Bovine aortic endothelial cells in culture have been incubated with human low density lipoproteins (LDL) characterized in their cholesterol content. The incubation was done at different time intervals up to 72 h and various LDL concentrations. It began after endothelial cells had been starved for 24 h in lipoprotein deficient serum. The transfer of some(More)
The effect of some membrane ligands on the plasmalemmal fluidity of endothelial cells from bovine aorta in culture was investigated. The ligands used were: cationic ferritin (pI 8.5), soybean agglutinin, concanavalin A, wheat germ agglutinin, as well as glutaraldehyde at different concentrations. The fluidity probe employed was 1,6-diphenyl-1, 3,(More)
The microfluidity of cell membranes has been modified experimentally in endothelial cells and smooth muscle cells of bovine or monkey aorta cultured in vitro. Microfluidity was estimated by fluorescence depolarization measurements of diphenyl-hexatriene (DPH)-labelled cells. In both types of cells investigated, the arachidonic acid at concentration of 90(More)
The synthesis of diaqua(1,10-phenanthroline-N,N')(thiosulfato-O,S)manganese(ll) [Mn(phen)(S(2)O(3))(H(2)O)(2)] was investigated. Its structure was determined by single crystal X-ray diffraction from 2418 reflections (I > 3 sigma(I)) to a final value of R = 0.047 and Rw = 0.054. Crystal data are as follows : space group P(2) (1); a = 10.356(3), b = 7.097(3),(More)
