Using process analysis to assess the impact of medical education on the delivery of pain services: a natural experiment.

abstract：BACKGROUND:Enflurane and isoflurane are structural isomers with different anesthetic potencies and side effects. It is not clear whether these differences are produced by differing occupancy of common protein binding sites or by occupancy of different sites, but the very similar molecular properties make the latter pos...
