Sensitive micro determination of nonesterified fatty acids
Microchemical Journal, 1972Abstract A procedure is described in which an extremely sensitive copper ligand, TETD, is used as a substitute for DDC in the indirect determination of NEFA. The latter was isolated by extraction into chloroform as a copper soap followed by reaction between TETD and the copper in acid solution.

Cellular Transport of Nonesterified Fatty Acids
Journal of Molecular Neuroscience, 2001Transport of nonesterified fatty acids (NEFA) is an important component of whole-body energy metabolism, and derangements in NEFA transport have been linked to several diseases. NEFA are transferred from their sites of production to cells in hepatic and peripheral tissues by mechanisms that are regulated in part by cell status and as determined by the ...

Nonesterified fatty acids modulate steroidogenesis in mouse Leydig cells
American Journal of Physiology-Endocrinology and Metabolism, 1989The effects of nonesterified fatty acids (NEFA) in modulating testosterone synthesis stimulated by luteinizing hormone (LH, 10 ng/sample) were investigated in isolated adult mouse Leydig cells. LH-stimulated testosterone production was inhibited by triglycerides (0-500 mg/dl, 50 mg/dl, 94% of the control and 500 mg/dl, 40%) and by a mixture of NEFA ...

The Significance of Nonesterified Fatty Acids in Plasma
Archives of Internal Medicine, 1958Recent studies have clarified some aspects of fatty acid transport. The results promise to be of clinical importance, since fat, as a major energy source and as a component of body structure, plays a central role in chronic diseases of metabolism. For example, obesity can be conceived as an abnormal balance between the total amount of fatty acid stored

Accumulation of nonesterified fatty acids in ischemic canine myocardium
American Journal of Physiology-Heart and Circulatory Physiology, 1984In ischemic myocardium the time course of nonesterified fatty acid (NEFA) accumulation was studied in relation to changes in regional metabolism and mechanics. In open-chest dogs a coronary artery was partially occluded for 120 min. In the ischemic myocardium no increase was observed in NEFA content within 10 min, whereas changes were found in ...

Plasma nonesterified fatty acids in pregnancy
American Journal of Obstetrics and Gynecology, 1960Abstract 1. The effect of various combinations of glucose and insulin on plasma NEFA concentrations were tested in normal pregnant, early puerperal, and nonpregnant subjects. 2. The responses observed in plasma NEFA were dependent upon the amount of glucose administered as well as the time of glucose loading in relation to that of insulin ...

Nonesterified fatty acids and endothelial dysfunction
International Congress Series, 2003Nonesterified fatty acids (NEFA) induce vascular effects, such as the inhibition of insulin-induced nitric oxide (NO) production. In small arteries, relaxation is largely NO-independent. We aimed to assess the effect of elevated NEFA on NO-independent vasodilation. Protocols were performed before and after 120 min of a lipid emulsion infusion.

Nonesterified fatty acids in blood pressure control and cardiovascular complications
Current Hypertension Reports, 2001The fact that cardiovascular risk factors cluster among individuals with the insulin resistance syndrome strongly suggests a common pathogenetic denominator. For many years, abnormalities of nonesterified fatty acid metabolism have been implicated in the disturbances of carbohydrate and lipid metabolism that characterize the cluster.

Assay of Serum Nonesterified Fatty Acids by Atomic Absorption Spectrophotometry
American Journal of Clinical Pathology, 1973Assay of nonesterified fatty acids in 100 μ l. of serum is described. The fatty acids are extracted with chloroform-heptane-methanol solvent, and their copper complexes are determined by atomic absorption spectrophotometry. This technic possesses the sensitivity (20 μ moles per 1.) and reliability (4.2% coefficient of variation) required for clinical ...

Nonesterified fatty acids in normal and diabetic rat sciatic nerve
Lipids, 1992AbstractAlloxan‐induced diabetes in rats results in elevated levels of nonesterified fatty acids (NEFA) in whole sciatic nerve and its endoneurium. Increases in NEFA levels are more pronounced in whole diabetic nerve (40% over control) than in its endoneurial portion (20–30%).
