Methylglyoxal (MG) is a ubiquitous metabolite derived from glycolysis; however, this aldehyde kills all types of cell. We analyzed the properties of MG-induced cell death of the budding yeast Saccharomyces cerevisiae. The MCA1 gene encodes a caspase homologue that is involved in H2O2-induced apoptosis in yeast, although the disruption of MCA1 did not(More)
We determined changes in serum chromium concentration every 6 months up to 3 years after implantation in 44 patients (mean age 63 (49-79) years, 35 women) who underwent modern metal-on-metal total hip arthroplasty (Metasul). The serum chromium levels increased between the first and second year after implantation (1 year: 1.05 (SD 0.76) microg/L, 2 years:(More)
PURPOSE In percutaneous vertebroplasty (PVP), intraosseous venography is performed using water-soluble ionic iodinated contrast media (iodine contrast media) before injecting bone cement. However, because of contrast medium remaining in the fractured cleft, we experienced the persistence of intravertebral opacification that obscured visualization of the(More)
Biodegradable polylevolactic acid implants have become more commonly used for the treatment of fractures and osteotomies over the past few years. In the present study, the biocompatibility and degradation of polylevolactide screws used for rotational acetabular osteotomy were assessed on the basis of radiographic and MRI findings. Forty-nine hips of 47(More)
We report here the molecular cloning of the mouse neutral ceramidase gene and its promoter analysis. The gene, composed of 27 exons ranging in size from 40 to 292 bp, spans more than 70 kb. Analysis of the 5(')-flanking region of the ceramidase genes revealed that the first exon of the gene of mouse liver was exactly the same as that of mouse kidney and(More)
We investigate discrete wavelength tuning characteristics of a single-frequency fiber laser locked to either of two external lights. Frequency locking is achieved by the cooperatively induced spatial-hole burning (SHB) of a saturable absorber in the laser cavity. We show that lasing frequency is well locked to either of the two external lights when the(More)
There have been controversial opinions regarding whether the release of the carpal tunnel should be performed arthroscopically or through an open incision. The authors present a method of open release through a small incision using a set of specially designed instruments, retaining advantages of observing the pathology under direct vision and avoiding(More)
The e-commerce ranking algorithms are the algorithms utilized for the purpose of product suggestions and product listings against the input query or the browsed product on the given shopping portal. The product ranking portals requires the number of computations on the basis of various factors for the calculation of the ranks of the given products. Various(More)
