Sleep deprivation by the disk-over-water technique results in a predictable syndrome of physiological changes in rats. It has been proposed that reactive oxygen species (ROS) may be responsible for some of these effects. A variety of antioxidative enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx) help to regulate the level of ROS. In this study we investigated the effe...

INTRODUCTION Oxidative stress and antioxidants play an important role in the pathogenesis of inflammatory disease, including chronic periodontitis (CP). Saliva contains enzymatic (glutathione peroxidase - GPx, superoxide dismutase - SOD, etc.) and non-enzymatic (albumin - ALB, uric acid - UA, glutathione, etc.) antioxidants. OBJECTIVE The aims of this study were to investigate: a) level of SO...

Iron nanoparticles (Fe NPs) have a wide array of biological and medical applications. In agriculture, Fe NPs has the potential to be used as an innovative technique alleviate deficiency in various crops, such grape. However, effect on alleviating stresses grapevine are unexplored. The aim this study was evaluate efficiency protecting ‘Asgari’ seedless grape (Vitis vinifera L.) against oxidative...

The antioxidant potential of foods plays a vital role in counteracting oxidative stress and its consequences the body. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) are primary line defence against cellular damage caused by reactive oxygen species (ROS). Glutathione is considered to be most for body because changes during increase risk CVD. dietary capacity supporting...

Numerous experimental and clinical analyses of biomechanical injury have served to elucidate the pathophysiologic events involved in Traumatic Brain Injury(TBI).Secondary insults activate the release of cellular mediators including proinflammatory cytokines,prostaglandins, free radicals,and complement.The resulting cascade of events avalanche into free radical induced oxidative damage to the br...

the present study aimed to evaluate the protective effect of crocin on gastric mucosal lesions caused by ischemia-reperfusion (i/r) injury in rats.forty male rats were randomly divided into sham, control (i/r injury) and three crocin-pretreated groups. to induce i/r lesions, the celiac artery was clamped for 30 min and then the clamp was removed to allow reperfusion for 3 h. pretreated-rats rec...

Oxidative stress is common in several human and veterinary conditions it associated to alteration of the glutathione peroxidase (GPx) level. GPx an enzyme present erythrocytes, kidney, liver has a role protecting against oxidative damage. In this randomised double-blinded control trial on healthy dogs, we findings indicating that administration for total 35 days supplement containing S-acetyl-g...

Reproductive failure is regarded as a problem in the breeding of beef cattle indicated by low calving rate, conception longer periods interval, and neonatal mortality. Selenium deficiency may lead to non-infectious reproduction disorder ruminants. The purpose this review evaluate role selenium preventing cattle. In process, required for cellular respiration, oxidation, DNA RNA replication, inte...
