AI‐Assisted Digital Single‐Molecule Activity Tracker for Decoupling Intrinsic Heterogeneity from Photo‐Oxidative Damage in High‐Photon‐Flux Enzymology

Advanced Science, EarlyView.
Employing a digital single‐molecule activity tracker (dSMAT), this research demonstrates that high‐photon‐flux irradiation drives progressive oxidative scarring in polymerases. Unlike simple thermal denaturation, real‐time kinetic tracking dynamically visualizes enzymes degrading into multiple impaired subpopulations.

Τhe Antioxidant Function of HDL in Atherosclerosis

Angiology, 2020
Atherosclerosis is a multistep process that progresses over a long period of time and displays a broad range of severity. In its final form, it manifests as a lesion of the intimal layer of the arterial wall.

Diverse functions of antioxidants

Free Radical Research, 2000
All biological organisms have developed a defense system against oxidative stress, which is comprised of many kinds of antioxidants. Antioxidants are classified by function into four categories; preventive antioxidants; radical scavenging antioxidants; repair and de novo antioxidants; and adaptation.

Antioxidant Functions of Ergothioneine

Reactive Oxygen Species, 2020
The function of ergothioneine (EGT) has been in controversy since the discovery of EGT in 1909. The present common understanding is that the functions of EGT remain unclear and that EGT does not seem to provide any advantage over other antioxidants. In this study, the ultraviolet-absorption spectra of EGT were measured at various pH.

Antioxidant functions of phytic acid

Free Radical Biology and Medicine, 1990
Phytic acid is a natural plant antioxidant constituting 1-5% of most cereals, nuts, legumes, oil seeds, pollen and spores. By virtue of forming a unique iron chelate it suppresses iron-catalyzed oxidative reactions and may serve a potent antioxidant function in the preservation of seeds. By the same mechanism dietary phytic acid may lower the incidence

Antioxidant functions of carotenoids

Free Radical Biology and Medicine, 1989
Carotenoid pigments, including hydrocarbons such as beta-carotene or xanthophylls such as lutein and zeaxanthin, are very widely distributed in nature, where they play an important role in protecting cells and organisms against the harmful effects of light, air, and sensitizer pigments.
