background: some recent studies reported human epidermal growth factor receptor (her-2/neu) as a marker that can be used in immunological studies of colorectal carcinoma for predicting the prognosis and the treatment. therefore, we aimed to investigate the frequency of her-2 expression in patients with colorectal cancer, and explore the relationship between clinicopathological prognostic factor...

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...

Research has shown that there are significant ethnic variations in the frequency of highly functional mutations in genes coding for metabolic enzymes. However, few studies have examined the frequency distribution of major allelic variations within the population of Iran. The present study focused on the genotype profile of southern Iranians in order to compare the allelic frequencies of CYP2C9,...

floristic studies are fundamental for the applied sciences such as rangelandmanagement and conservation. unique ecological and climatic conditions in the northernkhorasan province (nkp) make it a remarkable habitat for the floristic studies. plant specieswere collected from 50 field sites, representing major habitats of winter and rural rangelands.surveys were conducted during active growth per...
