Fatty liver is a major health problem worldwide. People with hereditary deficiency of hormone-sensitive lipase (HSL) are reported to develop fatty liver. In this study, systemic and tissue-specific HSL-deficient mice were used as models to explore the underlying mechanism of this association. We found that systemic HSL deficient mice developed fatty liver in an age-dependent fashion between 3 a...

The phospholipids, particularly phosphatidylethanolamine, of brain gray matter are enriched with docosahexaenoic acid (22:6n-3). The importance of uptake of preformed 22:6n-3 from plasma compared with synthesis from the alpha-linolenic acid (18:3n-3) precursor in brain is not known. Deficiency of 18:3n-3 results in a compensatory increase in the n-6 docosapentaenoic acid (22:5n-6) in brain, whi...

Healthy pregnant women (n 23) were supplemented with fish-oil capsules (2.7 g n-3 polyunsaturated fatty acids/d) from the 30th week of gestation until delivery. Subjects in a control group were either supplemented with olive-oil capsules (4 g/d, n 6) or received no supplementation (n 10). Fatty acid compositions of the phospholipids isolated from umbilical plasma and umbilical arterial and veno...

a 42-day study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (srbc). a total of 324 one-day-old chicks were attributed to 6 experimental groups. c: control (soybean-corn); cs1:7.5% cs; cs2:15% cs; cs-fs:10% fs + 10% cs; fs1:...

Despite an abundance of literature describing the basic mechanisms of action of L-carnitine metabolism, there remains some uncertainty regarding the effects of oral L-carnitine supplementation on in vivo fatty acid oxidation in normal subjects under normal conditions. It is well known that L-carnitine normalizes the metabolism of long-chain fatty acids in cases of carnitine deficiency. However,...

Essential fatty acid (EFA) deficiency exerts a beneficial effect on immune-mediated glomerulonephritis, preventing both the tissue injury and consequent mortality. Because both macrophages and eicosanoids are thought to play pathogenic roles in glomerulonephritis, and because macrophages play an important role in modulating arachidonate metabolism at sites of renal injury, the effects of EFA de...

BACKGROUND The clinical manifestations of inherited disorders of fatty acid oxidation vary according to the enzymatic defect. They may present as isolated cardiomyopathy, sudden death, progressive skeletal myopathy, or hepatic failure. Arrhythmia is an unusual presenting symptom of fatty acid oxidation deficiencies. METHODS AND RESULTS Over a period of 25 years, 107 patients were diagnosed wi...

  In this study changes in fatty acids profile during frozen storage at -18°C of Cobia (Rachycentron canadum), caught from the Persian Gulf (Bandar Abbas) were studied. Changes in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), EPA+DHA/C16, n-3 PUFA/n-6 PUFA (n-3/n-6) and polyunsaturated fatty acids /saturated fatty acids (PUFA/SFA) were i...
