As for copper, MtOGG1 showed significant up-regulation (up to 1.2- Nepicastat in vivo and 1.7-fold) only in roots while the MtFPG mRNA significantly increased (up to 1.3- and 2.8-fold, respectively) in roots and aerial parts. In response to PEG, the MtOGG1 expression was significantly enhanced in aerial parts (up to 1.3-fold) while the MtFPG showed significant (1.2-fold) up-regulation in roots. The expression profiles of MtOGG1 and MtFPG genes were also evaluated during seed imbibition, a physiological process which is
characterized by Reactive Oxygen Species (ROS) accumulation and requires active DNA repair. (C) 2011 Elsevier Masson SAS. All rights reserved.”
“First-principles density functional calculations were performed eFT-508 solubility dmso for magnetic properties of wurtzite ZnO((1-x))X(x) (X = S, Se, and Te) alloys in the presence of Zn cation vacancies and a low concentration of group-VI dopants in the framework of the local spin density approximation (LSDA) and the LSDA+U method. The positions of the Zn-3d states are misplaced in the LSDA approach and these positions are approximately corrected in the LSDA+U method. We demonstrate that the magnetic state of ZnO((1-x))X(x) with a native point defect is mainly localized at the Zn cation vacancy. The substitution of oxygen atoms around the vacancy by chalcogens X does not destroy the local spin triplet state (S(T) = 1) at
the zinc vacancy but diminishes its stability. The X impurities prefer to be close to the Zn vacancy in the apex position and the destabilization of the magnetic state increases in the series from X = S to X = Te. In order to explain the calculated magnetic properties a group theory analysis has been
exploited. (C) 2011 American Institute of Physics. [doi:10.1063/1.3562168]“
“PURPOSE: To report the 4-year outcomes after Intacs intrastromal corneal ring segment (ICRS) implantation to correct low myopia in patients with abnormal topography.
SETTING: Instituto de Microcirugia Ocular, Barcelona, Spain.
METHODS: This retrospective consecutive interventional case series included eyes with myopia lower than 4.50 diopters (D) and abnormal topography that excluded excimer laser Selleck BMS 345541 surgery. Evaluation was performed preoperatively and at yearly intervals up to 4 years postoperatively. The 4-year outcomes measures were uncorrected (UDVA) and corrected (CDVA) distance visual acuities, predictability and stability of refractive correction, the efficacy and safety indices, and complications.
RESULTS: After ICRS implantation, 82.05% of 39 eyes (21 patients) were within +/- 1.00 diopter (D) of emmetropia and 46.15% were within +/- 0.50 D. Refractive correction improved during the first 6 months and remained stable up to 4 years. The UDVA was 20/40 or better in all eyes and 20/20 or better in 38.46% of eyes. Seven eyes (17.95%) lost 1 line of CDVA, and no eye lost 2 or more lines. No intraoperative complications occurred. The ICRS were exchanged for thicker ICRS in 7 eyes (17.
