The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding high similarity between images in Fig. 3 in this article and Fig. 3 in the authors' later study [1] representing different compounds or treatment groups. The authors have provided the original data to address these concerns. However, due to the high number of issues, the Editor-in-Chief therefore no longer has confidence in the presented data.


M. Afifi agrees to this retraction. None of the other authors have responded to any correspondence from the editor or publisher about this retraction.
