X-inactivation is the mechanism by which mammals achieve X-linked gene dosage equivalence between the sexes. This event occurs during the early stages of postimplantation embryonic development when XX females silence one of their two active X chromosomes. Somatic X-inactivation is a random event, and so females are in fact mosaic, comprising two populations of cells, each exhibiting exclusive e...
The clinical efficacy of evaluating genetic anomalies in metaphase cells versus interphase nuclei for multiple myeloma (MM) is poorly understood. Therefore, survival for 154 patients with newly diagnosed untreated MM was compared with results from analysis of metaphase and interphase cells. Metaphases were studied by conventional cytogenetics and fluorescent-labeled DNA probes (fluorescence in ...
The monophyletic carnivorous genus Genlisea (Lentibulariaceae) is characterized by a bi-directional genome size evolution resulting in a 25-fold difference in nuclear DNA content. This is one of the largest ranges found within a genus so far and makes Genlisea an interesting subject to study mechanisms of genome and karyotype evolution. Genlisea nigrocaulis, with 86 Mbp one of the smallest plan...
In this work, the microstructural evolutions and mechanical properties of an as-cast Mg-10Gd-4Y-1.5Zn-0.5Zr (wt %) alloy during successive multi-pass equal channel angular pressing (ECAP) were systematically investigated by X-ray diffractometer, scanning electron microscopy, transmission electron microscopy, and compression test. The obtained results show that the microstructure of as-cast allo...
Safety and security are key aspects for the success of tourism in every destination. Rather than objective risks, it is rather the tourist's individual and subjective perception of these risks that mostly infl uence destination choice and in the long run tourism fl ows from one country to another. Th e concept of risk perception has been highly studied in tourism, however the literature remains...
Stakeholders' perceptions towards tourism development within destinations have been emphasized by researchers and practitioners. However, literature has only focused local residents' role in tourism development, leaving a gap in knowledge on stakeholders' engagement in tourism development process. Th is study investigates stakeholders' perceptions, attitudes and involvement in tourism developme...
Non-syndromic thoracic aortic aneurysms and dissections (TAADs) are inherited in an autosomal dominant manner in approximately 20% of cases. Familial TAAD is genetically heterogeneous and four loci have been mapped for this disease to date, including a locus at 16p for TAAD associated with patent ductus arteriosus (PDA). The defective gene at the 16p locus has recently been identified as the sm...
در این مقاله مطالعه ی تئوری و تجربی پیش بینی نمودار حد شکل دهی آلیاژ آلومینیوم 2024 انجام شده است. جهت به دست آوردن و کالیبره نمودن ضرایب معیار های تسلیم پیشرفته ی yld2004-18p، yld2011-18p، yld2011-27p و bbc2008-16p تست کشش در 7 راستا نسبت به جهت نورد انجام شد. تنش های تسلیم جهتی و ضرایب ناهمسانگردی آلیاژ استخراج گردید. سپس، تابع خطای مناسب تعریف شده و با استفاده از الگوریتم لونبرگ- مارکوات بهی...
