75Cr0.25S as is theoretically concluded by previous literature work, while calculations with GGA+U methods predict either antiferromagnetic or ferromagnetic ordering depending on the doping configurations. The appearance Cilengitide purchase of magnetic ordering is rationalized in terms of
the coupling between two adjacent doping Cr atoms that primarily governs the magnetic ordering. Therefore, changing the coupling chains in the Cr-containing semiconductors may provide an alternative route to tune the magnetic properties. (C) 2011 American Institute of Physics.

“Background: This study was carried out to estimate the modification of hydration status within the first three months of renal transplantation.
Subjects and methods: Fifty patients who underwent a first kidney allograft were prospectively followed for three months after renal transplantation to assess hydration status by bioimpedance spectroscopy.
Results: Two hours before the transplant procedure,
10/42 (23.8%) patients were overhydrated. Two days after surgery, 32/40 (80.0%) patients were overhydrated and at three months, 14/27 (51.9%) patients remained fluid-overloaded. Peritoneal dialysis (PD) patients had a lower hydration status (-0.60 L) than hemodialysis (HD) patients (0.70 L; p < 0.05) Dibutyryl-cAMP and better residual diuresis (41.7 vs. 8.3 mL/h for HD patients, p < 0.01). Compared with patients who had a delayed graft function (DGF) or a slow graft function (SGF), the immediate graft function (IGF) group had a better hydration status before transplantation www.selleckchem.com/products/ly333531.html (p = 0.031). At three months,
12/14 of the overhydrated patients had a creatinine clearance between 30 and 60 mL/min/1.73 m(2).
Conclusion: Patients receiving a first kidney transplant frequently have a hydration disorder. Transplantation is associated with increased hydration status, which seems to persist if DGF or SGF occurs.”
“PURPOSE: To compare the outcomes of mechanical and femtosecond laser assisted tunnel creation for intrastromal corneal ring segment (ICRS) implantation in eyes with keratoconus.
SETTING: Kartal Training and Research Hospital, Istanbul. Turkey.
METHODS: In this prospective study, consecutive eyes with keratoconus were randomly assigned to have ICRS tunnel creation with a mechanical device or a femtosecond laser. Keraring ICRS with a 5 0 mm diameter and 160-degree arc length were implanted in all cases The uncorrected (UDVA) and corrected (CDVA) distance visual acuities. refraction, and keratometry (K) readings were measured preoperatively and 1 year postoperatively, and the data in the mechanical group and the femtosecond group were compared statistically
RESULTS: One year postoperatively, there was significant improvement in UDVA, CDVA, K readings, spherical equivalent (SE), and manifest sphere and cylinder in both groups (P< 05) The UDVA improved by 2.4 lines in the mechanical group and 2.
