Effects of Prolonged Exposure to Hypobaric Hypoxia on Oxidative Stress: Overwintering in Antarctic Concordia Station

Figure 2

Acute and chronic hypobaric hypoxia-induced unbalance of oxidative stress and changes in nitric oxide metabolism: (a) thiobarbituric acid-reactive substances (TBARS) (μM); (b) protein carbonyls (PC) (nmol·mg^-1 protein); (c) 8-hydroxy-2-deoxyguanosine (8-OH-dG) (ng·mL^-1); (d) nitric oxide metabolites (NOx) (μM); (e) inducible nitric oxide synthase (iNOS) (I.U.), time course of concentration data. Data are shown as . Significant differences compared to T0 (baseline): ( symbol).
