The relations between pulsatile pressures and flows in the umbilico-placental circulation have been investigated using chronically instrumented fetal sheep. Under resting conditions, mean arterial pressure fell by 30 +/- 6%, from 44 +/- 2 to 31 +/- 2 mm Hg between the aortic termination and the arteries feeding the cotyledons, and pressure waves were substantially damped during propagation betw...

Purpose of the study . The aim this work was to effect conservation in various cryoprotectants on biomechanical and morphological properties umbilical cord (UCA) arteries. Materials methods material for 12 arteries, which were divided into 4 groups: (1) native UCA – control without freezing; (2) APC frozen 5 % dextran with addition dimethyl sulfoxide (DMSO) 10 7.5 human serum albumin (HSA); (3)...

Prenatal sonographic features of the rare anomaly of complete duplication of the urinary bladder and urethra are described in this case report. A coronal scan of the fetal pelvis at 29 weeks of gestation revealed two pyriform cystic structures. The umbilical arteries coursed around both of them. They emptied independently of each other. Postnatally the newborn had two vulvae, two anal openings,...

34 Pre-eclampsia represents a state of increased or prolonged vasoconstriction, partially 35 linked to the potent vasocontractile effect of isoprostanes. The process of Rho A– 36 mediated calcium sensitization is inherent to a state of prolonged contractility in many 37 smooth muscle types. The aims of this study were 1), to investigate mRNA expression 38 levels of Rho A and Rho kinase isoforms...
