INTRODUCTION We investigated the effects of ghrelin on protein expression of the liver antioxidant enzymes superoxide dismutases (SODs), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR), nuclear factor κB (NFκB) and inducible nitric oxide synthase (iNOS). Furthermore, we aimed to investigate whether extracellular regulated protein kinase (ERK1/2) and protein kinase B...

welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

Objective: Aerobic training and berberine chloride include antioxidant characteristics. In this study, aerobic training and berberine chloride intervention on the activity of antioxidant enzymes and lipid peroxidation of pancreatic tissue were investigated in type 1 diabetic male wistar rats. Materials and Methods: In the current study, 56 Wistar male rats were randomly assigned to seven diffe...

This work was designed to evaluate whether external application of nitric oxide (NO) in the form of its donor S-nitroso-N-acetylpenicillamine (SNAP) could mitigate the deleterious effects of NaCl stress on chickpea (Cicer arietinum L.) plants. SNAP (50 μM) was applied to chickpea plants grown under non-saline and saline conditions (50 and 100 mM NaCl). Salt stress inhibited growth and biomass y...

Trifolium alexandrinum is traditionally used in various human ailments, including renal dysfunctions. The present experiment was designed to investigate antioxidant and nephroprotective effect of T. alexandrinum methanolic extract (TAME) against CCl4-induced oxidative stress in albino rats. Results of in vitro study revealed significant (P < 0.05) antioxidant effects. The ameliorative role of T...

Peroxisomes are single membrane cell organelles with a diversity of metabolic functions. Here we studied the peroxisomal dysfunction and oxidative stress after 3-nitropropionic acid (3-NP) induced neurotoxicity and the possible protective effects of oxytocin. Adult male and female rats were subjected to Oxt and/or 3-NP treatment. The antioxidant enzymes, Superoxide dismutase (SOD) and Catalase ...

The use of soil additives such as selenium can positively influence the antioxidative system plants, making them more tolerant to abiotic stresses. aim this work was evaluate concentration sodium selenite or selenate applied substrate that causes improve in plant growth and enzyme activities sunflower plants. treatments were divided in: control (absence selenium); 0.2 mg L-1 selenate; 0.4 0.8 s...

Purpose The main aim of this study was investigate the association between the genetic polymorphism of antioxidant enzyme genes: SOD1, CAT and GSHPX1 and the risk of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis in the Polish population. Methods A total of 445 subjects including 200 patients with IBD and 245 controls were allowed in this study. We determin...

The stimulation of oxidative stress and lipid peroxidation of liver tissues by AFB1 has been extensively investigated. However, the effect of AFB1 on antioxidant enzyme activities and gene expression in testis has not been completely elucidated. The current study investigated the histopathological picture and activities in addition to gene expression of antioxidant enzymes in testis of rats int...
