Modulation of canine myocardial sarcolemmal membrane fluidity by amphiphilic compounds.

Amphiphilic moieties such as lysophosphoglycerides and long-chain acyl carnitines accumulate in ischemic myocardium and potentially contribute to the sequelae of myocardial ischemia. To characterize alterations in membrane molecular dynamics produced by amphiphilic compounds, highly purified preparations of canine myocardial sarcolemma were spin-labeled with paramagnetic probes (5-, 12-, or 16-...

Erythrocyte Membrane Fluidity in

his study was conducted to investigate the values of the order parameter (S) and correlation time (τc) in electron spin resonance spectra for 5-DS(doxylstearic acid) and 16-DS (doxyl-stearic acid) in old normal controls and in patients with type 2 diabetes and stroke in order to assess any association between age-related disorders and membrane fluidity. Materials and Methods: We measured the me...

Effects of Temperature and Dietary Lipids on Phospholipid Fatty Acids and Membrane Fluidity in Steinernema carpocapsae.

The phospholipid composition of Steinernema carpocapsae was studied in relation to diet and culture temperature. When reared at 18 and 27.5 C on Galleria mellonella or on an artificial diet supplemented with lard, linseed oil, or fish oil as lipid sources, nematode phospholipids contained an abundance of 20-carbon polyunsaturated fatty acids, with eicosapentaenoic acid (20:5(n - 3)) predominant...

Effect of Melittin on Phase Transition and Fluidity of a Phospholipid Model Membrane

The interaction of melittin, the major protein component of bee venom, with dimyristoyl phosphatidylcholine ( DMPC ) liposomes was investigated by Electron Spin Resonance (ESR) spectroscopy using high resolution amphiphilic spin probe perdeutero-di-t-butyl nitroxide (PDDTBN). For pure DMPC liposomes, ESR signal due to the probe dissolved in the fluid hydrophobic environment provided by the inte...
