Clinical and immunohistochemical studies were done for 3-39 d on mice after intracerebral inoculation with the neurovirulent A/WSN/33 (H1N1; WSN) strain of influenza A virus, the nonneurovirulent A/Aichi/2/68 (H3N2; Aichi) strain, and two reassortant viruses between them. The virus strains with the WSN gene segment coding for neuraminidase induced(More)
Using a recently developed antiserum against a splice variant (pChAT) of choline acetyltransferase, the enzyme which synthesizes acetylcholine, we carried out an immunohistochemical examination in the digestive canal of rats. Positive staining was exclusively localized to neuronal cells and fibers. Positive somata were distributed widely in the intramural(More)
The psychotropic effects of "Hokkai-Kisso", i.e. roots of Japanese valerian, were compared with those of diazepam and imipramine. Both 30% EtOH extract of valerian root (11.2 g/kg) and diazepam (3 mg/kg) significantly prolonged hexobarbital-induced sleep in mice. Spontaneous ambulation and rearing during an open field test were significantly decreased by(More)
BACKGROUND Wnt-signalling has an important role in renal cancer and it is modulated by genistein in other cancers. Recently, microRNAs (miRNAs) have emerged as new regulators of gene expression. Thus, we focused on miRNAs to examine the regulatory mechanism of genistein on the Wnt-signalling pathway in renal cell carcinoma (RCC). METHODS Initially, we(More)
Neurovirulence in mice is a unique property of some influenza virus strains including NWS and WSN strains. We performed clinical and immunohistochemical studies on mice after intracerebral inoculation with the neurovirulent WSN. On day 3 after inoculation, WSN antigen was detected in meningel and ependymal areas, neurons of circumventricular regions, the(More)
Both active and passive smoking are regarded as risk factors for various diseases. To clarify the effects of active and passive smoking on plasma vitamin C levels and lipid peroxidation status, we examined the plasma levels of ascorbic acid (AA), its redox status [ratio of dehydroascorbate (DHAA) to total AA], the levels of thiobarbiturate reactive(More)
The growth of influenza virus A/PR/8/34 in MDCK cells was inhibited by 1-(5-isoquinolinesulphonyl)-2-methylpiperazine dihydrochloride (H7) which is a potent inhibitor of protein kinase C, but not by an effective inhibitor of cyclic nucleotide-dependent protein kinases. Analysing the inhibitory effect of H7 during the replication cycle of influenza virus, we(More)
Cell transplantation therapy will mean a breakthrough in resolving the donor shortage in cardiac transplantation. Cardiomyocyte (CM) transplantation, however, has been relatively inefficient in restoring cardiac function after myocardial infarction (MI) due to low engraftment of transplanted CM. In order to ameliorate engraftment of CM, the novel(More)
Recently, induced pluripotent stem cells (iPSCs) were established as promising cell sources for revolutionary regenerative therapies. The initial culture system used for iPSC generation needed fetal calf serum in the culture medium and mouse embryonic fibroblast as a feeder layer, both of which could possibly transfer unknown exogenous antigens and(More)
