wuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
15 صفحه اولthe study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region
چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولPrenatal diagnosis of steroid 21-hydroxylase deficiency by the modified polymerase chain reaction to detect splice site mutation in the CYP21 gene.
A splicing junction mutation at nucleotide 656 (A-> G substitution, I2G) in the steroid 21-hydroxylase gene (CYP21) is the most frequently detected mutation in patients with the salt-wasting and simple-virilizing forms of steroid 21-hydroxylase deficiency (approximately 60%). In this disease, prenatal diagnosis and treatment to minimize the effects of excess androgen in affected females has bee...
متن کاملMutation screening in British 21-hydroxylase deficiency families and development of novel microsatellite based approaches to prenatal diagnosis.
21-hydroxylase deficiency is a recessively inherited disorder of steroidogenesis, resulting from mutations in the CYP21 gene. This 3.5 kb gene and a highly related CYP21P pseudogene reside on tandemly duplicated 30 kb segments of DNA in the class III HLA region, and the great majority of pathogenic mutations result from sequence exchanges involving the duplicated units. We now describe a compre...
متن کاملComprehensive analytical strategy for mutation screening in 21-hydroxylase deficiency.
Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease with a wide range of clinical manifestations. It is most often caused by deficiency of steroid 21-hydroxylase, reflecting any of a wide range of mutations in the 21-hydroxylase (CYP21) gene. A major challenge in molecular diagnostics of CAH is the high homology between the CYP21 gene and the CYP21P pseudogene and the phenome...
