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...

background: although the pathogenesis of diabetes type 1 (t1d) is not fully elucidated. different clusters of lymphocytes such as cd4+ and cd8+ t cells are involved in it. moreover, the mechanism of how stem-cell therapy results in significant therapeutic outcomes in diabetes remains obscure. in the current study, we aimed to analyze lymphocyte subsets in patients with t1d before and after trea...

The heterogeneous nature of cell types in the testis and the absence of meiotic cell culture models have been significant hurdles to the study of the unique differentiation programs that are manifest during meiosis. Two principal methods have been developed to purify, to varying degrees, various meiotic fractions from both adult and immature animals: elutriation or Staput (sedimentation) using ...

Rheum turkestanicum Janischew. (Polygonaceae) is a plant that grows in central Asia and in north-east of Iran. Traditionally, people use roots of R. turkestanicum as an anti-diabetic and anti-hypertensive as well as anticancer agent. In this study the cytotoxicity and apoptogenic properties of ethyl acetate (EtOAc), n-hexane and H2O extracts from Rheum turkestanicum Janischew. (Polygonaceae) ro...

Despite the toxic effects on numerous organs, silver nanoparticles can be used to cease cell cycle and promotes apoptosis in cancerous cells. Therefore, by choosing the right dosage nanoparticles can be helpful for cancer treatment, whilst do not harm normal tissues. In the current study, it has been tried to measure silver nanoparticles toxicity against HPB-ALL leukemia cell line and normal hu...
