in order to study the effects of salicylic acid and selenium application on yield and yield components of rainfed wheat cultivars, a field experimental was carried out as factorial based on randomized complete block design with four replications in the research station of islamic azad university- arak branch, iran in 2010-2011 growing season. the treatments were salicylic acid and selenium. sal...

Abstract The supplementation of Selenium-enriched probiotics is effective in reducing oxidative stress and maintaining meat quality stability broiler chicken especially under heat stress. An experimental study was conducted to perform Comparative analysis Selenium yeast with inorganic Se broilers A total 120 chicks one day were assigned 4 groups each consisting 30 fed on same basal diet but dif...

Selenium is a fundamental importance to human health. It is an essential trace element for major metabolic pathways, since selenium is an essential component of glutathione peroxidase enzyme. Diet is the main source of selenium. Selenoproteins in mammalian cells indicated that essential role of selenium in the body’s antioxidant defense system.

Selenium is a key component of many important enzyme systems, including the glutathione peroxidase (GPX) family of enzymes. Glutathione peroxidases are primarily involved in repairing cell membranes damaged by lipid peroxidation caused by reactive oxygen species. The glutathione peroxidases may also have an anti-inflammatory role. Sepsis is known to cause a significant degree of oxidative stres...

Selenium concentration in the brain tissue is far less variable than those in peripherals, such as the liver and kidneys, in rodents, when fed a selenium-deficient diet. This fact implies the importance of this element for maintaining the integrity of brain functions and the distinctive selenium metabolism and/or the regulatory mechanism in the brain. To obtain basic information concerning the ...

UNLABELLED We investigated the changes in oxidative stress in platelets from surgical patients anesthetized with propofol. We studied 60 surgical patients (ASA physical status I and II) and 12 healthy volunteers. The patients were divided into three groups: anesthesia induced with an IV bolus dose of 4 mg/kg thiopental; anesthesia induced with an IV bolus dose of 2 mg/kg propofol; and total IV ...

This study pertains to the role of selenium against the toxic manifestations of chronic cadmium exposure. The kidney is a recognized target organ for chronic cadmium exposure, owing to the very long half-life of cadmium. Cadmium (as cadmium chloride) in a dose of 8 mg kg-1 body wt. was administered orally for a period of 8 weeks in mice. This resulted in a significant decrease in total reduced ...

Ascorbic acid and selenium are two nutrients that seem to have a preventive potential in the process of carcinogenesis; because of a possible synergistic action that may produce an enhanced anticarcinogenic effect. Interaction between these nutrients have been reported. Results indicate that the protective effect of the inorganic form of selenium (Na Selenite) was nullified by ascorbic acid, wh...

Glutathione peroxidase-3 (Gpx3), also known as plasma or extracellular glutathione peroxidase, is a selenoprotein secreted primarily by kidney proximal convoluted tubule cells. In this study Gpx3(-/-) mice have been produced and immunocytochemical techniques have been developed to investigate Gpx3 metabolism. Gpx3(-/-) mice maintained the same whole-body content and urinary excretion of seleniu...

Effect of occupation on haematological factors, lipid peroxidation and antioxidants' status was studied in masons and compared with normal subjects. Red blood corpuscles (RBC), haemoglobin (Hb), Vitamin C, Vitamin E, beta-carotene levels and glutathione peroxidase (GSHPx), superoxide dismutase (SOD) and catalase (CAT) activities decreased. Thiobarbituric acid reacting substances (TBARS) level i...
