During cryopreservation sperm encounter oxidative stress due to higher production of ROS molecules and insufficient natural antioxidant defence system. Therefore, present study was designed identify the effects various glutathione (GSH) concentrations on Indian red jungle fowl (Gallus gallus murghi) quality fertility pre-freezing post-thaw incubation hours. Semen collected from eight cocks qual...

Industrial wastewater is of global concern due to its severe effects on the environment. Compared with municipal wastewater, industrial wastewater generally contains the high concentration of toxic or no biodegradable pollutants. In recently year, scientific showed that scallop could filtration wastewater. Therefore, it was decided to determine the mechanistic toxicity of wastewater contained N...

arsenic exposure mainly through food and water has been shown to be associated with increased incidence of numerous cancers and non-cancer harmful health. it is also used in cancer chemotherapy and treatment of several cancer types due to its apoptogenic effects in the various cancer and normal cell lines. we have already reported that liver is the storage site and important target organ in as ...

Higher temperatures lead to an increase of testicular metabolism that results in spermatic damage. Oxidative stress is the main factor responsible for testicular damage caused by heat stress. The aim of this study was to evaluate lasting effects of heat stress on ejaculated sperm and immediate or long-term effects of heat stress on epididymal sperm. We observed decrease in motility and mass mot...

In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...

Mitochondria activation factor (MAF) is a high-molecular-weight polyphenol purified from black tea that activates mitochondrial respiration. It increased the mitochondrial membrane potential and motility of sea urchin sperm, by up to 8%, to the same extent as sperm-activating peptides (SAPs) secreted by the egg. Unlike SAPs, MAF had no effect on sperm swimming behavior, suggesting that the mech...

Objective(s): The present study aims to evaluate the protective effect of the compounds isolated from Echinophora cinerea (E. cinerea) against oxidative stress and apoptosis induced by cisplatin (CIS) in PC12 cells. Materials and Methods: Six compounds were isolated as quercetrin-3-O-β-D-glucopyranoside (QUE), osthol (OST), verbenone-5-O-β-D-glycopyranoside (VER), Isoimperatorin (ISO), kaempfer...

introduction: the neuroprotective role of opioid morphine against 6-hydroxydopamineinduced cell death has been demonstrated. however, the exact mechanism(s) underlying such neuroprotection, especially the role of subtype receptors, has not yet been fully clarified. methods: here, we investigated the effects of different opioid agonists on 6-ohda-induced neurotoxicity in human neuroblastoma sh-s...

Bipolaris oryzae is a phytopathogenic fungus causing a brown spot disease in rice, and produces substance that strongly perturbs motility and membrane integrities of boar spermatozoa. The substance was isolated from the liquid culture of the fungal strain using extraction and a multi-step semi-preparative HPLC procedures. Based on the results of mass spectrometric and 2D NMR techniques, the bio...
