Electron transfer mechanisms lie at the heart of antioxidant action, governing how molecules intercept and neutralise reactive species. Primary pathways include hydrogen atom transfer, in which an ...

Oxidative stress arises when reactive oxygen species (ROS) overwhelm an organism’s native defence systems, leading to damage of lipids, proteins and nucleic acids. Probiotic microorganisms counteract ...

Vitamin C and other antioxidants stimulate the formation of new blood vessels in lung cancer tumors, a new study from Karolinska Institutet published in the Journal of Clinical Investigation shows.

Conceptual figure explaining the impact of HNBs on the antioxidant quality of tomatoes. (i) ONBs may use the free radicals produced by bubble rupture to induce the antioxidant mechanism, and (ii) HNBs ...

Vitamin C and other antioxidants stimulate the formation of new blood vessels in lung cancer tumors, a new study from Karolinska Institutet published in The Journal of Clinical Investigation shows.

"We've found that antioxidants activate a mechanism that causes cancer tumours to form new blood vessels, which is surprising, since it was previously thought that antioxidants have a protective ...

Oxidative stress, caused by an imbalance between reactive oxygen species (ROS) and antioxidant defenses, plays a central role in the development of non-communicable diseases (NCDs). These diseases, ...

While alternative health gurus often encourage increasing antioxidants in the diet and the taking of antioxidant nutritional supplements such as beta-carotene, vitamins A, C, and E, and selenium, new ...
