Biomolecules Responsible for the Total Antioxidant Capacity (TAC) of Human Plasma in Healthy and Cardiopathic Individuals: A Chemical Speciation Model [PDF]

Antioxidants, 2021
(1) Background: Much effort has been expended to investigate the antioxidant capacity of human plasma, attempting to clarify the roles of both metabolic and food substances in determining defenses against oxidative stress. The relationship between the total antioxidant capacity (TAC) and the concentrations of redox-active biomolecules in the human ...

Dysmetabolisms Can Affect Total Antioxidant Capacity (TAC) of Human Plasma: Determination of Reference Intervals of TAC by Way of CUPRAC-BCS Method [PDF]

Antioxidants, 2021
The total antioxidant capacity (TAC) of human plasma is an index of the redox buffer capacity of this biological fluid and could be a biomarker for those disorders affecting redox status. Distinguishing physiological from pathological conditions needs a reference.

A Non-Toxic Approach to Assess Total Antioxidant Capacity (TAC) of Exotic Tropical Fruits From Thailand [PDF]

Journal of Food Science and Technology, 2019
A simple flow injection analysis (FIA) integrating with a metal-free approach for total antioxidant capacity (TAC) was developed. The non-toxic reaction was based on generating a vibrant blue radical from imipramine to avoid the potential interferents arising from the colorful fruit extracts.

Do Leaf Total Antioxidant Capacities (TAC) Reflect Specific Antioxidant Potentials? – A Comparison of TAC and Reactive Oxygen Scavenging in Tobacco Leaf Extracts

Journal of Photochemistry and Photobiology B: Biology, 2010
Two traditional methods of total antioxidant capacity (TAC) assessment, Trolox equivalent antioxidant capacity (TEAC) and ferric reducing antioxidant power (FRAP) were applied to water extracts from tobacco leaves at various stages of senescence. Physiological status of the leaves was characterized by the effective photochemical quantum yield of ...

Total Antioxidant Capacity (TAC): Is It an Effective Method to Evaluate the Oxidative Stress in Uraemia?

Luminescence, 1998
Lipoprotein abnormalities are common in uraemia and are considered important factors for development of atherosclerosis and progression of renal disease. Reduction of total antioxidant capacity (TAC) and lipid peroxidation (LP) probably play a major role in both processes.

The Effect of Seasons on Total Antioxidant Capacity (TAC), Total Oxidant Capacity (TOC) and OSI (Oxidative Stress Index) Levels in Free-Living Blackbirds (Turdus merula) in Nature

Biology Bulletin, 2023
The oxidative stress level of organisms is one of the best indicators of whether they are healthy or not. The increase in oxidative stress level in the cell can affect the longevity of the organism as well as cause some immune diseases. In this study, wing, tail, tarsus lengths, weights, muscle and fat scores, Total Antioxidant Capacity (TAC), Total ...
