In the current study the plasma metabolites of silvery-black porgy (Sparidentex hasta) juveniles fed with different lipids sources were analyzed in order to bio-monitoring fish health condition. In this regard, an eight-week feeding trial was conducted using seven isonitrogenous (50%) and isolipidic (20%) experimental diets : FO, CO (canola oil), SO (sunflower oil), T (tallow), FC (fish oil + c...

Background Lipases are powerful tools for the syntheses of structured lipids (SL) which are triacylglycerols (TAG) having particular fatty acid residues at specific positions. The production of TAG with medium chain fatty acids (MCFA), in positions sn-1 and sn-3, and a long-chain fatty acid (LCFA), in the internal position, has recently increased due to its nutritional interest in applications ...

Murine thioglycollate-elicited peritoneal macrophages were cultured in the presence of a variety of fatty acids added as complexes with bovine serum albumin. All fatty acids tested were taken up readily by the cells and both neutral and phospholipid fractions were enriched with the fatty acid provided in the medium. This generated a range of cells enriched in saturated, monounsaturated or polyu...

Compared with saturated fat, n-3 long-chain PUFA-rich fish oil improves insulin sensitivity in rats. We studied whether n-3 long-chain PUFA could prevent insulin resistance induced by dexamethasone (a glucocorticoid) in healthy human volunteers. A group of eight subjects was studied twice after a 2 d dexamethasone treatment, before and after a 3-week supplementation with fish oil (providing dai...

Four Hereford steers (500 +/- 4.5 kg of BW) cannulated in the proximal duodenum were used to evaluate the effects of vegetable oil source or fish oil quantity on ruminal biohydrogenation (BH) and CLA outflow. Steers were fed 1 of 4 treatment diets in a 2 x 2 factorial arrangement of treatments (oil source: canola vs. corn oil; fish oil quantity: 0 or 1%) in a 4 x 4 Latin square design. The rema...

BACKGROUND Regular exercise and consuming long-chain n-3 fatty acids (FAs) from fish or fish oil can independently improve cardiovascular and metabolic health, but combining these lifestyle modifications may be more effective than either treatment alone. OBJECTIVE We examined the individual and combined effects of n-3 FA supplements and regular exercise on body composition and cardiovascular ...

Insulin resistance, the key defect in type 2 diabetes (T2D), is associated with a low capacity to adapt fuel oxidation to fuel availability, i.e., metabolic inflexibility. This, in turn, contributes to a further damage of insulin signaling. Effectiveness of T2D treatment depends in large part on the improvement of insulin sensitivity and metabolic adaptability of the muscle, the main site of wh...

To examine the mechanism by which fish oil protects against fat-induced insulin resistance, we studied the effects of control, fish oil, and safflower oil diets on peroxisomal content, fatty acyl-CoA, diacylglycerol, and ceramide content in rat liver and muscle. We found that, in contrast to control and safflower oil-fed rats, fish oil feeding induced a 150% increase in the abundance of peroxis...

Prolonged parenteral nutrition (PN) leads to liver damage. Recent interest has focused on the lipid component of PN. A lipid emulsion based on w-3 fatty acids decrease conjugated bilirubin. A mixed lipid emulsion derived from soybean, coconut, olive, and fish oils reverses jaundice. Here we report the reversal of cholestasis and the improvement of enteral feeding tolerance in 1 infant with inte...

OBJECTIVE Long-chain n-3 fatty acid intake in Colombia is low because fish consumption is limited. Vegetable oils with high n-3 fatty acid content are recommended, but their concentrations of trans fats were high in previous studies. Thus, regular monitoring of the fatty acid composition of vegetable oils is required. Our objective was to quantify the fatty acid composition in commercially avai...
