Exercise Intensity and Antioxidant Ability

Rejuvenation Research, 2010
We performed maximal exercise tests on 6 men using a bicycle ergometer and then measured the ferric-reducing ability in plasma to clarify the relationship between antioxidant status and exercise intensity. The ferric-reducing ability showed a rectilinear increase with the increase in exercise intensity, whereas the generation of hydroxyl radicals ...

Antioxidant and photo-antioxidant abilities of catechins

Journal of Photochemistry and Photobiology A: Chemistry, 2008
Abstract Catechins are studied vigorously, in particular, concerning the antioxidant ability as polyphenol, which is generally considered responsible for photo-antioxidant natures of catechins. In this study, the antioxidant and photo-antioxidant abilities of (+)-catechin, (−)-epicatechin, and epigallocatechin have been investigated kinetically and ...

Chemical and cytological evaluation of honeybee pollen antioxidant ability

Journal of Food Science, 2020
Abstract The crude flavonoid extract of pollen (CFP) of four species of honeybee pollens were extracted with ethanol, and the total flavonoid contents ranged from 3.4 to 14.5 mg rutin/g dry weight. The antioxidant activities of the CFPs were evaluated from both chemical and cytological aspects.

Photo-antioxidant abilities of 2-hydroxybenzoyl compounds

Polymer Degradation and Stability, 2005
Plastics are indispensable for our comfortable life. But, they are easily degraded by autoxidation, especially under the action of UV light, due to their organic character. Therefore, additives preventing the photo-oxidation are needed. 2-Hydroxybenzophenones are widely used as ultraviolet absorbers (UVA), and their effect is discussed in many papers ...

Biomimetic Polyphenolic Scaffolds with Antioxidative Abilities for Improved Bone Regeneration

ACS Applied Bio Materials, 2023
Bone defects have a severe impact on the health and lives of patients due to their long-lasting and difficult-to-treat features. Recent studies have shown that there are complex microenvironments, including excessive production of reactive oxygen species. Herein, a surface functionalization strategy using metal-polyphenolic networks was used, which was

Antioxidative ability of 5'-ribonucleotides in dehydrated model systems.

Agricultural and Biological Chemistry, 1989
The antioxidative ability of inosine 5 -monophosphate (IMP) and guanosine 5′-monophosphate (GMP) at various water activities (Aw, 0~0.75) and at 40°C was investigated. IMP and GMP exhibited antioxidative ability above Aw 0.25, and this ability was strongest at Aw 0.5. There was no obvious difference between the ability of IMP and GMP.

A new nutrient polypeptide-Fe and its antioxidant ability

International Journal of Food Sciences and Nutrition, 2009
Polypeptide-Fe is the hemoglobin that is purified highly from animal blood. It is an active material obtained by connecting heme with a different-length peptide section after physical and chemical processing. Polypeptide-Fe is non-toxic to the human body, does not have the side effects, and namely has iron enhancement function.

Monitoring antioxidative ability in patients with traumatic shock

Clinical chemistry and laboratory medicine, 2003
Patients diagnosed with traumatic shock suffer from severe oxidative stress caused by disordered balance between free radicals and antioxidants. The aim of the study was to establish antioxidative ability (ImAnOx) in patients with traumatic shock, and to determine whether supplementation therapy with vitamins E and C lead to improved antioxidative ...
