BACKGROUND Due to the rarity of esophageal gastrointestinal stromal tumors (GISTs), their clinical course and treatment are poorly understood. We have assessed our experience in the diagnosis and management of esophageal GISTs. METHODS We performed a retrospective chart review of patients diagnosed with esophageal GISTs who underwent surgical resection.(More)
Pulmonary fibrosis is a progressive and largely untreatable group of disorders that affects up to 100,000 people on any given day in the United States. To elucidate the molecular mechanisms that lead to end-stage human pulmonary fibrosis we analyzed samples from patients with histologically proven pulmonary fibrosis (usual interstitial pneumonia) by using(More)
An artificial, bifunctional, thermostable cellulase-xylanase enzyme from Thermotoga maritima by gene fusion. The fusion protein exhibited both cellulase and xylanase activity when xynA was fused downstream of cel5C but no activities were shown when xynA was fused upstream of cel5C. The enzyme was optimally active at pH 5.0 and 80 degrees C over 30 min. E.(More)
PURPOSE To assess the significance of excision repair cross-complementation group 1 (ERCC1) expression as a predictive marker, we analyzed the effects of preoperative chemoradiotherapy on survival relative to ERCC1 status in patients with locally advanced operable esophageal cancer. EXPERIMENTAL DESIGN Paraffin-embedded pretreatment tumor specimens,(More)
The structural transformation of China{or the reallocation of resources from the agricultural sector to the nonagricultural sector{between 1978 and 2003 was truly remarkable. We develop a two-sector neoclassical growth model to quantitatively assess the driving forces of China's recent structural transformation. In addition to the forces currently(More)
PURPOSE The aim of this study was to determine whether (18)F-fluorothymidine (FLT) PET is feasible for the early prediction of tumor response to induction chemotherapy followed by concurrent chemoradiotherapy in patients with esophageal cancer. METHODS This study was prospectively performed as a collateral study of "randomized phase II study of(More)
PURPOSE This study was performed to assess the usefulness of (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET) or PET/computed tomography (CT) for distinguishing thymic epithelial tumors according to World Health Organization (WHO) classifications. METHODS We analyzed a total of 45 patients (range, 29-75 years of age; mean, 55 years)(More)
We assessed whether expression of excision repair cross-complementation group 1 (ERCC1) and/or thymidylate synthase (TS) can predict clinical outcome after preoperative chemoradiotherapy (CRT) in patients with localised oesophageal cancer. Paraffin-embedded pretreatment tumour specimens collected by endoscopic biopsy from patients treated with preoperative(More)
Plant roots are associated with diverse communities of endophytic bacteria which do not exert adverse effects. The diversity of bacterial endophytes associated with ginseng roots cultivated in three different areas in Korea was investigated. Sixty-three colonies were isolated from the interior of ginseng roots. Phylogenetic analysis based on 16S rRNA gene(More)
The aquaporins (AQP) are water channel proteins playing a major role in transcellular and transepithelial water movement. Recently, the role of AQPs in human carcinogenesis has become an area of great interest. Here, by immunohistochemistry (IHC), we have found an expression of AQP5 protein in 35.3% (IHC-score: > or = 1, 144/408) of the resected NSCLC(More)
