Oxidative Stress News and Research

RSS

Oxidative Stress is a condition in which antioxidant levels are lower than normal. Antioxidant levels are usually measured in blood plasma.

Emory scientists identify new type of anti-inflammatory compound

Scientists at Emory University School of Medicine have identified a new type of anti-inflammatory compound that may be useful in treating a wide range of conditions, including neurodegenerative and autoimmune diseases. These compounds inhibit the enzyme Nox2, part of a family of enzymes responsible for producing reactive oxygen species (ROS).

NF-κB inhibitors can mitigate cellular damage and prevent aging-related degenerative changes

Age-associated degeneration is caused, at least in part, by accumulated cellular damage, including DNA damage, but how these types of damage drive aging remains unclear. Dr. Paul Robbins and colleagues at the University of Pittsburgh sought to address this question using a mouse model of DNA repair deficiency.

OSA independently linked with DPN in patients with type 2 diabetes mellitus

Obstructive sleep apnea (OSA) is independently associated with diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (T2DM), according to a new study from researchers in the UK. The severity of DPN is also correlated with the degree of OSA and the severity of nocturnal hypoxemia.

Gas NO plays a fundamental regulatory role in controlling bacterial function

Bacteria provide a well-known playground for scientists and the evolution of these earliest life forms has shed important perspective on potential therapies for some of the most common, deadly diseases. Researchers at Case Western Reserve University School of Medicine have now discovered that, the gas nitric oxide (NO), produced in all cells of the human body for natural purposes, plays a fundamental regulatory role in controlling bacterial function, via a signaling mechanism called S-nitrosylation (SNO), which binds NO to protein molecules.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.
