Scientists at the University Medical Center in Mainz prove multiple DNA repair defect in monocytes Scientists working with Professor Bernd Kaina of the Institute of Toxicology at the Medical Center of Johannes Gutenberg University Mainz have demonstrated for the first time that certain cells circulating in human blood — so-called monocytes — are extremely sensitive to reactive oxygen species (ROS). They were also able to clarify the reason for this: ROS are aggressive forms of...

Scientists at the University of York have made a significant step forward in isolating the cause of Parkinson's disease in younger adults. Research by a team in the University´s Department of Biology found evidence that movement disorders, including tremor and slowness of movement (bradykinesia), associated with Parkinson´s disease (PD) may be due to a defect in energy production in the nervous system. The advance may help to identify young adults who may be susceptible to the...

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defenses. The aggressive oxygen compounds destroy...

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress. Now, a study by researchers in the University of Georgia College of Pharmacy has shown...

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open...

Swedish women who ate an antioxidant-rich diet had fewer strokes regardless of whether they had a previous history of cardiovascular disease, in a study reported in Stroke: Journal of the American Heart Association. "Eating antioxidant-rich foods may reduce your risk of stroke by inhibiting oxidative stress and inflammation," said Susanne Rautiainen, M.Sc., the study's first author and Ph.D. student at the Karolinska Institutet in Sweden. "This means people should eat more foods such as...

New findings suggest that activation of the PKM2 enzyme may sensitize cancer cells to oxidative stress It has long been known that cancer cells use nutrients differently than normal cells. In recent years, the rapidly reemerging field of cancer metabolism has shed new light on the ways that cancers use glucose to grow and thrive, demonstrating that manipulation of an enzyme called PKM2 is important to this metabolic process. Now a new study led by a scientific team at Beth Israel...

University of Illinois scientists report the first identification of a cellular mechanism linked to the toxicity of a major class of drinking water disinfection byproducts. This study, published in Environmental Science & Technology, suggests a possible connection to adverse health effects, including neurological diseases such as Alzheimer's. "I'm not implying that drinking disinfected water will give you Alzheimer's," said Michael Plewa, lead scientist and professor of genetics in the...

Expanding on this new study and in-line with another new study done by The Department of Internal Medicine, University of Miami, Florida, Nutri-Med Logic Corp says that an internal cellular pathway is becoming a primary focus of the attention for the treatment of diseases, ranging from Rheumatoid Arthritis to cancer. Miami, FL (PRWEB) October 21, 2011 Nutri-Med Logic Corp: A new study published in Arthritis & Rheumatism, an official monthly journal of the American College of...
