RSS

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

Vitamin D protects cells from stress that can lead to cancer

By inducing a specific gene to increase expression of a key enzyme, vitamin D protects healthy prostate cells from the damage and injuries that can lead to cancer, University of Rochester Medical Center researchers report.

Mitochondrial dysfunction and redox signaling in atrial tachyarrhythmia

Researchers at the University Hospital of Magdeburg (Germany) have discovered that atrial tachycardia is associated with mitochondrial dysfunction and oxidative stress followed by the activation of the NF-kB signalling pathway with induction of NF-kB target gene expression in atrial tissue.

Fat-cell hormone linked to kidney disease

Reduced levels of a hormone produced by fat cells and linked to the development of insulin resistance may also be related to a higher risk of kidney disease, according to a study led by researchers at the University of California, San Diego School of Medicine and Thomas Jefferson University.

Inhibiting stress oxidant may be new therapy for COPD

The study "Oxidative Stress is an Important Component of Airway Inflammation in Mice Exposed to Cigarette Smoke or Lipopolysaccharide" investigates the inflammatory responses in oxidative stress-deficient mice exposed to cigarette smoke.

Austrian scientists identify common mechanism underlying acute respiratory disease syndrome

The Spanish flu outbreak of 1918 killed between 30 and 50 million people. In the infected patients, the ultimate cause of death was acute respiratory distress syndrome (ARDS). This fatal condition is a massive reaction of the body during which the lung becomes severely damaged. ARDS can be induced by various bacterial and viral infections, but also by chemical agents.

Blood urate levels associated with the progression of Parkinson's disease

Higher blood levels of the compound urate, a salt derived from uric acid that is associated with gout, may be associated with a slower progression of Parkinson's disease, according to an article posted online today that will appear in the June 2008 print issue of Archives of Neurology.

Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection

As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease.

Rare genetic syndrome may hold key to cure for heat stroke

A genetic disorder that can cause a fatal rise in body temperature in some patients undergoing general anesthesia may hold the key to a cure for heat stroke, according to research published in the April 4 edition of the journal Cell.

Discovery of new effect for insulin

Researchers at the Joslin Diabetes Center have shown that insulin has a previously unknown effect that plays a role in aging and lifespan, a finding that could ultimately provide a mechanism for gene manipulations that could help people live longer and healthier lives.

HDL-associated protein gene linked to heart disease risk

The gene for the HDL-associated protein paraoxonase 1 (PON1) appears to be associated with coronary artery disease and with the risk of developing adverse cardiac events, and variations in both the PON1 gene and its related enzyme activity may increase the risk for cardiovascular disease events, according to a study in the March 19 issue of JAMA , a theme issue on Genetics and Genomics.
