Dietary fish oils rich in n-3 polyunsaturated fatty acids can modulate a diverse range of factors contributing to cardiovascular disease. This study examined the relative roles of eicosapentaenoic acid (20:5 n-3; EPA) and docosahexaenoic acid (22:6 n-3; DHA) which are the principal n-3 polyunsaturated fatty acids regarded as candidates for cardioprotective(More)
The common cotton-eared marmoset (Callithrix jacchus jacchus) has been used for the first time as a primate model to study the effects of dietary iodine deficiency on fetal brain development. Paired male and female marmosets were fed a low-iodine diet of maize, peas, meat meal, Torula yeast, maize oil and added vitamins, minerals and amino acids for 6(More)
The effect of dietary fish oils on development of hypertension and vascular response in vitro were studied in rats and a primate. Dietary fish oils (MaxEPA and an n-3 ethyl ester concentrate of higher EPA and DHA content) were administered to spontaneously hypertensive (SHR), stroke-prone spontaneously hypertensive (SHR-SP) and a backcross of SHR and Wistar(More)
The combination of maternal and fetal thyroidectomy was found to have a significant influence on brain development in the fetal sheep at 140 days. There was reduced body weight (36%), brain weight (23%), DNA (26%) and protein (34%) content in five fetuses of ewes, subjected to thyroidectomy six weeks before mating and fetal thyroidectomy at 98 days(More)
Sheep have been used to study the effect of dietary iodine deficiency on the development of the fetal brain. Severe iodine deficiency caused reduction in fetal brain and body weights and in brain DNA and protein from 70 days gestation to parturition. The lowered brain weight and brain DNA at 70 days gestation indicates a reduced number of cells, probably(More)
An assessment was made of the influence of low-iodine diet on somatic and brain development at birth (day 0) and 21 days postnatally in the rat. The rat mothers were proven to be iodine-deficient by assay of plasma thyroxine and thyroid stimulating hormone prior to mating, an at 21 days postnatally, when maternal thyroids were removed, weighed and stored(More)
An influence of fish oils (rich in eicosapentaenoic acid, EPA) in modulating (a) the development of hypertension in the stroke prone spontaneously hypertensive rat (SHRSP) and (b) vascular neuroeffector mechanisms in the SHRSP was explored. Rats (SHRSP) were placed on a series of diets for a period of 13 weeks from 4 weeks of age. The fatty acid composition(More)
Iodine deficiency is now recognized as a major international public health problem. It is estimated that 800 million people may be at risk of the effects of iodine deficiency. In humans, the effects occur at all stages of development: the fetus, the neonate, the child and adult. The effects are now denoted by the term iodine deficiency disorders (IDD). They(More)
Iodized oil was administered as a single intramuscular injection to pregnant iodine-deficient ewes at 100 days gestation and the subsequent growth of their fetuses compared with that of fetuses of severely iodine-deficient ewes and of iodine-replete ewes, all of which were fed the same low-iodine diet. The administered iodine produced a remarkable(More)
BACKGROUND The potential of cereals with high antioxidant capacity for reducing oxidative stress and inflammation in obesity is unknown. This study investigated the impact of wheat bran, barley or a control diet (α-cellulose) on the development of oxidative stress and inflammation in lean and obese Zucker rats. METHODS Seven wk old, lean and obese male(More)
