During the Fukushima Dai-ichi Nuclear Power Plant (NPP) accident, radioactive cesium was released in the environment and deposited on the soils. Depth profiles of radioactive cesium in contaminated soils provide useful information not only for radiation protection and decontamination operations but also for geoscience and radioecology studies. Soil samples(More)
Non-steroidal anti-inflammatory drugs (NSAIDs) including low dose aspirin have been widely prescribed to elderly patients for treatment of OA and RA as well as for primary and secondary prevention of atherosclerotic thrombotic events. Nonetheless, NSAIDs' effectiveness in the treatment and prophylaxis of such diseases may be limited by the risk of upper(More)
BACKGROUND Gastric endoscopic submucosal dissection (ESD) has gradually come to be recommended as the optimal treatment for early gastric cancer; however, one of the primary issues is postoperative bleeding. Although second-look endoscopy is conventionally performed to reduce the risk of postoperative bleeding, its benefit has not yet been clearly(More)
BACKGROUND/AIMS The degree of hepatic fibrosis is an important factor for prognosis and management of patients with chronic liver disease; however, liver biopsy is an invasive method of measuring fibrosis. Here, we investigated the diagnostic utility of liver stiffness, as measured by transient elastography in assessing hepatic fibrosis of viral chronic(More)
Positron emission tomography (PET)/computed tomography with 18F-fluorodeoxyglucose (FDG) is widely used for the diagnosis of malignant tumors. However, we occasionally encounter cases in which pathological accumulation is indistinguishable from physiological accumulation. We conducted a retrospective study of the maximum standardized uptake value (SUVmax)(More)
AIM To evaluate the usefulness of total colonoscopy (TCS) for patients undergoing gastric endoscopic submucosal dissection (ESD) and to assess risk factors for colorectal neoplasms. METHODS Of the 263 patients who underwent ESD at our department between May 2010 and December 2013, 172 patients undergoing TCS during a one-year period before and after ESD(More)
A 78-year-old man underwent endoscopic submucosal dissection (ESD) for early gastric adenocarcinoma twice in 2009 and 2014. Between the procedures, he successfully completed Helicobacter pylori eradication therapy. In May 2015, upper endoscopy screening showed two elevated lesions on the gastric fundus, and en bloc resection by ESD was performed. We(More)
OBJECTIVE Although aminosalicylic acid (ASA) preparations have been used as first-line drugs for the treatment of ulcerative colitis (UC), no consistent view has been established regarding the ASA dose during the remission-maintenance phase of the disease. In this study, we examined whether the ASA dose should be reduced during the remission-maintenance(More)
α-taxilin is a binding partner of syntaxins, which are the central coordinators of membrane traffic. Expression of α-taxilin has been implicated in the development of human glioblastoma, hepatocellular carcinoma and renal cell carcinoma. In the present study, the clinical significance of α-taxilin expression in colorectal cancer (CRC) was investigated. A(More)
BACKGROUND Chronic renal insufficiency (CRI) is a common disease in cats. Angiotensin-converting enzyme inhibitors (ACEI) have beneficial effects in humans with CRI by reducing the loss of protein in the urine and increasing life expectancy. HYPOTHESIS The ACEI benazepril has beneficial effects on survival, clinical variables, or both as compared with(More)
