Retraction statement: Advances in the physiological and pathological implications of cholesterol

The above article, published online on 28 February 2013 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor in Chief, William Foster, and John Wiley and Sons Ltd. The retraction has been agreed due to the publication of a similar paper by the same authors (with the exclusion of P Mardones) in Frontiers in Bioscience in January 2014. The authors believed that they had taken the necessary steps to withdraw their paper from Frontiers in Bioscience before they submitted to Biological Reviews in June 2012.
