Example text

F2-Isoprostane and its metabolites are found in urine and are stable and can be used as markers of oxidative stress. Three main assays are used for measuring F2-isoprostane in serum and urine: enzyme-linked immunosorbent assay (ELISA), gas chromatography combined with mass spectrometry, and liquid chromatography combined with mass spectrometry or tandem mass spectrometry. 5 Markers of Protein and DNA Damage spectrometry-based assays [36]. In addition, oxidation of γ-linoleic acid produces F1 series of isoprostanes and oxidation of eicosapentaenoic acid produces F3 series of isoprostanes, but these isoprostanes are not usually utilized as markers of lipid peroxidation.

3 Inhibition of Low-density Lipoprotein Oxidation, Linoleic Acid Oxidation, and Other Assays Based on Hydrogen Atom Transfer Reaction Inhibition of low-density lipoprotein (LDL) oxidation assay is also used to estimate total antioxidant capacity of extracts of natural products. Many antioxidants, including phenolic antioxidants present in red wine, inhibit LDL oxidation in vitro. Chu and Liu [9] measured free radical scavenging capacity of antioxidants and extracts of natural products by their ability to inhibit oxidation of human LDL by peroxyl radicals generated by thermal decomposition of water-soluble ABAP at 37 C.

However, other antioxidants can also be used for oxidation of ABTS, including manganese dioxide potassium persulfate and horseradish peroxidase. 0 mmol/L Trolox standard is calculated. 2 Measuring Total Antioxidant Capacity by Miller et al. [13], who also used this method to measure total antioxidant capacity of plasma collected from premature neonates and compared the values obtained with those in adult human plasma. Later, Erel [14] described an improved version of the assay in which ABTS was dissolved in water to achieve a concentration of 7 mmol/L and then radical cation ABTS 1 was produced by treating ABTS solution with potassium persulfate and allowing the mixture to stand in the dark at room temperature for 12À16 h to produce a dark blue solution.
