Polyoma virus nephropathy occurs in 3% to 4% of renal transplant recipients, causing graft loss in 50% of cases. In this study we sought to identify the incidence of polyoma virus infection among our transplanted patients on the basis of age, sex, creatinine level, and postoperative period. During this study the 1086 urine samples collected from 362(More)
Cell therapy and tissue repair are used in a variety of diseases including tissue and organ transplantation, autoimmune diseases and cancers. Now mesenchymal stem cells (MSCs) are an attractive and promising source for cell-based therapy according to their individual characteristics. Soluble factors which are able to induce MSCs migration have a vital role(More)
Platelet-rich plasma (PRP) has been of great concern to the scientists and doctors who are involved in wound healing and regenerative medicine which focuses on repairing and replacing damaged cells and tissues. Growth factors of platelet-rich plasma are cost-effective, available, and is more stable than recombinant human growth factors. Given these valuable(More)
AIM To improve the isolation and expansion of human marrow-derived mesenchymal stem cells (MSCs) based on rat samples. METHODS Based on the fact that rat MSCs are relatively easy to obtain from a small aspirate, bone marrow-derived MSCs from rat were cultured and characterized to set up the different protocols used in this study. Then, accordingly, almost(More)
OBJECTIVE Acute rejection remains an important cause of graft loss after renal transplantation, and cytokines are key mediators in the induction and effector phases of all immune and inflammatory responses. However, the influence of gene polymorphisms on the functional immune response of transplant recipient outcomes remains controversial. MATERIALS AND(More)
Although the precise nature of Antiphospholipid antibodies is still not clearly defined, they are known to have association with thromboembolic events and have been found in hepatitis C virus (HCV) infection. Moreover, high prevalence of HCV infection and thrombotic risk is described in thalassemia. We aimed at investigating the prevalence of(More)
BACKGROUND Malnutrition is highly prevalent in hemodialysis (HD) patients. These patients have high levels of oxidative stress and inflammation which can subsequently induce malnutrition. Selenium levels have been found to be decreased in HD patients. As selenium deficiency leads to oxidative stress and inflammatory response, the aim of this study was to(More)
The ability of MSCs (mesenchymal stem cells) to differentiate between other cell types makes these cells an attractive therapeutic tool for cell transplantation. This project was designed to improve transdifferentiation of human MSCs into liver cells using IGF-I (insulin-like growth factor 1) which, despite its important role in liver development, has not(More)
AIM To improve hepatic differentiation of human mesenchymal stem cell (MSC) using insulin growth factor 1 (IGF-I), which has important role in liver development, hepatocyte differentiation and function. METHODS Bone marrow of healthy donors was aspirated from the iliac crest. The adherent cells expanded rapidly and were maintained with periodic passages(More)
Management of renal transplant patients requires periodic measurement of renal function especially in early post transplant period. This is usually assessed by measuring the creatinine clearance, but because of its limitations, it is not an ideal marker for assessing the renal function. Serum cystatin C (sCyC) appears to be an endogenous marker of(More)
