Study Suggests Carbon Nanotubes May Protect DNA From Oxidation
2012-11-15 14:01:10

National Institute of Standards and Technology (NIST) Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation. In nature, oxidation is a common chemical process in which a reactive chemical removes electrons from DNA and may increase the chance for mutations in cells. More studies are needed to see if the in vitro protective effect of...

Promising Therapy For Huntington’s Disease Developed
2012-11-01 15:43:50

Lawrence Berkeley National Laboratory Initial results in mice could lead to new way to fight neurodegenerative diseases There´s new hope in the fight against Huntington´s disease. A group of researchers that includes scientists from the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice. The compound is a synthetic antioxidant that targets mitochondria, an...

The study of an oxygen-sensing bacterial regulatory protein by chemistry researchers at the University of Georgia has provided molecular insight into the oxygen sensing mechanism, which could ultimately lead to a better understanding of the ageing process and new treatments for human diseases such cancer, Parkinson's and Alzheimer's. Michael Johnson, a distinguished research professor of chemistry in the UGA Franklin College of Arts and Sciences, and Bo Zhang, a UGA chemistry doctoral...

Fruit Flies Enjoy Longer Life With Acai Berries
2012-08-22 14:42:11

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from Emory University recently discovered that acai has the ability to counteract oxidative stress and lengthen the lifespan of fruit flies. In the study, the scientists studied an acai berry product that could lengthen the lives of fruit flies. The health of the fruit flies was originally affected by oxidative stress, but certain conditions of a simple sugar diet and acai supplementation tripled the flies´...

A new and powerful class of antioxidants could one day be a potent treatment for Parkinson's disease, researchers report. A class of antioxidants called synthetic triterpenoids blocked development of Parkinson's in an animal model that develops the disease in a handful of days, said Dr. Bobby Thomas, neuroscientist at the Medical College of Georgia at Georgia Health Sciences University and corresponding author of the study in the journal Antioxidants & Redox Signaling. Thomas and...

Why do we age, and what makes some of us live longer than others? For decades, researchers have been trying to answer these questions by elucidating the molecular causes of aging. One of the most popular theories is that the accumulation of oxygen radicals over time might be the underlying culprit in aging. Oxygen radicals are chemically reactive molecules that can damage cellular components such as lipids, proteins and nucleic acids, resulting in "oxidative stress." The possible link...

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...
