Abstract
A method to assess oxidative stress in vivo includes the steps of measuring an amount of neuroprostanes in a biological sample before the ex vivo development of neuroprostanes in a sample, comparing the measured amount of neuroprostanes to a control and assessing oxidative stress in vivo based on this comparison. There is also provided a marker for oxidated stress by an increase of neuroprostanes in a biological sample compared to a control sample. A diagnostic tool for determining the presence of a neurodegenerative disease provides for determining an increased amount of neuroprostanes in a biological sample compared to that of a control sample.
Claims14
A method to assess oxidative stress in vivo comprising:
- (a) measuring the amount of neuroprostanes and metabolites thereof in a biological sample before the ex vivo development of neuroprostanes in the sample;
- (b) comparing the measured amount of the neuroprostanes and metabolites with a control;
- and
- (c) assessing oxidative stress in vivo based on the comparison in step b.
A marker for oxidative stress comprising neuroprostanes, isothromboxane-like compounds and isolevuglandin-like compounds derived from DHA, and metabolites thereof, which increase in a biological sample compared to a control sample during oxidative stress.
A diagnostic tool for determining the presence of a neurodegenerative disease comprising neuroprostane, isothromboxanes and metabolites thereof, which are increased in a biological sample compared to a control sample.
A metabolite of neuroprostanes isothromboxane-like compounds, and isolevuglandin-like compounds formed by one process from the group consisting essentially of beta oxidation, omega oxidation double bond reduction, dehydrogenation of the side chain hydroxyl groups, and reduction of the ring carbonyl to a hydroxyl group.
