To assess genetic variation in hepatitis C virus (HCV) sequences accurately, we optimized a method for identifying distinct viral clones without determining the nucleotide sequence of each clone. Twelve serum samples were obtained from seven individuals soon after they acquired HCV during a prospective study, and a 452-bp fragment from the E2 region was amplified by reverse transcriptase PCR an...
Marine turtles are increasingly being threatened worldwide by anthropogenic activities. Better understanding of their life cycle, behavior and population structure is imperative for the design of adequate conservation strategies. The mtDNA control region is a fast-evolving matrilineal marker that has been employed in the study of marine turtle populations. We developed and tested a simple molec...
To better investigate Pneumocystis carinii f. sp. hominis epidemiology, we have developed a molecular typing method. Because of the limited genetic variability of the P. carinii hominis genome, a multitarget approach was used. Four variable regions of the genome were amplified by PCR, polymorphism in each region was assessed by the single-strand conformation polymorphism (SSCP) technique, and t...
In this study, 103 unrelated South-American patients with mucopolysaccharidosis type II (MPS II) were investigated aiming at the identification of iduronate-2-sulfatase (IDS) disease causing mutations and the possibility of some insights on the genotype-phenotype correlation The strategy used for genotyping involved the identification of the previously reported inversion/disruption of the IDS g...
A total of 116 isolates from patients attending the out-patient department at the All India Institute of Medical Sciences, New Delhi and the New Delhi Tuberculosis Centre, New Delhi, India were collected. They were analyzed for resistance to drugs prescribed in the treatment for tuberculosis. The drug resistance was initially determined by microbiological techniques. The Bactec 460TB system was...
PURPOSE Varicoceles are associated with impaired testicular function and male infertility, but the molecular mechanisms by which fertility is affected have not been satisfactorily explained. Spermatogenesis might be affected by increased scrotal temperature, such as that caused by varicocele. HSP90 is a molecular chaperone expressed in germ cells and is related to spermatogenesis, motility, and...
چکیده مقدمه: جهش های ژنتیکی با توجه به نقش غیرقابل انکاری که در پیدایش بیماری ها داشته و با تاثیر بر روی کنش های بعدی بیماری، موجب آسیب های بدخیم در پستان می شوند. از آن جمله، جهش نقطه ای در ژن گیرنده استروژن α (esr1)، مانند g908a (لیزین 303 آرژنین) سبب تکثیر بی رویه سلول های حساس به استروژن و رشد تومور در پستان می شود. در این تحقیق ما به شناسایی و غربالگری این جهش در میان زنان ایرانی مبتلا به ...
