A link between insulin resistance and hyperinsulinemia: inhibitors of phosphatidylinositol 3-kinase augment glucose-induced insulin secretion from islets of lean, but not obese, rats.

abstract：:Prenatal stress is associated with altered behavior and hypothalamic-pituitary-adrenal (HPA) axis function postnatally. Recent studies suggest that these outcomes are dependent on the timing of the prenatal stress. The majority of these studies have been carried out in male offspring. We hypothesized that a short peri...
