The two articles listed below have been retracted as a result of a notice received from the corresponding author, Akihiro Cho, that the studies described in the articles were undertaken without the approval of an institutional ethics committee. The Editor-in-Chief has therefore determined that the articles failed to meet the ethical standards required by the Journal.
