect of two different insulin sensitizers, metformin and pioglitazone, on endothelial function in women with polycystic ovary syndrome (PCOS).
Design: Prospective randomized study.
Setting: University Hospital endocrinology outpatient clinic.
Patient(s): Young women with PCOS (aged 23.3 +/- 4.9 years).
Intervention(s): Patients were assigned randomly to no treatment (n = 14), metformin 850 mg two times per day (n = 15), and pioglitazone 30 mg daily (n = 14) for 6 months. Healthy age-and body mass index-matched women served as controls (n = 14).
Main Outcome Measure(s): Brachial artery flow-mediated dilation was studied at baseline and 6 months.
Result(s): Women with PCOS had higher insulin resistance and hyperandrogenism indices and lower flow-mediated dilation compared with controls. The three groups of women with PCOS did not differ at baseline. No differences were observed at follow-up in women who received no treatment. Metformin and pioglitazone improved flow-mediated dilation to a similar extent, restoring it to normal values at 6 months. Both insulin sensitizers induced favorable changes in insulin resistance and hyperandrogenism indices in women with PCOS. Independent predictors of flow-mediated dilation improvement at 6 months were treatment with insulin sensitizers and reduction in insulin resistance.
Conclusion(s): In young women with PCOS, treatment with metformin or pioglitazone for 6 months induces a similar beneficial effect on endothelial function; this may be partially attributed to an improvement in insulin resistance. Further research is needed to investigate whether treatment with insulin sensitizers in women with PCOS also reduces cardiovascular risk. (Fertil Steril(R) 2011;95:203-9.

ID NATURAL-HISTORY; UNITED-STATES; RENAL MASSES; HYSTERECTOMY
AB Objective: To describe the short-term changes in growth of uterine leiomyomas (fibroids).
Design: Prospective observational study.
Setting: University research center.
Patient(s): Premenopausal women with fibroids (18 blacks and 18 whites) recruited through a physician network and community outreach.
Intervention(s): Not applicable.
Main Outcome Measure(s): The volumes of 101 fibroids were measured at enrollment, 3, 6, and 12 months with magnetic resonance imaging, resulting in three interval-specific growth rates. Growth spurts were defined by interval growth rates >= 30% per 3 months and substantially greater than during other intervals of observation. An overall measure of short-term change in fibroid growth was calculated as the variance of the three interval-specific growth rates.
Result(s): Growth spurts were observed in 37 of the 101 fibroids, a prevalence nearly tenfold higher than that attributable to potential measurement error. Fibroids from the same woman did not have similar short-term growth, nor were woman-specific factors (age, race/ethnicity, parity, body mass) or the fibroid position in the uterus important. However, large fibroids (>5 cm diameter) had less short-term change than smaller fibroids.
Conclusion(s): Short spurts of growth are common for fibroids, suggesting that tumor biology may change rapidly. (Fertil Steril(R) 2011;95:242-6. (C) 2011 by American Society for Reproductive Medicine.)

AB To compare methylation profiles and expression levels of Brahma at different stages of spermatogenesis, and to identify the methylation pattern during oogenesis, we analyzed gene expression and methylation patterns in murine germ cells at various developmental stages. The methylation levels of CpG islands within Brahma increased during spermatogenesis and decreased during oogenesis. This change in methylation pattern correlates with the change in expression of Brahma during spermatogenesis. As the degree of methylation increases, the expression decreases. The change in methylation is opposite during oogenesis, which suggests opposite expression levels. (Fertil Steril (R) 2011;95:382-4. (C) 2011 by American Society for Reproductive Medicine.)

AB Natural products chemistry is the discipline that lies at the heart of modern pharmacognosy. The field encompasses qualitative and quantitative analytical tools that range from spectroscopy and spectrometry to chromatography. Among other things, modern research on crude botanicals is engaged in the discovery of the phytochemical constituents necessary for therapeutic efficacy, including the synergistic effects of components of complex mixtures in the botanical matrix. In the phytomedicine field, these botanicals and their contained mixtures are considered the active pharmaceutical ingredient (API), and pharmacognosists are increasingly called upon to supplement their molecular discovery work by assisting in the development and utilization of analytical tools for assessing the quality and safety of these products. Unlike single-chemical entity APIs, botanical raw materials and their derived products are highly variable because their chemistry and morphology depend on the genotypic and phenotypic variation, geographical origin and weather exposure, harvesting practices, and processing conditions of the source material. Unless controlled, this inherent variability in the raw material stream can result in inconsistent finished products that are under-potent, over-potent, and/or contaminated. Over the decades, natural product chemists have routinely developed quantitative analytical methods for phytochemicals of interest. Quantitative methods for the determination of product quality bear the weight of regulatory scrutiny. These methods must be accurate, precise, and reproducible. Accordingly, this review discusses the principles of accuracy (relationship between experimental and true value), precision (distribution of data values), and reliability in the quantitation of phytochemicals in natural products.

AB Flow cytometry is the most widely used technology for analyzing apoptosis. The multiparametric nature of flow cytometry allows several apoptotic characteristics to be combined in a single sample, making it a powerful tool for analyzing the complex progression of apoptotic death. This chapter provides guidelines for combining caspase detection, annexin V binding, DNA dye exclusion, and other single apoptotic assays into multiparametric assays.
This approach to analyzing apoptosis provides far more information than single parameter assays that provide only an ambiguous "percent apoptotic" result, given that multiple early, intermediate and late apoptotic stages can be visualized simultaneously. This multiparametric approach is also amenable to a variety of flow cytometric instrumentation, both old and new.

AB Flow cytometry immunophenotyping (FCI) of hematolymphoid specimens is a powerful tool in clinical medicine aiding in the accurate diagnosis and subclassification of acute and chronic leukemias, non-Hodgkin lymphomas, myelodysplasia, and other hematolymphoid neoplastic processes. Multiple flow cytometric strategies arc used to evaluate hematolymphoid populations, including identification of neoplastic populations with aberrant immunophenotypes, abnormal maturation patterns, monotypic kappa/lambda light chain expression, restricted V-beta expression, and abnormal light scatter properties. In this chapter, we present a general approach to analyze hematolymphoid populations. Specimen handling, gating strategies, and appropriate antibody panels for flow cytometric detection of abnormal hematologic populations are presented.

AB Cell type-specific expression of fluorescent proteins allows the purification of rare cells from complex tissues by flow cytometry. This strategy is especially useful for molecular analysis of cancer cells because these cells can be effectively purified away from the noncancerous tumor stroma. Coexpression of bioluminescence with fluorescence makes further allows in vivo tracking of cancer cells, which can then be purified at specific tumorigenic stages. Here, we describe protocols for purifying rare skin stem cells, and for in vivo monitoring and purification of cancer cells from lung metastases. Also described is a protocol for the isolation of total RNA from the purified cells for the purpose of performing gene expression profiling.

ID UNFIXED CELLS; BIOSAFETY GUIDELINES
AB Over the past decade, there has been a rapid growth in the number of BSL-3 and BSL-4 laboratories in the USA and an increase in demand for infectious cell sorting in BSL-3 laboratories. In 2007, the International Society for Advancement of Cytometry (ISAC) Biosafety Committee published standards for the sorting of unfixed cells and is an important resource for biosafety procedures when performing infectious cell sorting. Following a careful risk assessment, if it is determined that a cell sorter must be located within a BSL-3 laboratory, there are a variety of factors to be considered prior to the establishment of the laboratory. This chapter outlines procedures for infectious cell sorting in a BSL-3 environment to facilitate the establishment and safe operation of a BSL-3 cell sorting laboratory. Subjects covered include containment verification, remote operation, disinfection, personal protective equipment (PPE), and instrument-specific modifications for enhanced aerosol evacuation.

AB Deoxynivalenol (DON) is a trichothecene mycotoxin found on wheat, maize and barley. In ecological surveys in China, DON and other trichothecenes have been implicated in acute poisoning episodes and linked with the incidence of esophageal cancer. In order to better understand exposure patterns, this pilot survey provided a combined measure of urinary un-metabolised or free DON (fD) and its glucuronide metabolite (DG) in a subset of 60 samples taken from the Shanghai Women's Health Study cohort, China. Samples were collected in 1997/1998 from women age 40-70 years. Urinary fD+DG combined was detected in 58/60 (96.7%) samples (mean 5.9 ng DON/mg creatinine; range nd - 30.5); a similar frequency, and a mean level approximately half, of that previously observed for women in the UK. Wheat consumption was approximately 25% of that consumed by western diets; thus DON contamination of wheat may be higher in Shanghai than the UK. The de-epoxy metabolite of DON, a detoxification product observed in animals, was not detected, suggesting that humans may be particularly sensitive to DON due to a more restricted detoxification capacity.

AB It has been well recognized that dietary proteins provide a rich source of biologically active peptides. Today, milk proteins are considered the most important source of bioactive peptides and an increasing number of bioactive peptides have been identified in milk protein hydrolysates and fermented dairy products. Bioactive peptides derived from milk proteins offer a promising approach for the promotion of health by means of a tailored diet and provide interesting opportunities to the dairy industry for expansion of its field of operation. The potential health benefits of milk protein-derived peptides have been a subject of growing commercial interest in the context of health-promoting functional foods. Hence, these peptides are being incorporated in the form of ingredients in functional and novel foods, dietary supplements and even pharmaceuticals with the purpose of delivering specific health benefits.

AB In this study, a Cu2+ chelate of the novel thiosemicarbazone NSC 689534 was evaluated for in vitro and in vivo anti-cancer activity. Results demonstrated that NSC 689534 activity (low micromolar range) was enhanced four- to fivefold by copper chelation and completely attenuated by iron. Importantly, once formed, the NSC 689534/Cu2+ complex retained activity in the presence of additional iron or iron-containing biomolecules. NSC 689534/Cu2+ mediated its effects primarily through the induction of ROS, with depletion of cellular glutathione and protein thiols. Pretreatment of cells with the antioxidant N-acetyl-l-cysteine impaired activity, whereas NSC 689534/Cu2+ effectively synergized with the glutathione biosynthesis inhibitor buthionine sulfoximine. Microarray analysis of NSC 689534/Cu2+-treated cells highlighted activation of pathways involved in oxidative and ER stress/UPR, autophagy, and metal metabolism. Further scrutiny of the role of ER stress and autophagy indicated that NSC 689534/Cu2+-induced cell death was ER-stress dependent and autophagy independent. Last, NSC 689534/Cu2+ was shown to have activity in an HL60 xenograft model. These data suggest that NSC 689534/Cu2+ is a potent oxidative stress inducer worthy of further preclinical investigation.

AB Previous studies have suggested that increased levels of endocannabinoids in various cardiovascular disorders (e.g., various forms of shock, cardiomyopathies, atherosclerosis) through the activation of CB(1) cannabinoid receptors may promote cardiovascular dysfunction and tissue injury. We have investigated the role of the main endocannabinoid anandamide-metabolizing enzyme (fatty acid amide hydrolase; FAAH) in myocardial injury induced by an important chemotherapeutic drug, doxorubicin (DOX; known for it cardiotoxicity mediated by increased reactive oxygen and nitrogen species generation), using well-established acute and chronic cardiomyopathy models in mice. The DOX-induced myocardial oxidative/nitrative stress (increased 4-hydroxynonenal, protein carbonyl, and nitrotyrosine levels and decreased glutathione content) correlated with multiple cell death markers, which were enhanced in FAAH knockout mice exhibiting significantly increased DOX-induced mortality and cardiac dysfunction compared to their wild type. The effects of DOX in FAAH knockouts were attenuated by CB(1) receptor antagonists. Furthermore, anandamide induced enhanced cell death in human cardiomyocytes pretreated with FAAH inhibitor and enhanced sensitivity to ROS generation in inflammatory cells of FAAH knockouts. These results suggest that in pathological conditions associated with acute oxidative/nitrative stress FAAH plays a key role in controlling the tissue injury that is, at least in part, mediated by the activation of CB(1) receptors by endocannabinoids.

DYSFUNCTION
AB RAGE is pattern recognizing receptors for diverse endogenous ligands. RAGE activation by RAGE ligands is known to be associated with reactive oxygen species generation, activation of NF kappa B, as well as recruitment of proinflammatory cells. Activated endothelial cells, vascular smooth muscle cells in atherosclerotic plaques and activated inflammatory cells all have increased expression of RAGE, which with its interaction with RAGE ligands increases the secretion of proinflammatory cytokines and cell adhesion molecules. Furthermore, RAGE may have a significant role in leukocyte recruitment into the intima of the atherosclerosis. Initial insults resulting in endothelial dysfunction will result in leukocyte infiltration, oxidative stress and vascular inflammation that is amplified by RAGE activation. RAGE and its interaction with RAGE ligands may be important for initializing and maintaining the pathological processes that result in various entities of cardiovascular disease. Soluble RAGE competitively inhibits the binding of RAGE ligands to RAGE and attenuates the development of atherosclerosis in vivo. Thus RAGE may be a promising target for treatment of cardiovascular disease in the future.

AB Breast cancer remains a major cause of death in the United States as well as the rest of the world. In view of the limited treatment options for patients with advanced breast cancer, preventive and novel therapeutic approaches play an important role in combating this disease. The plant-derived triterpenoids, commonly used for medicinal purposes in many Asian countries, posses various pharmacological properties. A large number of triterpenoids are known to exhibit cytotoxicity against a variety of tumor cells as well as anticancer efficacy in preclinical animal models. Numerous triterpenoids have been synthesized by structural modification of natural compounds. Some of these analogs are considered to be the most potent antiinflammatory and anticarcinogenic triterpenoids known. This review examines the potential role of natural triterpenoids and their derivatives in the chemoprevention and treatment of mammary tumors. Both in vitro and in vivo effects of these agents and related molecular mechanisms are presented. Potential challenges and future directions involved in the advancement of these promising compounds in the prevention and therapy of human breast cancer are also identified.

TI Hypohidrotic ectodermal dysplasia and immunodeficiency with coincident
NEMO and EDA mutations
SO FRONTIERS IN IMMUNOLOGY

DT Article
DE NEMO; EDA; ectodermal dysplasia; immunodeficiency
AB Ectodermal dysplasias (ED) are uncommon genetic disorders resulting in abnormalities in ectodermally derived structures. Many ED-associated genes have been described, of which ectodysplasin-A (FDA) is one of the more common. The NE-03 essential modulator (NEMO encoded by the IKBKG gene) is unique in that mutations result in severe humoral and cellular immunologic defects in addition to ED. We describe three unrelated kindreds with defects in both FDA and IKBKG resulting from X-chromosome crossover. This demonstrates the importance of thorough immunologic consideration of patients with ED even when an FDA etiology is confirmed, and raises the possibility of a specific phenotype arising from coincident mutations in FDA and IKBKG.

DE tregs; Th17; immune suppression mechanism; BIM cytokine deprivation
death; apoptosis; regulatory T cells; Foxp3; cytokine consumption
AB CD4(+)CD25(+)Foxp3(+) T lymphocytes, known as regulatory T cells or T-regs, have been proposed to be a lineage of professional immune suppressive cells that exclusively counteract the effects of the immunoprotective "helper" and "cytotoxic" lineages of T lymphocytes. Here we discuss new concepts on the mechanisms and functions of Tregs. There are several key points we emphasize: 1. Tregs exert suppressive effects both directly on effector T cells and indirectly through antigen-presenting cells; 2. Regulation can occur through a novel mechanism of cytokine consumption to regulate as opposed to the usual mechanism of cytokine/chemokine production; 3. In cases where CD4(+) effectorT cells are directly inhibited by T-regs, it is chiefly through a mechanism of lymphokine withdrawal apoptosis leading to polyclonal deletion; and 4. Contrary to the current view, we discuss new evidence that T-regs, similar to otherT-cells lineages, can promote protective immune responses in certain infectious contexts (Chen et al., 2011; Pandiyan et al., 2011). Although these points are at variance to varying degrees with the standard model of Treg behavior, we will recount developing findings that support these new concepts.

AB Infections by obligate intracellular bacterial pathogens result in significant morbidity and mortality worldwide. These bacteria include Chlamydia spp., which causes millions of cases of sexually transmitted disease and blinding trachoma annually, and members of the alpha-proteobacterial genera Anaplasma, Ehrlichia, Orientia, and Rickettsia, agents of serious human illnesses including epidemic typhus. Coxiella burnetii, the agent of human Q fever, has also been considered a prototypical obligate intracellular bacterium, but recent host cell-free (axenic) growth has rescued it from obligatism. The historic genetic intractability of obligate intracellular bacteria has severely limited molecular dissection of their unique lifestyles and virulence factors involved in pathogenesis. Host cell restricted growth is a significant barrier to genetic transformation that can make simple procedures for free-living bacteria, such as cloning, exceedingly difficult. Low transformation efficiency requiring long-term culture in host cells to expand small transformant populations is another obstacle. Despite numerous technical limitations, the last decade has witnessed significant gains in genetic manipulation of obligate intracellular bacteria including allelic exchange. Continued development of genetic tools should soon enable routine mutation and complementation strategies for virulence factor discovery and stimulate renewed interest in these refractory pathogens. In this review, we discuss the technical challenges associated with genetic transformation of obligate intracellular bacteria and highlight advances made with individual genera.

AB The plant-associated bacterium Pseudomonas syringae pv. syringae simultaneously produces two classes of metabolites: the small cyclic lipodepsinonapeptides such as the syringomycins and the larger cyclic lipodepsipeptide syringopeptins SP22 or SP25. The syringomycins inhibit a broad spectrum of fungi (but particularly yeasts) by lipid-dependent membrane interaction. The syringopeptins are phytotoxic and inhibitory to Gram-positive bacteria. In this study, the fungicidal activities of two major syringopeptins, SP22A and SP25A, and their mechanisms of action were investigated and compared to those of syringomycin E. SP22A and SP25A were observed to inhibit the fungal yeasts Saccharomyces cerevisiae and Candida albicans although less effectively than syringomycin E. S. cerevisiae mutants defective in ergosterol and sphingolipid biosyntheses were less susceptible to SP22A and SP25A but the relative inhibitory capabilities of SRE vs. SP22A and SP25A were maintained. Similar differences were observed for capabilities to cause cellular K+ and Ca2+ fluxes in S. cerevisiae. Interestingly, in phospholipid bilayers the syringopeptins are found to induce larger macroscopic ionic conductances than syringomycin E but form single channels with similar properties. These findings suggest that the syringopeptins target the yeast plasma membrane, and, like syringomycin E, employ a lipid-dependent channel-forming mechanism of action. The differing degrees of growth inhibition by these lipodepsipeptides may be explained by differences in their hydrophobicities. The more hydrophobic 5P22A and 5P25A might interact more strongly with the yeast cell wall that would create a selective barrier for their incorporation into the plasma membrane.

DT Review
DE Francisella tularensis; antibody; complement; oxidative burst;
macrophage; dendritic cell; inflammation; suppression
AB Francisella tularensis is a highly virulent bacterial pathogen and the causative agent of tularemia. Perhaps the most impressive feature of this bacterium is its ability to cause lethal disease following inoculation of as few as 15 organisms. This remarkable virulence is, in part, attributed to the ability of this microorganism to evade, disrupt, and modulate host immune responses. The objective of this review is to discuss the mechanisms utilized by F. tularensis to evade and inhibit innate and adaptive immune responses. The capability of F. tularensis to interfere with developing immunity in the host was appreciated decades ago. Early studies in humans were the first to demonstrate the ability of F. tularensis to suppress innate immunity. This work noted that humans suffering from tularemia failed to respond to a secondary challenge of endotoxin isolated from unrelated bacteria. Further, anecdotal observations of individuals becoming repeatedly infected with virulent strains of F. tularensis suggests that this bacterium also interferes with the generation of adequate adaptive immunity. Recent advances utilizing the mouse model for in vivo studies and human cells for in vitro work have identified specific bacterial and host compounds that play a role in mediating ubiquitous suppression of the host immune response. Compilation of this work will undoubtedly aid in enhancing our understanding of the myriad of mechanisms utilized by virulent F. tularensis for successful infection, colonization, and pathogenesis in the mammalian host.

polyamines
AB The Legionella pneumophila chaperonin, high temperature protein B (HtpB), was discovered as a highly immunogenic antigen, only a few years after the identification of L. pneumophila as the causative agent of Legionnaires' disease. As its counterparts in other bacterial pathogens, HtpB did not initially receive further attention, particularly because research was focused on a few model chaperonins that were used to demonstrate that chaperonins are essential stress proteins, present in all cellular forms of life and involved in helping other proteins to fold. However, chaperonins have recently attracted increasing interest, particularly after several reports confirmed their multifunctional nature and the presence of multiple chaperonin genes in numerous bacterial species. It is now accepted that bacterial chaperonins are capable of playing a variety of protein folding-independent roles. HtpB is clearly a multifunctional chaperonin that according to its location in the bacterial cell, or in the L. pneumophila-infected cell, plays different roles. HtpB exposed on the bacterial cell surface can act as an invasion factor for non-phagocytic cells, whereas the HtpB released in the host cell can act as an effector capable of altering organelle trafficking, the organization of actin microfilaments and cell signaling pathways. The road to discover the multifunctional nature of HtpB has been exciting and here we provide a historical perspective of the key findings linked to such discovery, as well as a summary of the experimental work (old and new) performed in our laboratory. Our current understanding has led us to propose that HtpB is an ancient protein that L. pneumophila uses as a key molecular tool important to the intracellular establishment of this fascinating pathogen.

AB Experimental infection of male volunteers with Neisseria gonorrhoeae is safe and reproduces the clinical features of naturally acquired gonococcal urethritis. Human inoculation studies have helped define the natural history of experimental infection with two well-characterized strains of N. gonorrhoeae, FA1090 and MS11 mkC. The human model has proved useful for testing the importance of putative gonococcal virulence factors for urethral infection in men. Studies with isogenic mutants have improved our understanding of the requirements for gonococcal LOS structures, pill, opacity proteins, IgA1 protease, and the ability of infecting organisms to obtain iron from human transferrin and lactoferrin during uncomplicated urethritis. The model also presents opportunities to examine innate host immune responses that may be exploited or improved in development and testing of gonococcal vaccines. Here we review results to date with human experimental gonorrhea.

AB The Gram-negative bacterium Salmonella enterica has developed an array of sophisticated tools to manipulate the host cell and establish an intracellular niche, for successful propagation as a facultative intracellular pathogen. While Salmonella exerts diverse effects on its host cell, only the cell biology of the classic "trigger"-mediated invasion process and the subsequent development of the Salmonella-containing vacuole have been investigated extensively. These processes are dependent on cohorts of effector proteins translocated into host cells by two type Ill secretion systems (T3SS), although T3SS-independent mechanisms of entry may be important for invasion of certain host cell types. Recent studies into the intracellular lifestyle of Salmonella have provided new insights into the mechanisms used by this pathogen to modulate its intracellular environment. Here we discuss current knowledge of Salmonella-host interactions including invasion and establishment of an intracellular niche within the host.

AB Pneumonia is a common manifestation of the potentially fatal disease melioidosis, caused by the select agent bacteria Burkholderia pseudomaller In this study we describe a new model system to investigate pulmonary melioidosis in vivo using bioluminescent-engineered bacteria in a murine respiratory disease model. Studies were performed to validate that the stable, light producing B. pseudomallei strain JW280 constitutively produced light in biologically relevant host pathogen interactions. Hairless outbred SKH1 mice were used to enhance the ability to monitor B. pseudomallei respiratory disease, and were found to be similarly susceptible to respiratory melioidosis as BALB/c mice. This represents the first demonstration of in vivo diagnostic imaging of pulmonary melioidosis permitting the detection of B. pseudomallei less than 24 h post-infection. Diagnostic imaging of pulmonary melioidosis revealed distinct temporal patterns of bacterial colonization unique to both BALB/c and SKH1 mice. Validation of these model systems included the use of the previously characterized capsule mutant, which was found to colonize the upper respiratory tract at significantly higher levels than the wild type strain. These model systems allow for high resolution detection of bacterial pulmonary disease which will facilitate studies of therapeutics and basic science evaluation of melioidosis.

DE BST-2; tetherin; Vpu; restriction factor; HIV-1
AB The HIV-1 Vpu protein enhances the release of viral particles from the cell-surface in a cell-type specific manner. In the absence of Vpu, nascent virions remain tethered to the cell-surface in restricted cell-types. Recently, the human host factor BST-2/CD317/tetherin was found to be responsible for the inhibition of virus release. It was also reported that HIV-1 Vpu can target human BST-2 but is unable to interfere with the function of murine or simian BST-2. We performed a gain-of-function study to determine which of the differences between human and rhesus BST-2 account for the differential sensitivity to Vpu. We transferred human BST-2 sequences into rhesus BST-2 and assessed the resulting chimeras for inhibition of HIV-1 virus release and sensitivity to Vpu. We found that rhesus BST-2 carrying the transmembrane (TM) domain of human BST-2 is susceptible to HIV-1 Vpu. Finally, a single-amino-acid change in the rhesus BST-2 TM domain was sufficient to confer Vpu sensitivity.

TI GSK-3 as a target for lithium-induced neuroprotection against
excitotoxicity in neuronal cultures and animal models of ischemic stroke
SO FRONTIERS IN MOLECULAR NEUROSCIENCE
LA English
DT Review
DE lithium; glycogen synthase kinase-3; excitotoxicity; cerebral ischemia;
mesenchymal stem cells
AB The mood stabilizer lithium inhibits glycogen synthase kinase-3 (GSK-3) directly or indirectly by enhancing serine phosphorylation of both alpha and beta isoforms. Lithium robustly protected primary brain neurons from glutamate-induced excitotoxicity; these actions were mimicked by other GSK-3 inhibitors or silencing/inhibiting GSK-3 alpha and/or beta isoforms. Lithium rapidly activated Akt to enhance GSK-3 serine phosphorylation and to block glutamate-induced Akt inactivation. Lithium also up-regulated Bcl-2 and suppressed glutamate-induced p53 and Bax. Induction of brain-derived neurotrophic factor (BDNF) was required for lithium's neuroprotection to occur. BDNF promoter IV was activated by GSK-3 inhibition using lithium or other drugs, or through gene silencing/inactivation of either isoform. Further, lithium's neuroprotective effects were associated with inhibition of NMDA receptor-mediated calcium influx and down-stream signaling. In rodent ischemic models, post-insult treatment with lithium decreased infarct volume, ameliorated neurological deficits, and improved functional recovery. Up-regulation of heat-shock protein 70 and Bcl-2 as well as down-regulation of p53 likely contributed to lithium's protective effects. Delayed treatment with lithium improved functional MRI responses, which was accompanied by enhanced angiogenesis. Two GSK-3-regulated pro-angiogenic factors, matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor were induced by lithium. Finally, lithium promoted migration of mesenchymal stem cells (MSCs) by up-regulation of MMP-9 through GSK-3 beta inhibition. Notably, transplantation of lithium-primed MSCs into ischemic rats enhanced MSC migration to the injured brain regions and improved the neurological performance. Several other GSK-3 inhibitors have also been reported to be beneficial in rodent ischemic models. Together, GSK-3 inhibition is a rational strategy to combat ischemic stroke and other excitotoxicity-related brain disorders.

AB The retina transforms light entering the eye into a sophisticated neural representation of our visual world. Specialized synapses, cells, and circuits in the retina have evolved to encode luminance, contrast, motion, and other complex visual features. Although a great deal has been learned about the cellular morphology and circuitry that underlies this image processing, many of the synapses in the retina remain incompletely understood. For example, excitatory synapses in the retina feature the full panoply of glutamate receptors, but in most cases specific roles for different receptor subtypes are unclear. In this brief review, I will discuss recent progress toward understanding how Ca2+-permeable AMPA receptors (CP-GluARs) contribute to synaptic transmission and newly discovered forms of synaptic plasticity in the retina.

AB Mammalian gene expression patterns change profoundly in response to low oxygen levels. These changes in gene expression programs are strongly influenced by post-transcriptional mechanisms mediated by mRNA-binding factors: RNA-binding proteins (RBPs) and microRNAs (miRNAs). Here, we review the RBPs and miRNAs that modulate mRNA turnover and translation in response to hypoxic challenge. RBPs such as HuR (human antigen R), RIB (polypyrimidine tract-binding protein), heterogeneous nuclear ribonucleoproteins (hnRNPs), tristetraprolin, nucleolin, iron-response element-binding proteins (IRPs), and cytoplasmic polyadenylation-element-binding proteins (CPEBs), selectively bind to numerous hypoxia-regulated transcripts and play a major role in establishing hypoxic gene expression patterns. MiRNAs including miR-210, miR-373, and miR-21 associate with hypoxia-regulated transcripts and further modulate the levels of the encoded proteins to implement the hypoxic gene expression profile. We discuss the potent regulation of hypoxic gene expression by RBPs and miRNAs and their integrated actions in the cellular hypoxic response.

TI Persistency of priors-induced bias in decision behavior and the fMRI
signal
SO FRONTIERS IN NEUROSCIENCE
LA English
DT Article
DE choice; experience; expectation
AB It is well known that people take advantage of prior knowledge to bias decisions. To investigate this phenomenon behaviorally and in the brain, we acquired fMRI data while human subjects viewed ambiguous abstract shapes and decided whether a shape was of Category A (smoother) or B (bumpier). The decision was made in the context of one of two prior knowledge cues, 80/20 and 50/50. The 80/20 cue indicated that upcoming shapes had an 80% probability of being of one category, e.g., B, and a 20% probability of being of the other. The 50/50 cue indicated that upcoming shapes had an equal probability of being of either category. The ideal observer would bias decisions in favor of the indicated alternative at 80/20 and show zero bias at 50/50. We found that subjects did bias their decisions in the predicted direction at 80/20 but did not show zero bias at 50/50. Instead, at 50/50 the subjects retained biases of the same sign as their 80/20 biases, though of diminished magnitude. The signature of a persistent though diminished bias at 50/50 was also evident in fMRI data from frontal and parietal regions previously implicated in decision-making. As a control, we acquired fMRI data from naive subjects who experienced only the 50/50 stimulus distributions during both the pre-scan training and the fMRI experiment. The behavioral and fMRI data from the naive subjects reflected decision biases closer to those of the ideal observer than those of the prior knowledge subjects at 50/50. The results indicate that practice making decisions in the context of non-equal prior probabilities biases decisions made later when prior probabilities are equal. This finding may be related to the "anchoring and adjustment" strategy described in the psychology, economics, and marketing literatures, in which subjects adjust a first approximation response - the "anchor" - based on additional information, typically applying insufficient adjustment relative to the ideal observer.

DE attention; development; children; rapid serial visual processing;
attentional blink
AB The ability to direct cognitive resources to target objects despite distraction by competing information plays an important role for the development of mental aptitudes and skills. We examined developmental changes of this ability in a cross-sectional design, using the "attentional blink" (AB) paradigm. The AB is a pronounced impairment of T2 report, which occurs when a first (T1) and second target (T2) embedded in a rapid stimulus sequence are separated by at least one distractor and occur within 500 ms of each other. Two groups of children (6- to 7-year-olds and 10- to 11-year-olds; ns = 21 and 24, respectively) were asked to identify green targets in two AB tasks: one using non-linguistic symbols and the other letters or words. The temporal distance or stimulus-onset asynchrony (SOA) between T1 and T2 varied between no intervening distractor (Lag 1, 116-ms SOA) and up to 7 intervening distractors (Lag 8, 928-ms SOA). In the symbol task, younger children linearly increased T2 identification with increasing lag. Older children, however, displayed a hook-shaped pattern as typically seen in adults, with lowest identification reports in T2 symbols at the critical blink interval (Lag 2, 232-ms SOA), and a slight performance gain for the Lag 1 condition. In the verbal task, the older group again exhibited a prominent drop in T2 identification at Lag 2, whereas the younger group showed a more alleviated and temporally diffuse AB impairment. Taken together, this pattern of results suggests that the control of attention allocation and/or working memory consolidation of targets among distractors represents a cognitive skill that emerges during primary school age.

AB In this study, we focus our investigation on task-specific cognitive modulation of early cortical auditory processing in human cerebral cortex. During the experiments, we acquired whole-head magnetoencephalography data while participants were performing an auditory delayed-match-to-sample (DMS) task and associated control tasks. Using a spatial filtering beamformer technique to simultaneously estimate multiple source activities inside the human brain, we observed a significant DMS-specific suppression of the auditory evoked response to the second stimulus in a sound pair, with the center of the effect being located in the vicinity of the left auditory cortex. For the right auditory cortex, a non-invariant suppression effect was observed in both DMS and control tasks. Furthermore, analysis of coherence revealed a beta band (12 similar to 20 Hz) DMS-specific enhanced functional interaction between the sources in left auditory cortex and those in left inferior frontal gyrus, which has been shown to be involved in short-term memory processing during the delay period of DMS task. Our findings support the view that early evoked cortical responses to incoming acoustic stimuli can be modulated by task-specific cognitive functions by means of frontal-temporal functional interactions.

AB Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are two major types of skin cancer derived from keratinocytes. SCC is a more aggressive type of cancer than BCC in humans. One significant difference between SCC and BCC is that SCC development is generally associated with cell dedifferentiation and morphological changes. When SCC is converted to spindle cell carcinoma, the latest stage of cancer, the tumor cells change to a fibroblastic cell morphology (epithelial-to-mesenchymal transition) and lose their differentiation markers. Recently, several laboratories have reported altered I kappa B kinase alpha (IKK alpha) protein localization, downregulated IKK alpha, and IKK alpha gene deletions and mutations in human SCCs of the skin, lung, esophagus, and neck and head. In addition, IKK alpha reduction promotes chemical carcinogen- and ultraviolet B-induced skin carcinogenesis, and IKK alpha deletion in keratinocytes causes spontaneous skin SCCs, but not BCCs, in mice. Thus, IKK alpha emerges as a bona fide skin tumor suppressor. In this article, we will discuss the role of IKK alpha in skin SCC development.

TI A regressed phase analysis for coupled joint systems
SO GAIT & POSTURE
LA English
DT Article
DE Joint coupling; Kinematics; Gait; Phase analysis; Cerebral palsy
ID INTERJOINT COORDINATION; GAIT
AB This study aims to address shortcomings of the relative phase analysis, a widely used method for assessment of coupling among joints of the lower limb. Goniometric data from 15 individuals with spastic diplegic cerebral palsy were recorded from the hip and knee joints during ambulation on a flat surface, and from a single healthy individual with no known motor impairment, over at least 10 gait cycles. The minimum relative phase (MRP) revealed substantial disparity in the timing and severity of the instance of maximum coupling, depending on which reference frame was selected: MRP(knee-hip) differed from MRP(hip-knee) by 16.1 +/- 14% of gait cycle and 50.6 +/- 77% difference in scale. Additionally, several relative phase portraits contained discontinuities which may contribute to error in phase feature extraction. These vagaries can be attributed to the predication of relative phase analysis on a transformation into the velocity-position phase plane, and the extraction of phase angle by the discontinuous arctangent operator. Here, an alternative phase analysis is proposed, wherein kinematic data is transformed into a profile of joint coupling across the entire gait cycle. By comparing joint velocities directly via a standard linear regression in the velocity-velocity phase plane, this regressed phase analysis provides several key advantages over relative phase analysis including continuity, commutativity between reference frames, and generalizability to many-joint systems.

AB BACKGROUND & AIMS: Idiopathic gastroparesis (IG) is a common but poorly understood condition with significant morbidity. We studied characteristics of patients with IG enrolled in the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium Registry. METHODS: Data from medical histories, symptom questionnaires, and 4-hour gastric emptying scintigraphy studies were obtained from patients with IG. RESULTS: The mean age of 243 patients with IG studied was 41 years; 88% were female, 46% were overweight, 50% had acute onset of symptoms, and 19% reported an initial infectious prodrome. Severe delay in gastric emptying (>35% retention at 4 hours) was present in 28% of patients. Predominant presenting symptoms were nausea (34%), vomiting (19%), an abdominal pain (23%). Women had more severe nausea, satiety, constipation, and overall gastroparesis symptoms. Patients who experienced acute-onset IG had worse nausea than those with insidious onset. Overweight patients had more bloating and gastric retention at 2 hours but less severe loss of appetite. Patients with severely delayed gastric emptying had worse vomiting and more severe loss of appetite and overall gastroparesis symptoms. Severe anxiety and depression were present in 36% and 18%, respectively. A total of 86% met criteria for functional dyspepsia, primarily postprandial distress syndrome. CONCLUSIONS: IG is a disorder that primarily affects young women, beginning acutely in 50% of cases; unexpectedly, many patients are overweight. Severe delay in gastric emptying was associated with more severe symptoms of vomiting and loss of appetite. IG is a diverse syndrome that varies by sex, body mass, symptom onset, and delay in gastric emptying.

AB BACKGROUND & AIMS: The cytokine interleukin (IL)-10 is required to maintain immune homeostasis in the gastrointestinal tract. IL-10 null mice spontaneously develop colitis or are more susceptible to induction of colitis by infections, drugs, and autoimmune reactions. IL-13 regulates inflammatory conditions; its activity might be compromised by the IL-13 decoy receptor (IL-13R alpha 2). METHODS: We examined the roles of IL-13 and IL-13R alpha 2 in intestinal inflammation in mice. To study the function of IL-13R alpha 2, il10(-/-) mice were crossed with il13r alpha 2(-/-) to generate il10(-/-) il13r alpha 2(-/-) double knockout (dKO) mice. Colitis was induced with the gastrointestinal toxin piroxicam or Trichuris muris infection. RESULTS: Induction of colitis by interferon (IFN)-gamma or IL-17 in IL-10 null mice requires IL-13R alpha 2. Following exposure of il10(-/-) mice to piroxicam or infection with T muris, production of IL-13R alpha 2 increased, resulting in decreased IL-13 bioactivity and increased inflammation in response to IFN-gamma or IL-17A. In contrast to il10(-/-) mice, dKO mice were resistant to piroxicam-induced colitis; they also developed less severe colitis during chronic infection with T muris infection. In both models, resistance to IFN-gamma and IL-17-mediated intestinal inflammation was associated with increased IL-13 activity. Susceptibility to colitis was restored when the dKO mice were injected with monoclonal antibodies against IL-13, confirming its protective role. CONCLUSIONS: Colitis and intestinal inflammation in IL10(-/-) mice results from IL-13R alpha 2-mediated attenuation of IL-13 activity. In the absence of IL-13R alpha 2, IL-13 suppresses proinflammatory Th1 and Th17 responses. Reagents that block the IL-13 decoy receptor IL-13R alpha 2 might be developed for inflammatory bowel disease associated with increased levels of IFN-gamma and IL-17.

AB Both mouse and human mammary glands contain stem/progenitor functional hierarchies that are maintained through the entire life span of the animal. Cells with such functional capacities are potential candidates for tumorigenesis as they are long lived, multipotent, and self-renewing. Using the mouse as a model, this review will discuss what is known about the mammary stem/progenitor hierarchy, the evidence that particular progenitor functions are susceptible to tumorigenic stimuli, how these findings in mice are relevant to the disease in humans, and the role of the local microenvironment in controlling tumorigenesis.

AB Previously (Shan et al, 2005), we reported that adenoviral vector-mediated transfer of the human aquaporin-1 (hAQP1) cDNA to minipig parotid glands following irradiation (IR) transiently restored salivary flow to near normal levels. This study evaluated a serotype 2, adeno-associated viral (AAV2) vector for extended correction of IR (single dose; 20 Gy)-induced, parotid salivary hypofunction in minipigs. At 16 weeks following the IR parotid salivary flow decreased by 85-90%. AAV2hAQP1 administration at week 17 transduced only duct cells and resulted in a dose-dependent increase in salivary flow to similar to 35% of pre-IR levels (to similar to 1ml per 10 min) after 8 weeks (peak response). Administration of a control AAV2 vector or saline was without effect. Little change was observed in clinical chemistry and hematology values after AAV2hAQP1 delivery. Vector-treated animals generated high anti-AAV2 neutralizing antibody titers by week 4 (similar to 1:1600) and significant elevations in salivary (similar to 15%), but not serum, granulocyte macrophage colony-stimulating factor levels. Following vector administration, salivary [Na+] was dramatically increased, from similar to 10 to similar to 55 mM (at 4 weeks) and finally to 39 mM (8 weeks). The findings demonstrate that localized delivery of AAV2hAQP1 to IR-damaged parotid glands leads to increased fluid secretion from surviving duct cells, and may be useful in providing extended relief of salivary hypofunction in previously irradiated patients.

AB The vascular form of the Ehlers-Danlos syndrome (vEDS) is a rare inherited connective tissue disorder. Patients have a reduced life span (under 50) due to spontaneous and often fatal rupture of blood vessels and hollow organs. Until very recently no evidence-based treatment had been available. VEDS results from mutations in the COL3A1 gene that encodes the chains of collagen type III and alters the sequence in the triple-helical domain. A mouse model of vEDS created by inactivation of the Col3a1 gene has been of limited use as only 5% of homozygous animals survived to adulthood.
The haploinsufficiency for one COL3A1 allele is one of the genotypes resulting in vEDS. In this review we provide evidence that haploinsufficiency for Col3a1 in mice recapitulates features of vEDS in humans and might be used as an experimental model. There was a reduced level of aortic collagen and correspondingly reduced aortic wall strength. A spectrum of lesions was detected in the aorta similar to those observed in human patients. Lesions increased in number and age and were more common in male than in female mice.
Furthermore, potential treatment strategies are discussed including the already tested beta-adrenergic receptor (AR)-blocker therapy, the inhibition of extracellular matrix degrading enzymes, and the only causative approach of selective silencing of the mutant form of COL3A1 by allele-specific RNA interference.

AB Dyskeratosis congenita (DC) is a genetic disorder of defective tissue maintenance and cancer predisposition caused by short telomeres and impaired stem cell function. Telomerase mutations are thought to precipitate DC by reducing either the catalytic activity or the overall levels of the telomerase complex. However, the underlying genetic mutations and the mechanisms of telomere shortening remain unknown for as many as 50% of DC patients, who lack mutations in genes controlling telomere homeostasis. Here, we show that disruption of telomerase trafficking accounts for unknown cases of DC. We identify DC patients with missense mutations in TCAB1, a telomerase holoenzyme protein that facilitates trafficking of telomerase to Cajal bodies. Compound heterozygous mutations in TCAB1 disrupt telomerase localization to Cajal bodies, resulting in misdirection of telomerase RNA to nucleoli, which prevents telomerase from elongating telomeres. Our findings establish telomerase mislocalization as a novel cause of DC, and suggest that telomerase trafficking defects may contribute more broadly to the pathogenesis of telomere-related disease.

AB Two UV-sensitive syndrome patients who have mild photosensitivity without detectable somatic abnormalities lack detectable Cockayne syndrome group B (CSB) protein because of a homozygous null mutation in the CSB gene. In contrast, mutant CSB proteins are produced in CS-B patients with the severe somatic abnormalities of Cockayne syndrome and photosensitivity. It is known that the piggyBac transposable element derived 3 is integrated within the CSB intron 5, and that CSB-piggyBac transposable element derived 3 fusion (CPFP) mRNA is produced by alternative splicing. We found that CPFP or truncated CSB protein derived from CPFP mRNA was stably produced in CS-B patients, and that wild-type CSB, CPFP, and truncated CSB protein interacted with DNA topoisomerase I. We also found that CPFP inhibited repair of a camptothecin-induced topoisomerase I-DNA covalent complex. The inhibition was suppressed by the presence of wild-type CSB, consistent with the autosomal recessive inheritance of Cockayne syndrome. These results suggested that reduced repair of a DNA topoisomerase I-DNA covalent complex because of truncated CSB proteins is involved in the pathogenesis of CS-B.

AB Introduction: Genetic discoveries are validated through the meta-analysis of genome-wide association scans in large international consortia. Because environmental variables may interact with genetic factors, investigation of differing genetic effects for distinct levels of an environmental exposure in these large consortia may yield additional susceptibility loci undetected by main effects analysis. We describe a method of joint meta-analysis (JMA) of SNP and SNP by Environment (SNP x E) regression coefficients for use in gene-environment interaction studies. Methods: In testing SNP x E interactions, one approach uses a two degree of freedom test to identify genetic variants that influence the trait of interest. This approach detects both main and interaction effects between the trait and the SNP. We propose a method to jointly meta-analyze the SNP and SNP x E coefficients using multivariate generalized least squares. This approach provides confidence intervals of the two estimates, a joint significance test for SNP and SNP x E terms, and a test of homogeneity across samples. Results: We present a simulation study comparing this method to four other methods of meta-analysis and demonstrate that the JMA performs better than the others when both main and interaction effects are present. Additionally, we implemented our methods in a meta-analysis of the association between SNPs from the type 2 diabetes-associated gene PPARG and log-transformed fasting insulin levels and interaction by body mass index in a combined sample of 19,466 individuals from five cohorts.

ID ASSOCIATION
AB Group 14 of Genetic Analysis Workshop 17 examined several issues related to analysis of complex traits using DNA sequence data. These issues included novel methods for analyzing rare genetic variants in an aggregated manner (often termed collapsing rare variants), evaluation of various study designs to increase power to detect effects of rare variants, and the use of machine learning approaches to model highly complex heterogeneous traits. Various published and novel methods for analyzing traits with extreme locus and allelic heterogeneity were applied to the simulated quantitative and disease phenotypes. Overall, we conclude that power is (as expected) dependent on locus-specific heritability or contribution to disease risk, large samples will be required to detect rare causal variants with small effect sizes, extreme phenotype sampling designs may increase power for smaller laboratory costs, methods that allow joint analysis of multiple variants per gene or pathway are more powerful in general than analyses of individual rare variants, population-specific analyses can be optimal when different subpopulations harbor private causal mutations, and machine learning methods may be useful for selecting subsets of predictors for follow-up in the presence of extreme locus heterogeneity and large numbers of potential predictors.

AB Genetics Analysis Workshop 17 provided common and rare genetic variants from exome sequencing data and simulated binary and quantitative traits in 200 replicates. We provide a brief review of the machine learning and regression-based methods used in the analyses of these data. Several regression and machine learning methods were used to address different problems inherent in the analyses of these data, which are high-dimension, low-sample-size data typical of many genetic association studies. Unsupervised methods, such as cluster analysis, were used for data segmentation and, subset selection. Supervised learning methods, which include regression-based methods (e.g., generalized linear models, logic regression, and regularized regression) and tree-based methods (e.g., decision trees and random forests), were used for variable selection (selecting genetic and clinical features most associated or predictive of outcome) and prediction (developing models using common and rare genetic variants to accurately predict outcome), with the outcome being case-control status or quantitative trait value. We include a discussion of cross-validation for model selection and assessment, and a description of available software resources for these methods. Genet. Epidemiol. 35:S5S11, 2011.

AB Next-generation sequencing of large numbers of individuals presents challenges in data preparation, quality control, and statistical analysis because of the rarity of the variants. The Genetic Analysis Workshop 17 (GAW17) data provide an opportunity to survey existing methods and compare these methods with novel ones. Specifically, the GAW17 Group 2 contributors investigate existing and newly proposed methods and study design strategies to identify rare variants, predict functional variants, and/or examine quality control. We introduce the eight Group 2 papers, summarize their approaches, and discuss their strengths and weaknesses. For these investigations, some groups used only the genotype data, whereas others also used the simulated phenotype data. Although the eight Group 2 contributions covered a wide variety of topics under the general idea of identifying rare variants, they can be grouped into three broad categories according to their common research interests: functionality of variants and quality control issues, family-based analyses, and association analyses of unrelated individuals. The aims of the first subgroup were quite different. These were population structure analyses that used rare variants to predict functionality and examine the accuracy of genotype calls. The aims of the family-based analyses were to select which families should be sequenced and to identify high-risk pedigrees; the aim of the association analyses was to identify variants or genes with regression-based methods. However, power to detect associations was low in all three association studies. Thus this work shows opportunities for incorporating rare variants into the genetic and statistical analyses of common diseases. Genet. Epidemiol. 35:S22S28, 2011. (C) 2011 Wiley Periodicals, Inc.

AB Genetic Analysis Workshop 17 (GAW17) focused on the transition from genome-wide association study designs and methods to the study designs and statistical genetic methods that will be required for the analysis of next-generation sequence data including both common and rare sequence variants. In the 166 contributions to GAW17, a wide variety of statistical methods were applied to simulated traits in population- and family-based samples, and results from these analyses were compared to the known generating model. In general, many of the statistical genetic methods used in the population-based sample identified causal sequence variants (SVs) when the estimated locus-specific heritability, as measured in the population-based sample, was greater than about 0.08. However, SVs with locus-specific heritabilities less than 0.03 were rarely identified consistently. In the family-based samples, many of the methods detected SVs that were rarer than those detected in the population-based sample, but the estimated locus-specific heritabilities for these rare SVs, as measured in the family-based samples, were substantially higher (>0.2) than their corresponding heritabilities in the population-based samples. Substantial inflation of the type I error rate was observed across a wide variety of statistical methods. Although many of the contributions found little inflation in type I error for Q4, a trait with no causal SVs, type I error rates for Q1 and Q2 were well above their nominal levels with the inflation for Q1 being higher than that for Q2. It seems likely that this inflation in type I error is due to correlations among SVs. Genet. Epidemiol. 35:S107S114, 2011. (C) 2011 Wiley Periodicals, Inc.

AB Purine nucleotides are structural components of the genetic material, function as phosphate donors, participate in cellular signaling, are cofactors in enzymatic reactions, and constitute the main carriers of cellular energy. Thus, imbalances in A/G nucleotide biosynthesis affect nearly the whole cellular metabolism and must be tightly regulated. We have identified a substitution mutation (G388D) that reduces the activity of the GMP synthase Gua1 in budding yeast and the total G-nucleotide pool, leading to precipitous reductions in the GDP/GTP ratio and ATP level in vivo. gua1-G388D strongly reduces the rate of growth, impairs general protein synthesis, and derepresses translation of GCN4 mRNA, encoding a transcriptional activator of diverse amino acid biosynthetic enzymes. Although processing of pre-tRNAi(Met) and other tRNA precursors, and the aminoacylation of tRNAi(Met) are also strongly impaired in gua1-G388D cells, tRNAi(Met)-containing complexes with the macromolecular composition of the eIF2.tRNAi(Met). GTP complex (TC) and the multifactor complex (MFC) required for translation initiation accumulate similar to 10-fold in gua1-G388D cells and, to a lesser extent, in wild-type (WT) cells treated with 6-azauracil (6AU). Consistently, addition of an external supply of guanine reverts all the phenotypes of gua1-G388D cells, but not those of gua1-G388D Delta hpt1 mutants unable to refill the internal GMP pool through the salvage pathway. These and other findings suggest that a defect in guanine nucleotide biosynthesis evokes a reduction in the rate of general protein synthesis by impairing multiple steps of the process, disrupts the gene-specific reinitiation mechanism for translation of GCN4 mRNA and has far-reaching effects in cell biology and metabolism.
