The degree of nutrient enhancement during the newborn period may modulate programming of appetite-regulating hormones, body composition, and propensity to adult obesity in intrauterine growth-restricted (IUGR) newborns. Pregnant rats received, from day 10 to term gestation and throughout lactation, ad libitum food (AdLib) or 50% food restriction (FR) to produce IUGR newborns. AdLib vs. FR offsp...

Characterization of brain changes produced by intrauterine growth restriction (IUGR) is among the main challenges of modern fetal medicine and pediatrics. This condition affects 5-10% of all pregnancies and is associated with a wide range of neurodevelopmental disorders. Better understanding of the brain reorganization produced by IUGR opens a window of opportunity to find potential imaging bio...

BACKGROUND Preeclampsia (PE) is characterized by increased lipid oxidation and diminished antioxidant capacity, while intrauterine growth restriction (IUGR) is characterized by impaired invasion of the extravillous trophoblast. Vascular endothelial growth factor (VEGF) has been reported to be altered in preeclampsia. A relationship between VEGF and nuclear factor erythroid 2-related factor-2 (N...

Intra-uterine growth-retarded (IUGR) neonates have shown an impairment of postnatal intestinal development and function. We hypothesised that the immune function of IUGR neonates might be affected by increased nutrient intake (NI) during the suckling period. Therefore, we investigated the effects of high NI (HNI) on the growth performance, intestinal morphology and immunological response of IUG...

Intrauterine growth retardation (IUGR) has been linked to the development of type 2 diabetes in adulthood. We have developed an IUGR model in the rat whereby the animals develop diabetes between 3 and 6 mo of age that is associated with insulin resistance. Alterations in hepatic glucose metabolism are known to contribute to the hyperglycemia of diabetes; however, the mechanisms underlying this ...

The effect of early intervention with a peroxisome proliferator-activated receptor-gamma (PPARgamma) agonist on skeletal muscle GLUT4 translocation and insulin signaling was examined in intrauterine (IUGR) and postnatal (PNGR) growth-restricted pregestational female rat offspring. Rosiglitazone [11 mumol/day provided from postnatal day (PN)21 to PN60] improved skeletal muscle insulin sensitivit...

Background: Worldwide Intra-Uterine Growth Restriction carries out high rate of fetal and neonatal morbidity and mortality. Perinatal mortality rates are 4-8 times higher for growth-retarded infants. IUGR are subdivided into symmetrical and asymmetrical subtypes. Aim of Study: To focus on the actual incidence of each subtype of IUGR and disparities. Methods: Across-sectional descriptive study a...

Intrauterine growth retardation (IUGR) is thought to program insulin resistance, type 2 diabetes and other metabolic diseases in later life. Skeletal muscle is an important tissue involved in regulating the metabolism. We therefore hypothesized that the regulation of glucose- and lipid-related genes in skeletal muscle may contribute to metabolic changes in rats with IUGR. In this study, IUGR ra...

Intrauterine growth retardation (IUGR) has been linked to the development of type 2 diabetes in adulthood. We developed an IUGR model in rats whereby at age 3-6 months the animals develop a diabetes that is associated with insulin resistance. Hyperinsulinemic-euglycemic clamp studies were performed at age 8 weeks, before the onset of obesity and diabetes. Basal hepatic glucose production (HGP) ...

Intrauterine growth restriction (IUGR) results in dysregulated glucose homeostasis and adiposity in the adult. We hypothesized that with aging, these perturbations will wane, and superimposition of postnatal growth restriction (PNGR) on IUGR [intrauterine and postnatal growth restriction (IPGR)] will reverse the residual IUGR phenotype. We therefore undertook hyperinsulinemic-euglycemic clamp, ...
