Effects of 24-h pretreatment with AS or FS on viability of HUVECs exposed for 24 h to 32 % O2 (mild hyperoxic conditions) or to 21 % O2 (normoxic conditions), as evaluated by the trypan blue assay. Cells treated with FS and exposed to normoxic conditions were used as negative controls. Results are expressed as mean ± SD of three experiments. Data represent percentage of viable cells (mean percentage) calculated from the number of viable cells in treated samples versus negative control. *P < 0.05 versus FS-treated cells exposed to normoxic conditions. °P < 0.05 versus FS-treated cells exposed to hyperoxic conditions. AS, human serum obtained after Medox® capsules consumption; FS, human serum obtained immediately before Medox® capsules consumption
