There is evidence to indicate that the high rates of coronary heart disease and myocardial infarction amongst Indians of Asian descent may be partly related to circulating nonesterified fatty acids (NEFA). As docosahexaenoic acid (DHA,22:6n-3) in NEFA form has been found to exhibit anti-platelet aggregatory and anti-arrhythmic potential in vitro, the effect of supplementary DHA was examined in ...

The fasting concentration of non-esterified fatty acids (NEFA) and the degree to which it declines during an oral glucose tolerance test are closely associated with insulin resistance and glucose intolerance. However, relatively few studies have described possible environmental determinants of NEFA concentrations. Physical activity is likely to be related to NEFA levels, but habitual activity l...

Low density lipoproteins (LDL) were modified in vitro in the presence of lipid transfer activity and lipolysis, which induced alterations in the size and lipid composition of LDL particles but not in their antioxidant content. Subsequently, modified LDL were oxidized with copper sulfate and the extent of LDL oxidation was evaluated. Lipid transfer activity alone, or in combination with lipolysi...

In this study concentration and composition of non-esterified fatty acids (NEFA) in follicular fluid (FF) of high-yielding dairy cows were determined during the period of negative energy balance (NEB) early post partum. NEFA were then added during in vitro maturation at concentrations measured previously in FF to evaluate their effect on the oocyte's developmental competence. At 16 and 44 days ...

The objective was to study the effects of abomasal infusion of linseed oil, a source rich in n-3 C18:3, on whole-body response to insulin (experiment 1) and on insulin antilipolytic effects during feed restriction (experiment 2). In experiment 1, eight nonlactating, non-gestating cows were assigned to a crossover design, fed to meet maintenance requirements, and infused abomasally with either l...

Although exerting valuable functions in living organisms, nonesterified fatty acids (NEFAs) can be toxic to cells. Increased blood concentration of oleic acid (OLA) and other fatty acids is detected in many pathological conditions. In sepsis and leptospirosis, high plasma levels of NEFA and low albumin concentrations are correlated to the disease severity. Surprisingly, 24 h after intravenous o...

Elevation of plasma nonesterified fatty acid (NEFA) levels has been shown in various studies to induce peripheral tissue insulin resistance and impair the suppression of endogenous glucose production (EGP). These studies have been conducted predominantly in men. We compared the effects of elevated plasma NEFA levels on basal and insulin-stimulated glucose metabolism in 8 normal women (age 42 +/...

The aim of the study was to investigate the improving effect of Garcinia cambogia extract on performance metrics, and serum non-esterified fatty acids (NEFA) and C-reactive protein (CRP) levels in rats fed with atherogenic diet. Thirty, one-year-old, female Sprague-Dawley rats were randomly assigned to threeexperimental groups of ten animals each. Control group was fed with basal diet (2% liqui...

Background: The Lori-Bakhtiari sheep breed is one of the most common native breed in the south-western parts of Iran. The peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. OBJECTIVES: This study was carried out to compare the serum concentrations of glucose, non-esterified f...
