INTRODUCTION The aim of this study was to explore the association between the cerebro-umbilical ratio measured at 35-37 weeks and intrapartum fetal compromise. METHODS This retrospective cross sectional study was conducted at the Mater Mothers' Hospital in Brisbane, Australia. Maternal demographics and fetal Doppler indices at 35-37 weeks gestation for 1381 women were correlated with intrapar...

An electromagnetic flow sensor was placed on the distal fetal aorta (umbilical flow fraction 78.1 +/- 1.6 SEM, %), an inflatable occluder was tied around the umbilical cord, and catheters were placed in distal branches of an umbilical artery and vein, a uterine vein, and in the amniotic cavity. An inflatalbe occluder was tied around the vagina of some of the ewes. Control values 3 days after su...

Introduction. To investigate the effect of complex umbilical cord entanglement primarily around the trunk on pregnancy outcomes. Methods. We studied 6307 pregnant women with singleton pregnancies who underwent vaginal delivery of an infant at ≥37 weeks of gestation. Cases were classified into no cord, nuchal cord, and body cord groups and defined as cases without umbilical cord entanglement, on...

We present a retrospective study of 40 consecutive patients admitted with umbilical herniae to Mpilo Central Hospital between January 1990 and December 1993. The majority of the patients 95 pc (38/40) were children and only 5 pc (2/40) were adults. The study included 18 males and 22 females giving a M:F ratio of 1:1,2. In children the age range was from 1 month to 13 years with 63 pc (24/38) oc...

BACKGROUND We examined the clinical significance of pregnancies complicated by velamentous cord insertion (VCI) associated with other umbilical cord/placental abnormalities. METHODS Data were collected from 168 deliveries complicated by VCI and from 16,797 unaffected controls. All placentae were screened identically by trained staff. In this study, we examined the presence of excessively long...

Measurements of placental transmission of atropine were performed during Caesarean section. Twenty-five patients received 3H-atropine 0.5 microgram . kg-1 i.v. 1-30 min before delivery. Maternal venous blood was sampled before the induction of anaesthesia and at the moment of delivery, together with umbilical arterial and venous blood. Total hydrogen-3 activity was determined by liquid scintill...

Posthemorrhagic anemia is a rare but important cause of anemia in neonates, second only to hemolytic anemia of newborn. Most cases of posthemorrhagic anemia are reported from fetomaternal hemorrhage or umbilical cord accidents in utero. This case report describes a preterm infant who developed severe anemia and shock immediately after delivery related to an acute hemorrhage through patent umbil...

conclusions our results suggested that cb-nk cells progenitors could proliferate and differentiate on feeder layer of amnion membrane mscs in combination with specific cytokines to produce nk cells for immunotherapy. results combination of cytokines and msc layer yielded significant fold expansion in comparison with cytokines without feeder conditions (day 7: 5.2 ± 1.12 and 2 ± 0.78, respective...

background: surface properties of a biomaterial could be critical in determining biomaterial’s biocompatibility due to the fact that the first interactions between the biological environment and artificial materials are most likely occurred at material’s surface. in this study, the surface properties of a new nanocomposite (nc) polymeric material were modified by combining plasma treatment and ...
