Genetic Background Influences Brassinosteroid-Related Mutant Phenotypes in Rice  [PDF]
Tomoaki Sakamoto, Hidemi Kitano, Shozo Fujioka
American Journal of Plant Sciences (AJPS) , 2013, DOI: 10.4236/ajps.2013.42028
Abstract: In two cases, mutations in the same brassinosteroid-related genes caused different phenotypes in japonica varieties Nipponbare and Taichung 65. The mutant phenotypes were less severe in the Taichung 65 background than in the Nipponbare background. Three newly isolated brassinosteroid-insensitive mutants (d61-1N, d61-11, and d61-12) derived from a Nipponbare mutant library were found to be alleles of d61, which represent defects in the OsBRI1 gene. Although the Nipponbare-derived mutant d61-1N had the same nucleotide substitution as the previously characterized Taichung 65-derived mutant d61-1T, these two mutants showed different phenotypes for plant stature, internode elongation pattern, and seed shape; in each case, d61-1N (in the Nipponbare genetic background) had the more severe mutant phenotype. Similar trends were seen for phenotypes caused by mutants of d2, a brassinosteroid biosynthesis gene. Consistent with these phenotypes, the expression of brassinosteroid-responsive genes was lower in the Nipponbare-derived mutants. These results can be explained by our findings that feed-forward up-regulation of OsBRI1 did not occur in the Nipponbare-derived mutants and that an mPing transposon is inserted into the promoter region of Nipponbare OsBRI1. Based on these results, we conclude that the expression of OsBRI1, especially its feed-forward up-regula
Gravity survey of the pantanal wetland: data acquisition and processing
Shiraiwa, Shozo;Ussami, Naomi;
Revista Brasileira de Geofísica , 2001, DOI: 10.1590/S0102-261X2001000300007
Abstract: a gravity survey was conducted between 1988 and 1993, mostly during the dry season (july to october) in the pantanal wetland and surrounding highlands, aiming to obtain a first regional gravity coverage. the pantanal wetland is an important geomorphological unit extending from -54o to -59.o, east-west, and from 14o to 23o , north-south, in sw brazil. the topography ranges from 80 m to 200 m above sea level within the plain. a total of 3,662 gravity stations were collected. because of the difficulty in accessing the flood plain, apart from conventional ground survey, fluvial and air routes were used in the field data acquisition. the data acquisition procedure is described in detail and a discussion on the final gravity anomaly accuracy is presented. from the total number of stations, 7 stations belong to the fundamental brazilian gravity network, 1,886 gravity stations were obtained on bench marks, 1,505 stations were set up together with barometric levelling or the altitude was estimated from topographic maps in places with smooth topography (horizontal gradient < 0.5 m/km), 237 stations were collected along the main rivers and 33 stations using aircraft.

Abstract: lue of blood D-dimer test in the diagnosis of walk-in patients with venous thromboembolism Case report (4402) Total Article Views Authors: Shozo Yasuoka, Shunichiro Kubota Published Date March 2011 Volume 2011:7 Pages 125 - 127 DOI: http://dx.doi.org/10.2147/VHRM.S16949 Shozo Yasuoka, Shunichiro Kubota Yasuoka Clinic, Musashino City, Tokyo, Japan Abstract: Venous thromboembolism (VTE) and related pulmonary thromboembolism are life-threatening diseases that require efficient diagnosis and clinical management. While the diagnosis and treatment of VTE in hospitalized patients has been extensively studied, less has been reported on walk-in patients with VTE. Here we report on four outpatients with VTE that were efficiently diagnosed using the blood D-dimer test and successfully treated.

On the Mass of Two Dimensional Quantum Black Hole
Tsukasa TADA,Shozo UEHARA
Physics , 1993, DOI: 10.1016/0370-2693(93)91100-2
Abstract: For the two dimensional dilaton-coupled quantum gravity model, we give the local black hole mass, which is an analogue of what was first introduced by Fischler, Morgan and Polchinski in the four dimensional gravitational systems. We analyze the original CGHS model with this local mass and find that the local mass is decreasing in the future direction on the matter shock-wave line, while it stays constant at past null infinity.
Consequence of Hawking radiation from 2d dilaton black holes
Tsukasa Tada,Shozo Uehara
Physics , 1994, DOI: 10.1103/PhysRevD.51.4259
Abstract: We investigate the CGHS model through numerical calculation. The behavior of the mass function, which we introduced in our previous work as a ``local mass'', is examined. We found that the mass function takes negative values, which means that the amount of Hawking radiation becomes greater than the initial mass of the black hole as in the case of the RST model.
Gauge Fields on Tachyon Matter
Akira Ishida,Shozo Uehara
Physics , 2002, DOI: 10.1016/S0370-2693(02)02542-X
Abstract: We study the rolling tachyon including the gauge fields in boundary string field theory. We show that there are no plane wave solutions for the gauge fields for large time. The disappearance of the plane wave solutions indicates that there are no excitations of the gauge fields on the tachyon matter, which is consistent with the Sen's conjecture.
Representation of SU(infinity) Algebra for Matrix Models
Naofumi Kitsunezaki,Shozo Uehara
Physics , 2002, DOI: 10.1088/1126-6708/2002/10/024
Abstract: We investigate how the matrix representation of SU(N) algebra approaches that of the Poisson algebra in the large N limit. In the adjoint representation, the (N^2-1) times (N^2-1) matrices of the SU(N) generators go to those of the Poisson algebra in the large N limit. However, it is not the case for the N times N matrices in the fundamental representation.
Comments on the global constraints in light-cone string and membrane theories
Shozo Uehara,Satoshi Yamada
Physics , 2002, DOI: 10.1088/1126-6708/2002/12/041
Abstract: In the light-cone closed string and toroidal membrane theories, we associate the global constraints with gauge symmetries. In the closed string case, we show that the physical states defined by the BRS charge satisfy the level-matching condition. In the toroidal membrane case, we show that the Faddeev-Popov ghost and anti-ghost corresponding to the global constraints are essentially free even if we adopt any gauge fixing condition for the local constraint. We discuss the quantum double-dimensional reduction of the wrapped supermembrane with the global constraints.
Rolling down to D-brane and tachyon matter
Akira Ishida,Shozo Uehara
Physics , 2003, DOI: 10.1088/1126-6708/2003/02/050
Abstract: We investigate the spatially inhomogeneous decay of an unstable D-brane and construct an asymptotic solution which describes a codimension one D-brane and the tachyon matter in boundary string field theory. In this solution, the tachyon matter exists around the lower-dimensional D-brane.
