An international research team used the ultrabright X-rays of the Advanced Photon Source to examine neurons in the brains of schizophrenia patients. What they learned may help neurologists treat this harmful brain disorder. Schizophrenia, a chronic, neurological brain disorder, affects millions of people around the world. It causes a fracture […]

As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked to stem cell aging – and how the production of neurons can be reactivated. […]

NineSigma, representing a global 500 medical device company, invites proposals for technologies that can alleviate the deleterious effects of calcified coronary arteries in a manner that is both easier and safer than traditional angioplasty or atherectomy procedures. The goal of this RFP is to identify technologies, beyond those that are traditionally […]

Insomnia — trouble falling asleep, staying asleep or waking up too early — is a common condition in older adults. Sleeplessness can be exacerbated by osteoarthritis, the most common form of arthritis causing joint pain. While there are effective therapies for treating insomnia in older adults, many people cannot get […]

The blood-brain barrier prevents immune cells from circulating freely in the brain, and the breakdown of its function is a major cause of post-stroke inflammation. Now, for the first time, researchers have identified how a toxic stroke byproduct, acrolein, could activate the barrier-degrading enzyme proheparanase (proHPSE). The research group has […]

New research led by Swansea University in collaboration with researchers at the University of Bristol and the Francis Crick Institute in London has indicated that consuming a diet high in sugar fructose might prevent the proper functioning of peoples' immune systems in ways that have, until now, largely been unknown.
