The effect of aminoguanidine on sperm motility and mitochondrial membrane potential in varicocelized rats
Objective(s): Increased levels of nitric oxide (NO) in the testicular veins of people suffering from varicocele have already been reported. However, the role of NO-synthase (NOS) isozymes and their inhibitors have not been extensively studied. We aimed to evaluate the inhibitory effects of aminoguanidine (AG), on sperm motility, vitality, and mitochondrial membrane potential (MMP) in varicoceli...
متن کاملMitochondrial K(ATP) channel activation reduces anoxic injury by restoring mitochondrial membrane potential.
Mitochondrial membrane potential (DeltaPsi(m)) is severely compromised in the myocardium after ischemia-reperfusion and triggers apoptotic events leading to cell demise. This study tests the hypothesis that mitochondrial ATP-sensitive K(+) (mitoK(ATP)) channel activation prevents the collapse of DeltaPsi(m) in myocytes during anoxia-reoxygenation (A-R) and is responsible for cell protection via...
متن کاملSodium and Potassium Fluxes and Membrane Potential of Human Neutrophils
Sodium and potassium ion contents and fluxes of isolated resting human peripheral polymorphonuclear leukocytes were measured . In cells kept at 37 °C, [Na]i was 25 mM and [K]i was 120 mM; both ions were completely exchangeable with extracellular isotopes . One-way Na and K fluxes, measured with 22Na and 42K, were all -0.9 meq/liter cell water -min . Ouabain had no effect on Na influx or K efflu...
متن کاملUranyl Acetate Induces Oxidative Stress and Mitochondrial Membrane potential collapse in the Human Dermal Fibroblast Primary Cells
Cytotoxicity of depleted uranium, as a byproduct of military has been came to spotlight in recent decades. DU is known as a chemical rather than radioactive hazard and efforts to illustrating its mechanism is undergo, but the precise complete molecular mechanisms are still unclear. Recent studies showed that uranium induces biological changes in many different target tissues, such as the kid...
