Infection and reactive oxygen species
Andrologia, 2009In previous years the physiologic and pathophysiologic significance of reactive oxygen species (ROS) on sperm function has been recognized. The impact of ROS during the invasion, adhesion and multiplication of microorganisms in the male genital tract are largely unknown.

Are Reactive Sulfur Species the New Reactive Oxygen Species?
Antioxidants & Redox Signaling, 2020Significance: Oxidative stress in moderation positively affects homeostasis through signaling, while in excess it is associated with adverse health outcomes. Both activities are generally attributed to reactive oxygen species (ROS); hydrogen peroxide as the signal, and cysteines on regulatory proteins as the target.

Oxygen, Reactive Oxygen Species and Tissue Damage
Current Pharmaceutical Design, 2004The diatomic molecule of oxygen contains two uncoupled electrons and can therefore undergo reduction, yielding several different oxygen metabolites, which are collectively called Reactive Oxygen Species or ROS. They are invariably produced in aerobic environments through a variety of mechanisms, which include electron "leakage" during biologic ...

Reactive oxygen species in mechanotransduction
American Journal of Physiology-Lung Cellular and Molecular Physiology, 2004a randomized clinical trial by the Acute Respiratory Distress Syndrome Network ([1][1]) demonstrated a 22% reduction in mortality in patients by reducing the tidal volume for mechanical ventilation from the conventional setting of 12 ml/kg to a lower setting of 6 ml/kg.

1994
It has been known for over a century that the combination of light, oxygen, and several dyes leads to the oxidation of organic substrates. Photooxygenation reactions are known to involve active forms of oxygen, formed as a direct consequence of the absorption of light.

Reactive oxygen species in cell signaling.
American Journal of Physiology - Lung cellular and Molecular Physiology, 2000Reactive oxygen species (ROS) are generated as by-products of cellular metabolism, primarily in the mitochondria. When cellular production of ROS overwhelms its antioxidant capacity, damage to cellular macromolecules such as lipids, protein, and DNA may ...

Reactive Oxygen Species as Mediators in Asthma
Pulmonary Pharmacology & Therapeutics, 2001This review describes production and effects of reactive oxygen species (ROS) on airway function. ROS are important in many physiological processes but can also have detrimental effects on airway cells and tissues when produced in high quantities or during the absence of sufficient amounts of anti-oxidants.

Reactive oxygen species in hypertension
Nature Reviews CardiologyHypertension is a leading risk factor for stroke, heart disease and chronic kidney disease. Multiple interacting factors and organ systems increase blood pressure and cause target-organ damage. Among the many molecular elements involved in the development of hypertension are reactive oxygen species (ROS), which influence cellular processes in systems ...

Oxidative Stress and Reactive Oxygen Species
2005This article discusses different aspects concerning classification/nomenclature, biochemical properties and pathophysiological roles of reactive oxygen species (ROS) which are pivotal to interpret the concept of oxidative stress. In vitro studies in both the prokaryotes and eukaryotes clearly demonstrate that exogenous or constitutive and inducible ...
