This report describes a method for and the results of an analysis of cholesterol and phospholipids in HDL2 and HDL3 and phospholipids in VHDL (d.>L 210) of patients with cerebral thrombosis, myocardial infarction and diabetes mellitus. After precipitation and elimination of LDL (low density lipoprotein) and VLDL (very low density lipoprotein) by Na phosphotangstate (NaPhT) and MgC12 and bringin...

Dikstein and Sulman (1) reported that the treatment of the rectus abdominis muscle of Bufo viridis toad with 3.4 M (25%) acetone for 2 minutes eliminated the response of the muscle to acetylcholine (ACh), but 5 to 20 ag/ml of phospholipids such as phospha tidylserine could restore the response of the treated muscle to ACh. They also observed similar effects of phospholipids on the rabbit uterus...

BACKGROUND Long-chain polyunsaturated fatty acids (LCPUFAs) reduce T-cell activation and dampen inflammation. They might thereby counteract the neonatal immune activation and hamper normal tolerance development to harmless environmental antigens. We investigated whether fatty acid composition of cord serum phospholipids affects allergy development up to age 13 years. METHODS From a population...

Conversion of 3T3-L1 preadipocytes to fully developed adipocytes in culture under the influence of dexamethasone, 1-methyl-3-isobutyl xanthine, and insulin offers a unique system to investigate differentiation-related changes in lipid metabolism. Depending on the type of isotopic precursors ([3H2]O, 32Pi, and [1-14C]acetate) used, a 10-170-fold increase in the rate of incorporation into lipid w...

BACKGROUND More than two-thirds of women who undergo surgery for suspected ovarian neoplasm do not have cancer. Our previous results suggest phospholipids as potential biomarkers of ovarian cancer. In this study, we measured the serum levels of multiple phospholipids among women undergoing surgery for suspected ovarian cancer to identify biomarkers that better predict whether an ovarian mass is...

The efficient recovery (96.3-99.6%) of phospholipids by elution from thin-layer plates is documented. The composition of phospholipids from rabbit liver and plasma is reported.

A unidimensional thin-layer chromatography system for the separation of phospholipids has been developed. The method employs precoated plates impregnated with boric acid and is capable of resolving eight phospholipid standards, including phosphatidylinositol, phosphatidylserine, and phosphatidylglycerol. Liver, kidney, and platelet phospholipids of the rat were resolved into six major classes u...

The characterization of cardio-protective lipid bioactives from cyanobacteria, such as Spirulina spp., has rarely been investigated. In this study, neutral lipids, glycolipids, and phospholipids Irish marine cyanobacterium subsalsa, were tested for anti-inflammatory antithrombotic activities in vitro human platelets. Glycolipids inhibited strongly platelet aggregation induced by platelet-activa...

Phosphatidyl glycerol, disphosphatidyl glycerol, and phosphatidyl ethanolamine were found in all of the Thiobacillus species studied. T. thioparus possessed only these phospholipids. T. intermedius, T. neapolitanus, and T. thiooxidans contained phosphatidyl-N-monomethylethanolamine, and T. novellus lipids contained phosphatidyl-N-monomethylethanolamine, phosphatidyl-N-N-dimethylethanolamine, an...
