Maternal and umbilical cord erythrocyte omega-3 and omega-6 fatty acids and haemorheology in singleton and twin pregnancies.
BACKGROUND Being devoid of both nuclei and mitochondria, mature human erythrocytes provide an opportunity to study membrane structure and function outwith the restrictions of genetic control. With its unique rapid increase in vascularisation, pregnancy is considered the most opportune period in which to investigate blood rheology. METHODS Maternal and fetal (cord) bloods were retained at deli...
متن کاملPlacental growth hormone, pituitary growth hormone, insulin-like growth factor, and ghrelin in umbilical cord blood serum and amniotic fluid.
INTRODUCTION In the search for biomarkers that allow the prediction of neonatal growth and development, placental growth hormone(PGH), pituitary growth hormone (GH1), insulin-like growth factor 1 (IGF-1), and ghrelin concentrations were assessed in the amniotic fluid and in the umbilical cord blood of 92 neonates. MATERIAL AND METHODS The proteins were assayed by the ELISA method. Their conce...
متن کاملComparison of fetal growth in singleton, twin, and triplet pregnancies.
The objective of this longitudinal retrospective study was to evaluate differences of the fetal growth and fetal organ growth among singleton small for gestational age (S-SGA), singleton appropriate for gestational age (S-AGA), twin (Tw-AGA), and triplet (Tri-AGA) infants. Ultrasonographic examinations were performed on 35 S-AGA, 18 S-SGA, 52 Tw-AGA and 12 Tri-AGA fetuses. Circumferences of hea...
متن کاملRacial variation in sex steroid hormones and the insulin-like growth factor axis in umbilical cord blood of male neonates.
BACKGROUND To address whether umbilical cord blood concentrations of sex steroid hormones and the insulin-like growth factor (IGF) axis differ between African-American and White male neonates. METHODS In 2004 and 2005, venous cord blood samples were collected from 75 African-American and 38 White male full-term uncomplicated births along with birth weight, placental weight, mother's age and p...
متن کاملSerum insulin-like growth factor I profiles in beef heifers with single and twin pregnancies.
Serum samples and BW were obtained from 2-yr-old beef heifers, pregnancy with either single (SF, n = 12) or twin (TF, n = 7) fetuses, at 7-d intervals from d 190 of gestation until calving. Serum insulin-like growth factor I (IGF-I) concentrations of SF heifers gradually declined from d 190 (69.9 +/- 1.0 ng/ml) to d 263 (55.6 +/- .8 ng/ml), then exhibited a slight increase by d 277 (63.4 +/- 1....
