Rice University researchers have found a potential clue to the roots of epilepsy, autism, schizophrenia and other neurological disorders. While studying the peripheral nerves of the Drosophila, aka the fruit fly, Rice doctoral student Eric Howlett discovered an unanticipated connection between glutamate "“ an amino acid and neurotransmitter in much of the food we eat "“ and phosphoinositide 3-kinase (PI3K), an enzyme that, Howlett found, regulates the activity of neurons. Howlett...

People who use monosodium glutamate, or MSG, as a flavor enhancer in their food are more likely than people who don't use it to be overweight or obese even though they have the same amount of physical activity and total calorie intake, according to a University of North Carolina at Chapel Hill School of Public Health study published this month in the journal Obesity. Researchers at UNC and in China studied more than 750 Chinese men and women, aged between 40 and 59, in three rural villages in...

Using the same concept behind commercial breath-freshening strips, a Temple University researcher has developed a new, easier method for clinical taste testing.Greg Smutzer, director of the Laboratory of Gustatory Psychophysics in the Biology Department of Temple's College of Science and Technology, has created taste strips similar to breath-freshening strips, but these edible strips contain one of the five basic tastes that are detected by humans "” sweet, sour, salty, bitter and...

Using a rodent model of epilepsy, researchers found one of the body's own neurotransmitters released during seizures, glutamate, turns on a signaling pathway in the brain that increases production of a protein that could reduce medication entry into the brain. Researchers say this may explain why approximately 30 percent of patients with epilepsy do not respond to antiepileptic medications. The study, conducted by researchers at the National Institute of Environmental Health Sciences (NIEHS),...

Scientists using a new drug screening method in Drosophila (fruit flies), have identified several drugs and small molecules that reverse the features of fragile X syndrome -- a frequent form of mental retardation and one of the leading known causes of autism. The discovery sets the stage for developing new treatments for fragile X syndrome. The results of the research by lead scientist Stephen Warren, PhD, chair of the Department of Human Genetics at Emory University School of Medicine, are...

In the neural train wreck that is stroke, the cutoff of oxygen kills brain cells through a buildup of acid, as well as by overexciting receptors on the surface of brain cells. Now, researchers exploring the detailed mechanism of this excitotoxicity and acidotoxicity have discovered how an insidious chain of molecular events contributes to its damage. In an article in the November 23, 2005, issue of Neuron, Jun Gao and colleagues say that their findings could contribute to the development of...

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message? Research reported in the July 20 issue of the Journal of Neuroscience (released online July 13) by a team led by David Featherstone, a University of Illinois at Chicago assistant professor of biology, provides...

WINSTON-SALEM, N.C. "“ New research suggests novel treatment targets for the most common form of childhood epilepsy "“ with the potential to have fewer side effects than traditional therapy. The findings from Wake Forest University School of Medicine are reported today in the July issue of the Journal of Neurophysiology. Through studies in animals, the researchers learned more about the possible brain pathways involved in absence, or petit mal, seizures and tested a drug that...

  • Wasting away as a result of abstinence from food.
The word 'abrosia' comes from a Greek roots meaning 'not' and 'eating'.
