Urinary pteridines as a discriminator of atherosclerotic risk in patients with diabetes [PDF]
Atherosclerosis Plus, 2021 Background and aims: We have recently proposed urinary pteridine level as a useful biomarker of oxidative stress in a general population. However, the significance of urinary pteridines in patients with diabetes is unknown.
