Posttranslational modification of proteins by the small molecule ubiquitin is a key regulatory event, and the enzymes catalyzing these modifications have been the focus of many studies. Deubiquitinating enzymes, which mediate the removal and processing of ubiquitin, may be functionally as important but are less well understood. Here, we present an inventory of the deubiquitinating enzymes encod...

the effect of long-term onion consumption on red blood cell antioxidant enzymes [glucose-6-phosphate dehydrogenase (g6pd), superoxide dismutase (sod) and glutathione peroxidase (gpx)], were measured. the relationship of these enzymes with pcv and hemoglobin (hb) concentrations was also determined. twelve adult female goats were used for the experiment and randomly assigned to three groups. anim...

background: methyl 2-benzimidazole carbamate (carbendazim) is a synthetic fungicide used against organisms that cause different types of plant diseases. it is widely used as a preservative in leather, paint, textile, fruit, and paper industry. it is also used as an anticancer drug in clinical medicine. methods: to evaluate the low dose toxicity of this compound in mammalian tissues, carbendazim...

The value of dietary exogenous enzymes in promoting growth and efficiency of feed utilization is well recognized in poultry industry. In a case of high-cost yellow corn, several feed producers are choosing to replace yellow corn with other ingredients that have lower nutritional value like triticale, wheat, barley or sorghum. These crops are rich in non-starch polysaccharides (NSPs), and there ...

an experiment was conducted to evaluate the effects of supplementing black cumin (nigella sativa) seeds (bcs) in diet on performance, liver weight and enzymes of broilers.the experiment was conducted as a randomized complete block design. two hundred forty day-old unsexed broiler chicks (cobb 500) were divided into four groups and assigned to four feeding treatments, with four replicates of 15 ...

this study was aimed to evaluate the effect of gnrh injection on semen ejaculate characteristics in awassi rams collected in breeding and non breeding seasons. the study was conducted in late summer to early autumn when breeding activity commences, and in winter during the non breeding season. twelve mature awassi rams were used in this study. animals were randomly allocated into two equal grou...

background and aims: artichoke (cynara scolymus l.) is a plant of the asteraceae family. this plant is used in herbal medicine. this study was conducted to evaluate the effect of artichokeextract on insulin, glucagon, glucose, alkaline phosphatase (alp), alanine amino transferase (alt) and aspartate amino transferase (ast) in streptozotocin-induced diabetic rats. methods: in this experimental s...

background: the aim of this study was to evaluate the possible protective effect of sodium selenite on serum, liver, and kidney antioxidant enzymes activities in alloxan-induced type 1 diabetic rats. methods: forty sprague-dawley male rats were randomly divided into four groups; group one as control, group two as sham-treated with sodium selenite by 1 mg/kg intraperitoneal (i.p.) injections dai...

background :  pathogenic bacteria because of beta-lactam antibiotic resistance genes are dangerous to society. this resistance due to esbl genes, plasmids and transposons that by receiving or mutation occurs. the most important factor beta-lactam antibiotic resistance is beta lactamase enzymes. the purpose of this study was to evaluate the frequency of hospital opportunistic pathogenic bacteria...
