Various science researches have shown that meat of ruminants has more desirable fatty acid composition and a ratio between ω-6 and ω-3 fatty acids (lower than 4.0) because of lower content of linoleic, and a higher content of ω-3 polyunsaturated fatty acids, especially linolenic fatty acid. The aim of the present study is to examine researches about feeding modulation of the fatty acid composit...

We previously reported that docosahexaenoic acid (DHA) attenuated tumor necrosis factor (TNF)-induced apoptosis in human monocytic U937 cells (J. Nutr. 130: 1095-1101, 2000). In the present study, we examined the effects of DHA and other polyunsaturated fatty acids (PUFA) on TNF-induced necrosis, another mode of cell death, using L929 murine fibrosarcoma cells. After preincubation with PUFA con...

BACKGROUND Human milk is the optimal nutrition for infants. When breastfeeding is not possible, supplementation of infant formula with long chain polyunsaturated fatty acids appears to promote neurodevelopmental outcome and visual function. Plant oils, that are the only source of fat in most of infant formulas, do not contain specific fatty acids that are present in human and cow milk and do no...

OBJECTIVE: We investigated whether the intake of virgin olive oil or sunflower oil and performance of physical exercise (at different states) affect plasma levels of triacylglycerols, total cholesterol, and fatty acid profile in rats. METHODS: The study was carried out with six groups of male rats subjected for 8 wk to a diet based on virgin olive oil (three groups) or sunflower oil (three grou...

BACKGROUND Omega-3 polyunsaturated fatty acids (eicosapentaenoic acid and docosahexaenoic acid) from fish oil ameliorate cardiovascular diseases. However, little is known about the effects of ω-3 polyunsaturated fatty acids on cardiac fibrosis, a major cause of diastolic dysfunction and heart failure. The present study assessed the effects of ω-3 polyunsaturated fatty acids on cardiac fibrosis....

Objective. The objective of the study was to determine the composition of fatty acids in milk of Creole goats in an extensive production system in an arid region of the peninsula of Baja California and compare it to two seasons of the year (rainy and dry). Materials and methods. Sampling was conducted during the dry season (June) and after the rainy season (December) in the municipality of Como...

OBJECTIVE The effect of n-3 polyunsaturated fatty acids on the serum lipid profile in a Mexican population was evaluated. MATERIAL AND METHODS Three g of salmon oil was the daily intake during four weeks. Total cholesterol, triglycerides, low density lipoproteins, high density lipoproteins and erythrocyte fatty acid composition were analyzed. RESULTS The hypertriglyceridemic group showed a ...

1. Restriction of food to ewes bearing twin lambs showed a trend to decrease the level of omega 6 fatty acids in muscle phospholipids of the foetus though this was not significant statistically (P less than 0.05). 2. There was a significant increase in the fatty acid ratio, 20:3 omega 9:20:4 omega 6 in the twin lambs as compared with single lambs. 3. There were no symptoms of polyunsaturated fa...
