Serum concentrations of non-esterified fatty acids (NEFA) and very low-density lipoprotein (VLDL) in close-up dairy cattle were compared in relation to parity. Data were obtained from 37 nulli/primiparous (NP) and 24 multiparous (MU, parity: 2-7) cows between 14 days and 1 day prepartum. A positive correlation (r=0.684, P<0.01) was found between serum NEFA and VLDL concentrations in NP cows. Am...

NEFA, also known as free fatty acids (FFA), are the form in which stored body fat is transported from adipose tissue to its sites of utilization (Fig. 1). Their importance was recognized in the 1950s once methods became available for their reliable measurement in plasma. Because of the rapid turnover of plasma NEFA, they constitute a large proportion of the ‘energy flux’ through the bloodstream...

INTRODUCTION Cardiorespiratory fitness (CRF) is an independent predictor of voluminous health outcomes and can be measured using non-exercise fitness assessment (NEFA) equations. However, the accuracy of such equations in Asian populations is unknown. The objective of this study was to cross-validate the NEFA equation, developed by Jurca et al in 2005, in the adult Singaporean population. MET...

The aim of this study was to investigate the effects of different levels of forage and concentrates diets on the metabolism of glucose, β-hydroxybutyrate (BOHB) and nonesterified fatty acid (NEFA) in livers of nonlactating goats. Six catheterized GuanZhong goats (40±2 kg weight) were fed high concentrate diet (HC, 40% hay, 60% concentrate) or high forage diets (HF, 60% hay, 40% concentrate). Bl...

BACKGROUND Although nonesterified fatty acids (NEFA) have been positively associated with coronary heart disease risk factors, limited and inconsistent data are available on the relation between NEFA and sudden cardiac death. METHODS AND RESULTS Using a prospective design, we studied 4657 older men and women (mean age, 75 years) from the Cardiovascular Health Study (1992-2006) to evaluate the...

1. Intravenous infusions of lipid-free albumin were used to lower the arterial non-esterified fatty acids (NEFA)/albumin ratio during coronary occlusion in dogs. 2. Reduction of the NEFA/albumin ratio was accompanied by proportionate reductions in myocardical uptake of NEFA and the degree of ST segment elevation in epicardial electrocardiographic recordings from the ischaemic zone. Aortic press...

fatty liver is a metabolic disorder of dairy cows in early lactation, and approximately half of multi-parous dairy cows experience a moderate to severe fatty liver at calving. since the occurrence of fatty liver in buffalo is not known, the aim of this study was to evaluate the hepatic content of triacylglycerols (tag) and total lipids (tl), and the serum content of non-esterified fatty acids (...

The integration of lipid metabolism in the splanchnic bed and in subcutaneous adipose tissue before and after ingestion of a 75 g glucose load was studied by Fick's principle in seven healthy subjects. Six additional subjects were studied during a hyperinsulinemic euglycemic clamp. Release of non-esterified fatty acids (NEFA) from adipose tissue and splanchnic NEFA extraction followed a similar...
