Algae oil and fish oil are n-3 PUFA mainstream commercial products. The various sources for the stability of n-3 PUFA oxidation are influenced by the fatty acid composition, extraction and refined processing. In this study, the oil stability index (OSI) occurs within 2.3 to 7.6 hours with three different n-3 PUFA rich oil. To set the OSI in the Rancimat test as the oil stability limit and observed various degrees of oxidation (0, 25, 50, 75, 100 and 125%). The volatile oxidation compounds were analyzed via headspace-solid phase microextraction (HS-SPME) and GC/MS...

The obese insulin resistant and/or prediabetic state is characterised by systemic lipid overflow, mainly driven by an impaired lipid buffering capacity of adipose tissue, and an impaired capacity of skeletal muscle to increase fat oxidation upon increased supply. This leads to the accumulation of bioactive lipid metabolites in skeletal muscle interfering with insulin sensitivity via various mechanisms. In this review, the contribution of dietary v. endogenous fatty acids to lipid overflow, their extraction or uptake by skeletal muscle as well as the fractional synthetic rate, content and composition of the muscle lipid pools is discussed in relation to the development or presence of insulin resistance and/or an impaired glucose metabolism...

Dietary fatty acids (FA) act as signaling molecules with diverse effects on physiologic function. The aim of this article is to review and summarize the clinical human studies in the literature on how dietary FA composition in meals and diets affects hunger and satiety signaling in the body. Studies examining FA saturation (monounsaturated (MUFA), saturated or polyunsaturated (PUFA) FAs) or FA chain length from high-fat meals/diets were included. Measures of appetite included visual analog scale (VAS) questionnaires, appetite hormones (Cholecystokinin (CCK), glucagon-like peptide-1 (GLP-1), peptide YY (PYY), gastric insulinotropic polypeptide gastric inhibitory peptide (GIP), ghrelin, leptin, insulin) and/or energy intake (EI) data...

Fish starvation is defined as food deprivation for a long period of time, such that physiological processes become confined to basal metabolism. Starvation provides insights in physiological processes without interference from unknown factors in digestion and nutrient absorption occurring in fed state. Juveniles of amberjack Seriola lalandi were isotopically equilibrated to a formulated diet for 60 days. One treatment consisted of fish that continued to be fed and fish in the other treatment were not fed for 35 days...

BACKGROUND: Docosahexaenoic acid (DHA) is a major dietary n-3 polyunsaturated fatty acid (n-3 PUFA) in fish oil, and has been reported to possess a number of biological properties, such as anti-inflammatory, antitumor and immune-regulatory properties. However, whether DHA exert anti-inflammatory effect on lipopolysaccharide (LPS)-induced mastitis remains unclear. In this study, we investigate the effect and underlying mechanisms of the effects of DHA on LPS-stimulated primary bovine mammary epithelial cells (bMEC)...

Rabbitfish Siganus canaliculatus is the first marine teleost reported to have the ability of biosynthesizing C20-22 long-chain polyunsaturated fatty acids (LC-PUFA) from C18 precursors, and thus provides us a model for studying the regulatory mechanisms of LC-PUFA biosynthesis in teleosts. To investigate the possible roles of peroxisome proliferator-activated receptors (PPARs), critical transcription factors involved in the regulation of lipid metabolism, in the regulation of LC-PUFA biosynthesis in rabbitfish, the PPAR genes were cloned and their expression characterization with PPAR agonists, dietary lipid resource, and ambient salinity were examined...

Inspissated bile syndrome (IBS) is a rare condition in which thick intraluminal bile, including bile plugs, sludge, or stones, blocks the extrahepatic bile ducts in an infant. A 5-week-old female infant was admitted for evaluation of jaundice and acholic stool. Diagnostic tests, including ultrasound sonography, magnetic resonance cholangiopancreatography, and a hepatobiliary scan, were not conclusive. Although the diagnosis was unclear, the clinical and laboratory findings improved gradually on administration of urodeoxycholic acid and lipid emulsion containing omega-3 polyunsaturated fatty acids (PUFAs) for 3 weeks...

Metabolic changes occur in patients with peroxisomal diseases owing to impairments in the genes involved in peroxisome function. For diagnostic purposes, saturated very-long-chain fatty acids (VLCFAs) such as C24:0 and C26:0, phytanic acid, pristanic acid, and plasmalogens are often measured as metabolic hallmarks. As the direct pathology of peroxisomal disease is yet to be fully elucidated, we sought to explore the fatty acid species that accumulate in patients with peroxisomal diseases. We developed a method for detecting a range of fatty acids implicated in peroxisomal diseases such as Zellweger syndrome (ZS) and X-linked adrenoleukodystrophy (X-ALD)...

Branched chain fatty acids (BCFA) are components of common food fats and are major constituents of the normal term human newborn GI tract. Polyunsaturated fatty acids (PUFA) have been suggested to reduce the risk and development of inflammatory bowel diseases (IBD); however, little is known about the influence of BCFA on inflammation. We investigated the effect of BCFA on interleukin (IL)-8 and NF-κB production in a human intestinal epithelial cell line (Caco-2). Cells were pre-treated with specific BCFA, or DHA, or EPA, and then activated with lipopolysaccharide (LPS)...
