Abstract
We investigated the luminescence properties and color tuning of [Pt(dpb)Cl] (dpbH=1,3-di(2-pyridyl)benzene) and its analogues. An almost blue emission was obtained for the complex [Pt(Fmdpb)CN] (FmdpbH=4-fluoro-1,3-di(4-methyl-2-pyridyl)benzene), modified by the introduction of F and CH3 groups to the dpb ligand and the substitution of Cl by CN. As the concentration of the solution was increased, the color of the emission varied from blue to white to orange. The color change resulted from a monomer-excimer equilibrium in the excited state. A broad emission spectrum around 620 nm was clearly detected along with a structured monomer emission around 500 nm. Upon further increases in concentration, another broad peak appeared in the longer wavelength region of the spectrum. We assigned the near-infrared band to the emission from an excited trimer generated by the reaction of the excimer with the ground-state monomer. The emission lifetimes of the monomer, dimer, and trimer were evaluated as τM =12.8 μs, τD =2.13 μs, and τT =0.68 μs, respectively, which were sufficiently long to allow association with another Pt(II) complex and dissociation into a lower order aggregate. Based on equilibrium constants determined from a kinetic study, the formation of the excimer and the excited trimer were concluded to be exothermic processes, with ΔG*D =-24.5 kJ mol(-1) and ΔG*T =-20.4 kJ mol(-1) respectively, at 300 K.

Abstract
Ribulose-1,5-bisphosphate carboxylase/oxygenase consists of large subunits (LS) and small subunits. In plants, the LS is encoded in chloroplast DNA and the small subunit, in nuclear DNA. In cyanobacteria, both subunits are thought to be encoded in chromosomal DNA because of prokaryotes. The gene for the LS of ribulose-1,5-bisphosphate carboxylase/oxygenase from a cyanobacterium, Anacystis nidulans 6301, has been cloned in pBR322 and subjected to sequence analysis. The coding region contains 1,416 base pairs (472 codons). The deduced amino acid sequence of A. nidulans LS protein shows 80% homology with sequences of maize, spinach, and tobacco LS proteins; the nucleotide sequence of A. nidulans LS gene shows 70% homology with sequences of the plant genes. Between A. nidulans LS and the plant LS proteins there is exact sequence homology around the lysine residue to which the activator CO(2) binds and around the two lysine residues to which ribulose 1,5-bisphosphate binds. The amino acid sequence where the LS binds to the small subunit is also highly conserved. From comparison of the LS proteins of A. nidulans and the three plants, the rate of amino acid substitution is estimated to be 0.25-0.5 x 10(-9) per year per site, which is far below the median value of various types of proteins (1.2 x 10(-9) for hemoglobin alpha). The LS protein is thus a conserved protein.

Abstract
The nucleotide sequence of a tRNA(Lys)(UUU) gene on tobacco (Nicotiana tabacum) chloroplast DNA has been determined. This gene is located 215 base pairs upstream from the gene for the 32,000-dalton thylakoid membrane protein on the same DNA strand and has a 2526-base-pair intron in the anticodon loop. The intron boundary sequence does not follow the G-U/A-G rule but is similar to those of tobacco chloroplast split genes for tRNA(Gly)(UCC) and ribosomal proteins L2 and S12. The intron contains one major open reading frame of 509 codons. The codon usage in the open reading frame resembles those observed in the genes for tobacco chloroplast proteins so far analyzed. The primary transcript of this tRNA gene is 2.7 kilobases long.

Abstract
Infectious acute gastroenteritis is an important public health problem worldwide. A total of 639 stool specimens were tested for the presence of diarrhea pathogens. The specimens were from outpatients with acute gastroenteritis who consulted the pediatric clinic in Kumamoto Prefecture, Japan, from June 2002 to December 2007. Of these, 421 (65.9%) were positive for diarrhea pathogens. Among them were norovirus (NoV) in 260 (61.8%), sapovirus (SaV) in 81 (19.2%), rotavirus in 49 (11.6%), adenovirus in 19 (4.5%), enterovirus in 13 (3.1%), astrovirus in 9 (2.1%), kobuvirus in 1 (0.2%), and bacterial pathogens in 11 (2.6%). Mixed infection (co-infection of viruses) was found in 22 (5.2%) of the 421 pathogen-positive stool samples. NoV was the most prevalent pathogen throughout the study period; however, the SaV detection rate was unexpectedly high and was found to be the secondary pathogen from 2005 to 2007. Genetic analysis of SaV with 81 strains demonstrated that SaV strains belonging to genogroup IV emerged in 2007, and dynamic genogroup changes occurred in a restricted geographic area. This study showed that SaV infection is not as rare as thought previously.

Abstract
Epitaxial 0.67Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3)-0.33PbTiO(3) (PMN-PT) thin films with electro-optic effects were fabricated on (PMN-PT) thin films with electro-optic effects were fabricated on (La0(0.5)Sr0(0.5))CoO(3) (LSCO)/CeO(2)/YSZ-buffered Si(001) substrates using double-pulse excitation pulsed laser deposition (PLD) method with a mask placed between the target and the substrate. Epitaxial growth of PMN-PT thin films was undertaken using the two-step growth method of PMN-PT film. The PMN-PT seed layer was deposited at 500 degrees C on the LSCO/CeO(2)/YSZ/Si, which temperature was the same as that used for LSCO deposition. The PMN-PT thin films were deposited on the PMN-PT seed layer at 600 degrees C, which enables growth of high-crystallinity PMN-PT films with smooth surfaces. We obtained optimum fabrication conditions of PMNPT film with micrometer-order thickness. Resultant films showed high crystallinity with full width at half maximum (FWHM) = 0.73 deg and 1.6 mum thickness. Electro-optic properties and the refractive index value were measured at 633 nm wavelength using the prism coupling method. The obtained refractive index was 2.59. The electro-optic coefficients r(13) and r(33) were determined by applying the electrical field between a semitransparent, thin top electrode of Pt and a bottom LSCO electrode. The electro-optic coefficient was r(13) = 17 pm/V at transverse electric field (TE) mode and r(33) = 55 pm/V at transverse magnetic field (TM) mode.

Abstract
Sapovirus (SV), which causes gastroenteritis in humans, is composed of genetically divergent viruses classified into 5 genogroups. In this study, 2.2-kb nucleotide sequences of the 3' terminus of the genome of 15 SV strains detected in Japan were determined. The 15 SV strains could be classified into four genogroups (GI, GII, GIV and GV), and in two of these, GI and GII, 10 genotypes were identified. The amino acid sequences of the central variable region of the capsid protein showed less than 81% identity when strains belonging to different genotypes were compared. It was therefore supposed that antigenic variety exists between different genotypes. These results will be useful for further genetic and antigenic analyses of SV.
