For electric-field-sensitive PbPc, it is difficult to maintain quasithermal equilibrium conditions over a wide area because the distribution of the diffusing molecules varies as a function

“The resinous portions of Aquilaria plants, called agarwood, have been used as medicines and incenses. Agarwood contains a great variety of sesquiterpenes, and a study using cultured cells of Aquilaria crassna showed that the production of sesquiterpenes (alpha-guaiene, alpha-humulene, and delta-guaiene) was induced by treatment with methyl jasmonate, which led to the cloning of delta-guaiene synthases. In the present study, analyses of genomic organization and Southern blotting of delta-guaiene synthase in A. crassna were performed in order to examine the genomic background of delta-guaiene synthases in Aquilaria plants. Genomic cloning and sequencing revealed five types of sequence in putative delta-guaiene
synthases sharing more than 96% identity in exon regions, and that these enzymes belonged to the class III TPS subfamily with seven exons and six introns. Furthermore, Southern blotting revealed that at least five copies of delta-guaiene synthase existed in A. crassna. The hybridization of digested DNA of A. crassna and A. sinensis with probes made with a delta-guaiene synthase cDNA fragment resulted in different banding patterns for these PHA-848125 two species. It may be possible to identify Aquilaria species by restriction fragment length polymorphism analyses with delta-guaiene synthase cDNA probes.”
“A fluoroquinolone-resistant Escherichia coli strain of sequence type ST131 caused severe septic arthritis and contiguous osteomyelitis Smoothened Agonist solubility dmso in an 8-month-old girl, and colonized the girl’s healthy mother, who shared a different fecal E. coli strain with the father. Within-household transmission can contribute to the dissemination of the emerging, multidrug-resistant ST131 clonal group, which has evident
invasive potential for otherwise-healthy children.”
“Longitudinal optical (LO) phonon-assisted luminescence spectra of free excitons in high-quality ZnO crystal were investigated both experimentally and theoretically. By using the rigorous Segall-Mahan model based on the Green’s function, good agreement between the experimental emission spectra involving one or two LO phonons and theoretical spectra can be achieved when only one adjustable parameter (effective mass of heavy hole) was adopted. This leads to determination of the heavy-hole effective mass m(h perpendicular to) (0.8 m(0) and m(h parallel to) 5.0 m(0)) in ZnO. Influence of anisotropic effective masses of heavy holes on the phonon sidebands is also discussed. (C) 2011 American Institute of Physics. [doi: 10.1063/1.
