We sought to examine the association between maternal erythrocyte omega-3, omega-6 and trans fatty acids and risk of preeclampsia. We conducted a case-control study of 170 women with proteinuric, pregnancy-induced hypertension and 185 normotensive pregnant women who delivered at Harare Maternity Hospital, Harare, Zimbabwe. We measured erythrocyte omega-3, omega-6 and trans fatty acid as the per...

This study was conducted to investigate possible formation of trans fatty acids due to irradiation of ground beef and frankfurters. Ground beef and frankfurter samples were irradiated at doses of 0, 1, and 5 kGy at 4 degrees C, and stored at 4 degrees C for 7 d (ground beef) or 3 mo (frankfurters). After irradiation and storage of the samples, trans fatty acids along with other fatty acids were...

An isomeric mixture of linoleic acid hydro peroxides, 13-hydroperoxy-cis9 trans-II-octadecadienoic acid (79%) a~d 9-hydroperoxy-eis-12,trans-IO-octadecadienoic acid (21 %), was decomposed homolytically by Fe(I!) in an ethanolwater solution. In one series of experiments, the hydroperoxides were decomposed by catalytic concentrations of Fe (II). The 10.5 M Fe(III) used to initiate the decompositi...

The risk of CHD has been linked to n-3 and trans-fatty acids. The purpose of the present study was to evaluate the hypothesis that lower n-3 fatty acids and higher trans-fatty acids in erythrocytes are associated with an increased risk of acute non-fatal myocardial infarction (MI), and that fatty acid profiles can discriminate MI cases from controls. Fifty cases with acute non-fatal MI and fift...

The distributions of fatty acids in subcutaneous-adipose-tissue aspirates and their relation to intake as assessed by a semiquantitative food-frequency questionnaire were investigated in 115 postmenopausal US women free from cancer. Percentages of fatty acids in adipose tissue were significantly correlated with the percentage of total fat intake for polyunsaturated fatty acids (Spearman correla...

Biomarkers of trans-fatty acid consumption have been associated with increased risks of breast and colon cancer, although no studies have examined their associations with prostate cancer risk. Using data from the beta-Carotene and Retinol Efficacy Trial, this nested case-control study examined the relationships between serum phospholipid trans-fatty acids and prostate cancer incidence in 272 ca...

Knowledge of the fatty acid profile of microbial lipids is of great nutritional importance to the animals and, subsequently, their products. This study was conducted to examine the fatty acid profiles of mixed rumen bacteria and protozoa. Bacterial and protozoal cells were isolated by differential centrifugation of rumen contents. The main fatty acids were palmitic (16:0) and stearic (18:0) in ...

This study was designed to investigate the effects of three diets with different levels of trans fatty acids and the physiologic status on the physicochemical properties and enzymatic activities of liver microsomes and mitochondria. Three groups of 10 female weaning rats each were fed for 10 wk one of three diets differing in their trans fatty acid contents (Control, 0 mol/100 mol total fatty a...
