BACKGROUND A hot new topic in medical treatment is the use of mesenchymal stem cells (MSC) in therapy. The low frequency of this subpopulation of stem cells in bone marrow (BM) necessitates their in vitro expansion prior to clinical use. We evaluated the effect of long term culture on the senescence of these cells. RESULTS The mean long term culture was(More)
We analyzed the outcomes of 485 patients with thalassemia major (TM) or sickle cell disease (SCD) receiving HLA-identical sibling cord blood transplantation (CBT, n = 96) or bone marrow transplantation (BMT, n = 389). Compared with patients given BMT, CBT recipients were significantly younger (median age 6 vs 8 years, P = .02), and were treated more(More)
PURPOSE The long-term follow-up results of patients with acute promyelocytic leukemia (APL) treated with all-trans retinoic acid and chemotherapy show high cure rates. Several studies have shown high efficacy of single-agent arsenic trioxide in newly diagnosed APL. However, long-term follow-up results are needed. PATIENTS AND METHODS One hundred(More)
Prostate cancer is the frequent non-cutaneous tumor with high mortality in men. Prostate tumors contain cells with different status of androgen receptor. Androgen receptor plays important roles in progression and treatment of prostate cancer. Aurora B kinase, with oncogenic potential, is involved in chromosome segregation and cytokinesis, and its inhibition(More)
BACKGROUND & AIMS There has been great interest in recent years to take advantage of bone marrow stem cells to treat cirrhosis. Our uncontrolled trial showed promising results for bone marrow mesenchymal stem cell (MSC) transplantation in cirrhosis. Therefore, we conducted a randomized, placebo-controlled trial to evaluate the efficacy of autologous MSC(More)
Busulfan and cyclophosphamide (BuCy) are currently the most widely used myeloablative regimen to treat malignancies with allogeneic stem cell transplantation. Fludarabine has considerable efficacy in both immunosuppression and tumor cells killing with a minimal extramedullary toxicity. We evaluated the efficacy of 40 mg/m(2) fludarabine i.v. for 5 days and(More)
BACKGROUND Promising reports exist regarding the use of arsenic trioxide (ATO) as first-line treatment in acute promyelocytic leukemia (APL). Although the in vitro effect of ATO is extensively studied, the in vivo mechanism(s) of ATO action is mostly unknown. PATIENTS AND METHODS Newly diagnosed APL patients were involved and received ATO (0.15 mg.kg/day)(More)
Oral mucositis (OM) is a complication of high-dose chemotherapy (HDC) followed by hematopoietic SCT (HSCT) with few effective treatments. Selenium has a cytoprotective role via the glutathione peroxidase (Glu.Px) enzyme and prevents chemotherapy-induced toxicities. We performed a double-blind, randomized, placebo-controlled study to evaluate the efficacy of(More)
The purpose of this study was to evaluate the effect of oral zinc sulfate in the prevention of chemotherapy-induced mucositis in patients undergoing hematopoietic stem-cell transplantation (HSCT). This study was a double-blind, randomized, placebo-controlled design, with 60 patients undergoing HSCT, divided proportionally in experimental group who received(More)
