Dr. Remi Quirion (McGill University, Montreal, Quebec, Canada) described enhancement of the effects of pain-related peptides by PGE2 . This finding suggests a new, possible complimentary approach to the therapy of pain. Qurion also discussed anti-Alzheimer effect of polyphenols. This effect appears to be due not due to their antioxidant activity only. Quirion suggested the existence of membrane protein than binds polyphenols.
