    Rapid and sensitive quantification of paraquat and diquat in human serum by liquid chromatography/time-of-flight mass spectrometry using atmospheric pressure photoionization

    We developed a rapid and sensitive liquid chromatography/time-of-flight mass spectrometry (LC/TOF–MS) method using atmospheric pressure photoionization (APPI) for the determination of paraquat and diquat in hu...

    Phosphatidylcholine hydroperoxide levels in human plasma are lower than previously reported

    The quantification of PC hydroperoxide (PCOOH) in human plasma was studied by HPLC with chemiluminescence detection (HPLC-CL). We identified for the first time the monohydroperoxide of 1-palmitoyl-2-linoleoyl-...

    Consecutive administration of paraquat to rats induces enhanced cholesterol peroxidation and lung injury

    It is our hypothesis that as a consequence of increased oxidative stress, rats develop lung injury with increased cholesterol-derived hydroperoxides and oxysterols in lung after consecutive exposure of the rat...
