Bigger is smarter
When it comes to estimating the intelligence of various animal species, it may be as simple measuring overall brain size. In fact, making corrections for a species' body size may be a mistake. The findings were reported by researchers at Grand Valley State University and the Anthropological Institute and Museum at the University of Zürich, Switzerland. The study has now been published online in the journal Brain, Behavior, and Evolution.
New treatment offers relief from chronic back pain
Chronic back pain is a condition that affects a significant part of the population, with patients falling into three major groups; those with herniated discs, spinal stenosis (a nerve affecting narrowing of the spinal cord), and complications from failed back surgery. Radiofrequency thermolesioning is a widespread treatment for chronic back pain, but because of its neurodestructive nature, it is often considered an unsuitable treatment. more
Lipoic acid explored as anti-aging compound
Researchers said today they have identified the mechanism of action of lipoic acid, a remarkable compound that in animal experiments appears to slow down the process of aging, improve blood flow, enhance immune function and perform many other functions. more
Combining NSAIDs with chemotherapy, radiation may improve cancer treatment
Until recently, nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin and celecoxib (sold as Celebrex), were being hailed as promising cancer prevention drugs. However, the latest studies have concluded that in most cases the adverse side effect of these drugs -- including risk of cardiovascular and kidney disease -- outweigh the potential benefit. more
Long-term anti-clotting therapy sweetens stenting outcomes in diabetic patients
A study showing that diabetic patients who are treated with long-term anti-clotting therapy are less likely to have a heart attack or die more than a year after stenting has been named among the best research papers presented at the 30th Annual Scientific Sessions of the Society for Cardiovascular Angiography and Interventions (SCAI), May 9–12, 2007.
No magic tomato? Study breaks link between lycopene and prostate cancer prevention
Tomatoes might be nutritious and tasty, but don’t count on them to prevent prostate cancer. In the May issue of Cancer Epidemiology, Biomarkers & Prevention, researchers based at the National Cancer Institute and Fred Hutchinson Cancer Research Center report that lycopene, an antioxidant predominately found in tomatoes, does not effectively prevent prostate cancer. In fact, the researchers noted an association between beta-carotene, an antioxidant related to lycopene, and an increased risk for aggressive prostate cancer. more
Violent sleep disorder linked to a form of dementia
Mayo Clinic researchers and a group of international collaborators have discovered a correlation between an extreme form of sleep disorder and eventual onset of parkinsonism or dementia. more
