- Journal of Neuroscience paper describes role of Zinc in developing Alzheimer's - MELBOURNE, Australia, April 1 /PRNewswire-FirstCall/ -- Prana Biotechnology (ASX:PBT; Nasdaq: PRAN) today announced that an independent study conducted by researchers at the University of California, Irvine, validates Prana's fundamental drug strategy for Alzheimer's Disease in blocking the toxic interaction between Abeta and brain metals, such as zinc, that damages synapses and cause cognitive loss. The...

-A tiny genetic mutation is the key to understanding why nicotine--which binds to brain receptors with such addictive potency--is virtually powerless in muscle cells that are studded with the same type of receptor. That's according to California Institute of Technology (Caltech) researchers, who report their findings in the March 26 issue of the journal Nature.By all rights, nicotine ought to paralyze or even kill us, explains Dennis Dougherty, the George Grant Hoag Professor of Chemistry at...

New research provides strong support for the idea that one of the key functions of sleep is the consolidation of memories. The study, published by Cell Press in the February 12th issue of the journal Neuron, provides fascinating insight into the cellular mechanisms that govern the sleep-dependent consolidation of experiences that occur while we are awake.Although sleep is thought to facilitate memory and learning, the molecular links between sleep and synaptic plasticity are not well...

Discovery could lead to drugs targeting gene interactions By pinpointing two genes that cause autism-like symptoms in mice, researchers at MIT's Picower Institute for Learning and Memory have shown for the first time that multiple, interacting genetic risk factors may influence the severity of autistic symptoms. The study, reported in the Feb. 9 advance online edition of the Proceedings of the National Academy of Sciences (PNAS), lends support to researchers' long-suspected belief that in...

Findings Could Lead to More Personalized Alcohol Treatment Methods New research from the University of Virginia Health System could help explain why some alcoholics are more severe drinkers than others.   A UVA team has found strong evidence that the serotonin transporter gene, SLC6A4, plays a significant role in influencing drinking intensity among alcohol-dependent individuals. The study, published in the February 2009 issue of Alcoholism: Clinical & Experimental Research,...

Vanderbilt University Medical Center investigators have found a surprising link between brain iron levels and serotonin, a neurotransmitter involved in neuropsychiatric conditions ranging from autism to major depression. Appearing in the Proceedings of the National Academy of Sciences this week, the study by Randy Blakely, Ph.D., and colleagues also demonstrates the utility of a powerful in silico approach for discovering novel traits linked to subtle genetic variation. The serotonin...

DNA plays a role in the amount of alcohol you drink, researchers say. Among alcohol-dependent (AD) individuals, DNA variations in the brain's serotonergic system influence drinking intensity. Specifically the serotonin transporter gene (SLC6A4) contributes to a person's inclination to drink. Researchers analyzed the associations between 275 AD patients seeking treatment and six variations of SLC6A4. Of the six variations, those who carried two T alleles were found to drink more intensely than...

U.S. biophysicists say they have clarified the mysterious interaction between cholesterol and the brain's neurotransmitter receptors. University of Pennsylvania scientists said they have provided a new model of behavior for the nicotinic acetylcholine receptor, a well studied protein involved in inflammation, Alzheimer's disease, Parkinson's disease, schizophrenia, epilepsy, the effect of general anesthetics and addiction to alcohol, nicotine and cocaine. As a result of the study,...

Canadian researchers have found they can use positron emission tomography, or PET scans, to detect seasonal variations in brain chemical transport. Dr. Jeffrey Meyer of the Centre for Addiction and Mental Health in Toronto led a team of researchers who determined the variations in how much serotonin -- a brain chemical involved in regulating physical functions such as eating and energy balance -- is removed via serotonin transporter binding in the living brain can be correlated with the...

UCLA cellular neuroscientists are providing new insights into the mechanisms that underlie long-term memory "” research with the potential to treat long-term memory disorders. "The more we know about how long-term memory is induced in the brain and how our memories are maintained in the brain, the more we are going to be able to treat long-term memory loss," said David Glanzman, UCLA professor of physiological science and neurobiology, whose new research appears June 19 in the early...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
