Dr. Alfredo Quiñones-Hinojosa may not be able to cure his patients’ brain cancer, but there is one thing that the internationally renowned neurosurgeon and neuroscientist can provide them with: hope. (more…)
Mindfulness meditation training in awareness of present moment experience, such as body and breath sensations, prevents depression and reduces distress in chronic pain. In a new paper, Brown University scientists propose a neurophysiological framework to explain these clinical benefits. (more…)
In “before” and “after” photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless skin.
What we don’t appreciate is the vital role that our own natural biomolecules play in the healing process, including their contribution to the growth of new cells and the development of new blood vessels that provide nutrients to those cells. (more…)
Masonic Cancer Center researchers discover a virus-fighting enzyme
It’s well known that sunlight and chemical carcinogens can mutate DNA, and that mutations are essential for cancer to develop. (more…)
ANN ARBOR — Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.
Researchers at the University of Michigan Life Sciences Institute have identified a genetic program that promotes longevity of roundworms in cold environments—and this genetic program also exists in warm-blooded animals, including humans. (more…)
Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants – which are often used in spinal surgeries.
The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical complications and the need for additional surgeries. (more…)
In what could be an early step toward new treatments for people with osteoporosis, scientists at Michigan State University report that a natural probiotic supplement can help male mice produce healthier bones.
Interestingly, the same can’t be said for female mice, the researchers report in the Journal of Cellular Physiology.
“We know that inflammation in the gut can cause bone loss, though it’s unclear exactly why,” said lead author Laura McCabe, a professor in MSU’s departments of Physiology and Radiology. “The neat thing we found is that a probiotic can enhance bone density.” (more…)
The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics’ ability to fend off diseases – in animals and humans.
A study in the current issue of the Proceedings of the National Academy of Sciences shows that China – the world’s largest producer and consumer of antibiotics – and many other countries don’t monitor the powerful medicine’s usage or impact on the environment. (more…)
