Retraction: Collecting and measuring nociceptive and inflammatory mediators in surgical wounds.
The article Collecting and Measuring Nociceptive and Inflammatory Mediators in Surgical Wounds, has been retracted at the request of the authors due to duplication of text in J Pain (Carvalho B, Clark DJ, Angst MS (2008) Local and Systemic Release of Cytokines, Nerve Growth Factor, Prostaglandin E2, and Substance P in Incisional Wounds and Serum Following Cesarean Delivery. J Pain 9: 650-657.) due to an honest mistake of the authors.
