introduction: the majority of leukemia patients are acute leukemia patients, so that about 70.8% lymphoblastic leukemia were acute lymphoblastic leukemia (all) patients and 66.4 % of myeloid leukemia patients were acute myeloid leukemia (aml) in tehran metropolitan. during the last two decades, intensification of therapy by the use of high-dose cytarabine allogeneic stem cell transplantation in...

Autologous bone marrow transplants for solid tumor treatment are severely limited by the potential presence of residual cancer cells in the reinfused bone marrow and can lead to future tumor recurrence. This article presents a novel method of removing carcinoma cells from bone marrow with contaminating cancer cells. This method is based on our previous studies demonstrating that carcinoma cells...

Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...

Sunitinib is an oral tyrosine kinase inhibitor which prevents tumor growth and metastatic progression. It was approved for treatment of advanced renal cell cancer, gastrointestinal stromal tumor and advanced pancreatic neuroendocrine tumors. It has several adverse reactions on multi organ systems including hematologic system. Although the neutropenia and thrombocytopenia commonly happens as Gra...

Acute lymphocytic leukemia (ALL) is one of the frequent malignancies in pediatrics and involves bone marrow and extramedullary sites. Proptosis as extramedullary involvement of leukemia usually present in acute and chronic myeloid leukemia. It is extremely rare for ALL to present initially as proptosis.Here, a-21-month-old boy was presented with proptosis without any associated symptoms except ...

BACKGROUND: Bone marrow-derived mesenchymal cellscan transdifferentiate into Cardiomyocyte cells and improveheart function after transplantation. Since biomaterials canimprove the cell retention in the site, cell survival and differentiation,heart tissue engineering is now being explored as anapplied solution to support cell-based therapies and increasetheir efficacy for myocardial diseases. Ch...

objective: multiple myeloma (mm) is a plasma cell malignancy where plasma cells are increased in the bone marrow (bm) and usually do not enter peripheral blood, but produce harmful factors creating problems in these patients (e.g. malignant plasma cells over activate osteoclasts and inhibit osteoblasts with factors like rankl and dkk). these factors are a main cause of bone lesion in mm patient...

introduction : use of adipose-derived stem cells (adscs) is a suggested hypothesis to enhance the regeneration of bone defects. this technique is of particular interest since adscs are more easily accessible via a non-invasive harvesting technique compared to bone marrow stem cells (bmscs). this study sought to assess the efficacy of adsc implantation for regeneration of localized mandibular bo...

Myelodysplastic syndrome (MDS) is a set of clonal bone marrow diseases in children that are characterised by peripheral cytopenia, dysplastic alterations the marrow, and inefficient hematopoiesis. MDS uncommon children, with just 1-4 occurrences per million afflicted. Adults, particularly elderly, more susceptible to disease. Some hereditary disorders, such as Fanconi's anaemia, Shwachman's, Do...
