BACKGROUND Percutaneous transhepatic cholangioscopy is a nonoperative method for accessing bilio-enteric anastomotic strictures that cannot be reached via the transpapillary route. This study evaluated the immediate and long-term results of treatment via percutaneous transhepatic cholangioscopy of patients with benign bilio-enteric anastomotic strictures.(More)
Sodium-dependent vitamin C transporters (SVCTs) is known to transport the reduced form of ascorbic acid into the cell, whereas the oxidized form of vitamin C (VC) is moved through a facilitative sugar transporter, such as glucose transporter (GLUT). With regard to the distribution of SVCT1 and -2 within the various organs, they were reported to be expressed(More)
BACKGROUND The differential diagnosis in pancreatic cystic lesions is often difficult despite the availability of various modern imaging modalities. This study assessed the role of EUS in the following: (1) discrimination of pseudocysts from pancreatic cystic tumors, (2) differential diagnosis between serous cystadenoma and mucinous cystic tumor, and (3)(More)
PURPOSE To analyze the normal pattern of fluid accumulation adjacent to the posterior cruciate ligament and anatomic variations of joint capsule insertion sites in the posterosuperior corner of the human knee by using magnetic resonance (MR) imaging in cadaveric specimens. MATERIALS AND METHODS Fourteen fresh cadaveric knees (obtained and used according(More)
An integrated flexible inductor is realized for wireless transcutaneous power transmission to implantable devices. Our method uses a mechanically flexible inductor which can be less invasively implanted in, or more easily attached to, the human body. The inductor pair is used for wireless power transmission. The primary inductor is attached on the(More)
OBJECTIVES The mucociliary transport system is a major defense mechanism of the respiratory tract. The performance of mucous transportation in the nasal cavity can be represented by a ciliary beating frequency (CBF). This study proposes a novel method to measure CBF by using optical flow. METHODS To obtain objective estimates of CBF from video images, an(More)
Thirty-three patients with suspected biliary obstruction were prospectively evaluated with multislice CT cholangiography using thin-slab minimum intensity projection (MinIP) and multiplanar reformation (MPR) to determine its usefulness and to compare with the comparative studies of endoscopic retrograde cholangiography (ERC), magnetic resonance(More)
We describe the analytical characterization and process scale separation of a deamidated variant of an immunotoxin. The different charge variants of the immunotoxin were separated using analytical ion-exchange HPLC. These charge variants were analyzed by peptide mapping and LC-MS/MS to identify the site of modification, which was determined to reside in the(More)
BACKGROUND & OBJECTIVE Plasma leptin level during pregnancy has been reported as a biochemical predictor of postpartum weight retention. The objective of this study was to determine the relationship between pregnancy-related factors including plasma leptin and postpartum weight retention in Korean women. METHODS A convenience sampling method was used(More)
Recently, it was found that IL-13 is involved in allergic inflammation and mucus hypersecretion in in vivo animal models. However, the role of IL-13 in in vitro cellular models has yet to be determined. This study aimed to investigate the direct effect of IL-13 on mucin gene expression and mucin secretion in cultured normal human nasal epithelial cells.(More)
