The optimal conditions for the incorporation of acetate-1-(14)C and palmitic acid-1-(14)C into platelet lipids have been described. In buffer incubations with acetate there was a sharp pH optimum at 6.8; in plasma incubations, there was a broad pH optimum between 6.8-7.4. Maximal incorporation of acetate occurred at a final concentration of 1.5 mmoles/liter. In buffer, no labeled lipids were re...

Porcine corpora lutea plasma membranes were treated with neutral lipids from hen egg yolk and a special mixture consisting of 70% neutral lipids, 20% phosphatidylcholine and 10% phosphatidylethanolamine. Membrane fluidity, as determined by fluorescence polarization of DPH, significantly increased already after 30 min of incubation of the membranes with lipids. The fluidization effect of neutral...

Objective: Dementia is the fourth most common cause of death in developed countries. The relationship between plasma lipids and cognitive function is complex and controversial. Due to the increasing life expectancy of the population, there is an urgent need to control vascular risk factors and to identify therapies to prevent and treat both cognitive impairment and dementia. Here, we reviewed t...

Lipids, in particular phospholipids, are essential components of membrane systems, and the measurement of phospholipids and cholesterol in plasma and tissues is helpful in diagnosis. Phospholipids represent about 60 to 70% of total red cell (RBC) lipids, while about 25% is free cholesterol. Lipids in RBC are present in a dynamic state of equilibrium, and the RBC have the capacity for rapid exch...

Background & Aim: Hyper lipidemy is one of the main factors in progressing cardiovascular diseases. Thymus deanensis celak and Satureja bachtiarica Bunge are medicinal herbs which are used in folklore medicine in Iran. In this research, hypolipidemic effects of essential oils of these herbs in rats fed with a fatty diet were investigated. Experimental: 40 male and femade adult rats (20 rats in ...
