background : gestational trophoblastic neoplasia (gtn) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. many attempts have been made to improve follow-up procedures, but no studies have evaluated human chorionic gonadotrophin (hcg) as a post treatment indicator. thus we aimed to know β-hcg variability in post treatment pregnancies.   method...

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...

Let β be the growth exponent of loop-erased random walk (LERW) in three dimensions. We prove that scaling limit 3D LERW is almost surely h-Hölder continuous for all h<1∕β, but not 1∕β-Hölder continuous.

in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...
