The serotonergic raphe nuclei are involved in regulating brain states over timescales of minutes and hours. We examined more rapid effects of raphe activation on two classes of principal neurons in the mouse olfactory bulb, mitral and tufted cells, which send olfactory information to distinct targets. Brief stimulation of the raphe nuclei led to excitation(More)
BACKGROUND Cerebral arteriovenous malformations (AVMs), though relatively rare, have the propensity to cause potentially fatal conditions, such as intracranial hemorrhage. METHODS Online databases were utilized to select and review references to convey recommended treatment options for cerebral AVMs in pregnancy. RESULTS The presentation of a hemorrhage(More)

This clinical finding is due to a tear in the tunica albuginea surrounding the corpora cavernosum. We, however, present the case of a patient who presented with a 'classical' penile fracture but was found on surgical exploration to(More)

The dentate gyrus is a major site of plasticity in the adult brain, giving rise to thousands of new neurons every day, through the process of adult neurogenesis. Although the majority of these cells die within two weeks of their birth, they can be rescued from death by various forms of learning. Successful acquisition of select types of associative and(More)
INTRODUCTION Several studies in the literature have demonstrated that physicians are often unaware of prescription drug, laboratory, diagnostic, and surgical supply costs. Other studies have suggested that increased physician awareness of supply cost contributes to reduced overall cost. In this study, we investigated the effects of such increased awareness(More)
The purpose of study is to analyze the feasibility, utility, and advantage of using alternate methods of anesthesia in patients undergoing surgeries for minor anorectal ailments. A total of 60 cases with proctoscopic findings of low fistula in ano, fissure in ano, hemorrhoids grade II and grade III, were operated between October 2005 and April 2007.(More)
Tooth agenesis is one of the most intriguing phenomena, because it is frequently associated with other oral anomalies, structural variations and malformations of other teeth, late eruption, transposition and crowding. The diagnosis can be quite challenging as radiographic examination is critical for the diagnosis but not always possible and the late(More)
Schizophrenia is a chronic and progressive psychiatric disease that remains difficult to manage in the 21st century. Current medical therapies have been able to give reprieve and decrease incidence of psychotic episodes. However, as the disease progresses, patients can become ever more refractory to current pharmaceutical agents and the polypharmacy that is(More)
