Astrocytes may contribute to Lou Gehrig's disease

Two papers by Columbia and Harvard researchers report for the first time that astrocytes (the most abundant non-neuronal cells in the central nervous system), which carry a mutated gene known to cause some cases of amyotrophic lateral sclerosis (ALS/Lou Gehrig's disease), induce motor neuron death.

Potential of nanotechnology in medicine

Scientists are working now to create novel nanostructures that serve as new kinds of drugs for treating cancer, Parkinson's and cardiovascular disease; to engineer nanomaterials for use as artificial tissues that would replace diseased kidneys and livers, and even repair nerve damage; and to integrate nanodevices with the nervous system to create implants that restore vision and hearing, and build new prosthetic limbs.

Associations between smoking, caffeine and NSAID use and Parkinson's disease

Individuals with Parkinson's disease are less likely to smoke or consume high doses of caffeine than their family members who do not have the disease, according to a report in the April issue of Archives of Neurology, one of the JAMA/Archives journals.

Smoking and drinking lots of coffee may protect against Parkinson's disease

In what must be a rare example of smoking supposedly providing some benefit, researchers in the U.S. say in families with a history of Parkinson's disease, those who smoke cigarettes and drink lots of coffee appear to reduce their risk of developing the disease.

Technology to make implantable devices safe for MRI

While magnetic resonance imaging (MRI) is already well established as a premiere non-invasive imaging technology, patients with implantable pacemakers, implantable cardiac devices, neurostimulators and other medical devices are often denied the evaluation their medical situation urgently requires.

Nicotine shown to enhance learning and memory

While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory, a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder.

How auxin regulates TIR1 in plants provides clues to new treatments for human diseases

For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone -- auxin -- interacts with its hormone receptor, called TIR1.

White matter tracts in brain play a significant role in the rapid control of behavior

As wise as the counsel to "finish what you've started" may be, it is also sometimes critically important to do just the opposite -- stop.

Stroke damage in a brain region known as the putamen is strongly linked to motor neglect

Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease.

New device sniffs out olfactory disorders that could be an early warning of Alzheimer's, Parkinson's

The Sniff Magnitude Test (SMT), an invention of UC Psychology Professor Robert Frank and Professor Emeritus Robert Gesteland of the UC Department of Cell Biology, is now under further development with the WR Medical Electronics Company in Stillwater, Minn. The company will manufacture and market the test.

Ropinirole reduces "off" time in Parkinson's

Parkinson disease patients taking the drug, ropinirole 24-hour prolonged release significantly reduced their daily "off" time in which Parkinson's symptoms like tremor, slowness, stiffness, and walking difficulty return as drugs wear off, according to a study published in the April 3, 2007, issue of Neurology, the scientific journal of the American Academy of Neurology.
