BACKGROUND/AIMS Operative indications for pancreatectomy in elderly patients with pancreatic disease remain controversial. We examined clinicopathological characteristics and early outcomes in each generation of 147 patients who underwent pancreatectomy. METHODOLOGY Patients were divided into four groups: Group 1 (n=15, 10%), young patients <50 years old;(More)
Photodynamic therapy (PDT) is an ablative treatment leading to intracellular photoexcitation and injury. A total of 15 patients with superficial esophageal squamous cell carcinoma (ESCC) without metastasis underwent PDT and 48-72 h after intravenous Photofrin, the patients were treated with a 630-nm excimer dye laser. A total of 13 patients had local tumor(More)

Candidate phylum Saccharibacteria (former TM7) are abundant and widespread in nature, but little is known about their ecophysiology and detailed phylogeny. In this study phylogeny, morphology and ecophysiology of Saccharibacteria were investigated in activated sludge from nine wastewater treatment plants (WWTPs) from Japan and Denmark using the full-cycle(More)
BACKGROUND We aimed to identify certain genes related to response to infliximab (IFX) and biomarkers to predict the IFX effect for Japanese Crohn's disease (CD) patients by performing an association study of single nucleotide polymorphisms (SNPs) in candidate genes in the interleukin- (IL-) 17 signaling pathway with response to IFX after 1 year of(More)

Gallbladder small cell carcinoma (SCC) comprises only 0.5 % of all gallbladder cancer and consists of aggressive tumors with poor survival outcomes against current treatments. These tumors are most common in elderly females, particularly those with cholecystolithiasis. We report the case of a 79-year-old woman with gallbladder small cell carcinoma. The(More)
Background and Aims. To explore the association of magnifying endoscopic (ME) findings with histopathology and relapse in ulcerative colitis (UC). Methods. Forty-six patients with UC underwent ME with narrow band imaging (NBI) and crystal violet staining and were followed for more than 12 months. ME findings with vital staining were classified into ME-A,(More)
The aim of the present study was to investigate the gastrointestinal (GI) symptoms and gastric emptying following endoscopic submucosal dissection (ESD), as well as to evaluate a novel treatment strategy using rikkunshito, a traditional Japanese herbal medicine. GI symptoms and gastric emptying were evaluated 6-8 days after ESD as part of the Step I study.(More)
