background the aim of this clinical trial was the assessment of safety and efficacy of submocosal and periurethral injections of peripheral blood derived autologous stem cells along with platelets, and focused on outcome for six months. methods an open, prospective study was conducted on 10 patients presenting with stress urinary incontinence. at the baseline (pre-operative), 1, 3 and 6 months ...

background: benzene is one of the important occupational pollutants. there are some reports about the leukemogenic effects related to low-level exposure to benzene. objective: to study the frequency of micronucleus (mn), nucleoplasmic bridge (nb), and nuclear budding (nbud) in the peripheral blood lymphocytes of petrochemical workers with low level exposure to benzene. methods: we enrolled 50 w...

introduction : myeloproliferative neoplasms (mpns) are a group of clonal malignant hematologic disease, where the main and common members are; polycythemia vera (pv), primary myelofibrosis (pmf), and essential thrombocytosis (et). these group of diseases are able to be transformed into each other. methods:   this cross sectional study conducted the evaluation of jak2v161f mutation in dna in per...

Background: Alteration in peripheral blood lymphocytes (PBLs) is usually investigated to provide an evidence of the host immune responses to tumor antigens. The tumor infiltrating NK cells interact most closely with the tumor cells and more accurately reflect tumor host interactions. Objective: To analyze peripheral blood and tumor associated Natural Killer (NK) cells in patients with breast ca...

background: activated platelets shed microparticles (mps) in vivo and certainly in vitro under storage. like platelets, platelet-derived mps contribute to hemostatic and inflammatory responses. we sought to determine the interactions between platelet mps and peripheral b lymphocytes in the healthy blood circulation to propose a possible role for platelet mps in the functioning of b cells.   mat...

background: exposure to ionizing radiation results in genotoxicity and the unrepaired lesions in cellular dna results in cell cycle arrest, reproductive death, interphase death, division delay, chromosome aberrations, mutations, etc. leading to the intensive destruction of cells and violation of their proliferative capacity there by adversely affecting the mammalian system. since ionizing radia...

introduction: enrichment of intact peripheral blood dendritic cells (dcs) has been done using rosette and immunomagnetic depletion techniques. material and methods: peripheral blood mononuclear cells were separated using ficoll density gradient centrifugation and t lymphocytes were depleted through reaction with aet- treated sheep red blood cells. the remaining cells were depleted from lineage ...
