Antioxidant capacity of the neurohormone melatonin
Journal of Neural Transmission, 2005The aim of this study was to elucidate the antioxidant behaviour of melatonin (M) and determine its activity-structure relationship. M or 5-metoxy-N acetyltriptamine is a neurohormone secreted by the pineal gland, which plays a proven role in maintaining sleep-wake rhythms.

Free Radicals and Antioxidants, 2016
Reactive oxygen species (ROS) are usually produced by the living cell and have different functions in its normal activity. However, if they are produced excessively, or if the system that keeps them in controlled levels is deficient or insufficient, a phenomenon known as oxidative stress is produced.

Antioxidant capacity in urban soils
Landscape and Urban Planning, 2014Abstract The quality of soils in 31 urban green areas in Pisa was assessed in terms their soil antioxidant systems by measuring antioxidant capacity (TEAC) and phenol substances, soil basal respiration, community level physiological profile (CLPP), expressed as average well color development (AWCD), community metabolic diversity (CMD), the Shannon ...

Beer is a polyphenol-rich beverage that has recently been reported to reduce the incidence of coronary heart disease and cancer. Some of the mechanisms by which this effect occurs have already been elucidated and include antioxidant, antiinflammatory, antimutagenic, antiangiogenic, estrogen-interfering, and cell cycle regulating actions of its phenolic

Total urine antioxidant capacity
Clinica Chimica Acta, 2001Total antioxidant capacity has been determined for several body fluids and provides a convenient means to compare antioxidant defenses among patients with acute or chronic inflammatory illnesses. We have studied urine specimens from a control group and a variety of patients with hypertension and acute and chronic renal diseases using an ABTS ...

Interaction between antioxidants in assays of total antioxidant capacity
Food and Chemical Toxicology, 2008Sub-additivity of antioxidant activities in assays of total antioxidant capacity has been reported previously and ascribed to binding of low-molecular weight antioxidants such as flavonoids by proteins. We demonstrate that this phenomenon is much more common and concerns also interactions between typical low-molecular weight oxidants in the assays of ...

Kinetic analysis of antioxidant capacity of wine
BioFactors, 1999AbstractA competition kinetics procedure for measuring total antioxidant capacity in wine is described. This procedure is based on the “crocin bleaching test” (Bors et al. Biochim. Biophys. Acta 1984, 796:, 312–319) as modified for analyzing the antioxidant capacity of complex mixtures (Tubaro et al. J. Am.

Evaluation of Antioxidant Capacity of Cereal Brans
Journal of Agricultural and Food Chemistry, 2004Several oat brans (crunchy oat bran, oat bran alone, and oat breakfast cereal) and wheat brans (wheat bran alone, wheat bran powder, wheat bran with malt flavor, bran breakfast cereal, tablet of bran, and tablet of bran with cellulose) used as dietary fiber supplements by consumers were evaluated as alternative antioxidant sources (i) in the normal ...

N-doped carbon as peroxidase-like nanozymes for total antioxidant capacity assay.
Analytical Chemistry, 2019N-doping strategy has been explored to enhance the activity of carbon nanozymes because the reconstructed electronic structures in N-doped carbon nanozymes are advantageous for the catalytic process.
