Abstract 'Reactive oxygen species'(ROS) is a generic term that defines a wide variety of
oxidant molecules with vastly different properties and biological functions that range from …

Oxidative stress is a component of many diseases, including atherosclerosis, chronic
obstructive pulmonary disease, Alzheimer disease and cancer. Although numerous small …

Sirtuins (SIRTs) are nicotine adenine dinucleotide (+)-dependent histone deacetylases
regulating critical signaling pathways in prokaryotes and eukaryotes, and are involved in …

Oxidative stress is closely related to the physiopathology of numerous diseases. Reactive
oxygen species (ROS), reactive nitrogen species (RNS), and reactive sulfur species (RSS) …

Reactive oxygen species (ROS) are metabolic byproducts that are necessary for
physiological function but can be toxic at high levels. Levels of these oxidative stressors …

Aging is characterized by systemic chronic inflammation, which is accompanied by cellular
senescence, immunosenescence, organ dysfunction, and age-related diseases. Given the …

Organisms are continually exposed to exogenous and endogenous sources of reactive
oxygen species (ROS) and other oxidants that have both beneficial and deleterious effects …

In plants, there is a complex and multilevel network of the antioxidative system (AOS)
operating to counteract harmful reactive species (RS), the foremost important of which are …

Nicotinamide adenine dinucleotide (NAD+) and its metabolites function as critical regulators
to maintain physiologic processes, enabling the plastic cells to adapt to environmental …

Contingent upon concentration, reactive oxygen species (ROS) influence cancer evolution
