A fluid collection around the RF

ablation area was seen in eight of the 10 noncooled kidneys on day 7 CT scans compared with two of the 10 cooled kidneys; the difference was statistically significant (P = .035). Ex vivo retrograde pyelography depicted leakage of contrast material in only the noncooled group. The mean histologic damage score was lower in the cooled group than in the noncooled group.

Conclusion: RF ablation after placement of an antegrade cooling system in pig kidneys was feasible. Antegrade cold dextrose infusion of the urinary tract during RF ablation is effective in protecting the renal collecting system without compromising the RF ablation effect.”
“Oxides RNiO3 (R – rare-earth, R not equal La) exhibit a metal-insulator LY2157299 (MI) transition at a temperature T-MI and an antiferromagnetic (AF) transition at T-N. Specific heat (C-P) and anelastic spectroscopy measurements were performed in samples of Nd1-xEuxNiO3, 0 <= x <= 0.35. For x – 0, a peak in C-P is observed upon cooling and warming at essentially the same temperature T-MI – T-N similar to 195 K, although the

cooling peak is much smaller. For x >= 0.25, differences between the cooling and warming curves are negligible, and two well defined peaks are clearly observed: one at lower temperatures that define T-N, and the other one at T-MI. An external magnetic field of 9 T had no significant effect on these results. The elastic compliance (s) and ICG-001 ic50 the reciprocal of the mechanical quality factor (Q(-1)) of NdNiO3, measured Nocodazole concentration upon warming, showed a very sharp peak at essentially the same temperature obtained from C-P, and no peak is observed upon cooling. The elastic modulus

hardens below T-MI much more sharply upon warming, while the cooling and warming curves are reproducible above T-MI. Conversely, for the sample with x – 0.35, s and Q(-1) curves are very similar upon warming and cooling. The results presented here give credence to the proposition that the MI phase transition changes from first to second order with increasing Eu doping. (C) 2011 American Institute of Physics.

“Nonneoplastic mucocutaneous lesions are frequent in organ transplant recipients. Many of them are caused by a direct toxicity of immunosuppressive drugs, in particular glucocorticoids and cyclosporine. The effects of these agents are dose-and time-dependent. Glucocorticoids can cause acne, Cushingoid appearance, irregular purpuric areas, friable skin, and wide and violaceous stripes. Cyclosporine can cause hypertrichosis, pilosebaceous lesions, and gum hypertrophy. Patients with esthetic changes may show poor adherence to treatment with these immunosuppressive agents that may lead to progressive graft dysfunction.
