Drugs target Nox2 enzyme directly instead of acting as antioxidants 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). "Nox2 inhibitors could be valuable with many conditions where inflammation...

In Huntington's disease, abnormally long strands of glutamine in the huntingtin (Htt) protein, called polyglutamines, cause subtle changes in cellular functions that lead to neurodegeneration and death. Studies have shown that the activation of the heat shock response, a cellular reaction to stress, doesn't work properly in Huntington's disease. In their research to understand the effects of mutant Htt on the master regulator of the heat shock response, HSF1, researchers have discovered that...

A new study shows that the compound Coenzyme Q10 (CoQ) reduces oxidative damage, a key finding that hints at its potential to slow the progression of Huntington disease. The discovery, which appears in the inaugural issue of the Journal of Huntington's Disease, also points to a new biomarker that could be used to screen experimental treatments for this and other neurological disorders. "This study supports the hypothesis that CoQ exerts antioxidant effects in patients with Huntington's...

Lee Rannals for RedOrbit.com NASA has been in the field of space sciences for 53-years, but the space agency may be diving into the world of cosmetics unexpectedly. The U.S. space agency developed a fruit drink, known as AS10, to protect astronauts from radiation, but a new study shows astronauts are not the only humans who can benefit from the concoction. Researchers set out to test the affect AS10 may have on its 180 participants who do not frequently make trips outside the Earth's...

(Ivanhoe Newswire) -- A new study shows that oxidative stress may put obese patients at an increased risk of developing kidney damage after heart surgery. Oxidative stress generates harmful unstable reactive oxygen molecules. The study is appearing in the upcoming issue of the Journal of the American Society of Nephrology (JASN). More studies are needed to see if effective antioxidants can help reduce the risk. Acute kidney injury (AKI) affects 5% to 30% of heart surgery patients. AKI is...

Studies are needed to see if effective antioxidants can help reduce the risk Highlights: -Obese patients have an increased risk of developing kidney damage, or acute kidney injury, after heart surgery. -Oxidative stress associated with obesity seems to play a role in this increased risk. Acute kidney injury affects 5% to 30% of heart surgery patients. Oxidative stress may put obese patients at increased risk of developing kidney damage after heart surgery, according to a study...

Potential Dark Side To Diets High In Beta-Carotene

New research suggests that there could be health hazards associated with consuming excessive amounts of beta-carotene . This antioxidant is a naturally occurring pigment that gives color to foods such as carrots, sweet potatoes and certain greens. It also converts to vitamin A, and foods and supplements are the only sources for this essential nutrient. But scientists at Ohio State University have found that certain molecules that derive from beta-carotene have an opposite effect in the...

Government regulators and the scientific community should work to ensure that they give clear guidance to the public about dietary supplements and cancer risk, according to a commentary published April 25 in the Journal of the National Cancer Institute. Evidence from animal, in vitro and observational studies has suggested that taking dietary supplements may lower cancer risk. However, the small number of randomized controlled studies, the gold standard in evidence-based medicine, has not...

Reducing oxidative stress through exercise may eventually be used to treat sickle cell disease 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. Rather than all their red blood cells being affected,...

A newly published study, investigating the proper blood vessel formation (angiogenesis), implicates a specific factor (Nrf2) in premature aging of the blood vessels, as well as their improper healing. Expanding on this study Nutri-Med Logic Corp says that Nrf2, also known as a physiological regulator of oxidative stress, plays an important part in general premature aging as well as many diseases, ranging from Arthritis to Alzheimer. Miami, Florida (PRWEB) February 06, 2012 A new study,...
