Abstract
Prenatal alcohol exposure often results in fetal alcohol syndrome and fetal alcohol spectrum disorders. Mechanisms of fetal brain damage by alcohol remain unclear. We used baboons (Papio spp.) to study alcohol-driven changes in the fetal cerebral artery endocannabinoid system. Pregnant baboons were subjected to binge alcohol exposure via gastric infusion three times during a period equivalent to the second trimester of human pregnancy. A control group was infused with orange-flavored drink that was isocaloric to the alcohol-containing solution. Cesarean sections were performed at a time equivalent to the end of the second trimester of human pregnancy. Fetal cerebral arteries were harvested and subjected to in vitro pressurization followed by pharmacological profiling. During each alcohol-infusion episode, maternal blood alcohol concentrations (BAC) reached 80 mg/dL, that is, equivalent to the BAC considered legal intoxication in humans. Circulating anandamide (AEA) and 2-arachidonoylglycerol (2-AG) remained unchanged. Ultrasound studies on pregnant mothers revealed that fetal alcohol exposure decreased peak systolic blood velocity in middle cerebral arteries when compared to pre-alcohol levels. Moreover, ethanol-induced dilation was observed in fetal cerebral arteries pressurized in vitro. This dilation was abolished by the mixture of AM251 and AM630, which block cannabinoid receptors 1 and 2, respectively. In the presence of AM251, the cannabinoid receptor agonist AEA evoked a higher, concentration-dependent dilation of cerebral arteries from alcohol-exposed fetuses. The difference in AEA-induced cerebral artery dilation vanished in the presence of AM630. CB1 and CB2 receptor mRNA and protein levels were similar in cerebral arteries from alcohol-exposed and control-exposed fetuses. In summary, alcohol exposure dilates fetal cerebral arteries via endocannabinoid receptors and results in an increased function of CB2.

Abstract
In the USA, as well as internationally, rates of HIV infection among women continue to grow. In addition, women who inject drugs are at further increased risk for hepatitis C co-infection. The purpose of this study was to conduct qualitative and quantitative needs assessments for HIV/STD/hepatitis prevention among women in methadone maintenance programmes. Qualitative interviews and a quantitative, self-administered questionnaire were used to develop an understanding of their needs, and perceptions of what they believed would constitute effective prevention intervention programmes. Results supported women's interest in these services and provided feedback on how to structure prevention programmes by placing them in the context of women's lives and addressing concrete barriers (e. g. transportation, child care, confidentiality concerns) to facilitate adherence to these programmes. Respondents indicated a desire for HIV prevention information, but also wanted information on hepatitis, relapse prevention, stress management and accessing services. The development of such programming would require partnering with the target population and their service providers to develop feasible and effective interventions.

Abstract
The purpose of this study was to engage women with HIV disease in a qualitative needs assessment for psychological services. Focus groups/interviews were held to develop an understanding of these women's experiences and perceptions of services needed within a support group format. Results support women's interest in and perceived need for psychosocial group intervention and provide feedback on how to structure groups, including considerations for the facilitator, concrete barriers to address, and attention to group attributes and guidelines. These results support ongoing development of psychosocial support groups for women with HIV disease and further exploration of the efficacy of group models for the diverse subgroups of women with HIV/AIDS.

Abstract
An important responsibility of animal care programs is to protect research animals from exposure to potentially pathogenic microorganisms. To validate the need for steam sterilization of rodent automatic watering racks, we evaluate the post-sanitation microbial contamination of experimentally inoculated racks and of racks that had been used to house conventional mice. We tested three sanitation protocols: rack-washer sanitation without manifold flush, sanitation that included manifold flush, and sanitation that included manifold flush followed by autoclaving. Rack sanitation, with or without manifold flush, did not reliably eliminate microbial flora from the lixits or manifold drainage water. A total of 43% of all non-autoclaved racks were positive for bacterial contamination after sanitation, and racks that had been used for conventional animal housing were more frequently positive than were experimentally inoculated racks (79% vs 18%). These data indicate that steam sterilization is necessary for eliminating bacteria from automatic watering systems. These observations are particularly important in light of increasing numbers of immune-impaired rodents that may be inadvertently and unnecessarily exposed to microbial pathogens via the automatic watering system.

Abstract
We have previously demonstrated that mammalian reovirus type 1 enters the bile and gut lumen after systemic administration. In the present study, we showed that Kupffer cell uptake is essential for the transport of reovirus into the bile. Furthermore, class II major histocompatibility antigen (I-A)-bearing cells are a major determinant for the transit of reovirus from the hepatic environment, as well as from the intestine, during the course of systemic infection. These findings may provide an approach to the control of viral pathogens that cause systemic disease by selective utilization or modification of I-A-bearing cells.

Abstract
Reovirus type 1, known to be a cause of systemic and intestinal disease in mice, is secreted into the bile of adult A/J mice after viremia. Virus found in the bile in concentrations higher than those in blood may indicate that reovirus type 1 is actively transported into the bile. The transport of virus was independent of levels of virus-specific immunoglobulin A antibody. Modifications of the virus that occurred during transport did not discernibly affect the infectivity of the virus. Entry of virus into the bile may be an important mechanism by which an enteric virus that produces systemic disease reenters the intestine for transmission.

Abstract
It is well known that endogenous sulfhydryls are radioprotective in mammalian cells. Their comparable role in chemotherapeutic drug toxicity has been known for almost as long but less well defined. Thiol depletion as a mechanism responsible for enhanced cytotoxicity of melphalan was assayed by pretreatment of cells in vitro with misonidazole and buthionine sulfoximine (BSO). Hypoxic cell sensitizers, such as MISO, deplete endogenous thiols by metabolic activation under hypoxic conditions to thiol reactive intermediates, whereas BSO specifically inhibits a key enzyme in the synthesis of glutathione. For a given level of thiol reduction, sensitization to melphalan was far greater by preincubation with MISO than it was for BSO. This indicated that thiol reduction itself was not the sole factor involved in chemosensitization by MISO. As evidence that the method of thiol depletion predisposes to the expression of biological damage, it was shown that cells preincubated with MISO were appreciably more vulnerable to oxidative stress than those exposed to BSO. BSO was shown to totally inhibit the repair of damage from a preincubation treatment with MISO, demonstrating that recovery is dependent upon thiol regeneration. Thiol depletion "per se" is a good qualitative but not necessarily a quantitative indicator of chemosensitization--the biological and biochemical function of the thiol depleting agents used influences further drug interactions. The results of the study with these two agents suggest that thiols may play a potentially more critical role in the repair rather than the initiation of drug-induced damage.
