TY - JOUR T1 - Lupus-prone mice as models to study xenobiotic-induced acceleration of systemic autoimmunity. AN - 21267722; 11702213 AB - The linkage between xenobiotic exposures and autoimmune diseases remains to be clearly defined. However, recent studies have raised the possibility that both genetic and environmental factors act synergistically at several stages or checkpoints to influence disease pathogenesis in susceptible populations. These observations predict that individuals susceptible to spontaneous autoimmunity should be more susceptible following xenobiotic exposure by virtue of the presence of predisposing background genes. To test this possibility, mouse strains with differing genetic susceptibility to murine lupus were examined for acceleration of autoimmune features characteristic of spontaneous systemic autoimmune disease following exposure to the immunostimulatory metals nickel and mercury. Although NiCl(2) exposure did not exacerbate autoimmunity, HgCl(2) significantly accelerated systemic disease in a strain-dependent manner. Mercury-exposed (NZB X NZW)F1 mice had accelerated lymphoid hyperplasia, hypergammaglobulinemia, autoantibodies, and immune complex deposits. Mercury also exacerbated immunopathologic manifestations in MRL+/+ and MR -lpr mice. However, there was less disease acceleration in lpr mice compared with MRL+/+ mice, likely due to the fact that environmental factors are less critical for disease induction when there is strong genetic susceptibility. Non-major histocompatibility complex genes also contributed to mercury-exacerbated disease, as the nonautoimmune AKR mice, which are H-2 identical with the MRL, showed less immunopathology than either the MRL/lpr or MRL+/+ strains. This study demonstrates that genetic susceptibility to spontaneous systemic autoimmunity can be a predisposing factor for HgCl(2)-induced exacerbation of autoimmunity. Such genetic predisposition may have to be considered when assessing the immunotoxicity of xenobiotics. Additional comparative studies using autoimmune-prone and nonautoimmune mice strains with different genetic backgrounds will help determine the contribution that xenobiotic exposure makes in rendering sensitive populations susceptible to autoimmune diseases.

AN - 21263105; 11702214 AB - A great deal of circumstantial evidence has linked iodine with the rising incidence of autoimmune thyroiditis in the United States. In our investigations, we have shown directly that T cells from humans with chronic lymphocytic thyroiditis proliferate in the presence of iodinated but not in the presence of noniodinated human thyroglobulin. Moreover, the proliferative response is restored when the thyroglobulin is iodinated artificially in vitro. Using a panel of monoclonal antibodies, we found evidence that the presence of iodine induces a number of stereochemical changes in the conformation of the molecule, resulting in the loss of some antigenic determinants and the appearance of others. One prominent determinant was associated with the iodine-containing amino acid thyroxine. Both the number and position of the iodine substituents determine the precise specificity of this epitope. A new model for the study of the role of iodine in inducing thyroid autoimmunity has become available in the form of the nonobese diabetic (NOD)-H2(h4) mouse. This animal develops autoimmune thyroiditis spontaneously but in relatively low prevalence. However, if iodine is added to the drinking water, the prevalence and severity of the thyroid lesions increase markedly. The immune response is specific for thyroglobulin, both in terms of the antibody response and T-cell proliferation. In fact, the appearance of lesions can be predicted by the presence of thyroglobulin-specific IgG2b antibody. The disease, moreover, can be transferred adoptively, using spleen cells from iodine-fed donors treated in vitro with iodinated thyroglobulin. The effects of iodine feeding are greater in conventional animals compared with those maintained under specific pathogen-free conditions. Based on T-cell proliferation, it appears that the NOD-H2(h4) strain of mice has innately a greater response to murine thyroglobulin than do other mouse strains and that the proliferation is increased even more by feeding iodine. We suggest, therefore, that the presence of iodine increases the autoantigenic potency of thyroglobulin, a major pathogenic antigen in the induction of autoimmune thyroiditis. This animal model provides a unique opportunity for investigating in detail the mechanisms by which an environmental agent can trigger a pathogenic autoimmune response in a susceptible host.

AN - 21250923; 11703774 AB - Autoimmune diseases are influenced by multiple factors including genetics, age, gender, reproductive status, hormones, and potential environmental contaminants. A workshop, "Linking Environmental Agents and Autoimmune Diseases," was convened at the National Institute of Environmental Health Sciences, Research Triangle Park, North Carolina, 1-3 September 1998, to review current knowledge about links between environmental exposures and autoimmune disease, to identify and prioritize research needs, and to develop an integrated, multidisciplinary research agenda. Participants spent the last half-day of the workshop in small group discussions for the purpose of developing consensus on research needs. Research needs identified were a) develop research tools needed to explore links between environmental agents and autoimmune disease; b) establish a disease registry or surveillance system; c) develop and validate strategies for screening chemicals for the potential to induce or exacerbate autoimmune disease; d) develop an emergency response strategy to gain information from accidental exposures; and e) conduct hypothesis-driven research in occupationally exposed groups and/or in experimental animals. There was consensus that meetings like this workshop and projects that facilitate interactions between specialties should be encouraged. A multidisciplinary approach is needed to address this problem.

AN - 21250690; 11703775 AB - Reports in humans and rodents indicate that immune development may be altered following perinatal exposure to immunotoxic compounds, including chemotherapeutics, corticosteroids, polycyclic hydrocarbons, and polyhalogenated hydrocarbons. Effects from such exposure may be more dramatic or persistent than following exposure during adult life. For example, prenatal exposure to the insecticide chlordane or to the polycyclic aromatic hydrocarbon benzo[(italic)a(/italic)]pyrene produces what appears to be lifelong immunosuppression in mice. Whether prenatal immunotoxicant exposure may predispose the organism to postnatal autoimmune disease remains largely unknown. In this regard, the therapeutic immunosuppressant cyclosporin A (CsA) crosses the placenta poorly. However, lethally irradiated rodents exposed to CsA postsyngeneic bone marrow transplant (i.e., during re-establishment of the immune system) develop T-cell-mediated autoimmune disease, suggesting this drug may produce a fundamental disruption in development of self-tolerance by T cells. The environmental contaminant 2,3,7, 8-tetrachlorodibenzo-(italic)p(/italic)-dioxin (TCDD) crosses the placenta and produces fetal thymic effects (italic)in vivo(/italic) similar to effects of CsA in fetal thymic organ culture, including inhibited thymocyte maturation and reduced expression of thymic major histocompatability complex class II molecules. These observations led to the suggestion that gestational exposure to TCDD may interfere with normal development of self-tolerance. Possibly supporting this hypothesis, when mice predisposed to development of autoimmune disease were treated with TCDD during gestation, postnatal autoimmunity was exacerbated. Similar results have been reported for mice exposed to diethylstilbestrol during development. These reports suggest that prenatal exposure to certain immunotoxicants may play a role in postnatal expression of autoimmunity.

AN - 21250577; 11702210 AB - Hexachlorobenzene (HCB) is a persistent environmental pollutant. The toxicity of HCB has been extensively studied after an accidental human poisoning in Turkey and more recently it has been shown that HCB has immunotoxic properties in laboratory animals and probably also in man. Oral exposure of rats to HCB showed stimulatory effects on spleen and lymph node weights and histology, increased serum IgM levels, and an enhancement of several parameters of immune function. Moreover, more recent studies indicate that HCB-induced effects in the rat may be related to autoimmunity. In Wistar rats exposed to HCB, IgM antibodies against several autoantigens were elevated; in the Lewis rat, HCB differently modulated two experimental models of autoimmune disease. Oral exposure of rats to HCB induces skin and lung pathology in the rat. Recently several studies have been conducted to investigate whether these skin and lung lesions can be related to HCB-induced immunomodulation, and these studies will be discussed in this review. HCB-induced skin and lung lesions probably have a different etiology; pronounced strain differences and correlation of skin lesions with immune parameters suggest a specific involvement of the immune system in HCB-induced skin lesions. The induction of lung lesions by HCB was thymus independent. Thymus-dependent T cells were not likely to be required for the induction of skin lesions, although T cells enhanced the rate of induction and the progression of the skin lesions. No deposition of autoantibodies was observed in nonlesional or lesional skin of HCB-treated rats. Therefore, we concluded that it is unlikely that the mechanism by which most allergic or autoimmunogenic chemicals work, i.e., by binding to macromolecules of the body and subsequent T- and B-cell activation, is involved in the HCB-induced immunopathology in the rat. Such a thymus-independent immunopathology is remarkable, as HCB strongly modulates T-cell-mediated immune parameters. This points at a very complex mechanism and possible involvement of multiple factors in the immunopathology of HCB.

One of the environmental concerns for this basin is erosion and its effects on downstream water quality. Models that relate climate, land use, and these concerns require measurements of climate (rainfall and temperature) and streamflow. These measurements were examined as a preliminary to the modelling. The residual mass technique was used to examine the temporal variation of annual rainfalls over the approximately 100 years of available data, and significant spatial variations were found in annual rainfall trends over the catchment. Streamflow was examined at key river gauging stations. The impact of recent large-scale irrigation operations was clearly observed. The impact of changing land use and land management on runoff ratios was examined for eight subcatchments. Temperature variations were examined for the four major towns in the catchment. The duration of the temperature data is too short to make any comments about long-term trends. Significant variations were observed in an east to west direction.

This work was conducted for the purpose of analysing competing demands for water in the Basin. The methodology described is largely driven by two issues. Firstly, the spatial relationships between river headwaters need to be captured in conjunction with any temporal correlations that may exist (adding to the complexity is the fact that some river headwaters have no flows for consecutive months). The second issue requires selecting a robust methodology which can be used within a large-scale simulation framework.

In a dose-response trial, Novodor was very effective at killing 1st instars. However, older larvae showed an increasing tolerance to the toxin that was not proportional to their body weight. At 20 degree C, maximum mortality occurred at 4 d after treatment, although further natural mortality occurred until adult emergence. Novodor also prolonged the larval development time but deterred feeding by all stages of the surviving larvae. A Bt variety tenebrionis-based insecticide shows potential for inclusion in the IPM program with appropriate monitoring to identify when the majority of the population is at 1st-instar stage. Its feasibility would be enhanced if the toxicity to older larvae could be improved.

Design: A total of 26 cervicovaginal lavage specimens collected from 17 women were used in this study to determine if HIF was significantly associated with features consistent with bacterial vaginosis. Methods: Patients were evaluated for various clinical features including age, HIV status and stage, CD4 cell counts, clinical diagnosis of gynecological infections, vaginal pH, Gram stains of vaginal fluid, phase of menstruation, and presence of cervical dysplasia. Cervicovaginal lavage specimens were analyzed for the presence of HIF by U1 bioassay. The presence of Gardnerella vaginalis, and general Mycoplasmataceae, and specifically Mycoplasma hominis, Ureaplasma urealyticum, M. fermentans, M. genitalium in cervicovaginal lavage were determined by semi-quantitative PCR. Results: Eleven cervicovaginal lavage samples from seven women were HIF-positive and 15 cervicovaginal lavage samples from 11 women were HIF-negative (patient No. 8 had two HIF-negative cervicovaginal lavage and one HIF-positive cervicovaginal lavage). The following parameters were significantly associated with HIF: abnormal vaginal fluid pH (> 4.5) (P = 0.006), Gram stains indicative of bacterial vaginosis (P = 0.007), normal menstrual cycle (P = 0.0007) and PCR detection and relative quantity of M. hominis (P = 0.0003, P = 0.002). Conclusions: This study indicates that HIF is closely associated with features of bacterial vaginosis.

Recent developments in vegetation theory and associated statistical modelling techniques are reviewed for their relevance to biodiversity. Species composition and collective properties such as species richness vary as a continuum in a multi-dimensional environmental space; a concept which needs to be incorporated into biodiversity studies. Different kinds of environmental gradients can be recognised and species responses to them vary. Species response curves of eucalypts to an environmental gradient of mean annual temperature have been shown to exhibit a particular pattern of skewed response curves. Generalised linear modelling (GLM) and generalised additive modelling (GAM) techniques are important tools for biodiversity studies. They have successfully distinguished the contribution of environmental (climatic) and spatial (history and species dispersal ability) variables in determining forest tree composition in New Zealand. Species richness studies are examined at global, regional and local scales. At all scales, direct and resource environmental gradients need to be incorporated into the analysis rather than indirect gradients e.g. latitude which have no direct physiological influence on biota. Evidence indicates that species richness at the regional scale is sensitive to environment, confounding current studies on local/regional species richness relationships. Plant community experiments require designs based on environmental gradients rather than dependent biological properties such as productivity or species richness to avoid confounding the biotic components. Neglect of climatic and other environmental gradients and the concentration on the collective properties of species assemblages has limited recent biodiversity studies. Conservation evaluation could benefit from greater use of the continuum concepts and statistical modelling techniques of vegetation ecology. The future development of ecology will depend on testing the different assumptions of competing research paradigms and a more inclusive synthesis of ecological theory.

The Aberdeen pesticides dumps site is composed of five sites located in and around the town. The participants, study areas, and questionnaire used are described. No strong evidence for an overall immunosuppressive effect of environmental exposure could be found among the Aberdeen residents. However, among subjects 1840 yr of age, Aberdeen residents were twice as likely to develop herpes zoster as were residents of nearby communities. This risk was even greater for people living in Aberdeen during the period before 1985 when pesticide-manufacturing facilities were still operating and before any remediation efforts had been initiated.

However, the historic role of medicinal herbs in the treatment and prevention of disease does not assure their safety for uncontrolled use by an uninformed public. The use of medicinal herbs in the US is described, and the concerns regarding their widespread use are elucidated. Recommendations are proposed subsequently for promoting safer practices in this area, focusing on standardization, consumer education, research into herb/drug and herb/herb interactions, research into the potential toxicity associated with high doses or prolonged use of these herbs, and identification of sensitive subpopulations.

The average nitrate concentrations in streams traversing agricultural landscapes in North America range 240 mg/l, but concentrations can exceed 100 mg/l. Studies have shown that NO sub(3) concentrations greater than 1 mg/l are toxic to amphibians, which will ultimately adversely impact amphibian prey and predators. The data suggest that it is highly probable that NO sub(3) concentrations in surface waters in North America are adversely affecting amphibian survival. While the use of vegetated buffer zones around watercourses can go a long way toward reducing the amount of NO sub(3) entering surface waters, the key to minimizing the agricultural input of NO sub(3) is the efficient use of fertilizers.

All of the subjects were second-grade schoolchildren. Results showed that most children exhibited thyroid hormone levels that were within the clinical limits of TSH and FT sub(4). Children whose thyroid hormones were outside the laboratory normal range resided more often in industrialized areas but did not exhibit a special contaminant pattern except for excessive TSH levels. Regression analysis revealed a statistically significant positive association between PCB congener 118 and TSH, while PCB congeners 138, 153, 180, 183, and 187 showed a statistically significant inverse relationship with FT sub(3). Neither blood concentration of Pb nor the urinary concentration of Hg had a statistical influence on the levels of the thyroid hormones, but the blood concentration of Cd showed an association with increasing TSH and an association with diminishing FT sub(4).

Rats were given 60 mg/kg/d of coumestrol orally, and reproductive tracts were examined after 4 d. Results showed that the trophic activity of coumestrol to the intact immature rat was evident for both wet and dry uterine weights and for wet weights of the cervix and vagina. In addition, uterine fluid inbibation was increased, accompanied by increases in total uterine hyperplasia and total uterine DNA content.

Results showed that adipose tissue and liver samples contained detectable amounts of most of the organochlorines, except for alpha -chlordane and PCB congener no. 128. p,p'-DDE, trans-nonachlor, oxychlordane, and hexachlorobenzene were the most abundant pesticides in all four tissues, while the highest PCB concentrations were noted for congeners 138, 153, 170, 180, and 187. Brain to subcutaneous fat concentration ratios were lower than one for all organochlorines, but strong correlations between the tissues were noted for specific chemicals. Liver, omental fat, and subcutaneous fat contained similar concentrations of chlorinated pesticides and their metabolites, except for beta -hexachlorocyclohexane. Concentrations of total PCBs, total DDTs, and total chlordanes in omental fat of males were not statistically different from those in females. Age was correlated only with concentrations of total PCBs.

Peroxisomes are respiratory organelles that play a role in cellular oxygen consumption as well as in production and removal of reactive oxygen species. They are also involved in a number of essential cellular functions. The function and proliferation of liver peroxisomes are described, and the effect of aging on peroxisomal metabolism is examined, including both basal peroxisomal enzyme activities and peroxisome proliferation. The mechanisms involved in the aging-related decrease in peroxisomal enzyme activities are elucidated, focusing on inherited peroxisomal disorders and the response of aging to peroxisome proliferators.

AN - 70015033; 10471806 AB - Oxygen radicals play both pathological and physiological roles in biological systems. The detection of such radicals is difficult due to their transient nature and the presence of highly efficient antioxidant mechanisms. In plants the physiological role of oxygen is twofold, oxygen is produced by the oxidation of water and consumed as an electron acceptor. The direct involvement of oxygen in photosynthetic events exposes the photosynthetic apparatus to a high probability of damage by oxygen radicals. We report here a direct, simple and rapid method for the measurement of superoxide in vitro based on voltammetric detection. It has potential applications for other in vitro systems investigating superoxide production. We show that in addition to the well established production of superoxide from photosystem I, under reducing conditions superoxide is also produced by photosystem II, probably from the Q(A) site.

ClpA directs the ATP-dependent degradation of substrate proteins bearing specific sequences, much as the 19S ATPase "cap" of eukaryotic proteasomes functions in the degradation of ubiquitination proteins. In isolation, ClpA and its relative ClpX can mediate the disassembly of oligomeric proteins; another similar eukaryotic protein, Hsp104, can dissociate low-order aggregates. ClpA has been proposed to destabilize protein structure, allowing passage of proteolysis substrates through a central channel into the ClpP proteolytic cylinder. Here we test the action of ClpA on a stable monomeric protein, the green fluorescent protein GFP, onto which has been added an 11-amino-acid carboxy-terminal recognition peptide, which is responsible for recruiting truncated proteins to ClpAP for degradation. Fluorescence studies both with and without a "trap" version of the chaperonin GroEL, which binds non-native forms of GFP, and hydrogen-exchange experiments directly demonstrate that ClpA can unfold stable, native proteins in the presence of ATP.

AN - 70790717; 10503889 AB - We previously reported findings that NADPH/cytochrome P450 reductase can generate superoxide anion radical (O2*-) from heterocyclic amines (HCA) and from many anticancer agents in vitro. Here we present more evidence in which O2*- is generated when recombinant human cytochrome b5 reductase (rh-Cytb5Rd) was incubated with HCAs such as IQ and MeIQ in the presence of NADH in vitro. This indicates that free radical generation by rh-Cytb5Rd in the presence of HCA may add new insight into the damage of DNA in addition to the previously known mechanism: interaction of activated HCA-intermediates to form DNA adduct.

Volume I: Secondary School Students. AN - 62429276; ED435070 AB - This two-volume monograph reports the results of the 24th national survey of drug use and related attitudes and beliefs among American high school seniors, the nineteenth such survey of American college students, and the eighth such survey of eighth- and tenth-grade students. The major purpose of this publication is to develop an accurate picture of current drug use and trends. Given the illicit and illegal nature of most of the phenomena under study and the absence of prevalence data, substantial misconceptions can develop and resources may be misallocated. Throughout this report, the focus in on drug use at the higher frequency levels rather than simply on who has used various drugs. A summary of the findings on trends includes: over more than a decade--from the late 1970s to the early 1990s--these were very appreciable declines in use of a number of illicit drugs among twelfth-grade students, and even larger declines in their use among American college students and young adults. These substantial improvements--which seem largely explainable in terms of changes in attitudes, beliefs about the risks of drug use, and peer norms against drug use--have some extremely important policy implications. One of these is that these various substance-using behaviors among American young people are malleable--they can be changed. Secondly, the demand-side factors appear to have been pivotal in bringing about these changes. the availability of marijuana, as reported by high school seniors, has held fairly steady throughout the life of the study. Improvements should not be taken for granted; relapse is always possible. In 1992, eighth graders exhibited a significant increase in annual use of marijuana, cocaine, LSD, and hallucinogens other than LSD, as well as an increase in inhalant use. In 1993, increases occurred in a number of "gateway drugs"--marijuana, cigarettes, and inhalants. The drug problem requires an ongoing, dynamic response from our society--one that takes into account the continuing generational replacement of our children and the generational forgetting of the dangers of drugs which can occur with that replacement.

Volume II: College Students and Young Adults. AN - 62429231; ED435071 AB - This second volume, in a two-volume set reporting the results from the Monitoring the Future study, presents the results of the 1977 through 1998 follow-up surveys of the graduating high school classes of 1976 through 1997 as they have progressed through young adulthood. This current study, which draws the college sample in the senior year of high school, has considerable advantages for generating a broadly representative sample of the college students to emerge from each graduating cohort. It has "before, during, and after" college measures, which permit the examination of change. It also has similar panel data on the high school graduates who did not attend college. In order for this volume to stand alone, some material from Volume I is repeated. Chapters 2 and 3 in this volume are the same as Chapters 2 and 3 in Volume I, since one provides an overview of the key findings and the other explains the study's design and procedures. Chapter titles include: (1) "Introduction of Volume II"; (2) "Overview of Key Findings"; (3) "Study Design and Procedures"; (4) "Prevalence of Drug Use among Young Adults"; (5) "Trends in Drug Use among Young Adults"; (6) "Attitudes and Beliefs about Drugs among Young Adults"; (7) "The Social Milieu for Young Adults"; (8) "Prevalence of Drug Use among College Students"; and (9) "Trends in Drug Use among College Students."

Vital and Health Statistics. Series 2: Data Evaluation and Methods Research. No. 128. AN - 62411360; ED436618 AB - This report summarizes current knowledge and research on the quality and reliability of death rates by race and Hispanic origin in official mortality statistics of the United States produced by the National Center for Health Statistics (NCHS). It provides a quantitative assessment of bias in death rates by race and Hispanic origin and identifies areas for targeted research. Death rates are based on information on deaths from death certificates filed in the states and compiled into a national database by NCHS, and on population data from the Census Bureau. Researchers summarized selected studies of race/Hispanic origin misclassification and undercoverage on deaths and population. They made estimates on the separate and joint bias on death rates by race and Hispanic origin from the two sources. They made simplifying assumptions about the stability of the biases over time and among age groups. Original results are presented using an expanded, updated database from the National Longitudinal Mortality Study. Death rates for all groups show net effects of race misclassification and undercoverage. For whites and blacks, published death rates are overstated in official publications by 1.0 percent and 5.0 percent, respectively, resulting mainly from undercounts in the census. Death rates for other minority groups are understated as follows: American Indians, 21 percent; Asian or Pacific Islanders: 11 percent; and Hispanics, 2 percent.

These data, and radiometric ages on the kimberlites, have been used to estimate the position of the local (paleo)geotherm and the thickness of the lithosphere, and to map the detailed distribution of specific rock types and mantle processes in space and time. A low geotherm, corresponding approximately to the 35 mW/m (super 2) conductive model of Pollack and Chapman [Tectonophysics 38, 279-296, 1977], characterised the Devonian lithosphere beneath the Magan and Anabar crustal provinces. The Devonian geotherm beneath the northern part of the area was higher, rising to near a 40 mW/m (super 2) conductive model. Areas intruded by Mesozoic kimberlites are generally characterised by this higher, but still "cratonic" geotherm. Lithosphere thickness at the time of kimberlite intrusion varied from ca. 190 to ca. 240 km beneath the Archean Magan and Anabar provinces, but was less (150-180 km) beneath the Proterozoic Olenek Province already in Devonian time. Thinner Devonian lithosphere (140 km) in parts of this area may be related to Riphean rifting. Near the northern end of the traverse, differences in geotherm, lithosphere thickness and composition between the Devonian Toluopka area and the nearby Mesozoic kimberlite fields suggest thinning of the lithosphere by ca. 50-60 km, related to Devonian rifting and Triassic magmatism. A major conclusion of this study is that the crustal terrane boundaries defined by geological mapping and geophysical data (extended from outcrops in the Anabar Shield) represent major lithospheric sutures, which continue through the upper mantle and juxtapose lithospheric domains that differ significantly in composition and rock-type distribution between 100 and 250 km depth. The presence of significant proportions of harzburgitic and depleted lherzolitic garnets beneath the Magan and Anabar provinces is concordant with their Archean surface geology. The lack of harzburgitic garnets, and the chemistry of the lherzolitic garnets, beneath most of the other fields are consistent with the Proterozoic surface rocks. Mantle sections for different terranes within the Archean portion of the craton show pronounced differences in bulk composition, rock-type distribution, metasomatic overprint and lithospheric thickness. These observations suggest that individual crustal terranes, of both Archean and Proterozoic age, had developed their own lithospheric roots, and that these differences were preserved during the Proterozoic assembly of the craton. Data from kimberlite fields near the main Archean-Proterozoic suture (the Billyakh Shear Zone) suggest that reworking and mixing of Archean and Proterozoic mantle was limited to a zone less than 100 km wide.

The system uses a modular Barnes successive correction scheme to produce the analyses, either in near-real-time or using historical datasets. The national analysis is produced on a 25 km grid with a correlation length scale of 80 km, which is appropriate for the data density across Australia. Smaller correlation lengths and finer grids can be used for regional analyses. The accuracy of the real-time system has been tested by comparing analyses obtained from the full climatological dataset collected by the National Climate Centre (NCC) with the analyses limited to the real-time data. The two datasets were also compared to obtain information about the reliability of real-time observations. These investigations have shown that over most of Australia and with few caveats, reasonably accurate analyses are obtained using real-time data. A particular problem is found to be caused by telegraphic rainfall stations that do not report in real time when they record no rain. The analysis system is used to illustrate seasonal and event-related climatological features of Australian rainfall.

Fixed-bed study AN - 17581414; 4645509 AB - The adsorption of uranium(VI) and lead(II) on fixed beds of chromatography silica gel (CSG) and desiccant silica gel (DSG) was investigated at initial pH 5.15 and an initial concentration of 0.5 and 0.1 mM for uranium(VI) and lead(II), respectively, and exhibited a constant pattern of breakthrough curves at various bed heights and flow rates. The experimental data gave a good fit to the bed depth-service time (BDST) model at 50% breakthrough with the bed capacity close to the value predicted from batch study results. The adsorption performance of the silica gel columns could be well described by the Clark model at the ratios of concentration of effluent to influent (C/C sub(0)) up to 0.3 for uranium(VI) and 0.5 for lead(II). Above these levels, the model was approximately valid for uranium(VI), while a large deviation occurred with lead(II) adsorption. Application of the Wolborska model to the data at C/C sub(0) ratios lower than 0.5 enabled the determination of the kinetic coefficients for mass transfer in these systems. Furthermore, it was found that uranium(VI) could be effectively separated from lead(II) by using a column packed either with CSG or DSG at pH 3.50. Complete removal of uranium(VI) adsorbed to a packed bed of silica gel was obtained by employing 4.5 M HNO sub(3) as eluant. Six and seven bed volumes of 4.5 M HNO sub(3) were required for the elution of uranium(VI) from CSG and DSG, respectively. For lead(II), complete desorption from the column required 3.0 and 3.5 bed volumes of 1.5 M HNO sub(3) solution for CSG and DSG, respectively. For both uranium(VI) and lead(II) it was found that the DSG-packed column exhibited better performance than CSG in terms of service time and volume of solution treated, and gave similar value of the adsorbent usage rate, suggesting that DSG can be used instead of CSG in column applications.

Adsorption and kinetics AN - 17579803; 4645510 AB - In this study desiccant silica gel (DSG) was compared with chromatography silica gel (CSG) for its ability to remove metal ions including Pb super(2+), Cu super(2+), Ni super(2+), Zn super(2+), Cd super(2+) and UO super(2) sub(2) super(+) from solution. The equilibration time was shorter for UO super(2) sub(2) super(+) (less than 1 h) than for the heavy metal ions (2-3 h) and adsorption by DSG took longer to reach equilibrium compared with CSG, probably due to the smaller mean diameter of its pores. The adsorption process showed first order kinetics for all the metals studied. The mass transfer coefficients and overall rate constants were determined for each of the metals. The adsorption rates of the metal ions, in order of decreasing magnitude, were UO super(2) sub(2) super(+) > Pb super(2+) > - Cu super(2+) > Zn super(2+) > Ni super(2+) > Cd super(2+) for both DSG and CSG. Metal uptake was found to increase rapidly within a two pH unit range characteristic for each metal. The adsorption of the metal ions obeyed the Langmuir isotherm and followed the preferential order UO super(2) sub(2) super(+) > Pb super(2+) > Cu super(2+) > Ni super(2+) > Zn super(2+) > Cd super(2+). Similarity of the isotherms for the individual metals was observed for both DSG and CSG, indicating a comparable removal capacity of DSG and its possible use as an alternative to CSG in adsorption applications. Adsorption from lead(II)-uranium(VI) solutions showed that the uptake of each metal was considerably reduced with an increasing concentration of the other, the adsorption of lead(II) being more strongly influenced by uranium(VI) than vice versa due to the higher affinity of silica gel for the latter.

From observations that increases in water level in aquaculture ponds initiate spawning in some species, and from limited studies of wild fishes and studies in overseas floodplain river systems, a perception has emerged of the importance of flooding and the flood plain in the life cycles of Murray-Darling fishes in general. However, there is little confirmatory evidence of the use of temporary floodplain habitats by larvae, juveniles or adults. The significance of in-channel habitats, especially for rearing, has received little attention. Murray-Darling fish species can be placed into three life history modes, based mainly on spawning style and time and developmental intervals of larvae at first feeding. Fish in each group may be able to take advantage of floods if the timing is right and prey are plentiful, however, the larvae of some species are able to recruit under non-flood conditions within the main river channel. This forms the basis of the `low flow recruitment hypothesis', which attempts to explain why some species spawn during the warmest months and lowest flows and how they are able to recruit under these conditions. This hypothesis is then placed in the context of the current state of knowledge of the relationships between flow and the biology of Murray-Darling fishes, specifically cues for spawning, movement and recruitment. The lack of widespread evidence for floodplain use by any life history interval of fish may be due to a paucity of study, however, there are some fundamental factors, such as the predictability of timing and duration of high flow events as well as the lack of coincidence of high flows and high temperatures in some regions of the Basin, which may be important in determining the use of floodplain habitats by fish.

Both binucleate Rhizoctonia isolates prevented growth of all Phytophthora isolates within 36 h of the paired cultures meeting. All fungal isolates produced parallel hyphae, hooks and coils on opposing cultures, except the binucleate Rhizoctonia isolates on P. citricola. In four glasshouse experiments, however, neither the binucleate Rhizoctonia nor four bicontrol bacterial isolates, consistently suppressed diseases caused by P. cryptogea or P. nicotianae var. nicotianae in tomato seedlings grown in potting medium. Only the fungicide, metalaxyl, gave satisfactory disease control against both Phytophthora spp. In a subsequent in vitro test of five fungicides at commercial doses, only metalaxyl did not inhibit growth of the two binucleate Rhizoctonia isolates. Because of the compatability of metalaxyl with the binucleate Rhizoctonia isolates, this fungicide could be used to control Phytophtora spp. in an integrated control programme with a binucleate Rhizoctonia to control the other major damping-off fungi.

A selected isolate of binucleate Rhizoctonia and two fungicides were also included as standards for control of Rhizoctonia solani and Pythium ultimum var. sporangiiferum. Both isolates of T. koningii reduced seedling death caused by R. solani in one of two experiments, and by P. u. sporangiiferum in two of three experiments. Neither isolate of T. koningii suppressed damping-off caused by either pathogen as consistently as the binucleate Rhizoctonia or fungicides. The implications of these results for commercial disease management are discussed.

The timescale of this fluctuation initially had a value approximate to 10 years, and increased to a value of about 20 years. This fluctuation is structured as a train of centers of negative and positive rainfall perturbation alternating in time. A strong positive trend in annual rainfall amount started simultaneously to excitation of amplifying fluctuation. Analyses of contribution from bands of wavelet timescale to reconstruction of time series of perturbation of annual rainfall amount indicate that trend is produced by fluctuations with timescale larger than 10 years. Before 1935, annual rainfall had a stationary mean. After that year, mean annual rainfall in this region is increasing at a rate of 5 mm/year. During the period 1935-1983, the trend produced by contribution from fluctuations with timescale greater than 10 years is 4.6 mm/year. The remaining 0.4 mm/year of trend is produced by fluctuations with timescale smaller than 10 years, and it does not have statistical significance. The amplifying fluctuation in the bands of fluctuations with timescale 10-17 years and 17-27 years, is clearly detected in the 3-month periods November to January, and February to April. These are also the only two 3-month periods with trend statistically significant. Regression analysis of seasonal rainfall on year indicates that there is a discontinuity in trend between the periods 1873-1934 and 1935-1983. In periods November to January and February to April, fluctuations with timescale larger than 10 years produce a statistically significant trend after 1935. Fluctuations with timescale smaller than 10 years do not contribute in a significant way to trend in these seasons. During the 60 years before wave excitation (period 1873-1934), wavelet analysis does not show another amplifying fluctuation of such strong intensity. Finding what triggered this gargantuan amplifying fluctuation in annual rainfall is an important question for understanding multidecadal climate variability.

Climatic change in this lake is recorded in the evaporative loss trend reconstructed from water level and lakewater salinity estimates. A decrease in salinity between similar to 700 and 200 years BP corresponds with c. 5 m increase in water level over the same time period. Both water level and lakewater salinity then stabilize in the last similar to 200 years BP. The palaeohydrological model derived from the changes inferred in salinity and water level shows that there is no significant change in evaporation for the last similar to 700 years but that a lower evaporation period is evident at similar to 150-200 years BP suggestive of a mild 'Little Ice Age' event in the Vestfold Hills.

Each animal was dosed, intragastrically, with single doses of p-cymene (0.37 mmol/kg and/or 1.49 mmol/kg). Urine and feces were collected for two 24-hr periods. Quantitative analysis of urinary metabolites by extraction, gas chromatography, and mass spectrometry gave a mean recovery of 64% (range 52-74%) of the administered dose in 48 hr for the four species. No fecal metabolites were found. A species-specific pattern of metabolite excretion was evident and reflected the natural occurrence of p-cymene (and terpenes in general) in the diet. If the metabolites excreted are grouped according to the total number of oxygen atoms added (one to four), then the rat excreted metabolites encompassing all degrees of oxidation, but predominantly a monooxygenated metabolite. The brushtail possum excreted metabolites having two, three, and four oxygen atoms added. The ringtail possum and greater glider only excreted metabolites with three or four oxygen atoms. Conjugation played a significant role in the excretion of oxidized metabolites in only the brushtail possums and the rat. These findings indicate that species encountering terpenes, such as p-cymene, in their normal diet have developed efficient oxidation pathways to eliminate them. This oxidative efficiency could also reduce the necessity for subsequent conjugation of metabolites which minimizes further demands on a nutritionally limited diet.

Willows, Salix spp., have been widely introduced as a riparian species in temperate Australia and New Zealand. The present study was a broad-scale observational survey to document the differences between reaches of river lined with willows and native vegetation in the community structure of benthic invertebrates and the resources which these plants use. 2. Nine rivers in south-eastern Tasmania were examined on three occasions in autumn, spring and summer. Taxa were identified to family level, with the exception of Oligochaeta and Acarina, and benthic organic matter (CPOM and FPOM) and epilithic biomass were measured for each reach. 3. Taxon diversity and evenness were lower in willowed reaches in autumn, and total macroinvertebrate density and number of taxa were lowest in willowed reaches in summer. No differences in the fauna between willowed and native reaches were observed in spring. Measures of community similarity of the fauna in willowed and native reaches were significantly different in autumn and summer, but not in spring. 4. The taxa responsible for the significant differences seemed to be responding to differences in food availability and habitat quality in reaches of each vegetation type. Organic matter standing stock was higher in willowed reaches in autumn although the influence of these litter inputs on the fauna were not marked. Epilithon biomass was highest in autumn and spring in willowed reaches when shading in these reaches was least. 5. The most marked differences between willowed and native reaches were during summer low flows, when the instream fauna appeared to be responding to changes to shading, water quality and the quality of the habitat.

We then asked the question: What proportion of tail species within a given community are constitutive members of the tail everywhere throughout their geographical range, versus what proportion are found as substantially more abundant somewhere within their range? Out of 55 tail species identified from dry sclerophyll woodland and 116 tail species identified from temperate rain forest, 91% and 95%, respectively, were significantly more abundant at other locations ("somewhere-abundant" species), versus 9% and 5% "everywhere-sparse" species. Among eight attributes in dry sclerophyll woodland and nine attributes in temperate rain forest compared between somewhere-abundant and everywhere-sparse species, none discriminated consistently between the two groups of species. The size and dispersal morphology of seeds, flowering and fruiting durations and seasons, regeneration strategy after fire, size of geographical ranges, maximum plant height, and size class revealed no consistent distinctions. For the small minority of species that are everywhere-sparse, some general explanation may exist as to why they are in the tail of rank-abundance curves, though none was located among the attributes compared in this paper. For the majority of tail species that are somewhere-abundant, any explanation as to why they are in the tail will need to account for different outcomes in different places.

These populations are univoltine and colonies exhibit a semisocial/quasisocial polymorphism. Synchronous brood development and restricted periods of egg laying in these populations severely limit opportunities for sib rearing by older daughters. Here, we report the life cycle and social behavior of a conspecific subcoastal heathland population from southern Victoria. Colony sizes and intracolony relatedness are lower in the heathland population, possibly because the nesting substrate is relatively short-lived and spatially dispersed. Brood development is relatively rapid at the heathland locality, such that some colonies are able to produce a 2nd brood in late summer. As a result, opportunities for sib rearing frequently occur in heathland E. robusta, allowing for quite different forms of alloparental care than occurs in montane populations. The presence of opportunities for sib-rearing behavior in this species provides evidence of habitat mediation of sociality that is not caused by latitudinal variation.

Recently, a single-strain outbreak of MRSA occurred in a WA metropolitan teaching hospital following admission of an infected patient from a remote community. The strain responsible for the outbreak was unrelated to any imported strains and spread rapidly in the hospital. Screening of two remote communities in the region from which the index case came revealed that 42% of the people in one community and 24% in the other carried MRSA. Isolates were typed by resistance pattern, plasmid analysis, contour-clamped homogeneous electric field electrophoresis, bacteriophage pattern, and coagulase gene restriction fragment length polymorphism. It was found that of the people carrying MRSA, 39% in the former community and 17% in the latter community were carrying an MRSA strain which was indistinguishable from the strain that caused the hospital outbreak.

The caged fish were rainbow trout Oncorhynchus mykiss, and the feral fish were perch Perca fluviatilis and roach Rutilus rutilus. Cytochrome P4501A induction was determined, xenobiotic metabolism was studied, and morphological changes in different tissues were detected. The contents of nine PAHs and four heavy metals were also determined in tissue samples. Results showed that the concentrations of PAHs were highest in the sediments, intermediate in aquatic biota, and lowest in the water column. The total PAH content in rainbow trout muscle ranged 421890 ng/g, while in the feral fish, concentrations ranged 14614820 and 116611,441 ng/g in muscle and liver, respectively. The dominant compounds were pyrene, chrysene, and fluoranthene. Despite the high concentrations of PAHs, however, there was no induction of mixed oxygenase activities in any of the studied fish. Glutathione activity exhibited a trend toward increased values in all species at the exposed sites, but the overall condition factor of the fish and the liver somatic index were not affected seriously by the pollutants. No clear evidence of enhanced micronuclei formation was discerned at the exposed sites.

Results showed that high As concentrations in the drilled wells were uncommon, and the median dose of inorganic As from well water was approximately 0.2 mu g/d. The data suggested an increased bladder cancer risk associated with low As exposure levels, and a statistically significant elevated risk of bladder cancer was observed for As concentrations greater than 0.5 mu g/l. No association was observed between kidney cancer and As exposure from drinking water. A synergistic effect between As and smoking, and bladder cancer was discerned.

Results are presented from a study in which 22 commercial cultivars of the species were investigated for tumor-promoting diterpenoids using high-performance liquid chromatography. The tumor-promoting potential of plant extracts was determined using an EpsteinBarr virus induction assay. Result showed that the cultivars contained a broad range of ingenol ester contents, with a mean content of 73 ng/g latex. The latex and leaf samples of Euphorbia lomii and E. leuconeura were strong tumor promoters, and there was a close correlation between EpsteinBarr virus induction and ingenol content.

Relationships between air pollution and the prevalence of bronchitis and phlegm were examined in three subgroups: children with asthma, children with wheeze only, and children with neither wheeze nor asthma. A two-stage modeling strategy was employed. Results showed that, among children with asthma, increased particulate air pollution was associated with significantly increased prevalence of chronic phlegm production and with bronchitis. There was also a strong association of nitrogen dioxide and gaseous acid with increased phlegm prevalence and a modest and nonsignificant association of NO sub(2) with increased prevalence of bronchitis. Because ambient particulate matter in Southern California was relatively low in sulfates, the increased risk among asthmatic children with lower respiratory symptoms associated with particulate exposure was not attributed to the presence of sulfur dioxide and SO sub(2)-derived sulfates.

Data from these studies were evaluated directly for statistical evidence of a threshold in lung tumor response between high and low exposure concentrations. The data below the threshold were examined for heterogeneity with respect to zero-exposure responses, and a multi-stage model was used to determine both maximum likelihood estimates and upper confidence limit estimates for the exposureresponse slope. Analysis results showed that the tumor responses observed in rats at high levels of exposure to these particles did not occur at low exposures, indicating a threshold of response ranging 160600 mu g/m super(3) continuous lifetime concentration. An upper-bound unit risk extrapolated to humans was calculated at 9.3 10 super(-6) per mu g/m super(3).

Emissions monitoring data were obtained from the plant, and cancer risk estimates with uncertainty were generated. Soil and sediment monitoring data were also examined, along with evidence of carcinogenicity and chronic Be disease. Inhalation of air was the exposure pathway of concern. Five atmospheric transport models were considered, and the RATCHET model was chosen ultimately, which uses two modeling grids. Model prediction uncertainty was accounted for by using several multiplicative stochastic correction factors in the dispersion estimate, the meteorology, and deposition and plume depletion. The extensive resulting data are presented in terms of the predicted concentrations, exposure scenarios, breathing rates and time budgets, and uncertainty. The geometric mean incremental lifetime cancer incidence risk estimates for Be inhalation were highest for ranchers and lowest for retirees, at 3.9 10 super(-10) and 7.5 10 super(-13), respectively. The estimated risks, which were a function of exposure time, exposure duration, and location of exposure, were well below the EPA point of departure for acceptable risks.

The mutagens were 2-[2-(acetylamino)-4-[bis(2-methoxyethyl)-amino]-5-methoxy phenyl]-- 5-amino-7-bromo-4-chloro-2H-benzotriazole (PBTA-1) and 2-[2-(acetylamino)-4-[N-(2-cyanoethyl)ethylamino]- 5-methoxyph- eny]-5-amino-7-bromo- 4-chloro-2H-benzotriazole (PBTA-2). Mutagenic assays were also carried out on Salmonella typhimurium. Results showed that almost all samples collected at sites downstream of two sewage plants contained detectable concentrations of both amines. All of the samples collected downstream of the plants were also found to be mutagenic.

This is because flagellar motors are powered by dissipation of ion gradients across their cell membranes. We tested how much the 2 known motor systems contributed to the high speed motility (> 100 mu m s super(-1)) found in marine bacterial communities and isolates. Monensin, carbonylcyanide-m-chlorophenylhydrozone (CCCP) and amiloride were used on Escherichia coli, Shewanella putrefaciens, Alteromonas haloplanktis, a marine isolate (BBAT1) and marine bacterial communities to uncouple sodium-ion and proton gradients from motility. E. coli motility was stopped by 10 mu M CCCP. Use of any of the 3 uncouplers alone slowed, but did not stop, S. putrefaciens, A. haloplanktis and a community of marine bacteria. A combination of 20 mu M CCCP and 20 mu M monensin stopped S. putrefaciens and A. haloplanktis. The same concentration combination reduced marine community speeds by half, but stopped few cells. Above uncoupler concentrations of 30 mu M speed remained unchanged at about 20 mu m s super(-1) for marine bacterial communities. Sodium-ion motors were responsible for about 60% of marine bacterial speed. From the results it was concluded that most high speed marine bacterial community members used sodium and proton motors simultaneously.

Death rates were measured for a combination of four growth-permissible temperatures (15 degree C, 25 degree C, 40 degree C and 45 degree C) and four distinctly lethal water activities (0.75, 0.83, 0.88 and 0.90). In addition, death rates were measured at two temperatures (4 degree C and 50 degree C) outside the growth range of E. coli. Death rate increased both at higher temperature or lower water activity. Inactivation curves resulting from exposure of E. coli to osmotic stress were biphasic. The initial rate of death was followed by a slower second phase decline, or "tailing" effect. Addition of chloramphenicol to the suspending medium reduced the tailing effect and suggested that tailing was caused by de novo protein synthesis.

It is thought to have evolved within the cyanobacterial lineage, but it has been difficult to determine when it began. Evidence based on the occurrence and appearance of stromatolites and microfossils indicates that phototrophy occurred as long ago as 3,465Myr although no definite physiological inferences can be made from these objects. Carbon isotopes and other geological phenomena, provide clues but are also equivocal. Biomarkers are potentially useful because the three domains of extant life--Bacteria, Archaea and Eukarya--have signature membrane lipids with recalcitrant carbon skeletons. These lipids turn into hydrocarbons in sediments and can be found wherever the recordis sufficiently well preserved. Here we show that 2-methylbacteriohopanepolyols occur in a high proportion of cultured cyanobacteria and cyanobacterial mats. Their 2-methylhopane hydrocarbon derivatives are abundant in organic-rich sediments as old as 2,500Myr. These biomarkers may help constrain the age of the oldest cyanobacteria and the advent of oxygenic photosynthesis. They could also be used to quantify the ecological importance of cyanobacteria through geological time.

AN - 85304770; pmid-10448736 AB - OBJECTIVE: To describe characteristics of 3-dimensional (3-D) computed tomographic (CT) endoscopic images of the larynx in unilateral vocal fold paralysis and the changes of the paralyzed vocal fold after phonosurgery as indicated by 3-D CT endoscopy. SETTING: A university medical center. PATIENTS: Twelve consecutive patients with unilateral vocal fold paralysis who underwent helical CT examination. Five of them underwent the CT examination before and after phonosurgical treatment. INTERVENTIONS: Three patients underwent arytenoid adduction, and 2 underwent type 1 thyroplasty. MAIN OUTCOME MEASURES: "Sagging," defined as caudal displacement of the vocal fold; and "thinning," defined as a decrease in the vertical thickness of the vocal fold and expansion of the ventricle on the affected side, were evaluated. RESULTS: Excessive motion artifacts in one patient prevented detailed description of his 3-D images. Sagging and thinning of the vocal fold and expansion of the ventricle on the affected side were noted on 6, 11, and 8 occasions, respectively. Adduction or augmentation of the paralyzed vocal fold after phonosurgery was observed in 3-D CT endoscopic images when displayed with bony densities. CONCLUSIONS: The use of 3-D CT endoscopy enables description of 3-D characteristics of unilateral vocal fold paralysis and supplements stroboscopic findings. Furthermore, CT endoscopic images, when simultaneously displayed with bony densities, may help in evaluating the effects of phonosurgical treatment of the paralyzed vocal fold.

AN - 70010006; 10469312 AB - We report here a patient (Ops1) with clinical photosensitivity, including pigmented or depigmented macules and patches, and multiple skin neoplasias (malignant melanomas, basal cell carcinomas, and squamous cell carcinomas in situ) in sun-exposed areas. These clinical features are reminiscent of xeroderma pigmentosum. As cells from Ops1 showed normal levels in DNA repair synthesis in vivo (unscheduled DNA synthesis and recovery of RNA synthesis after ultraviolet irradiation), we performed a postreplication repair assay and recovery of replicative DNA synthesis after ultraviolet irradiation to investigate if Ops1 cells belonged to a xeroderma pigmentosum variant pattern. Ops1 cells were normal, but there was an incomplete pattern repair in (6-4) photoproducts in contrast to a normal pattern repair in cis-syn cyclobutane pyrimidine dimers by repair kinetics using the enzyme-linked immunosorbent assay. Moreover, Ops1 cells were defective in a damage-specific DNA binding protein and carried a non-sense mutation in the DDB2 gene. These results suggest that (i) the DDB2 gene is somewhat related to skin carcinogenesis, photoaging skin, and the removal of (6-4) photoproducts; (ii) although it is believed that cyclobutane pyrimidine dimers are the principal mutagenic lesion and (6-4) photoproducts are less likely to contribute to ultraviolet-induced mutations in mammals, Ops1 is one of the ultraviolet-induced mutagenic models induced by (6-4) photoproducts.

AN - 21259616; 11703773 AB - The major concerns with endocrine disruptors in the environment are based mostly on effects that have been observed on the developing embryo and fetus. The focus of the present manuscript is on disruption of three hormonal systems: estrogens, androgens, and thyroid hormones. These three hormonal systems have been well characterized with regard to their roles in normal development, and their actions during development are known to be perturbed by endocrine-disrupting chemicals. During development, organs are especially sensitive to low concentrations of the sex steroids and thyroid hormones. Changes induced by exposure to these hormones during development are often irreversible, in contrast with the reversible changes induced by transient hormone exposure in the adult. Although it is known that there are differences in embryonic/fetal/neonatal versus adult endocrine responses, minimal experimental information is available to aid in characterizing the risk of endocrine disruptors with regard to a number of issues. Issues discussed here include the hypothesis of greater sensitivity of embryos/fetuses to endocrine disruptors, irreversible consequences of exposure before maturation of homeostatic systems and during periods of genetic imprinting, and quantitative information related to the shape of the dose-response curve for specific developmental phenomena.

AN - 21250912; 11703772 AB - The workshop "Characterizing the Effects of Endocrine Disruptors on Human Health at Environmental Exposure Levels" was held to provide a forum for discussions and recommendations of methods and data needed to improve risk assessments of endocrine disruptors. This article was produced by a working group charged with determining the basic mechanistic information that should be considered when designing models to quantitatively assess potential risks of environmental endocrine disruptors in adults. To reach this goal, we initially identified a set of potential organ system toxicities in males and females on the basis of known and/or suspected effects of endocrine disruptors on estrogen, androgen, and thyroid hormone systems. We used this integrated, systems-level approach because endocrine disruptors have the potential to exert toxicities at many levels and by many molecular mechanisms. Because a detailed analysis of all these untoward effects was beyond the scope of this workshop, we selected the specific end point of testicular function for a more detailed analysis. The goal was to identify the information required to develop a quantitative model(s) of the effects of endocrine disruptors on this system while focusing on spermatogenesis, sperm characteristics, and testicular steroidogenesis as specific markers. Testicular function was selected because it is a prototypical integrated end point that can be affected adversely by individual endocrine disruptors or chemical mixtures acting at one specific site or at multiple sites. Our specific objective was to gather the information needed to develop models in the adult organism containing functional homeostatic mechanisms, and for this reason we did not consider possible developmental toxicities. Homeostatic mechanisms have the potential to ameliorate or lessen the effects of endocrine disruptors, but these pathways are also potential target sites for the actions of these chemicals.

AN - 21245171; 7675990 AB - We used the case-crossover design to identify any increase in mortality in Seoul, Korea, when there were higher levels of ambient air pollution on case-days than would be expected solely as a result of chance. This empirical study showed that either unidirectional retrospective (selecting only control days prior to death) or prospective (selecting only control days after death) control sampling could cause risk estimates to be confounded by seasonal waves as well as time trends in air pollution levels. In bidirectional control sampling in which exposures at death were compared with exposures both before and after death, the estimated mortality was resistant to confounding by time patterns of air pollution. Using a bidirectional control sampling approach, the results from a conditional logistic regression model controlling for weather conditions showed that the nonaccidental mortality associated with a 50-ppb increment over a 3-day moving average of SO(2) concentrations, including the concurrent day and preceding 2 days, was 1.023 [95% confidence interval (CI), 1.016-1.084]. The relative risk of death was 1.023 (CI, 0.999-1.048) per 50 ppb for 1-hr maximum O(3) and 1.010 (CI, 0.988-1.032) per 100 microg/m(3 )or total suspended particulates. In conclusion, the findings of this study were 2-fold: given the consistency of the observed association between SO(2) and daily mortality across different analysis methods, the association reported here indicates that air pollution is a probable contributor to premature death; and bidirectional control sampling is needed in a case-crossover design applied to air pollution epidemiologic studies to control confounding by seasonal patterns of air pollution as well as time trends.

They use their lower incisors mainly to excavate their tunnel systems. We found that the lower incisors of the mole-rat grow significantly faster than the upper incisors. Upper and lower incisors of males grow significantly faster than incisors of females. Density of incisors of males was significantly higher than in females and in male laboratory rats (Rattus norvegicus). In both sexes of mole-rats, maxillary bone density at the root apex area of the incisor was significantly higher than the anterior area where incisors emerge from the bone and the same area densities in male laboratory rats. We suggest that the rapid growth rate and high density of incisors in mole-rats compared with male laboratory rats represent an adaptation to their digging life-style and compensate for the extensive incisor attrition resulting from the mechanical forces of digging. Intersexual differences in mole-rat incisor growth and incisor plus maxillary bone densities are in accordance with intersexual behavioral differences: males excavate wider and longer tunnels than females and are more aggressive. Because incisors of males are used more extensively in digging and fighting than those of females, we suggest that male mole-rats develop stronger incisors with a higher compensatory growth rate than females.

Mouse plagues are a significant problem to agricultural areas of Australia, causing millions of dollars of damage. This study was conducted to determine if rainfall could explain the occurrence of mouse plagues. 2. On average, data on mouse abundance were collected every month, using mark-release-recapture techniques, from the Victorian Mallee cereal-growing region, from February 1983 to October 1994. No data were collected from December 1990 to September 1992. Three plagues of mice occurred during these 12 years. We examined the rate of increase of mouse populations as a function of antecedent rainfall. 3. The highest observed rate of increase per month was during 1986 (r = 1.86). The highest observed rate of decrease per month was during 1984 (r = -2.85). The maximum rate of increase of mouse populations used in the numerical response function was 1.16 month super(-1). The best estimate for the numerical response function was r sub(obs) = -6.79 + 7.95 (1-e super(-1.11v)). 4. The numerical response of mouse populations to rainfall was examined against 6-month accumulated rainfall that was lagged by 0, 3 and 6 months. The best fit of the model was to lag rainfall by 3 months. 5. Two systems for the response of mouse populations to rainfall are described. The plague system occurred when mouse populations responded to rainfall: populations increased following high rainfall and decreased following low rainfall. The non-plague system occurred when the exponential rate of increase and rainfall were independent: populations crashed after a plague and were unable to respond to rainfall for at least 2 years thereafter. 6. The two systems suggest that there is 'biological memory' that masks the effect of rainfall for a minimum period after a mouse plague. This memory appears to be associated with the time since the last plague, the population response by mice (including shifts in age structure) in the previous year, and the abundance of mice after the spring decline. If rainfall is used to predict mouse plagues to assist in their management, the biology of the system must be known.

The ponds were operated from April to November at 0.12, 0.24 and 0.34 m depth as batch-fed reactors. Average 5-day biochemical oxygen demand (BOD sub(5)) loading was 6.24 g/m2u/d and the ponds were mixed at a mean surface velocity of 0.20 m/s. Dry matter, chlorophyll, optical density (OD sub(560)), NO sub(3), NO sub(2), NH sub(4), urea and total phosphorus were determined daily. Temperature, pH, dissolved oxygen and incident irradiance were monitored continuously. Correlation and multiple regression analyses were used to determine significant interactions between environmental factors, biomass production and nutrient removal. Both chlorophyll a and optical density were accurate predictors of dry matter biomass. All measures of pond biomass were positively correlated with elapsed time, surface daily irradiance, daylength and pH, but negatively correlated with pond depth. Significant correlations between pH and daily irradiance, maximum dissolved oxygen and forms of nitrogen (nitrite or nitrate) suggested that the final pond pH represents an equilibrium between alkalization by photosynthesis and acidification by nitrification. Total nitrogen removal was influenced by biomass, elapsed time, temperature and daily irradiance, but not by either pH or depth. The concentration of ammonium nitrogen (NH sub(4)-N) was inversely correlated with temperature, biomass, depth, daily irradiance and daylength. Nitrification was found to occur with nitrate concentration showing a strong negative correlation with daylength, reflecting an increase in nitrifying activity by the pond biomass throughout the season. Nitrate concentrations were positively correlated with elapsed time, but negatively correlated with biomass, temperature and daily irradiance. Phosphorus removal was influenced by elapsed time and biomass concentration. Removal of biological and chemical oxygen demand (COD) at the completion of the batch rims was 96% and 78.6% respectively.

The new bathymetry data show that the shallower limits of the disposal site are positioned on the seaward edge of a gently dipping (3 degree ) mid-slope shoulder, between 1200 and 2100 m water depth. The slope below the disposal site is relatively steep (6.5 degree ) and is cut by submarine canyons which lead into the adjacent East Tasman Saddle. The SeaBeam bathymetry data show a small submarine canyon traversing the slope in 2400 m water depth directly downslope from the disposal site, with local slopes of up to 22 degree . The canyon feeds into a perched basin at 2450 m, which could be acting as a local sediment trap. Short (3000 m via turbidity flows sometime during the past 24 years. Current meter data collected from 30 m above the sea floor over one year at the disposal site show that bottom currents attain speeds of up to 0.46 m/s. The current events are attributed to eddies shed by the East Australia Current. The measured bottom currents are capable of transporting fine-grained hemipelagic muds and could provide a trigger mechanism for turbidity flows.

Sublittoral thalli collected around Helgoland, North Sea, Germany, from 6 m below the mean low water of spring tides contained less than 0.1 mg times g super(-1) dry weight (DW) total MAAs, whereas eulittoral samples contained over 1 mg times g super(-1) DW. Transplantation to shallow water led to the immediate synthesis of three MAAs in the following temporal order: shinorine ( lambda sub(max) 334 nm), asterina ( lambda sub(max) 330 nm), and palythine ( lambda sub(max) 320 nm), with the shinorine content peaking and then declining after 2 days (exposure to 100 mol photons times m super(-2)).

In this study, digestion of bacterial DNA with the restriction endonuclease NotI and PFGE were evaluated for the typing of isolates of Shigella dysenteriae type 1, an important cause of epidemic dysentery. There were 27 isolates from four outbreaks of dysentery, and 44 isolates from endemic dysentery cases and a laboratory culture collection. The epidemic isolates yielded two types each with two subtypes, whereas the endemic isolates and culture collection yielded eight types with numerous subtypes. These findings suggest that S. dysenteriae 1 can be typed by PFGE.

Daphnids were exposed to a range of DTPA concentrations at one, two and four times normal Fe, Zn and Mn concentrations, and one, two and three times the normal Cu concentration, in a series of four, three-brood reproductive experiments. Increasing the Fe concentration to 1280 mu g/l had no effect on the reproductive impairment after three broods of offspring. However, fourth brood was also monitored in the experiment, and some recovery in reproduction was observed at both 5 and 10 mg/l DTPA and 1280 mu g/l Fe. Speciation modelling indicated this was possibly due to an increase in the amount of available Fe, as Fe(OH) sub(2.7)Cl sub(0.3). Increasing the Cu concentration to 75 mu g/l (nominal) had no effect on the DTPA-induced reproductive impairment. Speciation modelling indicated that even at 75 mu g/l Cu, all Cu was bound to DTPA. Increasing the Zn concentration to 100 mu g/l (nominal) resulted in a 50-60% recovery in daphnid reproduction at 10 mg/l DTPA. However, speciation modelling indicated that, at 100 mu g/l Zn, all Zn was still bound to DTPA. Increasing the Mn concentration to 847 mu g/l resulted in a 60-70% recovery in daphnid reproduction at 10 mg/l DTPA, with speciation modelling indicating that the partial reproductive recovery was associated with an increase in available Mn, in the form of Mn-EDTA. The results of this study suggest that the DTPA-induced reproductive impairment observed in D. carinata is due to a large extent to the chelation of Mn and possibly Zn, while the chelation of Fe may also be of importance. The lowest-observed-effect concentration and no-observed-effect concentration of DTPA were 5 and 1 mg/l, respectively, based on reproduction.

(Compositae) is an extremely diverse genus of thistles, which includes several species that have become serious pasture weeds in several regions of the world. We present a comparison of the genetic diversity in invasive forms of Onopordum from Australia with several known native European species. A total of 108 polymorphic genetic markers was generated using amplified fragment length polymorphism (AFLP) fingerprinting. Non-metric multidimensional scaling (NMDS) revealed that Australia contained O. acanthium, O. illyricum and a full range of genetic intermediates between these species. Intermediates largely comprised segregating fragments diagnostic for European O. acanthium and O. illyricum with a low frequency of fragments that were diagnostic for other species never recorded in Australia. The current genetic patterns in Australia may be best explained by a combination of processes, both in the native and in the alien range. These include multiple introductions of seed, including hybrid material, and the continuous dispersal in Australia, leading to an increase in the contact among hybridizing taxa. Such processes appear to have produced more widespread hybridization and introgression in Australian Onopordum than is found in Europe.

Recent advances have resulted in several approaches to dealing with uncertainty in data used to classify species. These methods demand an unambiguous and transparent logical structure for the criteria. We suggest some changes to the ways in which the criteria are represented that correct an unnecessary inconsistency and which may serve to avoid important errors when uncertainty in the data is considered explicitly.

The distribution of essential metals was also examined. Results showed that food restriction and the accompanying weight loss resulted in increased blood, liver, and kidney Pb concentrations, along with higher hematocrits and reduced bone density. Swimming, which was used as the exercise, did not influence blood and organ Pb and essential element concentrations, but swimming did prevent a decrease in femur bone density. Organ iron concentrations increased during weight loss for all organs except brain, even through daily Fe intake was reduced during food restriction. Organ concentrations of calcium, copper, magnesium, and zinc, however, did not increase with weight loss, with limited exceptions, and the total content of these metals was decreased in several organs.

These zones are promulgated on acute exposure guideline levels. The extensive information available on ammonia is summarized, and its toxic potency is evaluated. Data are presented on the odor and odor threshold, vapor density, acute toxic inhalation effects as determined from animal and human studies, the relationship between concentration and exposure duration in producing toxic effect, the adoption of acceptable risk criteria, fatal exposure concentration, and irreversible injury concentration.

All workers for whom data were adequately complete were included in the study. Results showed that lifetime cumulative dose was associated positively with all cancer mortality under 5-, 10-, and 20-yr lag assumptions, but radiationcancer associations were of larger magnitude and better fit when radiation doses received after age 45 were examined than when associations with lifetime cumulative dose were examined. All-cause mortality was also associated positively with cumulative radiation dose received after 45 yr of age, but the association was not as strong as that for cancer. The best-fitting regression models were a 5-yr-lag assumption for lung-cancer mortality and a 20-yr-lag assumption for other cancers.

Some European countries, however, have banned chrysotile, and an European Union-wide ban is under consideration currently. The substitution of chrysotile in specific applications is discussed, especially p-aramid, polyvinyl alcohol, and cellulose in asbestos-cement products, friction materials, gaskets and sealing materials, composites, and heat-resistant textiles. The hazardous properties of chrysotile are elucidated, along with those of the substitute fibers, to show that the substitute fibers can be designed or selected to have particular characteristics, such that the risk of lung cancer and asbestosis can be reduced.

The subjects were divided into four groups according to the concentration of As in home drinking water, which ranged 8620 mu g/l. Each subject kept a 6-d diet diary. Results showed that the within-day variation in total As/mg creatinine concentration in urine was relatively small for members of the population and appeared to be independent of exposure as measured by As concentration in drinking water. Over any 5-d period, however, either the concentration of inorganic As in drinking water or the estimated As intake was a good predictor of total As/mg creatinine excretion. Age had a small effect on this relation, but gender did not.

The subjects were employed in an electronics-dismantling plant, as clerks working full-time at computer screens, and as control hospital cleaners. Results showed the presence of five congeners in all blood samples, but concentrations were higher in subjects from the dismantling plant. The major congener found in these subjects was 2,2',3,4,4',5',6-tetrabrominated diphenyl ether, at concentrations that were approximately 70 times higher than those found in the control group. The total median polybrominated diphenyl ether concentrations in blood of subjects from the dismantling plant, of computer clerks, and of the controls were 37.0, 7.3, and 5.4 pmol/g, respectively.

Meteorological and pollutant variables were considered by regressing them against optimal generalized additive model terms. Of the pollutant measures, PM sub(2.5) and nitrate had the highest partial correlations with mortality, but there were also reasonably high correlations with PM sub(10) and sulfate. These associations remained when the Bay Area met national air-pollution standards for every criteria pollutant.

This technique was used to reassess Schwartz and Dockery's analysis of the association of total suspended particulates (TSPs) with daily mortality from nonexternal causes among residents of Philadelphia, PA, from 1973 to 1980. The design utilized conditional logic regression models to analyze the exposure odds for the case period as compared with the control period. The results show that the previous results, which indicated an association of TSP concentration with increases in daily mortality, were not sensitive to a change in modeling techniques.

Forced vital capacity and forced expiratory volume in 1 s were used as the health endpoints. The study was conducted over a 2-yr period on 1001 children aged 9 yr at the beginning of the study. Results showed that the adjusted mean lung-function growth rate over the 2-yr follow-up period was lower significantly among boys and girls living in the more polluted area of the city, and this was observed especially clearly in boys. However, the level of pollutants within the study areas was relatively low, even in the more-polluted city center.

Adults lay after rain early in the wet season, mainly between October/November and January. On cracking clay soils, a fall of > 40 mm is required to allow oviposition, but to ensure survival of the resulting offspring, there must be follow-up rain of > 40 mm at the oviposition site within 6 weeks. Populations increase during years when more than 50% of the arid zone and Gulf receive both initial and two or more follow-up rains at intervals of less than or equal to 6 weeks. During the 1970s and 1990s, there were two periods of 3-5 years of such increase, and a large number of swarms resulted.

Aegilops tauschii), the D-genome progenitor of wheat. The library was made in a binary vector that had previously been shown to stably maintain large inserts of foreign DNA in Escherichia coli. The use of root nuclei reduced considerably the proportion of the library containing clones derived from chloroplast DNA. Several experimental parameters were investigated and optimised, leading to a high cloning efficiency. Only three ligations were needed to construct the library which was estimated to be equivalent to 3.7 haploid genomes. The accuracy of this estimation was demonstrated by screening this library with three well-defined probes. One probe containing a glutenin gene sequence identified 5 clones covering at least 230 kb of the Glu-D1 locus and contained the two tightly linked high-molecular-weight glutenin genes Glu-D1x and -D1y. Each of the other two single-copy probes derived from the Cre3 cereal cyst nematode resistance gene locus hybridised with 4 clones containing gene sequences encoding nucleotide binding sites and a leucine-rich region. This is the first representative large-insert DNA library for wheat, and the results indicated that large molecules of wheat DNA can be efficiently cloned, stably maintained and manipulated in a bacterial system.

AN - 62250387; ED463912 AB - A House of Representatives committee received testimony on programs for migrant children and for neglected and delinquent youth in the context of reauthorization of the Elementary and Secondary Education Act, Title I, Parts C and D, respectively. The director of the U.S. Office of Migrant Education explained changes in the reauthorization, including changes in funding formulas for state migrant programs, provisions covering interstate transfer of student records, and incentives for state consortia. A college student spoke of his experiences with the Migrant Education Program and related programs. Representatives of state programs and national migrant organizations discussed a home-based family literacy program in Pennsylvania; changes to federal legislation; Kentucky efforts to hold delinquent students in state programs to high standards and provide transition services after their release; and migrant education issues related to parent participation, data collection, records transfer, language of instruction, and interstate coordination. Appendices contain written statements, including a report by the Office of Migrant Education on what the Migrant Education Program does, its current status, recent innovations such as technology use, and proposed reauthorization changes; "A Comprehensive Plan for the Education of America's Migrant Children," prepared by three national migrant organizations; and "The Value of Migrant Education" (fact sheets and recommendations), by the Interstate Migrant Education Council.

We previously suggested that the immunogenicity of autologous tumor vaccines in humans may be augmented by engineering vaccinating tumor cell membranes to express alpha -galactosyl ( alpha -gal) epitopes (i.e., Gal alpha 1,3Gal beta 1,4GlcNAc-R). Subsequent in situ binding of natural anti-Gal IgG molecules to these epitopes would result in the formation of immune complexes that target tumor vaccines for uptake by APCs, via the interaction of the Fc portion of anti-Gal with Fc gamma receptors on APCs. This hypothesis was tested in a unique experimental animal model of knockout mice for alpha 1,3galactosyltransferase ( alpha 1,3GT) and the mouse melanoma B16-BL6 (referred to here as BL6). Like humans, these mice lack alpha -gal epitopes and produce anti-Gal. BL6 melanoma cells are highly tumorigenic, and like human tumor cells, they lack alpha -gal epitopes. Expression of alpha -gal epitopes on these melanoma cells was achieved by stable transfection with alpha 1,3GT cDNA. The transfected melanoma cells (termed BL6 sub( alpha GT)) express similar to 2 x 10 super(6) alpha -gal epitopes per cell and readily form immune complexes with anti-Gal. Vaccination of the mice with 2 x 10 super(6) irradiated melanoma cells that express alpha -gal epitopes, followed by challenge with 0.5 x 10 super(6) live parental melanoma cells, resulted in protection for at least 2 months (i.e., no tumor growth) in one-third of the mice, whereas all mice immunized with irradiated parental melanoma cells developed tumors 21-26 days post-challenge. The proportion of protected mice doubled when the mice were immunized twice with irradiated melanoma cells expressing alpha -gal epitopes and challenged with 0.2 x 10 super(6) live BL6 cells. Histological studies on the developing tumors in challenged mice that were immunized with melanoma cells expressing alpha -gal epitopes demonstrated extensive infiltration of T lymphocytes and macrophages, whereas no mononuclear cell infiltrates were observed in tumors of mice immunized with parental tumor cells. Overall, these studies imply that immunization of alpha 1,3GT knockout mice with BL6 melanoma cells that express alpha -gal epitopes elicits, in a proportion of the population, protective immune response against the same tumor lacking such epitopes. These studies further suggest that similar immunization of cancer patients with autologous tumor vaccines that are engineered to express alpha -gal epitopes may increase the immune response to autologous tumor-associated antigens and, thus, may elicit immune-mediated destruction of metastatic cells expressing these antigens.

AN - 62408577; ED433022 AB - The National Library Service (NLS) is developing a digital talking book and Braille book system for use by the blind and physically handicapped community. The following elements drive the design of the program: NLS offers a free library service; NLS is consumer-driven; NLS pays no royalties to copyright holders; the program is accessible to a wide variety of users; and the program's primary focus is the recreational and informational reading needs of patrons. Three assumptions have been made in planning for the next-generation talking book system: the system will be digitally based; the current cassette system will be in use for another seven to ten years; and a standard or slightly modified version of a widely-used consumer product/technology will be used to gain cost benefits of mass production. A National Information Standards Organization effort is underway to develop a standard to ensure compatibility of digital books, magazines, and playback equipment across national and agency boundaries. At the same time, four immediate tasks of the inhouse NLS group are: simulate a digital talking book using a personal computer; develop a computer-based life cycle cost analysis tool for the NLS system and candidate digital system; design and build a prototype digital collection accessing and archiving system; and design or select digital mastering and playback systems.

AN - 70815123; 10512203 AB - The gene trap technique is a powerful approach for characterizing and mutating genes involved in mouse development. However, one shortcoming of gene trapping is the relative inability to induce subtle mutations. This problem can be overcome by introducing a knock-in system into the gene trap strategy. Here, we have constructed a new gene trap vector, pU-Hachi, employing the Cre-mutated lox system (Araki et al., 1997), in which a pair of mutant lox, lox71 and lox66, was used to promote targeted integrative reaction by Cre recombinase. The pU-Hachi carries splicing acceptor (SA)-lox71-internal ribosomal entry site (IRES)-beta-geo-pA-loxP-pA-pUC. By using this vector, we can carry out random insertional mutagenesis as the first step, and then we can replace the beta-geo gene with any gene of interest through Cre-mediated integration. We have isolated 109 trap clones electroporated with pU-Hachi, and analyzed their integration patterns by Southern blotting to select those carrying a single copy of the trap vector. By use of some of these clones, we have succeeded in exchanging the reporter gene at high efficiency, ranging between 20-80%. This integration system is also quite useful for plasmid rescue to recover flanking genomic sequences, because a plasmid vector sequence can be introduced even when the pUC sequence of the trap vector is lost through integration into the genome. Thus, this method, termed exchangeable gene trapping, has many advantages as the trapped clones can be utilized to express genes with any type of mutation.

AN - 69867650; 10390501 AB - A bacterial plasmid was constructed on which the regulatory region of the umuC gene of Escherichia coli was fused to the coding sequence of the green fluorescent protein gene (gfp) from the jellyfish Aequorea victoria. Escherichia coli AB1157 strains carrying the plasmid emitted fluorescence in the presence of mutagens that induce the SOS DNA repair system. Data on tests with nitrosoguanidine, methylmethane sulphonate and UV radiation (254 nm) are presented. Although fluorescent detection using this system was not as rapid or sensitive as a similar luminescent equivalent (umuC-luxAB), the gfp reporter system was more robust. Escherichia coli umu gene induction was also analysed in Salmonella typhimurium TA1537 cells following plasmid transfer and exposure to the same range of mutagens. There was no significant difference in sensitivity between the two species.

United States Senate, One Hundred Sixth Congress, First Session. AN - 62313182; ED451011 AB - A Senate committee hearing received testimony on the creation of an American Indian Education Foundation. The foundation will be a charitable, nonprofit corporation authorized to accept and administer private gifts in support of the Bureau of Indian Affairs' (BIA) Office of Education and to conduct activities that further educational opportunities for American Indians and Alaska Natives in BIA schools. The foundation is modeled on the federally-chartered National Park Foundation and National Fish and Wildlife Foundation, and would provide a formal mechanism to channel private contributions to BIA schools. U.S. Congressmen and representatives of the BIA, tribal colleges, and various Indian education associations offered testimony and written statements concerning the deplorable condition of many Native American schools, the huge backlog of unfunded school construction needs in Indian country, the lack of funding for new technologies in schools and related teacher training, the involvement of tribal colleges in K-12 systemic change, and the structure of the proposed foundation. The appendix includes "Tribal Colleges: An Introduction," prepared by the American Indian Higher Education Consortium; specific recommendations about the purposes, structure, and operation of the foundation; and a detailed report on unfunded construction backlog items, by category and individual BIA school.

DC Tron suppressed development of powdery mildew but was not as effective as the conventional fungicide Topas. Of the oil treatments the 1% rate applied in spray volumes of 1000 L/ha was the most efficient. Poor control was achieved with oil rates less than 1% as well as spray volumes less than 1000 L/ha whereas phytotoxicity developed in many cases at concentrations greater than 1% or spray volumes higher than 1000 L/ha. In all oil treatments, powdery mildew developed less in leaves than on bunches. This difference was attributed to poor spray coverage on bunches compared to leaves.

Benyahia laboratory boat (ISMAL). Among these, 8 surface sea water samples (2m depth) were collected at a distance of about 4-5 miles from the shore, and the 5 others on a transection reaching a depth of 500 m. The remaining 5 samples were collected at different depths of the water column, ranging from 30 to 350 m. For the surface seawater, the sampling was performed using a pump system, however, for the depth seawater, a 501 PYC water-bottle sampler was used. The choice of the sampling depths, was based upon measurement of vertical profiles of temperature, salinity and pH, using a multiparameter probe. The collected samples were analysed to determine the super(137)Cs concentrations, using the AMP technique [1,2], and the chemical yield was calculated using the injected super(134)Cs isotope tracer activity. After chemical pretreatment, the AMP precipitates obtained were transfered to an appropriate plastic container, and oven-dried at 80 degree C for (24-48) h, in order to be counted. The dried precipitates were analysed by direct counting gamma spectrometry, using a high purity Germanium detector of relative efficiency of 20.6% and resolution (FWHM) of 1.8 keV at 1332 keV gamma-energy of60Co. For the determination of detection efficiency, two standard samples were prepared in the geometries of analysis, using caesium isotope tracers ( similar to 13Bq). JF - Marine Pollution.

The aim of this study is to detect any radioactive contamination, its origin and also to determine the uptake of radioactivity by marine surface sediments. Using a combination of direct gamma spectrometry, radiochemical separations, alpha-spectrometry and beta-counting, activity levels of the most significant naturally-occurring ( super(210)Po, super(226)Ra, etc.) artificial radioisotopes ( super(137)Cs, super(90)Sr and Pu isotopes) were determined III the samples. The gamma-emitting radionuclides were determined using GeLi detectors and two different geometries, namely, 500 cm super(3) Marinelli and 250 cm super(3) plastic cylindrical form beakers. For the alpha and beta emitters, after dissolution of the samples, radiochemical separations were undergone. The source of plutonium isotopes was prepared by coprecipitation method on a 0.1 mu m pore size membrane filter [1]. Regarding the super(90)Sr, the chemical recovery was determined by gravimetry and the final source was measured by liquid-scintillation-counting (LSC) [2]. JF - Marine Pollution.

AN - 1859309331; 10407444 AB - Potassium uptake is vital for plant growth but in saline soils sodium competes with potassium for uptake across the plasma membrane of plant cells. This can result in high Na+:K+ ratios that reduce plant growth and eventually become toxic. Our understanding of the molecular basis underlying the interaction between essential potassium and toxic sodium was limited until the recent cloning and electrophysiological characterization of several genes encoding different types of molecules that are involved in K+ and Na+ transport. These molecules, and their regulation, are important in determining the K+:Na+ homeostasis of plants in saline soils, although it is not yet known which is most critical in determining the K+:Na+ ratios in whole plants.

No eggs hatched at 12 degree C or 5ppt. Temperature was the dominant factor, with the optimum being 15 degree C. Higher temperatures resulted in lower hatch rates of smaller larvae with high deformity rates. Eggs incubated at lower salinities produced heavier larvae. The optimum temperature for larval rearing, as determined by growth and survival, was 21 degree C. Suggested protocols for egg incubation and larval rearing are given, in order to minimise confounding effects from deleterious husbandry practices when using this species in toxicological studies.

The literature asserts that interaction is the key to this process, but how interaction is translated into practice is less clear. In North Queensland, Australia, the Trinity Inlet Management Program has been designed to integrate the management of a marine estuary. An analysis of the approach offers lessons for practice by demonstrating how mechanisms for information exchange and joint decision making have increased coordination, and by demonstrating the potential difficulties of implementing IEM.

In this study we test whether pLy carrying covalently attached peptides comprising the T-ag NLS (the pLyP101 derivative) can enhance transferrin-pLy-mediated transfection ("transferrinfection"). Unlike pLy itself or a pLy derivative (pLyP101T) carrying cross-linked T-ag NLS mutant peptides, pLyP101 significantly enhanced transferrinfection of a beta -galactosidase-expressing reporter plasmid. The basis of this was shown to be the ability of the pLyP101-plasmid DNA complex to be recognized with high affinity by the NLS-binding importin subunits, in contrast to pLyP101T- and pLy-plasmid complexes. Confocal laser scanning microscopy was used to determine the nuclear import kinetics of fluorescently labeled pLyP101 and pLyP101T in the presence of complexed plasmid, indicating that pLyP101 and not pLyP101T complexes accumulated rapidly in the nucleus. We conclude that pLy itself does not function as an NLS and that the addition of exogenous NLSs conferring interaction with the cellular nuclear import machinery can increase transferrinfection by enhancing the nuclear targeting of pLy-DNA complexes.

The effects of these substances on fusidic acid resistance levels occurred in a strain-dependent manner. The weak acid acetate, and acetaminophen did not alter fusidic acid resistance levels, while the addition of saligenin, the alcohol of salicylate, reduced gradient plate MICs for all strains studied. These findings indicate that a benzoic acid structure is required for the induction of increased intrinsic fusidic acid resistance levels. When 2 mM salicylate was added to media used in population analyses, the number of cells able to survive on high concentrations of fusidic acid increased. This increase in cell survival was observed in two unrelated fusidic acid-resistant strains, with chromosomal (WBG8287) or plasmid (WBG1576) mediated resistance determinants and two unrelated susceptible strains. The salicylate-induced increase in fusidic acid resistance was phenotypic at low fusidic acid concentrations (relative to resistance phenotype) for WBG8287 and a fusidic acid-susceptible strain. On media containing salicylate and high fusidic acid concentrations, the mutation frequency to higher fusidic acid resistance levels was greater for WBG8287, compared with unsupplemented fusidic acid-containing media. These experiments provide evidence for a novel salicylate inducible fusidic acid resistance mechanism in S. aureus.

Using data from the literature for 184 sites around the world, I found that nature reserves had one-half of the exotic fraction of sites outside reserves, and island sites had nearly three times the exotic fraction of mainland sites. However, the exotic fraction and the number of exotics were also dependent on site area, and this had to be taken into account to make valid comparisons between sites. The number of native species was used as a surrogate for site area and habitat diversity. Nearly 70% of the variation in the number of exotic species was accounted for by a multiple regression containing the following predictors: the number of native species, whether the site was an island or on the mainland, and whether or not it was a nature reserve. After controlling for scale, there were significant differences among biomes, but not continents, in their level of invasion. Multiple biome regions and temperate agricultural or urban sites were among the most invaded biomes, and deserts and savannas were among the least. However, there was considerable within-group variation in the mean degree of invasion. Scale-controlled analysis also showed that the New World is significantly more invaded than the Old World, but only when site native richness (probably a surrogate for habitat diversity) is factored out. Contrary to expectation, communities richer in native species had more, not fewer, exotics. For mainland sites, the degree of invasion increased with latitude, but there was no such relationship for islands. Although islands are more invaded than mainland sites, this is apparently not because of low native species richness, as the islands in this data set were no less rich in native species than were mainland sites of similar area. The number of exotic species in nature reserves increases with the number of visitors. However, it is difficult to draw conclusions about relative invasibility, invasion potential, or the roles of dispersal and disturbance from any of these results. Most of the observed patterns here and in the literature could potentially be explained by differences between regions in species properties, ecosystem properties, or propagule pressure.

In the 1996-1997 austral summer, 130 Antarctic and subantarctic fur seal pups (Arctocephalus gazella and A. tropicalis) were born at Macquarie Island. During that season one subadult male Hooker's sea lion (Phocarctos hookeri) is believed to have caused the mortality of up to 43% of the pup cohort. During the 1996-1997 austral summer breeding season at Macquarie Island, all fur seal pups were individually marked with paint within the first week of birth and later with external tags in both foreflippers. An estimate of pup mortality was calculated based on pup carcasses discovered in and around the colony and the number of pups found to have disappeared well before weaning. On 23 January 1997 a subadult male Hooker's sea lion with a distinctive scar on its back was observed thrashing a tagged fur seal pup from side to side in shallow water. The remains of the pup's carcass were retrieved prior to any scavenging, which allowed direct evidence of sea lion predation to be recorded. Prior to the appearance of the sea lion on 23 January 1997, pup mortality was similar to that in the previous two seasons (12%-14% by 23 January) and comparable to the level of pup mortality found in most other fur seal species. Between 23 January and 26 February 1997, cumulative pup mortality rose from 14% to 64%, much higher than for 1994-1995 or 1995-1996 at the same time of year. Although only two pups were seen killed, we believe there is strong circumstantial evidence that the sea lion was responsible for most of the remaining deaths (i.e., 54 pups).

AN - 17308696; 4572080 AB - The earplugs of several baleen whale stocks exhibit seasonal growth layers which have been shown for some species to indicate the total age of the animals. A transition from early, irregular layers, to later, more regular layers can be seen in these earplugs, and this is thought to indicate the age at maturity of the whale. The earplugs of Southern Hemisphere minke whales are relatively difficult to read, particularly for the age at transition, and it has been suggested that these readings reflect no more than random allocations by the reader, rather than any real effect. Plots of average transition phase against year of birth (cohort) show a decline in the average age at transition. However, certain factors can result in a downward bias in this trend, particularly when only a short time-series is available for analysis, as was the case when this trend was first estimated some 15 yr ago. Data collected over 25 yr are now available and are reanalyzed here. A plot of mean age at transition against year of sampling for animals of similar age shows a decline, as does the conventional plot against cohort, suggesting that the decline is real. A model that simulates random allocation of the transition phase by earplug readers yields predictions that show systematic deviations from the data.

Use of biological control agents, and specifically entomopathogenic micro-organisms, could be an alternative method to chemical control. From this perspective, we carried out a screening and an evaluation of local granuloviruses which are naturally present in Indonesian pest populations. The use of an enzyme-linked immuno-sorbent assay allowed us to isolate three granulovirus strains from P. operculella larvae collected from three different locations in Indonesia: Wonsosobo (Central Java), Lembang (West Java), and Berastagi (Northern Sumatra). Bioassays did not reveal significant differences in the biological properties (LC sub(50) and ST sub(50)) of these strains. The restriction pattern of the viral genome (Wonsosobo strain) presented only minor variations compared to other isolates collected in different regions of the world.

The 45 study subjects consisted of service-station attendants, street vendors, and office workers, which represented high, medium, and low exposure levels, respectively. Passive organic-vapor badges were used. The badge data showed that exposure levels of benzene, ethylbenzene, and m-, p, and o-xylenes were significantly higher for the service-station attendants than for street venders and office workers, but exposure levels for toluene were higher among office workers than among street vendors. The median blood benzene levels of the service-station attendants, street vendors, and office workers were 0.63, 0.30, and 0.17 mu g/l, respectively. Blood levels of ethylbenzene, xylenes, and methyl-tert-butyl ether were also highest among service-station attendants. Similar results were found for post-shift blood benzene levels and post-shift concentrations of other VOCs.

Mercury exposure was assessed by determining the Hg concentration in hair samples. Results showed that Hg exposures were lowest in a village located beyond the junction with the Amazon River, where only two of 105 children had a hair Hg concentration above 10 mu g/g, in contrast to 58 of 76, 65 of 71, and 80 of 87 children, respectively, who exceeded this limit in the other three villages. Maternal hair Hg concentrations were correlated highly with those of their children. Dietary habits were similar in the four villages, with most children eating fish at two meals each day. Tests of motor function, attention, and visuospatial performance indicated decrements associated with the hair Hg concentrations.

It has been widely held that nitrates in drinking water are a primary cause of the disease in infants. Over the past 20 yr, however, a more complex picture of infantile methemoglobinemia has emerged, suggesting that current limits on drinking-water NO sub(3) may be too strict. Indeed, a putative mechanism has been established whereby gastrointestinal inflammation leads to methemoglobinemia; nitric oxide is produced by several tissues in response to infection and inflammation. Various studies are cited in an assessment of the relationship of NO sub(3) in drinking water and incidences of infant methemoglobinemia. It is suggested that raising the drinking-water standard for NO sub(3) from the current 10 ppm to 15 or 20 ppm would not increase the health risk to infants and would reduce the need for expensive water treatment to comply with the current maximum contaminant level.

Reproductive toxicity was assessed in terms of daily sperm production, hyaluronidase activities, and histological changes in the testis. Both total and filtered diesel exhausts were used. The dosing experiments were conducted for three months beginning at birth. Results showed that, compared to controls, rats exposed to total diesel exhaust and filtered exhaust exhibited significantly higher serum levels of testosterone and estradiol. Follicle-stimulating hormone was decreased significantly in both exposed groups, while luteinizing hormone was decreased significantly in the total exhaust-exposed group. No physically visible differences were noted among groups, but sperm production was decreased significantly in both groups exposed to diesel exhaust. The morphological and immunohistochemical alterations are described.

Results showed that, after controlling for long-term time trend, seasonality, barometric pressure, and weather variables, daily mortality counts were associated positively with 5-d lagged moving-average concentrations of PM sub(10) in all three metropolitan areas studied. This estimated association was larger when mean data from multiple monitors were used, rather than only data from one monitor. The estimated association was strengthened when the data were screened to exclude episode days that obviously were dominated by windblown dust. The estimated percent changes in mortality associated with a 10- mu g/m super(3) increase in PM sub(10) concentration were 1.6, 0.8, and 1.0%, respectively, for the Ogden, Salt Lake City, and Provo/Orem areas.

Uranium mining operations are quite widespread in northern Saskatchewan. Concentrations of U, radium-226, lead-210, polonium-210, cesium-137, and potassium-40 were determined in lichens and caribou, and uptake in aborigines from the consumption of caribou was calculated. The only radionuclides found in caribou soft tissue were super(210)Po, super(137)Cs, and super(40)K. Food-chain transfer from lichen to caribou muscle, using concentration ratios, was determined to be 13, 67, 12, and 2226% for U, super(226)Ra, super(210)Pb, and super(210)Po, respectively. The annual effective dose from the consumption of 100 g/d of caribou meat was calculated at 0.85 mSv/yr, which was almost doubled with the additional consumption of one liver and 10 kidneys/yr.

Groundwater ingestion and dermal contact were evaluated as local priority pathways via field questionnaires. The data were used as input to a model of the relationship between risk and the pathway exposure factor. Results showed that the mean levels of the 24 target heavy metals did not exceed US maximum contaminant levels, and no target base/neutral/acid organic compounds were detected. gamma -Chlordane was the only chlorinated pesticide found, along with several PCB congeners. The main priority agents recorded were pathogens, which were not restricted to the wastewater-irrigation district. By the coliform criterion, a potential risk of gastrointestinal disease was identified, with total coliforms and Escherichia coli counts above the Mexican standard. By the NO sub(3) criterion, the infant and young children groups were at risk from methemoglobinemia at all sites and were not restricted to the wastewater-irrigation district.

The biosamples were collected from 995 study subjects between January 1995 and December 1997. All of the samples were self-collected, but some were provided in the laboratory and others were mailed into the laboratory. The samples were evaluated in terms of the effects of fresh-processed versus mailed biosampling, biosample purification, time from laboratory receipt to DNA extraction, and long-term storage. The results showed that fresh-processed buccal swabs provided a higher PCR success rate than mailed buccal swabs. However, purification of mailed biosamples appeared to improve PCR success. Storage for up to 12 months at 4 degree C did not appear to affect PCR success significantly.

Total RNA was isolated and subjected to reverse transcriptase polymerase chain reaction. Treatment of the cells with 53 mu M Cd for 4 h, followed by removal of the metal through a change in growth medium and subsequent monitoring of hsp 27, caused an increase in both hsp 27 mRNA and protein, as well as a shift in hsp 27 isoforms to a pattern of increased phosphorylation. Acute exposure to lethal concentrations of Cd did not immediately inactivate any of the cellular components necessary for transcription, translation, or phosphorylation of hsp 27 in the human proximal tubule cells. The results further showed that constitutive levels of hsp 27 protein were not maintained in human proximal tubule cells during chronic Cd exposure, which suggested that the cytoskeleton might be a site particularly susceptible to damage in Cd-induced nephropathy.

This construct is used to perform a detection assay of the estrogenic activity of a number of chemical compounds. The development of the assay is outlined, and results are presented in terms of the efficiency of transcriptional activation of a classical consensus ERE and that of the overlapping ERE unit. The results show that synergistic activation of transcription elicited by the overlapping ERE sequence is observed for both a natural hormone and for organochlorine chemicals with estrogenic activity. This allows the detection of smaller amounts of xenoestrogens than with a classical consensus ERE.

Levels of photosynthetically active radiation 3-5 times below surface irradiance caused krill to die within a week, while animals in the dark survived. Addition of ultraviolet-B typical of depths up to 15 m were found to significantly accelerate mortality and lead to a drop in activity in all experiments. A drop in activity in krill exposed to ultraviolet-A wavelengths was evident without an increase in mortality. The protein content of animals from various treatments was found not to vary.

Hearing before the Subcommittee on Criminal Justice, Drug Policy, and Human Resources of the Committee on Government Reform. House of Representatives, One Hundred Sixth Congress, First Session. AN - 62315712; ED451809 AB - This hearing was held to consider whether the student loan programs of the Department of Education place tax dollars at risk. In his opening remarks, Representative John L. Mica (Florida) pointed out that for nearly 10 years, the U.S. General Accounting Office has labeled these programs as a high risk for fraud, waste, abuse, and mismanagement. In 1998, Congress created the first Federal sector performance based organization (PBO) to bring about some reforms in student loan programs. One purpose of these hearings was to assess the PBO's progress to date. A recent report by the Inspector General's Office suggests that the Department of Education has incorrectly forgiven many loans to students who could well be paying them back, especially students who claimed to be dead when they were not. Although the default rate on student loans has dropped slightly, there were still about $20 million in default at the time of the hearing. Statements about the student loan program and the need for reform were given by Representatives Elijah E. Cummings (Maryland), Benjamin Gilman (New York), Dennis Kucinich (Ohio), and Patsy T. Mink (Hawaii). Also presenting testimony were: (1) John Berthoud, National Taxpayers Union; (2) Thomas A. Butts, National Direct Student Loan Coalition; (3) Fred J. Galloway, former loan program evaluator; (4) Steven A. McNamara, Assistant Inspector General for Audit (Department of Education); (5) Marshall S. Smith, Acting Deputy Secretary, Department of Education; and (6) Greg Woods, Chief Operating Office, Office of Student Financial Assistance Programs, Department of Education. The prepared statements of these witnesses and letters and statements submitted for the record are included. Among these, the report of the Office of the Inspector General, U.S. Department of Education is of particular interest.

The entire sequence of the starch synthase-I cDNA (wSSI-cDNA) is 2591bp, and it encodes a polypeptide of 647 amino-acid residues that shows 81% and 61% identity to the amino-acid sequences of SSI-type starch synthases from rice and potato, respectively. In addition, the putative N-terminal amino-acid sequence of the encoded protein is identical to that determined for the N-terminal region of the 75-kDa starch synthase present in the starch granule of hexaploid wheat. Two prominent starch synthase activities were demonstrated to be present in the soluble fraction of wheat endosperm by activity staining of the non-denaturing PAGE gels. The most anodal band (wheat SSI) shows the highest staining intensity and results from the activity of a 75-kDa protein. The wheat SSI mRNA is expressed in the endosperm during the early to mid stages of wheat grain development but was not detected by Northern blotting in other tissues from the wheat plant. The gene encoding the wheat SSI (SsI-D1) consists of 15 exons and 14 introns, similar to the structure of the rice starch synthase-I gene. While the exons of wheat and rice are virtually identical in length, the wheat SsI-D1 gene has longer sequences in introns 1, 2, 4 and 10, and shorter sequences in introns 6, 11 and 14, than the corresponding rice gene.

Forest soils are notoriously variable and small changes in soil properties can have a large impact on tree productivity. Likewise, within-site variation in microclimate is known to influence growth. Within a particular climatic envelope, this variation is controlled to a large extent by topography. In this study, a range of terrain-derived attributes and indices was calculated for each of 40 growth plots from a digital elevation model (DEM) in an attempt to quantify the effects of spatial heterogeneity and establish whether they improved the interpretation of data from a field experiment. In addition, selected soil profile measurements were analyzed for their impact on tree growth and correlated with calculated terrain attributes. The presence of gleying (evidence of waterlogging) in the profile accounted for a significant proportion of the residual variation in growth response after treatment effects were removed. A combination of predicted erosion index (ei), relative available soil water (raswc), dynamic wetness index (dynwet) and tangential curvature (tancurve) contributed to significant improvements in model predictions of growth. A physiologically based model of tree growth (P RO M OD ) was applied to the site to model the effect of these variables on tree growth. We found that by using a terrain-derived waterlogging or gleying variable as input, P RO M OD could successfully account for variation in tree growth due to waterlogging (gleying) and some additional between-plot variation in growth due to soil depth.

AN - 17405191; 4634151 AB - The fouling organisms on Port Bonython pier, South Australia, had previously been monitored for 6.5 yr after initial immersion of piles using photographs of fixed positions and direct observation by divers. Up to that date it appeared that predictions based on experiments at more sheltered sites had not been fulfilled. In particular, the assemblage had not become dominated by modular organisms. The rate of change seemed to be slowing after 6.5 yr but this could not be tested. The assemblage on the piles was re-examined in December 1995, after a further 7 yr. Faunal composition differed at sites along the pier throughout the study, and still did so after 13.5 yr, but the composition at all sites tended to change in a similar way through time; positions differed in a consistent way at 6.5 and 13.5 yr, probably reflecting consistent environmental differences between sites along the pier. Abundances of key taxa fluctuated markedly from site to site at any one time, and through time. As originally predicted, after 13.5 yr much of the pile surface area had become covered by encrusting or mound-forming modular animals (54%), especially sponges, and by foliose red algae (25%); unitary organisms such as bivalves and solitary ascidians had become greatly reduced in abundance. It is now clear that the overall composition of the assemblage had not converged to a `stable' condition by 6.5 yr; more sampling dates would be needed to determine whether it had done so by 13.5 yr.

A precursor pool for apoe secretion. AN - 69807410; 10357834 AB - There appear to be multiple post-translational sites for regulation of macrophage apolipoprotein (apo)E secretion, including the presence of a distinct cell surface pool of apoE. Cell surface proteoglycans have been shown to be involved in forming this pool. The current studies were designed to investigate the role of an additional cell surface site, i.e., the low density lipoprotein (LDL) receptor. Antiserum to the LDL receptor displaced apoE from the macrophage cell surface and into the medium during a 4 degrees C incubation from apoE-expressing J774 cells, from proteoglycan-depleted apoE-expressing J774 cells, and from human monocyte-derived macrophages. Similar results were obtained when purified monoclonal antibody to the LDL receptor was added to human monocyte-derived macrophages. J774 cells transfected to express an LDL receptor binding-defective mutant of apoE did not show a similar response to addition of LDL receptor antibody. Studies were conducted in which cells were pulse labeled for 30 min, followed by various periods of chase at 4 degrees C or 37 degrees C in the presence or absence of LDL receptor antibody. The results of these studies indicated that nascent macrophage-derived apoE binds to the LDL receptor, and that this apoE served as a precursor pool for apoE released into the medium. These studies establish a role for the LDL receptor in forming the cell surface pool of apoE and, along with data regarding the importance of proteoglycans, indicate that cell surface binding sites for nascent macrophage-derived apoE are heterogeneous. The heterogeneity of such sites could have implication for the size and turnover of this cell surface pool.

Two National Center for Education Statistics data sets provided the data for the analysis: National Household Education Survey, which provides information describing all educational activities of adults, and National Postsecondary Student Aid Survey, which provides detailed information about how employers help students pay for postsecondary education. Some of the findings were the following: (1) 13 percent of adults participated in credential programs in 1995, compared with about 20 percent who participated in work-related or other structured programs; (2) 72 percent of adults employed as engineers, surveyors, or architects who enrolled in credential programs received financial assistance from their employers, compared with 50 percent of employees who were executives, administrators, and managers, 10 percent of employees who were marketing and sales workers, and 4 percent who were low-skilled manual laborers; (3) adults who worked part time were less likely to receive employer financial aid if they enrolled in credential programs (7 percent) than those who worked full time (37 percent); (4) 6 percent of all undergraduates received financial aid from their employers, averaging $932, and 13 percent of graduate and first-professional students received employer assistance averaging $2,451; and (5) male graduate students received approximately one-third more employer financial aid than female students.

It summarizes the deliberations of 43 participants involved in a 2-day forum on educational leadership. Participants included superintendents, principals, and teachers from urban, suburban, and rural school districts, as well as prominent researchers in education leadership, state policymakers, education consultants, professional development specialists, education officials, and others. The forum used a seminar approach in which leading practitioners and researchers made brief presentations that included information about successful schools and districts; the presentations were followed by discussions that focused on select questions, such as What is the definition of an effective leader for today's schools? and Which practices do successful leaders use to improve teaching and learning? The forum found that educational leaders' jobs are changing dramatically and that today's schools demand new kinds of skills and knowledge from leaders, including skills that many current educators have not mastered. Successful districts around the U.S. are testing new models of leadership that bring together superintendents and others to do cross-role work on improving instruction. Some newer, effective models for professional development give people practical opportunities to build instructional leadership and other important skills in real school contexts. Contains a list of participants.

National Study of Charter School. Third-Year Report. AN - 62485745; ED430323 AB - This report provides descriptive information on charter schools that were in operation during the 1997-98 school year. The report is part of a 4-year research program that will document and analyze the charter-school movement. Data were gathered using phone surveys, repeated field visits to a sample of charter schools and their surrounding districts, student achievement tests administered at a sample of charter schools, the collection of existing student assessments for a sample of charter schools and for other public schools, and other methods. The report opens with an overview of the charter movement, paying particular attention to the differences across charter states in terms of the number of charter schools. The next section summarizes basic characteristics of charter schools compared to other public schools, and includes such data as school size, grade-level configuration, percentages of certificated teachers, and student-to-computer ratios. The third section compares student-demographic features of charter schools to that of other public schools. The last section reviews data on several issues that are central to understanding how charter schools may operate differently from other public schools. Data show that an additional 361 charter schools opened in 1998, raising the total number of charter schools to 1,050, operating in 27 states.

AN - 21260743; 11703771 AB - This study was conducted in a school center that had been the focus of intense public concern over 2 years because of suspected mold and health problems. Because several attempts to find solutions to the problem within the community were not satisfactory, outside specialists were needed for support in solving the problem. The study group consisted of experts in civil engineering, indoor mycology, and epidemiology. The studies were conducted in close cooperation with the city administration. Structures at risk were opened, moisture and temperature were measured, and the causes of damage were analyzed. Microbial samples were taken from the air, surfaces, and materials. Health questionnaires were sent to the schoolchildren and personnel. Information on the measurements and their results was released regularly to school employees, students and their parents, and to the media. Repairs were designed on the basis of this information. Moisture damage was caused mainly by difficult moisture conditions at the building site, poor ventilation, and water leaks. Fungal genera (concentrations &200 colony-forming units (cfu)/m(3), &3000 cfu/cm(2)) typical to buildings with mold problems (e.g., Aspergillus versicolor, Eurotium) were collected from the indoor air and surfaces of the school buildings. Where moisture-prone structures were identified and visible signs of damage or elevated moisture content were recorded, the numbers of microbes also were high; thus microbial results from material samples supported the conclusions made in the structural studies. Several irritative and recurrent symptoms were common among the upper secondary and high school students. The prevalence of asthma was high (13%) among the upper secondary school students. During the last 4 years, the incidence of asthma was 3-fold that of the previous 4-year period.

AN - 21251039; 11703767 AB - Evidence shows that fetuses and infants are more affected than adults by a variety of environmental toxicants because of differential exposure, physiologic immaturity, and a longer lifetime over which disease initiated in early life can develop. In this article we review data on the effects of in utero exposure to common environmental contaminants, including polycyclic aromatic hydrocarbons (PAH), particulate matter and environmental tobacco smoke (ETS). We then summarize results from our molecular epidemiologic study to assess risks from in utero exposures to ambient air pollution and ETS. This research study, conducted in Poland, used biomarkers to measure the internal and bioeffective dose of toxicants and individual susceptibility factors. The study included 160 mothers and 160 newborns. Ambient air pollution was significantly associated (p= 0.05) with the amount of PAH bound to DNA (PAH-DNA adducts) in both maternal and infant cord white blood cells (WBC). Newborns with elevated PAH-DNA adducts (greater than the median) had significantly decreased birth weight (p= 0.05), birth length (p= 0.02), and head circumference (p= 0.0005) compared to the newborns with lower adducts (n= 135). Maternal and infant cotinine levels were increased by active and passive cigarette smoke exposure of the mother (p= 0.01). An inverse correlation was seen between newborn plasma cotinine (nanograms per milliliter) and birth weight (p= 0.0001) and length (p= 0.003). Adducts were elevated in placental tissue and WBC of newborns who were heterozygous or homozygous for the cytochrome P4501A1 MspI restriction fragment length polymorphism (RFLP) compared to newborns without the RFLP. Levels of PAH-DNA and cotinine were higher in newborns than mothers. These results document that there is significant transplacental transfer of PAH and ETS constituents from mother to fetus; that PAH-DNA adduct levels in maternal and newborn WBC were increased with environmental exposure to PAH from ambient pollution; and that the fetus is more sensitive to genetic damage than the mother. The study also provided the first molecular evidence that transplacental PAH exposure to the fetus is compromising fetal development. If confirmed, these findings could have significant public health implications since a number of studies have found that reduction of head circumference at birth correlates with lower intelligence quotient as well as poorer cognitive functioning and school performance in childhood.

AN - 21250861; 11702206 AB - In studies on the relation between indoor mold exposure and symptoms/disease, the exposure should be described in terms of biomass and not viability. This paper reviews field studies in which (1--> 3)-ss-d-glucan was measured as a marker of biomass and was related to the extent of symptoms and measures of inflammation among exposed subjects. Increased levels of (1-->3)-ss-d-glucan were related to an increased extent of symptoms and markers of inflammation.

AN - 21250824; 11702205 AB - The prevalence and severity of asthma has increased in the last 20 years, and the greatest increase has been seen among children and young adults living in U.S. inner cities. The reasons for this increase are obviously complex, but include environmental exposures to allergens and pollutants, changing patterns of medication, and the psychosocial stresses of living in poor inner-city neighborhoods. This paper presents an overview of environmental, immunologic, and genetic factors associated with asthma morbidity and mortality. This overview can be used to provide a framework for designing an interdisciplinary research program to address the complexities of asthma etiology and exacerbation. The strongest epidemiologic association has been found between asthma morbidity and the exposure of immunologically sensitive asthmatic patients to airborne allergens. Our current understanding of the process of sensitization suggests that there is a strong genetic predisposition to form IgE to allergenic proteins on airborne particles. Much of this work has been conducted with animal models, but in a number of instances, specific confirmation has been reported in humans. Sensitized individuals respond to inhaled exposure with immediate mast-cell dependent inflammation that may be augmented by pollutant particles, especially diesel exhaust particles. Relatively little is known about the methods of assessing exposure to airborne pollutants, especially biologically active particulates. However, to examine the relationship of morbidity in genetically predisposed individuals, it will be important to determine the most relevant method of making this assessment.

AN - 21250567; 11702204 AB - This is a review of exposure conditions, clinical presentation, and morbidity of children and adults with indoor fungal exposure such as toxic Stachybotrys chartarum. Indoor exposure was characterized using different methods including microscopic, culture, cytotoxicity screening tests, and chemical analyses. Clinical case histories and physical and laboratory findings are presented of children (age & 18 years, n = 22; mean age 9 years; 60% females) and adults (age >18 years, n = 125; mean age 39 years, 67% females) who consulted an environmental health specialty clinic. In the pediatric patients' exposure history, widespread fungal contamination of water-damaged building materials with known toxic or allergic fungi was identified. Primarily disorders of the respiratory system, skin, mucous membranes, and central nervous system were reported. Some enumeration and functional laboratory abnormalities, mainly of the lymphatic blood cells, were observed, although no statistically significant differences were found. IgE or IgG fungi-specific antibodies, used as exposure markers, were positive in less than 25% of all tested cases. In an evaluation of a symptomatic girl 11 years of age (sentinel case investigation) living in an apartment with verified toxigenic fungi (i.e., S. chartarum), several health indicators showed improvement after exposure cessation.

A 39-year-old African American male with hypertension presented to Rush Presbyterian St. Luke's Medical Center with a 1-month history of progressive dyspnea on exertion, orthopnea, and dependent edema. He was taking Ma Huang (Herbalife) 1-3 tablets twice daily for 3 months along with other vitamin supplements, pravastatin, and furosemide. Physical examination revealed a male in mild respiratory distress. The lung fields had rales at both bases without audible wheezes. Internal jugular venous pulsations were 5 cm above the sternal notch. Medical therapy with intravenous furosemide and oral enalapril was initiated upon admission. Cardiac catheterization with coronary angiography revealed normal coronary arteries, a dilated left ventricle, moderate pulmonary hypertension, and a pulmonary capillary wedge pressure of 34 mm Hg. The patient had right ventricular biopsy performed demonstrating mild myocyte hypertrophy and an infiltrate consisting predominantly of lymphocytes with eosinophils present in significantly increased numbers. Treatment for myocarditis was initiated with azothioprine 200 mg daily and prednisone 60 mg per day with a tapering course over 6 months. Anticoagulation with warfarin and diuretics was initiated and angiotensin-converting enzyme inhibition was continued. Hydralazine was added later. One month into therapy, an echocardiogram demonstrated improved left ventricular function with only mild global hypokinesis. A repeat right ventricular biopsy 2 months after the first admission showed no evidence of myocarditis. At 6 months, left ventricular ejection fraction was normal (EFN 50%) and the patient asymptomatic. Ephedra (Ma Huang) is the suspected cause of hypersensitivity myocarditis in this patient due to the temporal course of disease and its propensity to induce vasculitis.

Anti BPDE Immunoglobulin G (IgG) were elicited in Swiss mice before subsequent carcinogen administration. The immunization schedule consisted of four weekly subcutaneous injections of both ( plus or minus )-anti BPDE-gelatin (BPDE-Gel) and DNA (BPDE-DNA) conjugate, followed by a final immunogen injection 14 days later. The immunization procedure resulted in the production of specific anti-BPDE antibodies in all treated animals. One week after the end of the immunization procedure, both groups of immunized and non immunized mice were treated with different doses of B[a]P (25-50-100-200 mg B[a]P/Kg body weight) by intraperitoneal injection. Seven days after treatment, the mice were sacrified. Adduct levels were detected by competitive ELISA by using optimal conditions established in our laboratory and highly specific and sensitive IgG anti BPDE-DNA induced in rabbit. The determination of DNA adducts in liver revealed significantly lower B[a]P adduct levels in liver of immunized mice with respect to non-immunized animals. This result confirms those obtained for 2-acetylaminofluorene (2-AAF) in a previous work: the specific humoral immunity elicited by repeated carcinogen exposure may be able to modulate the genotoxic effect induced by subsequent carcinogen administration.

The ability of different rhizobial isolates collected from any one site to establish effective nitrogen-fixing associations with host-plants from that site showed significant variation in 22 host Acacia species and nearly all of 67 populations. The average Acacia host-Rhizobium strain combination was only about 70% effective. Many combinations were far poorer; in a few cases the worst combination resulted in plants less than one-tenth the size of the best combinations. 2. The ability of rhizobial isolates to form effective symbiotic interactions showed marked host population and rhizobial-isolate effects in a study of eight, four and nine populations of A. dealbata, A. implexa and A. mearnsii. A more complete trial involved three populations of each of A. dealbata, A. implexa, A. irrorata, A. mearnsii and A. melanoxylon. These were inoculated with a range of rhizobial isolates previously shown to be highly, moderately or weakly successful in forming an effective association. Evidence of marked host population and rhizobial origin effects was found but there was very little evidence of isolate-host population interaction effects. 3. The general lack of host population-rhizobial origin interaction effects suggests that rhizobial strains selected as highly effective for an Acacia species growing in a particular population will generally perform well symbiotically with that species in other populations. This will make their practical application as inoculants in revegetation and forestry situations much easier. 4. Significant host-based variability in the ability to form effective symbiotic interactions was detected in comparisons of half-sib families of A. dealbata, A. mearnsii and A. melanoxylon. In the case of A. dealbata, the interaction between half-sib family lines and rhizobial isolates was complex, with `locally' derived isolates performing better than `foreign' ones. There were also significant interaction effects. In A. mearnsii, on the other hand, the only significant differences were detected between the response of different half-sib families to the same rhizobial isolate. The occurrence of host-based variability indicates that in Acacia breeding programmes attention should be given to the possibility of inadvertent selection affecting these relationships.

Our results indicate that no aspartate residue has a pK sub(a) greater than similar to 4.8 in any of the three complexes studied. The resonance of aspartate 26 in the dibydrofolate-enzyme complex has been assigned by site-directed mutagenesis; aspartate 26 is found to have a pK sub(a) value of less than 4 in this complex. Such a low pK sub(a) value makes it most unlikely that the ionization of this residue is responsible for the observed pH profile of hydride ion transfer [apparent pK sub(a) = 6.0; Andrews, J., Fierke, C. A., Birdsall, B., Ostler, G., Feeney, J., Roberts, G. C. K., and Benkovic, S. J. (1989) Biochemistry 28, 5743-5750]. Furthermore, the downfield chemical shift of the Asp 26 super(13)C gamma resonance in the dihydrofolate-enzyme complex provides experimental evidence that the pteridine ring of dihydrofolate is polarized when bound to the enzyme. We propose that this polarization of dihydrofolate acts as the driving force for protonation of the electron-rich O4 atom which occurs in the presence of NADPH. After this protonation of the substrate, a network of hydrogen bonds between O4, N5 and a bound water molecule facilitates transfer of the proton to N5 and transfer of a hydride ion from NADPH to the C6 atom to complete the reduction process.

Lucanids are saproxylic beetles, dependent on dead, moribund and decaying wood. Samples taken from old-growth forest and from a chronosequence of sites regenerating after logging, in each forest type, were used to compare the species richness and abundance of the lucanid assemblages. In both forest types, species richness and abundance was highest in the youngest regeneration sites (1-3 year), reflecting the species richness of the original and adjacent unlogged forest, lowest in the older (20-25 year) sites, and variable in the old-growth sites. TWINSPAN cluster analysis showed no clear distinction between regeneration and old-growth forest. The post-harvest slash and stump residue provided an important refugium and initial habitat, but our research indicates that some species may not maintain populations in the long term. Our results suggest that most species of lucanids will find a continuous supply of suitable habitat only in old-growth forests; and such species may become less common as clearfell harvesting leads to a replacement of heterogeneous old-growth forest with single-aged monospecific stands. Continuity of supply of wood in all decay stages, the maintenance of sufficient source areas, and biological connectivity between old-growth stands to enable dispersal, are all likely to be essential to maintain lucanid beetle community integrity. If similar principles apply to other saproxylic species of invertebrate, then clearfelling and slash-burning may cause a gradual extinction of an important element of the forest biota.

Using a wt-p53 recombinant adenovirus (Ad-p53), we demonstrated that exogenous wt-p53 expression was able to increase the sensitivity to BCNU in ADF cells. Interestingly, this effect was more evident when Ad-p53 infection was performed after BCNU treatment compared with the opposite sequence. To understand the biological basis of these different behaviors, we analyzed the cell cycle of the differently treated cells. We found that Ad-p53 infection induced a persistent accumulation of cells in the G0/G1 phase while, as expected, BCNU induced a block in the G2-M phase. Ad-p53 arrow right BCNU sequence did not significantly modify the cell cycle profile in respect of Ad-p53 infected cells. In contrast, BCNU arrow right Ad-p53 sequence provoked G2-M arrest similar to that observed after treatment with BCNU alone, but prevented the later recovery of the cells through the cell cycle, by driving the cells to apoptotic death. These results demonstrate that the administration sequence is important to increase drug sensitivity. To generalize the phenomenon observed on ADF line, the antiproliferative effect of the two different schedules was analyzed on other glioblastoma lines (A172, CRS-A2, U373MG) with different BCNU sensitivity and p53 status. The data obtained confirm that the wt-p53 gene transfer enhances BCNU sensitivity in glioblastoma cells depending on the administration sequence.

The dominant species in the urban plantation were Cryptomeria japonica and Chamaecyparis obtusa. A variety of eight patches of the canopy was produced by previous forest management practices. Progressive and retrogressive species dynamics within these eight patches are investigated in this paper. The study elucidates the deterministic role of patchiness in the nature of species colonization and the maintenance of species diversity in an urban forest. Altogether 139 native and/or naturalized species, including 23 shrub and 35 tree species, were recorded in the study area of 3.2 ha. The performance of species varied according to their successional attributes indicating a selective canopy influence. Twenty percent of the tree species were shade-intolerant pioneers (e.g. Cornus spp., Rhus javanica var. roxburghii) re-established under selective tree-felling. Thirty percent were shade-tolerant climax species (e.g. Neolitsea sericea, Persea thunhergii) dominant in remnant closed patches. The remaining 50% belonged to various seral types with aggressive deciduous species (e.g. Aphananthe aspera, Celtis sinensis) in most of the patches. Some ruderal herbaceous species dominated heavily disturbed clear-felled patches. This study suggests that canopy modification influences the subsequent colonization pattern. Furthermore, heterogeneous patches contribute to greater species diversity and dynamics in isolated woodlands.

Identification of enterococci using conventional biochemical tests are often tedious to perform in a routine diagnostic laboratory and may give equivocal results. This study evaluates the usefulness of ribotyping by DNA hybridisation to identify 68 members of the bacterial genus Enterococcus characterised by a conventional test scheme. DNA probes (830 bp in size) were derived from the 16S rRNA gene of E. coli or E. faecalis by PCR, labelled with horseradish peroxidase and used in Southern blot hybridisations of enterococcal DNA digested with EcoRI. Unique ribotypes were obtained for 11 different species using 12 Enterococcus type strains. Ribotyping identified 44 E. faecalis isolates, 19 E. faecium isolates, two E. durans isolates and one E. avium isolate in concordance with results of the biochemistry tests. Two isolates that had ribotype patterns identical to the E. faecium type strain were unable to be definitively identified by biochemical tests. The results show that ribotyping is able to differentiate between E. faecium and E. faecalis and may be useful for identifying other enterococci in the hospital setting. In addition, ribotyping using DNA probes and enhanced chemiluminescence is a safe and more reproducible alternative to radiolabelling RNA in a clinical microbiology laboratory.

Inhibition of phagosome lysosome fusion is a strategy used by several intracellular bacteria that grow within mammalian cells. It was shown recently that Legionella pneumophila possesses a cytolytic activity that results from the insertion of pores in the macrophage membrane upon contact, and that this activity requires the dot/icm, gene products, which are necessary for intracellular growth and phagosome trafficking. Other bacteria that inhibit phagosome lysosome fusion, such as Mycobacterium tuberculosis, demonstrate similar cytolytic activities, which suggests that formation of pores in the phagosome membrane may account for the defects observed in phagosome trafficking. In this study, we identify a new class of L. pneumophila mutant that retains the pore-forming activity found in virulent bacteria, but is defective in phagosome lysosome fusion inhibition and intracellular growth. These data indicate that cytolytic activity is not sufficient for L. pneumophila-induced alterations in phagosome trafficking. Rather, the pore may be a vehicle that facilitates delivery of bacterial-derived effector molecules to the host cell cytoplasm.

The concentration of human activity around this shallow, sheltered gulf ecosystem has led to conflict and competition over the use of marine and coastal resources. The gulf supports extensive areas of ecologically significant subtidal and tidal coastal wetlands, comprising seagrass meadows, mangroves and saltmarshes, with nine wetlands having recognized national importance. The wetlands support economic activities such as commercial and recreational fishing, tourism and aquaculture, and to a lesser extent, mineral and petroleum exploration and shipping. These environments and activities are threatened by the effects of land-based urbanization, coastal development, stormwater runoff effluent and industrial discharges, and the resultant decline in water quality and food-chain contamination. Marine activities can also have adverse effects (i.e., dredging, sea-dumping, overfishing, fishing methods, oil spills, antifoulants, ballast water introductions), including the developing aquaculture industry. The continued loss and degradation of marine and coastal wetlands in the gulf is exacerbated by inadequate protection measures, lack of integrated management structures and policies, and conflict between competing user groups. Strong policies and integrated decision making based on sound information is required for the equitable and sustainable use of these wetlands. Gulf-level management of multiple-uses would limit the cumulative impacts of human use and coastal development. There is a particular need to protect areas with high conservation value and for future research and marine conservation to focus on the coastal nearshore ecosystem. High priorities are coastal and biodiversity inventories, understanding of ecological processes, linkages between coastal and offshore habitats, and coastal spatial mapping and information systems.

While federal agencies have not used the methodology widely for assessing the value of these resources per se, federal damage assessment laws and regulations have been more explicit in terms of assessing nonuse values that have been damaged, particularly under CERCLA, the Clean Water Act, and the Oil Pollution Act. The underlying economic theory of contingent valuation is discussed, and applications of the method, which involves asking respondents how much they would be willing to pay or to accept a change in a specific good in a hypothetical market framework, are elucidated. The design of a typical contingent valuation survey is outlined, as are methods for measuring reliability, validity, and bias of the responses. Selected empirical critiques of the methodology are provided.

This distribution is described by the interindividual geometric standard deviation (GSD sub()i, which is intended to represent the variability in blood Pb concentrations for children exposed to similar environmental concentrations of Pb. The recommended default GSD sub()ifor Pb in the model is 1.6. Several methodologies are presented for calculating the site-specific GSD sub()i and the performance advantages and limitations of each are examined.

The farmers had been exposed for an extended period to mixed pesticides. Three different cytogenetic assays were performed: the standard chromosome aberration assay, the challenge assay, and the tandem-probe fluorescence in situ hybridization (FISH) assay. Each is described. Results showed that, compared to the controls, the banana farmers had a consistent increase in chromosome abnormalities in all measured categories as determined by the standard chromosome aberration assay, and significantly abnormal DNA repair responses as determined by the challenge assay. Results from the FISH assay, however, were not statistically different between the farmers and the controls. The results from the first two assays suggested that the farmers had been exposed to genotoxic agents.

A total of 86 children from southwest metropolitan Mexico City were used, along with 12 children as controls. Air samples were monitored for ozone, nitrogen dioxide, nitrogen oxides, sulfur dioxide, and suspended particulates. DNA damage was assessed by the single gel cell electrophoresis assay. Results showed that the children in the control group reported no nasal or respiratory symptoms, whereas the exposed children reported nasal obstruction, epistaxis, nasal dryness, cough, and chest discomfort. The mean nuclear staining for 8-OHdG in nasal cells was significantly different between the exposed and control groups. In addition, the percentage of nasal cells with DNA damage was increased in an age-dependent manner in the exposed children.

Water samples were collected and analyzed, and drinking-water consumption data were obtained by questionnaire. The median Cu values in the drinking-water samples were 0.52 and 0.80 mg/l for Malmo and Uppsala, respectively. Values tended to be highest in the morning and lowest in the evening. In Malmo, there was a considerable difference in Cu concentrations between areas according to a water source. The mean daily intake of drinking water was 0.62 l, and the median daily intake of Cu from drinking water was 0.32 mg. The median Cu concentration in drinking water was markedly lower in dwellings built between 1940 and 1960 than in those built before 1920.

During the 2-yr study, an IUGR birth was defined as one whose birth weight fell below the tenth percentile by gender and gestational week for the Czech Republic. The concentrations of particulate matter were measured continuously. Results showed that the daily concentrations of PM sub(10) and PM sub(2.5) ranged 4333 and 1332 mu g/m super(3), respectively. Both the medium and high exposures were statistically significant for both PM sub(10) and PM sub(2.5). Increases in IUGR were associated with PM sub(10) levels over 40 mu g/m super(3) and with PM sub(2.5) levels over 37 mu g/m super(3) during early pregnancy. Neither season nor year of survey were associated significantly with IUGR, but both appeared to be confounders.

Air-pollution data on particulates, carbon monoxide, sulfur dioxide, nitrogen dioxide, and ozone were collected and related to the emergency department visit data. Significant associations between increased emergency department visits for asthma and air pollution were found across the three utilization regions. The visits were associated significantly with concentrations of fine particles, PM sub(10), and CO. The PM sub(10) and CO data were found to be significant predictors of emergency department asthma visits in the low-utilization and for the combined utilization areas.

In addition, pesticide-transfer estimates were compared from carpet and furniture surfaces to skin using hand press and wipe sampling methods. All insecticide applications were conducted according to label instructions. Results showed that skin removed 0.040.69% of the chlorpyrifos deposited on surfaces by either broadcast or aerosol applications. Hand contact removed 39% of the amount measured by wipe sampling from carpet and 22% from furniture. Hand contact removed 36% of the amount measured by polyurethane foam roller sampling. Overall, the measurement methods substantially overestimated the amount of residue removed by skin contact.

Half of the women were under 30 yr of age and half were over. Results showed that at least one organochlorine was found in all samples, with p,p'-DDE found at the highest concentration, followed by beta -hexachlorocyclohexane. Of the PCBs, congeners 153/132 and 138/160 were present at the highest concentrations. The median endrin concentration was significantly higher in Kiyv, while the median concentrations of hexachlorobenzene, trans-nonachlor, oxychlordane, heptachlor epoxide, and many of the PCBs were significantly higher in women from Dniprodzerzhinsk. Older women tended to have higher levels of organochlorine compounds than younger women, especially p,p'-DDE, beta -hexachlorocyclohexane, hexachlorobenzene, trans-nonachlor, oxychlordane, and several PCB congeners. All concentration data are tabulated.

Questionnaires were used to determine the health status and breast-feeding pattern of the infants; the health status, food frequency pattern, smoking status, medication use, and residential history of the mothers; and the work history of the mothers and fathers. Six state farms were selected for the study based on their high birth and high infant mortality rates. The extensive resulting data are tabulated, which show that the TCDD concentrations were tenfold higher at the farms than background concentrations, and TCDD was the major contributor to the toxic equivalent values in the samples collected. Only the major residence was found to be a significant risk factor. The food chain was found to be widely contaminated, due to the use of cotton defoliants in the region.

It is a twin donor study, with one individual HIV super(+), the other HIV super(-) using a sample size of 4-6 pairs of HLA-identical twins. The study procedures will comprise one round of leukapheresis from the HIV super(-) twin followed by CD4 super(+) T lymphocyte isolation, retoviral transduction, cell expansion and infusion into the HIV super(+) twin. The harvested peripheral blood lymphocytes (PBLs) will be activated using OKT3 and IL-2, divided into two equal groups, and transduced with a replication-incompetent vector containing a neomycin-resistance gene (neo super(R)) or a vector containing a neo super(R)/ribozyme gene. The two cell populations will then be separately expanded with IL-2. These ex vivo procedures will all occur with a 'CellMax super(TM) Artificial Capillary Cell Culture System'. Both populations will then be infused into the HIV super(+) twin (approximately 10 super(9) CD4 super(+) T cells of each neo super(R) only and neo super(R)/ribozyme). Detection of the genetically marked cells (both integration and expression) will be via polymerase chain reaction (PCR) techniques. Frequent monitoring of the recipients will continue for a period of at least 24 weeks post-infusion and will continue indefinitely at regular intervals for assessment of the long-term safety of the procedure. This work is based on previous gene therapy protocols in the adenosine deaminase deficiency and HIV therapeutics areas. In addition, other clinical protocols, conducted in the USA have recently shown persistence, implying proliferation, of HIV super(-) T lymphocytes following infusion into HIV super(+) matched siblings.

Hearing of the Committee on Health, Education, Labor, and Pensions on Examining Various Strategies for Transforming the Forgotten Half into the Indispensable Foundation of the 21st Century Workforce and for Making Secondary Education the Centerpiece of Those Strategies. United States Senate, One Hundred Sixth Congress, First Session. AN - 62304055; ED449305 AB - This document records the oral and written testimony from a 1999 Senate Committee hearing on "the forgotten half"--young people who do not continue their education past high school and, in many cases, do not finish high school. Witnesses testified that there is a great need for persons with technical skills to fill existing and projected jobs in the United States, but that young people with the appropriate skills cannot be found. In response to this need, some witnesses suggested that more attention should be paid to high schools when Congress re-authorizes the Elementary and Secondary Education Act. Current legislation directs only 8 percent of the funds authorized by the act to high schools, although 28 percent of students are in high school. The witnesses asked for more funding for programs to improve high school teaching in technical areas and for minority and disadvantaged students, and to create innovative programs. Several witnesses profiled the programs in which they are involved, which have been successful in helping low-achieving students to acquire basic and technical skills and to advance to postsecondary education and to higher-wage employment.

Under favorable moisture conditions, A. dealbata grew at a rate close to (and sometimes exceeding) that of E. nitens, bringing about canopy closure by two years of age where A. dealbata stem frequencies were high. Competition peaked at age 2-6 years before declining as the A. dealbata canopy was suppressed, in part by intra-specific Acacia competition. E. nitens basal area was a highly significant inverse correlate of A. dealbata stem density from ages 2-8 years. However, a simple correlation between E. nitens and A. dealbata basal areas was significant only in young stands (age 2-4 years). The effects of early-age competition by A. dealbata on E. nitens productivity were substantial, reducing standing volume compared to Acacia-free plots by almost 25% by age eight years. Soil nitrogen status was positively correlated with A. dealbata presence at both ages sampled (four and eight years) and negatively correlated with E. nitens basal area. A. dealbata was, therefore, considered to be a net contributor of nitrogen during this period, but competition for other resources negated any positive effect of this contribution.

Hearing before the Committee on Education and the Workforce. House of Representatives, 106th Congress, First Session. AN - 62305833; ED446850 AB - In preparation for reauthorization of Even Start and other Federal education programs, these hearings transcripts recount testimony before the U.S. House Committee on Education and the Workforce concerning the Even Start and family literacy programs. Testimony was presented by: (1) the president of the National Center for Family Literacy, giving an overview of family literacy concepts and outlining the components of a quality family literacy program; (2) the director of the National Institute for Literacy, discussing the importance of evaluations of the Even Start program and the use of instructional programs based on scientific research; (3) a state manager for the Even Start program, discussing the importance of flexible Federal legislation to allow states to accomplish their family literacy goals; and (4) other local literacy program administrators. The transcripts' nine appendices contain written testimony. The testimony indicated that family literacy programs may help undereducated parents gain the skills they need to become self-sufficient and to help their children through school; the positive impact of such programs on families suggests that they can be an important strategy for student success. Recommendations for evaluation of Even Start programs included examination of the adult education component and better application of research findings on learning to read to the intergenerational approach.

The content of flavanols in the cells on the 6th day was approximately twice that of the control culture (31.9-60.7 mg/g dry wt). However, the contents of other secondary metabolites such as chlorogenic acid and gallic acid were not changed. The levels of flavanols in the culture medium remained unchanged throughout the 21-day culture period. Of the the inorganic components supplemented to the culture medium , only elevated levels of calcium chloride induced an increase in flavanol contents of the cells. The results indicated that the elevated concentration of calcium in the culture medium played an important role in activating the accumulation of flavanols.

Methods and results: In this paper we use Bradford Hill criteria to synthesize results from the biological and epidemiological literature in a formal assessment of the strength of support for such a relationship. Although we find that these criteria, designed for clinical trials, do not give an ideal framework for assessment of epidemiological and biological studies, nevertheless they do provide systematic guidance for this assessment. For the general population, of the nine tests proposed by Hill we find that one (biological plausibility) seems to be supported, though not unarguably; three (strength, consistency, specificity) appear to fail by accepted standards; and the remaining five have insufficient data for a clear evaluation (biological gradient, experimental evidence, temporality, coherence, analogy). Overall, this provides at best weak support for a causal association between ETS and IHD across the general community. Conversely, there appears to be more support, especially in the biology studies, for an association between ETS and IHD for those with pre-existing disease, although epidemiological studies are limited in this area. Conclusions: One of the outcomes of this review is the identification of areas of focus for future epidemiological and biological research. First, we find that stronger associations may be found in the particular subpopulation with pre-existing IHD. In this case, more convincing biological plausibility and experimental evidence indicate a need for relevant epidemiological studies, although individual responses are very variable. Second, we identify the need for further, more detailed evaluations of the nature of vessel wall thickenings occurring in experimental models of ETS exposure. Third, we propose long-term animal studies of initiation of IHD, including direct assessment of effects on the accumulation of lipid in vessel walls, at appropriate ETS exposure levels. Short abstract We use Bradford Hill criteria to synthesize the biological and epidemiological literature so as to assess formally whether ischaemic heart disease (IHD) is caused by exposure to environmental tobacco smoke (ETS). For the general population we find, at best, weak support for causality: of nine tests, one (biological plausibility) is supported, though not unarguably; three (strength, consistency, specificity) fail; and five (biological gradient, experimental evidence, temporality, coherence, analogy) have insufficient data for clear evaluation. For the population with pre-existing IHD the biological support is possibly stronger. We identify three areas for future research: epidemiological studies of those subpopulations with pre-existing IHD; evaluation of the nature of vessel wall thickenings occurring in experimental studies; and long-term animal studies of initiation of IHD, including direct assessment of effects on the accumulation of lipid in vessel walls, at appropriate ETS levels.

At the regional level viable biodiversity conservation requires a range of management strategies that may include the establishment of statutory protected areas, a range of off-park conservation management measures and achievable guidelines for ecologically sustainable land management at the landscape scale. Monitoring the performance of protected areas in achieving biodiversity conservation requires a commitment by government to facilitate involvement and participation of the wider community. Four Australian case studies discuss how public-private conservation partnerships are integrating sustainable land management and biodiversity conservation at the regional level.

The subsequent hybrid growth model was used to predict the time course of height and volume growth in 16 plantations of E. globulus located in northern Tasmania, Australia. Growth in these plantations was constrained by temperature, water stress, waterlogging and poor site nutrition. With the help of a few simple, easily obtained site descriptors, P RO M OD was used to predict the site index for these sites. This site index was used to run N IT G RO . Comparison of predictions with observed height and volume growth indicated that height growth was predicted accurately, but that estimates of volume growth were biased. The bias in the estimates of volume growth may be the result of the application of a growth model developed for E. nitens plantations to E. globulus plantations.

Narratives reveal significant differences in orientation to first birth according to women's social class, but also reveal significant shifts in identity & empowerment with subsequent births. Findings differ significantly from existing accounts of power relations in childbirth, which have tended either to universalize women, or, in more recent poststructuralist accounts, to abandon the notion of socially structured differences between women altogether. Results here indicate that social class has a strong effect on the shaping of identity, but these differences can be transcended by the experience of childbirth itself, which is a critical reflexive moment in many women's lives. 91 References.

AN - 21258817; 11702199 AB - The concentrations of environmental tobacco smoke (ETS) to which workers are exposed have been measured, using nicotine or other tracers, in diverse workplaces. Policies restricting workplace smoking to a few designated areas have been shown to reduce concentrations of ETS, although the effectiveness of such policies varies among work sites. Policies that ban smoking in the workplace are the most effective and generally lower all nicotine concentrations to less than 1 microg/m3; by contrast, mean concentrations measured in workplaces that allow smoking generally range from 2 to 6 microg/m3 in offices, from 3 to 8 microg/m3 in restaurants, and from 1 to 6 microg/m3 in the workplaces of blue-collar workers. Mean nicotine concentrations from 1 to 3 microg/m3 have been measured in the homes of smokers. Furthermore, workplace concentrations are highly variable, and some concentrations are more than 10 times higher than the average home levels, which have been established to cause lung cancer, heart disease, and other adverse health effects. For the approximately 30% of workers exposed to ETS in the workplace but not in the home, workplace exposure is the principal source of ETS. Among those with home exposures, exposures at work may exceed those resulting from home. We conclude that a significant number of U.S. workers are exposed to hazardous levels of ETS.

AN - 21258796; 11702198 AB - Mechanical systems are used in buildings to provide conditioned air, dissipate thermal loads, dilute contaminants, and maintain pressure differences. The characteristics of these systems and their operations h implications for the exposures of workers to environmental tobacco smoke (ETS) and for the control of these exposures. This review describes the general features of building ventilation systems and the efficacy of ventilation for controlling contaminant concentrations. Ventilation can reduce the concentration of ETS through dilution, but central heating, ventilating, and air conditioning (HVAC) can also move air throughout a building that has been contaminated by ETS. An understanding of HVAC systems is needed to develop models for exposures of workers to ETS.

AN - 21258027; 11703766 AB - This article is a description of the current situation in France with regard to occupational cancer: research, prevention, and occupation. Toxicologic experiments are carried out using (italic)in vitro(/italic) and (italic)in vivo(/italic) tests, particularly using transgenic mice. Several epidemiologic studies have been conducted over the last decades: population-based case-control studies; mortality studies and cancer incidence studies carried out in historical cohorts of workers employed in the industry; and case-control studies nested in occupational cohorts. French ethical aspects of toxicologic and epidemiologic studies are described. The results thus obtained are used to establish regulations for the prevention and the compensation of cancers attributable to occupational exposure. This French regulation for prevention of occupational cancer involves several partners: (italic)a(/italic)) the states authorities, including labor inspectors, responsible for preparing and implementing the labor legislation and for supervising its application, particularly in the fields of occupational health and safety and working conditions; (italic)b(/italic)) the Social Security Organisation for the analysis of present or potential occupational risks based on tests, visits in plants, complaints or requests from various sources, and statistics. These activities are performed within the framework of the general French policy for the prevention of occupational cancer. This organization includes the National Institute for Research and Safety, particularly involved in research in the various fields of occupational risks--animal toxicology, biologic monitoring, exposure measurements epidemiology, psychology, ergonomy, electronic systems and machineries, exposure to chemicals, noise, heat, vibration, and lighting; and (italic)c(/italic)) companies where the regulation defines the role of the plant manager, the occupational physician, and the Health, Safety and Working Conditions Committee (comprising the manager, employees' representatives, the occupational physician, and the safety department) in dealing with any problem regarding safety, occupational hygiene, and working conditions. These organizations along with medical practitioners are involved with the compensation of occupational cancers. The regulation for compensation includes the tables of occupational cancer, the possibility of recognition of a cancer case when the requirements of the tables are not met, and the postprofessional follow-up of workers exposed to a carcinogenic agent.

AN - 21256646; 11702200 AB - When using the mass balance equation to model indoor air quality, the primary assumption is that of uniform mixing. Different points in a single compartment are assumed to have the same instantaneous pollutant concentrations as all other points. Although such an assumption may be unrealistic, under certain conditions predictions (or measurements) of exposures at single points in a room are still within acceptable limits of error (e.g., 10%). In this article, three studies of the mixing of environmental tobacco smoke (ETS) pollutants are reviewed, and data from several other ETS field studies are presented. Under typical conditions for both short sources (e.g., 10 min) and the continuous sources of ETS in smoking lounges, I find that average exposure concentrations for a single point in a room represent the average exposure across all points in the room within 10% for averaging times ranging from 12 to 80 min. I present a method for determining theoretical estimates of acceptable averaging times for a continuous point source.

AN - 21250986; 11704972 AB - The knowledge of specific problems of occupational cancer in Spain is scarce. The environment of the workplace has improved over the last few years after a long period distinguished by bad working conditions, incomplete legislation, and insufficient safety measures and control. It has been estimated that 3,083,479 workers (25.4% of employees) were exposed to carcinogens. The most common occupational exposures to carcinogenic agents were solar radiation, environmental tobacco smoke, silica, and wood dust. The highest number of employees were exposed to silica crystalline (404,729), diesel engine exhaust (274,321), rubber products (99,804), benzene (89,932), ethylene dibromide (81,336), agents used in furniture and cabinet making (72,068), and formaldehyde (71,189). The percentage of total cancer deaths attributed to occupational exposure was 4% (6% in men, 0.9% in women). Compared with other European countries, the incidence of lung cancer and leukemia in Spain are one of the lowest, but it is rapidly increasing. The incidence of urinary bladder and larynx cancer, on the contrary, are one of the highest. Few studies on occupational cancer have been conducted in Spain. The main problems are the availability of death certificates and the quality of the information on occupation in mortality of statistics. It is necessary to improve methods of assessment of exposures using expert hygienists and biologic markers of exposure and diseases. Reduction of cancer by limiting or avoiding exposure to known occupational carcinogens is still necessary.

Bio-acidification produced a highly acidic and digestive environment which, accompanied by shifting microbial populations, accelerated the mineralisation of organic nitrogen and the leaching of phosphorus and heavy metals. The bio-acidification process was capable of leaching significant quantities (7-98%) of Ni, Zn, Pb, Cr, Cd, and Cu from sludge, however nitrogen and phosphorus were also leached simultaneously. It should be emphasised however that bio-acidification by itself did not reduce the TKN, total phosphorus, or heavy metal contents of the sludge. The separation of supernatant containing the leached products resulted in a significant loss in the nutrient value of the sludge. The measured organic nitrogen mineralisation results were in the range of 10-43%. Similarly for phosphorus, the leaching results were in the range of 16-65%. The phosphorus leaching results in individual sludge samples were significantly higher than the nitrogen leaching results. This is because the digestion of organic matter is the main cause of TKN mineralisation, while in addition, phosphorus leaching is possibly increased by the leaching of phosphorus from inorganic sources and polyphosphates stored in sludge. This study confirmed that while bioacidification can be used to reduce the heavy metal contents in sludge, the process can also reduce the nitrogen and phosphorus values of the product.

The resurgence of V. cholerae O139 during 1995 after its transient displacement by a new clone of El Tor vibrios demonstrated rapid changes in the epidemiology of cholera in Bangladesh. A recent outbreak of cholera in two north-central districts of Bangladesh caused by V. cholerae O139 led us to analyze strains collected from the outbreak and compare them with V. cholerae O139 strains isolated from other regions of Bangladesh and neighboring India to investigate their origins. Analysis of restriction fragment length polymorphisms in genes for conserved rRNA (ribotype) revealed that the recently isolated V. cholerae O139 strains belonged to a new ribotype which was distinct from previously described ribotypes of toxigenic V. cholerae O139. All strains carried the genes for toxin-coregulated pili (tcpA and tcpI) and accessory colonization factor (acfB), the regulatory gene toxR, and multiple copies of the lysogenic phage genome encoding cholera toxin (CTX Phi ) and belonged to a previously described ctxA genotype. Comparative analysis of the rfb gene cluster by PCR revealed the absence of a large region of the O1-specific rfb operon downstream of the rfaD gene and the presence of an O139-specific genomic region in all O139 strains. Southern hybridization analysis of the O139-specific genomic region also produced identical restriction patterns in strains belonging to the new ribotype and those of previously described ribotypes. These results suggested that the new ribotype of Bengal vibrios possibly originated from an existing strain of V. cholerae O139 by genetic changes in the rRNA operons. In contrast to previously isolated O139 strains which mostly had resistance to trimethoprim, sulfamethoxazole, and streptomycin encoded by a transposon (SXT element), 68.6% of the toxigenic strains analyzed in the present study, including all strains belonging to the new ribotype, were susceptible to these antibiotics. Molecular analysis of the SXT element revealed possible deletion of a 3.6-kb region of the SXT element in strains which were susceptible to the antibiotics. Thus, V. cholerae O139 strains in Bangladesh are also undergoing considerable reassortments in genetic elements encoding antimicrobial resistance.

Personal inhalable and respirable dust sampling was carried out. The lung function tests of workers were conducted before and after a workshift. The mean percentage cross-shift decrease in lung function was markedly high for woodworkers compared with the controls. Dose-response relationships among personal exposures and percentage cross-shift decrease in lung function and percentage predicted lung function were more pronounced among joinery workers compared with sawmill and chip mill workers. Woodworkers had markedly high prevalence of regular cough, phlegm, and chronic bronchitis compared with controls. Significant associations were found between percentage cross-shift decrease in FVC and regular phlegm and blocked nose among sawmill and chip mill workers. Both joinery workers and sawmill and chip mill workers showed significant relationships between percentage predicted lung function (FVC, FEV sub(1), FEV sub(1)/FVC, FEF sub(25-75%)) and respiratory symptoms. Wood dust and biohazards associated with wood dust are potential health hazards and should be controlled.

The effective removal cross sections for the foregoing individual shielding materials as well as their combinations are obtained from transmission data using two-group neutron fluxes defined by a Cd-cutoff value. The experimental transmission factors for I-M concrete and polyboron are compared with those obtained from transport calculations performed with the ANISN deterministic code in the forward mode and the MCNP4B Monte Carlo code. The ANISN code is used for the fast neutron group flux (Cd-cutoff flux), and the MCNP4B code is used for the total neutron flux. The agreement between the experiment and calculation is fairly good at deep penetration, but at initial points, some disagreement is observed. This observation is valid for both polyboron and I-M concrete.

Although these potentially cleavable junctions are ubiquitous, they are often protected from deoxyribozyme activity by RNA secondary structure. We have developed a multiplex cleavage assay for screening the entire length of a target RNA molecule for deoxyribozyme cleavage sites that are efficient, both in terms of kinetics and accessibility. This strategy allowed us to simultaneously compare the RNA cleaving activity of 80 deoxyribozymes for a model target gene (HPV16 E6), and an additional 60 deoxyribozymes against the rat c-myc target. The human papilloma virus (HPV) target was used primarily to characterize the multiplex system and determine its validity. The c-myc target, coupled with a smooth muscle cell proliferation assay, allowed us to assess the relationship between in vitro cleavage efficiency and c-myc gene suppression in cell culture. The multiplex reaction approach streamlines the process of revealing effective deoxyribozymes in a functional assay and provides accessibility data that may also be applicable to site selection for other hybridization-based agents.

For gel fermentations fungal growth decreased as rotational speed increased, presumably due to increased shear. For wheat bran fermentations fungal growth improved under agitated compared to static culture conditions, due to superior heat and mass transfer. We conclude that the effects of operational variables on the performance of SSF bioreactors are mediated by their effects on transport phenomena such as mixing, shear, heat transfer, and mass transfer within the substrate bed. In addition, the substrate characteristics affect the need for and the rates of these transport processes. Different transport phenomena may be rate limiting with different substrates. This work improves understanding of the effects of bioreactor operation on SSF performance.

Urine Hg levels were also determined. Results showed that the high-exposure group committed significantly more errors on the computerized handeye fine motor coordination test than the low-exposure group, but no significant differences between the groups were noted on any other measures of neurobehavioral performance or psychological distress. Only the correlation between urine Hg concentration and errors on handeye coordination was significant. Significant levels of psychological stress were found, however, with 84% of the subjects reporting a clinically diagnostic level of distress.

The excurrent ducts of animals treated neonatally with octylphenol, bisphenol A, and parabens were also examined at concentrations approaching their maximum solubility in oil. Testis weights were compared between control and cohorts at 18, 25, 35, and 75 d of age. Results showed that treatment with diethylstilbestrol caused dose-dependent changes in testis weight, which were most pronounced on days 18 and 25. Similar changes were observed in animals exposed to ethinyl estradiol and tamoxifen, but differences in dose responses compared to diethylstilbestrol were observed. The weakly estrogenic compounds caused minor but significant decreases in epithelial cell height of the efferent ducts at days 18 and 25, but these changes were not observed at day 35. The data suggested that the impairment of excurrent ducts by neonatal estrogen exposure was probably due to direct, rather than indirect, effects.

Results showed that vitellogenin levels in the males increased with increasing OP exposure concentration, but levels declined after mating in clean water. The control males and females produced approximately twice as many eggs as the OP-exposed males and unexposed females. Logic regression analysis revealed that increasing OP concentrations were correlated significantly negatively with the percent of eggs fertilized by exposed males. In the embryos of all treatment groups, increasing occurrence of developmental anomalies was detected. In males exposed to OP concentrations greater than 41 ppb, an increase in primary and secondary spermatogonia was observed compared to controls.

None of the middle-aged and elderly men had occupational Pb exposures. Results showed that patella Pb was significantly higher than tibia Pb. Erythrocyte Pb exhibited the strongest correlation with urine Pb, followed by the creatinine clearance rate, patella Pb, and tibia Pb. Body weight was negatively correlated with patella and tibia Pb, and positively correlated with creatinine clearance rate and urine Pb.

AN - 14514918; 10570572 AB - Maps depicting the extent of forest spraying of the insecticide, Matacil 1.8D, were obtained from the Canadian Wildlife Service, and information on Atlantic salmon Salmo salar were obtained from the Canadian Atlantic Fisheries Scientific Advisory Committee. The overlap of the information was then used to assess the possible impacts of pesticide exposure on fish stocks. Results are presented specifically for the Restigouche River basin and for the region as a whole. A significant negative correlation was found between the returns of salmon and the proportion of tributaries sprayed within the basin in 1977. For the larger region, a significant proportion of the lowest salmon catches also coincided with Matacil 1.8D spraying. Relationships between fish catches and fenitrothion or Matacil 1.8F were not observed, which suggested that the causal agent was 4-nonylphenol, which is a known xenoestrogen in Matacil 1.8D.

Between 1989 and 1996, 18 such storms were identified, which were then correlated with mortality data. Results showed that the average PM sub(10) level on exposure days was 221 mu /m super(3) higher than on control days, whereas carbon monoxide levels were much lower during the exposure periods. The mean daily death count was slightly lower on the exposure days than on the control days, which was also found when the day following the storm was included in the analysis. If coarse particles were equally as toxic as combustion particles, a 20% increase in daily mortality would have been expected.

The results were compared to those obtained using scanning electron microscopy of ashing residue. Results showed that fibers of all three types were deposited in small airways and alveolar septa. Long amosite asbestos fibers frequently penetrated into alveolar septa as far as the interstitium. Both arithmetic and geometric mean lengths of the man-made vitreous fibers in aerosol were typically longer than those of retained fibers, whereas amosite fibers of all lengths were equally likely to reach parenchyma. The man-made fibers appeared to be affected by both lung filtration and fiber degradation, whereas amosite was not. With only two exceptions, fiber burdens estimated by ashing and scanning electron microscopy were greater than those estimated by in situ confocal laser scanning microscopy.

The aim of the framework is to identify the key plausible links and interactions that may influence the potential effect of climate change on diseases, with climate change conceived as manifesting itself in each of three interrelated modules: changes in transmission biology, ecologic changes, and sociologic changes. A literature review is presented of selected studies that either directly or indirectly have addressed climate-change impacts on infectious diseases, such as malaria, dengue fever, cholera, and other disease vectors, as well as the ecologic and social factors influencing diseases and methods of adaptation and control.

Specific sex differences in constitutive steroid biotransformations were identified, and the role of androgens in the regulation of these activities was determined. The activity that would serve best as a biomarker of exposure was then assessed, and the biomarker was validated using organisms exposed to xenobiotics that either act as androgen antagonists or modulate endogenous androgen levels. Results showed that the testosterone 6 alpha /15 alpha -OH ratio could serve as a sensitive biomarker of androgen disruption in the mouse model. In contrast to the variability reported in serum testosterone concentrations in control mice, variation of the ratio ranged 1.631%. The ratio not only detected effects of a chemical on endogenous androgen levels, but also responded to antiandrogenicity of a chemical. However, the ratio could not be applied universally to all species.

The cohort was assembled from historical ward membership records of the Church of Jesus Christ of Latter-day Saints. Community drinking-water As concentrations were determined from historical records of As measurements maintained by the state of Utah dating back to 1964. Arsenic exposure was categorized as low, medium, and high over a 20-yr period. Results showed that deaths from hypertensive heart disease and nephritis and nephrosis were significantly elevated in the cohort males compared to Utah as a whole, while deaths from arteriosclerosis and benign neoplasms were increased in the cohort, but not statistically so. Similar results were found for females. Among males, prostate cancer was increased significantly in the cohort, and death due to kidney cancer was elevated in the medium- and high-exposure groups. No cancer causes of death for females were elevated significantly in the cohort.

Several lines of evidence suggest that methane gas seeping from unstable methane hydrates supports a newly discovered microbial community, which is unusual both in its genetic relationships and in its metabolism. The concept of microbial diversity has been transformed by the growth in sequence data from ribosomal RNA (16S rRNA). The cloning and sequencing of RNA from microbes living in their natural environments has revealed a genetic diversity beyond the dreams of researchers whose tools were limited to microscopy and cell culturing. RNA molecular probes have revealed previously unknown evolutionary lineages, as well as associations between the genetic structure of communities and their ecophysiology. As Hinrichs and co-workers have shown, 16S rRNA cloned from shallow sediment samples above unstable methane hydrate deposits in the Eel River basin, offshore California, is dominated by a variety of previously unknown genes from archaea, which along with bacteria and eukaryotes comprise the three domains of life on Earth. These were accompanied by sequences from known anaerobes, including sulphate-reducing and Gram-positive bacteria. There were two main types of archaea discovered in the seep sediments, with some clones closely related to known methanogens (anaerobic methane-producing bacteria) of the order Methanosarcinales. Most sequences, however, were from a new and closely similar group that was distinct from, but related to, the methanogenic orders Methanomicrobiales and Methanosarcinales. Besides being distinguishable from known methanogens, these new organisms also had sequences unlike any cloned from contemporary freshwater and marine environments.

Asteroids were exposed to dilutions of water-accommodated fractions (WAF) of Bass Strait stabilised crude oil (control, 2%, 10%). Effects of exposure (4 d) and depuration (20 d) were quantified using circular statistical analyses. Observations suggested that disruption of behaviour might be concentration-dependent. Control asteroids successfully located mussels during tests. A small proportion (3 of 16) of asteroids exposed to 2% WAF also located the mussels, while asteroids exposed to 10% WAF did not. Following depuration, exposed asteroids recovered their chemoreception capacities. It is concluded that (1) Coscinasterias muricata is able to locate prey mussels through chemoreception, (2) exposure to oil disrupts its foraging behaviour, and (3) the effect is reversible.

Statistical Analysis Report. AN - 62486706; ED428780 AB - This report presents two approaches to measuring inflation for public libraries: (1) an approach based on a fixed-market-basket (FMB) of the prices of library inputs, which yields a public library input cost index (PLICI), and (2) an approach based on an econometric model of library services and costs, which yields a public library cost of services index (PLCSI). The PLICI represents essentially a weighted average of the series of public library input prices, while the PLCSI places emphasis on the cost of producing library services. Contains the following chapters: Chapter 1 "Introduction"; Chapter 2 "Conceptual Framework" which describes the PLICI and the PLCSI approaches in some detail. Chapter 3 "Empirical Analysis of a Public Library Input Cost Index" offers an empirical analysis of the PLICI, including an analysis of budget shares and input cost series. Chapter 4 "Empirical Analysis of Public Library Operating Expenditures and Development of the Public Library Cost of Services Index" presents the PLCSI. Chapter 5 "Concluding Remarks" concludes the report by comparing the inflation index derived from the PLCSI with that from the PLICI and suggests ways of improving the public library indexes. Thirty-two tables and indexes present statistics. A glossary is provided. Appendices include technical notes, various descriptive statistics and parameter estimates for the variables used in the regression analysis, and standard errors. (AEF) AU - Chambers, Jay C.

Holistic and Mechanics Scores in 1984 and 1996. AN - 62476538; ED430246 AB - Supplementary to "NAEP 1996 Trends in Academic Progress," this report describes two aspects of writing for which change has been measured since 1984: writing fluency as determined by holistic scoring; and mastery of the conventions of written English as determined by mechanics scoring. The introduction discusses the layout and means of evaluation: measuring fluency of writing, mechanics of writing, and expressing the differences in performance. Chapter 1 compares holistic scores in 1984 and 1996 regarding student writing fluency in informative, persuasive, and narrative writing. Chapter 2 compares mechanics scores in 1984 and 1996 to look at overall characteristics of the papers, use of sentence types, control of sentence structure, and control of word-level and punctuation conventions. A summary includes discussion of fluency in writing, grammar, spelling, and punctuation, and observations made from the research. Appendixes present an overview of scoring procedures, scoring guides, and tables with standard errors.

The first '(1+ abundance data)' assumes that the N sub(4)/P sub(4) and BEB estimates are absolute indices of 1+ abundance whereas the other '(0+ abundance data)' assumes that these estimates are absolute indices of 0+ abundance (i.e. calves are assumed to be counted during the surveys at Point Barrow). The data included in the likelihood function are the percentages of calves and mature animals from 1985-92 and the abundance indices.

The species was introduced to this subantarctic island by sealers during the 19th century. The rats are now widespread and abundant in coastal areas all around the island. The distribution of rat populations is divided into discrete units by the availability of suitable habitat which, in turn, is a consequence of the rugged topography, particularly on the west coast. Rats are found from almost sea level to 200-250 m a.s.1. and up to 1 km inland. They have adapted successfully to the rigorous climate and firmly occupy a habitat niche in an environment where food is plentiful, predators are few and interspecific competition minimal. The principal habitat, tall Poa foliosa tussock grassland, provides year-round shelter and food. Rats dig burrows in the peaty stools of the tussock plants and construct nesting chambers at the base of the dense leaf canopy. Predictably, this provides a warmer and more stable thermal environment than that experienced outside under the tussock canopy where the runs are located. Tussock grasslands are spreading under the influence of management control measures directed at the introduced European rabbit and possibly global warming. Management programmes are also directed towards the eradication of feral cats. In response, rat populations may be expected to expand in numbers and to occupy new territories. Without control this may, in the long term, have serious consequences for the island's avifauna, particularly the smaller, burrow-nesting species.

Death from drowning of children can be expected to be a problem in Bangladesh give the geographical features of the country. Objective The objectives of this study are to determine the trend, pattern and correlates of drowning deaths. Methods Data are presented on deaths of children (1-4 years) due to drowning derived from a longitudinal, population-based surveillance system in operation in a rural area of Bangladesh in 1983-1995. Moreover, a case-control study was carried out to identify the risk factors associated with drowning. Results Deaths due to drowning ranged from about 10% to 25% of child deaths during 1983-1995. The absolute risk of dying from drowning remained almost the same over the study period but the proportion of drownings to all causes of death has increased. Drowning is especially prevalent in the second year of life. Age of the mother and parity have a significant impact on drowning. The risk of dying from drowning increases with the age of mother and much more sharply with the number of living children in the family. Two socioeconomic variables did not have an influence on the risk of drowning. Conclusions A substantial proportion of child deaths could be averted if parents and other close relatives paid more attention to the safety of children. The Child Health Programme of the Ministry of Health and Family Welfare of Bangladesh should develop health education programmes for villagers alerting them to the dangers of drowning and measures to prevent it.

Current ice concentration algorithms perform poorly in regions of predominantly thin or highly fragmented ice, which constitute a significant proportion of the pack in East Antarctica. The impact of the sea ice cover on high latitude air-sea interactions and marine ecology depends not only on ice extent and concentration but also on the ice-type composition of the pack. An unsupervised ice classification scheme, using data from four channels of the SSM/I, is presented and tested as a means of gaining important additional, complementary information on surface type. Class interpretation is by comparison with AVHRR, ERS-1 SAR, and near-coincident digital aerial photography and in situ data. The classification does a reasonable job at consistently differentiating the large-scale constituent regimes, including the outer marginal ice zone, the interior pack, and a transition zone separating the two. Given the short period of data analyzed, the cluster maps appear to be generally coherent and consistent through time as the pack changes in response to synoptic-scale atmospheric forcing, although the robustness of the technique needs further testing over longer time periods. An observed crossover in the meridional brightness temperature profiles is a dominant and consistent feature which marks the transition from unconsolidated and wet ice in the marginal ice zone to more consolidated ice with a thicker and drier snow cover in the interior pack. Ambiguities occur at the boundaries of some of these regimes due to sensor resolution limitations and the mixing of different ice types and open water. Also, some ice classes (like brash ice) cannot be distinguished from forming pancake ice. Furthermore, although the signature of the inner pack is usually distinct from that of the outer pack, we observed one extraordinary swell propagation event which led to ice fracturing and surface wetting, and significantly altered the surface classification. The results of this multiparameter study underline the importance of using multisensor systems synergistically to improve interpretation of passive microwave data and better characterize the complex Antarctic pack.

G. vaginalis lysates were found to significantly stimulate HIV expression in monocytoid cells. Stimulation was significantly higher when lysates were heated at 100 degree C for 5 min but was reduced by treatment with lysozyme or protease. G. vaginalis lysates also activated HIV expression in certain T cell lines. G. vaginalis lysates activated HIV long-terminal repeat transcription in HIV-infected cells and increased NF- Kappa B binding activity, indicating an effect by G. vaginalis on HIV transcription. The activation of HIV production by G. vaginalis suggests that genital tract infection with G. vaginalis increases the risk of HIV transmission by increasing HIV expression in the genital tract. This may explain, at least in part, the increased rate of HIV transmission in women with BV.

The Tasmanian Infant Health Survey was a prospective cohort study undertaken from 1988 to 1995. It involved 9,826 infants (89% of eligible infants) at higher risk of SIDS. Subsequently 53 eligible infants died of SIDS. Hospital interviews were available on 51 and home interviews on 35 SIDS infants. Urinary cotinine assays were conducted using gas-liquid chromatography (n = 100). Within a predictive model that explained 63% of urinary cotinine variance, the strongest predictor of cotinine and also of SIDS was maternal smoking, though the effects of prenatal and postnatal smoking could not be separated. However, for particular smoking-related behaviors, there was a discordance between prediction of cotinine concentration and prediction of risk of SIDS. If smoking mothers did not smoke in the room with the baby, the cotinine level in the infant's urine was reduced by a little more than a half (p = 0.009), but this was not associated with a reduction in SIDS risk (odds ratio = 1.09, 95% confidence interval 0.47-2.55). Similarly, the presence of other adult resident smokers was associated with a 63% increase in urinary cotinine (p = 0.047) but not with increased SIDS risk (odds ratio = 0.69, 95% confidence interval 0.34-1.40). However, the study lacked the power to detect modest effects, that is, those altering risk less than twofold.

The motivation for this stems from a desire to increase the Australian plantation estate, in part for commercial forestry and in part as a net sink of CO sub(2), and as a possible tool to lower the water table in regions prone to salinity. Thus, the plan to increase the plantation estate is driven by ecological concerns. PROMOD, a simple model for predicting plantation productivity following canopy closure, was used to examine the economics of growing Eucalyptus globulus under irrigation at Deniliquin, a site with mean annual rainfall 385 mm and mean total pan evaporation 1765 mm. It was assumed that nutrients were not limiting. Productivity increases with the total annual irrigation I (Ml ha super(-1) year super(-1)) and attains a maximum at some I determined by frequency of application. Maximum productivity (42 m super(3) ha super(-1) year super(-1)) requires I greater than or equal to 12 Ml ha super(-1) year super(-1) as weekly applications in amounts proportional to the current pan evaporation. Profitability was defined as the annual increase in wood value due to volume growth less irrigation costs, and was used to rank irrigation strategies. In general, profitability has a well-defined maximum and depends on frequency of application. Maximum profitability ($640 ha super(-1) year super(-1)) requires I approximately 12 Ml ha super(-1) year super(-1) as weekly applications in proportion to pan evaporation. Reduction of I or of frequency of application results in a major loss of productivity and profitability. Output from PROMOD was used as the basis for a more detailed discounted cash-flow analysis of a sawlog regime which confirms the better economics of high total-irrigation, high irrigation-frequency options. Available soil water capacity does not affect the total annual irrigation required for maximum profitability, but shallow soils do require more frequent, smaller applications of water. Reducing irrigation efficiency (which takes into account losses inherent in the irrigation method) from 1 to 0.5, doubles the total irrigation required for maximum profitability and reduces profitability by 70%. The results of this study have major implications. Serious consideration should be given to frequent irrigation of plantations in dry regions. The establishment and analysis of irrigated trials in regions of high VPD will have important benefits in understanding tree growth under such conditions and will provide data for validation of models under the extreme conditions that prevail in regions which might be economically exploited in the future.

DTPA was measured using ion-interaction reversed-phase liquid chromatography at 0 h (t sub(0)) and 24 h (t sub(24)). DTPA consistently eluted at approximately 3.3 min. Actual DTPA concentrations corresponded well with nominal concentrations, justifying the use of nominal concentrations for previous ecotoxicological bioassays. There was no significant degradation of DTPA either when uncomplexed or ferric-complexed, over 24 h (P > 0.05). In addition, there was no difference in DTPA and Fe(III)-DTPA degradation between MS synthetic medium and WLW (P > 0.05). Therefore, the previously reported decrease in DTPA toxicity, when complexed with iron was concluded not to be due to enhanced DTPA degradation. However, the presence of what appeared to be a degradation product in all Fe(III)-DTPA samples after 24 h, indicated that DTPA might be more susceptible to degradation when complexed with iron, as reported by other researchers.

Beyond this fundamental goal, the practice of chlorination involves maintaining a disinfectant residual in the distribution system to minimise biofilm formation and as an additional safeguard against pathogen intrusion. In contrast to many European countries the disinfectant residuals typically maintained in the distribution system are relatively high. The primary factors that are driving high disinfectant residuals include regulation, and using chlorine as a primary disinfectant rather than other advanced treatment systems. Lower disinfectant residuals are likely in the future with changes in regulations, installation of advanced treatment processes, and improvements in the distribution system.

The deduced amino acid sequences revealed that ChiA, ChiB and ChiC exhibited similarities to chitinases belonging to family 18 of the glycosyl hydrolases while ChiP and ChiQ belonged to family 20. ChiP and ChiQ showed different enzymic activities against fluorescent chitin analogues, but neither was able to degrade colloidal chitin. ChiA possessed chitinase activity but did not bind chitin; ChiB bound chitin but had no chitinase activity; ChiC possessed strong chitinase activity and also bound chitin. Production of ChiC in S91 appeared to be controlled by chiA expression, since insertion of a transposon into the ORF of chiA resulted in the loss of chitinase activity as well as loss of ChiC proteins in a chitinase-negative mutant. In Escherichia coli, ChiC appeared to be expressed from its own promoter. The GenBank accession numbers for the sequences reported in this paper are AF007894 (chiA), AF007895 (chiB), AF007896 (chiC), AF072375 (chiP) and AF072374 (chiQ).

Of 829 employees, 89 (10.7%) tested positive, with those handling livestock being more likely to have been exposed to Q fever than employees in low-risk occupations. This difference reached statistical significance (P < 0.01) when employees with other risk factors for exposure to Q fever were excluded. Veterinarians, stock inspectors, and regulatory officers had the highest risk of previous exposure. This study confirms that Q fever is a disease related to occupations that involve handling livestock, and it provides a basis upon which to promote vaccination of agricultural workers.

Seedlings from provenances from the middle of the altitudinal ranges of all species were capable of survival for 18 months on sites dominated by the other two species. However, 9 years after planting E. ovata had died out in open vegetation on all sites. In contrast, E. rodwayi had survived in open vegetation on all sites and was the sole or major survivor in the two lower altitude areas. E. gunnii had performed marginally better than E. rodwayi in the open vegetation at the highest altitude site, had survived in the E. rodwayi site and had died out in the E. ovata site. The results of field trials, and experiments in the glasshouse and laboratory, suggested that E. ovata is absent from open vegetation at the higher altitudes because of its susceptibility to frost, that E. rodwayi dominates the middle altitudes because of its superior frost resistance, that E. gunnii dominates the highest altitudes because of superior growth rates to E. rodwayi in misty and cool conditions, and that E. ovata is dominant at low altitudes because of its superior growth rates in warm conditions. Recent climatic changes are posited to have had some effect on the results of the field experiment.

Using allozyme markers, we examined the genetic diversity and structure of 16 fragmented populations. The species had high genetic variation compared to other plant species, and both polymorphism and allelic richness showed strong positive relationships with log reproductive population size, reflecting a loss of rare alleles (frequency of q < 0.1) in smaller populations. Fixation coefficients were positively related to size, due either to a lack of rare homozygotes in small populations or to Wahlund effects (owing to spatial genetic structure) in large ones. Neither gene diversity nor heterozygosity was related to population size, and other population parameters such as density, spatial contagion, and isolation had no apparent effect on genetic variation. Genetic divergence among populations was low (F sub(ST) = 0.17) and interpopulation gene flow was high (Nm = 2.8), despite a large north-to-south break in the species' current distribution. To preserve maximum genetic variation, conservation strategies should aim to maintain the five populations larger than 5000 reproductive plants, all of which occur in the north of the range, as well as the largest southern population of 626 plants at Truganina. Only one of these is currently under formal protection. High heterozygosity in smaller populations suggests that they are unlikely to be suffering from inbreeding depression and so are also valuable for conservation. Erosion of allelic richness at self-incompatibility loci, however, may limit the reproductive capacity of populations numbering less than 20 flowering plants.

We show that E. striolata, which does produce scat piles, and E. inornata, which does not, can both discriminate their own secretions, on paper substrates, from those of unfamiliar conspecifics. This was indicated by elevated tongue flick rates and more time in contact with the unfamiliar stimulus. This was not just a response to a novel stimulus because the secretions from another species (E. stokesii) elicited lower responses. When scats were presented, only striolata demonstrated discrimination between their own scats and those of unfamiliar conspecifics. This suggests that scats could be used to produce individual signals, perhaps indicating residence status, in scat-piling species. For striolata the signal from scats became less effective as the scats became older, suggesting the need to pile scats to renew the signal.

We investigated the involvement of monocyte chemoattractant protein-1 (MCP-1) in a rabbit model of T cell-mediated pulmonary granulomatosis. Intravenous injection of Propionibacterium acnes (P. acnes) into sensitized rabbits induced massive and diffuse pulmonary granulomas. Levels of MCP-1 in sera and bronchoalveolar lavage fluids (BALF) peaked before the granuloma formation reached the peak (on days 1 and 3 after challenge, respectively). Chemotactic activities toward monocytes and T cells in BALF were inhibited by anti-MCP-1 IgG by 80 and 36%, respectively. The phenotypic analysis of the migrating T cells revealed that activated and memory T cells rather than naive cells were preferentially attracted to the BALF. Administration of anti-MCP-1 antiserum inhibited the development of granuloma formation in both size and number, the numbers of infiltrating leukocytes in BALF, the expression of adhesion molecules on peripheral monocytes/T cells, and on macrophages/T cells in BALF, and the production of TNF- alpha in the lung. Anti-MCP-1 resulted in a trend toward decreased level of IL-1 beta in the lung. The inhibition of the production of these cytokines appeared to be induced indirectly through the inhibition of the recruitment of macrophages that produce these cytokines. The results suggest important roles of MCP-1 in the development of granuloma formation in this model through the attraction and activation of specific types of cells.

Periodic monitoring of the antimicrobial susceptibility profile of Neisseria gonorrhoeae in a high-risk population provides essential clues regarding the rapidly changing pattern of antimicrobial susceptibilities. A study concerning the prevalence of gonococcal infection among CSWs was conducted in Bangladesh. The isolates were examined with regards to their antimicrobial susceptibility to, and the MICs of, penicillin, tetracycline, ciprofloxacin, cefuroxime, ceftriaxone, and spectinomycin by disk diffusion and agar dilution methods. The total plasmid profile of the isolates was also analyzed. Of the 224 CSWs, 94 (42%) were culture positive for N. gonorrhoeae. There was a good correlation between the results of the disk diffusion and agar dilution methods. Some 66% of the isolates were resistant to penicillin, and 34% were moderately susceptible to penicillin. Among the resistant isolates, 23.4% were penicillinase-producing N. gonorrhoeae (PPNG). 60.6% of the isolates were resistant and 38.3% were moderately susceptible to tetracycline, 17.5% were tetracycline-resistant N. gonorrhoeae, 11.7% were resistant and 26.6% had reduced susceptibility to ciprofloxacin, 2.1% were resistant and 11.7% had reduced susceptibility to cefuroxime, and 1% were resistant to ceftriaxone. All PPNG isolates contained a 3.2-MDa African type of plasmid, and a 24.2-MDa conjugative plasmid was present in 34.1% of the isolates. Since quinolones such as ciprofloxacin are recommended as the first line of therapy for gonorrhea, the emergence of significant resistance to ciprofloxacin will limit the usefulness of this drug for treatment of gonorrhea in Bangladesh.

Consequently, these bacteria have evolved a variety of often-redundant high-affinity acquisition systems to obtain iron in this restricted environment. We have identified an iron transport system that is encoded within the centisome 63 pathogenicity island of Salmonella typhimurium. The nucleotide composition of this locus is significantly different from that of the rest of this pathogenicity island, suggesting a different ancestry and a mosaic structure for this region of the S. typhimurium chromosome. This locus, designated sit, consists of four open reading frames which encode polypeptides with extensive homology to the yfe ABC iron transport system of Yersinia pestis, as well as other ABC transporters. The sitA gene encodes a putative periplasmic binding protein, sitB encodes an ATP-binding protein, and sitC and sitD encode two putative permeases (integral membrane proteins). This operon is capable of complementing the growth defect of the enterobactin-deficient Escherichia coli strain SAB11 in iron-restricted minimal medium. Transcription of the sit operon is repressed under iron-rich growth conditions in a fur-dependent manner. Introduction of a sitBCD deletion into wild-type S. typhimurium resulted in no apparent growth defect in either nutrient-rich or minimal medium and no measurable virulence phenotype. These results further support the existence of redundant iron uptake systems in S. enterica.

Sequence comparisons have shown that it is a member of family III of the solute binding proteins. It is 89% identical to the collagen binding protein, Cnb, from Lactobacillus reuteri. Compared with the database of Escherichia coli proteins, BspA is most similar to the L-cystine binding protein FliY. To investigate the function of BspA, mutants depleted for BspA were generated by homologous recombination with a temperature-sensitive plasmid. These mutants were significantly impaired in their abilities to take up L-cystine. Uptake rates of L-glutamine L-histidine, and L-lysine, which are substrates for other binding proteins with similarity to BspA, were unaffected. Evidence was obtained that BspA is necessary for maximal resistance to oxidative stress. Specifically, inactivation of BspA causes defective growth in the presence of oxygen and sensitivity to paraquat. Measurements of sulfhydryl levels showed that incubation of L. fermentum BR11 with L-cystine resulted in increased levels of sulfhydryl groups both inside and outside the cell; however this was not the case with a BspA mutant. The role of BspA as an extracellular matrix protein adhesin was also addressed. L. fermentum BR11 does not bind to immobilized type I collagen or laminin above background levels but does bind immobilized fibronectin. Inactivation of BspA did not significantly affect fibronectin binding; therefore, we have not found evidence to support the notion that BspA is an extracellular matrix protein binding adhesin. As BspA is most probably not a lipoprotein, this report provides evidence that gram-positive bacterial solute binding proteins do not necessarily have to be anchored to the cytoplasmic membrane to function in solute uptake.

Such behaviour suggests that these insects should exhibit population dynamics consistent with the latent classification proposed by Price et al. (1990). While this empirical hypothesis is intuitively appealing it does not appear to incorporate current population dynamics theory. Berryman's ecodynamics (1992) offers the potential to describe a species' population dynamics which is grounded in a quantitative theoretical framework. The population ecology of Amorbus species from Australia is considered in relation to these hypotheses.

Exposure at the Hanford site occurred after massive releases of iodine-131. At the Hanford site, 60 cases of juvenile hypothyroidism were found, with 54 females and six males. The onset of the disease was associated strongly with the years of reported maximum super(131)I releases, which occurred between 1944 and 1949. In the Chernobyl area, rates of hypothyroidism were appreciably higher in Zhitomir and Gomel, somewhat higher in Mogilev and Bryansk, and lowest in Kiev. The extensive data are tabulated.

Results showed that fulvic acid appeared to generate reactive oxygen radicals that may interfere directly with cell membranes and result in lipid peroxidation. In rats fed normal diets and water coming from the impacted region, there was an increase in lipid peroxidation in blood and liver. The data suggested that fulvic acid could be incorporated into bone and cartilage of rats, which is the target tissue of Kashin-Beck disease, where selenium concentration is low.

All sampling sites were located in residential neighborhoods within 2500 m of metal smelters or a metal refinery. Results showed that, in all three cities, heavy-metal levels exceeded maximum allowable levels determined by EPA. In Terreon and Chihuahua, levels of contamination for all three metals were related inversely to distance from the industrial sites. Contamination appeared to be significantly higher for all metals around the active smelter than around the inactive smelter and the metal refinery.

The experimental protocol is detailed. Results showed that, of the four groups of compounds evaluated, only hydroxylated PCBs bound to human thyroid receptor, with affinities ranging 3090 mu M. These compounds exhibited 1000-fold greater affinities for transthyretin than for thyroid receptor, making them competitors for the natural ligand, thyroxine. These findings suggest that disruption of thyroid hormone transport may be one of the mechanisms by which organochlorine compounds alter thyroid homeostasis. Few of the compounds competed for thyroid-binding globulin.

The bioassay protocol is described. The chemicals examined included bisphenol A, octylphenol, di-n-butyl phthalate, o,p'-DDT, and methoxychlor. Results showed that progesterone-induced maturation of X. laevis oocytes was not sensitive to estrogens, but was potently inhibited by methoxychlor. The data suggested that methoxychlor targeted events occurring in the first 2 h after exposure to progesterone, as no maturational signaling initiated in the first 2 h of incubation was blocked by subsequent exposure to methoxychlor.

The most promising field of research involves genetic engineering to produce a variety of substances, such as industrial chemicals, drugs, and ingredients used in consumer products. Promising research fronts in this area are described at the University of Kentucky, North Carolina State University, the University of Central Florida, and at CropTech Development Corporation. Besides actual new product development, other considerations are also being addressed, including production costs of tobacco compared to other crops and efforts to secure additional research funding.

Using data from the International Clearinghouse for Birth Defects Monitoring Systems, worldwide trends in these defects were examined. For hypospadias, an upward trend was discerned beginning in 1970 in the US, Scandinavia, and Japan, but significant inter-country variation in rates was observed. Rates tended to level off after 1985. There was no indication of a generalized increase in cryptorchidism rates over time.

Results showed a median daily intake of 7.4 mu g Pb/kg/d for the study group, which was relatively low. For the pregnant migrants, there was no significant difference in the mean Pb-206/Pb-204 ratio in blood and diet over the entire period of pregnancy and six months postpartum. However, during the postpartum period, the mean ratio for blood was significantly higher than that for diet. For the nonpregnant migrant controls, there was no significant difference in super(206)Pb/ super(204)Pb ratio over time for blood and diet. Similar results were found for the pregnant Australian subjects. These changes over time during and after pregnancy could not be explained by dietary Pb, which was consistent with earlier findings that the skeleton was the major contributor to blood Pb during pregnancy and postpartum.

Invertebrates form a central component of these ecosystems. We conducted a stratified survey of 69 sites on sub-Antarctic Macquarie Island and used logistic regression models to describe the distribution of 14 abundant invertebrate species. We also developed a statistical model of windspeed based on topography. The distributions of individual species were described by different combinations of aspect, altitude and vegetation type. Ordination of sites based on species composition showed strong effects of altitude and vegetation on invertebrate assemblages. The species distribution models provide a tool for detecting, monitoring and predicting effects of climate change and alien species on biota and ecosystem processes.

United States Senate, One Hundred Sixth Congress, First Session. AN - 62398566; ED441930 AB - The Senate Committee on Health, Education, Labor, and Pensions met to consider the largest program within the Elementary and Secondary Education Act, Title I, Helping Disadvantaged Children Meet High Standards. At this hearing, how Title I funds are spent, who they serve, and whether student performance is improving were topics discussed. After introductory remarks by Senators James M. Jeffords (Vermont), Christopher J. Dodd (Connecticut), Patty Murray (Washington), and Susan M. Collins (Maine), a panel of experts testified about the funding and impact of Title I. Wayne Riddle of the Congressional Research Service gave an overview of Title I. David Baroudi, Vermont's Title I director, discussed the important role of Title I and the need to integrate it with other education programs. Lula Ford, the Title I director for the Chicago, Illinois, schools discussed the way Title I related to overall reform efforts. William Taylor of the Citizen's Commission on Civil Rights suggested needed changes for the upcoming reauthorization of Title I. The final witness, Terry Bergeson, chief state school officer of Washington, presented her perspective on Title 1 and its relationship to other state and federal education programs. Prepared statements of these witnesses follow their testimony.

Population A had a very high overall level of chlamydial infection (85%) with significantly more of these infections being due to C. pecorum (73%) compared to C. pneumoniae (24%). The second population had a much lower prevalence of infection (10%) with equal levels of both species. An important finding of this study was that, while five of 24 C. pecorum-infected koalas had clinical signs of the disease (both ocular and urogenital sites), none out of seven C. pneumoniae-infected koalas had signs of clinical disease. This suggests that C. pecorum may be the more pathogenic of the two chlamydial species infecting this host. The level of infection (assessed by intensity of the specific hybridisation signal) also differed between chlamydial species, with C. pecorum infections ranging from low to high grade whereas C. pneumoniae infections were always low grade. When the age of infected koalas was examined, 58% of young, sexually immature koalas were found to have C. pecorum infections, increasing to 100% of koalas in the older age groups. This suggests that, in this population at least, young koalas are readily infected with C. pecorum from their mothers. While the infection levels with C. pneumoniae were too low to be statistically significant, again, sexually immature koalas were found to be infected. The recent separation of chlamydial infections in koalas into two species is beginning to indicate different epizootiologies for koala C. pecorum compared to koala C. pneumoniae..

Overexpression in plants alters the composition of phospholipids. AN - 69607170; 10066765 AB - We describe the cloning of a wheat cDNA (TaPSS1) that encodes a phosphatidylserine synthase (PSS) and provides the first strong evidence for the existence of this enzyme in a higher eukaryotic cell. The cDNA was isolated on its ability to confer increased resistance to aluminum toxicity when expressed in yeast. The sequence of the predicted protein encoded by TaPSS1 shows homology to PSS from both yeast and bacteria but is distinct from the animal PSS enzymes that catalyze base-exchange reactions. In wheat, Southern blot analysis identified the presence of a small family of genes that cross-hybridized to TaPSS1, and Northern blots showed that aluminum induced TaPSS1 expression in root apices. Expression of TaPSS1 complemented the yeast cho1 mutant that lacks PSS activity and altered the phospholipid composition of wild type yeast, with the most marked effect being increased abundance of phosphatidylserine (PS). Arabidopsis thaliana leaves overexpressing TaPSS1 showed a marked enhancement in PSS activity, which was associated with increased biosynthesis of PS at the expense of both phosphatidylinositol and phosphatidylglycerol. Unlike mammalian cells where PS accumulation is tightly regulated even when the capacity for PS biosynthesis is increased, plant cells accumulated large amounts of PS when TaPSS1 was overexpressed. High levels of TaPSS1 expression in Arabidopsis and tobacco (Nicotiana tabacum) led to the appearance of necrotic lesions on leaves, which may have resulted from the excessive accumulation of PS. The cloning of TaPSS1 now provides evidence that the yeast pathway for PS synthesis exists in some plant tissues and provides a tool for understanding the pathways of phospholipid biosynthesis and their regulation in plants.

A series of large-scale (300 m super(2)) rainfall simulator experiments on disturbed forest hillslopes, incorporating both snig track (skid trail) and general harvesting areas (GHA), examined runoff generation and redistribution during three sequential simulated storms on 13 sites. The simulated storms represented 30-min rainfall events with recurrence intervals of 2, 10, and 100 y respectively. The 13 sites were selected to represent dominant soil types and ages since disturbance. The snig tracks and GHA are characterised by significantly different soil hydraulic and vegetation properties as reflected in the nature and magnitude of runoff production. Infiltration-excess runoff dominated the snig track areas, while on recently disturbed GHA, runoff was distinctly patchy because of the high degree of spatial variability in saturated hydraulic conductivity (K sub(s)) and degrees of disturbance. Surface runoff from recently constructed snig tracks was an order of magnitude higher than the neighbouring GHA. Relative differences in runoff production between the two areas declined during extreme rainfall events. Infiltration tests also indicated that a change in the processes and rates of runoff persists for at least 5 y after disturbance. The practice of redistributing concentrated snig track runoff at cross banks was most effective for small storms. However, during more extreme events, the volume of snig track runoff increased and flow velocities and transport distances increased as the hillslope became increasingly saturated. The varying ability of the GHA to generate runoff and absorb concentrated flow from the snig track is likely to be critical in predicting both the initial hydrologic response and the recovery of a small catchment from forest disturbance.

Although some children recover some of these abilities, many children with Landau-Kleffner syndrome have significant language impairments that persist. Multiple subpial transection is a surgical technique that has been proposed as an appropriate treatment for Landau-Kleffner syndrome in that it is designed to eliminate the capacity of cortical tissue to generate seizures or subclinical epileptiform activity, while preserving the cortical functions subserved by that tissue. Reported here are the speech & language outcomes of children (N = 14) who underwent multiple subpial transection for treatment of Landau-Kleffner syndrome. Eleven children demonstrated significant postoperative improvement on measures of receptive or expressive vocabulary. Results indicate that early diagnosis & treatment optimize outcome & that gains in language function are most likely to be seen years, rather than months, after surgery. Since an appropriate control group was not available & the best predictor of postoperative improvements in language function was that of length of time since surgery, these data might best be used as a benchmark against other Landau-Kleffner syndrome outcome studies. 3 Tables, 21 References.

AN - 759313546; 13662589 AB - This paper is a reflection on the workshop Agriculture as a Mimic of Natural Systems. It analyses what is essential for protecting agricultural land from degradation, including enabling features of the social context. It looks at how natural systems maintain a stable landscape, and explores ways in which pertinent features of natural systems can be copied in agriculture to help solve particular problems of land degradation, such as: erosion; hydrologic instability and the often associated secondary salinity; and chemical imbalances, such as those leading to excessive acidity. The conservative practices that many farmers have recently adopted are in several respects based on attributes of natural systems, but the mosaic nature of land is one important aspect that has not yet strongly influenced practices, which are often too strongly tied to cadastral boundaries.

Statistical Analysis Report. AN - 62494234; ED431051 AB - This report, 10th in a series, presents data for 1997 on high school dropout rates, and examines high school completion and graduation rates. The report is based on the best and most current national data available, using data from the Current Population Survey of the Bureau of the Census. Data show that about 5 out of every 100 young adults enrolled in high school in 1996 left school before October of 1997 without successfully completing a high school program. This estimate (the "event" dropout rate) of 4.6% was similar to those reported over the last 10 years, but lower than that of the early 1970s. Hispanic students were more likely than white and black students to leave school short of completing a high school program. In 1997, 9.5% of Hispanics were event dropouts, compared with 3.6% of Whites and 5.0% of Blacks. Young adults from families with incomes in the lowest 20% of all family incomes were nearly seven times as likely to dropout as were their peers in the top 20% of income distribution. Status dropout rates represent the proportion of young adults aged 16 to 24 years who are out of school and have not earned a high school credential. In October 1997, 11% of the young adults in the United States were in this situation. Hispanic young adults have higher status dropout rates than either Whites or Blacks. In addition, data show that, in 1997, about 86% of all 18-through 24-year-olds not enrolled in school had completed high school or an equivalent credential.

AN - 62489616; ED428134 AB - This report contributes to the comprehensive evaluation of the Common Core of Data (CCD) program by providing an analysis of CCD definitions in order to identify potential classification problems. At the time of the evaluation, the CCD program consisted of four surveys. The focus of this evaluation is on the "Public Elementary/Secondary Education Agency Survey." The evaluation process was initiated by researching state statutes and administrative codes to determine the powers, governance, and services provided by agencies in each state. A detailed analysis of CCD definitions reveals that these definitions are generally inadequate. Many are neither exhaustive nor inclusive. The inadequacy and misinterpretation of these definitions leads to unreliable and invalid data. CCD definitions often do not draw a clear distinction between school and agency surveys. The definitions should be revised to be flexible and exhaustive, with clear documentation and explanation provided for instances in which individual arrangements in states differ from conventional approaches. All education surveys that use CCD definitions as their sampling frame should be coordinated. Changes are especially needed in the areas of enrollment and geographic coding. (Contains two tables.)

AN - 62484066; ED428451 AB - This volume reports on the Case Study Project, an initiative that evaluates the experiences of math and science teachers across the United States and includes levels of schooling and achievement levels. The report focuses on typical public schools in the United States at three levels: elementary, junior high, and senior high with the intent of creating a composite profile of typical schools. The volume is divided into five chapters: "Rationale for the Study,""The Development and Implementation of Education Standards in the United States,""Individual Differences and the United States Education System,""The Role of School in United States Adolescents' Lives," and "Teachers and the Teaching Profession in the United States." Results show that the typical school had adopted curriculum standards or guidelines proposed by state departments of education, rather than by a national body. One exception to this was the influential set of national guidelines developed by the National Council of Teachers of Mathematics. Despite the general interest in standards, the choices made by parents, teachers, and students reflected many values, of which the desire for independence was one of the strongest. Students who were surveyed exhibited high optimism, especially those students from middle- class families.

Lagoon evolution and phosphorus dynamics AN - 20710227; 4626667 AB - Anthropogenic changes detected in the sediment of a shallow ( similar to 1.6 m) billabong (Horseshoe Lagoon) are the result of a Sewage Treatment Plant (STP) connection in 1958 and catchment urbanization around 1974. Nutrient-rich water caused the collapse of macrophyte populations, algal blooms became common, and urbanization increased sediment deposition ( similar to 1 cm year super(-1)). Changes in P retention were investigated by using dated cores, pore-water element profiles, and water quality records. The lagoon is the last of three STP holding ponds. Ponds 1 and 2 were sand-mining pits; they receive no sediment input and have negligible P adsorption. The Fe:P ratios in sediments from three Australian rivers have a common slope and this relationship was used to examine Fe:P ratios in the anoxic bottom sediments of the lagoon. A potential for effluent P adsorption developed in the lagoon through Fe mobilization and enrichment in the upper sediments and a strong clay-Fe-P association. The mean long-term P adsorption in the lagoon (35 plus or minus 18%) was the result of maintaining clay input to an oxic waterbody.

Two types of voyages were undertaken: five World Ocean Circulation Experiment (WOCE) cruises along longitude 140 degree E; and two Antarctic and Heard Island exploratory fishing / re-supply voyages between Hobart, Heard Island and the Australian Antarctic Territory. Observations were carried out to describe the distribution of seabirds, including penguins, at sea. In this paper penguin distribution has been described, along with an analysis of environmental variables associated with the sightings, and an attempt was made to use these variables to predict penguin distribution. Ten species were observed: Emperor Aptenodytes forsteri, King A. patagonicus, Adelie Pygoscelis adeliae, Gentoo P. papua, Macaroni Eudyptes chrysolophus, Royal E. schlegeli, Rockhopper E. chrysocome, Snares Crested E. robustus, Fiordland Crested E. pachyrhychus and Little Eudyptula minor Penguins. The sightings of Snares Crested and Fiordland Crested Penguins were unique in the sector covered. Juvenile and adult Emperor, Adelie and Macaroni Penguins were found in different sectors of the Southern Ocean. Latitude, longitude, depth of water, salinity, sea surface temperature, ice cover and icebergs were recorded. Cluster analysis was used to predict penguin distribution, and compiled three groups. A discriminant function analysis revealed only moderate success in the allocation of species to these groups. This probably arose because: 1. the environmental variables measured were not good indicators of penguin distributions at sea; 2. the sightings of penguins were probably not always at foraging grounds, and penguins may have been en route to foraging zones when observed; 3. the patterns of penguin distribution are not predictable at the scale of analysis because they respond opportunistically to regions around their breeding sites; 4. penguins are not congregating at specific areas.

AN - 17466545; 4674845 AB - Fogg and Walsby's (1971) hypothesis that buoyancy regulation in cyanobacteria might be an adaptation to exploit the separation of light and nutrients has since become a paradigm. The evidence of its veracity is examined within observations of algal abundance and chlorophyll distributions in several Australian freshwater systems and is also reviewed from the literature. It is clear from both laboratory experiments and field measurements that filamentous genera such as Anabaena and colony-forming genera such as Microcystis are capable of changing their buoyancy within a diurnal cycle. However, evidence for population migration to exploit separation of light and nutrient availability is tenuous, with most field observations of the vertical distribution of phytoplankton populations showing no evidence of vertical migration to sufficient depth to reach nutrients in stratified systems. Instead, changes in the vertical distribution of phytoplankton suggest a response either to the dynamics of the surface mixed layer or to lateral advection. In natural systems, algal buoyancy appears to be dependent much more on light than on nutrients, this being consistent with the carbohydrate ballast mechanism. Physical mechanisms can provide sufficient replenishment of epilimnetic nutrients to explain the observed net growth rates of phytoplankton populations in situ.

Three to seven of the most prominent, congeneric shrub species in each of five communities were monitored following a total of six fires, and numbers of individuals prefire were compared with those over two to four winters postfire. The proportion of individuals in each species only sometimes reflected the proportion at an earlier time. At least one species differed from the rest for twenty-six of a total of twenty-seven demographic steps assessed. Initial seedlings/parent, which was largely a function of seeds available, and, to a lesser extent, level of germination, were the most important attributes in accounting for the recruitment patterns. There was a trend for the faster growing, drought avoiding species to increase at the expense of the others. In the most comprehensive study, life form (four nonsprouting Hakea spp. v. four resprouting Hakea spp.) was the best predictor of the recovery pattern. This was through its association with seed availability and level of germination and, to a lesser extent, drought survival (all higher for nonsprouters). Leaf type, as an indicator of drought tolerance, had inconsistent predictive power between studies. The least summer stressed species, in terms of survival and water relations, tended to have the largest seedlings derived from the largest seeds, but there were notable exceptions. Within each life form category, species behaviour varied widely, making most predictions of postfire community dynamics based on relative prefire numbers little more than conjectural. However, in only one of the three studies were the trends sufficiently clear to show that postfire densities would never mirror those prefire.

In central Port Phillip Bay, there was a rapidly mixed surface layer and two layers of different mixing rates at 2-20 cm and 21-45 cm depths. When the sediment profiles of excess super(210)Pb and super(228)Th were combined and diffusive mixing was assumed, the sediment accumulation rate in the 2-20 cm layer was constrained to be <0.15 cm year super(-1). The mixing coefficient in the 2-20 cm layer was 5.0 plus or minus 0.1 cm super(2) year super(-1). Hence, mixing rather than sedimentation governs the distribution of super(210)Pb and super(228)Th in the surficial 20 cm. Below 20 cm, the different mixing regime may be due to the dominance of deposit-feeders at these depths. Evidence for bioturbation to a depth of 50 cm was obtained from profiles of excess super(210)Pb and super(228)Ra deficiency. The mean residence time of particles in the central bay water column was 10 plus or minus 2 days (a normalized depositional particle flux of 0.16 plus or minus 0.02 g cm super(-2) year super(-1)). This flux is three times the upper estimate of the sediment accumulation rate, indicating that most of the suspended particulate matter in the water column is resuspended bottom sediment.

The integrated fluxes of biogenic N sub(2), ammonia, nitrate and nitrite showed that the stoichiometric relationship between organic C and N in the muddy sediments, occupying about 70% of the seafloor, was 5.7, this being similar to the Redfield ratio of 6.6. High denitrifying efficiencies (75-85%; denitrification rates similar to 1.3 mmol N sub(2) m super(-2) day super(-1)) at organic carbon loadings of similar to 15-25 mmol m super(-2) day super(-1) indicate that most N processed through the sediments was returned to the overlying waters as biologically (generally) unavailable N sub(2). At sites of high organic carbon loadings to the sediments (>100 mmol m super(-2) day super(-1)) denitrification rates and denitrifying efficiencies were near zero and most N is returned to the Bay waters as biologically available ammonium. In chambers 'spiked' with super(15)NO sub(3), denitrifyers used nitrate produced in the sediments in situ, rather than the exogenous nitrate in overlying waters. The sedimentary microbial processes of ammonification, nitrification and denitrification are therefore tightly coupled.

Model coupling was achieved via a particle tracking method, giving great flexibility in both geometry and time step for the transport model. This technique allowed ecological (water quality) modules to be included efficiently, so that long-term management scenarios could be adequately addressed. Validation of the hydrodynamic model was done primarily against observed sea-level and current meter data. For the transport model, comparisons were made with data on salinity in the bay observed over five years. Despite some disagreement between the hydrodynamic model and observations of longer-term (non-tidal) currents, the transport model provided good simulations of salinity throughout the bay. Transport-model flushing time for the bay was about 270 days (similar to estimates obtained from salinity and radionuclide measurements), varying with model geometry and with position inside the bay. As well as providing physical forcing for ecological simulations (described elsewhere in this issue), the models identified a systematic bias in the known freshwater budget for the bay.

Water samples were also collected to identify possible sources of faecal contamination. Bay sediments had total fatty acid concentrations between 4 and 183 mu g g super(-1) (dry weight) and total sterol concentrations between 0.6 and 39.2 mu g g super(-1). Creek sediments contained more sterols, ranging from 22.8-148 mu g g super(-1). These lipid distributions suggest that the bulk of the labile organic matter derives from marine microalgae, primarily diatoms. Coprostanol (5 beta -cholestan-3 beta -ol), a sterol often used as an indicator of faecal contamination, was also present. Concentrations ranged from <0.01-0.55 mu g g super(-1) in surface sediments, with values over 0.25 mu g g super(-1) and 5 beta -/5 alpha -C sub(27) stanol ratios greater than 0.4, indicative of sewage inputs. A clearer picture of distributions of sewage-derived organic matter was obtained when coprostanol was normalized to total organic matter rather than sediment dry weight. Areas showing higher coprostanol concentrations included those adjacent to the main sewage treatment plant and several low-volume drains and creeks, indicating localized problems of sewage contamination.

The developed model is able to reproduce effectively and simultaneously for all considered time scales the observed hysteresis in the relationship between chemical concentration in stream water and river discharge. Three types of catchment have been examined for long-term modelling: a local urban streamwater catchment, a transition urban-agricultural catchment and a large catchment with varied land use (urban, agricultural and protected forested areas). The long-period changes in model parameters and in water-quality variables are determined for each catchment.

The model simulates the cycling of N, P and Si in the water-column, epibenthos and sediments, and is driven by a physical transport model. The integrated model is forced by exchanges with Bass Strait and by nutrient inputs from the Western Treatment Plant, rivers, and the atmosphere. The model has been calibrated and tested by using data from process studies, flux measurements and spatial surveys at a range of scales. It provides a picture of nitrogen cycling through the water and sediments on bay-wide annual scales, which emphasizes the role of denitrification. It also reproduces well the observed spatial and temporal variation under varying nutrient load regimes, and provides insights into the factors controlling regional phytoplankton blooms, including the interaction of nitrogen and silica in the western bay. The model is used to investigate the bay's responses to changed nutrient loads, changes in sediment biogeochemistry, and marine pest invasion. The bay's assimilative capacity for nitrogen is largely controlled by its sediment denitrification capacity. If nitrogen loads approach the limits of this capacity, a rapid onset of eutrophication is predicted.

Such stages are seen as a potential mechanism for population persistence following environmental adversity. Laboratory incubation experiments were conducted on estuarine sediments. As a result, dormant eggs in Australian estuarine-endemic copepods are reported for the first time. Nauplii of the dominant estuarine-endemic calanoids Gippslandia estuarina and Sulcanus conflictus commonly hatched from the sediments. Manipulation of the salinity and temperature of experimental media indicated that temperature was the more important hatching trigger for S. conflictus, and that both high salinity and high temperature were important for G. estuarina. Results of the incubation experiments, including those of 'conversion' experiments (i.e. from freshwater to saline conditions or low temperature to high temperature), help to elucidate the type of dormancy characteristic of each species; it appears that S. conflictus may have diapause eggs and G. estuarina may have quiescent eggs, although this is yet to be confirmed. Other estuarine fauna developed from the mud during the incubation experiments, most notably the harpacticoids Onychocamptus chathamensis, an ectinosomatid and Schizopera sp., and the medusa Australomedusa baylii. Ecological and evolutionary consequences of dormancy in these estuarine-endemic zooplankton are briefly discussed.

In order to determine their composition and formation, these laminae were studied using a combination of X- ray analysis, scanning electron microscopy, X-ray diffraction and vibrational spectrometry. Results indicated that the laminae were composed of clay originating from the adjacent Gordon River estuary. The clay was also found as part of the general sediment matrix of the core. The evidence indicates that the laminae are formed during incursions of brackish water from the adjacent Gordon River estuary into Lake Fidler which cause the flocculation of clay minerals in the water column. These clay minerals then sink rapidly to the sediments to form laminae. Although the formation of these laminae pre-dates meromixis, their mode of formation corroborates the theory that meromixis is maintained ectogenically by periodic inflows of brackish water replenishing monimolimnetic salts.

In this work, we observed cellular localization of the SeqA-Gfp fusion in living cells. SeqA-Gfp was localized to a discrete focus or foci in wild-type and seqA null mutant cells, but the fusion was dispersed in the whole cell in dam null mutant cells lacking Dam methyltransferase. These results were consistent with the previous description of the localization of SeqA by immunofluorescence microscopy. Time-lapse experiments revealed that duplicated SeqA-Gfp foci migrated rapidly in opposite directions. Flow cytometry demonstrated that the fusion restored synchronous replication of chromosomal DNA from multiple origins in seqA null mutant cells, indicating that SeqA-Gfp is biologically active. Immunoprecipitation of the fusion from cell extracts using anti-Gfp antibody indicated that the fusion was assembled with the wild-type SeqA protein.

The model incorporates a simple growth function determined by the availabilities of silica and light, and by temperature. It also includes losses due to sinking and downstream advection. The model is tested against weekly measurements for the period 1981-1990, at three sites separated by 1100 km. The seasonal cycle of Aulacoseira concentrations along the river is well represented by the model. During times of high flow, the concentrations of Aulacoseira remain fairly uniform along the river as the diatoms have insufficient time to grow before being advected downstream.

This case-control study was, therefore, carried out to find out the associations between several social and environmental variables and deaths of children due to infectious diseases such as those leading to diarrhoea, acute respiratory infection, measles and other diseases. Six hundred and twenty-five deaths (cases) and an equal number of matched living children (controls) aged 1-59 months, were studied in rural Matlab. An analysis of crude and adjusted odds ratio showed differential associations. Sources of drinking water, amount of stored water, conditions of latrines, number of persons sleeping with the child and the type of cooking site were statistically significantly associated with deaths due to infectious diseases after controlling for breast feeding, immunization, and the family size. Significant associations were also observed between: (i) the sources of drinking water and deaths due to ARI, and (ii) conditions of latrines and deaths due to diarrhoeal diseases, after controlling for the confounding variables. Several other environmental factors also showed associations with these various death groups, but they were not statistically significant. The size of the samples in death groups (small) and the prevalence of more or less homogeneous environmental health conditions probably diminished the magnitude of the effects. The results of the study reconfirm the importance of environmental health intervention in child survival, irrespective of breast-feeding, immunization, and selected social variables.

Aeromonas caviae was the most prevalent species, accounting for 32% (129/405) of all isolates. Eighty-three per cent of children with Aeromonas-associated diarrhoea were younger than 3 years. The majority of the children had acute onset of vomiting and watery diarrhoea resulting in mild to moderate dehydration. Fever, non-watery diarrhoea, age less than 3 years, and diarrhoea of 7-14 days duration were found to be significantly associated with Aeromonas diarrhoea compared with Vibrio cholerae O1 infection after adjusting for confounders. Aeromonas-associated diarrhoea was most common from March to May (during the peak of the hot and humid season), and September to October, similar to Vibrio cholerae O1. Our results indicate that Aeromonas infection is common in young children presenting with diarrhoea in Bangladesh.

In 1966/1967 Gould (1980) studied operational aspects of hunting-gathering in desert regions of northwestern Australia and recorded sufficient quantitative and species-specific data to allow definition of the diet over 5 months. By 1966, many Aboriginal people in that region had been displaced from their hunting grounds and were living in camps on cattle stations or in missions. Aboriginal diet on cattle stations in the north-west was studied in 1951 (Commonwealth Department of Health) and shown to consist chiefly of fresh meat, wheaten flour, and sugar with small amounts of vegetables and dairy products. With the granting of citizenship in 1967, most Aborigines were dismissed from cattle stations and were moved first to town camps and later formed remote Aboriginal communities. Studies in the 1980s showed that the self-selected diet in such communities reflected the station diet to a greater extent than the traditional diet. Quantitative presentation of the above three diets, in terms both of foods and of major nutrients, show that many of the dietary inadequacies of the station diet identified in 1951 still persisted in self-selected Aboriginal diets in the 1980s. A comparison of the three diets with a modern recommended diet supports the nutritional adequacy of the hunter-gatherer diet. Traditional cultural values assigned to food preferences continued to influence food choices in all three diets.

The paper highlights the potential of data loggers to gain insights into the foraging distribution and behaviour of seabirds. Archival tags recording light and temperature were placed on non-breeding Wandering Albatrosses Diomedea exulans from South Georgia and the Crozet Islands. Estimates of position for a Wandering Albatross from the Crozet Islands indicated an extensive journey from southern Africa across the Indian Ocean to south-eastern Australia and east of New Zealand. A Wandering Albatross from South Georgia apparently moved east across the Atlantic Ocean, while another moved west to longitudes approximating the Patagonian Shelf. These areas correspond to previously known movement patterns to areas of high activity by Southern Ocean longline fishing fleets. Albatrosses are an important by-catch of these fisheries, and knowledge of the spatial and temporal distributions of these threatened species will assist assessments of interactions and risk.

Vibrio cholerae O139 strains possess a thin capsule and have been found to be partially serum resistant in a previous study. In the present study, compared to a standard capsulated Klebsiella pneumoniae strain, which showed total resistance to killing by phagocytosis, V. cholerae O139 strains were shown to be only partially resistant, with most strains showing <40% survival. These findings may explain the relative rarity of V. cholerae O139 bacteremia in cholera caused by this organism.

Results showed that average concentrations for PM sub(10), PM sub(2.5), ammonium, and nitrate were similar during the summer among sites and indoor source categories. This indicated a strong regional nature to the summer aerosol, such that an ambient regional sampling site would be a reasonable predictor of fine particle concentrations measured outside homes. During the winter, PM sub(10) and PM sub(2.5) levels were higher in homes with kerosene heaters, while sulfate concentrations outdoors were higher than in homes without a kerosene heater and were lower than levels in homes with a kerosene heater. Unlike the summer data, most correlations were not significant for the winter data. However, use of a kerosene heater during the winter resulted in a substantial increase in indoor concentrations of PM sub(2.5), sulfate, and possibly H super(+). The extensive concentration data are tabulated.

Results showed that, for males, the urinary excretion of 8-OHdG was not related to any of the radiation variables. In females, however, both Rn and gamma -radiation exposures were related significantly to concentrations of urinary 8-OHdG. Multivariate analysis revealed that the role of gamma -radiation was more important than that of Rn.

The embryos were analyzed subsequently for organochlorine contaminant residues, plasma corticosterone concentrations, and intermediary metabolic enzyme activities. Results showed that the total PCB fraction accounted for more than 60% of the total residues, while the PCDD/F fraction accounted for less than 1%. Of the chlorinated hydrocarbons, p,p'-DDE accounted for more than 77% of the fraction. Significant negative correlations were observed when individual yolk sac PCDDs/PCDFs, total PCBs, non-ortho PCBs, and toxic equivalents were regressed against basal plasma corticosterone levels, but no such significant correlation was found for the chlorinated hydrocarbon concentrations. A significant negative correlation was found when individual yolk sac PCDD/PCDF concentrations were regressed against malic enzyme activities for the same individual, while a possibly significant correlation was found between individual yolk sac PCDD/PCDF concentrations and kidney cytosolic phosphoenolpyruvate carboxykinase activity.

Results showed a significantly higher level of bulky carcinogenDNA adducts in the group classified as the high-exposure group, whereas the levels of PAHalbumin adduct and markers of oxidative stress in hemoglobin were significantly higher in the suburban/semirural group. Levels of malondialdehyde were significantly higher in bus drivers than in postal workers. A statistically significant correlation was observed between the content of total monocytes and the bulky carcinogenDNA adduct level. A negative association was observed between carcinogenDNA adduct level and the level of 2-amino-apidic semialdehyde in hemoglobin in the bus-driver groups.

No differences were found in the gonadosomatic index between sites. Females exhibited no difference in hepatosomatic index, but males from the contaminated site exhibited a larger hepatosomatic index than males from the reference site. Plasma concentrations of the steroid hormones, estradiol and testosterone, did not differ between sites for females, but males from the contaminated site had significantly lower circulating levels of testosterone than males from the reference site. No differences for either sex were found in terms of the presence of vitellogenin between sites.

At the end of the exposure, the anchorage-independent growth of the cells was examined by counting the number of colonies larger than 60 mu m. Results showed that exposure to the magnetic fields did not increase anchorage-independent proliferation of the cells. The cells displayed a dose-dependent response to increasing concentrations of TPA, but co-exposure to both TPA and the magnetic fields did not result in any differences in transformation frequency.

Synthetic data sets, which are detailed, were used. The results suggest that modeling bias will probably occur when regression models are used in an effort to identify the causes of a health outcome in an uncontrolled environment, which can lead to seriously erroneous conclusions. The results further suggest that models that use only one or two air-quality variables will most likely be unreliable.

One such pathway is the Sonic hedgehog pathway and its transcriptional mediator, GLI, which is critical to several developmental events in a wide range of organisms. Each component of this pathway is described, including the 150-dK GLI protein and its DNA binding sequences.

Results are presented from a study in which this cell line was used to evaluate the estrogenic potential of four synthetic pyrethoid compounds: sumithrin, fenvalerate, d-trans allethrin, and permethrin. The compounds were assayed for their ability to induce pS2 gene expression. Results showed that sumithrin was able to induce both pS2 gene expression and MCF-7 cell proliferation at nanomolar concentrations. Fenvalerate and d-trans allethrin were also able to disrupt estrogen function, whereas permethrin did not affect estrogen regulation.

Cancer-mortality data were summarized for 34 cancer sites by 5-yr age groups, and a 1990 state survey was used to glean detailed information on crop production, acreage, and pesticide use by county cluster. The identified 25 county clusters were combined into four regions based on specific crop production. Results showed that overall mortality from all cancers was decreased significantly in the three agricultural regions compared to the urban/forested region. However, increased age-standardized mortality-rate ratios were observed for lip, prostate, thyroid, and bone cancers in men living in specific agricultural regions. Increased age-standardized mortality-rate ratios were observed for nasopharynx, eye, and non-Hodgkin's lymphoma for women living in specific agricultural regions. Mortality from cancer of the trachea, bronchus, or lung was significantly decreased in the agricultural regions compared to the urban/forested region. Decreased mortality in men in the agricultural areas was also noted for cancer of the esophagus, large intestine, liver, gall bladder, pancreas, kidney, and ureter, while decreased mortality in women living in the agricultural areas was noted for cancer of the esophagus, pancreas, breast, ovary, and fallopian tube.

It is believed that deep-rooted perennial plants in these areas are able to reduce recharge and use shallow groundwater, thus controlling groundwater levels. Lysimeters represent the best experimental technique for investigating capillary upflow from shallow water tables and the associated processes of salt accumulation, plant water use, and growth response. Techniques involving stable isotopes of water help determine the components of upflow due to vegetation. When combined with models that stimulate salt and water movement in the soil zone and the plant water use and growth, we can thoroughly test our understanding of salinity processes and the ability of plants to control water tables. Results from WAVES simulations of plant growth, evapotranspiration, groundwater uptake, salt accumulation, and the impacts on lucerne growth are compared against measurements made in lysimeters at Griffith, NSW, Australia. With minimal calibration, WAVES was able to reproduce both the daily and seasonal variation in evapotranspiration, upward flux from the groundwater table, plant growth in terms of leaf area development, soil water profiles, soil water salinity, and root water extraction patterns. There was a decline of 36% in transpiration, 42% in leaf area growth, and 67% in upward flux after the salinity of the water table increased from 0.1 to 16dS/m. Although the upward flux of water was large, lucerne used little of it (< 20%), preferring 'fresher' rainfall and irrigation water near the surface. Given the tests presented in this work, we think WAVES is applicable to irrigated agricultural systems.

AN - 69582643; 9927753 AB - Specific recognition of a region of duplex DNA by triplex-forming oligonucleotides (TFOs) provides an attractive strategy for genetic manipulation. Based on this, we have investigated the ability of the triplex-directed approach to induce mutations at a chromosomal locus in living cells. A mouse fibroblast cell line was constructed containing multiple chromosomal copies of the lambdasupFG1 vector carrying the supFG1 mutation-reporter gene. Cells were treated with specific (psoAG30) or control (psoSCR30) psoralen-conjugated TFOs in the presence and absence of UVA irradiation. The results demonstrated a 6- to 10-fold induction of supFG1 mutations in the psoAG30-treated cells as compared with psoSCR30-treated or untreated control cells. Interestingly, UVA irradiation had no effect onthe mutation frequencies induced by the psoralen-conjugated TFOs, suggesting a triplex-mediated but photoproduct-independent process of mutagenesis. Sequencing data were consistent with this finding since the expected T.A-->A.T transversions at the predicted psoralen crosslinking site were not detected. However, insertions and deletions were detected within the triplex binding site, indicating a TFO-specific induction of mutagenesis. This result demonstrates the ability of triplex-forming oligonucleotides to influence mutation frequencies at a specific site in a mammalian chromosome.

Hydrogeologic and geochemical theories for ore genesis are explored in this paper with mathematical models that allow for complex permeability fields in two or three dimensions, hydrothermal flows in fault systems, and coupled effects of geochemical reactions. The hydrogeologic framework of carbonate-hosted ores is analyzed with the aim of developing a quantitative understanding of the necessary and sufficient processes required to form large ore deposits. Numerical simulations of basin-scale hydrodynamics and of deposit-scale reactive flow are presented to demonstrate the processes controlling low-temperature Pb-Zn ore genesis in two world-class ore districts, in southeast Missouri, USA, and central Ireland. The numerical models presented here provide a theoretical basis for the following observations: (1) topography-driven brine migration was the most effective mechanism for forming the large ore districts of the Mississippi Valley, such as the Viburnum Trend of southeast Missouri, during the uplift of the Appalachian-Ouachita mountain belt in late Paleozoic time; (2) three-dimensional flow fields were created by a dolomite facies of the Viburnum Trend, which acted as a giant lens for focusing metal and heat in southeast Missouri to produce the largest known concentration of lead in the Earth's crust; (3) ore-mineralization patterns were controlled locally by basement relief, permeability structure, and sandstone pinchouts, because of their effects on cooling and fluid-flow rates along the Viburnum Trend; (4) both density-driven and topography-driven fluid flow were important for ore genesis in the Irish midlands, where brines moved northward away from the Variscan orogen, leaked into the Hercynian basement, and discharged along normal faults up into the sedimentary cover; and (5) mixed convection within northeast-southwest fault planes elevated heat flow and flow rates that fed ore deposition by fluid mixing, in some cases near the Carboniferous seafloor in Ireland.Original Abstract: Les depots de minerai de plomb-zinc dans les carbonates de la region de la vallee du Mississippi en Amerique du Nord et dans les comtes du centre de l'Irlande fournissent de bons exemples de lieux ou, a des epoques geologiques passees, les mouvements d'eau souterraine ont controle la formation de minerai en profondeur dans des bassins sedimentaires. Dans ce papier, les theories hydrogeologiques et geochimiques de la formation de minerais sont examinees au moyen de modeles mathematiques qui prennent en compte des champs de permeabilite complexes en deux et en trois dimensions, des ecoulements hydrothermaux dans des systemes de failles et les effets couples de reactions geochimiques. Le cadre hydrogeologique des minerais dans les formations carbonatees est analyse dans le but de proposer une comprehension quantitative des processus necessaires et suffisants requis pour former des depots de minerais importants. Des simulations numeriques de l'hydrodynamique a l'echelle du bassin et de l'ecoulement reactif a l'echelle du depot sont presentes afin de montrer les processus controlant la genese du minerai Pb-Zn a basse temperature dans deux districts miniers de reference mondiale, dans le sud-est du Missouri et en Irlande centrale. Les modeles numeriques presentes ici donnent une base theorique aux observations suivantes: 1) la migration de saumure pilotee par la topographie a ete le mecanisme le plus evident pour la mise en place des vastes gisements de la vallee du Mississipi, tels que le Viburnum Trend dans le sud-est du Missouri, au cours de la surrection de la chaine de l'Appalache-Ouachita au Paleozoieque terminal; 2) des champs d'ecoulements tridimensionnels ont ete crees par un facies dolomitique du Viburnum Trend, qui se comporte comme une lentille gigantesque concentrant le metal et la chaleur dans le sud-est du Missouri pour produire la plus vaste concentration connue de plomb dans la croute terrestre; 3) l'organisation des mineralisations metalliferes a ete localement controlee par le relief du substratum, la structure de la permeabilite et le biseautage des gres, a cause de leurs effets sur le refroidissement et sur les flux de fluide le long de Viburnum Trend; 4) les ecoulements de fluides commandes a la fois par la densite et par la topographie ont ete importants dans la genese du minerai dans les comtes du centre de l'Irlande, ou des saumures se sont ecoulees vers le nord a partir de la chaine varisque, ont penetre dans le substratum hercynien et se sont ecoulees le long de failles normales jusque dans la couverture sedimentaire; et 5) la convection de melanges dans des plans de failles NE-SW a eleve les flux thermique et hydrique qui ont alimente la formation de minerai par melange de fluides, dans certains cas a proximite du fond marin au Carbonifere en Irlande.

AN - 69599180; 10048027 AB - The suppressor mutation, named sfhC21, that allows Escherichia coli ftsH null mutant cells to survive was found to be an allele of fabZ encoding R-3-hydroxyacyl-ACP dehydrase, involved in a key step of fatty acid biosynthesis, and appears to upregulate the dehydrase. The ftsH1(Ts) mutation increased the amount of lipopolysaccharide at 42 degrees C. This was accompanied by a dramatic increase in the amount of UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase [the IpxC (envA) gene product] involved in the committed step of lipid A biosynthesis. Pulse-chase experiments and in vitro assays with purified components showed that FtsH, the AAA-type membrane-bound metalloprotease, degrades the deacetylase. Genetic evidence also indicated that the FtsH protease activity for the deacetylase might be affected when acyl-ACP pools were altered. The biosynthesis of phospholipids and the lipid A moiety of lipopolysaccharide, both of which derive their fatty acyl chains from the same R-3-hydroxyacyl-ACP pool, is regulated by FtsH.

Postsecondary Education Descriptive Analysis Reports. AN - 62490036; ED428123 AB - This report uses postsecondary transcript data for members of the High School and Beyond Sophomore Cohort (students who were sophomores in 1980) to examine progress toward the Bachelor's degree among high school graduates who expected at least a Bachelor's degree, first enrolled at a 4-year institution, and had completed at least 10 semester credits by September 1993. On average, this group, which accounted for 59% of 1980 high school sophomores who had attended a 4-year institution by September 1980, completed about 27 semester hours in their first year. Students enrolled in private, not-for-profit institutions were more likely to complete at least 30 credits. Students' academic preparation and test scores were related to the number of credits they completed in the first year, as was their academic performance in the first year. The number of years students took to cross certain credit thresholds can be used to infer the minimum number of years a student would need to complete a 120- credit Bachelor's degree. Three of four students in the analysis completed a Bachelor's degree, and completion of the degree was more likely for students with higher grade point averages. Other factors related to credit completion are identified. Three appendixes contain reference tables, a glossary, and technical notes and comments on methodology. (Contains 13 tables and 5 figures.)

AN - 21350699; 7718543 AB - Geographic modeling of individual exposures using air pollution modeling techniques can help in both the design of environmental epidemiologic studies and in the assignment of measures that delineate regions that receive the highest exposure in space and time. Geographic modeling can help in the interpretation of environmental sampling data associated with airborne concentration or deposition, and can act as a sophisticated interpolator for such data, allowing values to be assigned to locations between points where the data have actually been collected. Recent advances allow for quantification of the uncertainty in a geographic model and the resulting impact on estimates of association, variability, and study power. In this paper we present the terminology and methodology of geographic modeling, describe applications to date in the field of epidemiology, and evaluate the potential of this relatively new tool.

AN - 21260222; 11702192 AB - The disparity between the rates of breast cancer in industrialized and less-industrialized regions has led to many hypotheses, including the theory that exposure to light-at-night and/or electromagnetic fields (EMF) may suppress melatonin and that reduced melatonin may increase the risk of breast cancer. In this comprehensive review we consider strengths and weaknesses of more than 35 residential and occupational epidemiologic studies that investigated the association between EMF and breast cancer. Although most of the epidemiologic data do not provide strong support for an association between EMF and breast cancer, because of the limited statistical power as well as the possibility of misclassification and bias present in much of the existing data, it is not possible to rule out a relationship between EMF and breast cancer. We make several specific recommendations for future studies carefully designed to test the melatonin-breast cancer and EMF-breast cancer hypotheses. Future study designs should have sufficient statistical power to detect small to moderate associations; include comprehensive exposure assessments that estimate residential and occupational exposures, including shift work; focus on a relevant time period; control for known breast cancer risks; and pay careful attention to menopausal and estrogen receptor status.

Twenty chemicals were selected to represent direct-acting estrogens, compounds with estrogenic metabolites, estrogenic antagonists, and a known cytotoxic agent. Also included in the test panel were 17I2-estradiol as a positive control and ethanol as solvent control. The test compounds were coded before distribution. Test methods included direct binding to the estrogen receptor (ER), proliferation of MCF-7 cells, transient reporter gene expression in MCF-7 cells, reporter gene expression in yeast strains stably transfected with the human ER and an estrogen-responsive reporter gene, and vitellogenin production in juvenile rainbow trout. 17I2-Estradiol, 17I--ethynyl estradiol, and diethylstilbestrol induced a strong estrogenic response in all test systems. Colchicine caused cytotoxicity only. Bisphenol A induced an estrogenic response in all assays. The results obtained for the remaining test compoundsatamoxifen, ICI 182.780, testosterone, bisphenol A dimethacrylate, 4-n-octylphenol, 4-n-nonylphenol, nonylphenol dodecylethoxylate, butylbenzylphthalate, dibutylphthalate, methoxychlor, o,pa2-DDT, p,pa2-DDE, endosulfan, chlomequat chloride, and ethanolavaried among the assays. The results demonstrate that careful standardization is necessary to obtain a reasonable degree of reproducibility. Also, similar methods vary in their sensitivity to estrogenic compounds. Thus, short-term tests are useful for screening purposes, but the methods must be further validated by additional interlaboratory and interassay comparisons to document the reliability of the methods.

AN - 21259041; 11704971 AB - The ability of cells to maintain genomic integrity is vital for cell survival and proliferation. Lack of fidelity in DNA replication and maintenance can result in deleterious mutations leading to cell death or, in multicellular organisms, cancer. The purpose of this review is to discuss the known signal transduction pathways that regulate cell cycle progression and the mechanisms cells employ to insure DNA stability in the face of genotoxic stress. In particular, we focus on mammalian cell cycle checkpoint functions, their role in maintaining DNA stability during the cell cycle following exposure to genotoxic agents, and the gene products that act in checkpoint function signal transduction cascades. Key transitions in the cell cycle are regulated by the activities of various protein kinase complexes composed of cyclin and cyclin-dependent kinase (Cdk) molecules. Surveillance control mechanisms that check to ensure proper completion of early events and cellular integrity before initiation of subsequent events in cell cycle progression are referred to as cell cycle checkpoints and can generate a transient delay that provides the cell more time to repair damage before progressing to the next phase of the cycle. A variety of cellular responses are elicited that function in checkpoint signaling to inhibit cyclin/Cdk activities. These responses include the p53-dependent and p53-independent induction of Cdk inhibitors and the p53-independent inhibitory phosphorylation of Cdk molecules themselves. Eliciting proper G1, S, and G2 checkpoint responses to double-strand DNA breaks requires the function of the Ataxia telangiectasia mutated gene product. Several human heritable cancer-prone syndromes known to alter DNA stability have been found to have defects in checkpoint surveillance pathways. Exposures to several common sources of genotoxic stress, including oxidative stress, ionizing radiation, UV radiation, and the genotoxic compound benzo[a]pyrene, elicit cell cycle checkpoint responses that show both similarities and differences in their molecular signaling.

AN - 21256954; 11703760 AB - In the adult nervous system, neurotransmitters mediate cellular communication within neuronal circuits. In developing tissues and primitive organisms, neurotransmitters subserve growth regulatory and morphogenetic functions. Accumulated evidence suggests that acetylcholine, (ACh), released from growing axons, regulates growth, differentiation, and plasticity of developing central nervous system neurons. In addition to intrinsic cholinergic neurons, the cerebral cortex and hippocampus receive extensive innervation from cholinergic neurons in the basal forebrain, beginning prenatally and continuing throughout the period of active growth and synaptogenesis. Acute exposure to ethanol in early gestation (which prevents formation of basal forebrain cholinergic neurons) or neonatal lesioning of basal forebrain cholinergic neurons, significantly compromises cortical development and produces persistent impairment of cognitive functions. Neonatal visual deprivation alters developmental expression of muscarinic acetylcholine receptors (mAChR) in visual cortex, whereas local infusion of mAChR antagonists impairs plasticity of visual cortical neurons. These findings raise the possibility that exposure to environmental neurotoxins that affect cholinergic systems may seriously compromise brain development and have long-lasting morphologic, neurochemical, and functional consequences.

AN - 21251309; 11703758 AB - The divalent calcium cation Ca(2+) is used as a major signaling molecule during cell signal transduction to regulate energy output, cellular metabolism, and phenotype. The basis to the signaling role of Ca(2+) is an intricate network of cellular channels and transporters that allow a low resting concentration of Ca(2+) in the cytosol of the cell ([Ca(2+)]i) but that are also coupled to major dynamic and rapidly exchanging stores. This enables extracellular signals from hormones and growth factors to be transduced as [Ca(2+)]i spikes that are amplitude and frequency encoded. There is considerable evidence that a number of toxic environmental chemicals target these Ca(2+) signaling processes, alter them, and induce cell death by apoptosis. Two major pathways for apoptosis will be considered. The first one involves Ca(2+)-mediated expression of ligands that bind to and activate death receptors such as CD95 (Fas, APO-1). In the second pathway, Ca(2+) has a direct toxic effect and its primary targets include the mitochondria and the endoplasmic reticulum (ER). Mitochondria may respond to an apoptotic Ca(2+) signal by the selective release of cytochrome c or through enhanced production of reactive oxygen species and opening of an inner mitochondrial membrane pore. Toxic agents such as the environmental pollutant tributyltin or the natural plant product thapsigargin, which deplete the ER Ca(2+) stores, will induce as a direct result of this effect the opening of plasma membrane Ca(2+) channels and an ER stress response. In contrast, under some conditions, Ca(2+) signals may be cytoprotective and antagonize the apoptotic machinery.

While it is known that significant genetic diversity occurs in the C. pecorum strains infecting koalas, very little is known about the C. pneumoniae strains that infect this host. In the current study, 10 isolates of koala C. pneumoniae were analysed at four gene loci and found to be different to both the human and horse C. pneumoniae strains at all loci (biovar differences ranging from 0.3% at groESL up to 9.0% at ompAVD4). All koala biovar isolates studied were found to be 100% identical at ompAVD4 (all 10 isolates) and at ompB (all three isolates) genes. This lack of allelic polymorphisms at ompAVD4 has now been observed for koala C. pneumoniae, human C. pneumoniae, guinea pig inclusion conjuctivitis C. psittaci and feline conjuctivitis C. psittaci and may be correlated to a lack of antibody response to the chlamydial major outer membrane protein (MOMP) in these same strain/host combinations. This study also provides the first documented case of natural C. pneumoniae infection causing a severe and extended respiratory episode in a captive koala population. This captive episode is in contrast to most free-range observations in which koala C. pneumoniae is rarely documented as causing respiratory, ocular or urogenital tract disease.

Since some studies have shown that irrigation with waste water can lead to contamination of groundwater resources, there is need for a model to predict the fate of irrigated water, salt, and nitrogen that can be applied to a variety of different soils, climates, and crops. We present the development of the water balance part of such a model, APSIM for Effluent, and carry out a comparison against data obtained from an effluent-irrigated plantation of Eucalyptus grandis. Over 10 months, modelled tree water use was within 1.5% of that obtained by sap-flux measurements. When compared over 5 years of the experiment, modelled drainage lay above that estimated by a water balance technique, which was known a priori to underestimate drainage, and was close to that estimated by the chloride mass balance technique. Simulated chloride accumulated in the soil was within the scatter of the observations, although it was consistently at the lower end of the range of the data. There was good agreement between the model predictions and measured chloride concentration distribution with depth in the soil. A considerable amount of water was lost as deep drainage, even for the treatment that aimed to add only enough effluent to replace that lost by evaporation. During 5 years, of the 3370 mm rainfall and 4480 mm effluent received by that treatment, 6710 mm was lost by the various evaporative routes, and 1080 mm was lost by deep drainage.

Seoul contains few major industrial sources of ambient-air pollution, whereas Ulsan is highly industrialized. Ambient-air concentrations were collected in each city and analyzed for concentrations of total suspended particulates, sulfur dioxide, nitrogen dioxide, ozone, and carbon monoxide. The death counts per day were matched to the daily averaged levels of total suspended particulates, SO sub(2), and the 1-h daily maximum level of O sub(3) on the same day. Results showed that the total suspended particulate and O sub(3) levels in Seoul were higher than those measured in Ulsan. The data revealed that each pollutant was associated highly with daily mortality, especially SO sub(2) and O sub(3). This association was found at pollution levels well below the national ambient-air-quality standards of many developed countries.

AN - 14512599; 10569336 AB - Chemicals that mimic estrogen and estradiol have demonstrated sex-reversal effects in turtle embryos similar to those shown by endogenous estrogens. Because the acceptable exposure considered to be safe is rarely tested, safety depends on the validity of the threshold assumption. Results are presented from a study in which the threshold hypothesis for estradiol was tested using red-eared slider turtles, and the resulting data were used to develop a biologically based doseresponse model. The resulting model indicated that no exogenous estradiol concentration was without risk, because endogenous estrogens were already at a sufficiently high concentration to exceed the threshold for sex reversal in this specie.

At both stations, pumps dispensed 95- and 99-research octane number (RON) gasoline, and 98-RON gasoline/diesel oil. The geometric mean concentrations of MTBE and TAME in the individual air samples were 3.9 and 2.3 mg/m super(3) at one station and 2.4 and 1.6 mg/m super(3) at the other, respectively. The highest means of C sub(6) alkyl methyl ethers were measured for 2-methyl-2-methoxypentane, at 0.32 and 0.22 mg/m super(3) at the two stations, respectively, while the mean concentrations of benzene were 1.0 and 0.77 mg/m super(3), respectively. The levels of both MTBE and TAME in the individual samples varied widely, from below detection limits to concentrations at least 1000 times higher. On average, a customer was exposed to an MTBE and a TAME concentration of 3.3 and 1.9 mg/m super(3), respectively, for 1 min.

A series of experiments was conducted in which breast-implant distillate containing hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane (CS-D4), decamethylcyclopentasiloxane, and dodecamethylcyclohexasiloxane was administered to female mice, as well as CS-D4 alone, and histopathology was evaluated. Results showed that histopathology on tissues obtained from mice surviving to 14 d revealed lung, liver, and peritoneal changes. Lungs showed interstitial inflammation consisting of lymphocytes and neutrophils, edema, and thromboemboli in small to mid-size vessels, while in liver, individual hepatocyte necrosis, areas of regenerating hepatocytes, giant cells, clusters of proliferating oval or bile duct cells, Kupffer cell proliferation, and neutrophils predominantly around the central veins were observed. These effects were even more severe in mice treated with CS-D4 alone, along with dramatic increases in hydroxyl radical formation in the liver and lungs.

These compounds have been implicated in the process of temperature-dependent sex determination. In this study, various combinations of three natural estrogens-estrone, estradiol, and estriolere examined in terms of their synergy in sex reversal of turtle embryos incubated at a male-producing temperature. Results show that, for single hormone treatments, sex reversal occurred in a dose-dependent manner, with estrone and estradiol exhibiting one-tenth the potency of estriol. This was also observed in the various paired combinations, with sex reversal especially dramatic for combinations of estriol and estradiol. When all three hormones were administered, no synergy was observed.

In an effort to assess the possible relationship between El Nino and vectorborne disease transmission, monthly reports of dengue fever cases were obtained for 22 islands in the region and compared with climatological data. Positive correlations were found between the southern oscillation index, which is the normalized difference in atmospheric pressure between Darwin, Australia, and Tahiti, and dengue fever in 10 countries. When the southern oscillation index was positive, much of the Central Pacific tended to be both wetter and warmer than usual. Other factors were also found to be important, however, such as island ecology, population size and density, and movement in modulating dengue fever transmission.

Electrophilicity was defined as the ability of a chemical to induce mutations in Salmonella. A total of 767 chemicals were used to construct the submodels. Results showed that 28% of the 384 allergic contact dermatitis-inducing agents were predicted to be mutagens, while only 6% of the noninducing chemicals were predicted to be mutagens, which suggested that electrophilicity was associated with allergic contact dermatitis. The considerable overlap in the submodels, however, indicated that the induction of allergic contact dermatitis is not due solely to electrophilicity.

In New Jersey, 49 female subjects were studied to examine the relationship between drinking water concentrations of disinfection byproducts and two biomarkers: exhaled breath measurements of trihalomethanes after showering, and urinary dichloroacetic acid and trichloroacetic acid excretion rates. A questionnaire was used to obtain data on water use in each home. Results showed that approximately equal numbers of homes had total trihalomethane and haloacetic acid concentrations above and below 10 mu g/l. The urinary trichloroacetic acid excretion rate demonstrated a doseresponse relationship with exposure to disinfection byproducts during routine household use over a 48-h time period, but dichloroacetic acid did not. The water concentration did not have a statistically significant relationship with the excretion rate for either compound.

A micro-proton-induced X-ray emission technique was used to assess the uptake of Pb by the cells. Results show that, after 30 min of exposure to 500 mu M Pb, the majority of the Pb was localized at the cell surface, with binding to sulfhydryl groups involved. The transport of dl-DMSA across the cell monolayer was significantly greater than for meso-DMSA. dl-DMSA removed significantly more Pb from the cells than did meso-DMSA.

Results showed that most mink livers contained detectable concentrations of PCBs and DDTs, and several also contained dieldrin. Most otter livers contained detectable concentrations of PCBs, p,p'-DDE, and heptachlor epoxide. In both species, hepatic concentrations of organochlorine pesticides and PCBs were correlated in males but not in females. The highest concentrations of TCDD toxic equivalents were found in an otter pool from the lower Fraser River, followed by a pool from the lower Columbia River. Few significant relationships among biological parameters and organochlorine pesticide and PCB concentrations were found in mink, and none were found in otters. There were, however, significant correlations between male mink baculum size and hepatic PCB concentrations, and baculum mass and total pesticide concentrations.

Whereas this model can account for many properties of motion vision, from humans to insects (review, Borst and Egelhaaf 1989), it has been commonly assumed that this scheme of motion detection is not well suited to the measurement of image velocity. This is because the commonly used version of the model, which incorporates two unidirectional motion detectors with opposite preferred directions, produces a response which varies not only with the velocity of the image, but also with its spatial structure and contrast. On the other hand, information on image velocity can be crucial in various contexts, and a number of recent behavioural experiments suggest that insects do extract velocity for navigational purposes (review, Srinivasan et al. 1996). Here we show that other versions of the correlation model, which consists of a single unidirectional motion detector or incorporates two oppositely directed detectors with unequal sensitivities, produce responses which vary with image speed and display tuning curves that are substantially independent of the spatial structure of the image. This surprising feature suggests simple strategies of reducing ambiguities in the estimation of speed by using components of neural hardware that are already known to exist in the visual system.

There is both historical and contemporary interest in understanding the degree to which these systems capture the natural aesthetic resource. In Tasmania, pictorial content analysis was used to quantify the relative contributions of different natural landscape elements to the resource, using pictorial content analysis in three time periods. The relative weights of the elements differed little between the time periods. Scores for the resource within 10 km x 10 km grid squares were derived, based largely on these weights, and changes in reservation of the resource were quantified for 1937, 1970 and 1992. There was a marked increase in the absolute representation of the natural aesthetic resource through time, although mean scores for grid squares declined in toto and for all scenic elements except coasts. The techniques used could be valuable for both assessing and planning the expansion of reserve systems.

Spraying of C. lugubris and the C. bimaculata eggs supplied as food showed that neither Novodor registered FC with active nor inactive Btt caused any decrease in predatory performance, longevity or fecundity of C. lugubris during the period of their population peak (December). Towards the end of their peak population levels, in late January, there was a steady increase in mortality which was not related to either of the Novodor registered FC treatments. On average, male:female pairs of C. lugubris laid one egg batch and ate 30 C. bimaculata eggs a week whether untreated or sprayed with either Novodor registered FC. This Btt-based insecticide appears to be a suitable component of an integrated pest management (IPM) regime that aims to conserve natural predators.

This damage is thought to reduce plantation productivity by reducing seedling growth, reducing seedling survival and promoting the development of multiple leaders. We report a study which quantified the effects of browsing damage on Eucalyptus nitens seedling. Twelve months after planting, severity of browsing, net growth rate (daily change in height), survival and number of leading shoots was compared between fenced and unfenced seedlings at seven forestry plantations. Browsing damage significantly reduced net growth rate of unfenced seedlings at five plantations. The amount by which net growth was reduced was linearly related to a measure of browsing damage severity (r super(2)=0.907, df=6, p<0.01). Significant reduction in growth occurred where mean browsing score exceeded 0.88. Unfenced seedlings with intermediate levels of damage developed more leading shoots than fenced seedlings. Seedling survival was unaffected by browsing damage at 12 months. The findings of this study can be used by forestry managers to assign meaningful measures of loss in height growth to observed levels of browsing damage, and to specifically identify 'acceptable' levels of damage.

Once these inputs are encoded perceptually, they may of course be recoded linguistically. Any interactive processes across modalities may then be assumed to take place in at least two regions in the information stream, viz., at the sensory level,or at the cognitive level. The present proposal deals with the study of interactions between visual, auditory, and tactual signals; in particular, the interest of the present research is in a set of phenomena that can be called congruence effects. These are characterized as effects that occur when the subject is asked to identify a target stimulus in a particular modality when there is simultaneously presented an irrelevant stimulus in another modality. When the irrelevant stimulus agrees with, or matches in some dimension, or is congruent to the relevant one, research has shown that both identification time and accuracy improve in comparison with the condition in which the irrelevant stimulus is incongruent with the target. A simple example of the phenomenon can be cited: When subjects are asked to identify a high-pitched tone, they will do so more rapidly and accurately when it is accompanied by a visual stimulus that is high in visual space, compared with when accompanied by a spatially low visual stimulus. By the same token, a low-pitched tone will be more efficiently processed when accompanied by a spatially low visual stimulus than a high one. The principal investigator has already demonstrated the existence of the congruence effect in a number of studies, and now proposes to extend this area of research with a series of experiments that test whether the effect, either as interference with or as facilitation of processing, lies more in the realm of elementary sensory events or in later events involving linguistic recoding. It is his plan to examine the effects of reducing the possibility of interactions at what he calls the semantic level by, for example, taking advantage of the bilateral asymmetry of the auditory system for linguistic input. Because of the well-known advantage of the left ear over the right (in most subjects) for processing language, it should be possible to demonstrate whether congruence of visual events having semantic value with auditory ones will produce an improvement in processing. In addition, the principal investigator will repeat some of the proposed experiments on a separate group of subjects who report synesthetic experiences. These are persons who, for example, experience sounds not only auditorily but also visually, having vivid color experiences in addition to the auditory perceptions. Because these persons exhibit a rather fixed relation of the two modal perceptions, e.g., a specific hue is always perceived when a particular sound pattern occurs, the production of congruent and incongruent stimuli must be tailored to each subject's personal cross-modal pairs. Otherwise, congruence/incongruence effects will not be detected. Owing to the fact that the frequency of occurrence of synesthesia in the general population is rather low, the expectation is that only a few subjects will be found in the three-year period devoted to the grant. These and similar manipulations of the relations between the sensory dimensions and their semantic valences provides the basis for the testing of a small set of elementary quantitative models of the interaction process. The results of this work may very well prove of significant use in the development of sensory aids that use more than one modality for communication (e.g., visual-tactual or auditory-kinesthetic combinations), in addition to advancing our knowledge of the structural relations among cognitive events.

AN - 69561385; 9892418 AB - Vascular endothelial growth factor (VEGF) is a cytokine with main angiogenetic functions in embryonic development and tumor-formation. In the adult lung, reports of the localization of VEGF were controversial. A precise cell typing of VEGF-positive pulmonary cells is still lacking. Nothing is known about a potential role in pulmonary fibrosis. Immunohistochemistry (IH), double immunofluorescence microscopy (DIF), and immunoelectron microscopy (IEM) were used to study the differential distribution of VEGF in paraffin-embedded (IH, DIF) and in cryo-substituted, Lowicryl-embedded (IEM) specimens of normal rat and human lungs and fibrotic rat lungs. Fibrosis was induced by intratracheal bleomycin treatment. IH and DIF showed that VEGF was present in surfactant protein (SP) D-positive alveolar type II pneumocytes, bronchiolar Clara cells, smooth muscle (SM) cells, and alpha-SM actin-positive myofibroblasts of normal rat and human lungs. Fibrotic lesions in bleomycin-treated rat lungs were rich in VEGF-positive cells presenting with a heterogeneous phenotype (mainly SP-D-positive type II pneumocytes, alpha-SM actin-positive myofibroblasts). There were no signs of angiogenesis. Post-embedding immunogold labeling using protein A-gold and IgG-gold technique revealed a specific localization of VEGF to mitochondria, Clara cell secretory granules, and capillary interendothelial cell junctions. The predominant localization of VEGF to bronchiolar and alveolar epithelial and alpha-SM actin-positive cells, and the marked increase of VEGF-positive type II pneumocytes and myofibroblasts in fibrotic lung lesions, indicate that in adult lungs VEGF is involved in processes other than angiogenesis.

AN - 69411749; 10656175 AB - Infection with human immunodeficiency virus type-1 (HIV-1) requires the presence of a CD4 molecule and chemokine receptors such as CXCR4 or CCR5 on the surface of target cells. However, it is still not clear how the virus enters the cells. Although CD4 was initially identified as the primary receptor for HIV-1, the expression of CD4 or one of the chemokine receptors alone is not sufficient to render susceptibility to infection with the virus. To ascertain whether or not adsorption of the virus needs charge-to-charge interaction between viral envelope and host cell membrane protein(s) and if binding alone promotes penetration of the virus into the cells, we have developed a chemically induced infection system targeting a CD4-negative and CXCR4-positive HeLa cell clone (N7 HeLa) which is usually not susceptible to infection with the LAI strain of HIV-1. Use of a poly-L-lysine (PLL)-coated culture plate to enhance the attachment of the virus to the cells made N7 HeLa cells infectable with HIV-1 at very low efficiency. PLL alone cannot fully substitute for the function of the CD4 molecule. However, trypsin-treated viruses, which have largely lost infectivity to CD4-positive MT-4 cells that are highly susceptible to HIV-1 infection, enhanced infectivity against N7 HeLa cells when the PLL-coated plate was used. These results provide evidence that infection with HIV-1 requires both high binding affinity between viruses and cells, and then needs a modification of the viral envelope such as cleavage of gp120/160 to enhance the infection, probably resulting in exposure of the hydrophobic fusion domain of gp41. HIV-1 infection of N7 HeLa cells was also enhanced by treatment with low pH, 12-O-tetradecanoylphorbol-13-acetate (TPA) and some factor(s) from the MT-4 cell culture supernatant. Not only tight viral adsorption with cleavage of the viral envelope but also some activated status of the cells may be required for sufficient HIV-1 infection in this artificial condition.

AN - 69273672; 10563888 AB - The broad-spectrum, systemic fungicides propiconazole (1) and tebuconazole (2) are used to control rust in peppermint (Mentha piperita L.). An analytical method, using gas chromatography combined with detection by high-resolution mass spectrometry, was developed to allow for the simultaneous monitoring of both pesticides in peppermint leaves and oil. Field trials were established to determine the rate of dissipation of tebuconazole and propiconazole in peppermint crops. Three applications of each fungicide were trialed at two rates (125 and 250 g of active ingredient (ai)/ha). At harvest, 64 days after the final application, propiconazole was detected at levels of 0.06 mg/kg and 0.09 mg/kg of dry weight, and tebuconazole was detected at 0.26 and 0.80 mg/kg dry weight, in identical trials. Rates of dissipation of propiconazole and tebuconazole were lower at a second trial site, where three applications of 125 g/ha ai for each fungicide resulted in residue levels of 0.21 mg/kg for both pesticides, detected 89 days after the last application. Propiconazole and tebuconazole were detected in the distilled oil at levels between 0.02 and 0.05 mg/kg and between 0.011 and 0.041 mg/kg, respectively. Propiconazole had a higher tendency to co-distill with the peppermint oil, with 0.7% of that present in the vegetative material ending up in the oil, compared to 0.09% of tebuconazole.

Statistical Analysis Report. AN - 62490716; ED427433 AB - This volume examines education-reform efforts in U.S. public schools. The report, which focuses on higher standards for student achievement, is based on two nation-wide studies: the Public School Teacher Survey on Education Reform and the Public School Survey on Education Reform. The survey included questions on teachers' understanding of higher standards for student achievement; how prepared teachers feel to set or apply new higher standards of achievement for their students; and the extent to which teachers are implementing reform activities. Survey findings are presented throughout the report in aggregates for all schools; where significant differences were found, they are presented by school characteristics. Among the findings, 42 percent of elementary and secondary public school teachers reported understanding the concept of new higher standards for student achievement very well, and 35 percent said they felt very well equipped to set or apply new higher standards for their students; two activities associated with education reform were frequently cited by teachers as being incorporated into their classes to a great extent; and instructional strategies were aligned with high standards to help all students succeed. Three appendices present the survey methodology, reference and standard error tables, and the survey form.

The 1998 survey is based on a sample of 2,500 of the nation's 15,718 public library outlets. The survey found that 73.3% of public library outlets now offer public access to the Internet. However, only 68.6% offer graphical public Internet access to the World Wide Web (WWW) and only 45.3% offer graphical public access to the WWW at speeds of 56 kbps or greater. The first section contains background information: the Telecommunications Act of 1996; public policy debate; information technology, Internet and the digital economy; and public libraries as a public point of Internet presence. The second section presents the results of the 1998 survey: availability of public Internet access; public Internet access for areas with varying levels of poverty; public Internet access for urban, suburban, and rural areas; graphical public Internet access; bandwidth as a component of public Internet access; defining effective public Internet access; key measures connectivity and public Internet access, 1996-1998; number of graphical workstations as a component of effective access; use of filtering software and availability of an acceptable use policy for public Internet access. The third section discusses findings, policy issues, and commission responses: supporting ongoing surveys on public libraries and the Internet; initiating a dialog on effective public Internet access; and identifying policy questions and promoting additional research. The last section is a bibliography of 8 statistical studies funded by the commission. Five appendices contain: summary results; the survey instrument; the survey methodology; the survey results; and the contractor's analysis of the survey results.

The first one, "The Outlook for College Graduates, 1996-2006: Prepare Yourself" (Mark Mittelhauser), concludes that there are more jobseekers with college degrees than there are openings of college-level jobs. "The Class of 1993: One Year After Graduation" (Megan Barkume) reports on a survey of these graduates' employment status, continuing education status, academic performance, earnings, and employment in specific fields. The next article, "Trends in College Degrees" (Jonathan W. Kelinson), identifies trends in college degrees by educational level, field of study, and by college enrollment characteristics. The next paper, "Earnings of College Graduates in 1996" (Theresa Cosca), analyzes the median earnings for 1996 college graduates, the kinds of jobs they held, and the proportion of college graduates who earned less than the median for high school graduates. The final paper, "Occupations and Earnings of Workers with Some College But No Degree" (Daniel Hecker), compares occupational employment patterns and earnings data of this group with workers who have only a high school diploma and with those who have associate and bachelor's degrees.

AN - 62477850; ED431373 AB - This publication reviews the history of the Professional Staff Congress (PSC) of the City University of New York (CUNY), which in 1997 celebrated its 25th anniversary, commemorating the 1972 merger of the institution's Legislative Conference and the United Federation of College Teachers, two previously rival unions. The first chapter covers the union's origins, the differing perspectives of its parent organizations, and the steps toward merger. The second chapter addresses the effects of the New York City fiscal crisis in the 1970s. It recalls the series of budgetary cuts imposed on the university, a retrenchment proposal, the PSC fight for full state funding, various restructuring plans, the shutdown of CUNY, and the achievement of full state funding. The third chapter covers 1980s, which is seen as a decade of advance. Subsections review the continuing battles against budget cuts, the Cuomo years, protection of retiree benefits, contractual gains, strengthening of the welfare fund, establishment of a credit union, and the establishment of scholarships. The final chapter, covering the 1990s, sees the decade as a period of defending PSC achievements, including agreement on a new contract, weathering new problems, restoration of some cuts, and a PSC lawsuit in the State Supreme Court. Timelines at the end of each chapter list important events.

National and State Data on the Pay Gap and Its Costs. A Joint Research Project. AN - 62470026; ED429231 AB - A national study, including state-by-state breakouts, analyzed Census Bureau and Bureau of Labor Statistics data to explore the wage gap. Median weekly earnings of men and women and of minorities and nonminorities were analyzed. Gender-based earnings differences and gender wage gaps were large for all women--and especially large for minority women--compared with all men. Minority-based wage gaps were substantial. The study estimated that, if married women earned as much as comparable men, their family incomes would rise by nearly 6 percent; if single working mothers earned as much as comparable men, their family incomes would increase by nearly 17 percent; if single working women earned as much as comparable men, their incomes would rise by 13.4 percent; and working women in every state would receive wage hikes if they earned as much as comparable men in their states. Comparison of earnings of workers in female-dominated jobs with comparable workers in other jobs showed very large earnings losses due to the lower pay associated with working in female-dominated jobs. The considerable advantage unionized workers enjoy, both in the form of higher wages and smaller wage gaps, was reviewed.

AN - 62399522; ED440021 AB - A number of recent studies represent a growing consensus among many religious and educational groups about the constitutional and educational role of religion in the public schools. This pamphlet is designed to build on these agreements and to encourage communities to find common ground when they are divided. The pamphlet presents 15 questions and answers that are intended to help parents understand the religious liberty rights of students and the appropriate role for religion in the public school curriculum. The questions and answers provide general information on the subject of religious expression and practices in schools. The answers are based on First Amendment religious liberty principles as currently interpreted by the courts and agreed to by a wide range of religious and educational organizations. The pamphlet cautions that the law alone cannot answer every question and advises that parents in each community must work with school officials to do not only what is constitutional, but also what is "right" for all citizens. It points out that the religious liberty principles of the First Amendment provide the civic framework within which citizens are able to debate differences, to understand one another, and to forge school policies that serve the common good in public education.

An opening statement of Senator Pete Domenici outlined the problem of an epidemic of black tar heroin addiction afflicting the county, with accompanying crime and delinquency problems. A representative of the federal Office of Justice Programs (OJP) described relevant OJP initiatives, particularly Weed and Seed, which provides funding for community law enforcement, drug treatment programs, and after-school youth activities aimed at drug and delinquency prevention. Other federal officials discussed block grants and state incentive grants for drug prevention and treatment programs, the Starting Early Starting Smart program for children aged 0-7, physical and mental health problems related to drug abuse, the science of heroin addiction and treatment, and science-based drug education materials for grades 5-9. Representatives of state and local agencies discussed substance abuse-related detention costs; substance abuse, mental health, and related medical costs for local prisoners; the Rio Arriba Strategic Plan for Substance and Alcohol Abuse and Treatment; the rationale for a county-wide plan; current substance abuse reduction activities in the county; youth development as primary prevention; the high rates of drug-related death in New Mexico; the special problems of isolated rural communities; and a drug treatment program based on yoga, meditation, and nutrition.

AN - 62394833; ED433044 AB - The State Library Agencies (STLA) Survey is conducted annually and is the product of a cooperative effort between the Chief Officers of State Library Agencies (COSLA), the U.S. National Commission on Libraries and Information Science (NCLIS), and the National Center for Education Statistics (NCES). This fourth Survey in the series provides state and federal policymakers, researchers, and other interested users with descriptive information about state library agencies in the 50 states and the District of Columbia for fiscal year (FY) 1997. The Survey collects data on 506 items, including governance, public service hours, service outlets, collections, library service and development transactions, support of electronic information networks, allied operations, staff, income and expenditures. Data are also collected on STLA services to public, academic, school and special libraries, and to library systems. The data items and definitions are provided in the survey facsimile at the end of the data base documentation. Data items on films, special collections, and combined libraries collected in previous years were deleted from the FY97 survey, based on their declining significance or data quality, as determined by the STLA Steering Committee. Data on staff by gender and race/ethnicity were collected by full-time/part-time status, rather than in full-time equivalents (FTEs), due to the difficulty in providing the FTE data in previous years.

The data are collected by a network of state data coordinators appointed by the chief officers of state library agencies in the 50 States and the District of Columbia. The FY96 PLS collected data on 50 items for public libraries--38 basic items and 12 identifying items. The basic data include population of legal service area, number of full-time equivalent staff, outlets, library materials, operating income and expenditures, capital outlay, circulation, reference transactions, library visits, public service hours, interlibrary loans, circulation of children's materials, children's program attendance, and several items on electronic technology (i.e., expenditures for materials in electronic format, expenditures for electronic access, materials in electronic format, access to electronic services, access to the Internet, and type of Internet use). Identifying information includes the entity's name, address, telephone number, county, interlibrary relationship, type of governance, administrative structure, and its qualification as a Federal-State Cooperative System (FSCS) public library. The survey collected 12 items on each public library outlet and state library outlet. These items include type of outlet, metropolitan location, population of legal service area, and number of bookmobiles. The survey also collected data on 11 identifying items on state library agencies, systems, federations, and cooperatives. Four items were collected on characteristics of the state data submission (i.e., the starting and ending dates of the FY reporting period, the official state population estimate, and the total unduplicated population of legal service areas for the state).
