Molecular biology of prions.
The "protein only" hypothesis holds that the infectious agent causing transmissible spongiform encephalopathies is a conformational isomer of PrP, a host protein predominantly expressed in brain and is strongly supported by many lines of evidence. Prion diseases are so far unique among conformational diseases in that they are transmissible, not only experimentally but also by natural routes, ma...
متن کاملthe pathology of historical texts translation: a study of persian translations of 7th volume of cambridge history of iran
ترجمه با گسترش زبان آغاز شده و اهمیت آن روز به روز افزایش می یابد، و برای اولین بار به عنوان شاخه ای از دانش و روشی برای انتقال علوم، فرهنگ و تجربه در در دوره قاجار در ایران آغاز شد. در حقیقت متون تاریخی از اولین متونی هستند که در ایران ترجمه شدند چرا که به سیاستمداران آن دوره کمک می کردند تا به علل موفقیت جهان غرب و پیشرفت هایشان در طول تاریخ پی ببرند، بنابراین به تدریج ترجمه این گونه متون رون...
15 صفحه اولPrions and the new molecular phenetics.
P rions were injected into the public consciousness earlier this year when the British Government’s Health Secretary, Stephen Dorrell, rose in the House of Commons to make his dramatic announcement that the ‘most likely’ explanation for ten cases of a Creutzfeldt-Jakob disease-like (CJD) illness in young people was exposure to British beef that had been infected with the agent causing bovine sp...
متن کاملMolecular Barriers to Zoonotic Transmission of Prions
The risks posed to human health by individual animal prion diseases cannot be determined a priori and are difficult to address empirically. The fundamental event in prion disease pathogenesis is thought to be the seeded conversion of normal prion protein to its pathologic isoform. We used a rapid molecular conversion assay (protein misfolding cyclic amplification) to test whether brain homogena...
متن کاملMolecular pathology of sarcomas.
Bone and soft tissue sarcomas are an infrequent group of tumours with a prevalence of 4 in 100,000 people/year. Sarcomas, such as synovial sarcoma, Ewing's sarcoma and osteosarcoma, are more usual in adolescents or in young adults. Neoplasias such as leiomyosarcoma or liposarcoma are more frequent in patients over 55 years. One relevant topic is related to sarcomagenesis elucidation, a key for ...
