This work aimed to evaluate Roundup effects on biochemical biomarkers of the neotropical fish Prochilodus lineatus. Fish were acutely exposed (6, 24 and 96 h) to 10 mg L(-1) of Roundup (RD) or only water (control) and samples of liver, for antioxidants analysis, and brain and muscle, for acetylcholinesterase (AChE) determination, were collected. Fish exposed to RD for 24h showed reduction on su...

Supplementation has beneficial effects in immune system and can antioxidant enzymes activity increases during the exercise and protects the tissue against the oxidative stress. L-Carnitine is a famous Supplement and helps to protect against the oxidative stress during and after intense or prolonged exercise. The aim of this study was to investigate the effect of L-Carnitine supplementation on t...

Little is known about the potential effects of glyphosate on freshwater gastropods and possible interactions between other stressors. A two-way factorial experiment was conducted to investigate temperature (20 °C/25 °C) (0 µg/L/200 µg/L) Lymnaea sp. After 21 days, antioxidant capacity (superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) glutathione-S-transferase (GST)), mal...

The aim of this study was to compare the organismal responses farmed and wild-caught turbot, Scophthalmus maximus, based on analyses biochemical plasma parameters, leukocyte profile, histological tissue profile gills, kidney, liver, intestine, spleen, as well gene expression stress proteins in kidney liver tissue. results revealed significant differences triglycerides (TRIG), total protein (TP)...

AIM This study was conducted to evaluate the impact of hot dry, hot humid and comfortable season on physiological, hematological, biochemical, and oxidative stress parameters in Surti buffaloes. MATERIALS AND METHODS Ten lactating Surti buffaloes of similar physiological status were selected. Based on the temperature-humidity index (THI), their natural exposure to the environment was categori...

 The effect of sodium silicate (Si) and potassium (K) were investigated on the major antioxidant enzyme activities in two different grapevine cultivars (Vitis vinifera L., cvs Yezandai and Malinger Ramfi) under drought stress. The traits included superoxide dismutase (SOD, EC 1.15.1.1), catalase (CAT, EC 1.11.1.6), peroxidase (POD, EC 1.11.1.7), guaiacol peroxidase (GPX, EC 1.11.1.7), ascorbate...

Selenium may play a beneficial role in multi-factorial illnesses with genetic and environmental linkages via epigenetic regulation in part via glutathione peroxidase (GPx) activity. A meta-analysis was undertaken to quantify the effects of dietary selenium supplementation on the activity of overall GPx activity in different tissues and animal species and to compare the effectiveness of differen...

BACKGROUND We investigated the relationship of the immunohistochemical expression status of manganese superoxide dismutase (MnSOD), catalase, glutathione peroxidase (GPx), and myeloperoxidase (MPO) in buccal mucosal squamous cell carcinoma (SCC) with clinicopathologic parameters and prognosis. METHODS The expression status of MnSOD, GPx, catalase, and MPO was evaluated by immunohistochemistry...

Epididymal glutathione peroxidase (GPX) has been suggested as a major factor in combating loss of fertility of spermatozoa due to lipid peroxidation. We report here the isolation and sequence of putative GPX cDNAs from rat (Rattus rattus) and cynomolgus-monkey (Macaca fascicularis) epididymis, which exhibit marked sequence identity with known GPXs. In both species the cDNAs encode predicted pre...

BACKGROUND We have recently demonstrated that activity of red blood cell glutathione peroxidase-1 is inversely associated with the risk of cardiovascular events in patients with coronary artery disease. The present study analyzed the effect of glutathione peroxidase-1 deficiency on atherogenesis in the apolipoprotein E-deficient mouse. METHODS AND RESULTS Female apolipoprotein E-deficient mic...
