An experimental study on effects of pyrrolidine dithiocarbamate on ischemia-reperfusion injury in testis.

Introduction: The aim of this experimental study was to investigate the histopathological and biochemical effects of pyrrolidine dithiocarbamate, an antioxidant and inhibitor of NF-kβ, on ischemiareperfusion injury in rats.

Methods: A total of 21 male Wistar-Albino rats were randomly distributed into three groups as sham group (Group 1), ischemia-reperfusion (I/R) group (Group 2) and I/R with pyrrolidine dithiocarbamate (PDTC) group (Group 3). Left testicles of rats in Groups 2 and 3 underwent testicular torsion of 720° for four hours and 100 mg/kg of PDTC was administered intraperitoneally prior to detorsion in Group 3.

Evaluation of different p16 immunostaining methods and the prognostic role of p16/Ki-67 combined expression in non-muscle invasive bladder cancers.

There are many scoring methods evaluating the expression of p16 in the bladder immunohistochemically. In this study our aim was to determine an optimal p16 scoring method by discussing different staining methods related with p16 expression in bladder cancers and to establish the association of p16 and Ki-67 expressions, alone or in combination, with recurrence and progression. Ninety patients undergoing their first transurethral resection for bladder cancer and newly diagnosed papillary urothelial carcinoma (pTa and pT1) were included in the study.

Neutrophil-lymphocyte ratio as a predictor of recurrence and progression in patients with high-grade pT1 bladder cancer.

Introduction: We investigated the value of the preoperative neutrophil-lymphocyte ratio (NLR) in predicting recurrence and progression of high-grade pT1 non-muscle-invasive tumour in patients with bladder cancer during a 5-year follow-up period.

Methods: We retrospectively reviewed data of 1100 patients with bladder cancer; these patients underwent transurethral resection and were monitored at multiple centres from 2008 to 2013. In total, 166 consecutive and newly diagnosed patients with high-grade pT1 tumours were included in this study.

Effect of mitomycin, bevacizumab, and 5-Fluorouracil to inhibit urethral fibrosis in a rabbit model.

Background And Purpose: Mitomycin C (MMC), bevacizumab, and 5-fluorouracil (5-FU) are frequently used in cancer treatment. Each of these agents also exhibits antiproliferative properties in different tissues. We compared the efficacy of MMC, bevacizumab, and 5-FU may inhibit urethral fibrosis (UF) without statistically significant differences among them.

Endothelial nitric oxide synthase gene polymorphisms (promoter -786T/C, exon 894 G/T and intron G10T) in unexplained female infertility.

Background/aims: Recent investigations in both males and females show that there may also be some genetic risk factors associated with infertility, and endothelial nitric oxide synthase (eNOS) has important functions in implantation. We aimed to investigate the association of three different polymorphisms of eNOS (promoter -786T/C, exon 894 G/T and intron G10T) with unexplained female infertility.

Materials And Methods: Two groups of patients were included in the study: (1) women with unexplained infertility and (2) healthy, fertile women with normal menstrual cycles.

Protective effects of N-acetylcysteine on experimentally undescended testis.

Purpose: We evaluated the efficacy of N-acetylcysteine for testicular damage induced by undescended testes in rats.

Materials And Methods: Flutamide was injected in the abdomen of pregnant rats daily from days 14 to 20 of gestation. Male offspring with cryptorchidism were randomly divided into 2 groups.

Expression of NOS isoforms in internal spermatic veins of infertile men with varicocele.

Although varicocele is a relatively common entity encountered in the evaluation of infertile men, the exact pathophysiology still remains unclear. Recently, as previously widely investigated in various parts of human circulatory system, nitric oxide synthase (NOS) and its product, nitric oxide (NO) have been thought to play a role in the development of varicocele and thus male infertility. In this study, we determined the concentration of NO metabolite and the expression of NOS isoforms in the internal spermatic (ISV) and superficial branch of inferior epigastric veins of infertile men with varicocele.
