واکنش بیجینلی اولین بار در سال 1893 توسط پیترو بیجینلی انجام شد. این واکنش، یک واکنش چند جزئی ساده و مفید برای سنتز دی هیدرو پیریمیدینون ها با استفاده از αو β- کتو استرها، آلدهید ها و اوره یا تیو اوره در حضور اسید های لوئیس یا اسید های معدنی است. دی هیدرو پیریمیدینون ها در سالهای اخیر، به دلیل خواص دارویی و درمانی زیاد از جمله خواص ضدویروسی، ضد باکتریایی، کاهش دهنده فشار خون و ضد توموری توجها...

Abstract Introduction During laboratory-based, voluntary exposure to total sleep deprivation (TSD), relatively large decreases in positive mood and small increases negative have been observed, with the magnitudes of change varying across individuals. People differ their trait emotion reactivity, i.e., sensitivity emotion-evoking stimuli or events. As higher reactivity is associated greater diff...

objective: β-thalassemia is caused by absence or reduction of β-globin chain synthesis. one of the effective therapeutic methods for this disease can be gene therapy by viral vectors. the capacity of lentiviral vectors is approximately 8 kb, we designed a 6 kb construct containing mini lcr and β-globin gene instead of lcr region. the aim of this study is to make a recombinant lentiviruses conta...

This paper proposes an efficient H.264/AVC entropy decoder. It requires no ROM/RAM fabrication process that decreases fabrication cost and increases operation speed. It was achieved by optimizing lookup tables and internal buffers, which significantly improves area, speed, and power. The proposed entropy decoder does not exploit embedded processor for bitstream manipulation, which also improves...

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...
