The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding potential reuse of the data reported in the article. Specifically:
The article appears to include a subset of data from  without an appropriate citation.
The control group data and results appear to be highly similar to those published in the authors' other articles [2,3,4].
The authors have been contacted to address these concerns. The corresponding author stated that the data are unique to each article. However, based on the extent of data similarities among these articles, the Editor-in-Chief no longer has confidence in the presented data.
J. C. Alves and C. Lavrador do not agree to this retraction. A. Santos, P. Jorge and L. Miguel Carreira have not responded to any correspondence from the editor or publisher about this retraction.
