The authors have addressed an important issue in timely manner. The effect of cell phone radiation on human health is the matter of recent awareness and debate, as a result of the enormous increase in cell phone usage worldwide. Up to November 2011, there were about 6 billion subscriptions throughout the world.

the authors have addressed an important issue in an appropriate manner. The PSA test has been widely used to screen men for prostate cancer (Pca). It is important to mention that the PSA test is not panacea. Most men with increased serum PSA levels have benign prostatic hyperplasia, which is a normal part of aging.

Peer review plays a determining role in the eventual fate of submissions to international English-medium journals. In this study, a corpus of reviewers’ reports on 32 manuscripts in 3 different fields was solicited from a number of Iranian graduate students and a content analysis was performed to find the common organizational patterns and also the most frequent types of problems noted by the reviewers. The results revealed that review reports followed a certain format in terms of structural organization and negative/positive balance of the comments. Also, the results demonstrated that the most frequent type of problems noted by reviewers were contentrelated defects. However, because scientific information is conveyed through the language and content failure often overlaps language issues, language-use comments should be considered as important.
