Expression of receptor activator of nuclear factor-kappa B ligand in leukocytes during acute kidney rejection after transplantation in rats.

Background: Acute cellular rejection of the transplanted kidney is an important cause of impaired graft function. One of the basic characteristics of acute cellular rejection according to the latest Banff classification of renal allograft pathology is the presence of a large number of T lymphocytes in the allografted tissue. Osteoprotegerin, receptor activator of nuclear factor-kappa B (RANK) and RANK ligand (RANKL), three relatively novel members of the tumor necrosis factor superfamily, have crucial roles not only in physiologic and pathologic bone metabolism but also in immunologic processes.

[Kidney transplantation--a successful story started 110 years ago].

Organ transplantation is one of the most important medical achievement of the 20th century. Emerich Ullmann performed on March 7th 1902, in the Vienna, the first successful kidney transplantation. It was an autotransplantation in a dog, with a transposition of a kidney in the neck region.

The association between the recurrence of solitary non-muscle invasive bladder cancer and tumor infiltrating lymphocytes.

Aim: To evaluate whether tumor infiltrating lymphocytes (TIL) in biopsy specimens are associated with the clinical outcome of non-muscle invasive bladder cancer.

Methods: We retrieved tumor specimens from 115 patients with solitary papillary non-muscle invasive bladder cancer treated between 1996 and 2006 and constructed tissue microarrays. Patients were divided in two groups: those with recurrent disease (N=69) and those without recurrent disease (N=46) during the follow up of minimum 5 years.

Lower cyclooxygenase-2 expression is associated with recurrence of solitary non-muscle invasive bladder carcinoma.

Background: A new modality is necessary to prevent recurrence of superficial bladder cancer after complete transurethral resection because of the high recurrence rate even with current prophylaxis protocols.

Methods: In order to analyze the predictive value of cyclooxygenase-2 (COX-2) expression and tumor infiltrating lymphocytes (TILs) in recurrence of this disease tumor specimens from 127 patients with solitary papillary non-muscle invasive bladder cancer (NMIBC), 78 with recurrent disease and 49 without recurrence during follow up of minimum 5 years, were retrieved for tissue microarrays construction and immunohistochemical analysis. COX-2 expression was scored according to Allred's scoring protocol, while presence of TILs was categorized as absent (no) or present (yes) on whole tissue sections.

Bone morphogenetic protein-7 reduces cold ischemic injury in rat kidney.

Background: Deceased donor kidneys have a high incidence of delayed graft function attributable to ischemia-reperfusion injury. Although preservation solution and cold storage reduce cold ischemic injury, the depletion of cellular energy and oxidative signalling leads to cellular damage. Because bone morphogenetic protein-7 has renoprotective effect, we have hypothesized that recombinant human bone morphogenetic protein-7 (rh BMP-7) will better preserve kidney tissue exposed to prolonged cold ischemia in comparison with University of Wisconsin (UW) solution.

mRNA expression of bone morphogenetic proteins and their receptors in human renal cell carcinoma.

Introduction: Bone morphogenetic proteins (BMPs) have been studied in several cancers, but only limited information is available about renal cell carcinomas (RCCs). We determined the expression of mRNA of several BMP ligands and BMP receptors (BMPRs) in healthy kidney tissue and RCCs, and data were compared to clinicopathological parameters.

Material And Methods: Sixty-four samples of RCCs and healthy renal tissues were prospectively examined.
