The lungs are exposed to reactive oxygen species oxygen (ROS) produced as a result of
inhalation of oxygen, as well as smoke and other air pollutants. Cell metabolism and the …

Lung represents a tissue that encounters a high oxidant burden but is also endowed with
efficient protection against oxygen and reactive oxygen species (ROS). The oxidant stress …

Inflammatory lung diseases such as asthma and Chronic Obstructive Pulmonary Disease
(COPD) are characterised by systemic and local chronic inflammation and oxidative stress …

Reactive oxygen species are oxygen-based molecules readily reacting with various
compounds. It is already known that they play significant role in many physiological as well …

Regulation of reduction/oxidation (redox) state is critical for cell viability, activation,
proliferation and organ function, and imbalance of oxidant/antioxidant balance is implicated …

Oxidative stress is defined as an imbalance between the production of reactive oxygen
species (ROS) and the antioxidant capacity of the cell. For long, ROS have been considered …

Oxidative stress occurs when free radicals and other reactive species overwhelm the
availability of antioxidants. Reactive oxygen species (ROS), reactive nitrogen species, and …

Reactive oxygen species (ROS) such as superoxide anion (O2–) and the hydroxyl radical
(OH) are highly unstable species with unpaired electrons, capable of initiating oxidation …

Reactive oxygen species, either directly or via the formation of lipid peroxidation products,
may play a role in enhancing inflammation through the activation of stress kinases (c-Jun …

Induction of oxidant stress either by raising ambient oxygen concentrations, adding toxins
that augment intracellular oxidant formation, generating ischemia followed by tissue …
