BACKGROUND Propolis (bee glue) has been used as a remedy since ancient times. Propolis from unexplored regions attracts the attention of scientists in the search for new bioactive molecules. RESULTS From Iranian propolis from the Isfahan province, five individual components were isolated: the prenylated coumarin suberosin 1, and four terpene esters: tschimgin (bornyl p-hydroxybenzoate) 2, tsc...

In recent years, most of the regions in the world are exposed to degradation and erosion caused by increasing population and over use of land resources. The understanding of the most important factors on soil erosion and sediment yield are the main keys for decision making and planning. In this study, the sediment yield and soil erosion were estimated and the priority of different soil erosion ...

This study was conducted to assess various environmental exposure measurements (total dust, ammonia and endotoxin) of poultry workers at the province of Isfahan, Iran. The results show that the workers who worked in enclosed systems of parent stock barns have the highest exposure to total and respirable dust: 21.3 +/- 3.2 and 4.6 +/- 0.9 mg/m3, respectively. In comparison with different ages of...

A new species of the lacertid genus Eremias Fitzinger, 1834 is described from northwest of Isfahan province, Central Iran. Two mitochondrial genes (cyt b and 12S DNA) were sequenced and analyzed as reliable molecular markers for the separation of this newly discovered species from closely related species within the genus Eremias: E. velox, E. persica, E. papenfussi, E. lalezharica, E. montana, ...
