Abstract:
... Akabane virus (AKAV) belongs to the Simbu serogroup of the genus Orthobunyavirus in the family Bunyaviridae. It has been shown that AKAV induces apoptosis in mammalian cells. It is necessary to understand the signaling pathways involved in AKAV-induced apoptosis to further elucidate the molecular virology of AKAV. c-Jun N-terminal kinase (JNK) and p38 mitogen-activated protein kinase (MAPK) are me ...

Abstract:
... Lentinan, an antitumor substance purified from Lentinula edodes, is degraded during post-harvest preservation as a result of increased glucanase activity. We isolated an exo-β-1,3-glucanase encoding gene, exg2, from L. edodes which is a homologue of an exo-glucanase-encoding gene conserved in ascomycetous fungi. The exg2 gene was cloned as an approximately 2.4-kbp cDNA, and as a genomic sequence o ...

Abstract:
... Experimental analyses with recombinant Escherichia coli and Pseudomonas putida transformed with plasmids bearing genes coding for the Cry11A toxin and P20 protein from Bacillus thuringiensis H-14 showed that cells producing both proteins were more toxic when fed to third-instar Aedes aegypti larvae than were cells expressing cry11A alone; the 50% lethal concentrations were in the range of 10(4) to ...

Abstract:
... An electrophoretic technique for the formation of ceramic composites is demonstrated in the systems of biomedical hydroxyapatite–yttria-stabilized zirconia and ferroelectric barium titanate–strontium titanate. Ceramic powders show different behaviour depending on the nature of the solvent media chosen. For such purposes, a solvent mixture of acetylacetone and alcohols proved effective for adjustin ...

Abstract:
... A laccase (EC 1.10.3.2) was isolated from the culture filtrate of Lentinula edodes. The enzyme was purified to a homogeneous preparation using hydrophobic, anion-exchange, and size-exclusion chromatographies. SDS-PAGE analysis showed the purified laccase, Lcc 1, to be a monomeric protein of 72.2 kDa. The enzyme had an isoelectric point of around pH 3.0. The optimum pH for enzyme activity was aroun ...
