The U.S. Food Safety and Inspection Service said a Seminole, Okla., firm is recalling more than 2 million pounds of cooked ham because of a labeling error. Sigma Processed Meats Inc. said the fully cooked ham products contain monosodium glutamate that is not declared on the ingredients label. MSG is used as a flavor enhancer, but some people have experienced adverse reactions after consuming the chemical. The recalled 12-pound bags of FUD-brand cooked ham bear a Use By date of May 23-Sept. 7,...

 Researchers have been seeking a safe and effective way to treat cognitive impairments associated with schizophrenia by enhancing N-methyl-D-aspartate (NMDA) glutamate receptors. Functional deficits in NMDA receptors may contribute to the underlying neurobiology of this disorder. The first generation of studies trying to stimulate NMDA receptors administered large amounts of substances, like glycine or D-serine, which indirectly enhance NMDA receptor function. While there were some...

 A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate.The discovery is important, in part, because deficits of the signaling protein in question, called oligophrenin-1 (OPHN1), have been previously linked with X-linked mental retardation. Indeed, problems at the...

Canadian researchers say they've discovered cells that support neuron survival also play a role in the death of neurons located in the eye. Researchers from the University of Montreal and McGill University said their findings might lead to improved therapies for some neurological disorders, including glaucoma and retinal artery occlusion. The scientists said in many neurodegenerative diseases, a main factor that kills neurons is excessive levels of the neurotransmitter glutamate. Diseases...

Researchers at the Universit© de Montreal (UdeM) and the Montreal Neurological Institute (MNI), McGill University have discovered that cells which normally support nerve cell (neuron) survival also play an active and major role in the death of neurons in the eye. The findings, published this week in The Journal of Neuroscience, may lead to more streamlined therapies for a variety of acute and chronic neurological disorders, including glaucoma and retinal artery occlusion.In many...

U.S. scientists say they've discovered individual nerve cells in the front part of the brain can hold memories for about one minute. Researchers from UT Southwestern Medical Center said their study of mice is the first to identify the specific signal that establishes non-permanent cellular memory and reveals how the brain holds temporary information. Assistant Professor Don Cooper, senior author, said the research has implications for addiction, attention disorders and stress-related memory...

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),...
