during storage, serum separation is a major defect that affects the market share of doogh. therefore, in the present study the effects of high shear stirring and homogenization, as major operation units, on the stability was investigated. to do so, dooghs were stirred at various speeds and time scales (9000 rpm and 11000 rpm for 30 s and 2 min), homogenized at different pressures (0, 20, 50, 80...

A hydrogenase linked to the carbon monoxide oxidation pathway in Rubrivivax gelatinosus displays tolerance to O2. When either whole-cell or membrane-free partially purified hydrogenase was stirred in full air (21% O2, 79% N2), its H2 evolution activity exhibited a half-life of 20 or 6 h, respectively, as determined by an anaerobic assay using reduced methyl viologen. When the partially purified...

A series of micro-mesoporous zeolitic catalysts synthesized using recrystallization two different zeolites (HZSM-5 and beta) were impregnated with Pt other notable metals. The resulting bifunctional characterized tested for the hydrocracking a model municipal waste plastic mixture. Actual mixture same composition was also employed comparison. experiments carried out in Parr stirred batch reacto...

Famotidine is generally employed for the treatment of gastric ulcer. The present study was conducted to fabricate famotidine tablets using various diluents. The binder was incorporated to the formulations in different proportions. Both the dry granulation and direct compression techniques were employed to develop the tablets. Physical evaluation of tablets i.e. tablets hardness, friability, wei...

Determination of benzophenones (BPs) in human urine samples by stir bar sorptive extraction (SBSE) and thermal desorption (TD)-gas chromatography-mass spectrometry (GC-MS) is described. As analytes, BP, its metabolites benzhydrol (BP-OH) and 2-hydroxybenzophenone (2OH-BP), and its derivatives 2-hydroxy-4-methoxybenzophenone (BP-3) and 2-hydroxy-4-methoxy-4'-methylbenzophenone (BP-10) were selec...

UDP-glucuronosyltransferases (UGTs) are critical for the metabolism and clearance of drugs, chemicals, and hormones. The development of UGT1A1 and 1A6 was studied in 50 pediatric liver samples using bilirubin, serotonin activity assays, and Western blot as well as pharmacokinetic scaling. UGT activity developed age dependently in pediatric liver. Maximal activity of 0.7690 nmol · min · (-1) mg ...
