The growth of cancerous tumors is fueled, at least in part, by the buildup of free radicals—highly reactive oxygen-containing molecules.

Data published in the June issue of the Journal of Alzheimer's Disease demonstrated that minimally-invasive biospectroscopy was able to identify changes in oxidative stress (OS) levels in blood plasma, which may prove to be a useful biomarker in the early detection of Alzheimer's disease. There is currently no accepted laboratory test for diagnosing Alzheimer's disease.

A team of scientists at Emory University School of Medicine has identified a direct link between oxidative stress and inflammatory signals in the blood.

Antioxidant supplementation was found to be effective in relieving pain and reducing levels of oxidative stress in patients with chronic pancreatitis (CP), reports a new study in Gastroenterology.

Although its been over a decade since endothelial progenitor cells or EPCs, cells that circulate in the blood repairing and replacing the cells that line blood vessels, were identified, the field is still evolving.

Dr. Marcus Conrad of the Institute of Clinical Molecular Biology and Tumor Genetics at the Helmholtz Zentrum München has decrypted the molecular mechanism through which the death of cells is caused by oxidative stress.

Oxidative stress describes the state level of oxidative damage in a cell, tissue or organ, caused by reactive oxygen species. Alcohol induces oxidative stress in the liver resulting in an imbalance between oxidants and anti-oxidants.

Oxygen, although essential for human life, can turn into an aggressive chemical that is outright toxic to important molecules inside our cells. This "oxidative stress" is associated with many diseases, such as Alzheimer's, heart disease and cancer, and has been suggested to be the culprit underlying aging.

Oxidative stress is known to underlie many human diseases including atherosclerosis, Parkinson's disease and Alzheimer's disease. A team of scientists from Boston College has found a means to discover more about what role oxidative stress plays in the development of diseases by studying it at the sub-cellular level.

Scientists have discovered new information about an immune pathway in mice that explains how oxidative stress that results from acute estrogen deficiency leads to the loss of bone. The finding, published in the Proceedings of the National Academy of Sciences, could help in identifying a new drug target for preventing postmenopausal bone loss.

The reported failure of vitamin E to prevent heart attacks may be due to underdosing, according to a new study by investigators at Vanderbilt University Medical Center.

Researchers in Taiwan have demonstrated for the first time that urban air pollution simultaneously affects key indicators of cardiovascular risk in young adults: inflammation, oxidative stress, coagulation and autonomic dysfunction.
