Bone marrow cells, lymphocytes, lymph nodes, solid lymphoid tumors, spleen and ascites cells from mice implanted with leukemia have markedly decreased o-glycerophosphate and increased lactic dehydrogenase activities. A striking parallel between the ratio of these dehydrogenases and the progression of the leukemia was found. These data, in conjunction with related findings, suggest that the a-gl...

Soluble-protein and eight enzyme profiles obtained by polyacrylamide-gel electrophoresis were compared between Meloidogyne incognita and M. arenaria. Esterase, malate dehydrogenase, and alpha-glycerophosphate dehydrogenase patterns were distinctly characteristic for each species. Peroxidase and alpha-glycerophosphate dehydrogenase isoenzyme patterns varied when nematodes were propagated on diff...

1. A method is described for extraction and partial purification of mitochondrial l-3-glycerophosphate dehydrogenase from pig brain. 2. By the criteria that have so far been applied, the extraction and purification procedures do not modify the activity of the enzyme towards artificial electron acceptors. 3. The amounts of acid-liberatable flavine and iron in the preparation were measured. 4. A ...

The lipoteichoic acid (LTA) of the Streptococcus species DSM 8747 consists of a beta-d-galactofuranosyl diacylglycerol moiety (with different acyl groups) that is linked via 6-O to a poly(glycerophosphate) backbone; about 30% of the glycerophosphate moieties carry at 2-O hydrolytically labile d-alanyl residues. As typical LTA for this array of compounds LTA 1a was synthesized. To this end, from...

Classification and analysis of ionic lipides and glycolipides are simplified greatly when the method of Dawson (1) for deacylation is followed by paper chromatographic separation of the resultant phosphate diesters and glycosides. With radioactive lipides the radiochromatographic method provides the sensitivity and accuracy essential for studies of the metabolism of these important compounds. T...

Rat liver microsomal dihydroxyacetone phosphate acyltransferase, in contrast to the glycerophosphate acyltransferase, was found to be active at low pH (5.5), stable towards heat (55 degrees C, 15 min) and trypsin (in the absence of detergents) and was not inhibited by high concentrations of N-ethyl maleimide. Dihydroxyacetone phosphate acyltransferase is only slightly and non-competitively inhi...

Nano-structured surface and its ability to dual release of osteogenic and anti-inflammatory agents have a positive effect on the success of using titanium in orthopedic applications. For this purpose, TiO2 nanotubes (TNTs) were created via anodization method on Ti sheets and loaded by β-glycerophosphate (GP) and dexamethasone (DEX) as osteogenic and anti-inflammatory agents, respecti...
