Reactive oxygen species in periodontitis
Recent epidemiological studies reveal that more than two-third of the world′s population suffers from one of the chronic forms of periodontal disease. The primary etiological agent of this inflammatory disease is a polymicrobial complex, predominantly ...

Mitochondrial Management of Reactive Oxygen Species [PDF]
Mitochondria in aerobic eukaryotic cells are both the site of energy production and the formation of harmful species, such as radicals and other reactive oxygen species, known as ROS.

Reactive oxygen species and redox compartmentalization
Reactive oxygen species (ROS) formation and signaling are of major importance and regulate a number of processes in physiological conditions. A disruption in redox status regulation, however, has been associated with numerous pathological conditions.

Reactive oxygen species in status epilepticus
It has long been recognized that status epilepticus can cause considerable neuronal damage, and this has become one of its defining features. The mechanisms underlying this damage are less clear.

Senescence, Stress, and Reactive Oxygen Species [PDF]
Generation of reactive oxygen species (ROS) is one of the earliest responses of plant cells to various biotic and abiotic stresses. ROS are capable of inducing cellular damage by oxidation of proteins, inactivation of enzymes, alterations in the gene ...

Reactive oxygen species and sperm cells [PDF]
There is a dynamic interplay between pro- and anti-oxidant substances in human ejaculate. Excessive reactive oxygen species (ROS) generation can overwhelm protective mechanism and initiate changes in lipid and/or protein layers of sperm plasma membranes.

Imaging Reactive Oxygen Species in Arthritis [PDF]
Reactive oxygen species (ROS) have been shown to play a role in the pathogenesis of arthritides. Luminol was used as the primary reporter of ROS and photons resulting from the chemiluminescence reaction were detected using a super-cooled CCD photon ...

Reactive oxygen species (ROS) is a collective term given to a group of oxygen-containing intermediates, many of which react with biomolecules such as DNA, lipids, or proteins. ROS include (but are not limited to) hydrogen peroxide (H2O2), the superoxide radical anion (O2˙−), the hydroxyl radical (˙OH), and singlet oxygen (1O2).

On the Clinical Pharmacology of Reactive Oxygen Species [PDF]
Reactive oxygen species (ROS) have been correlated with almost every human disease. Yet clinical exploitation of these hypotheses by pharmacological modulation of ROS has been scarce to nonexistent. Are ROS, thus, irrelevant for disease? No. One key misconception in the ROS field has been its consideration as a rather detrimental metabolic by-product ...

Mitochondria and reactive oxygen species [PDF]
Mitochondria are a quantitatively relevant source of reactive oxygen species (ROS) in the majority of cell types. Here we review the sources and metabolism of ROS in this organelle, including the conditions that regulate the production of these species, such as mild uncoupling, oxygen tension, respiratory inhibition, Ca2+ and K+ transport, and ...
