Currently, there are 18 dental schools with a total admission of 750 undergraduate students, 5 postgraduate programs in 10 disciplines with a total of 100 students, more than 11,000 dentists (1 dentist pe...

the cd1 family is less variable transmembrane antigen presenting molecules related to the mhc molecules. cd1a and cd1e genes are the most polymorphic ones associated with autoimmune diseases. the aim was to better clarify the map of cd1 genes in southwest iranian normal population for implications in vaccine design.in this study we investigated the polymorphism of cd1a, cd1d and cd1e in 311 hea...

conclusions our study suggested that the prevalence rate of hepatitis c virus is below 1% in the general population of mashhad. results in this study the overall seroprevalence of hepatitis c was founded to be 0.2% by using elisa method. however, the overall hepatitis c virus infection prevalence was found to be 0.13% with rt-pcr method. patients and methods three thousand, eight hundred and se...

There is several evidence suggests that thrombophilic gene polymorphisms may influence susceptibility to thromboembolic events. The prevalence of these polymorphisms is different in various races and ethnics. Accordingly, we studied the prevalence of Factor V (G1691A and A4070G), prothrombin G20210A and PAI-1 4G/5G in healthy northwest population of Iran. In this prospective study, 500 healthy ...

angiotensin converting enzyme (ace; omim: 106180) has an important role in the conversion of angiotensin i to angiotensin ii and degradation of bradykinin. genetic polymorphism i/d (rs4646994) in the gene encoding ace has been well defined. to get more insight into the genetic structure of iranian populations, the distribution of the ace i/d polymorphism among iranians was compared with each ot...
