The article titled "Retraction Note: Astaxanthin ameliorates cardiomyocyte apoptosis after coronary microembolization by inhibiting oxidative stress via Nrf2/HO-1 pathway in rats" has been retracted by the Editor-in-Chief of Naunyn-Schmiedeberg's Archives of Pharmacology. The retraction was made at the request of the corresponding author due to concerns about the high similarity of some images with previously published articles.
