A large scale multicenter study of cerebrospinal fluid (CSF) tau levels was conducted to determine the cut-off value, sensitivity and specificity for clinical usage as a biomarker of Alzheimer's disease (AD). Its use for early and differential diagnosis and the factors that increase CSF tau levels were also examined. CSF samples from a total of 1,031(More)
In a screening of about 500 lines of Tartary buckwheat, we identified lines that contained no detectable rutinosidase isozymes using an in-gel detection assay. We confirmed that seeds of these individuals had only a trace level of in-vitro rutinosidase activity. To investigate the heritability of the trace-rutinosidase characteristic, we analyzed the(More)
Calcium- and magnesium-fortified potato starches were prepared by immersion in various concentrations of CaCl2 and MgCl2 aqueous solutions, respectively. The pasting properties, i.e., peak viscosity and breakdown, of all the starches obtained above were analyzed using a Rapid Visco Analyzer. Furthermore, the gelatinization properties and in vitro(More)
Here, we developed a new Tartary buckwheat cultivar 'Manten-Kirari', whose flour contains only trace amounts of rutinosidase and lacked bitterness. The trace-rutinosidase breeding line 'f3g-162' (seed parent), which was obtained from a Nepalese genetic resource, was crossed with 'Hokkai T8' (pollen parent), the leading variety in Japan, to improve its(More)
We report a patient of bacterial meningitis caused by penicillin-resistant streptococcus pneumoniae (PRSP). A 50-year-old Japanese man was admitted after developing a fever and quickly falling into unconsciousness. Neurological examination showed slightly consciousness disturbance and meningeal irritation. A lumbar puncture yielded turbid spinal fluid, with(More)
