Thank to our international Reviewers 2013

We thank most sincerely the outstanding personalities listed below for their contribution as reviewers of submitted manuscripts in 2013. They joined the members of the Editorial Committee in selecting the best manuscripts for publication. Without their expertise, we would not have succeeded to increase the quality of the journal and its Impact Factor, which has reached 1.855 for 2012, with a five-year Impact Factor 1.924. The number of the manuscripts received worldwide in 2013 has been 800 and hopefully will increase in the next years, allowing further development of the journal.
