In this study, effect of different levels of dietary protein (25, 35 and 45 per cent) and water salinity (0-3, 12-15 and 32-35 ppt) on antioxidant enzymes of white leg shrimp (Penaeus vannamei) was studied. 324 P.vannamei (with mean weight±SE: 5.55 ± 0.18 gr) were randomly distributed in twenty seven tanks. Experimental shrimps were fed by formulated diets for 56 days and at the end of the expe...

BACKGROUND: Cancer cachexia is the progressive loss of skeletal muscle protein that contributes significantly to cancer morbidity and mortality. Evidence of antioxidant attenuation and the presence of oxidised proteins in patients with cancer cachexia indicate a role for oxidative stress. The level of oxidative stress in tissues is determined by an imbalance between reactive oxygen species prod...

background: diazinon (dzn) is an organophosphate pesticide that widely used for agricultural pest control all over the world. dzn affects target organs including reproductive system by inhibiting the activity of acetylcholinesterase and inducing oxidative stress. vitamin e (α-tocopherol) is a strong antioxidant which inhibits free radicals, and probably can reduce lipid perxidation effectively ...

the present study was designed to investigate the immunomodulatory activity of the ethanolic extract of tinospora cordifolia (family: menispermaceae)stem (climbing shrub, mango plant) at cellular level. for antioxidant study, the liver mitochondria were separated and the concentration of enzymes like lipid peroxidation (lpo), reduced glutathione (gsh), catalase (cat) and superoxide dismutase (s...

The present study was designed to explore the relationship between lipid peroxidation and antioxidant enzymes in young Malaysian insulin dependant diabetes mellitus (IDDM) patients. Indicative parameters of lipid peroxidation, activities of antioxidant enzymes and diabetes parameters were evaluated in single blood samples from 30 young type 1 diabetic patients and 30 healthy control subjects. A...

The present study aims to assess the toxic effect of latex and ethanolic leaf extract of Calotropis procera (C. procera), in comparison to abamectin, on serum biomarkers of function and histological integrity of heart and testis in male albino rats. To achieve this aim, the albino rats were separately administered 1/20 and 1/10 of LD50 of C. procera latex, ethanolic C. procera leaf extract and ...

Nandrolone, 19-nortestosterone, is a synthetic androgenic-anabolic steroid promoting muscle growth. Nandrolone is also present in pig meat and sera at non-negligible levels. A number of scientific reports have suggested a positive relationship between incidence of infertility and increased meat consumption in humans. The present study was designed to determine out the effect of feeding nandrolo...

Commercial pectolytic enzymes were investigated for their influence on phenolics and antioxidant activities of asparagus juice. The antioxidant activity of asparagus juice was analyzed according to 2,2'-diphenyl-l-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) methods. The enzymes, with the exception of pectinase from Rhizopus sp., contained rutinase, which hydrolyzed ...

The adaptive response of the genome protection mechanism occurs in cells when exposed to genotoxic stress due to the overproduction of free radicals via inflammation and infection. In such circumstances, cells attempt to maintain health via several genome protection mechanisms. However, evidence is increasing that this adaptive response may have deleterious effect; a reduction of antioxidant en...
