Molecular hydrogen has an anti-inflammatory and cardioprotective effect, which is associated with its antioxidant properties. Erythrocytes are subjected to oxidative stress in pathologies of the cardiovascular system, which is the cause of a violation of the gas transport function of blood and microcircul...
Figure 4. Comparison of MDA (A), hydrogen peroxide (H2O2), (B) superoxide (O2−) measured with a biosensor (C) and spectrophotometric method (D) between control and drought-stressed plants of Brassica species. The averaged fold change was presented as a comparison among species (D). Data...
