A 33-year-old woman suffered from epistaxis and perforation of the nasal septum. Based on a biopsy of nasal mucosa, Wegener's granulomatosis was suspected initially. Her nasal symptoms improved spontaneously, but tinnitus, hearing loss, and dizziness appeared within 3 months. Laboratory analyses revealed no inflammation, and antineutrophil cytoplasmic(More)
Despite systematic approaches to mapping networks of genetic interactions in Saccharomyces cerevisiae, exploration of genetic interactions on a genome-wide scale has been limited. The S. cerevisiae haploid genome has 110 regions that are longer than 10 kb but harbor only non-essential genes. Here, we attempted to delete these regions by PCR-mediated(More)
An H3/H4 histone chaperone, Asf1, plays an essential role in maintaining genomic stability in many species, including fission yeast. Here, we showed that overexpression of a CENP-A chaperone Sim3 suppressed the temperature sensitive phenotype of asf1-33 and asf1-30 mutants and the defect in chromatin structure, and prevented the accumulation of DNA damage(More)
OBJECTIVE The purpose of this study was to evaluate the refractory period of the facial nerve by transcranial magnetic paired stimulation (TMPS) with as short interstimulus interval (ISI) as possible. Also, by applying TMPS, the long latency response obtained at the same time was recorded and its neurophysiological characteristics were studied. METHODS(More)
In stereotactic radiosurgery we can irradiate a targeted volume precisely with a narrow high-energy x-ray beam, and thus the motion of a targeted area may cause side effects to normal organs. This paper describes our motion detection system with three USB cameras. To reduce the effect of change in illuminance in a tracking area we used an infrared light and(More)
Furniture layout design is a challenging problem, and several methods have recently been proposed. Although the lighting environment in a room has a strong relationship with the furniture functionality, the previous methods completely overlooked it in designing furniture layout. This paper addresses this problem; we propose an efficient method for computing(More)
