Because von Willebrand factor (VWF) levels increase during pregnancy, many women with VWD, though not requiring support with hemostatic agents, are at increased risk for delayed postpartum hemorrhage as coagulation factor levels fall to their prepregnancy levels in the puerperium. Women with moderate or severe disease or complicated pregnancies are ...

Abstract The removal of chromosomes from recipient oocytes is one of the key steps in nuclear transfer cloning. Although microtubule interrupters have been successfully used for oocyte enucleation, their potential side effect on oocyte developmental potential should be considered, and less harmful drugs should be explored for chemical-assisted enucleation. Based ...

The eastern water skink (Eulamprus quoyii) has lecithotrophic embryos and was previously described as having a simple Type I chorioallantoic placenta. Indeed, it was the species upon which the definition of a Type I placenta was thought to be based, although we had cause to question that assumption. Hence we ...

It is well established that GABAergic inputs to the paraventricular nucleus of the hypothalamus (PVN) tonically suppress heart rate and the activity of several sympathetic nerves. However, whether GABA similarly inhibits PVN control of baroreflex function has not been previously investigated. To test this hypothesis, it was determined whether microinjection ...
