Total F2-isoprostanes levels in urine and plasma from diabetic patients. (A) Urine and (B) plasma samples from patients with nephropathy secondary to type 2 diabetes and age-matched controls were assayed for F2-isoprostanes by high-performance liquid chromatography as described in Materials and Methods. Data are expressed as mean ± standard error of mean of 3 independent analyses on 16–21 patients per group. **P < 0.01 vs controls; C, controls; DN, type 2 diabetic patients with nephropathy
