The global production of fish oil is around one million tonnes. This production is expected to be maintained. Rich in long-chain omega-3 fatty acids, especially EPA and DHA, it can supplement diets inadequate in these fatty acids such as those in many Western countries. Farmed fish, especially oily fish such as salmonids fed on fish oil provide an excellent source of these acids. Fish oil can b...

The release of fatty acids from perfused mesenteries of spontaneously hypertensive rats (SHR) and control Wistar-Kyoto rats (WKY) was studied. The release of the prostaglandin precursors dihomogammalinolenic acid, arachidonic acid, and eicosapentaenoic acid was reduced in SHR when compared with age-matched WKY. The release of all other fatty acids detected in the effluent was also reduced. The ...

Effects of a daily fish-oil supplement on serum lipids, apolipoproteins, and some platelet functions and hemorheologic variables were examined in 27 hyperlipidemic subjects in a randomized, controlled, double-blind, crossover fashion with an identically encapsulated vegetable oil serving as the control treatment. Despite the habitual high linoleic acid intake of the study population, significan...

The influence of fatty acid composition and tocopherol on cholesterol oxidation in fish, flax, sunflower, and palm oil to which cholesterol was added were examined during storage and heating. The contents of cholesterol oxides in all oils increased (p < 0.05) during storage and heating. Total cholesterol oxides in fish oil were higher (p < 0.05) than that in vegetable oils. Addition of R-tocoph...

We have shown that dietary fish oil is protective against experimentally induced colon cancer, and the protective effect is enhanced by coadministration of pectin. However, the underlying mechanisms have not been fully elucidated. We hypothesized that fish oil with butyrate, a pectin fermentation product, protects against colon cancer initiation by decreasing cell proliferation and increasing d...

BACKGROUND Vasomotor reactivity may contribute to the pathophysiology of ischemic injury. The atherosclerotic vessel may be particularly susceptible to vasoconstriction because of the damaged endothelial layer with resultant loss of vasodilatory factors. While dietary omega 3 fatty acids have been proposed to protect against vascular occlusion, it is not clear to what extent this results from a...

the purpose of this study is to produce an oil-in-water nano-emulsion by ultrasonication. casein combined with inulin used as continuous phase, while dispersed phase consisted of fish oil. the size of the nano-emulsion and the ph of nano-emulsion were characterized. ultrasound has been used for preparing emulsion by 24 khz intensity for 120 seconds. prepared nano-emulsion was investigated by pa...

Phospholipase C catalyzes the hydrolysis of the sn-3 phosphate head group in phospholipids including phosphatidylcholine, phosphatidyletanolamine, and phosphatidylserine with the formation of 1,2-diacylglycerol and water soluble phosphate esters phosphorylcholine, phosphorylethanolamine, and phosphorylserine. Phospholipase C from P. pastoris is intended for use in the refining of soybean oil an...

this study was designed to determine the effects of dietary replacement of fish oil with canola oil ongrowth performance, feed efficiency of body and economic indices of experimental diets of juvenilecommon carp (cyprinus carpio). during the experiment 270 juvenile fish with an average initialweight of 16.24 ± 0.10g were randomly distributed in 18 well aerated cylindrical polyethylene tanks(15 ...

The effects of dietary supplementation with fat of different fatty acid profile and chronic intermittent hypoxia (CIH) on the fatty acid composition of serum and heart lipids were analysed. Adult male Wistar rats were fed a standard non-fat diet enriched with 10 % of lard, fish oil (n-3 PUFA) or maize oil (n-6 PUFA) for 10 weeks. After 4 weeks on the diets, each group was divided in two subgrou...
