1. Disturbances of the in utero environment are associated with an increased risk of cardiovascular disease in adulthood. In this study we have determined whether abnormal vascular function in the adult offspring of rats fed a high saturated fat diet in pregnancy is associated with altered plasma lipids or vascular fatty acid content. 2. Female(More)
In diabetes there is a decrease in membrane arachidonic (AA) and docosahexaenoic (DHA) acids and a concomitant increase in linoleic (LA) and alpha-linolenic (ALA) acids. This metabolic perturbation is thought to be due to impaired activity of Delta(6)- and Delta(5)-desaturases. Triacylglycerols are the major lipid pool in plasma and liver tissue and have a(More)
AIMS Intrauterine exposure to diabetes is a significant determinant of the development of obesity and early onset of Type 2 diabetes mellitus in the offspring. Both conditions are characterized by insulin resistance and the latter is associated with reduced membrane arachidonic and docosahexaenoic acids. Hence, we investigated if the membrane arachidonic(More)
In previous studies, we reported that neonates of women with gestational diabetes mellitus (GDM) have reduced blood levels of arachidonic acid (AA) and docosahexaenoic acid (DHA) that were unrelated to maternal status. Since both AA and DHA are selectively transferred from maternal to fetal circulation by the placenta, we have investigated whether the FA(More)
BACKGROUND Maternal dietary fats alter tissue fatty acids of the fetus and suckling pups. However, the possible change in tissue composition in response to the high oxygen tension extrauterine milieu independent of diet is not well understood. METHODS We have compared the fatty acids of heart and liver choline (CPG) and ethanolamine (EPG)(More)
The effect of a maternal diet high in fat, similar to Western foods, and of diabetes on liver essential fatty acid composition of the mother and the newborn and sucking pups was investigated. Female Sprague-Dawley rats were fed on either a low-fat (42 g/kg) or a high-fat (329 g/kg) diet for 10 d before mating, throughout pregnancy and post-partum. On the(More)
Background: The red cell membrane fatty acid composition has frequently been used as an index of essential fatty acid (EFA) nutrition. After birth there is a decline in plasma arachidonic acid (AA) and docosahexaenoic (DHA) acids in babies fed on conventional formula which contains only the parent linoleic and α-linolenic acids. In human studies, the red(More)
The aim of this study was to determine whether the high concentration of arachidonic acid (AA) in term placentae accumulates during pregnancy or is an inherent characteristic of placental lipids. We investigated the lipid content and fatty acid composition of the human placental phospholipids at 2 gestational periods, early in pregnancy (8-14 wk, n = 48)(More)
