A reversed-phase gradient elution, UV detection method is developed for the simultaneous determination of mono (2-ethylhexyl) phthalate [MEHP] and di (2-ethylhexyl) phthalate [DEHP] in tissue samples. The method is validated with respect to extraction recovery, inter and intra-day precision, linearity of response, detect ability, and specificity. The validated method has been successfully appli...
The rates at which the sulfhydryl groups on each chain of hemoglobin fi4 react with N-ethylmaleimide and iodoacetate have been measured. The sulfhydryl group at position 93 reacts with both alkylating agents at approximately the same rate as normal liganded hemoglobin. The sulfhydryl group at position 112, which is not available in normal hemoglobin, reacts in hemoglobin f14 and does so much mo...
Phthalates are ubiquitous endocrine-disrupting chemicals that are contaminants in food and contribute to significant dietary exposures. We examined associations between reported consumption of specific foods and beverages and first trimester urinary phthalate metabolite concentrations in 656 pregnant women within a multicenter cohort study, The Infant Development and Environment Study (TIDES), ...
The rapid synthesis of 4-aryl-2,2'-bipyridines is described leading to some previously reported compounds in good yields in addition to some new functionalized bipyridines.
SINCE Lundsgaard [1930] drew attention to the remarkably toxic nature of certain of the halogenacetic acids and their role as powerful and selective inhibitors of lactic acid formation and of alcoholic fermentation, these compounds have assumed great importance in physiology, and the numerous investigations of fundamental value to the theories of muscular contraction, tissue glycolysis and ferm...
