a total of 1695 blood samples collected from ten ethnically distinct populations of iran (turks and kurds of rezaieh, lurs, aabolis, baluchis, turks and kurds of shrvan, zoroastrians, tehranis, and kermanis) were examined for six polymorphic red cell enzyme systems, namely red cell acid phosphatase (ap), adenylate kinase (ak), phosphoglucomutase (pgm1), esteraxe d (esd), adenosine deaminase (ad...

BACKGROUND The microbial synthesis of fuels, commodity chemicals, and bioactive compounds necessitates the assemblage of multiple enzyme activities to carry out sequential chemical reactions, often via substrate channeling by means of multi-domain or multi-enzyme complexes. Engineering the controlled incorporation of enzymes in recombinant protein complexes is therefore of interest. The cellulo...

background cyclosporine a (csa)-induced hepatotoxicity could be due to a reduction in α2β1 integrin expression that may either be from the direct effect of csa itself or from reactive oxygen species (ros) overproduction. objectives in this study we aimed to identify the cellular mechanisms underlying csa-induced hepatic injury by investigating the activation patterns of the antioxidant enzymes,...

carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .control mice received similar quantities of olive oil. daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. the histologic e...

BACKGROUND Enzymes degrading plant biomass polymers are widely used in biotechnological applications. Their efficiency can be limited by non-specific interactions occurring with some chemical motifs. In particular, the lignin component is known to bind enzymes irreversibly. In order to determine interactions of enzymes with their substrates, experiments are usually performed on isolated simple ...

High fiber levels (165 g neutral detergent fibre (NDF)/kg DM) in Moringa oleifera leaf powder (MOLP) could limit its utilization as a nutraceutical source Jumbo quail diets. Pre-treating MOLP with exogenous fibrolytic multi-enzymes reduce the nutrient-encapsulating effect of non-starch polysaccharides and subsequently increase nutrient bioactive compound utilization. Thus, this study investigat...
