Ex-vivo donor partial nephrectomy at the time of donor-directed renal transplantation.

The outcome of nephron-sparing surgical management of small renal masses is generally favorable, specifically in terms of long term renal function, overall survival, and oncologic outcomes. Given the overall prognosis and renal function preservation, transplantation of kidneys with small renal masses has increasingly been accepted as a donor option for renal transplantation. We present a case of an incidental renal mass on preoperative donor transplant evaluation and subsequent ex-vivo donor partial nephrectomy at the time of renal transplantation.

MPGN and mixed cryoglobulinemia in a patient with hepatitis C - new treatment implications and renal outcomes.

Introduction: The association of hepatitis C virus (HCV), cryoglobulinemia, and membranoproliferative glomerulonephritis (MPGN) is well known. Treatment of underlying HCV infection has greatly improved in recent years with the introduction of direct-acting antivirals (DAA), which have demonstrated curative sustained viral response (SVR) rates for select viral genotypes with the added benefit of less drug side effects. However, a mainstay of newer DAAs is sofosbuvir, which is contraindicated in patients with severe renal impairment.

Nanostructured copper oxide on silica-zirconia mixed oxides by chemical implantation.

N,N-Dialkylcarbamato complexes of copper(II), [Cu(O(2)CNR(2))(2)] (R = All = allyl, C(3)H(5); iPr, CH(CH(3))(2)) were prepared with the aim of functionalizing silica and nanostructured silica-zirconia matrices. The mixed matrices for the grafting reactions were prepared by copolymerizing MAPTMS (methacryloxypropyltrimethoxysilane), the precursor for the silica matrix, with the zirconium tetranuclear derivative [Zr(4)O(2)(OMc)(12)] (OMc = methacrylate), the precursor for the zirconia nanoparticles. Suspension of the silica and silica-zirconia matrices in a solution of the copper dialkylcarbamate led to the functionalization of the respective substrates.

Halide ligand-more than just sigma-donors? A structural and spectroscopic study of homologous organonickel complexes.

The isoleptic organonickel complexes [(bpy)Ni(Mes)X] (bpy ) 2,2'-bipyridine; Mes ) 2,4,6-trimethylphenyl; X ) F,Cl, Br, or I, and for comparison X ) OMe and SCN) have been investigated by multiple spectroscopic means.Their structures have been determined in part by single-crystal X-ray diffraction, the full series by extended X-ray absorption fine structure. The long-wavelength charge transfer absorptions (mainly metal-to-ligand charge transfer)obtain contributions from the mesityl coligand but are almost invariable upon variation of X.
