Assessment of Antioxidant Capacity in vitro and in vivo
Free Radical Biology and Medicine, 2010The role and beneficial effects of antioxidants against various disorders and diseases induced by oxidative stress have received much attention. Many types of antioxidants with different functions play their role in the defense network in vivo. The free radical scavenging antioxidants are one of the important classes of antioxidants and the assessment ...

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.

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.

Determination of the antioxidant capacity in blood
Clinical Chemistry and Laboratory Medicine (CCLM), 2005AbstractBackground: A vast amount of scientific research is directed towards the beneficial effects of antioxidants on health. For this reason, several assays have been developed to determine the total antioxidant capacity of blood. Methods: In this study two procedures based on the use of the green-blue 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic ...

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.

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 ...

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.

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 ...
