Corrigendum to: Effects of Arthrocen, an avocado/soy unsaponifiables agent, on inflammatory mediators and gene expression in human chondrocytes

Within the Materials and Methods section of the paper by Goudarzi et al. 1, it was stated that Arthrocen is manufactured as per a patented process (U.S. patent EP2464248A2). However, this patent covers a general process for a ‘composition including an unsaponifiable fraction’ and does not relate to the manufacture of Arthrocen or the avocado and soya unsaponifiables it contains. Rather, Arthrocen possesses a US Trademark granted by the United States Patent and Trademark Office (USPTO 4397178).
