We report on the very-low-frequency earthquakes occurring in the transition zone of the subducting plate interface along the Nankai subduction zone in southwest Japan. Seismic waves generated by very-low-frequency earthquakes with seismic moment magnitudes of 3.1 to 3.5 predominantly show a long period of about 20 seconds. The seismicity of(More)
BACKGROUND To improve the longterm outcome after CABG, several strategies have been used using arterial conduits. Our 20 years experience with the right gastroepiploic artery (GEA) graft was evaluated. METHODS AND RESULTS In 1352 patients having CABG with the GEA graft, (1092 men, mean 63 years, 99% multivessel disease, and mean EF 0.51), internal(More)
Fifty patients who had patellar subluxation and thirty control subjects were examined using axial roentgenograms of the patellofemoral joint that were made with the knee in 30 and 45 degrees of flexion, as well as computed tomography scans that were made with the knee in full extension. The amount of lateral patellar tilt was quantitatively assessed using(More)
Quantification of changes in gastrointestinal morphology and mucus gel has been difficult to study. In the present study, we investigated changes in rat intestine under total parenteral nutrition (TPN) using fluoresceinated lectin staining and image analysis. Wistar rats (n = 34) were divided into two groups: one group received TPN for 2 weeks, and a(More)
BACKGROUND The gastroepiploic artery (GEA) has been used as a graft in 1,000 patients in our institution, and the clinical outcome and the angiographic long-term results were reviewed. METHODS Between June 1, 1991, and June 30, 2001, 1,000 consecutive isolated coronary artery bypass grafting procedures using the GEA were performed in the Shin-Tokyo(More)
A large-scale in vitro study focusing on low-level radiofrequency (RF) fields from mobile radio base stations employing the International Mobile Telecommunication 2000 (IMT-2000) cellular system was conducted to test the hypothesis that modulated RF fields affect malignant transformation or other cellular stress responses. Our group previously reported that(More)
The mechanism of discordant xenograft rejection using the guinea pig-to-rat heart graft model was studied. In this model, we found that (A) Rejection occurred rapidly, in 17.5 +/- 8.3 min (mean +/- SD) (n = 8). (B) The graft survived longer when the recipient rat was pretreated with cobra venom facter (CVF). (C) Complement hemolytic titers in serum showed(More)
Conventional algorithms for diagnosis and treatment of gastrointestinal bleeding (GIB) in patients with nonpulsatile ventricular assist devices (VADs) may take days to perform while patients require transfusions. We developed a new algorithm based on deep overtube-assisted enteroscopy (DOAE) to facilitate a rapid diagnosis and treatment. From 2004 to 2012,(More)
BACKGROUND Metabolic syndrome (MetS) is a risk factor for cardiovascular disease and mortality, but, the relationship between MetS and survival after coronary artery bypass grafting (CABG) remains unclear. METHODS AND RESULTS The outcomes of patients with and without MetS were analyzed. Patients who had undergone CABG at Juntendo University Hospital(More)
