introduction: it is an unfamiliar, frightening and stressful experience for the parents of a child who is undergoing bone marrow transplantation. it is impossible to propose an effective caring method without considering all dimensions related to such experience. objective: the purpose of this study was to describe and understand the lived experiences of parents whose children were undergoing b...

background: chronic graft versus host disease (cgvhd) is one of the most serious potential complications of allogeneic bone marrow transplantation. study design and method: we analyzed the incidence of cgvhd and its associated risk factors in a group of 161 iranian recipients of hla-identical sibling transplants, with at least 90 days post-transplantation survival. in the majority of cases (n=7...

background: silk fibroin is a suitable protein for osteogenesis by inducing markers of bone formation in the cultures of osteoblasts, so we examined the ability of this protein to induce mineralized nodules in the rat bone marrow stromal cell cultures. methods: bone marrow stromal cells obtained from 4 to 6 weeks old spruge-dawely male rats were grown in primary culture for seven days and then ...

abstract background this study aimed to compare sedative and analgesic effects of oral midazolam and ketamine on bone marrow aspiration (bma) and lumbar puncture (lp). material and methods this study was a randomized clinical trial and was performed in amirkola hospital in north of iran, babol during 2011 and 2012 .the study population consisted of 40 patients who underwent the first time of di...

introduction: sox9 is a transcriptional activator which is necessary for chondrogenesis. sox6 are closely related to dna-binding proteins that critically enhance its function. therefore, to carry out the growth plate chondrocyte differentiation program, sox9 and sox6 collaborate genomewide. chondrocyte differentiation is also known to be promoted by glucocorticoids through unknown molecular mec...

introduction: bone marrow (bm) is a known source of mesenchymal stem cells (mscs) that are used for cell therapy. this study attempts to identify if the wharton’s jelly (wj) is a suitable substitute for bm as a source for mscs. materials and methods: a population of human wj and bm stem cells were isolated and incubated with fluorescein conjugated antibodies for five specific msc markers. cell ...

Background: Acute myeloid leukemia (AML) is characterized by the proliferation of myeloid precursors and abnormal differentiation of hematopoietic stem cells, which results in the accumulation of immature cells in the bone marrow (BM). The accumulation of these cells in the bone marrow causes molecular and cellular changes in the microenvironment of the bone marrow. The adiponectin hormone orig...

Enhanced cellular DNA repair efficiency and suppression of genomic instability have been proposed as mechanisms underlying radio-adaptive responses following low-dose radiation exposures. We previously showed that low-dose γ irradiation does not generate radio-adaptation by lowering radiation-induced cytogenetic damage in mouse spleen. Since radiation may exert tissue-specific effects, we exten...

The reports regarding the mutual influence between the central nervous system and the immune system constitute a vast and somewhat controversial body of literature. Stress is known to disturb homeostasis, impairing immunological functions. In this study, we investigated the hematopoietic response of Chlorella vulgaris (CV)-treated mice exposed to single (SST) and repeated stress (RST). We obser...

introduction: there are the evidences to suggest that bone marrow stromal cells (bmscs) not only differentiate into mesodermal cells, but also adopt the fate of endodermal and ectodermal cell types. bmscs can be a valuable cell source as an autograph for clinical application involving regeneration of the central nervous system. bone marrow stromal cells can be expanded rapidly in vitro and have...
