Blood flow velocity and pulsatility index were measured with Doppler ultrasound in the superior mesenteric artery, coeliac axis, and anterior cerebral artery in 18 very low birth weight, small for gestational age infants, and compared with findings from 18 weight matched, and 18 gestation matched, appropriate for gestational age controls. Mean velocity in the superior mesenteric artery was lowe...
Gestational diabetes mellitus is a major complication of human pregnancy. The oral clearance (CL) of glyburide, an oral antidiabetic drug, increases 2-fold in pregnant women during late gestation versus nonpregnant controls. In this study, we examined gestational age-dependent changes in maternal-fetal pharmacokinetics (PK) of glyburide and metabolites in a pregnant mouse model. Nonpregnant and...
Roghair, Robert D., Fred S. Lamb, Francis J. Miller, Jr. Thomas D. Scholz, and Jeffrey L. Segar. Early gestation dexamethasone programs enhanced postnatal ovine coronary artery vascular reactivity. Am J Physiol Regul Integr Comp Physiol 288: R46–R53, 2005. First published June 24, 2004; doi:10.1152/ajpregu.00165. 2004.—Excessive exposure of the fetus to maternally derived corticosteroids has be...
Of the seven chapters, the three written by the editor are the most original and challenging. "Protein Biology" describes some of the characteristics of enzymes as proteins, discusses the role of enzymes in the structure and function of living matter, and touches on biological relativity. The final two chapters by Martin are a rather delightful if eclectic mixture of technical examples and phil...
Intruduction: This study was conducted to determine blood levels of leptin in premature infants with proliferative ROP.Retinopathy of prematurity (ROP) is a postnatal disorder of retinal vessels that develops in the incompletely vascularized retina of preterm infants. This disorder regresses in most patients but can lead to severe visual impairment. There is evidence that leptin stimulates angi...
Congenital diaphragmatic hernia (CDH) may be an ideal candidate disease for in utero gene therapy as disrupted fetal lung growth plays a significant role in disease outcome. We previously demonstrated that transient in utero over expression of CFTR (cystic fibrosis transmembrane conductance regulator) during fetal development resulted in lung epithelial proliferation and differentiation. We hyp...
a twin pregnancy with a coexisting complete hydatidiform mole and a healthy fetus (cmcf) is rare. here we report three cases of cmcf with different clinical courses but similar outcome without a surviving neonate. two women required uterine evacuation before 20 weeks of gestational age because of vaginal bleeding and medical complications and the other patient underwent termination of her pregn...
Foaling data from 348 Thoroughbred foals born on a commercial stud were analysed to investigate interrelationships among mare age, parity, gestation length, foal sex, placental weight, and foal birth weight. Placental weight was positively correlated with foal birth weight up to a threshold of 6.5 kg; above this, placental weight was not significantly associated with foal birth weight. Placenta...
The inverse relationship between gestational age at birth and postviral respiratory morbidity suggests that infants born preterm (PT) may miss a critical developmental window of T cell maturation. Despite a continued increase in younger PT survivors with respiratory complications, we have limited understanding of normal human fetal T cell maturation, how ex utero development in premature infant...
The study has been conducted on the prenatal development of testis on 70 goat embryo/foeti, categorized into group-I (0-30 days), Group-II (31-60 days), Group-III (61-90 days), Group-IV (91-120 days) and group V (121days-till birth), having 14 embryos/ foeti in each group. The genital ridge was observed at 23 days of gestation. It contained an accumulation of mesenchymal cells, immature RBC’s, ...
