background: prepubertal varicocele has the most devastating effects on the testes. oxidative stress is the major cause leading to infertility in varicocele. the antioxidant properties of flaxseed (fs) treatment in some oxidative diseases have been reported. objective: this study aimed to evaluate the antioxidant effect of fs in prepubertal rats with experimental varicocele. materials and method...
introduction: acrylamide (acr) known as a neurotoxic agent in human and animals. previous studies have been shown; fasudil improves neurological deficit and neuronal damage. in this study, the effect of fasudil, potent rho-kinase inhibitor, on acr-induced cytotoxicity was evaluated using pc12 cells as a suitable in vitro model. materials and methods: pc12 cells were exposed to different concent...
conclusions hemodialysis exacerbates oxidative stress and conformational changes of hb in patients with diabetes on hemodialysis. the frap value can be used as a positive determinant, while pco and hb derivatives can be used as negative determinants of oxidative stress in patients with diabetes. background diabetes is associated with an increased generation of reactive oxygen species (ros), whi...
objective: hexavalent chromium [cr (vi)] compounds are well-known environmental contaminants generated from industrial processes. several studies have reported the harmful effects of cr (vi) on different organs, however, little is known about neurotoxic effects of cr (vi). the aim of this study is to investigate the toxic effects of cr (vi) on pc12 cells. methods: pc12 cells were cultured foll...
Postoperative cognitive decline (POCD) is a common complication following anesthesia and surgery, especially in elderly patients; however, the precise mechanisms of POCD remain unclear. Here, we investigated whether nicotinamide adenine dinucleotide phosphate (NADPH) oxidase mediated-abnormalities in parvalbumin (PV) interneurons play an important role in the pathophysiology of POCD. The animal...
Resuscitation and prolonged ventilation using 100% oxygen after cardiac arrest is standard clinical practice despite evidence from animal models indicating that neurologic outcome is improved using normoxic compared with hyperoxic resuscitation. This study tested the hypothesis that normoxic ventilation during the first hour after cardiac arrest in dogs protects against prelethal oxidative stre...
OBJECTIVE To investigate the pretreatment effects of Rhodiola rosea (R. rosea) extract on cognitive dysfunction, oxidative stress in hippocampus and hippocampal neuron injury in a rat model of Alzheimer's disease (AD). METHODS Male Sprague-Dawley rats were pretreated with R. rosea extract at doses of 1.5, 3.0, and 6.0 g/kg for 3 weeks, followed by bilateral intracerebroventricular injection w...
Palmitate concentrations in type 2 diabetic patients are higher than in healthy subjects. The prolonged elevation of plasma palmitate levels induces oxidative stress and mitochondrial dysfunction in neuronal cells. In this study, we examined the role of mdivi-1, a selective inhibitor of mitochondrial fission protein dynamin-regulated protein 1 (Drp1), on the survival of cultured hippocampal neu...
Diabetes mellitus has been reported to affect functions of the hippocampus. We hypothesized that Centella asiatica, a herb traditionally being used to improve memory, prevents diabetes-related hippocampal dysfunction. Therefore, the aim of this study was to investigate the protective role of C. asiatica on the hippocampus in diabetes. Methods. Streptozotocin- (STZ-) induced adult male diabetic ...
Chronic hyperglycemia increases oxidative stress status and has been associated with neurological complications in diabetic individuals. This study compared the antioxidant properties of red wine or resveratrol in different brain areas of diabetic and non-diabetic rats, and investigated the effect of them on hippocampal cell proliferation in hippocampal dentate gyrus of diabetic rats. Streptozo...
