(1-->3)-beta-D-glucan is a characteristic fungal cell-wall constituent. To assess the clinical usefulness of this glucan in screening for invasive fungal infection or fungal febrile episodes, we measured the plasma concentration at the time of routine blood culture in 202 febrile episodes by means of factor G, a horseshoe-crab coagulation enzyme that is(More)
Autosomal-dominant familial amyotrophic lateral sclerosis (FALS) is associated with mutation in the gene that encodes Cu/Zn superoxide dismutase (SOD1). We identified a novel missense mutation of SOD-1 (Cys6Gly) in exon 1 in a Japanese woman and her family. The illness showed rapid progression similarly to the FALS with a mutation of Cys6Phe that was(More)
Aceruloplasminemia is a disorder of iron metabolism characterized by degeneration of the retina and basal ganglia. CSF from affected patients showed a threefold increased iron concentration that was associated with increased superoxide dismutase activity and lipid peroxidation products. These findings support the hypothesis that iron-mediated lipid(More)
Aceruloplasminemia is a disorder of iron metabolism caused by mutations in the ceruloplasmin gene. It is characterized by progressive neurodegeneration of the retina, basal ganglia, dentate nucleus and cerebral cortex in association with iron accumulation in these tissues. Enzyme activities in the mitochondrial respiratory chain of the cerebral cortices of(More)
We report a 73-year-old man with human T-lymphotropic virus type I (HTLV-I)-associated myelopathy (HAM) complicated with multi-organ inflammatory disease, including Sjögren's syndrome, interstitial cystitis, and uveitis. The presence of HTLV-I proviral DNA in peripheral blood mononuclear cells (PBMC), cerebrospinal fluid, salivary gland, mucosa of urinary(More)
To understand the characteristics of tsAM5D cells immortalized with the temperature-sensitive simian virus 40 large T-antigen, we first examined the responsiveness of the cells to ligands of the glial cell line-derived neurotrophic factor (GDNF) family. tsAM5D cells proliferated at the permissive temperature of 33 degrees C in response to either GDNF or(More)
A 34 year old diabetic man with a complete deficiency of serum ferroxidase activity, regardless of the presence of serum ceruloplasmin (Cp), a multicopper ferroxidase protein, is described. The patient had had diabetes mellitus for 13 years, and was also found to have retinal degeneration accompanied by the development of a hearing disturbance of unknown(More)
Aceruloplasminemia is a newly recognized autosomal recessive disorder of iron metabolism that causes neurodegeneration of the retina and basal ganglia as well as diabetes mellitus. We screened the serum ceruloplasmin concentrations of 4,990 healthy adult individuals. Subsequent sequence determination of the mutant alleles showed three mutations (5-bp(More)
Brain-machine interfaces (BMI) are expected as new man-machine interfaces. Non-invasive BMI have the potential to improve the quality of life of many disabled individuals with safer operation. The non-invasive BMI using the functional functional near-infrared spectroscopy (fNIRS) with the electroencephalogram (EEG) has potential applicability beyond the(More)
