Background: We have previously reported the aberrant expression of Fibromodulin (FMOD) in patients with chronic lymphocytic leukemia (CLL). Although FMOD has been considered as a cytoplasmic or secretory protein, we discovered the cell surface expression of FMOD in leukemic B cells via anchoring with glycosylphosphatidylinositol (GPI). Objective: To evaluate FM...

Natural Killer (NK) cells are part of our innate immune system with regulatory and effector functions. Different studies suggest that treatment with intravenous immunoglobulins (IVIg) has an immunomodulatory effect on NK cells. IVIg is a first-line treatment for various autoimmune diseases in particular in chronic inflammatory demyelinating polyneuropathy (CIDP). The lack of predictive markers ...

Background: The diagnosis of B-cell acute lymphoblastic leukemia (B-ALL) on the basis of the World Health Organization (WHO) recommendations in 2016 requires the expression of CD19 with CD79a (CD79a), cCD22 and CD10. CD79a is an integral B cell antigen expressed at all stages. Its absence in B-ALL has only been rarely reported. In this study, we described three cases of B-ALL showing complete l...

objective: leishmaniasis is one of the significant causes of morbidity and mortality in several countries. it is an important problem in endemic areas such as iran. the goal in treatment of leishmaniasis is to reduce the disease period and leave no evidence of any remaining scars or lesions. a derivative of artemisinin is artemether. scientists believe that the strong action of artemether again...

background: myelodysplastic syndrome is a mixed clonal disorder of bone marrow progenitor cells. understanding the pattern of the different lineage-specific, immature, and mature markers in myelodysplastic syndrome will help in setting-up the frame of reference to diagnose. patients and methods: we compared 60 bone marrow samples from 30 newly-diagnosed patients with myelodysplastic syndrome an...

Perturbation of the tubulin/microtubule dynamic in cells is perhaps the single most important mode of action of anticancer drugs. Standard methods for identifying and evaluating compounds for their ability to alter tubulin polymerization are low throughput, labor intensive, expensive, or make their assessment in vitro. Here we report a method to rapidly quantify the extent of tubulin polymeriza...

Flow cytometry is a versatile technique to study different aspects of the cell cycle from subpopulations of cells to detailed cell kinetic information. In this paper a basic review of cell kinetic parameters is presented followed by detailed descriptions of the different flow cytometric methodologies that can be used to extract pertinent information for a particular study. The methodologies ran...

AIM To evaluate a flow cytometry protocol that uses reference beads for the enumeration of live and dead bacteria present in a mixture. METHODS AND RESULTS Mixtures of live and dead Escherichia coli with live:dead concentration ratios varying from 0 to 100% were prepared. These samples were stained using SYTO 9 and propidium iodide and 6-μm reference beads were added. Bacteria present in live...

CONTEXT Accurate quantitation of bone marrow plasma cells is an important component in the diagnosis and posttreatment assessment of plasma cell dyscrasias. Although flow cytometry is sometimes used for this purpose and can rapidly evaluate many cells, the accuracy of flow-based plasma cell quantitation compared with morphologic assessment (currently the gold standard) is uncertain as direct co...
