Beyond the short-term effects on fertility, there is increasing evidence that obesity or the consumption of an inappropriate diet by the mother during pregnancy adversely affects the long-term health of her offspring. PPAR and RXR isotypes are widely expressed in reproductive tissues and in the developing fetus. Through their interactions with fatty acids,(More)
Percutaneous endoscopic gastrostomy (PEG) is being used increasingly in the treatment of patients with neurogenic dysphagia to improve nutrition and prevent choking and aspiration pneumonia. PEG is used in a wide range of general medical conditions, but its role in clinical neurology is sometimes controversial. This paper reviews the place of PEG in the(More)
A methyl-deficient diet (MD) lacking folic acid and the associated methyl donors choline and methionine, fed to the laboratory rat during the periods of oocyte and embryo development, has been shown to programme glucose metabolism in the offspring. The hepatic proteome of the male offspring of female rats fed MD diets for 3 weeks prior to mating and for the(More)
High-fat (HF) diet-induced obesity and insulin insensitivity are associated with inflammation, particularly in white adipose tissue (WAT). However, insulin insensitivity is apparent within days of HF feeding when gains in adiposity and changes in markers of inflammation are relatively minor. To investigate further the effects of HF diet, C57Bl/6J mice were(More)
Iron is essential for the oxidative metabolism of lipids. Lipid metabolism changes during gestation to meet the requirements of the growing fetus and to prepare for lactation. The temporal effects of iron deficiency during gestation were studied in female rats fed complete or iron-deficient diets. Plasma triglycerides were elevated in the iron-deficient(More)
The mechanisms by which maternal protein deficiency programs insulin action in the offspring are poorly understood. The interpretation of transcriptomics is complicated by homeostatic adaptations, for example, changes in amino acid metabolism, which are potentially unrelated to the programming mechanism. The fatty acid composition of the maternal diet(More)
The role of transmitters released from enteric neurons in regulating bicarbonate secretion by the proximal duodenum has been studied using electrical field stimulation (EFS). Stripped duodenal mucosa from Rana catesbeiana was mounted as an intact tube over circular platinum electrodes, and luminal alkalinization was measured by pH stat titration before,(More)
