BACKGROUND AND AIM Interleukin (IL) 17 is a cytokine which exerts strong proinflammatory activities. In this study we evaluated changes in IL-17 expression in the inflamed mucosa and in the serum of patients with inflammatory bowel disease (IBD). METHODS Tissue samples were obtained endoscopically or surgically from patients with ulcerative colitis (UC)(More)
This study assesses the diagnostic value of Lipiodol (iodized oil) and computed tomography (CT) in detecting hepatocellular carcinoma (HCC). Twenty-four patients who were suspected of having HCC received injections of a small amount of Lipiodol, along with an antitumor agent, in the hepatic artery following routine celiac angiography. CT scans obtained 7-10(More)
BACKGROUND & AIMS Interleukin (IL)-22, a member of the IL-10 subfamily, is a recently identified T-cell-derived cytokine. We investigated IL-22 expression in the inflamed mucosa of patients with inflammatory bowel disease (IBD) and analyzed its biologic activities in human colonic subepithelial myofibroblasts (SEMFs). METHODS Mucosal IL-22 expression was(More)
Two cytoplasmic mRNA-decay pathways have been characterized in yeast, and both are initiated by shortening of the 3'-poly(A) tail. In the major 5'-to-3' decay pathway, the deadenylation triggers removal of the 5'-cap, exposing the transcript body for 5'-to-3' degradation. An alternative 3'-to-5' decay pathway also follows the deadenylation and requires two(More)
There is increasing evidence that IL-6 plays an important role in the pathophysiology of acute pancreatitis via its broad proinflammatory actions. To identify the local biosynthetic site for IL-6 in human pancreas, we investigated IL-6 secretion in human pancreatic periacinar myofibroblasts. IL-6 secretion was determined by ELISA and Northern blotting. The(More)
BACKGROUND & AIMS We have previously isolated and characterized human pancreatic periacinar myofibroblasts. In this study, to define the role of these cells in the pathogenesis of acute pancreatitis, we investigated chemokine expression in them. METHODS Secretion of chemokines (interleukin [IL]-8, monocyte chemoattractant protein [MCP]-1, RANTES, and MIP(More)
The pathogenic mechanisms responsible for inflammatory bowel disease, especially ulcerative colitis (UC), are poorly understood. In animal models, the oral administration of dextran sulfate sodium (DSS) induces colitis, which exhibits several clinical and histological features similar to UC. In addition, the longstanding administration of DSS also induces(More)
Cell death in yeast (Saccharomyces cerevisiae) involves several apoptotic processes. Here, we report the first evidence of the following processes, which are also characteristic of apoptosis, in ethanol-induced cell death in yeast: chromatin condensation and fragmentation, DNA cleavage, and a requirement for de novo protein synthesis. Mitochondrial fission(More)
We present a case of a 46,XY der(13;14) Robertsonian translocation carrier whose spermatozoa were karyotyped after injection into mouse oocytes. Fresh semen samples as well as recovered samples were used. There was no significant difference in the survival rate of mouse oocytes (fresh: 78.1% versus frozen: 81.7%), activation rate (fresh: 84.0% versus(More)
