Quantitative analysis of urinary metabolites.
Relative abundances of metabolites obtained from 1H NMR spectra of urine samples collected from the db/db mice and the wildtype mice at 9-wk, 11-wk, 13-wk, 15-wk and 17-wk, respectively. Keys: MNA, 1-methylnicotinamide; *P < 0.05 and **P < 0.01 compared with age-matched wildtype mice; #P < 0.05 and ##P < 0.01 compared with the db/db mice at 9-wk.
