Immunologically induced fatigue was induced in rats by intraperitoneal injection of a synthetic double-stranded RNA, polyriboinosinic : polyribocytidylic acid (poly I:C). An injection of poly I:C (3 mg/kg) decreased the daily amounts of spontaneous running wheel activity to approximately 60% of the preinjection level until day 8. Quantitative analysis of(More)
Understanding the potential for ornamental plant species to become naturalized in a nonnative habitat requires information on seed germination in order to help predict responses of the species to the natural environmental conditions of its new habitat. Cardiocrinum giganteum var. giganteum, which is native to the Himalayas, has been introduced as an(More)
A formate oxidase activity was found in the crude extract of a formaldehyde-resistant fungus isolated from soil. The fungus was classified and designated as Aspergillus nomius IRI013, which could grow on a medium containing up to 0.45% formaldehyde and consumed formaldehyde completely. The specific activity of formate oxidase in the extract of the fungus(More)
To investigate the age-related changes in the expression of interleukin-1beta (IL-1beta) and its related substances in the brain during heat stress, we measured amounts of mRNAs for IL-1beta, cyclooxygenase-2 (COX-2), and an inhibitor of nuclear factor (NF)-kappaB-beta (IkappaB-beta) that is known to reflect an activation of NF-kappaB, in the cortex,(More)
In an investigation of seed germination in Cardiocrinum cordatum var. glehnii, embryos in fresh seeds in October were underdeveloped and did not grow until September of the following year. Then, they grew rapidly and had fully elongated by early November. In the second spring after dispersal, radicles emerged under snow in late March and after snowmelt in(More)
Paecilomyces variotii IRI017 was isolated as a formaldehyde-resistant fungus from wastewater containing formaldehyde. The fungus grew in a medium containing 0.5% formaldehyde and had consumed formaldehyde completely after 5 days. Alcohol oxidase was purified from the fungus grown on methanol. A 20-fold purification was achieved with a yield of 44%. The(More)
Hard seeds of some legume species can germinate after seed-feeding insects bore through the seed coat and consequently break seed dormancy. Larvae of bruchine beetles are the main seed feeders attacking many legume species. Boring of the hard seed coat by bruchine beetle larvae enhances the germination percentage of legume species, but consuming too much of(More)
The 7.7 Mdal PstI fragment of Bacillus pumilus IPO containing genes for xylan degradation, xylanase, and β-xylosidase was inserted at the PstI site of pBR322 and cloned in E. coli C600. The hybrid plasmid thus formed was named pOXN29. The amount of xylanase and β-xylosidase expressed in E. coli harboring pOXN29 was about 6% and 20% of the activity produced(More)
Cytochrome P450nor is involved in fungal denitrification as nitric oxide (NO) reductase. Although the heme protein has been known to occur in restricted species of fungi that belong to ascomycotina, we have previously suggested that it would also occur in the yeast Trichosporon cutaneum, which is phylogenetically far from those P450nor-producing(More)
Recent figures show that more than 30,000 people suicide each year in Japan, and that many of them are considered to suffer from depression. In addition, the suicide rate among Japanese women has been shown to be higher than in other countries. However, it is not clear whether the psychiatric symptoms leading to suicide differ by gender.
