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

New Data Promises Alzheimer's Disease Early Detection

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.

Oxidized cysteine through diet reduces inflammation

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.

How oxidative stress impairs endothelial progenitor cell function

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.

Oxidative stress, Mechanism of cell death clarified

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.

Increased oxidative stress in decompensated cirrhotic patients

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.

Tool to probe role of oxidative stress in aging, disease

harminka — Fri, 15 Feb 2008 12:28:26 -0600

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.

Studying oxidative stress subcellular to discover its role in diseases

harminka — Sun, 16 Sep 2007 14:22:35 -0500

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.

Role of oxidative stress in estrogen-related bone loss

harminka — Tue, 11 Sep 2007 10:39:39 -0500

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.

Vitamin E's lack of heart benefit linked to dosage

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.

Air pollution linked to cardiovascular risk indices in healthy young adults

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.
