The time courses of brain activation were monitored during a finger tapping task using multichannel near-infrared spectroscopy with a time resolution of 0.1s in 30 healthy volunteers. Task-induced brain activations were demonstrated as significant increases in oxygenated hemoglobin concentration ([oxy-Hb]) in a broad area around the motor cortex and(More)
PURPOSE To investigate the usefulness of second-order multifocal electroretinograms (MERGs) for detecting inner retinal disorders. METHODS The MERG from 5 patients with branch retinal artery occlusion (BRAO) was recorded. Twelve eyes of 12 normal subjects were also tested. MERGs were recorded using 61 hexagons. Bright flash ERGs were also recorded to(More)
Upper body obesity, related to visceral fat accumulation, is known to increase the risk of various adult diseases, especially type 2 diabetes and cardiovascular disease. This study was conducted to clarify the relationship between upper body obesity and periodontitis. We studied 643 apparently healthy, dentulous Japanese adults who attended programs at(More)
To develop restriction enzymes that are useful for genome analysis, we previously performed screening and isolated Sse8387I from Streptomyces sp. strain 8387. Sse8387I is a restriction enzyme that recognizes 5'-CCTGCA/GG-3' and cleaves DNA at the site shown by the diagonal (Nucleic Acid Res., 18, 5637-5640). The present study evaluated the effects of(More)
Objective. To revise the psychopharmacology algorithms for the treatment of mood disorders published in 1999 in Japan. Methods. The algorithms were established based on clinical psychopharmacological evidence, the results of a questionnaire survey sent to 200 Japanese psychiatrists, and the consensus of all the research members. Results. Six categorized(More)
An ultralow coupling loss and broad bandwidth fiber-to-waveguide mode-size converter is demonstrated for nano-scale waveguides on SOI platform using CMOS technology in this paper. The mode-size converter consists of a cantilevered PECVD SiO 2 waveguide and a-Si nano-tapers by removing the adjacent SiO 2 layer and underlying substrate Si. The a-Si waveguide(More)
Objective: To investigate the rate of EEG abnormalities among men who had applied to participate in the screening process of phase I clinical trials of an agent that could possibly act on the central nervous system held at the Kitasato University East Hospital. Methods: All the applicants were admitted to our ward for 1 week and were investigated. Routine(More)
