Figure 4
Determination of the oxidative stress parameters 3-nitrotyrosine (3-NT) (a) and 8-Isoprostane (b) by commercial ELISA assays of a proof of increased reactive oxygen and nitrogen species formation in patients with leptin levels higher than the median. Data are . (c, d) Significant correlation of leptin and levels of the serum oxidative stress marker 3-NT in 40 patients ( values and correlation coefficients are provided in the graphs). Measured 3-NT staining was either normalized to Ponceau S staining (c) or transferrin content (d).
