(a) Comparison of the oxidative stress markers in the subgroups at particular steps of the study protocol. (b) Comparison of the prostanoids levels in the subgroups at particular steps of the study protocol. (c) Comparison of the endothelial activation markers in the subgroups at particular steps of the study protocol. GSH/GSSG: thiol index, the reduced to oxidized glutathione ratio, MDA: malondialdehyde (lipid peroxidation marker), TXB2: thromboxane B2, 6-keto-PGF-1 alpha: 6-keto-prostaglandin F-1 alpha (a metabolite of prostacyclin, PGI2), PAI-1: plasminogen activator inhibitor-1, sVCAM-1: soluble vascular cell adhesion molecule-1, sICAM-1: soluble intercellular adhesion molecule-1, and VEGF: vascular endothelial growth factor. ∗p < 0,05 versus control. #p < 0,05 versus the same group at baseline.
