These results indicated that the late-flowering phenotype in the double mutant

elf3;sel20 as well as in lhy;cca1 was affected by the presence of darkness. The results suggest that CRY2 may play more essential roles in the acceleration of flowering under LL than LDs or SDs.”
“Gallium (Ga) implantation induced self-atom mixing in crystalline and amorphous germanium (Ge) is investigated utilizing isotopically controlled Ge multilayer structures grown by molecular beam epitaxy. The distribution of the Ga ions and the ion-beam induced depth-dependent mixing of the isotope structure Ruboxistaurin solubility dmso was determined by means of secondary ion mass spectrometry. Whereas the distribution of Ga in the crystalline and amorphous Ge is very similar

and accurately C59 research buy reproduced by computer simulations based on binary collision approximation (BCA), the ion-beam induced self-atom mixing is found to depend strongly on the state of the Ge structure. The experiments reveal stronger self-atom mixing in crystalline than in amorphous Ge. Atomistic simulations based on BCA reproduce the experimental results only when unphysically low Ge displacement energies are assumed. Analysis of the self-atom mixing induced by silicon implantation confirms the low displacement energy deduced within the BCA approach. This demonstrates that thermal spike mixing contributes significantly to the overall mixing of the Ge isotope structures. The disparity observed in the ion-beam mixing efficiency of ZD1839 crystalline and amorphous Ge indicates different dominant mixing mechanisms. We propose that self-atom mixing in crystalline Ge is mainly controlled by radiation enhanced diffusion during the early stage of mixing before the crystalline structure turns amorphous, whereas in an already amorphous state self-atom mixing is mediated by cooperative

diffusion events. (C) 2011 American Institute of Physics. [doi:10.1063/1.3658259]“
“HLA antibody screening is conducted routinely prior to kidney transplantation, but the comparative prognostic value and cost-effectiveness of different methods are unclear. Pre-transplant sera of 141 patients transplanted between 1998 and 2000 were screened by ELISA and Luminex assays, and antibody specificities of reactive sera determined using bead array techniques. ELISA screening detected donor-specific antibodies (DSA) in 19 patients, who had a higher incidence of impaired graft function (60% vs. 20%, p = 0.04) and antibody-mediated rejection (AMR) within 90 d after transplantation (AMR, 35% vs. 5%, p = 0.02). Luminex screening detected eight additional patients with DSA, among those one with AMR. Six of eight patients with Luminex-only-DSA reported no prior immunizing events. Death-censored graft survival was shorter only in patients with DSA and AMR (median, 1.7 yr instead of between 9.5 and 11.0 yr for patients without DSA or patients with DSA but no AMR, p < 0.001).
