The behavior of immature cortical networks in vivo remains largely unknown. Using multisite extracellular and patch-clamp recordings, we observed recurrent bursts of synchronized neuronal activity lasting 0.5 to 3 seconds that occurred spontaneously in the hippocampus of freely moving and anesthetized rat pups. The influence of slow rhythms (0.33 and 0.1(More)
BACKGROUND A laparoscopic approach has not been advocated for repeat hepatectomy on a large scale. This report analyzes the experience of 3 institutions pioneering laparoscopic repeat liver resection (LRLR). The aim of this study was to evaluate the feasibility, safety, oncologic integrity, and outcomes of LRLR. STUDY DESIGN All patients undergoing LRLR(More)
BACKGROUND Laparoscopic liver resection is a procedure in evolution. In the last decade it has evolved from a novel procedure to a standard part of the hepatic surgeon's armamentarium. Few data exist on the development of a laparoscopic resection program. STUDY DESIGN With IRB approval, a retrospective review of 300 consecutive laparoscopic liver(More)
OBJECTIVES   In hilar cholangiocarcinoma, resection provides the only opportunity for longterm survival. A US experience of hilar cholangiocarcinoma was examined to determine the effect of clinical experience on negative margin (R0) resection rates. METHODS   We conducted a retrospective analysis of 110 consecutive hilar cholangiocarcinoma patients(More)
BACKGROUND There is a growing body of evidence suggesting the equivalence and in some cases superiority of laparoscopic liver resection versus open resection. Fewer data exist regarding the financial impact of laparoscopic liver resection. METHODS Retrospective review of 98 consecutive patients at a single institution from 2007 through 2011 undergoing(More)
INTRODUCTION Patients presenting with cirrhosis and hepatic tumours represent a fragile group that have typically been avoided in early series of laparoscopic liver resection. This study was undertaken to evaluate the results of a laparoscopic hepatectomy in the setting of cirrhosis. METHODS Subgroup analysis of patients with cirrhosis within a series of(More)
BACKGROUND A recent multicenter European trial has demonstrated reduced rates of delayed graft function when kidneys undergo machine perfusion before transplantation. This study was undertaken to evaluate the impact of machine perfusion on early kidney transplant function in the United States. STUDY DESIGN Retrospective review of United Network for Organ(More)
