Magnetic resonance spectroscopy and ambulatory cardiovascular monitoring noninvasively gauge timing of phosphate metabolism and circulation

Chronobiologia. 1989 Jan-Mar;16(1):1-8.

Abstract

Circadian changes in high-energy phosphate metabolism of the human forearm and the relative independence of these metabolic changes from the circulation were noninvasively demonstrated and quantified by combining nuclear magnetic resonance spectroscopy (MRS), ambulatory blood pressure and heart rate monitoring and chronobiologic time series analysis.
