The plasma-membrane potential (Delta(psi)p) in bloodstream forms of Trypanosoma brucei was studied using several different radiolabelled probes: 86Rb+ and [14C]SCN- were used to report Delta(psi)p directly because they distribute in easily measured quantities across the plasma membrane only, and [3H]methyltriphenylphosphonium

We investigated the effects of ischemia on the kinetics and control of mitochondria isolated from normal and ischemic heart. The dependence of the respiratory chain, phosphorylation system and proton leak on the mitochondrial membrane potential were measured in mitochondria from

Membrane potential across the plasma membrane (psi) of human sperm was determined by measuring the accumulation of triphenylmethylphosphonium (TPMP+). Washed sperm of fertile or infertile men were suspended, incubated in low-K+ and high-Na+ or high-K+ and low-Na+ medium, and allowed

Analysis of the atp operon from the thermoalkaliphilic Bacillus sp. TA2.A1 and comparison with other atp operons from alkaliphilic bacteria reveals the presence of a conserved lysine residue at position 180 (Bacillus sp. TA2.A1 numbering) within the a subunit of

Mitochondrial-targeted antioxidants that selectively block mitochondrial oxidative damage and prevent some types of cell death have been developed. These antioxidants are ubiquinone and tocopherol derivatives and are targeted to mitochondria by covalent attachment to a lipophilic triphenylphosphonium cation. Because of
