background: many efforts have been undertaken until now to find an alternative approach to packed red cell tranfusion in major β-thalassemia. augmentation of fetal hemoglobin by hydroxyurea has proved to be less effective in this condition as compared to sickle cell anemia, probably due to molecular heterogeneity of the former disease. hydroxyurea efficacy and its relation to xmn1 polymorphism ...

background: mutations in β -globin gene may result in β-thalassemia major, which is one of the most common genetic dis­or­ders in iran and some other countries. knowing the beta-globin mutation spectrum improves the efficiency of prenatal diagno­sis in the affected fetuses (major β-thalassemia) of heterozygote couples. methods: couples with high hemoglobin a 2 and low mean corpuscular volume we...

Three distinct viologen derivatives have been designed and successively synthesized. They are shown to form 1:1 or 2:1 host−guest inclusion complexes with β-cyclodextrin (β-CD) in aqueous solution. In comparison with...

introduction: the purpose of this study was to evaluated the effect of β-mercaptoethanol on resumption of meiosis, in vitro maturation of immature mouse oocytes and resulting embryo development with and without bso (dl-buthionine sulfoximine). material and methods: germinal vasicle (gv) were recovered from 6-8 weeks old nmri ovaries and cultured in maturation medium in memα supplemented with 7....
