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...

background: acne vulgaris is a chronic inflammatory disease of the pilosebaceous follicles and one of the most common skin diseases.the peeling method has been recently found to be effective for acne treatment. this study aimed to compare the efficacy of pyruvic acid 50% and salicylic acid 30% peeling in the treatment of mild to moderate acne. materials and methods: in a prospective single?blin...

Cereal Chem. 71(6):582-587 Commercial corn starches containing 0-70% amylose were extruded formation of complexes between amylose and lipids. Maximum binding with and without various lipids (myristic, stearic, and behenic acids; monowas observed for myristic acid and 70% amylose starch. No binding was glyceride Dimodan PV; and tristearin) in a single-screw laboratory observed with tristearin. P...

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...
