Snoring may destroy grey matter

A new Australian study has found that snoring and troubled nights could be a warning of brain damage occurring while sleeping. The team looked at brain scans of 60 people, aged in their mid-40s and recently diagnosed with a common sleep disorder – obstructive sleep apnea. Obstructive sleep apnea often affects overweight and the obese and leads to snoring. Results showed “decreased amount of grey matter” when compared to healthy sleepers.

Highlights of Frontiers in Optics 2010/Laser Science XXVI Meeting

Scientists and engineers from around the world will gather on the shores of Lake Ontario in Rochester, N.Y. next week to discuss some of the latest breakthroughs in lasers and optics and their applications to cutting-edge science, the development of new materials, and medicine.

Research on Reaper protein provides new treatment strategies for cancer

Our cells live ever on the verge of suicide, requiring the close attention of a team of molecules to prevent the cells from pulling the trigger. This self-destructive tendency can be a very good thing, as when dangerous precancerous cells are permitted to kill themselves, but it can also go horribly wrong, destroying brain cells that store memories, for instance. Rockefeller University scientists are parsing this perilous arrangement in ever finer detail in hopes that understanding the basic mechanisms of programmed cell death, or apoptosis, will enable them eventually to manipulate the process to kill the cells we want to kill and protect the ones we don't.

Scientists find potential Achilles Heel in JC polyomavirus

The JC polyomavirus doesn't strike very often, but it's a mean bug that preys on people with weakened immune systems, including people with AIDS, and almost always kills them. Now an international team of scientists at Brown University, the University of T-bingen in Germany, and Imperial College in London has found a potential Achilles Heel and painted a target on it: The virus must bind to a very specific sugar molecule dangling from the side of the brain cells it attacks.

UCSF professor receives National Medal of Science

UCSF Nobel laureate Stanley B. Prusiner, MD, UCSF professor of neurology and director of the Institute for Neurodegenerative Diseases, today (Oct. 15, 2010) was named to receive the National Medal of Science, the nation's highest honor for science and technology.

Major advance in treatment of brain disorders with external genes

In the October 17 issue of Nature Methods, researchers at Thomas Jefferson University describe how they can transfer genes into brain neurons intravenously, using a viral gene delivery vehicle (vector) that causes no side effects.

Researchers identify new paradigm for regulation of alternative splicing

How a T cell decides to make protein X, Y, or Z can have profound effects for fighting foreign invaders or staving off dire autoimmune reactions. Researchers at the University of Pennsylvania School of Medicine have identified the steps that control how different forms of an immune cell protein called CD45, which is critical for activating the immune system when faced with pathogens, are controlled in the arc of a body's immune response.

Pericytes regulate blood-brain barrier

While the blood-brain barrier (BBB) protects the brain from harmful chemicals occurring naturally in the blood, it also obstructs the transport of drugs to the brain. In an article in Nature scientists at the Swedish medical university Karolinska Institutet now present a potential solution to the problem. The key to the BBB is a cell-type in the blood vessel walls called pericytes, and the researchers hope that their findings will one day contribute to new therapies for diseases like Alzheimer's and stroke.

Study finds boosting mitochondria may delay onset of Parkinson's disease

In a study that sheds new light on the causes of Parkinson's disease, researchers report that brain cells in Parkinson's patients abandon their energy-producing machinery, the mitochondria. A shutdown in fuel can have devastating effects on brain cells, which consume roughly 20 percent of the body's energy despite making up only 2 percent of body weight.

Two-day symposium marks an extraordinary decade for Brown Institute for Brain Science

Just as intense concentration allows a sharp mind to perform at its peak, a research institute that concentrates pre-eminent scientists from 11 academic departments can push back the frontiers of knowledge in a complex research area: the human brain.

Parkinson’s disease pathology breakthrough

Researchers have found that brain cells of people with early Parkinson's disease have damaged powerhouses. In a new study they have identified 10 groups of gene sets related to the energy production problems in the brain cells of these people.

Researchers reveal ways to halt Rett Syndrome

In a study published today in the Journal, Proceedings of the National Academy of Sciences, an international team of researchers based in the U.S. and UK revealed that they were able to halt the potentially lethal, breath holding episodes associated with the neurological disease Rett syndrome.

Research on spatial memories may lead to potential treatments for addiction and obesity

A researcher from the Faculty of Medicine & Dentistry at the University of Alberta has discovered a mechanism underlying some forms of obesity and addictions which could lead to a treatment for both diseases.

Scientists discover c-Abl protein role in Parkinson's disease progression

Johns Hopkins scientists have discovered that the over-activation of a single protein may shut down the brain-protecting effects of a molecule and facilitate the most common form of Parkinson's disease.

NEUROKIN accentuates its leadership in the treatment of acute neurological diseases

Bbiotechnology company NEUROKIN, dedicated to the development of neuroprotective drugs to treat acute neurological diseases, announces today that the European Patent Office (EPO) has granted patent EP 1998778 protecting the use of NK-102, its most advanced drug candidate. This first European award constitutes an important milestone for NEUROKIN. An application for registration is under way in Brazil, Canada, China, USA and Japan.

People with Parkinson's disease have high levels of beta-HCH pesticide

People with Parkinson's disease have significantly higher blood levels of a particular pesticide than healthy people or those with Alzheimer's disease, researchers at UT Southwestern Medical Center have found.
