The influence of five pure diets of isonitrogenous and isoenergic with different ratios of Clupeidae fish oil (F) and soybean oil (S) on growth, molting and survival of narrow-clawed crayfish, Astacus leptodactylus, was evaluated during an 8-weeks trial. As soybean oil replaced with fish oil in each treatment, gently. Test diets were inclusive F0/S100, F30/S70, F50/S50, F70/S30 and F100/S0 fis...

BACKGROUND Polyunsaturated fatty acid intake favorably affects chronic inflammatory-related diseases such as cardiovascular disease; however, high intake of n-6 fatty acids may attenuate the known beneficial effects of n-3 fatty acids. METHODS AND RESULTS We investigated habitual dietary n-3 fatty acid intake and its interaction with n-6 fatty acids in relation to the plasma inflammatory mark...

AIMS Fish consumption is inversely associated with cardiovascular mortality, presumably because of n-3 fatty acids in fish. Whether the protection of n-3 fatty acids extends beyond clinical coronary disease to influence the early vascular biology of atherosclerosis remains unclear. This study determined whether circulating levels of n-3 fatty acids are associated with vascular endothelial funct...

Interest in the n-3 fatty acids began some thirty years ago from the remarkable studies in the Greenland Eskimo by the Danish scientists, Dyerberg and Bang. These Eskimos had a low prevalence of coronary heart disease despite a high fat diet because their fat contained high proportions of n-3 fatty acids. This discovery stimulated a large amount of subsequent research about n-3 fatty acids as i...

The developing brain readily incorporates dietary fatty acids, while the adult brain is refractory to changes in fatty acid composition. In order to localize the time in development when this transition occurs, chicks were fed large amounts of n-3 fatty acids from fish oil beginning at 0, 1, 2, or 3 weeks of age. Control chicks were fed a soybean oil-based diet, as were the experimental chicks ...

Abstract manganese lipoxygenase (Mn-LO) oxygenates 18:3n-3 and 18:2n-6 to bis-allylic 11S-hydroperoxy fatty acids, which are converted to 13R-hydroperoxy fatty acids. Other unsaturated C(16)-C(22) fatty acids, except 17:3n-3, are poor substrates, possibly because of ineffective enzyme activation (Mn(II)-->Mn(III)) by the produced hydroperoxides. Our aim was to determine whether unsaturated C(16...

   Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...
