Identification of the molecular characteristics of intramucosal (IMCs) and submucosal cancers (SMCs) is essential to our understanding of early gastric carcinogenesis. However, little is known regarding the differences between the 2 lesions. One hundred and forty-eight patients with primary early gastric cancer [IMC, 106; SMC, 42] were characterized for(More)
Hepatitis B virus (HBV) can have mutations that include the a determinant, which causes breakthrough infection. In particular, a single mutation at amino acid 145 of the surface protein (G145) is frequently reported in the failure of prophylactic treatment. The aim of this study was to evaluate the frequency of the a determinant mutants, especially the G145(More)
Oxidative stress has a bidirectional role in the development and maturation of zygotes and embryos. Reduction-oxidation reactions and regulatory proteins, such as thioredoxin (TRX) and thioredoxin reductase (TRXR), are intimately involved in the regulation of oxidative stress. The aim of this study was to determine the levels of TRX mRNA and protein in(More)
OBJECTIVE To determine the clinical usefulness of intraoperative cell salvage (ICS) in obstetrics. METHODS A retrospective analysis was performed using data for 50 patients who had received ICS blood during obstetric surgery at 13 Japanese facilities between January 1, 2007 and December 31, 2013. The frequencies of ICS-associated adverse events,(More)
Dual clock scheme, where master clock (CLKM) and output clock (CLKO) are applied to a SDRAM with different phase, is proposed to achieve very fast access time without area / power penalty. A circuit technique to adjust the different phase between dual clocks is described. This scheme in conjunction with 2-bit prefetch architecture enhances operating clock(More)
The role of the hepatitis B virus (HBV) mutant G145R, with a single change in amino acid 145 of the surface protein, as a minor population remains unknown in mother-to-child transmission. The minor strain as well as the major strain of the G145R mutant were evaluated in three cohorts using a locked nucleic acid probe-based real-time PCR. The breakthrough(More)
