Felt Obligation Towards Parents in Mexican-American and Anglo-American Young Adults:

Abstract: The present study compares self-reports of felt obligation towards parents, cultural attitudes about family functioning and perceptions of family interactions in a sample of 100 Mexican-American and Anglo-American young adults. On average, Mexican-American men and women reported significantly higher levels of familism, more collectivist attitudes and more helping behavior in relationships with parents than did Anglo-Americans, while Anglo respondents reported having more contact with social systems outside the family system. Mexican-American young adults generally reported feeling significantly more obligated to avoid conflict, provide assistance and strive for self-sufficiency in their relationships with parents than did Anglo-Americans. Cultural attitudes of familism and collectivism were related to reports of felt obligation for Mexican-American respondents but not for Anglo-American respondents. Implications of results for family development theory are discussed.

Association of smoking with serum and dietary levels of antioxidants in adults: NHANES III, 1988-1994.

Abstract: OBJECTIVES: This study examined the association of smoking with serum levels and dietary intakes of antioxidants in a nationally representative sample. METHODS: This study classified 7873 apparently healthy adults aged 17 to 50 years from National Health and Nutrition Examination Survey III (NHANES III) data as nonsmokers or as smokers if their serum cotinine levels were either lower than 14 ng/mL or 14 ng/mL or greater, respectively. SUDAAN software was used for the statistical analysis. RESULTS: Smokers of both sexes had significantly (P < .001) lower serum levels of vitamin C, alpha-carotene, beta-carotene, beta-cryptoxanthin, and lutein/zeaxanthin. Reduction in the serum vitamin E, lycopene, and selenium levels in smokers was slight. Smokers also had significantly lower dietary intakes of vitamin C and beta-carotene. A significant (P < .001) inverse relation was found between serum vitamin C and beta-carotene levels and cotinine levels independent of diet effect, and a positive relation (P < .001) was found between serum levels and dietary intakes. CONCLUSIONS: Antioxidants appear to have differing declines in serum levels as a result of reduced dietary intakes and the effects of smoking.

Catalytic proton reduction with transition metal complexes of the redox-active ligand bpy2PYMe

Abstract: A new pentadentate, redox-active ligand bpy2PYMe has been synthesized and its corresponding transition metal complexes of Fe2+ (1), Co2+ (2), Ni2+ (3), Cu2+ (4), and Zn2+ (5) have been investigated for electro- and photo-catalytic proton reduction in acetonitrile and water, respectively. Under weak acid conditions, the Co complex displays catalytic onset at potentials similar to those of the ligand centered reductions in the absence of acid. Related Co complexes devoid of ligand redox activity catalyze H2 evolution under similar conditions at significantly higher overpotentials, showcasing the beneficial effect of combining ligand-centered redox activity with a redox-active Co center. Furthermore, turnover numbers as high as 1630 could be obtained under aqueous photocatalytic conditions using [Ru(bpy)3]2+ as a photosensitizer. Under those conditions catalytic hydrogen production was solely limited by photosensitizer stability. Introduction of an electron withdrawing CF3 group into the pyridine moiety of the ligand as in bpy2PYMe-CF3 renders its corresponding Co complex 6 less active for proton reduction in electro- and photocatalytic experiments. This surprising effect of ligand substitution was investigated by means of density functional theory calculations which suggest the importance of electronic communication between Co1+ and the redox-active ligand. Taken together, the results provide a path forward in the design of robust molecular catalysts in aqueous media with minimized overpotential by exploiting the synergy between redox-active metal and ligand components.
