Total lipids of Ehrlich ascites tumor cells grown in nutrient medium supplemented with 1% bovine serum albumin instead of 15% native horse serum and rate of incorporation of [3H] acetate into total lipids are reduced, while the cholesterol content of the cells is higher than of controls grown in normal medium. The lower lipid content of cells cultured in albumin supplemented medium is explained...

A method for the simultaneous purification of plasmalogens and sphingomyelin (SM) in human erythrocytes is described. Treatment of total lipids with n-hexane/acetone (1:1 v/v) resulted in selective precipitation of SM. Both the supernatant and the precipitate fractions were incubated with a phospholipase A(1) (PLA1) from Aspergillus orizae for 3.5 h. The PLA1-treated lipids were extracted with ...

BACKGROUND/AIMS The fatty acid profile in plasma lipids contributes to the increase of plasma high sensitivity C-reactive protein (hsCRP), a marker of inflammation and predictor of cardiovascular risk. The aim of this study was to examine the relationship between specific fatty acids (FA) of serum lipids and serum hsCRP in morbidly obese woman. METHODS The study included 16 morbidly obese (me...

Throughout the Proterozoic δ(13)C values for preserved n-alkyl lipids are more positive than for syngenetic kerogen. This pattern is the inverse of biosynthetic expectations. It has been suggested that this isotopic inversion results from selective preservation of lipids from (13)C-enriched heterotrophic populations, while the bulk of kerogen derives from primary producers. Here, we formulate a...

oral supplementation with 50, 100 and 150 ?g/ml calcium chloride to the fifth stadium larvae of csr2xcsr4 biovoltine hybrid silkworm, b. mori on fat body glycogen, protein, and total lipids and haemolymph trehalose and protein have been studied. one of the four normal feeds per day was substituted with treated leaves fed to silkworms at fifth instar larvae. the controls were fed with the leaves...

BACKGROUND A potential link between increase in total cholesterol and triglycerides and clinical improvement has been observed during antipsychotic drug treatment in chronic schizophrenia patients, possibly due to drug related effects on lipid biosynthesis. We examined whether changes in serum lipids are associated with alleviation of psychosis symptoms after one year of antipsychotic drug trea...

objective(s) the purpose of the present study was to evaluate the effect of ramadan fasting and weight-lifting training on plasma volume, glucose, and lipids profile of male weight-lifter. materials and methods forty male weight-lifters were recruited and divided into 4 groups (n=10 each) and as the following groups: control (c), fasting (f), training (t) and fasting-training (f-t). the t and f...

Antiproliferative properties of lipids extracted from grain sorghum (GS) dry distiller's grain (DDG) were analyzed to determine the feasibility of developing GS coproducts as a source for human health dietary ingredients. The lipid extract of GS-DDG was delivered to human colon carcinoma (Caco-2) cells by solubilizing 0-1000 microg/mL of GS-DDG lipids in 100 microg/mL increments with micelles. ...

The response of Vibrio cholerae to low nutrient levels was determined by measuring the concentrations of lipids, carbohydrates, DNA, RNA, and proteins over a 30-day starvation period. Ultrastructural integrity was observed by transmission electron microscopy. Total lipids and carbohydrates declined rapidly within the first 7 days, while DNA and protein exhibited a more constant decline over the...
