Ischemia-reperfusion injury is the major cause of delayed graft function in transplanted kidneys, an early event significantly affecting long-term graft function and survival. Several studies in rodents suggest that the alternative pathway of the complement system plays a pivotal role in renal ischemia-reperfusion injury. However, limited information is currently available from humans and larger animals. Here we demonstrated that 30 minutes of ischemia resulted in the induction of C4d/C1q, C4d/MLB, and MBL/MASP-2 deposits in a swine model of ischemia-reperfusion injury. The infusion of C1-inhibitor led to a significant reduction in peritubular capillary and glomerular C4d and C5b-9 deposition. Moreover, complement-inhibiting treatment significantly reduced the numbers of infiltrating CD163 ؉ , SWC3a ؉ , CD4a ؉ , and CD8a

Abstract. Ischemia-reperfusion (I-R) injury in transplanted kidney, a key pathogenic event of delayed graft function (DGF), is characterized by tubular cell apoptosis and interstitial inflammation. Akt-mammalian target of rapamycin-S6k and NF-B-inducing kinase (NIK)-NF-B axis are the two main signaling pathways regulating cell survival and inflammation. Rapamycin, an immunosuppressive drug inhibiting the Akt axis, is associated with a prolonged DGF. The aim of this study was to evaluate Akt and NF-B axis activation in patients who had DGF and received or not rapamycin and in a pig model of I-R and the role of coagulation priming in this setting. In graft biopsies from patients who were not receiving rapamycin, phosphorylated Akt increased in proximal tubular, interstitial, and mesangial cells with a clear nuclear translocation. The same pattern of activation was observed for S6k and NIK.

Introduction The implantation of penile prostheses is an effective option for treating erectile dysfunction (ED), and nowadays it is used to treat those cases where pharmacological agents have not provided a useful result. Aims The primary aim of the present study was to verify the patient and their partner’s satisfaction, in 80 patients who underwent AMS CX 700 prostheses implant in a single center, by the same surgeon, in the period between 2004 and 2008. Methods In the period between March 2004 and May 2008, 80 penile prostheses implantations have been performed. Any information regarding patients has been retrospectively collected consulting their case histories stored in our archive. Each patient was followed postoperatively, and surgical complications were recorded. Main Outcome Measure All the patients entered in this study were contacted by phone by a single operator who asked for their consent to collect information regarding their operation, the use of the prostheses, and the couple satisfaction. Once the consent was obtained, a nine-point questionnaire was administered. Results Seventy-six patients (97%) affirmed to use penile prostheses frequently. Fifty-four patients (69%) and 70 partners (90%) affirmed that they never had problems with the use of the prosthesis and they considered themselves satisfied. Sixty-two patients (79%) answered that this therapeutic method has led to evident improvements in their sexual life. Sixty-two patients (79%) gave a score equal or major than seven and sixty-four partners (82%) gave a score equal or major than seven. All but two patients (97%) reported they would suggest this treatment to other people. Conclusions Penile prosthetic surgery constitutes a valid therapeutic alternative, capable of modifying the prognosis and the course of ED. This consideration is emphasized by the high rate of patients and partner’s satisfaction emerged in our series and in literature.

We found evidence that SPON2 levels were significantly higher in patients with prostate cancer than in healthy individuals. Moreover, this biomarker had better diagnostic performance than serum sarcosine, and percent free-to-total and total prostate specific antigen. This greater accuracy was also present in a subset of patients with normal prostate specific antigen.
