Thoughts on the impact of better technology on free radical theory: “The role of oxidative stress in aging proposed by the free radical theory has been the focus of investigations for more than fifty years. The results of a large number of these investigations provide support for this theory. However, numerous recent findings point to the existence of unexpected complexity in the relationships between oxidative stress and aging. This complexity is highlighted by the discovery [that] a key element of oxidative stress defenses in the model organism budding yeast, shortens lifespan in concert with enhanced resistance to oxidative stress. In addition to the implications of this finding for understanding aging, identification of this mutation by massively parallel sequencing of whole genomes emphasizes the enormous utility of next-generation sequencing technologies as investigative tools that will likely revolutionize genetics. … In some cases, the apparent disconnect between experimental results and predictions of the free radical theory regarding connections between oxidative stress and lifespan is related to hormesis effects that elevate oxidative and other stress defenses in response to low levels of oxidative stress. … The more transparently clear lesson here is that not all forms of oxidative stress are equivalent in their effects on aging. This isn’t surprising in the context of the multitude of pathways that respond to different forms of oxidative stress and the numerous mechanisms by which oxidants can modify different macromolecular targets. Whatever the explanation, [research findings] emphasize the enormous complexity of relationships between oxidative stress and aging.”

From the New York Times: “In the 100 years since the first moose swam into Lake Superior and set up shop on an island, they have mostly minded their moosely business, munching balsam fir and trying to evade hungry gray wolves. But now the moose of Isle Royale have something to say – well, their bones do. Many of the moose, it turns out, have arthritis. And scientists believe their condition’s origin can help explain human osteoarthritis – by far the most common type of arthritis, affecting one of every seven adults 25 and older and becoming increasingly prevalent. The arthritic Bullwinkles got that way because of poor nutrition early in life, an extraordinary 50-year research project has discovered. That could mean, scientists say, that some people’s arthritis can be linked in part to nutritional deficits, in the womb and possibly throughout childhood. The moose conclusion bolsters a small but growing body of research connecting early development to chronic conditions like osteoarthritis. … Nutrients, experts say, might influence composition or shape of bones, joints or cartilage. Nutrition might also affect hormones, the likelihood of later inflammation or oxidative stress, even how a genetic predisposition for arthritis is expressed or suppressed.”

Washington, Aug 17 : Non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision, found one of only two studies of its kind.
In one of only two studies of its kind, a study from researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts demonstrates that non-viral gene therapy can delay the onset of some forms of eye disease and preserve vision. The team developed nanoparticles to deliver therapeutic genes to the retina and found that treated mice temporarily retained more eyesight than controls. The study, published online in advance of print in Molecular Therapy, brings researchers closer to a non-viral gene therapy treatment for degenerative eye disorders… (Source: Health News from Medical News Today)
