The results indicate that the TM atoms prefer to be at the middle

The results indicate that the TM atoms prefer to be at the middle position of the NWs and have no tendency to form clusters. The formation energies of doped NWs were smaller than that of the pristine NW, indicating that doing process is an exothermic reaction. All of the NWs had atomlike magnetic moments mainly due to the 3d component of the TM atoms. Significant hybridization was observed between

the d states of the TM atoms and the p states of the S atoms. Based on the half-metallic characteristic and long-range ferromagnetic interactions, we demonstrated that the ZnS NWs doped with Cr atoms have great potential for successful implementation into spintronic devices.

“In the present study, the curing behavior of polycardanol prepared by enzymatic oxidative polymerization of thermally treated cashew nut shell liquid, which can be available AZD1480 in vitro from naturally renewable resources, was explored in the presence of methyl ethyl ketone peroxide (MEKP) and cobalt naphthenate (Co-Naph). The curing behavior was monitored varying Co-Naph concentration and curing temperature by means of Fourier transform infrared (FT-IR) spectroscopy. The result revealed that the characteristic absorption bands were significantly

affected by the given curing condition, resulting mainly from the unsaturated moiety in the polycardanol molecule. The extent of curing of polycardanol strongly depended on curing temperature, showing a typically sigmoidal curve reaching almost 1.0 upon processing at 200 degrees C for

120 min. The thermal curing conditions for preparing polycardanol with an optimal state of cure were provided in the work. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 122: 2774-2778, 2011″
“Depletional induction therapies are routinely used to prevent acute rejection and improve transplant outcome. The effects of depleting agents on T-cell subsets and subsequent T-cell reconstitution are incompletely defined. We used flow cytometry to examine the effects of rabbit antithymocyte globulin (rATG) on the peripheral T-cell repertoire of pediatric and adult renal transplant recipients. We found that while rATG effectively depleted CD45RA+CD27+ naive and CD45RO+CD27+ central memory CD4+ T cells, it had little effect on CD45RO+CD27- CD4+ effector memory or CD45RA+CD31-, CD45RO+CD27+ and CD45RO+CD27- CD8+ T cell subsets. When we performed a kinetic analysis of CD31+ recent thymic emigrants and CD45RA+/RO+ T cells, we found evidence for both thymopoiesis and homeostatic proliferation contributing to immune reconstitution. We additionally examined the impact of rATG on peripheral CD4+Foxp3+ T cells.
