Oxidative stress is defined as “an imbalance between oxidants and antioxidants in favor of
the oxidants, leading to a disruption of redox signaling and control and/or molecular …

Abstract Since the Great Oxidation Event, about 2.4 billion years ago, the Earth is immersed
in an oxidizing atmosphere. Thus, it has been proposed that excess oxygen, originally a …

The first report demonstrating that prolonged endurance exercise promotes oxidative stress
in humans was published more than 4 decades ago. Since this discovery, many ensuing …

Among other mechanisms, oxidative stress has been postulated to play an important role in
the rate of ageing. Oxidative damage contributes to the hallmarks of ageing and essential …

Poultry in commercial settings are exposed to a range of stressors. A growing body of
information clearly indicates that excess ROS/RNS production and oxidative stress are …

A wide array of molecular pathways has been investigated during the past decade in order
to understand the mechanisms by which the practice of physical exercise promotes …

In the open metabolic system, redox-related signaling requires continuous monitoring and
fine-tuning of the steady-state redox set point. The ongoing oxidative metabolism is a …

Free radicals are chemical species (atoms, molecules, or ions) containing one or more
unpaired electrons in their external orbitals and generally display a remarkable reactivity …

Singlet oxygen (1O2) is a biologically relevant reactive oxygen species capable of efficiently
reacting with cellular constituents. The resulting oxidatively generated damage to nucleic …

Redox homeostasis is essential for the maintenance of diverse cellular processes. Cancer
cells have higher levels of reactive oxygen species (ROS) than normal cells as a result of …
