1,2-Diselenolane-3-pentanoic acid, in which the sulfur atoms of alpha-lipoic acid are replaced with selenium, displayed markedly different antioxidant properties when compared to alpha-lipoic acid. 1,2-Diselenolane-3-pentanoic acid was unable to inhi

Halocins H6 and H4 are bacteriocin-like substances capable of killing sensitive halobacterial cells by affecting the bioenergetic steady state across the membrane. The effect of either halocin on living cells is similar, but the primary target of eac

Due to the difficulty in quantitative treatment of the three thermodynamic parameters involved in the Na+/H+-exchange process (the concentration differences of H+ and Na+ across the membrane (ΔpH and ΔpNa)) and the membrane potential (ΔΨ)), an ac

A liquid scintillation counting method for simultaneous determination of three radioactive nuclides ( 3 H, 14 C, and 22 Na) of biological interest was studied. By comparing the β spectra of the three nuclides, their counting energy ranges, A, B, and

Low oxygen tension, a high content of reducing equivalents and endogenous vitamin E are responsible for the resistance of cancer cells to oxidative stress-based therapy. N,N'-bis(2-hydroperoxy-2-methoxyethyl)-1,4,5,8-naphthalene-tetra- carboxylic-dii

Na + H + exchange activity was solubilized from Halobacterium halobium with octyl-β-D-glucoside (OG) and was reconstituted into the bacteriorhodopsin incorporated liposomes (BR-liposomes) by the detergent-dialysis method. Light illumination stimulat

We have previously shown that anacardic acid has an uncoupling effect on oxidative phosphorylation in rat liver mitochondria using succinate as a substrate (Life Sci. 66 (2000) 229-234). In the present study, for clarification of the physicochemical

A new enzymatic method for the determination of protein-bound lipoic acid was established. Bound lipoyl groups were liberated in the form of lipoyllysine by protease digestion and assayed by lipoamide dehydrogenase (NADH:lipoamide oxidoreductase, EC

The superoxide scavenging activity of dihydrolipoic acid and its analogues has been reevaluated by a chemiluminescence method using MCLA as a superoxide indicator. The results demonstrated that all the compounds having the thiol chromophore in the mo
