Iran and blogging. Most of us, when encountering the relationship between the two, would probably think about conservatism and the extent of repression in the Islamic Republic of Iran. Arrests of some prominent Iranian bloggers, such as Hussein Derakshan, popularised through the Western media would also spring to mind. But not many of us would know that Persian is one of the most used languages...

Together, the world’s eight acknowledged nuclear powers—the United States (US), Russia, United Kingdom (UK), France, China, India, Pakistan, and the Democratic People’s Republic of Korea (North Korea)—have amassed an arsenal of almost 30,000 nuclear weapons since 1945. In addition, Israel is believed to be a nuclear power while Iran (and possibly Syria as well) is also suspected of developing n...

Cystic echinococcosis (CE) is a globally distributed parasitic infection of humans and livestock. The disease is of significant medical and economic importance in many developing countries, including Iran. However, the socioeconomic impact of the disease, in most endemic countries, is not fully understood. The purpose of the present study was to determine the monetary burden of CE in Iran. Epid...

353 Dear Editor, I read with interest the study by Alizadeh et al on the incidence and risk factors for retinopathy of prematurity (ROP) in northern Iran.[1] It is obvious that ROP, one of the most common causes of preventable blindness in preterm neonates, is emerging as a “third epidemic” in middle‐income countries, including Iran. This is due to the increasing survival of preterm neonates, i...

We present a general setup for junctions of semi-infinite 4-branes in AdS6 with the Gauss-Bonnet term. The 3-brane tension at the junction of 4-branes can be nonzero. Using the brane junctions as the origin of the ZN discrete rotation symmetry, we identify 3-brane tensions at three fixed points of the orbifold T /Z3 in terms of the 4-brane tensions. As a result, the three 3-brane tensions can b...

We read with great interest the article recently published in your journal about central venous cannulation of the internal jugular vein using ultrasound (US)-guided and anatomical landmark (AL) techniques in Iran (1). In their study, Fathi et al. concluded that the AL technique is superior to the US-guided method in Iran. As you are aware, the physician’s skill is the most important confounder...
