Abstract
We report on a search for neutrinoless double-beta decay of 136Xe with EXO-200. No signal is observed for an exposure of 32.5 kg yr, with a background of ∼1.5×10(-3) kg(-1) yr(-1) keV(-1) in the ±1σ region of interest. This sets a lower limit on the half-life of the neutrinoless double-beta decay T(1/2)(0νββ)(136Xe)>1.6×10(25) yr (90% C.L.), corresponding to effective Majorana masses of less than 140-380 meV, depending on the matrix element calculation.

Abstract
We report the observation of two-neutrino double-beta decay in (136)Xe with T(1/2) = 2.11 ± 0.04(stat) ± 0.21(syst) × 10(21) yr. This second-order process, predicted by the standard model, has been observed for several nuclei but not for (136)Xe. The observed decay rate provides new input to matrix element calculations and to the search for the more interesting neutrinoless double-beta decay, the most sensitive probe for the existence of Majorana particles and the measurement of the neutrino mass scale.

Abstract
BACKGROUND Interpersonal functioning is central to social anxiety disorder (SAD). Empirical examinations of interpersonal behaviors in individuals with SAD have frequently relied on analogue samples, global retrospective reports and laboratory observation. Moreover, research has focused on avoidance and safety behaviors, neglecting potential links between SAD and affiliative behaviors. METHOD The influence of situational anxiety and emotional security on interpersonal behaviors was examined for individuals with SAD (n=40) and matched normal controls (n=40). Participants monitored their behavior and affect in naturally occurring social interactions using an event-contingent recording procedure. RESULTS Individuals with SAD reported higher levels of submissive behavior and lower levels of dominant behavior relative to controls. Consistent with cognitive-behavioral and evolutionary theories, elevated anxiety in specific events predicted increased submissiveness among individuals with SAD. Consistent with attachment theory, elevations in event-level emotional security were associated with increased affiliative behaviors (increased agreeable behavior and decreased quarrelsome behavior) among members of the SAD group. Results were not accounted for by concurrent elevations in sadness or between-group differences in the distribution of social partners. CONCLUSIONS These findings are consistent with predictions based on several theoretical perspectives. Further, the present research documents naturally occurring interpersonal patterns of individuals with SAD and identifies conditions under which these individuals may view social interactions as opportunities for interpersonal connectedness.

Abstract
OBJECTIVE To describe the process of establishing and implementing a social support infant feeding intervention. DESIGN This paper outlines the initial stages of a randomised controlled trial which assessed the effectiveness of a social support intervention on a range of infant feeding outcomes. Details are presented of the processes involved in recruiting, training and supporting a group of volunteers who provided support to the study sample. SETTING Camden and Islington, London, UK. RESULTS Initial networking with local agencies and organisations provided invaluable information and contacts. Employing a dedicated volunteer co-ordinator is vitally important in the recruitment, training and support of volunteers. Providing child care and travel expenses is an essential incentive for volunteers with young children. Advertisements placed in local newspapers were the most successful means of recruiting volunteers. Appropriate training is needed to equip volunteers with the necessary knowledge and skills to provide effective support. Particular emphasis in the training focused upon developing the necessary interpersonal skills and self-confidence. The evaluation of the training programme demonstrated that it improved volunteers' knowledge and reported confidence. The provision of ongoing support is also essential to maintain volunteers' interest and enthusiasm. The retention of volunteers is, however, a key challenge. CONCLUSIONS The processes outlined in this paper have demonstrated the feasibility of successfully establishing, implementing and maintaining a community-based social support infant feeding programme. The experiences described provide useful insights into the practical issues that need to be addressed in setting up a social support intervention.

Abstract
Exploiting the manipulation of the SLAC Linear Collider electron-beam polarization, we present precise direct measurements of the parity-violation parameters A(c) and A(b) in the Z-boson-c-quark and Z-boson-b-quark coupling. Quark-antiquark discrimination is accomplished via a unique algorithm that takes advantage of the precise SLAC Large Detector charge coupled device vertex detector, employing the net charge of displaced vertices as well as the charge of kaons that emanate from those vertices. From the 1996-1998 sample of 400 000 Z decays, produced with an average beam polarization of 73.4%, we find A(c)=0.673+/-0.029(stat)+/-0.023(syst) and A(b)=0.919+/-0.018(stat)+/-0.017(syst).

Abstract
This report describes a whole body donation from a person with a documented occupational intake of uranium. USTUR Case 1002 was an adult male who died from an acute cerebellar infarct at the age of 83. He worked as a power operator, utility operator, and metal operator for 28 years in a facility that processed and handled radioactive materials. Although he suffered a number of burns from hot metal and acids, cuts, abrasions, and puncture wounds during his many years of work, there were no corresponding health physics or medical records to indicate that these occurrences needed or required excision or decontamination due to the suspicion of the deposition of radioactive material. Over the course of his employment, USTUR Case 1002 submitted numerous urine samples for uranium, plutonium, and fission product analysis. The highest single uranium value measured during this time period was approximately 30 microg L(-1) recorded during the second year of his employment. A urinary bioassay sample taken before termination of employment measured 4.3 microg L(-1). The mean urinary uranium concentration per liter per year calculated from the employee's bioassay records covering the first eleven years of monitoring averaged less than 3 microg L(-1). The ratio of 234/238U activity in the lung tissue was about 1, the same as that found in natural uranium. The highest concentration of uranium was found in a tracheobronchial lymph node. The uranium content in the various tissues of the body followed a rank order lung > skeleton > liver > kidney. Concentration of uranium in the kidney tissue was approximately 1.98 ng g(-1), about 3 orders of magnitude less than the generally accepted threshold level for permanent kidney damage of 3 microg U g(-1) and roughly equal to the 1.4 ng g(-1) reported for Reference Man. The autopsy disclosed findings not uncommon in the aged: severe atherosclerosis, areas of sclerotic kidney glomeruli with stromal fibrous scarring, and moderate to severe arterionephrosclerosis. Lung sections contained parenchymal areas of acute vascular congestion and a mild degree of anthracosis.

Abstract
We present an improved direct measurement of the parity-violation parameter A(b) in the Z boson-b-quark coupling using a self-calibrating track-charge technique applied to a sample enriched in Z-->bb events via the topological reconstruction of the B hadron mass. Manipulation of the Stanford Linear Collider electron-beam polarization permits the measurement of A(b) to be made independently of other Z-pole coupling parameters. From the 1996-1998 sample of 400,000 hadronic Z decays, produced with an average beam polarization of 73.4%, we find A(b)=0.906+/-0.022(stat)+/-0.023(syst).

Abstract
An analysis of 238Pu in the whole body donation to the U.S. Transuranium and Uranium Registries (USTUR) is presented. This donor accidentally inhaled an unusual physical form of plutonium, predominantly the 238Pu isotope in the form of a highly insoluble ceramic. Along with six other workers accidentally exposed at the same time, this donor excreted little or no 238Pu in his urine for several months. Subsequently, however, and, with no further intakes, the urinary excretion of 238Pu by all of these workers increased progressively. Such a pattern of increasing urinary excretion of plutonium resulting from a single acute inhalation was unknown at the time. The subject of this study provided a unique opportunity to analyze not only the pattern of urinary excretion for 17 y following this unusual intake but also the complete distribution of 238Pu in his donated body tissues and skeleton at death. Radiochemical analyses of tissues from this whole body donation were used to perform critical tests of the applicability and accuracy of the respiratory tract model and the systemic biokinetic models for plutonium currently recommended by the International Commission on Radiological Protection. The respiratory tract model was applied to analyze the donor's long-term urinary excretion pattern. The facility provided by this model to represent progressive transformation of insoluble particles in the lungs into a more soluble form, applied in conjunction with the systemic biokinetic model, predicted the total amount of 238Pu measured in the donor's body to within 17% accuracy. The measured division of 238Pu between the donor's lungs and systemic organs was predicted to within 10%. Small adjustments to several rate constants in these models provided precise predictions of the absolute amounts of 238Pu in the lungs, thoracic lymph nodes, liver, red bone marrow, skeleton (including the distribution of 238Pu between trabecular and cortical bone matrices derived from the radiochemical analyses), kidneys, testes, and muscle. The resulting individual-specific parameters were applied to evaluate the equivalent dose rates and cumulative doses received by the donor's organs and the overall effective dose. Whereas these individual modifications to the ICRP models provided a more accurate representation of the distribution of dose between the donor's organs, it was determined that the ICRP models provided an adequate estimate of the overall effective dose.

Abstract
The United States Transuranium and Uranium Registries (USTUR) has analysed tissues collected at autopsies of over 300 former radiation workers from actinide processing sites throughout the US, in addition to collecting the medical and radiation exposure histories of those workers. These data are included in a large USTUR database and they are available to research scientists throughout the world, either as public records or through collaborative projects with the USTUR. The USTUR also operates the National Human Radiobiological Tissue Repository (NHRTR), in which portions of tissue samples collected at autopsy are kept. These samples, frozen at -70 degrees C, may be used for molecular studies of the effects of radiation. Medical and radiation exposure histories of the tissue donors are available, as are the results of radiochemical analyses of adjacent portions of the samples. These materials are available to researchers who have collaborative agreements with the USTUR, which can be established by accessing USTUR staff members through the website, http://www.ustur.wsu.edu.

Abstract
The placenta and umbilical cord were obtained following a normal live delivery from a volunteer donor who had received an accidental inhalation intake of plutonium 12 years prior to her pregnancy (Case 0777). Her employer estimated the intake to be about 73 Bq Class W plutonium. Based on bioassay results and clearance models in use at that time, they calculated her body content at the beginning of pregnancy to be about 5.6 Bq with an average concentration of approximately 60 mBq kg(-1). The placenta and cord from this pregnancy, along with the placenta and cord from a donor with no known exposure to plutonium (Case 0835), were divided and assayed for plutonium by ultrasensitive fission track analysis at two collaborating laboratories. Placental 239Pu concentration values obtained by the two laboratories for Case 0777 agreed within a factor of 2 and were several-fold greater than for the control, Case 0835, as well as values that had been reported by others for unexposed populations. There was no elevated concentration of plutonium in the umbilical cord from the exposed person. The data yielded values of 0.16 and 0.27 for placental to maternal concentrations (CPl: CM) that were of the same order of magnitude as the value of 0.1 the ICRP calculated for intakes before pregnancy.

Abstract
The parity violation parameters A(b) and A(c) of the Zb(b) and Zc(c) couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the Z(0) pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the analyzing power. Based on the 1993-1998 SLD sample of 550,000 Z(0) decays produced with highly polarized electron beams, we measure A(b) = 0.919+/-0.030(stat)+/-0.024(syst), and A(c) = 0.583+/-0.055(stat)+/-0.055(syst).

Abstract
We present measurements of time-dependent CP-violating asymmetries in neutral B decays to several CP eigenstates. The measurement uses a data sample of 23x10(6) Upsilon(4S)-->BbarB decays collected by the BABAR detector at the PEP-II asymmetric B Factory at SLAC. In this sample, we find events in which one neutral B meson is fully reconstructed in a CP eigenstate containing charmonium and the flavor of the other neutral B meson is determined from its decay products. The amplitude of the CP-violating asymmetry, which in the standard model is proportional to sin2beta, is derived from the decay time distributions in such events. The result is sin2beta = 0.34+/-0.20 (stat)+/-0.05 (syst).

Abstract
We present final measurements of the Z boson-lepton coupling asymmetry parameters A(e), A(mu), and A(tau) with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the left-right production and decay polar angle asymmetries in leptonic Z decays we measure A(e) = 0.1544+/-0.0060, A(mu) = 0.142+/-0.015, and A(tau) = 0.136+/-0.015. Combined with our left-right asymmetry measured from hadronic decays, we find A(e) = 0.1516+/-0.0021. Assuming lepton universality, we obtain a combined effective weak mixing angle of sin (2)theta(eff)(W) = 0.230 98+/-0.000 26.

We have made the first direct symmetry tests in the decays of polarized Z0 bosons into fully identified bbg states, collected in the SLD experiment at SLAC. We searched for evidence of parity violation at the bbg vertex by studying the asymmetries in the b-quark polar- and azimuthal-angle distributions, and for evidence of T-odd, CP-even or CP-odd, final-state interactions by measuring angular correlations between the three-jet plane and the Z0 polarization. We found results consistent with standard model expectations and set 95% C. limits on anomalous contributions.

Abstract
Acne is a common problem in adolescents and young adults. The disorder is caused by abnormal desquamation of follicular epithelium that results in obstruction of the pilosebaceous canal. This obstruction leads to the formation of comedones, which can become inflamed because of overgrowth of Propionibacterium acnes. Topical retinoids such as tretinoin or adapalene are effective in many patients with comedonal acne. Patients with inflammatory lesions benefit from treatment with benzoyl peroxide, azelaic acid or topical antibiotics. Frequently, the use of comedonal and antibacterial agents is required.

Abstract
Kidney tissue sections were obtained at autopsy from seven persons with a history of low level occupational exposure to uranium and histologically compared in a blind study with similar sections obtained from six reference cases. The pathologist was unable to identify the uranium workers or any uranium-specific nephropathy. This suggests that the chronic low level of kidney uranium concentration experienced by these workers, which was an order of magnitude lower than the accepted permissible level of 3 microgram per gram, did not induce any identifiable permanent tissue damage.

Abstract
We quantified HIV-1 RNA levels (copies per milliliter) in cerebrospinal fluid (CSF) and serum from subjects at various stages of HIV-1 disease and determined the relationship of RNA levels to clinical and neurologic disease status (HND) and to laboratory values. Ninety-seven HIV-1-seropositive men without CNS opportunistic infections, tumors, or neurosyphilis and 13 high-risk seronegative controls were included in the study. Each individual underwent a structured interview and physical and neurologic examinations, followed by standardized collection of blood and CSF. A custom-designed, fully automated polymerase chain reaction (PCR) system was used to perform a minimum of four separate amplifications per specimen, using two HIV-1 gag primer pairs. Southern blotting followed by hybridization with product-specific probes was used for post-PCR detection. The number of copies per milliliter was determined by relating unknowns to a built-in dilution-series standard curve using an image analysis system. HIV-1 RNA was detectable in 96% of the sera, 78% of the concentrated CSF samples, and 54% of the unconcentrated CSF samples. Serum RNA levels were significantly higher than in CSF. Serum RNA levels were significantly inversely correlated with CD4+ cell counts (p = -0.34; p = 0.03): i.e., higher RNA levels in seropositive subjects were associated with lower numbers of CD4+ cells. Serum RNA levels correlated positively with number of AIDS-related symptoms, dysfunction scores for total neurological examination, mental status score, cranial nerve score, and CNS motor signs score. Serum RNA levels did not correlate significantly with length of time on zidovudine therapy, intrathecal IgG synthesis rate, or albumin leakage. RNA levels in CSF significantly correlated only with intrathecal IgG synthesis rate and with serum RNA levels. These results confirm that serum levels of HIV-1 RNA correlate with HND and inversely correlate with CD4 counts, demonstrating that HND occurs predominantly in late stages of HIV-1 disease, although HIV-1 RNA can be detected in CSF from a majority of HIV-1-seropositive individuals at all stages of disease, which suggests that there can be early penetration of HIV into the CNS. However, HND can occur in the absence of high levels of CSF HIV-1 RNA. We also found that the concentration of HIV-1 in CSF is correlated with intrathecal IgG synthesis rate.

Abstract
Previous studies from our laboratories have shown that catabolism of glutathione (GSH) by gamma-glutamyl transpeptidase (GGT) in the presence of transition metals leads to oxidative damage (OD). This damage is exemplified in vitro by GGT-dependent GSH mutagenesis which involves reactive oxygen species and by GGT-dependent accumulation of lipid peroxidation (LPO) products in systems containing polyunsaturated fatty acid and GSH. In order to test whether catabolism of GSH by membranal GGT in enzyme-altered preneoplastic hepatic lesions can induce oxidative damage in situ, and to test whether the OD is localized in these lesions, 21 day old Fischer rats were treated with 12 mg/kg diethylnitrosamine (DEN) followed by 0.1% or 0.25% phenobarbital (PB) in the diet. Cryostat sections were examined histochemically for GGT-rich hepatic lesions. Adjacent sections were incubated with GSH and iron and examined for areas staining for lipid peroxidation. Distinct LPO-positive areas were shown to correspond well with the GGT-positive hepatic lesions. Promotion with 0.25% PB led to increasing proportions of LPO-positive lesions with time among GGT-positive lesions. The visualization of LPO in GGT-rich hepatic lesions depended on the presence of GSH and iron, and was not observed following chelation of iron by diethyl triaminopentaacetic acid (DTPA), in the presence of acivicin, an inhibitor of GGT, or in the presence of the radical scavenger butylated hydroxytoluene (BHT). The factors affecting GSH-GGT-dependent LPO in the GGT-rich foci were identical to those affecting GSH-GGT-driven LPO in vitro, and were similar to those affecting oxidative GSH-mutagenesis catalyzed by GGT. The results indicate that metabolism of GSH by GGT in preneoplastic liver foci can initiate an oxidative process leading to a radical-rich environment and to oxidative damage. Such damage may contribute to the processes by which cells within such foci progress to malignancy.

Abstract
Mice of several strains (A/J, SWR, MaMyJ, BALB/cByJ, 129J, and C57BL/6J) were treated with the carcinogens 3-methylcholanthrene, urethane, and 4-nitroquinoline 1-oxide and then given 1 or 5% glycerol in the drinking water for up to 4 months. Effects of glycerol on lung tumor multiplicity and incidence were evaluated. The effects of glycerol were variable, and in the majority of experiments glycerol failed to enhance tumor development in mouse lung. Analysis of cell kinetics did not show a proliferative response of alveolar or bronchiolar cells to glycerol. In rats, glycerol did not enhance the appearance of putative preneoplastic liver foci, and in C3H mice it did not increase the incidence of spontaneously occurring liver tumors. It is concluded that glycerol does not increase number or incidence of lung tumors in the mouse strains used, whether the animals are pretreated with a carcinogen or not. Glycerol does not affect liver tumor development.

Abstract
Previous investigations in this laboratory have provided evidence that histochemically detectable altered hepatocyte foci and hepatic tumors appearing in rats given a single neonatal treatment with a low dose of carcinogen followed by chronic dietary phenobarbital administration are developmentally independent. The present investigation further evaluates developmental relationships among these lesions. Altered hepatocyte foci were divided into two subclasses consisting of foci that were detectable by histochemical as well as by hematoxylin-eosin staining [designated hist(+)/morph(+) foci] and those foci that were detectable solely by histochemical staining [designated hist(+)/morph(-) foci]. The developmental and phenotypic properties of the hist(+)/morph(-) foci, hist(+)/morph(+) foci, and hepatic tumors were compared in rats initiated once neonatally with different doses of diethylnitrosamine and promoted with dietary phenobarbital from weaning. The morph(+) and morph(-) lesion subclasses were distinguishable on the basis of several developmental characteristics. Hist(+)/morph(+) foci were present at low frequency until at least 150 days after initiation. Although the development of hist(+)/morph(-) foci was essentially complete at that point, the rate of appearance of hist(+)/morph(+) increased significantly. The diethylnitrosamine dose response of the hist(+)/morph(+) foci followed the histochemical marker patterns of the tumor lesion class more closely than that of the hist(+)/morph(-) group. The rates of expression of the hist(+)/morph(+) foci increased with the increasing level of histochemical complexity, whereas the rates of expression of the hist(+)/morph(-) foci groups were inversely correlated to their complexity level. Although the average focus size or diameter in the hist(+)/morph(+) groups was greater than that of the hist(+)/morph(-) foci, the focus growth rates of morph(+) and morph(-) subsets matched for histochemical phenotype were comparable. The complexity level and individual marker distribution patterns of the hist(+)/morph(+) focus class were more similar to tumor patterns than to the distribution patterns of the hist(+)/morph(-) lesion class. The results suggest the following. (a) The development of lesion classes with successively greater deviation from normalcy does not occur via lineal progression from less to more deviated forms within a given lesion class. The three lesion classes appear to develop independently, with the developmental characteristics of each lesion class determined at the time of initiation.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
To characterize the effects of combined treatments with gamma radiation and diethylnitrosamine (DEN) on the induction of histochemically detectable altered hepatocyte foci and hepatic tumors, we assessed the yields of these lesions in the livers of 150-day-old rats that had been treated neonatally with a single dose of gamma radiation (75 rad, whole body) and i.p.-injected DEN (0.15 mumol/g body wt), either separately or in combination. The combined treatments involved the administration of the two stimuli in both possible sequences, with the interval between treatments set at 1 h. The focus population was examined for two histochemical markers (elevated gamma-glutamyl transpeptidase [GGT(+)] and iron exclusion [FE(-)], giving rise to three detectable focus phenotypes, i.e. GGT(+) foci, FE(-) foci, and GGT(+), FE(-) foci. Frequencies of the three phenotypes were quantitated through the use of serial frozen sectioning techniques and computer-assisted image analysis. GGT(+) focus induction was synergistically enhanced by the combined treatment irrespective of the order in which the two stimuli were administered; the remaining two phenotypes did not show such enhancement. The magnitude of the GGT(+) focus response was significantly greater when the treatment sequence was gamma----DEN as opposed to DEN----gamma. Tumor yields in rats receiving combined gamma--DEN treatment were similar to those in rats receiving the DEN alone, irrespective of the gamma--DEN treatment sequence. These results suggest that phenotypically distinguishable lesions, including foci with different histochemical marker patterns and tumors, originate from specific types of damage at different genetic loci and are developmentally independent; and the expression of the GGT(+) marker per se in altered hepatocyte foci is not a reliable index of incipient hepatic neoplasia.

Abstract
To extend our ongoing characterization of modulatory influences on hepatic tumorigenesis, we examined effects of rat strain (Sprague-Dawley versus Fischer), diet composition (semipurified diet versus standard nonpurified laboratory chow), and dietary phenobarbital on the production of gamma-glutamyl transpeptidase (GGT)-positive hepatocyte foci and hepatic tumors initiated by diethylnitrosamine. In addition to GGT-positive foci, we observed, under certain conditions, the appearance of extensive hepatic GGT staining not associated with focal lesions. This elevated nonfocal GGT was found in rats of both strains fed the nonpurified rather than the purified diet, but the level of staining was higher in Fischer than in Sprague-Dawley rats. Enhancement of this nonfocal staining by dietary phenobarbital appeared insignificant. By comparison, frequencies of GGT-positive foci were generally higher in rats fed the semipurified rather than the nonpurified diet, and the frequencies of GGT-positive foci were invariably higher in Sprague-Dawley than in Fischer rats. Moreover, dietary phenobarbital generally enhanced focus production. Assessments of focus and tumor yields among these experimental groups showed that differences in focus frequencies did not correspond closely to differences in subsequent tumor formation. These results document the need to consider the influences of diet and rat strain on experimental end points in designing protocols for hepatocarcinogenesis studies, especially those involving GGT histochemistry. The data also raise questions about the mechanistic relevance of GGT induction to hepatocarcinogenesis and support our prior evidence against the putative lineal relationship between foci and tumors.
