A new biosensor developed at Purdue University can measure whether neurons are performing correctly when communicating with each other, giving researchers a tool to test the effectiveness of new epilepsy or seizure treatments. Marshall Porterfield, an associate professor of agricultural and biological engineering and biomedical engineering, postdoctoral researcher Eric McLamore, and graduate student Subhashree Mohanty developed the self-referencing glutamate biosensor to measure real-time...

For the first time, research led by Youming Lu, PhD, MD, Professor of Neurology and Neuroscience at LSU Health Sciences Center New Orleans School of Medicine, has identified a novel mechanism that may trigger brain damage during stroke and identified a therapeutic approach to block it. The work, funded by the National Institute on Aging (NIA) and the National Institute of Neurological Disorders and Stroke (NINDS), both of the National Institutes of Health (NIH), as well as the American Heart...

Biomedical scientists from the University of Central Florida and Louisiana State University have identified a way to block a "cell death signal" that they believe triggers brain damage during strokes. Strokes, also known as cerebral ischemia, are caused by inadequate blood flow to the brain and are the third-leading cause of death in the United States. The team's work focused on a neurotransmitter that typically plays an important role in communication among nerve cells in the brain and...

Blocking the function of an enzyme in the brain with a specific kind of vitamin E can prevent nerve cells from dying after a stroke, new research suggests. In a study using mouse brain cells, scientists found that the tocotrienol form of vitamin E, an alternative to the popular drugstore supplement, stopped the enzyme from releasing fatty acids that eventually kill neurons. The Ohio State University researchers have been studying how this form of vitamin E protects the brain in animal and...

A drug already used to treat symptoms of epilepsy has potential to slow the muscle weakening that comes with amyotrophic lateral sclerosis (ALS), scientists report after completing a Phase II clinical trial"”an early, small-scale test to show if the drug works and continues to be safe. A report online December 4 in the journal Amyotrophic Lateral Sclerosis says the drug talampanel showed some ability to slow the loss of major daily life activities such as speaking, walking and dressing...

May set stage for treating brain damage in people Neurology researchers have shown that feeding amino acids to brain-injured animals restores their cognitive abilities and may set the stage for the first effective treatment for cognitive impairments suffered by people with traumatic brain injuries. "We have shown in an animal model that dietary intervention can restore a proper balance of neurochemicals in the injured part of the brain, and simultaneously improves cognitive performance," said...

The research group of Professor Magdalena Götz of Helmholtz Zentrum Mnchen and Ludwig-Maximilians-Universität (LMU) Munich has made a significant advance in understanding regeneration processes in the brain. The researchers discovered progenitor cells which can form new glutamatergic neurons following injury to the cerebral cortex. Particularly in Alzheimer's disease, nerve cell degeneration plays a crucial role. In the future, new therapeutic options may possibly be derived from...

UBC-Brain Research Centre discovery Scientists at the Brain Research Centre, a partnership of the University of British Columbia Faculty of Medicine and Vancouver Coastal Health Research Institute, have uncovered new information about the mechanism by which brain cells die following a stroke, as well as a possible way to mitigate that damage. The results of the study were recently published online in Nature Medicine. Following a stroke, many brain cells continue to die even after blood flow...

A domain of the NR2B subunit of the NMDA receptor is mapped in exquisite detail A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer's, Parkinson's, and other serious illnesses. Assistant Professor Hiro Furukawa, Ph.D., and colleagues at CSHL, in cooperation with the National Synchrotron Light Source at Brookhaven National Laboratory, obtained crystal...

Scientists discover lipid may be vital to learning Saturated fats have a deservedly bad reputation, but Johns Hopkins scientists have discovered that a sticky lipid occurring naturally at high levels in the brain may help us memorize grandma's recipe for cinnamon buns, as well as recall how, decades ago, she served them up steaming from the oven. The Hopkins team, reporting Oct. 29 in Neuron, reveals how palmitate, a fatty acid, marks certain brain proteins "“ NMDA receptors "“...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'
