A galactolipid lipase from primary bean (Phaseolus vulgaris) leaves has been used to partially deplete spinach chloroplast inner membranes of their galactolipids. Chloroplasts treated with the lipase in the absence of bovine serum albumin lost 91% of their monogalactosyl diglyceride, 83% of their digalactosyl diglyceride, all of their phosphatidyl choline, but none of their sulfolipid. Electron...

Abstract A suitable nutrient supply, especially of vitamins, is very significant for the deep display inherent genetic properties microorganisms. Here, using chemically defined minimal medium (MM) yeast, nicotinamide and inositol were confirmed to be more beneficial performance two industrial baker's yeasts, a conventional high-sugar-tolerant strain. Increasing or proper levels could enhance bo...

A 10% rat liver homogenate in 0.25 M sucrose-10-3 M ethylenediaminetetraacetate was fractionated into mitochondria, microsomes, and a supematant fraction. Liver mitochondria derived from rats injected with leucine-3H and with phosphate-32P or with glycerolJ4C were incubated with nonlabeled microsomes in the presence of supernatant or of sucrose-EDTA. Labeled microsomes were similarly exposed to...

Unsaturated natural and synthetic phosphatidyl cholines (PCs), when treated with tannic acid and OsO4, demonstrated a substantial increase in contrast as compared to PC treated only with OsO4. This was not observed when phosphatidyl ethanolamine (PEA) was similarly exposed to tannic acid. The increased electron density observed in the lamellar organization of the PC phospholipids was limited to...

Hemolytic anemia is a major side effect of ribavirin antiviral treatment for chronic hepatitis C. Ribavirin dose reduction may compromise the antiviral response and erythropoietin can take several weeks to alleviate anemia. The purpose of the present study was to screen potentially protective drugs against ribavirin-induced hemolytic anemia in a rabbit model, using our modified CO breath test f...

The effect of acetylcholine on the incorporation of P(32) into the individual phosphatides in slices of various structures of the nervous system has been studied. There was a marked stimulation of P(32) incorporation into phosphoinositide and phosphatidic acid, but not into phosphatidyl choline and phosphatidyl ethanolamine, in the cat stellate and celiac ganglia in vitro. Acetylcholine stimula...

As compared with other methods, our recently reported method for subcellular fractionation of human platelets improves the separation of mitochondria, alpha granules, and lysosomal enzyme activities. The relative purity of these fractions has led us to undertake the present study to compare the subcellular distribution of phospholipids, fatty acids, and platelet factor 3 (clot-promoting) activi...

The effect of castration and administration of testosterone propionate (TP) has been studied in mature monkeys in relation to prostatic and seminal vesicular lipids to castrates on prostatic and seminal vesicular lipids were studied in mature monkeys. Castration decreased prostatic total lipid, total phospholipids and total glyceride glycerols. Among neutral lipid classes only diacyl glycerol w...
