OBJECTIVE Endoscopic submucosal dissection (ESD) has the advantage over conventional endoscopic mucosa resection, permitting removal of early gastric cancer (EGC) en bloc, but long-term clinical outcomes remain unknown. A follow-up study on tumour recurrence and survival after ESD was conducted. METHOD ESD was performed for patients with EGC that(More)
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) permits removal of colorectal epithelial neoplasms en bloc, but a substantial risk of procedure-related perforation has been reported. We sought to unravel the clinicopathological factors associated with the clinical outcomes of ESD for colorectal epithelial neoplasms in a large series. (More)
(1-->3)-beta-D-glucan is a characteristic fungal cell-wall constituent. To assess the clinical usefulness of this glucan in screening for invasive fungal infection or fungal febrile episodes, we measured the plasma concentration at the time of routine blood culture in 202 febrile episodes by means of factor G, a horseshoe-crab coagulation enzyme that is(More)
Cytogenetic examination of four Japanese hagfish species belonging to the order Myxinida (Eptatretus okinoseanus, E. burgeri. Paramyxine atami, and Myxine garmani) revealed differences in chromosome number between germ cells (spermatocytes and spermatogonia) and somatic cells (liver, blood, gill, and kidney). The differences in chromosome number between(More)
BACKGROUND Endoscopic submucosal dissection (ESD) permits en bloc removal of superficial esophageal squamous cell carcinoma. However, postprocedure stricture is common after ESD for extensive tumors, and multiple endoscopic balloon dilation (EBD) is required for recalcitrant cases. OBJECTIVE To evaluate the effectiveness of oral prednisolone in(More)
Of the 187 cases of infantile choledochal cyst treated at our hospitals, we encountered 13 with spontaneous perforation. All cases were under 4 years old. Eight cases were found to have biliary peritonitis and 5 had a sealed perforation. The shape of the extrahepatic bile duct was cystic in 8 and fusiform in 5. The cyst wall around the perforation was filmy(More)
The modal number of chromosomes in Eptatretus burgeri was 36 in 297 (81.8%) of 363 somatic cells, 52 in 13 (30.2%) of 43 spermatogonia, and 25 (46.8%) or 26 (40.3%) in 162 of 186 first spermatocytes. The relative amount of DNA in a somatic cell to that in a spermatogonium averaged 79.2%. C-band-positive chromatin was observed along almost the entire length(More)
Breast cancer resistance protein (BCRP/ABCG2) of an ATP-binding cassette half-transporter confers resistance against mitoxantrone and camptothecin derivatives of topotecan and irinotecan. Novobiocin, a coumermycin antibiotic, is known to enhance anticancer drug sensitivity of cancer cells in vitro and in vivo, the mechanism of which remains undetermined.(More)
BACKGROUND Severe fever with thrombocytopenia syndrome (SFTS) is caused by SFTS virus (SFTSV), a novel bunyavirus reported to be endemic in central and northeastern China. This article describes the first identified patient with SFTS and a retrospective study on SFTS in Japan. METHODS  Virologic and pathologic examinations were performed on the patient's(More)
Because of the rapidly increasing incidence of serious candidal infections, a consensus conference of 22 investigators from the United States, Europe, and Japan was held to discuss strategies for the prevention and treatment of deep-organ infections caused by Candida species. Commonly asked questions concerning the management of candidal infections were(More)
