    Evaluation of a biomarker of oxidative stress: the 8-iso prostaglandin F2α: prostaglandin F2α ratio in human plasma

    MILLER P.(1); NEWLAND K.(1); DZERK A.(1); FARMEN R.(1); TRAN C.T.(2); HAZIZA C.(2); PICAVET P.(2)
    (1) Celerion, Inc., Lincoln, NE, USA; (2) Philip Morris International, Neuchâtel, Switzerland
    F2-isoprostanes have been widely studied as biomarkers of oxidative stress for various indications, including smoking. Since both enzymatic biosynthesis and chemical lipid peroxidation can generate these biomarkers, there are various interpretations that ...
