Biochemical characterization of human renal tumors by in vitro nuclear magnetic resonance

This study reports an in vitro magnetic resonance spectroscopy characterization of healthy renal parenchyma, renal cell carcinomas and oncocytomas. In vitro H-1 NMR measurements allow in-depth biochemical characterization of human healthy and neoplastic renal tissues. Some metabolites with an osmotic activity are considered markers of physiological renal function. Moreover, the HPLC technique was applied to investigate the amino acidic profile of these tissues: some amino acids appear to have statistic significance. (C) 2001 Elsevier Science B.V.
