Unwanted sexual contact on campus: a comparison of women's and men's experiences.

While sexual victimization continues to be a problem on college campuses, recent attention has been drawn to understanding gender differences in victimization rates and consequences. To date, these studies remain relatively few in number. The current study surveyed 651 male and female undergraduate students about unwanted sexual experiences during 1 academic year. Comparison of men and women revealed expected differences in incidence rates, with women reporting higher rates of unwanted contact. Within the subsample of reported victims, however, there was gender similarity in terms of the context of unwanted sexual experiences. Analyses also revealed the negative consequences of these experiences for both men and women and low rates of disclosure regardless of gender. Across the full sample of students surveyed, there were interesting gender differences in knowledge of campus support services, with women more likely to have attended a prevention program and to have indicated greater knowledge of rape crisis services.

Localization of NADPH diaphorase in the mouse uterus during the first half of pregnancy and during an artificially induced decidual cell reaction.

Uteri from non-pregnant and pregnant (Days 1-10) mice were examined for the presence of NADPH diaphorase (NADPH-d) activity by histochemical techniques. Macrophages positive for NADPH-d were observed in all uterine sections but appeared to migrate out of the implantation site and cluster in the mesometrium and interimplantation zones beginning on Day 4. NADPH-d activity was seen in the luminal and glandular epithelium and in several isolated fibers coursing through the myometrium. Many branches of the uterine artery also expressed activity, with the most intense staining in the vessels of the mesometrium. However, the most remarkable staining began on Day 6 within the primary decidual zone. When the stromal cells underwent decidualization, they began to show NADPH-d activity, with the pattern of activity matching the expanding area of decidualization. By Day 9 most of the decidual cell reaction had occurred and the mesometrial decidual staining began to decrease. However, the blood vessels and the cells surrounding the developing blood spaces continued to express activity, and heavy staining was evident within the antimesometrial decidua. No NADPH-d activity was seen in any of the trophoblast cells at any time, or in embryonic tissue, except on Day 8. NADPH-d has been used to identify nitric oxide (NO) synthase. Therefore, it may represent an NO-mediated paracrine control over decidual blood flow, myometrial quiescence, or immune response during pregnancy.
