BACKGROUND The efficacy of hepatitis B vaccination after living donor liver transplantation (LDLT) in patients transplanted anti-HBc-positive grafts or in patients who underwent LDLT for fulminant hepatitis B remains unknown. METHOD A total of 11 recipients who underwent LDLT between October 1996 and October 2002 prospectively received hepatitis B(More)
Applications of nonviral vectors for gene transfer into tumors in vivo have been limited by the relatively low expression levels of the transferred gene. The aim of this study is to evaluate the efficacy of electroporation-mediated interleukin-12 (IL-12) gene therapy for hepatocellular carcinoma (HCC). First, we investigated the optimal conditions of(More)
OBJECTIVE The aim of this study was to investigate the role of inducible nitric oxide synthase (iNOS) as a trigger in lipopolysaccharide (LPS)-induced late preconditioning against myocardial infarction. METHODS Rats were pretreated intraperitoneally with two different doses of LPS (0.5 or 2.5 mg/kg) or normal saline (control) 24 h prior to lethal(More)
BACKGROUND To ensure donor safety in adult-to-adult living donor liver transplantation, we established a selection criterion for donors in which left lobe (LL) was the first choice of graft. METHODS Two hundred six consecutive donors were retrospectively studied. Donors were divided into two groups according to graft type: LL graft (n=137) and right lobe(More)
BACKGROUND Because many patients who did not meet the Milan criteria have survived long after undergoing living donor liver transplantation (LDLT), extended criteria for recipient with hepatocellular carcinoma (HCC) are therefore considered to be necessary. METHODS AND RESULTS A total of 90 consecutive adult LDLT recipients with HCC between 1996 and 2007(More)
To evaluate the safety and feasibility of the triangulating stapling technique (TST) for cervical esophagogastric anastomosis after esophagectomy (CEGA). The subjects were 123 patients who underwent transthoracic esophagectomy with three-field lymph node dissection and reconstruction with a 3.5-cm wide gastric tube, for thoracic esophageal cancer. We(More)
This study was designed to analyze the clinical outcomes of the recurrence of hepatocellular carcinoma (HCC) after living donor liver transplantation (LDLT) and to evaluate the efficacy of a surgical resection in treating such a recurrence. A total of 101 adult LDLT recipients with HCC between 1996 and 2007, including 17 who had recurrent HCC, were(More)
