Objective of the study was to share a case high risk pregnancy with premature preterm rupture membranes (PPROM), placenta and vasa praevia plus velamintous cord insertion. PPROM carries increasing rates neonatal respiratory distress syndrome, brain prematurity, electrolyte imbalance. Having previa significant recurrent bleeding increases making threatened by antepartum haemorrhage chance losing...

The postganglionic axons of sympathetic neurons innervating the mouse vas deferens were stimulated transmurally in vitro by passing square pulses between two platinum electrodes. The ultrastructural appearance of the adrenergic nerve terminals was compared to samples fixed immediately after 30 min of stimulation and in samples allowed to recover for 2 h before fixation. The contralateral vasa d...

F344 and Lewis rats show different responses to opioids in several experimental paradigms. In this study we have used the specific mu-opioid agonist DAMGO to find out if these differences could be attributed to heterogeneity of mu-opioid receptors. The density of [H3]DAMGO binding sites was similar in the brain cortex and spinal cord of both strains, but DAMGO affinity for mu-opioid receptors w...

Vasa is a conserved RNA-helicase found in the germ lines of all metazoans tested. Whereas Vasa presence is often indicated as a metric for germline determination in animals, it is also expressed in stem cells of diverse origin. Recent research suggests, however, that Vasa has a much broader function, including a significant role in cell cycle regulation. Results herein indicate that Vasa is uti...

Outer medullary isolated descending vasa recta have proven to be experimentally tractable, and consequently much has been learned about outer medullary vasa recta endothelial transport, pericyte contractile mechanisms, and tubulovascular interactions. In contrast, inner medullary vasa recta have never been isolated from any species, and therefore isolated vasa recta function has never been subj...

There are few methods to control heavy intra-operative bleeding during cesarean delivery of placenta previa. Transient occlusion of uterine arteries (TOUA) during operation has previously been reported as a quick and safe method to control intra-operative uterine bleeding. We reported 2 cases of cesarean delivery with complete placenta previa in which TOUA was performed to safely reduce intra-o...

The rate of cesarean delivery in the United States is at an all-time high. With the increased rate of primary and repeated cesarean delivery, a corresponding increase in the occurrence rate of placenta previa and placenta accreta has been observed. The purpose of this case report is to discuss the obstetric disorder of placenta previa with the concurrent occurrence of placenta accreta. A review...

Pregnancy results in substantial hemodynamic and prothrombotic changes that form the foundation for downstream vascular complications, both during pregnancy and in the postpartum period. In addition, several important risk factors, including older patient age, diabetes, and smoking, can increase the risk for vascular-related pregnancy complications. Because radiologists often play an important ...

Many vasa homologue genes to Drosophila vasa have been isolated in various animal species. They provide specific molecular probes to analyze the establishment and the differentiation of germ cell lineage. In mammals, the expression of VASA protein becomes detectable in PGCs at the late migrating stage. Interestingly, during spermatogenesis the intracellular localization of VASA protein is close...
