Scientific progress is an important indicator for the social and economic developments of any country. According to various reports, worldwide, Iran has the most growth in the field of science due to a high increase in the numbers of publications during the past decade. The aim of this study is to assess not only the quantity, but also the quality of publications of indexed Iranian journals and compare them to Turkey, as an Islamic neighboring country, in addition to the contributions of these two countries to our knowledge. A number of international journals with high impact factors were selected to assess the contributions of scientists from Iran and Turkey to the medical sciences. ⋯ Despite high numbers of published articles, both countries have medical journals with very low comparable citation rates and IF. Only one out of three Turkish articles is cited once by authors outside of Turkey and one of five Iranian articles is cited by authors outside Iran. The few high-cited articles address new therapies and interventional studies or diseases commonly encountered regionally, and are the results of the efforts of a few individuals in highly specialized fields. Turkish scientists are inclined to publish their scientific works more than Iranians in distinguished international journals. These articles deal more with regional diseases that are not common in Western countries. Developing countries can only contribute to world science when they focus their efforts on teamwork in order to research ways to solve country-specific diseases and their own health problems.

An overlapping distribution of α2-adrenergic receptors with cannabinoid receptors has been reported in certain brain structures such as the dorsal hippocampus. Thus, functional interactions between cannabinoid and α2-adrenergic systems in cognitive control seem possible. In the present study, we examine the possible role of α2-adrenergic receptors of the dorsal hippocampus on WIN55,212-2 state-dependent learning. ⋯ Modulation of α2-adrenergic receptors in the dorsal hippocampal CA1 regions can influence WIN55,212-2 induced amnesia and WIN55,212-2 state-dependent learning of an inhibitory avoidance task by pre- or post-synaptic mechanism(s).
