introduction: while human endothelial progenitor cells (epcs) have been a subject of somehow extensive investigation, epcs from adult mouse hematopoietic system were poorly studied. present investigation is focused on fvb mouse endothelial progenitor cells in terms of their isolation, purification, and expansion. materials and methods: mononuclear cells collected from murine peripheral blood we...
objective(s) human umbilical cord blood (hucb) is now considered as a valuable source for stem cell–based therapies. previous studies showed that intravascular injection of the hucb significantly improves neurological functional recovery in a rat model of intracerebral hemorrhage (ich). in the present study, we hypothesize transplanted hucb derived mononuclear cells (uc-mcs) can decrease injure...
results of 45 patients, 4 (8.9% [95% ci: 4.4-15.6]) had detectable genomic hcv-rna in their pbmc specimens. hcv genotypes were determined in the pbmcs of these subjects showed that 2 (50.0%) subjects with occult hcv infection had hcv subtype 3a, and 2 (50.0%) had hcv subtype 1b. conclusions this study found that 8.9 % of the iranian candidates for liver transplant with cryptogenic cirrhosis had...
abstract background: cholesterol cleft granulomas with clusters of giant cells were noted to be a common feature of non-specific interstitial pneumonia (nsip). objective: this study aimed to define the cell populations involved in the granulomas. methods: the granulomas of 16 patients with cryptogenic fibrosing alveolitis (five cases with the histological features ofnsip, five with those ofuip ...
Background and Objective: Cancers are among the serious problems in communities. In recent years, herbal products have been very promising regarding their anti-tumor and immunomodulatin potentials. SIM5, a herbal preparation, has had good results in discriminating between cancerous cell lines and normal cells, but have not examined directly on patients cells yet. In this study, bone marrow mono...
Introduction: Regarding the increasing use of silicon dioxide nanoparticles in medical biotechnology and probable side effects and diseases resulting from its usage, this study was performed to assess the toxic effects of different concentrations of SiO2 nanoparticles on human blood mononuclear leukocytes using the MTT assay. Methods: In this laboratory trial study, we prepared suspensions of...
Background & Objective: In previous studies, the effects of food restriction on the changes in immune responses and brain dopamine content have been determined. On the other hand, it has been shown that immune cells, in addition to dopamine production, also have dopamine receptors. The purpose of this study was to evaluate the effect of inhibition of D2 dopamine receptors on several functions o...
Introduction: The extended use of nanoparticles has increased and public concern about possible adverse health effects of exposure to this substance is growing. This study was conducted to assess the cytotoxic effects of different concentrations of MgO nanoparticles on human blood mononuclear cells. Methods: In this laboratory trial study, suspensions of blood mononuclear cells were prepared f...
introduction: umbilical cord blood is a rich source of hematopoietic cells and can be used in the clinical setting for hematopoietic cell transplantation in graft versus host disease (gvhd). a number of different drugs have been used as prophylaxis against gvhd including corticosteroids, cyclosporine a (cy a) and fk506. in this study, the in vitro effects of fk506 on cord blood mononuclear cell...
Background and Aims: The aim of this study was to synthesize antibody-conjugated radioactive(thorium oxide) nanoparticles (ACRNPs) and folic acid-conjugated radioactive nanoparticles (FACRNPs). Materials and Methods: After synthesis of nanoparticles, blood samples from CLL patients and normal subjects were obtained, and their mononuclear cells were isolated by Ficoll method. To evaluate cyto...
