Abstract

The Editor-in-Chief has retracted this article. The article was found to contain significant overlap with another article under consideration at the same time, by one of the same authors [1]. Figure 8D appears to overlap with Fig. 3 of [2], and Fig. 3 of [3]. The authors are unable to provide a sufficient response to these concerns. The Editor has lost confidence in the data and conclusions of this article. Author Victor Sunday Aigbodion disagrees with this retraction. The remaining authors have not responded to correspondence from the publisher regarding this retraction.
