Association of Serum Fetuin-A Levels with Allograft Outcome in Renal Transplant Recipients.

Purpose: To determine serum fetuin-A pattern after renal transplantation and its association with graft outcome.

Materials And Methods: In 41 renal transplant recipients, serum pretransplant fetuin-A levels and serum fetuin-A concentrations on days 7 and 30 after transplantation were measured using the enzyme-linked immunosorbent as­say (ELISA) method. Also, the association between serum fetuin-A levels with clinical and laboratory parameters was evaluated.

Comparison of before and after varicocelectomy levels of nitric oxide in seminal fluid of infertile men.

Background: Since nitric oxide (NO) has an oxidant activity, lower levels following a varicocelectomy may result in better functioning sperm, improved semen quality and consequently higher fertility rates. However, this procedure should be examined in more detail.

Objectives: Accordingly, this study was performed to compare the before and after varicocelectomy levels of NO in the seminal fluid of infertile men.

Comparison of nitric oxide concentration in seminal fluid between infertile patients with and without varicocele and normal fertile men.

Introduction: Elevated nitric oxide (NO) levels have been shown to have toxic effects on sperm function and motility. This study was conducted to compare NO levels in the seminal fluid of infertile men with varicocele with those of infertile and fertile men without varicocele.

Materials And Methods: Semen samples were obtained from 40 infertile men with varicocele (group 1), 40 infertile men without varicocele (group 2), and 40 fertile volunteers without varicocele (group 3).
