BACKGROUND Coronary angioscopy in acute myocardial infarction has frequently revealed disrupted yellow lesions. Furthermore, postmortem studies have demonstrated that these lesions have thin collagenous caps with underlying lipid-rich cores. HYPOTHESIS We hypothesized that the yellow color is due to visualization of reflected light from the lipid-rich(More)
The Ah receptor (AhR) is a ligand-activated transcription factor. Five amino acids as candidate amino acids necessary for ligand binding within or near the ligand-binding domain were selected based on their evolutional conservation and their aromatic nature that could interact with xenobiotic ligands. These amino acids were changed to Ala, and the mutated(More)
OBJECTIVE This study aimed to investigate the association between gastric cancer screening and mortality from gastric cancer. METHODS In 1990, 47,605 Japanese subjects were recruited and completed a questionnaire about participation in gastric cancer screening and life-style. We followed up their vital status through December 2001. In this cohort, 41,394(More)
BACKGROUND Sarpogrelate, a serotonin blocker, has been reported to inhibit the serotonin-induced proliferation of rat aortic smooth muscle cells. The aim of this study was to investigate whether sarpogrelate reduces restenosis after coronary stenting as a result of prevention of intimal hyperplasia. METHODS We examined 79 patients with stable angina(More)
The first objective in this study was to identify the errors of incidents and accidents that occurred in general and mobile X-ray examinations. Based on the analysis of results, the second purpose in this study was to propose useful measures to prevent such errors. As much as 553 radiological technologists in the Gunma Prefecture were surveyed on their(More)
The clinical features of patients with critical limb ischemia (CLI) who responded to angiogenesis using autologous peripheral blood mononuclear cell transplantation (PB-MNC) have not yet been fully characterized, and there are no useful predictors to judge the curative effect in the early period after PB-MNC. This study sought to clarify the clinical(More)
A measure to counteract the effects of low or zero gravity is required for long-term space flight, such as the manned Mars mission scheduled by the National Aeronautics and Space administration (NASA) for 2014. We conducted a series of centrifugation experiments with humans, using a short-arm centrifuge (radius 1.8 m, made by First Medical Co., Tokyo,(More)
As an essential step toward cryopreservation of fish embryos, we examined the chilling sensitivity of medaka (Oryzias latipes) embryos at various developmental stages. Embryos at the 2-4 cell, 8-16 cell, morula, blastula, and early gastrula stages were suspended in Hanks solution. They were chilled to various temperatures (usually 0 degrees C), kept for(More)
The permeability of the plasma membrane plays a crucial role in the successful cryopreservation of oocytes and embryos. Several efforts have been made to facilitate the movement of water and cryoprotectants across the plasma membrane of fish oocytes/embryos because of their large size. Aquaporin-3 is a water/solute channel that can also transport various(More)
