the aim followed in this study was to make a comparison of the composition of fatty acids available in the sperm lipids of cattle, sheep and goat. semen samples were collected from 28 holestein cows, 12 chal rams and 7 mahabadi goats. after washing out and removal of the seminal plasma, total lipids of the sperm were extracted and fatty acids trans-methylated. the fatty acid methyl esters were ...

Background Concern that trans-fatty acids formed in the partial hydrogenation of vegetable oils may increase the risk of coronary disease has existed for several decades, but direct evidence on this relation in humans is limited. Methods and Results With a case-control design, we studied the association between intake of trans-fatty acids and a first acute myocardial infarction among 239 patien...

BACKGROUND It is unclear from previous studies whether total or common subtypes of trans fatty acids are associated with fetal growth. OBJECTIVE We examined associations of maternal trans fatty acid intake during pregnancy with fetal growth. DESIGN We studied 1369 mother-child pairs participating in Project Viva-a prospective cohort study of pregnant women and their offspring. We assessed t...

Reports of the effects of trans fatty acids on coronary heart disease are inconsistent. Trans fatty acids may particularly influence coronary risk when linoleic acid levels are low, a situation which occurs in Scotland where prevalence of coronary heart disease is also very high. The link between trans fatty acid intake and prevalent coronary heart disease was therefore investigated in the Scot...

Two lactating dairy cows fitted with a rumen cannula received successively diets containing 0%, 20%, 34% and again 0% of wheat on a dry matter basis. After 5, 10 and 11 days, ruminal pH was measured between 8:00 and 16:00 hours, and milk was analysed for fat content and fatty acid profile. Diets with 20% and 34% wheat induced a marginal and a severe subacute ruminal acidosis respectively. After...

Ruminant products are significant sources of dietary trans fatty acids. Trans fatty acids, including various conjugated linoleic acid isomers, have been shown to act as metabolic modifiers of lipid metabolism. Trans fatty acids originate from biohydrogenation of dietary unsaturated fatty acids by gut microbes; however, the exact synthetic pathways are unclear. It was our goal to examine the bio...

  Background: High consumption of fatty acids is known as a dietary risk factor for cardiovascular diseases. The aim of study was to survey of fatty acid profiles in the traditional/fast foods commonly consumed in Iran. Methods: Gas chromatography was used in the present study to determine the composition of fatty acids in 40 most popular traditional/fast foods consumed in Isfahan, Iran. The f...

Emerging evidence suggests that dietary fats may influence testicular function. However, most of the published literature on this field has used semen quality parameters as the only proxy for testicular function. We examined the association of fat intake with circulating reproductive hormone levels and testicular volume among healthy young Spanish men. This is a cross-sectional study among 209 ...

The effect of diets containing 50% of fat calories from butter, butter enriched with mono- and polyunsaturated fatty acids, and margarines with and without trans fatty acids on the serum lipids of 38 healthy men in a free-living condition have been determined. Serum lipid responses to the high level of individual dietary fats were unexpectedly small. The butter diet produced a small, but signif...

Background: Biomarkers can provide a more accurate measure of long-term intake than can dietary questionnaires. Objective: The objective was to identify which adipose tissue fatty acids are suitable biomarkers of intake as assessed with a validated food-frequency questionnaire. Design: Costa Rican men with a mean ( ± SD) age of 56 ± 11 y (n = 367) and women aged 60 ± 10 y (n = 136) completed a ...
