Effect of non-esterified fatty acids on insulin resistance and cardiovascular risk in polycystic ovary syndrome
… The effect of non-esterified fatty acids (NEFA) on IR, postprandial lipids and cardiovascular risk in obese women with PCOS compared to controls was examined by lowering NEFA levels with acute overnight acipimox and chronic 12 week tredaptive therapy. Additional studies included elevating …

The Association Between Non-Esterified Fatty Acids And Beta-Hydroxybutyrate During The Transition Period In Holstein Dairy Cows And Negative Downstream Outcomes - Disease Incidence, Milk Production And Reproduction
… and milk production. Non-esterified fatty acids (NEFA) and betahydroxybutyrate (BHBA) are measurable blood metabolites used to estimate the level of NEB. The objectives of herein were to: 1) identify critical concentrations of NEFA and BHBA above which the development of diseases were more likely; …

Subsequent milk production and metabolic response of first-calf heifers fed whole raw soybeans during the last trimester of gestation
… (+35 d) was used to evaluate glucose and NEFA response to diet. Glucose concentration in blood plasma at -69 d and 0 d was lower in heifers fed WSB; whereas, plasma NEFA concentration was greater at -69 d, -48 d, and +35 d, but lower at 0d. Basal concentrations of glucose and NEFA in …

The effect of selection for milk yield on net energy balance and plasma concentrations of endogenous hormones and metabolites in primiparous Holsteins
… prolactin (PRL), nonesterified fatty acids (NEFA) and glucose was studied in primiparous Holstein cows. Net energy balance was calculated and serial blood samples were collected at 0, 45, 90, 180 d postpartum (dpp) and 14 d of the dry period over a 7 h period via jugular cannulae. After 2.5 h …

Effect of dry period diets varying in energy density on health and performance of periparturient dairy cows: a study of dry matter intake, lactation performance, fertility, blood parameters and liver condition
… samples. Glucose, BHB (β- hydroxybutyrate), NEFA (Non-esteriffied fatty acids), GLDH (Glutamate dehydrogenase), AST (Aspartat aminotransferase), GGT (Gamma glutamyl transferase), ICDH (Isocitrate dehydrogenase) were analyzed from blood and liver fat was estimated under a microscope. Ketolac® …

Mitochondrial Involvement in Pancreatic Beta Cell Glucolipotoxicity
… glucose and non-esterified free fatty acid (NEFA) levels can cause pancreatic β-cell failure. The molecular mechanisms of this β-cell glucolipotoxicity are yet to be established conclusively. In this thesis by exploring mitochondrial energy metabolism in INS-1E insulinoma cells and isolated …

Effects of close-up dietary energy strategy and prepartal dietary monensin on production and metabolism in Holstein cows
… of M. Cows that were fed CE had greater NEFA concentrations prepartum (P < 0.01) but lower NEFA postpartum (P = 0.05). The inclusion of M during the DP did not affect prepartum or postpartum NEFA and BHBA concentrations. Concentrations of total lipid, triglyceride, and glycogen in liver …

Biochemical markers of hypertension and chronic renal failure in a Gulf Arab population of the United Arab Emirates
… (TG), non-esterified fatty acids (NEFA) and ET-1 and lower high-density lipoprotein- (HDL)-cholesterol. Further, both SBP and DBP weresignificantly correlated with age, BMI. NEFA, ET-1 and log insulin and TG and negatively with HDL-cho!esterol. The independence of associations …

Hormones, Metabolites, and Reproduction in Holsteins, Jerseys, and their crosses
… reproduction, progesterone (P4), IGF-I, insulin, NEFA, and milk production differed between genetic groups. Thirty-five cows were Holstein-Jersey (HJ) crosses, 48 were Jersey-Holstein (JH) crosses, 51 were Holsteins (HH), and 29 were Jerseys (JJ). Days open (DO) was affected by genetic group. HH …

Effects Of Food Deprivation On Blood Lipid Concentration And Composition In Steller Sea Lions (eumetopias Jubatus)
… of plasma non-esterified fatty acids (NEFA) were analyzed spectrophotometrically. Serum fatty acid composition was analyzed using gas chromatography (GC) and their individual weight percent (wt %) were correlated with their peak retention time and calculated using the area under each …

The impact of carbohydrate ingestion on the regulation of fat oxidation following exercise
… increased (pc0.05) non-esterified fatty acid (NEFA) levels. CHO ingestion led to a dramatic increase in glucose and insulin levels and a drop in NEFA levels (p<0.05). The phosphorytataion of acety bCoA carboxylase (ACC), 5'AMP-activated protein klnase (AMPK) and hormone sensitive lipase (HSL) …

Akuteffekte des polyphenolreichen unlöslichen Carobballaststoffes auf Parameter des Metabolischen Syndroms bei gesunden Erwachsenen
… von Insulin und nicht-veresterten Fettsäuren (NEFA) im Mittelpunkt der Betrachtungen. Der Verzehr des Carobballaststoffes in Kombination mit 200 ml Wasser und 50 g Glukose erhöhte die postprandialen Glukose- und Insulinkonzentrationen gegenüber der Glukoselösung ohne Ballaststoffzusatz. In …

Influence of body weight gain on insulin regulation, adipose tissue inflammation and lipid metabolism in equines
… A (SAA), insulin, non-esterified fatty acids (NEFA) and triglycerides were measured in serum. Levels of inflammatory parameters (CD68, IL-1β, IL-6, TNFα) and markers of lipid metabolism (FABP4, LPL) were analyzed in AT samples by RT-qPCR. The project was approved by the Ethics Committee for …

Characterization of coconut oil and CLA induced lipolysis
… was determined by non-esterified fatty acid (NEFA) and glycerol release in 3hr ex vivo cultures. BFI was reduced by CO on d7 (P<0.01) and CLA tended (P=0.09) to decrease BFI in CO-fed mice on d10. BFI was reduced in both CO and SO-fed mice (P<0.05) in response to CLA on d14. NEFA release was …

Data mining and mathematical modelling on diabetes
… the contribution of non-esterified fatty acid (NEFA) metabolism, which is an important source of energy for the body. Also, significant interactions exist among NEFA, glucose, and insulin. It is important to consider these metabolic interactions in order to characterize the endogenous energy …

Effects of prenatal testosterone treatment on growth performance and carcass characteristics of cattle and sheep
… lambs, respectively. Non-esterified fatty acid (NEFA) concentrations were 41.3% greater (P $<$.05) in P ewe lambs.

Relationships among nutritional regimen, metabolic disorders, reproduction, and production in dairy cows during the transition period
… FO period had lower nonesterified fatty acids (NEFA) concentrations in wk 1, 2, and 3 of lactation compared with cows fed HE. Higher NEFA concentration in wk 1 postpartum was associated with a greater probability of diseases (n = 251; OR = 1.176). Cows on the CE regimen during the FO period had …

Differential effects of fatty acids on the endothelium
… DHA decreased plasma non-esterified fatty acids (NEFA) compared to placebo. The in vitro investigations suggested that the composition of circulating NEFA may differentially affect endothelial function in the microvasculature. Conclusion: Dietary EPA and DHA at relatively high doses do not improve …

Metabolic and endocrine adaptations to heat stress in lactating dairy cows
… and decreased plasma non-esterified fatty acid (NEFA) in lactating cow, the opposite responses typical of PF cohorts. Therefore, the present studies were performed in order to elucidate the mechanism(s) underlying these counterintuitive changes. In response to a glucose tolerance test (GTT), both …
