These manuscripts were evaluated as part of the Task Force Friedhelm Hermann, a group that investigated the findings published from the lab of Friedhelm Hermann for the Deutsche Forschungsgemeinschaft. The independent committee reviewed concerns related to the validity of the data associated with the above papers.
As a result of the committee's findings, we are issuing a retraction of these papers. However, not all contributions by all authors of the papers were found to be fraudulent, and some authors have stated that their experimental contributions were legitimate.
