Diets high in polyunsaturated fatty acids may protect against duodenal ulcer, possibly through inhibiting the growth of Helicobacter pylori. This hypothesis was tested in vitro by incubating H pylori microaerophilically with a range of polyunsaturated fatty acids. omega-3 Linolenic acid significantly, but reversibly, inhibited growth at 1.8, 2.5, and 5 x 10(-4) M (p < 0.01), while concentration...

Cryopreservation of seabass (Lates calcarifer) semen is an approach to increase the quantity and quality of seabass fry in aquaculture. However, cold shock can induce sperm injury leading to structural damage of the plasma membrane and loss of motility. Thus, the effect of cryopreservation on fatty acid composition and antioxidant enzyme activities of seabass sperm was determined. In cryopreser...

The importance of the plyunsaturated fatty acid in milk in the growth of nurslings needs no further mention. According to Bosworth et al.(1), arachidonic but no linoleic and linolenic acids are present in the polyunsaturated fatty acid of milk-fat. However, Hilditch et al.(2) reported that milk-fat contains linoleic acid at a level of 5%. Riemenschneider et al.(3) reported that the arachidonic ...

BACKGROUND Polyunsaturated fatty acids of the omega-6 (omega-6) class, as found in corn and safflower oils, can act as precursors for intermediates involved in the growth of mammary tumors when fed to animals, whereas polyunsaturated fatty acids of the omega-3 (omega-3) class, as found in fish oil, can inhibit these effects. The effects of dietary intervention on the ratios of these fatty acids...

Fatty acid profile of deep-sea mud shrimp (Solenocera hextii) and shovel-nosed lobsters (Thenus unimaculatus) harvested from south-west coast (Arabian Sea) India were evaluated compared. Palmitic oleic acids the principle saturated fatty monounsaturated acids, respectively in lobster species. T. unimaculatus contained greater concentrations C20-22 n-3 polyunsaturated such as docosahexaenoic eic...

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...

Three groups of Hansenula polymorpha fatty acid auxotrophic mutants were screened by their fatty acid requirement for growth. The mutants are saturated fatty acid auxotrophic mutants (Sfa), monounsaturated fatty acid auxotrophic mutants (Mfa) and polyunsaturated fatty acid auxotrophic mutants (Pfa) which required saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids...

 The study aims to determine the influence of frying (shallow and deep) with olive, canola and sunflower oil on fatty acid composition of silver carp < /font>. Frying by olive oil and canola oil increased the monounsaturated fatty acids (MUFA) significantly (p < 0.05) that consequently decreased saturated fatty acids (SFA), polyunsaturated fatty acids (PUFA) and ω-3 fatty acids. Frying by sunfl...

Murine thioglycollate-elicited peritoneal macrophages were cultured in the presence of a variety of fatty acids added as complexes with bovine serum albumin. All fatty acids tested were taken up readily by the cells and both neutral and phospholipid fractions were enriched with the fatty acid provided in the medium. This generated a range of cells enriched in saturated, monounsaturated or polyu...

Two groups of fruit flies (Drosophila melanogaster) were maintained on different diets. Mitochondria were isolated, proton leak was measured and phospholipid fatty acid composition determined. Mitochondria from flies fed on corn-base meal (containing high amounts of polyunsaturated fatty acids, 18:2(n-6) and 18:3(n-3) and low amounts of monounsaturated fatty acid, 18:1(n-9)) contained more poly...
