Erratum to: Tetrahydrobiopterin, L-Arginine and Vitamin C Act Synergistically to Decrease Oxidative Stress, Increase Nitric Oxide and Improve Blood Flow after Induction of Hindlimb Ischemia in the Rat

The April 2012 issue of Molecular Medicine contained a report from Yan et al.: Tetrahydrobiopterin, L-Arginine and Vitamin C Act Synergistically to Decrease Oxidative Stress, Increase Nitric Oxide and Improve Blood Flow after Induction of Hindlimb Ischemia in the Rat. Through an error in the final processing of the manuscript, the Journal published an interim version of the author’s work, not the final version approved by the reviewers and editorial board. Specifically, during the review of an earlier iteration of the manuscript, the reviewers had requested additional experiments, and the authors had performed those experiments and included them in a revised manuscript ultimately accepted by the editorial board. Unfortunately, these additional experiments, and the discussion of them, were not a portion of the article that was published in the April 2012 issue of the Journal.
