Ca2+ binding and membrane fluidity in essential and renal hypertension.
1. Ca2+ -binding ability and membrane structure of red blood cells of patients with essential and renal hypertension were studied. 2. Ca2+ -binding ability of the erythrocyte membrane of patients with essential hypertension was found to be reduced by 30% compared with that of normotensive controls. 3. The rate of lateral diffusion of pyrene in the erythrocyte membrane of patients with essential...
متن کاملDesmosterol and Membrane Fluidity
Previous spin-label and electromyographic experiments with rats fed 20,25-diazacholesterol, an inhibitor of the biosynthet ic conversion of desmostero[ to cholesterol, demonstrated an increased e ry th rocy te membrane f luidi ty and myotonia, a prolonged muscle contraction upon stimulation. The current studies with rats showed normal erythrocyte f luidi ty in animals fed 20,25-diazacholesterol...

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...
متن کاملLipid fluidity and membrane protein dynamics.
Membrane fluidity plays an important role in cellular functions. Membrane proteins are mobile in the lipid fluid environment; lateral diffusion of membrane proteins is slower than expected by theory, due to both the effect of protein crowding in the membrane and to constraints from the aqueous matrix. A major aspect of diffusion is in macromolecular associations: reduction of dimensionality for...
متن کاملMembrane Fluidity in Human and Mouse
An increased membrane fluidity was also detected with a spin label that probes deeper in the bilayer. In vitro treatment of Chediak-Higashi mouse cells with 0.01 M ascorbate increased the order parameter to normal levels. In vitro incubation of mouse Chediak-Higashi cells with glucose oxidase increased the order parameter, similar to the effect of ascorbate. This increase was abolished when cat...
