The Editor-in-Chief has retracted this article because after publication concerns were raised regarding the validity of the conclusions drawn. Further review has revealed that the experimental procedure was not appropriate due to insufficient sample size, improper statistical methods and high probability of measurement errors, therefore, the explanation for the reduction in calcium and phosphorus content in Figure 4 is not justified by the data.

Noor Rahman and Rafiullah Khan do not agree to this retraction. Nabi Ahmed and Tanvir Hussain have not responded to any correspondence from the editor/publisher about this retraction.
