Chronic rhinosinusitis (CRS) is one of the most common persistent disorders developed world, requiring input from various specialists including primary care physicians, otolaryngologists, respiratory and allergologists. B-cell lymphoproliferative (BLPDs) are a heterogenous group malignant conditions defined by an accumulation mature B lymphocytes in bone marrow, blood, lymphoid tissues. We pres...

hematopoietic stem/progenitor cells (hspcs) which give rise to different blood cell types are present within the bone marrow microenvironment, especially in flat bones such as skull, vertebrae, pelvis and chest. interacting factors such as stromal derived factor-1/cxcr4, very late antigen-4/vascular cell adhesion molecule-1, lymphocyte function-associated antigen-1/ intercellular adhesion molec...

conclusions the results of this study showed that the meticulous microsurgical nerve repair, which was performed using the vein tubulization induced significantly better sciatic nerve regeneration. however, the addition of bone marrow mesenchymal stem cell to vein conduit failed to promote any significant changes in regeneration outcome. results all animals tolerated the surgical procedures and...

background: the purpose of this study was to find the accurate absorbed dose in the femur bone marrow during the x-ray radiography for constant mas and aec techniques. materials and methods: the dosxyznrc was used to simulate radiation doses in two human femurs during diagnostic radiography. egsnrc phantoms produced from actual ct images of human femurs were modified by adding seven micrometre ...

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 ...
