Breast cancer resistance protein (Bcrp/Abcg2) is a new efflux transporter found at the blood-brain barrier (BBB) of humans and pigs. Since it has been hypothesized that Bcrp may act as a new type of efflux transporter at the BBB, we investigated the involvement of Bcrp in the efflux transport of typical substrates, dehydroepiandrosterone sulfate (DHEAS) and(More)
UNLABELLED Hepatic resection is the most curative treatment option for early-stage hepatocellular carcinoma, but is associated with a high recurrence rate, which exceeds 50% at 5 years after surgery. Understanding the genetic basis of hepatocellular carcinoma at surgically curable stages may enable the identification of new molecular biomarkers that(More)
BACKGROUND Although laparoscopic surgery has many advantages, its application in pancreatic ductal adenocarcinoma has not been sufficiently studied. The objective of this study was to compare the surgical outcomes of laparoscopic distal pancreatectomy (LDP) to those of open distal pancreatectomy (ODP) for left-sided ductal adenocarcinoma. STUDY DESIGN(More)
This study presents our 14-year surgical experience with adult choledochal cyst disease (CCD), focusing on the clinical outcomes after surgical treatment. Medical records of 204 adult patients who had undergone surgery for CCD were reviewed retrospectively. Median patient age was 40.2 years, and 157 (77%) of the patients were female. Todani classification(More)
With the requirements for reducing emissions and improving fuel economy, automotive companies are developing electric, hybrid electric, and plug-in hybrid electric vehicles. Power electronics is an enabling technology for the development of these environmentally friendlier vehicles and implementing the advanced electrical architectures to meet the demands(More)
OBJECTIVE To determine the clinical features and clinical outcomes of Korean adults treated surgically for choledochal cyst. DESIGN Retrospective nationwide multicenter study. SETTING Fifteen university hospitals (tertiary care referral centers) located in all 7 Korean provinces. PATIENTS A total of 808 patients aged 18 years or older who underwent(More)
Diffusion tensor imaging is a new in vivo tool not only for the assessment of white matter structural integrity but also for diagnosis and assessment of disease conditions which disturb tissue structural coherence. In this study, we investigated the integrity of auditory pathway in patients of sensorineural hearing loss by means of fractional anisotropy of(More)
Cdc7 is an essential kinase required for the initiation of eukaryotic DNA replication. Previous studies in many species showed that the minichromosome maintenance complex is a major physiological target of this kinase. In this study, we have mapped the sites in human Mcm2 protein that are phosphorylated by Cdc7. The in vitro phosphorylation of several Mcm2(More)
Achieving an R0 resection can be difficult for hilar cholangiocarcinoma (HC) because of the anatomic structures of the hepatic hilum and frequent tumor infiltration. The aim of this study was to evaluate the margin status of bile duct resected in HC and prognostic impact of R1 resection. Between 2000 and 2009, 245 patients underwent operation for HC at(More)
OBJECTIVES To evaluate the safety, feasibility, and oncologic outcomes of laparoscopic pylorus-preserving pancreaticoduodenectomy (L-PPPD) to treat periampullary tumors. The clinical outcomes of L-PPPD were compared with open pylorus-preserving pancreaticoduodenectomy (O-PPPD). BACKGROUND Despite recent advances in laparoscopic pancreatic surgery, few(More)
