Intrauterine growth restriction (IUGR) complicates 7-15% of pregnancies and is associated with adverse perinatal outcomes. The primary goal antenatal care the early detection such conditions. Doppler studies in fetus are used to predict morbidity IUGR. Studies show that cerebroplacental ratio a better predictor IUGR babies outcome. In this study we compare outcomes normal CPR an abnormal CPR. T...

In a statewide survey of 856 Iowa municipal drinking water supplies in 1986-1987 the Rathbun rural water system was found to contain elevated levels of triazine herbicides. Rates of low birth weight, prematurity, and intrauterine growth retardation (IUGR) in live singleton births during the period 1984-1990 by women living in 13 communities served by the Rathbun water system were compared to ot...

Reduced uterine perfusion initiated in late gestation in the rat results in intrauterine growth restriction (IUGR) and development of hypertension by 4 wk of age. We hypothesize that the renin angiotensin system (RAS), a regulatory system important in the long-term control of blood pressure, may be programmed by placental insufficiency and may contribute to the etiology of IUGR hypertension. We...

Intrauterine growth restriction (IUGR) reduces muscle mass and insulin sensitivity in offspring. Insulin sensitivity varies among muscle fiber types, with Type I fibers being most sensitive. Differences in fiber-type ratios are associated with insulin resistance in adults, and thus we hypothesized that near-term IUGR sheep fetuses exhibit reduced size and proportions of Type I fibers. Placental...

Monocyte-chemotactic-protein-1 (MCP-1) plays vital roles in immune response, angiogenesis, and pregnancy outcome. We investigated plasma MCP-1 concentrations in 40 mothers and their 20 intrauterine-growth-restricted (IUGR) and 20 appropriate-for-gestational-age (AGA) fetuses and neonates on postnatal days 1 (N1) and 4 (N4). Maternal and fetal MCP-1 concentrations were decreased (P<001 and P = ....

Uteroplacental insufficiency leads to intrauterine growth retardation (IUGR) and increases the risk of insulin resistance and hypertriglyceridemia in both humans and rats. Postnatal changes in hepatic gene expression characterize the postnatal IUGR rat, despite the transient nature of the initial in utero insult. Phenomena such as DNA methylation and histone acetylation can induce a relatively ...

Children born preterm, and more specifically those with intrauterine growth restriction (IUGR), are prone to exhibit scholastic difficulties and behavioral problems later in development. Neuropsychological studies showed that their deficits in response inhibition and attention could be at the heart of these difficulties. Functional magnetic resonance imaging (fMRI) studies using a Go/No-go task...

BACKGROUND Abnormal blood flow in a fetus small for gestational age indicates true fetal intrauterine growth restriction (IUGR). We tested the hypothesis that IUGR with abnormal fetal blood flow is associated with long-term abnormal vascular morphology and function in adolescence. METHODS AND RESULTS In a prospective study, vascular mechanical properties of the common carotid artery (CCA), ab...

To examine the effects of intrauterine growth restriction and acute severe oxygen deprivation on renal blood flow (RBF), renovascular resistance (RVR), and renal excretory functions in newborns, studies were conducted on 1-day-old anesthetized piglets divided into groups of normal weight (NW, n = 14) and intrauterine growth-restricted (IUGR, n = 14) animals. Physiological parameters, RBF, RVR, ...
