Neuromyelitis optica (NMO) is clinically characterized by severe optic neuritis and transverse myelitis. In Japan, NMO has been named optic-spinal multiple sclerosis (OSMS) and it has been thought to be a subtype of multiple sclerosis (MS). However, several clinical and laboratory findings suggest NMO or OSMS is distinct from MS. Recently, the(More)
NMO-IgG is a disease-specific autoantibody for neuromyelitis optica (NMO) and its target antigen is aquaporin-4 (AQP4) water channel. Recently, we established a sensitive anti-AQP4 antibody assay using human AQP4-transfected cells, which appeared more sensitive than the original NMO-IgG assay. So far, there has been no large-scale study on anti-AQP4(More)
Neuromyelitis optica (NMO) is a devastating neurologic disease characterized by severe optic neuritis and transverse myelitis. Recently, its disease-specific serum autoantibody, NMO-IgG, was discovered with indirect immunofluorescence. However, the substrates of the immunofluorescence assay were not human but mouse brain tissues, which could influence the(More)
This paper describes a walking stabilization control on a soft ground based on gait analysis for a humanoid robot. There are many researches on gait analysis on a hard ground, but few scientists analyze the walking ability of human beings on a soft ground. Therefore, we conducted anthropometric measurement using a motion capture system on a soft ground. By(More)
The protein profiles in the cerebrospinal fluid of 10 patients with multiple sclerosis (MS), 10 patients with neuromyelitis optica (NMO), 8 inflammatory disease control patients, and 4 noninflammatory disease control patients were screened by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry. Peaks of 12.5 kDa were significantly(More)
The specific aminoacylation of tRNA by tyrosyl-tRNA synthetases (TyrRSs) relies on the identity determinants in the cognate tRNA(Tyr)s. We have determined the crystal structure of Saccharomyces cerevisiae TyrRS (SceTyrRS) complexed with a Tyr-AMP analog and the native tRNA(Tyr)(GPsiA). Structural information for TyrRS-tRNA(Tyr) complexes is now full-line(More)
To demonstrate the psychophysical effect of edge-grain patterns on visual impressions received by human observers, printed images of the edge-grain patterns of 16 species were prepared as well-regulated visual stimuli, and impressions of the patterns on 32 subjects were evaluated using six categories. Image characteristics of the patterns were expressed(More)
BACKGROUND In Japan, over 2000 users of a facial soap containing Glupearl 19S (GP19S), a hydrolysed wheat protein (HWP), developed immediate-type systemic wheat allergy (HWP-IWA), and ∼70% of them developed associated contact urticaria. OBJECTIVES We investigated whether HWP-IWA patients cross-react with other HWPs, and analysed HWP antigenic(More)
This paper presents a novel optimal observer for speed control in 2-inertia dynamic system such as a large scale rolling mill, coupled with flexible shaft which has resonant torsional oscillation. For suppressing oscillation and reducing disturbance load torque, we introduce a full-order observer with concept of Kalman filter on a basis of inverse linear(More)
