Reduced phospholipid breakdown in Alzheimer's brains: a 31P spectroscopy study.

abstract：RATIONALE:Evidence suggesting that the endogenous cannabinoid (eCB) system can be manipulated to facilitate or impair extinction of learned behaviours has important consequences for opiate withdrawal and abstinence. We demonstrated that the fatty acid amide hydrolase (FAAH) inhibitor URB597, which increases eCB levels,...
