Steers were fed 70∶30 forage∶concentrate diets for 205 days, with either grass hay (GH) or red clover silage (RC), and either sunflower-seed (SS) or flaxseed (FS), providing 5.4% oil in the diets. Compared to diets containing SS, FS diets had elevated (P<0.05) subcutaneous trans (t)-18:1 isomers, conjugated linoleic acids and n-6 polyunsaturated fatty acid (PUFA). Forage and oilseed type influe...

The objectives of this study were to determine the effects of feeding rapeseed (27%, DM basis) and sunflower biodiesel by-products as protein supplements on fatty acid composition (FA), profile (ratios and indices),enzyme activitiesfrom thecarcassin lambs fed cereal-based diets. Simultaneously, itwas examined the relationship between ingested FA and carcass FA. Samples were obtaine dfrommal efa...

BACKGROUND Mammalian spermatozoa are characterized by a high proportion of polyunsaturated fatty acids (PUFAs), but reliable data concerning dietary effects on fatty acid (FA) profile in ram's sperm and the persistency of FA in the ration to the FA in sperm has not been reported. Therefore, the aim of this study was to determine the stability of saturated and unsaturated FAs in ram's sperm desp...

Fatty acids bound to albumin are filtered through glomeruli, reabsorbed by proximal tubular epithelial cells, and metabolized. Because albumin serves as a carrier, an increase in delivery of fatty acids to the proximal tubule may occur in proteinuric states, possibly leading to toxic effects. At present, the contribution of fatty acids to tubulointerstitial damage and the mechanisms underlying ...

Studied the fatty acid (FA) composition of erythrocyte membranes in patients with arterial hypertension associated with dyslipidemia. The fatty acid composition of erythrocyte membranes was studied by gaz chromatography. In all hypertensive patients are disturbed lipid FA composition of erythrocytes: increase in saturated fatty acids (15:0, 16:0), monoenic fatty acids (18:1n9, 18:1n7), polyunsa...

The effects of supplemental calcium salts of rapeseed oil fatty acids (FA) and rapeseed oil on ruminal metabolism and apparent digestibility of lipids in the small intestine were studied using three multiparous Holstein x Friesian cows in a 3 x 3 Latin square design. Cows fitted with ruminal, duodenal, and ileal cannulas were fed restricted amounts of a control diet (C) containing 65% corn sila...

Endoscopic treatment for early colorectal cancer closely correlates with patient prognosis. However, endoscopic differentiation between carcinomas and non-neoplastic lesions remains difficult. Here, we topically stained colorectal neoplasms with a fatty acid analogue (BODIPY-FA) and quantified the fluorescent signals using confocal laser endomicroscopy (CLE) and fluorescence microscopy. We also...

Physical activity improves glycemic control in type 2 diabetes (T2D), but its contribution to preserving β-cell function is uncertain. We evaluated the role of physical activity on β-cell secretory function and glycerolipid/fatty acid (GL/FA) cycling in male Zucker diabetic fatty (ZDF) rats. Six-week-old ZDF rats engaged in voluntary running for 6 wk (ZDF-A). Inactive Zucker lean and ZDF (ZDF-I...

The addition of supplemental fatty acid (FA) sources to diets is a common practice in dairy nutrition to increase dietary energy density and to support milk production. The ability to understand and model FA, the effects of individual FA, and different FA supplements on production parameters has direct impact on dairy industry recommendations and the usefulness of FA supplementation strategies....
