BEVERLY HILLS, Calif., June 23 /PRNewswire-FirstCall/ -- OXIS INTERNATIONAL, INC. (OTC Bulletin Board: OXIS, Paris: OXI), announced today the appointment of Dr. Okezie Aruoma as President of its Scientific Advisory Board. Dr. Aruoma is considered to be the World's foremost leading researcher and authority on L-Ergothioneine (ERGO). Dr. Aruoma believes L-Ergothioneine to be the most profound and powerful antioxidant known to science with numerous use applications ranging from the treatment...

University of Montreal scientists discover free radical mechanism to viral invasion Canadian researchers have discovered a new way the body combats respiratory viral infections. In the prestigious journal PLoS Pathogens, scientists from the University of Montreal and the University of Montreal Hospital Research Center explain how the NOX2 molecule, an enzyme that generates a burst of highly reactive oxygen derivatives (or free radicals), activates defense genes and molecules when viruses...

Researchers at the Tulane University School of Medicine, in New Orleans, LA, have demonstrated that thymoquinone (TQ) a major component of black seed oil (Nigella sativa) can suppress the growth of several aggressive prostate cancer (PCa) cell lines, in vitro. Although previous studies have shown the anti-proliferative effects of TQ in different types of cancers, the molecular mechanism of this effect of TQ had not been delineated. Since TQ has a structure similar to ubiquinone, a component...

Anti-aging supplements made up of mixtures might be better than single compounds at preventing decline in physical function, according to researchers at the University of Florida's Institute on Aging. In addition, it appears that such so-called neutraceuticals should be taken before very old age for benefits such as improvement in physical function. The findings from rat studies, published last week in the journal PLoS One, have implications for how dietary supplementation can be used...

New research in the FASEB Journal shows free radicals damage mitochondria in our muscle cells, resulting in age-related muscle loss If you're an aging baby boomer hoping for a buffer physique, there's hope. A team of American scientists from Texas and Michigan have made a significant discovery about the cause of age-related muscle atrophy that could lead to new drugs to halt this natural process. This research, available online the FASEB Journal (http://www.fasebj.org), shows that free...

Memory and learning improved in mice with Alzheimer's disease that were crossbred with animals that produced large amounts of a potent antioxidant enzyme made in the mitochondria said researchers from Baylor College of Medicine and New York University in a report that appeared in the Proceedings of the National Academy of Sciences. "This is one of the first reports with so many improvements in cognition in these mice," said Dr. Robia Pautler, assistant professor in the departments of...

Age-related hearing loss is the most common sensory disorder among the elderly. But scientists are still trying to figure out what cellular processes govern or contribute to the loss. Now a University of Florida team and researchers from University of Wisconsin and three other institutions have identified a protein that is central to processes that cause oxidative damage to cells and lead to age-related hearing loss. The findings help point the way toward a new target for antioxidant...

Researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and Montana State University have discovered a fungal protein that plays a key role in causing disease in plants and animals and which also shields the pathogen from oxidative stress. The researchers have found that the fungal protein TmpL is critical for the infection of host tissue and helps these pathogens regulate oxidative stress responses that are caused by the presence of destructive reactive oxygen species, a...

If a circadian rhythm is like an orchestra - the united expression of the rhythms of millions of cells - a common chemical may serve as the conductor, or at least as the baton. The chemical is hydrogen peroxide (H2O2), the active ingredient in color safe bleach. Produced in all animal cells, hydrogen peroxide may act as a signal for the active and resting phases of living things, new research by USC biologists suggests. A study published in the journal PLoS ONE shows that hydrogen peroxide...

An international team of scientists, led by Monash University researchers, has found that anti-oxidants commonly touted for their health-promoting benefits, could contribute to the early onset of Type 2 diabetes. The team, led by Professor Tony Tiganis from the Monash Department of Biochemistry and Molecular Biology, has found that molecules known as Reactive Oxygen Species (ROS) may play a protective role in the early stages of Type 2 diabetes by enhancing insulin action. Anti-oxidants...
