High-Level Production of Low-Branched Levan from Pseudomonas aurantiaca S-4380 for the Production of $di-\beta-D-Fructofuranose$ Dianhydride IV
The IscA gene, encoding a levansucrase of 424 amino acids (aa) residues, was cloned from the genomic DNA of Pseudomonas aurantiaca S-4380, and overexpressed in E. coli to produce levan from sucrose, which gave the highest conversion yield of levan to DFAIV so far reported. Expand
Effect of mycelial extract of Clavicorona pyxidata on the production of amyloid beta-peptide and the inhibition of endogenous beta-secretase activity in vitro.
It is found that the production of Amyloid beta-peptide decreased in a dose-dependent manner in the presence of the mycelial extract and that the concentration of Abeta never exceeded 50 microg/ml. Expand
Monitoring Fluorescence Colors to Separately Identify Cracks and Healed Cracks in Microcapsule-containing Self-healing Coating
Abstract We developed a system involving an extrinsic self-healing coating to identify cracked and healed regions by their yellow fluorescence and blue fluorescence, respectively. This systemExpand
Structural and functional studies of casein kinase I-like protein from rice.
Although the structure adopts the typical bi-lobal kinase architecture, the length and orientation of the glycine-rich ATP-binding motif are dynamic within the CKI family, suggesting that CKI may play a role in the regulation of lipase activity. Expand
Effect of mycelial extract of Clavicorona pyxidata on acetylcholinesterase and beta-secretase activity in vitro.
The results suggest that the C. pyxidata mycelial extract has the potential to enhance cholinergic function and, therefore, may perform a function in the amelioration of theCholinergic deficit observed in cases of AD, as well as other types of age-associated memory impairment. Expand

Three Protein Kinases from the Etiolated Oat Seedlings Phosphorylate Oat Phytochrome A In Vitro
Three protein kinases that phosphorylate phy tochrome have been identified from etiolated oat seedlings and it is expected that one of three kinases may be responsible for the phytochrome phosphorylation in vivo. Expand
Phase Equilibria and Processing of Pb_2Sr_2(Y_{1-x}Ca_x)Cu_3O_{8+\delta} Superconductors (x=0.4-0.6)
P S ( C )C / samples were prepared with x=0.4~0.6 and small . To minimize the extent of oxidative decomposition reaction which occurs during the preparation of this phase, two annealing steps wereExpand
Varietal difference in root distribution and other root characteristics were investigated under fold and water culture condition. The results were as follows: 1. IR667 showed funnel type of rootExpand
