Antioxidant Activity and Capacity Measurement
2021Measurement of antioxidant activity/capacity of foods and biological fluids is important for the determination of nutritional value of foods and for the diagnosis of diseases associated with oxidative stress. Antioxidant activity/capacity can be monitored using assays with different mechanisms, including (i) electron transfer-based assays, (ii ...

Plants cope several biotic and abiotic stresses during their germination and growth. Allelochemicals stress is most important and refers to the effects of secondary metabolites (produced by some plants) on growth of receptor plants. One of these effects is the oxidative stress, manifested as large production of free radicals.

The antioxidant capacity of saliva
Journal of Clinical Periodontology, 2002AbstractBackground/aims: Saliva, a heterogeneous fluid comprising proteins, glycoproteins, electrolytes, small organic molecules and compounds transported from the blood, constantly bathes the teeth and oral mucosa. It acts as a cleansing solution, an ion reservoir, a lubricant and a buffer.

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.

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 ...

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 ...

Cyclosporine reduces hepatic antioxidant capacity: protective roles of antioxidants
International Immunopharmacology, 2004The immunosuppressive agent cyclosporine A (CsA) has been reported to exert measurable hepatotoxic effects. One of the causes leading to hepatotoxicity is thought to be reactive oxygen radical formation. Therefore, this study was designed to elucidate possible relation between cyclosporine A treatment and antioxidant capacity (AOC) of hepatic tissue ...

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

Antioxidant capacity in severely burned patients
Pathologie Biologie, 2001Total antioxidant capacity (TAC) was measured after severe burns (non-electric with one exception) in two groups of patients: group A, 24 subjects (19 men and five women) 20-67 years old and group B, eight subjects (six men and two women) 20-54 years old, admitted to the Major Burns Unit of hospital general Vall d'Hebron over a period of nine months ...
