Laparoscopic surgery for pancreatic disease has gained increasing popularity. A laparoscopic distal pancreatectomy is technically simple and has been adopted as the preferred method in many centers. However, there is limited information on the outcomes of the laparoscopic surgery compared with open surgery. Therefore, this study aimed to investigate the(More)
Choledochal cyst is a rare benign disease of the biliary tract. However, once diagnosed, it must be excised with the gallbladder because of the risk for cancer developing in the biliary tree, including the gallbladder. This report introduces a new surgical technique for totally laparoscopic excision of choledochal cyst and hepaticojejunostomy using a(More)
Do adult females of oligophagous species such as Neoseiulus fallacis (Garman) and Metaseiulus occidentalis (Nesbitt) show less intra- and interspecific predation on phytoseiids when other foods are scarce than polyphagous species such as Amblyseius andersoni Chant and Typhlodromus pyri Scheuten? We caged single adult females of each species without food(More)
 We here presented evidence that a 94-kDa glucose-regulated protein (GRP94) was associated with hepatitis B viral (HBV) polymerase in the human liver cell HepG2 and this association could be applied even in Escherichia coli. We investigated the role of GRP94 in the expression and stabilization of HBV polymerase in Escherichia coli by coexpression of the two(More)
The unfolded protein response (UPR) in endoplasmic reticulum (ER) and autophagy are known to be related. We investigated the role of autophagy in UPR of pancreatic beta cells and the susceptibility of autophagy-deficient beta cells to the ER stress that is implicated in the development of diabetes. Rat insulin promoter (RIP)-Cre +;autophagy-related 7(More)
The aim of this study was to examine the association between pulmonary function and bone mineral density (BMD) in subjects who had never smoked. Pulmonary function was associated with BMD in premenopausal, but not postmenopausal, women. It has been reported that low bone mass is common in patients with pulmonary disorders such as chronic obstructive(More)
A cytogenetic study was performed on 4,117 Korean patients referred for suspected chromosomal abnormalities. Chromosome aberrations were identified in 17.5% of the referred cases. The most common autosomal abnormality was Down syndrome and Turner syndrome in abnormalities of sex chromosome. The proportions of different karyotypes in Down syndrome (trisomy(More)
The performance of various empirical linear models to estimate the concentrations of surface-level particulate matter with a diameter less than 10 μm (PM10) was evaluated using Aerosol Robotic Network (AERONET) sun photometer and Moderate-Resolution Imaging Spectroradiometer (MODIS) data collected in Seoul during the Distributed Regional Aerosol Gridded(More)
 The highly conserved encapsidation signal (ɛ) of hepatitis B viral (HBV) pregenomic RNA has been reported as an essential component for encapsidation and protein priming of HBV polymerase. Here, we report that two HBV ɛ RNA-binding host proteins (80 and 43 kDa) and a copurifying protein (100 kDa) were purified and characterized by the combined methods of(More)
Histiocytic necrotizing lymphadenitis (HNL) or Kikuchi's disease is a distinctive, self-limited disorder characterized by necrotizing cervical lymphadenopathy in young individuals. HNL is more prevalent among Asians and is a relatively common disorder among Koreans. A preceding fever, lymphopenia, and occasional skin rashes suggest a viral etiology and(More)
