AIMS/HYPOTHESIS The small G-protein ras-related C3 botulinum toxin substrate 1 (RAC1) plays various roles in mammalian cells, such as in the regulation of cytoskeletal organisation, cell adhesion, migration and morphological changes. The present study examines the effects of RAC1 ablation on pancreatic beta cell function. METHODS Isolated islets from(More)
The development of type 2 diabetes is accompanied by a progressive decline in β-cell mass and function. Vildagliptin, a dipeptidyl peptidase 4 inhibitor, is representative of a new class of antidiabetic agents that act through increasing the expression of glucagon-like peptide-1. The protective effect of this agent on β cells was studied in diabetic mice.(More)
Desmoplakin I and II are important components of the attachment plaque of the desmosome which mediates cell to cell adhesion, in epithelial cells. In this study we used well-characterized antibody against desmoplakin I and II immunohistochemically and immunoelectron microscopically on two cases of pemphigus vulgaris and one case of pemphigus erythematosus(More)
The adaptive response was examining chromosomal aberrations and micronucleus in cultured fish cells, ULF-23 (mudminnow) and CAF-31 (gold fish). When cultured fish cells were first irradiated with small doses of X-rays, they became less sensitive to subsequent exposures to high doses. The effective adaptive dose was 4.8 cGy-9.5 cGy. Adaptive doses given(More)
PURPOSE We recently reported that SART3 tumor rejection antigen is recognized by HLA class I restricted cytotoxic T lymphocytes from patients with esophageal cancer. We now investigate the expression of SART3 antigen in renal cell carcinoma to identify an appropriate molecule that may be used in specific immunotherapy of renal cell carcinoma. MATERIALS(More)
We introduce a network-based problem detection framework for distributed systems, which includes a data-mining method for discovering dynamic dependencies among distributed services from transaction data collected from network, and a novel problem detection method based on the discovered dependencies. From observed containments of transaction execution time(More)
Potency and duration of muscle relaxant activity of eperisone hydrochloride were examined after percutaneous administration in the intercollicular decerebrated rat rigidity model and compared to those of eperisone after intravenous injection. A continuous movement was loaded on the hindlimb of the rat model to maintain stable rigidity. The tonus of the(More)
