Oxidative Modification of Biomolecules in the Nonstimulated and Stimulated Saliva of Patients with Morbid Obesity Treated with Bariatric Surgery

Figure 1

Oxidative damage to lipids (a, b), proteins (c, d), and DNA (e) in unstimulated and stimulated saliva of patients with morbid obesity at the baseline and 6 months after bariatric surgery as well as the healthy controls. C, control; O, morbid obese patients; ABS, patients after the bariatric surgery; NS, unstimulated whole saliva; S, stimulated whole saliva; 4-HNE protein adducts, 4-hydroxynonenal protein adducts; 8-isoP, 8-isoprostanes; AOPP, advanced oxidation protein products; PC, protein carbonyl groups, 8-OHdG, 8-hydroxyguanosine.
