To provide practical feeding management guidelines preceding a stressful episode during farming practices, European sea bass juveniles (initial weight: 72.3 g) were fed for 60-days different fish meal (FM) and oil (FO) dietary levels [high (30% FM, 15% FO, FM30/FO15), intermediate (20% 7% FM20/FO7), low (10% 3% FM10/FO3)] in triplicate conditions. Fish then fasted 36 h exposed to 2-h acute crow...

the sterlet (acipenser ruthenus) is one of the species of the exotic sturgeon (acipenseridae) family in iran. this important species produces caviar every year at the lowest cost and in the shortest time. the objective of this research was to assess the effect of digestarom, as a nutritional supplement, on the growth indices and safety factors of synthetically-cultured baby sterlets (acipenser ...

The single histidine residue (His-15) in hen egg white lysozyme (EC 3.2.1.17) was chemically modified by diethyl pyrocarbonate (DEPC) to form exclusively the mono-N-carbethoxyimidazole adduct (second order rate constant of 252 +/- 16 M-1 min-1). Irreversible biscarbethoxylation of the His-15 imidazole ring by DEPC was observed when lysozyme was pretreated with 2-mercaptoethanol (2-ME), 2-ME plu...

Algebraic computing in relativity and gravitation dates back more than thirty years, but only relatively recently has hardware of sufficient power to tackle large scale calculations become commonplace. Whereas it is generally understood throughout the relativity community that there are a number of packages available, the diversity of problems that the available packages can help with is not so...

Seeking to study whether measurement of lysozyme (EC 3.2.1.17) in urine by a reliable radioimmunoassay can provide a suitable index of renal tubular function and how lysozymuria develops in temporal relation to proteinuria in diabetic nephropathy, we have compared the urinary excretion of lysozyme and beta 2-microglobulin with the 15-min excretion rate of phenolsulfonphthalein in 39 patients wi...

In the present study, the interaction between nano-TiO2 and lysozyme was investigated by the method of UV-Vis detection and fluorescence spectroscopic techniques. The thermal denaturation of lysozyme has been investigated in the presence and absence of nano-TiO2 over the temperature range (293-373) K in different buffer and pH, using temperature scanning spectrosc...

in recent years, several oconjugation protocols have been developed to improve the functional properties of the enzyme lysozyme. in this study, the optimum conditions of lysozyme – oxidized inulin conjugation and functional properties of the modified lysozyme were investigated. initially, inulin (mw about 25 kda) was oxidized by periodate to provide the reactive carbonyl groups  to attach to am...

In this study, the fermentation broth of recombinant Pichia pastoris strain ncy-2 was studied. After pretreatment, separation, and purification, lysozyme optimized using biofilm ion exchange separation. Finally, dry enzyme powder prepared by concentrating vacuum drying. The removal rate bacterial cells 99.99% when centrifuged at low temperature. optimum conditions were: transmembrane pressure 0...

Abuse liability of diazepam was examined among experienced drug users. The subjects, randomly divided into two groups, each having eight subjects, received diazepam, 15 mg intravenously (gr. 1) and 30 mg orally (gr. 2). Subjective states, drug liking, sedation and euphoria were assessed at pre-drug, 15 min, 120 min and 240 min post-drug administration. In addition, brief assessment to evaluate ...
