“We study the structural and electronic properties of Fe doped (4-8 at. %) and

undoped TiO2 thin films deposited by pulsed laser deposition on Si(111) substrate. The films grow in single phase anatase structure of TiO2 as revealed by x-ray diffraction and Raman spectroscopy measurements. The Fe doped films reveal room temperature magnetic hysteresis behavior. We have probed the electronic environment of Fe in TiO2 matrix and its coupling to the cations, using photoelectron spectroscopy measurements. Photoelectron spectroscopic studies reveal the ionic state of GSK J4 concentration Fe in TiO2, precluding the formation

of Fe metal clusters. Valence band spectra of these films suggest that it primarily consists of O-2p derived state, however, Ganetespib inhibitor Fe derived state is also observed in Fe doped films. Resonance photoelectron spectroscopy studies indicate that Fe ions are hybridized with Ti3+ defect states. (C) 2011 American Institute of Physics. [doi:10.1063/1.3624775]“
“Clinical trials have pointed out the promising role of co-stimulation blocker Belatacept for improvement of graft function and avoidance of undesired side-effects associated with calcineurin-inhibitors (CNI). However, due to the worldwide limited availability of appropriate patients, almost no data exist to assess the effects of sustained application of this immunomodulator on the recipients immune system. The aim of this study was to reveal specific alterations in the composition of immunologic subpopulations potentially involved in development of tolerance or chronic graft rejection following long-term Belatacept therapy. For this, peripheral lymphocyte subsets of kidney recipients treated with Belatacept (n = 5; average 7.8 years) were determined

by flow-cytometry and compared with see more cells from matched patients on CNI (n = 9) and healthy controls (n = 10). T cells capable of producing IL-17 and serum levels of soluble CD30 were quantified. Patients on CNI showed a higher frequency of CD4+CD161+ Th17-precursors and IL-17-producing CD4+ T cells than Belatacept patients and controls. Significantly higher serum levels of soluble CD30 were observed in CNI patients, indicating a possible involvement of the CD30/CD30L-system in Th17-differentiation. No differences were found concerning CD4+CD25+CD127lowFoxP3+ regulatory T cells. In conclusion, patients on therapy with Belatacept did not show a comparable Th17-profile to that seen in individuals with chronic intake of CNI. The distinct effects of Belatacept on Th17-immunity might prove beneficial for the long-term outcome following kidney transplantation.”
