The work reviews membrane processes, such as monooxygenase reaction and oxidative phosphorylation with special reference to hydroxylation of a xenobiotic benzo(a)pyrene and the effects of the radical scavenger propyl gallate and radical generator Fe2+ ions on the reaction kinetics. A possibility is discussed that tocopherol provides for the activit...

The synthesis of phosphatidylcholine (PC) in rod outer segments (ROS) catalysed by lysophosphatidylcholine acyltransferase and phosphatidylethanolamine N-methyltransferase (PE N-MTase) was studied and the effects of natural (FA and lysophospholipids) and synthetic (Triton X-100, deoxycholate and CHAPS) surfactants was evaluated. In all experimental...

The kinetic and concentration dependences of erythrocyte vesiculation and hemolysis induced by sodium dodecyl sulfate were studied. The similarity of the slopes of the dose dependence of the SDS-induced vesiculation and slow hemolysis rates in the double logarithmic coordinates suggested a close relation between the processes of vesiculation and po...

The dynamics of structural changes of the chondriome in the early development of the sea urchin Paracentrotus lividus was studied. Mature eggs and embryos at various stages of cleavage were used for quantitative and ultrastructural analysis based on computerized 3D reconstruction from serial ultrathin sections. The following structural transformati...

Liposomes made from phosphatidylcholine (PC) or PC-fatty acid ester mixtures have been shown to induce an activation of the respiratory burst in human blood monocytes and alveolar macrophages (AM). Incorporation of 1,2-diacylglycerol or arachidonic acid into PC liposomes significantly enhanced the effect. In the case of AM, the effect of PC liposom...

The behaviour of epitheliocytes, their transformed analogues, and fibroblasts was studied on special culture substrates--lattices with large square openings (the area of an opening was 2000 microm2). It was shown that normal epithelocytes and fibroblasts initially attached to and spread on the lattice bars, were soon displaced into the lattice open...

Reliability of the hydropathy method to predict the formation of membrane-spanning alpha-helices by integral membrane proteins and peptides whose structure is known from X-ray crystallography is analysed. It is shown that Kyte-Doolittle hydropathy plots do not predict accurately 22 transmembrane alpha-helices in the reaction centres (RC) of the pho...

Monolayers of seven fractions of natural lipids (phosphatidyl inositol, sulfoquinovosyl diacylglycerol, phosphatidylcholine, digalactosyl diacylglycerol, phosphatidyl glycerol, phosphatidylethanolamine, monogalactosyl diacylglycerol), isolated from the photoautotrophic cell culture of the moss Marchantia polymorpha grown under normal and light-stre...

ATP-dependent K+ (K(ATP)) channel was purified from the inner mitochondrial membrane and reconstituted into the bilayer lipid membrane. The K(ATP) activity was inhibited by high concentrations of ATP and ADP, but was activated by low concentrations (up to 200 microM) of ADP. p-Diethylaminoethyl benzoate (DEB) acted as a K(ATP) opener: at micromolar...

The data on the structure, functions, and classification of lamins, the main protein components of nuclear lamina, are reviewed. The participation of lamina in the rearrangements of the nuclear membrane during cell division is considered in detail. The recent data on the organization of interphase chromatin and its interaction with the nuclear peri...
