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 کاملMethanol extract and fraction of Anchomanes difformis root tuber modulate liver mitochondrial membrane permeability transition pore opening in rats
Objective: Extracts of Anchomanes difformis (AD) are used in folkloric medicine to treat several diseases and infections. However, their roles in mitochondrial permeability transition pore opening are not known. Material and Methods: The viability of mitochondria isolated from Wistar rat liver used in this experiment, was assessed by monitoring their swel...
متن کاملMitochondrial and Plasma Membrane Potential Dependence
The fundamental myocellular uptake and retention mechanisms of hexakis (2-methoxyisobutyl isonitrile) technetium(I) (Tc-MIBI), a technetium-99m-based myocardial perfusion imaging agent, are unresolved. Because of the lipophilic cationic nature of Tc-MIBI, it may be distributed across biological membranes in response to transmembrane potential. To test this hypothesis, net uptake and retention o...

متن کاملMitochondrial rhodanese: membrane-bound and complexed activity.
We have proposed that phosphorylated and dephosphorylated forms of the mitochondrial sulfurtransferase, rhodanese, function as converter enzymes that interact with membrane-bound iron-sulfur centers of the electron transport chain to modulate the rate of mitochondrial respiration (Ogata, K., Dai, X., and Volini, M. (1989) J. Biol. Chem. 204, 2718-2725). In the present studies, we have explored ...
