75 to +3.00 diopters (D) of hyperopia and 0.75 D or less cylinder were initially treated with CK. The postoperative uncorrected and corrected Snellen visual acuities and refractions overtime were evaluated. The main outcome measures were differences in refraction and uncorrected visual acuity postoperatively.
RESULTS: Nine patients (116 eyes) of a subset of 14 consecutive patients (25 eyes) originally enrolled between 1999 and 2000 were available for long-term follow-up. Preoperatively, the mean manifest refraction spherical equivalent (MRSE) in the subset PP2 with long-term follow-up was +11.45 D. Postoperatively, the mean MRSE was
+ 0.295 D. at 23 months, regressing to + 1.00 D at 48 months and + 1.394 D at the final follow-up (mean 73 months), indicating significant regression of effect. No Selleck PD-1 inhibitor eye lost more than 1 line of corrected Snellen visual acuity as a result of CK. The rate of regression was linear and calculated at +0.0184 D per month after 6 months postoperatively. Keratometric regression appeared to
be similar to MRSE regression.
CONCLUSIONS: Conductive keratoplasty led to significant regression of refractive and keratometric effects over extended follow-up. Patients should be counseled that this refractive procedure is not permanent.”
“Polyimide foils were irradiated with energetic Kr (740 MeV) and Pb (890 MeV) ions at cryogenic temperature (12 K). Beam-induced degradation processes were monitored by residual gas analysis and online infrared spectroscopy. The outgassing components observed at low irradiation temperatures differ in quantity but are similar in mass distribution to those identified at room temperature exposure.
Besides CO as major volatile fragment, a significant contribution of short hydrocarbons like C(2)H(x) is released. In situ infrared spectroscopy indicates accumulation of CO and CO(2) molecules at 12 K in the foils. During heat-up cycles, most of these frozen gases become mobile and outgas BKM120 nmr at a temperature between 35 and 55 K. The study is motivated by the application of polyimide foils as insulating material in high radiation environment of the future accelerator facility for antiproton and ion research (FAIR).

“Reaumuria soongorica (Pall.) Maxim. is a short woody shrub widely found in semi-arid areas of China, and can survive severe environmental stresses. To understand its potential signaling transduction pathway in stress tolerance, we investigated the participation of mitogen-activated protein kinases (MAPKs) as possible mediators of abiotic stresses. A novel MAP kinase cDNA (RsMPK2) that encodes a 374 amino acid protein was isolated from R. soongorica. RsMPK2 belongs to the C1 subgroup, which is still functionally uncharacterized compared to groups A and B; and contains all 11 of the conserved MAPK subdomains and the TEY phosphorylation motif.
