During the preparation of sodium 3,5-dibromo-4-nitrosobenzenesulphonate (DBNBS) of high purity for electron paramagnetic resonance (EPR) spin-trapping purposes, it was found that the material synthesised as part of the present study differed signific

Using the spin trap 3,5-dibromo-4-nitrosobenzene sulfonate (DBNBS), an oxidant was previously detected in the plasma of patients with renal failure and the synovial tissue of rheumatoid arthritis patients. This oxidant has been shown to react with DB

A simple but rapid capillary electrophoresis method was developed for the measurement of nitrite and nitrate in human extracellular fluids and other aqueous solutions. The capabilities of the method were demonstrated by the measurement of endogenous

DBNBS (3,5-dibromo-4-nitrosobenzenesulphonate) reacts with nitric oxide (NO) produced from nitrite ions in acid solution to give a radical with a characteristic electron spin resonance spectrum, attributable to a ‘DBNBS-NO’ product, and comprisin

Triplet—triplet extinction coefficients were evaluated by laser flash photolysis for the all-trans C40 carotenoids astaxanthin (I), β-carotene (II), canthaxanthin (III) and zeaxanthin (IV) in deaerated toluene at 298 K in the spectral region from

During laccase-catalyzed oxidation of beech wood fibers in an aqueous suspension, phenoxy radicals were detected in steady-state concentrations by electron-spin resonance (ESR) spectrometry of the suspension liquid, suggesting that colloidal lignin f

The colour of powder and reconstituted milk (Hunter's L-, a- and b-values), fluorescent oxidation products, and two peak areas (corresponding to β-lactoglobulin and α-lactalbumin) from size exclusion chromatography were measured 9 times during acce

The oxidative status of high-heat, medium-heat and low-heat whole milk powder was investigated at moderately accelerated storage conditions, with exposure to atmospheric air at 25 or 45 °C and at three water activities (0.11, 0.23 and 0.33 at 25 °C

Fifteen medium-heat whole milk powders manufactured at the same plant under identical processing conditions from 15 different batches of raw milk were subjected to accelerated storage at 50 °C and a water activity of 0.31 in air. With a view to the

The influence of eight commonly occurring carotenoids on (1) the production of spin adducts, (2) the hyperfine splitting constants aH and aN of the spin adduct electron spin resonance (ESR) spectra, and (3) the production of the oxidized N-tert-butyl
