Natural vitamin E may reduce brain damage after stroke

Ten weeks of preventive supplementation with a natural form of vitamin E called tocotrienol in dogs that later had strokes reduced overall brain tissue damage, prevented loss of neural connections and helped sustain blood flow in the animals' brains, a new study shows.

Healthy diet might help reduce risk of macular degeneration

Eating a diet high in vitamin D, as well as the nutrients betaine and methionine, might help reduce the risk of macular degeneration, according to new research conducted by Tufts Medical Center scientists. Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration.

Tel Aviv University researcher finds link between back pain and genetics

A common complaint, back pain is one of the many side effects of aging. Over three quarters of the population experience it at some point, and until now, researchers have had little conclusive proof of the causes and mechanisms of the pain.

Potential new approach for treating obesity, type 2 diabetes

Scientists at the National Institutes of Health have uncovered a pathway in mice that allows white fat - a contributor to obesity and type 2 diabetes - to burn calories in a way that's normally found in brown fat and muscle. The findings are in the July 6 edition of Cell Metabolism.

Alpha-tocotrienol protects brain cells after stroke in three ways

A natural form of vitamin E called alpha-tocotrienol can trigger production of a protein in the brain that clears toxins from nerve cells, preventing those cells from dying after a stroke, new research shows.

Never smokers' lung adenocarcinomas show greater genome instability

Lung adenocarcinomas in people who have never smoked show greater genome instability than those in smokers, supporting the theory that lung cancer in never smokers arises through different pathways, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer.

LCMC finds 9.6% of lung cancer patients with ALK rearrangement

ALK rearrangement has been found in 9.6% of lung cancer patients tested in the Lung Cancer Mutation Consortium, and MET amplification in another 4.1%, reflecting how many patients might benefit from targeted therapies such as crizotinib, according to research presented at the 14th World Conference on Lung Cancer in Amsterdam, hosted by the International Association for the Study of Lung Cancer.

Ways to protect children from X-ray radiation

The risk to children's health from X-ray radiation is easy to reduce without compromising diagnostic accuracy. Gerhard Alzen and Gabriele Benz-Bohm describe some ways to achieve this in the current edition of Deutsches Ärzteblatt International.

Johns Hopkins team reconstitutes single stem cells' family tree

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia - important types of brain cells - but also of taking a wholly unexpected path: generating two new brain stem cells.

U-M researchers a step closer to developing treatments for aging and chronic diseases

As our bodies first form, developing cells are a lot like children put on the school bus with their names and addresses pinned to their shirts. The notes identify one as a future heart cell, another as a liver cell, a third as a neuron. And that's what they each grow up to be. But once those cells reach adulthood, changes to those original marching orders caused by aging, disease and other stressors like smoking can precipitate a kind of identity crisis, researchers at the University of Michigan Health System have found.

STSI receives NIH grant to conduct heart-based research

Researchers looking to find a root cause for heart attacks and coronary artery disease will soon begin using a novel investigative approach that borders on science fiction as they work toward the holy grail of American medicine: preventing the nation's No. 1 killer.

'Genotype positive' individuals susceptible to increased periodontal tissue destruction after dental implants

The health of the surrounding tissue affects the success of a dental implant. Identifying and reducing risk factors is therefore a key step in the implant process. Now a combination of genes has been identified as a possible indicator of greater tissue destruction leading to negative outcomes for implants.
