the purpose of this study was to determine the effect of two levels of four commercial multi-enzymes on the apparent metabolizable energy corrected for nitrogen (amen) and digestibility of crude fat, crude protein, dry matter, and organic matter in broiler chickens through total excreta collection method. one hundred thirty male broiler chicks were assigned to 45 metabolic cages involving 9 tre...

the objectives of this study were to determinethe interactions between two hepatic enzymes and some minerals in the liver of broiler chickens. the study was performed with male and female from 1 to 56 days of age of broiler chickens. malic acid was added to the water and offered to chickens freely from the start to the end of the experiment with constant concentration. the treatments consisted ...

Background: Polycystic ovary syndrome (PCOS) is one the most common diseases in women fertility age. PCOS alters ovarian follicles and affects blood lipid profiles, liver enzymes hormones. In this study, we tried to investigate effects of coenzyme Q10 (CoQ10) on pathological conditions. Methods: Twenty-four female rats were randomly divided into three groups; 1: control group, 2: group (receive...

Two main periods can be considered in the history of fish metabolism under pressure. The first period (roughly from 1870 to 1970) was mainly descriptive: survival times and behavior were studied and some authors described an increase in oxygen consumption under pressure; later, the counteracting effects of high temperature on pressure were mentioned. The second period (from 1970 onwards) was mo...

objective: the study was conducted to evaluate cardioprotective effect of silk cocoon (abresham) bombyx mori (b. mori) on isoprenaline-induced myocardial infarction. this study deals with the cocoons, which is called abresham in the unani system of medicine. it is one of the 64 drugs which avicenna has mentioned in avicenna’s tract on cardiac drugs and used in the treatment of cardiovascular di...

Accurate protein function prediction is an important subject in bioinformatics, especially wheresequentially and structurally similar proteins have different functions. Malate dehydrogenaseand L-lactate dehydrogenase are two evolutionary related enzymes, which exist in a widevariety of organisms. These enzymes are sequentially and structurally similar and sharecommon active site residues, spati...

Miller and Baumann (3) and Giese, Miller and Baumann (1) studied the carcinogenicity of various methyl derivatives of dimethylaminoazobenzene and found that the m'-methyl-p-dimethylaminoazobenzene was the most potent of the azo dyes for the production of liver tumors in rats, being even more active than ~-dimethylaminoazobenzene itself. As we were interested in studying conditions of rapid carc...
