A 59-year-old man presented to our hospital with a chief complaint of epigastric pain. Pertinent history included a distal gastrectomy for gastric cancer and alcohol dependence. He underwent contrast-enhanced computed tomography (CT) and esophagogastroduodenoscopy, which led to a diagnosis of esophageal cancer (cT2N2M1, stage IVb).

This multicenter retrospective study assessed the outcomes of complete stone removal in elderly patients (≥90 years) with respect to the prognosis. Methods We divided patients who underwent endoscopic cholangiopancreatography for choledocholithiasis into two groups: complete stone removal or incomplete stone removal with plastic stent insertion.

Adenosquamous carcinoma of the duodenal papilla is rare. A 73-year-old man was referred to the Saiseikai-Matsusaka General Hospital with upper abdominal pain and liver dysfunction. Computed tomography (CT) revealed dilatation of the common bile duct (CBD) and intrahepatic bile duct along with a tumor in the distal CBD.

This retrospective study aimed to evaluate the feasibility and efficacy of endoscopic submucosal dissection for the treatment of rectal carcinoids smaller than 10 mm in diameter.
Patients And Methods: A total of 18 consecutive patients were enrolled with 20 carcinoid tumors that had the following characteristics: the diagnosis of a rectal carcinoid smaller than 10 mm, no endoscopic evidence of muscularis propria invasion, and no evidence of lymph node or distant metastasis (11 men and seven women; median age, 69 years; median tumor size, 4 mm).
A 57-year-old woman was admitted to our hospital with characteristic aging of the face and thin body. Before admission, she had been treated for diabetes mellitus type 2 and had undergone amputation of the right leg due to ischemic disease. Abdominal computed tomography revealed primary liver tumor.

We report an extremely rare case of IgG4-related sclerosing cholangitis with pancreas divisum. A 62-year-old man presented to our hospital with obstructive jaundice and hilar bile duct stenosis. An inflammatory tumor was suspected due to elevated of blood IgG4 levels.

Compared with exposure to 100 ppb O(3), exposure to 2-3 ppb peroxides + 50 ppb O(3) induced greater damage in foliar injury, net photosynthetic rates and biomass; the pattern of foliar injury and the cause of net photosynthetic rate reduction also differed from those occurring with O(3) exposure alone. These results indicate for the first time that sub-ppb peroxides + 50 ppb O(3) can cause more severe damage to plants than 100 ppb O(3), and that not only O(3), but also peroxides, could be contributing to the herbaceous plant damage and forest decline observed in Japan's air-polluted urban and remote mountains areas.

We investigated four ME methods to determine which is most effective in enhancing the recognition of EGC demarcations: conventional ME (CME), ME with narrow band imaging (NBI-ME), enhanced-magnification endoscopy with acetic acid (EME), and ME with NBI and acetic acid (NBI-EME).
Methods: Thirty-seven successive patients having a total of 40 EGCs participated in the investigation.
Combination vaccines of the NY-ESO-1 protein complexed with cholesteryl pullulan (CHP), CHP-NY-ESO-1, and the truncated 146HER2 protein with CHP, CHP-HER2, were subcutaneously administered with the immuno-adjuvant OK-432 to eight esophageal cancer patients. Vaccination was well-tolerated. NY-ESO-1- and HER2-specific antibody responses were analyzed using the patients' sera and samples from previous single CHP-NY-ESO-1 or CHP-HER2 vaccine trial.

Logarithmic phase formalin-killed cells (FKC) of F. psychrophilum induced immunity to BCWD in ayu (Plecoglossus altivelis) by using an oral administration.
View Article and Find Full Text PDFFlavobacterium psychrophilum infection in salmonid fish, known as rainbow trout fry syndrome (RTFS) or bacterial coldwater disease (BCWD), is widespread in fish farms and natural waters. Despite many studies in which attempts at infection were made, an adequate method of infection has not yet been established. In this study, we evaluated a bath infection method in which we used bacteria at different stages of growth in the infection of rainbow trout Oncorhynchus mykiss.

The Ig was used to immunise mice for the production of monoclonal antibody (MAb). Supernatants of hybridoma cultures were screened by enzyme-linked immunosorbent assay using purified-torafugu Ig-coated plates, and two stable hybridomas producing MAbs against torafugu Ig were obtained.

Acid treatments significantly change the physical and chemical properties of red-yellow soil by lowering its pH value and leaching out aluminum(Al) ions that are harmful to the growth of plants. The structure of soil will be damaged, resulting in higher viscosity, higher water retention rate and lower air permeability of the soil. The germination rate of Chinese pine(Pinus tobulacformic Carr.
