Increasing attention has been given recently to the role of free radicals in the pathogenesis of ulcerative colitis, since the inflamed intestine is exposed to oxidative stress generated by infiltrating macrophages and neutrophils within the lamina propia. The overall goal of this study was to evaluate whether experimental ulcerative colitis induces(More)
Most acquired immunodeficiency syndrome (AIDS) service providers are in countries with little access to scientific developments relevant to their programs. It is critical to transfer advances from the scientific arena to service providers on a global scale. Human immunodeficiency virus (HIV) prevention organizations in 78 countries were randomized to(More)
To date, no attempt has been made to study alterations occurring in the amino acid profile in chronic models of thioacetamide-induced liver cirrhosis. In this work, changes in serum amino acids and proteins in rats with thioacetamide-induced liver cirrhosis are reported, together with changes in enzyme activities in the liver and serum. Seventeen female(More)
Examined the effectiveness of an HIV intervention program among 151 adolescents ages 13 to 24 years who were randomly assigned to (a) seven sessions of 1.5 hr each (10.5 hr); (b) three sessions of 3.5 hr each (10.5 hr); or (c) a no-intervention condition. Using cognitive-behavioral intervention strategies, social skills and HIV-related beliefs, perceptions,(More)
The delivery format of an HIV prevention program that had been efficacious with youths at high risk was modified from seven relatively short sessions over a one- to two-month period to three longer sessions over a one- to two-week period. In contrast to youths in the seven-session program, no change in sexual behavior was observed among those in the(More)
The intrarectal administration of trinitrobenzene sulfonic acid in rats induces ulcerative colitis, which results in histological alterations of colonic mucosa, severe modification of the cellular antioxidant defense system, and enhanced production of inflammatory eicosanoids. This study evaluated the influence of different dietary fatty acids, i.e.,(More)
We tested the effects of several processing methods on the nutritional value of faba beans. Nutritional assessment was based on chemical analyses of legume protein content and on the digestive and metabolic utilization in rats. Protein content in Vicia faba (V. faba) was 28%, and the supply of essential amino acids, except for sulfur-containing acids, was(More)
OBJECTIVES The study evaluated the relative impact of HIV risk reduction interventions for adults with severe mental illness living in the inner city. METHODS A total of 104 chronically mentally ill men and women were interviewed to determine sexual risk behavior over the past month and to assess HIV risk-related psychological characteristics, including(More)
Youths with a homosexual orientation face different developmental challenges during adolescence than those faced by heterosexual youths or individuals who recognize their homosexual orientation later in life. We discuss the impact of "coming out," or defining a homosexual orientation, on the development and identity formation of youths who come out during(More)
An experimental animal model was used to investigate whether processing improved the nutritive utilization of phytic acid phosphorus in faba beans. Phytic acid had been considered an anti-nutritional factor because of its ability of chelate minerals and impede their absorption and because of the limited capacity of monogastric species to hydrolyze and(More)
