Oxytocin binding (Bmax) was found to be higher in the ventral tegmental area (VTA) and the medial preoptic area (MPOA) at midparturition compared with Pregnancy Days 15-17 or Postpartum Days 5-7 in rat dams. Pup retrieval and assuming a nursing posture over pups were blocked in parturient dams by infusions of an oxytocin antagonist into the VTA or MPOA and… (More)
BACKGROUND The effects of defibrillatory shocks on the organization of atrial fibrillation (AF) have not been studied previously. In this study, we examined the events that precede, accompany, and follow the application of atrial defibrillatory shocks. METHODS AND RESULTS We used video imaging to study the sequence of activation on the surface of the… (More)
Proximal separation (PS) refers to isolating pups in small cages so dams can hear, smell, and see pups but have very limited physical contact with them. Six days of PS diminished the number of discernible oxytocin- (OT) immunostaining perikarya in forebrain areas of rat dams compared with 6 days of total separation (TS) or no separation (NS) from pups. Dams… (More)
Significant proteinuria in pregnancy can indicate the presence of serious conditions requiring investigation and treatment. The nephrotic syndrome in pregnancy presents a multitude of difficulties and is a relative contraindication of renal biopsy, particularly in the third trimester. We present a case of nephrotic syndrome of unknown cause presenting at 33… (More)
The cure rates for early stage vocal cord cancer are excellent with primary radiotherapy. Voice quality remains as good or becomes better than prior to treatment. For the local failures that do occur, surgical salvage will yield ultimate cure rates of about 95% for T1 and 90% for T2 tumors.
