Dietary fatty acid composition, particularly polyunsaturated fatty acids, can affect both genetic and non-genetic regulatory mechanisms of carnitine palmitoyltransferase (CPT) I, the main regulatory enzyme of mitochondrial fatty acid oxidation. We aimed to determine how these regulatory mechanisms were affected by changes in the fatty acid composition of the diet in fish. Specifically, we fed r...

Background. The characterization and evaluation of the nutritional composition lupine (Lupinus mutabilis) seeds has a long history. However, determination fatty acid profile only been carried out in few varieties. Objective. This study determined chemical oil six varieties consumed Peru. Methods. extraction from each variety was using Soxhlet method. Fatty acids, moisture, acidity index, free p...

cardiovascular disease (cvd) is the leading cause of death and disability in developed countries. atherosclerosis is the major cause of cvd, accounting for about half of the attributed deaths. cholesterol homeostasis is one of the most important factors in atherosclerosis. atp-binding cassette transporters cholesterol. omega (ω) 3 fatty acids are important ligands for regulation of abc transpor...

Due to supporting evidence that dietary patterns may have a significant role in the maintenance of good physical performance with aging, we tested whether plasma fatty acids, saturated fatty acids (SFA), and polyunsaturated (PUFA) fatty acids are cross-sectionally associated with different physical performance and predict changes in physical performance over a 3-year period. Data were from the ...

Routine use of parenteral lipid emulsions (LE) in clinical practice began in 1961, with the development of soybean oil (SO) - based LE. Although clinically safe, experimental reports indicated that SO-based LE could exert a negative influence on immunological functions. Those findings were related to its absolute and relative excess of omega-6 polyunsaturated fatty acids (PUFA) and the low amou...

One hundred ninety-two female broiler chickens were randomly distributed into 16 experimental treatments as a result of the combination of 4 levels of dietary polyunsaturated fatty acids (PUFA) (15, 34, 45, and 61 g/kg) and 4 levels of supplementation with alphatocopheryl acetate (alpha-TA) (0, 100, 200, and 400 mg/kg), to determine the modification of the amount and type of fatty acids (FA) de...

Fat and lean pig breeds show obvious differences in meat quality characteristics including the fatty acid composition of muscle. However, the molecular mechanism underlying these phenotypes differences remains unknown. This study compared meat quality traits between Lantang (a Chinese indigenous breed) and Landrace (a typical lean breed). The Lantang pigs showed higher L* values and intramuscul...

Primary hepatocytes treated with nonesterified PUFA have been used as a model for analyzing the inhibitory effects of dietary polyunsaturated fats on lipogenic gene expression. Although nonesterified fatty acids play an important signaling role in starvation, they do not completely recapitulate the mechanism of dietary fat presentation to the liver, which is delivered via chylomicron remnants. ...

This review addresses the hypothesis that polyunsaturated fatty acids (PUFA), particularly those of the (n-3) family, play pivotal roles as "fuel partitioners" in that they direct fatty acids away from triglyceride storage and toward oxidation, and that they enhance glucose flux to glycogen. In doing this, PUFA may protect against the adverse symptoms of the metabolic syndrome and reduce the ri...

Deficiency of polyunsaturated fatty acids (PUFAs) is known to induce hepatic steatosis. However, it not clearly understood which type PUFA responsible for the worsening This study observed a marked accumulation triacylglycerol and cholesterol in acid desaturase 2 knockout (FADS2−/−) mice lacking both C18 ≥ C20 PUFAs that were fed PUFA-depleted diet. Hepatic was associated with enhanced sterol r...
