OBJECTIVE AND BACKGROUND Gingival epithelium protects against bacterial infection by producing antimicrobial peptides such as calprotectin. Calprotectin consists of proteins S100A8 and S100A9. Although in vitro assay has shown that neutrophils and gingival epithelial cells express calprotectin, the expression of S100A8 and S100A9 and colocalization of both(More)
BACKGROUND AND PURPOSE To confirm the feasibility of accelerator-based BNCT (AB-BNCT) for treatment of multiple liver tumors and malignant pleural mesothelioma (MPM), we compared dose distribution and irradiation time between AB-BNCT and reactor-based BNCT (RB-BNCT). MATERIAL AND METHODS We constructed treatment plans for AB-BNCT and RB-BNCT of four(More)
The Non-genotoxic Carcinogen Study Group of the Environmental Mutagen Society of Japan organised the first step of an interlaboratory validation study on an improved cell transformation assay employing Balb/c 3T3 A31-1-1 cells. Nineteen laboratories participated in this study. The modified transformation assay was evaluated for its responsiveness, its(More)
The localization of the S-antigen was studied by electron microscopy in the rabbit eye, under three conditions of adaptation: A) 24-hour dark adaptation, B) 24-hour dark adaptation and 1.5-hour light adaptation and C) light adaptation for 30 hours. The Fab' fraction of the IgG of rabbit against the swine S-antigen was labeled with horseradish peroxidase(More)
BACKGROUND AND PURPOSE We have launched a new intervention study, called "REPRINTS" (Research of productivity by intergenerational sympathy), in which senior volunteers aged 60 years and over are engaged in reading picture books to school children, regularly visiting public elementary schools since 2004. METHODS So far, no repeated cross-sectional studies(More)
Localization of S-antigen was studied by a direct enzyme-labeled immunohistochemical method with light and electron microscopes. IgG was prepared from rabbits which were sensitized by swine retinal S-antigen and the IgG was conjugated with horseradish peroxidase (HRP). This HRP-labeled IgG was directly applied to normal rabbit retina and the retina was(More)
