Expression of Concern: Studies on the Photon Interaction Parameters for Some Vitamins Using Monte Carlo Simulation

Abstract After the publication of this article, a concern was received about its peer review process. In the course of our investigation, we found that one of the peer reviewers may have compromised the review process. We notified the corresponding author, as the representative of all authors, that we were returning the paper to review. After new reviews were obtained, we sent them first to the corresponding author, and then to all authors, and requested the paper be updated in an erratum per the new review comments. We did not receive responses from the authors. We add this Expression of Concern to the paper because we do believe there are credible concerns about the reliability of the article. Depending on response by the authors, the status of this article may be updated. Citation of Original Article: S. M. Vahabi, M. S. Zafarghandi, and M.
