amino acid dehydrogenases (l-amino acid: oxidoreductase deaminating ec 1.4.1.x) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either nad+, nadp+ or fad. these enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...

background: cellulite is the accumulation of subcutaneous fat and connective tissue in tights and buttocks. xanthines, such as aminophylline, are used as phosphodiesterase inhibitors, and are also adenosine receptor antagonists. objectives: the aim of the present study was to characterize in vitro aminophylline transdermal absorption through shed snake skin, and to investigate the absorption en...

Sodium tetraborate or borax is used as a preservative in food and it is toxic to humans depending on dosage. The target organs of borax toxicity include the central nervous system, kidney and liver, and borax can be accumulated in the blood circulation. The aim of this study was to evaluate the effect of borax on human red blood cells (RBCs) of both normal and chronic renal failure (CRF) patien...

a mild and green method has been developed for the preparation of coumarins derivatives through the one-pot reactions. in our study,various phenols and ethyl acetoacetate compound in which we used silica-supported boron sulfonic acid [sio2/b(so4h)3] as a new, highly efficient and tri-functional inorganic brønsted acid catalyst were processed under solvent-free condition and thermal. the catalys...
