The interaction of cyclodextrins (CDs) with L-alpha-dipalmitoyl phopsatidyl choline (DPPC), L-alpha-distearoyl phosphatidyl choline (DSPC), and L-alpha-dimyristoyl phosphatidyl choline (DMPC) unilamellar liposomes was investigated by the leakage of carboxylfluorescein (CF) entrapped in the inner
The present study evaluated the influence of phospholipids (phosphatidyl choline and phosphatidyl inositol) on the prevention of abdominal biomaterial-associated infection. Phospholipid-impregnated silicone elastomer (SE) fragments were either intraperitoneally implanted in rats or immersed in serum
The immunolocalization of phospholipids has not yet been clearly demonstrated in temporomandibular joints (TMJs). We have examined the distribution of one of phospholipids, phosphatidyl-choline (PC), in the rat mandibular condylar surface and lower joint cavity. Some fresh resected TMJs with their
Adult mice have two easily recognizable subsets of B cells: the predominant resting population of the spleen, called B-2, and those called B-1, which predominate in coelomic cavities and can express CD5. Some antibody specificities appear to be unique to the B-1 population. Cells expressing antibody
The ability of interphotoreceptor retinoid-binding protein (IRBP) to facilitate the incorporation of retinol into retinyl esters by the retinal pigment epithelium (RPE) was examined in toad (Bufo marinus) eyecup preparations devoid of neural retina (RPE-eyecup). Solutions containing purified bovine
A phase I and II clinical trial of intraperitoneally administered liposome-encapsulated doxorubicin in patients with advanced ovarian cancer is being evaluated. Doxyrubicin liposomes were prepared with cardiolipin, phosphatidyl choline, cholesterol, and sterarylamine and sized by flow cytometry
Auxin-induced pea (Pisum sativum) stem section elongation is enhanced at levels of 3 to 40 micromolar by six new classes of alkane derivatives additional to those described earlier, providing that length of their molecules exceeds 20 A. Increasingly longer homologous series of alkyl chlorides,
Cuminum cyminum, an aromatic plant from the family Umbelliferae, is used as a flavoring and seasoning agent in foods. This communication reports the characterization of a nonspecific lipid transfer protein nsLTP1 from its seeds. Plant nsLTPs are small basic proteins involved in transport of lipids
Besides various gastroduodenal diseases, Helicobacter pylori infection may be involved in autoimmune disorders like rheumatoid arthritis (RA) or idiopathic thrombocytopenic purpura. Such autoimmune disorders are often associated with autoreactive antibodies produced by B-1 cells, a subpopulation of
