Supplies and are constant with these obtained by Shi and colleagues [45] on a human liver cell line, in which OLE exerted a protective action from H2 O2 -induced oxidative three.1. Materials damage in concentrations ranging from 0.004 to 0.0160 mg/mL. The supplies made use of within this study were oleuropein (OLE; Sigma-Aldrich, St. Louis, Oxidative stress-induced damages on the corneal surface have been investigated, and MO, USA); hydroxypropyl–cyclodextrin reduction in antioxidant enzymes in sufferers several clinical studies [46,47] highlighted a parenteral grade (HP–CD; Kleptose, Roquette Freres, Lestrem, France);was connected to inflammation of the cular surface and the with DES, the extent of which phosphatidylcholine (Pho; Lipoid S one hundred; Lipoid, GmbH, Ludwigshafen, Germany); cholesterolagain, it really is shown that the Louis, MO, USA);point of severity of dry eye symptoms.

Cell Culture three. Supplies and Approaches The rabbit corneal epithelial cell line (RCE n. Cholesteryl sulfate Cancer 95081046) was obtained in the Eu3.1. Materials ropean Collection of Authenticated Cell Cultures (ECACC, Salisbury, UK). The growth The components employed in this study have been oleuropein (OLE; Sigma-Aldrich, St. Louis, medium had the following composition: Dulbecco’s modified Eagle’s medium with MO, USA); hydroxypropyl–cyclodextrin parenteral grade (HP–CD; Kleptose, Roquette Ham’s nutrient mixture F12 (1:1) (DMEM/F12) with addition f L-glutamine (2 mM), Freres, Lestrem, France); phosphatidylcholine (Pho; Lipoid S 100; Lipoid, GmbH, penicillin (one hundred UI/mL), streptomycin (0.1 mg/mL), amphotericin B (0.25 g/mL), fetal Ludwigshafen, Germany); cholesterol (Chol; Sigma-Aldrich, St. Louis, MO, USA); Krebsbovine serum heat-inactivated (15 v/v) (Gibco, Rodano, I), insulin (5 g/mL), and epiRinger buffer resolution (KRB, pH 7.4), variant without having NaCl, together with the following composition: dermal growth element (ten g/mL) (Sigma-Aldrich, St. Louis, MO, USA).
