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

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

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
