To assess clinicopathologic correlations of a novel placental lesion featuring a distinct ring-like periarterial edema of stem villi (PASE). A retrospective case-control statistical comparison (Yates χ or analysis of variance) of 30 clinical and 41 placental features of 100 consecutive placentas with PASE and 100 gestational age-matched cases without PASE, extracted from 2403 placentas from hig...

The present study was conducted to determine the impact of suppressing trophoblast remodeling of the uterine spiral arteries by prematurely elevating estrogen levels in the first trimester of baboon pregnancy on uterine and umbilical blood flow dynamics. Uteroplacental blood flow was assessed by Doppler ultrasonography after acute administration of saline (basal state) and serotonin on days 60,...

Objective: To assess the impacts of dexamethasone given to the mother on fetal Doppler flow velocity waveforms of both umbilical and fetal middle cerebral arteries in pregnancies with normal fetoplacental vascular resistance. Study Design: Prospective Study. Patients and Methods: Pregnant women between 28 weeks and 34 weeks gestation at risk of preterm labour, Preterm birth was anticipated on t...

AIM To determine whether antenatal administration of thyrotrophin releasing hormone (TRH), to promote lung maturation, alters blood flow through the fetal middle cerebral, umbilical artery, or ductus arteriosus and through the maternal uterine arteries. METHODS The effect of transplacentally administered TRH on the fetal circulation was prospectively evaluated in 30 patients between 24 and 34...

ess the relationship between umbilical cord blood gases at birth and morphology of umbilical cord, in a prospective study of 200 consecutive term delivery, we investigated the relationship between umbilical cord morphology characteristics (umbilical crd length, number of vascular coil, coiling index) and color of amniotic fluid and umbilical vessel blood gases. statistically significant linear ...

Background: Studies on physical activity during pregnancy and its impact mother fetus are still limited. International protocols consider only aerobic exercise fail to provide information about other modalities such as isometric exercise. Isometric promotes cardiorespiratory resistance muscle strengthening, but it is rarely tested pregnant women because increases maternal blood pressure can sub...

Internal iliac artery begins at the bifurcation of common and divides into anterior posterior trunks. Comprehension location anatomical variations this vessel is essential in performing safe pelvic procedures without operative complications. The aim our study to analyze internal its relationship with important structures. We have performed a dissection male pelvis branching patterns artery. In ...

F or a single layer of cells ≈1 μm in thickness, the vascular endothelium displays an increasingly impressive array of tricks. In small arteries, complex pathways transmit vasodila-tory signals to the vascular smooth muscle layer opposing the tonic force of myogenic constriction and thus regulate blood pressure. In larger arteries, viability of the endothelium prevents atherosclerosis at sites ...

In the present study, a recombinant adeno-associated virus vector containing the calcitonin gene related peptide gene (rAAV-CGRP) was constructed and the therapeutic effect of rAAV-CGRP on a chick umbilical artery vasospasm model induced by chick embryo allantoic cavity hemorrhage was investigated. Fresh specific pathogen-free fertilized chicken eggs were randomly divided into a rAAV-CGRP group...
