Behcet’s disease

Authers: Fereydoun DAVATCHI1, 2, 3, 4

Abstract: neurological manifestations and positive pathergy tests each get one point. Oral aphthosis, genital aphthosis and ocular lesions each get two points. To be classified/ diagnosed as BD, a patient has to get four points (or more). Behcet’s disease manifestations are self-limiting, but recurrent. Some heal without a sequelae, but others are the main cause of morbidity, such as ophthalmological manifestations which may cause blindness if not aggressively treated. Some may cause mortality, as in some of the vascular, neurological, cardiac ... Publish year: 2014

Authers: Elham Karimizadeh • Nasrin Motamed • Mahdi Mahmoudi • Saeideh Jafarinejad-Farsangi • Ahmadreza Jamshidi • Habibeh Faridani • Farhad Gharibdoost

Abstract: Cellular abelson (c-Abl), a non-receptor tyrosine kinase, is an important molecule in the pathogenesis of systemic sclerosis. There have been reports of beneficial effects of pharmacological tyrosine kinase inhibitors, such as imatinib mesylate, on fibrosis. However, these inhibitors affect multiple tyrosine kinases including c-Abl, c-kit, and platelet-derived growth factor receptor. The effects of selective inhibition of c-Abl using small interfering RNA (siRNA) on dermal fibrosis have not yet been explored. The aim of this study is to evaluate whether ... Publish year: 2014
