Effect of H
in absence/presence of silicon (Si) G5. Results are expressed as means ± SEM of two experiments from different cultures, each one performed in quadruplicate with different batches of cells (total 8 measurements/condition). (*) = Statistical significances are referred to the basal values. (***) = p < 0.001. (●)/NS Statistical significances between H2O2 in absence and presence of silicon G5. NS = non significant, (●) = p < 0.05 and (●●) = p < 0.01.
