Although Iranians had an important impact on the improvement of science, the history of Iranian medicine seems not to have been given enough attention by historians. The present study focused on the history of anesthesia and pain management in Iranian med...

There is large variation in the molecular genetics and clinical features of hemoglobinopathies in Iran. Studying structural variants of hemoglobin demonstrated that the β-chain variants of hemoglobin S and D-Punjab are more prevalent in the Fars (southwestern Iran) and Kermanshah (western Iran) provinces, respectively. Also, α-chain variants of Hb Q-Iran and Hb Setif are prevalent in western Ir...

This review was performed to examine the research evidence suggesting a higher prevalence of non-conventional type 2 diabetes risk factors in Ir...

Geographic or ethnic differences in the occurrence of disease often provide insights into causes of disease and possible opportunities for disease prevention. A wide variation on the incidence and prevalence of PsA was reported in different countries. The prevalence in China was similar to the rest of the world, whereas the incidence and prevalence of PsA was much lower in Japan. Among patients...

BACKGROUND Social health is a dimension of health affected and interacts with other dimensions. Considering the rate of world changes, foresighting the influence of future events and possible trends on social health could bring about advantageous information for social policy makers.

Genetic polymorphisms have been shown to be involved in dopaminergic neurotransmission. This may influence susceptibility to Parkinson's disease (PD). We performed a case-control study of the association between PD susceptibility and a genetic polymorphism of MAOB and COMT, both separately and in combination, in Iranians. The study enrolled 103 Iranian patients with PD and 70 healthy individual...
