The study was among the first of its type to specifically measure a wide range of blood nutrient levels instead of basing findings on less precise data such as food questionnaires, and found positive effects of high levels of vitamins B, C, D, E and the healthy oils most usually found in fish........ ]]> http://medicineworld.org/stories/lead/7-2011/fast-prediction-of-axon-behavior.html http://medicineworld.org/stories/lead/7-2011/fast-prediction-of-axon-behavior.html Thu, 29 Dec 2011 01:08:18 GMT Scientists at Case Western Reserve University have developed a computer modeling method to accurately predict how a peripheral nerve axon responds to electrical stimuli, slashing the complex work from an inhibitory weeks-long process to just a few seconds. The method, which enables efficient assessment of a nerve's response to millions of electrode designs, is an integral step toward building more accurate and capable electrodes to stimulate nerves and thereby enable people with paralysis or amputated limbs better control of movement........ ]]> http://medicineworld.org/stories/lead/6-2011/link-between-parkinsons-and-pesticides.html http://medicineworld.org/stories/lead/6-2011/link-between-parkinsons-and-pesticides.html Thu, 29 Dec 2011 01:08:18 GMT In a new article reported in the journal Molecular Neurodegeneration, scientists at the University of Missouri School of Medicine take some of the first steps toward unraveling the molecular dysfunction that occurs when proteins are exposed to environmental toxins. Their discovery helps further explain recent NIH findings that demonstrate the link between Parkinson's disease and two particular pesticides - rotenone and paraquat........ ]]> http://medicineworld.org/stories/lead/6-2011/stem-cell-model-offers-clues-to-cause-of-inherited-als.html http://medicineworld.org/stories/lead/6-2011/stem-cell-model-offers-clues-to-cause-of-inherited-als.html Thu, 29 Dec 2011 01:08:18 GMT An international team of researchers led by scientists at the University of California, San Diego School of Medicine have used induced pluripotent stem cells (iPSCs) derived from patients with amyotrophic lateral sclerosis (ALS) to reveal for the first time how reduced levels of a specific protein may play a central role in causing at least one inherited form of the disease........ ]]> http://medicineworld.org/stories/lead/6-2011/source-of-key-brain-function.html http://medicineworld.org/stories/lead/6-2011/source-of-key-brain-function.html Thu, 29 Dec 2011 01:08:18 GMT Researchers at the University of Southern California have pinned down the region of the brain responsible for a key survival trait: our ability to comprehend a scene�even one never previously encountered�in a fraction of a second. The key is to process the interacting objects that comprise a scene more quickly than unrelated objects, as per corresponding author Irving Biederman, professor of psychology and computer science in the USC Dornsife College and the Harold W. Dornsife Chair in Neuroscience........ ]]> http://medicineworld.org/stories/lead/5-2011/snapshots-of-huntingtons-disease-protein.html http://medicineworld.org/stories/lead/5-2011/snapshots-of-huntingtons-disease-protein.html Thu, 29 Dec 2011 01:08:18 GMT Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee have for the first time successfully characterized the earliest structural formation of the disease type of the protein that causes Huntington's disease. The incurable, hereditary neurological disorder is always fatal and affects one in 10,000 Americans........ ]]> http://medicineworld.org/stories/lead/5-2011/the-brain-performs-visual-search-near-optimally.html http://medicineworld.org/stories/lead/5-2011/the-brain-performs-visual-search-near-optimally.html Thu, 29 Dec 2011 01:08:18 GMT In the wild, mammals survive because they can see and evade predators lurking in the shadowy bushes. That ability translates to the human world. Transportation Security Administration screeners can pick out dangerous objects in an image of our messy and stuffed suitcases. We get out of the house every morning because we find our car keys on that cluttered shelf next to the door........ ]]> http://medicineworld.org/stories/lead/4-2011/parkinsons-disease-and-prostate-cancer.html http://medicineworld.org/stories/lead/4-2011/parkinsons-disease-and-prostate-cancer.html Thu, 29 Dec 2011 01:08:18 GMT University of Utah School of Medicine scientists have found compelling evidence that Parkinson's disease is linked to an increased risk of prostate cancer and melanoma, and that this increased cancer risk also extends to close and distant relatives of individuals with Parkinson's disease. Eventhough a link between Parkinson's disease and melanoma has been suspected before, this is the first time that an increased risk of prostate cancer has been reported in Parkinson's disease........ ]]> http://medicineworld.org/stories/lead/4-2011/nurturing-newborn-neurons.html http://medicineworld.org/stories/lead/4-2011/nurturing-newborn-neurons.html Thu, 29 Dec 2011 01:08:18 GMT Adult mice engineered to have more newborn neurons in their brain memory hub excelled at accurately discriminating between similar experiences � an ability that declines with normal aging and in some anxiety disorders. Boosting such neurogenesis in the adult hippocampus also produced antidepressant-like effects when combined with exercise, in the study funded by the National Institutes of Health........ ]]> http://medicineworld.org/stories/lead/4-2011/4-new-genes-identified-for-alzheimers.html http://medicineworld.org/stories/lead/4-2011/4-new-genes-identified-for-alzheimers.html Thu, 29 Dec 2011 01:08:18 GMT Mount Sinai School of Medicine scientists are part of a consortium that has identified four new genes that when present increase the risk of a person developing Alzheimer's disease during the later part of life. The findings are reported in the current issue of Nature Genetics. The consortium also contributed to the identification of a fifth gene reported by other groups of researchers from the United States and Europe........ ]]> http://medicineworld.org/stories/lead/3-2011/sleep-during-adolescence.html http://medicineworld.org/stories/lead/3-2011/sleep-during-adolescence.html Thu, 29 Dec 2011 01:08:18 GMT Eventhough adolescents need just as much sleep as younger children, sleep times decrease over the course of development, leaving a number of teens chronically sleep-deprived. Studies have consistently indicated that insufficient sleep can have a negative effect on a number of aspects of adolescents' lives, leading to mood disturbances, poorer physical health, and academic difficulties. But few studies have examined how sleep affects the ways adolescents function on a daily basis or how the effects of sleep change over time........ ]]> http://medicineworld.org/stories/lead/3-2011/migraine-headaches-and-a-common-heart-defect.html http://medicineworld.org/stories/lead/3-2011/migraine-headaches-and-a-common-heart-defect.html Thu, 29 Dec 2011 01:08:18 GMT Cincinnati, OH, March 31, 2011 -- Roughly 15% of children suffer from migraines, and approximately one-third of these affected children have migraines with aura, a collection of symptoms that can include weakness, blind spots, and even hallucinations. Eventhough the causes of migraines are unclear, a newly released study soon to be published in The Journal of Pediatrics suggests a correlation between migraine headaches in children and a heart defect called patent foramen ovale, which affects 25% of people in the U.S........ ]]> http://medicineworld.org/stories/lead/3-2011/activity-of-single-neurons-during-seizures.html http://medicineworld.org/stories/lead/3-2011/activity-of-single-neurons-during-seizures.html Thu, 29 Dec 2011 01:08:18 GMT Typically the first study to examine the activity of hundreds of individual human brain cells during seizures has observed that seizures begin with extremely diverse neuronal activity, contrary to the classic view that they are characterized by massively synchronized activity. The investigation by Massachusetts General Hospital (MGH) and Brown University scientists also observed pre-seizure changes in neuronal activity both in the cells where seizures originate and in nearby cells. The report will appear in Nature Neuroscience and is receiving advance online publication........ ]]> http://medicineworld.org/stories/lead/3-2011/psychiatric-symptoms-in-children-with-epilepsy.html http://medicineworld.org/stories/lead/3-2011/psychiatric-symptoms-in-children-with-epilepsy.html Thu, 29 Dec 2011 01:08:18 GMT A newly published report reveals that children with epilepsy are more likely to have psychiatric symptoms, with gender a determining factor in their development. Findings showed that girls had more emotional problems, while boys had more hyperactivity/inattention problems and issues regarding peer relationships. Details of this study in Norwegian children are now available online in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy........ ]]> http://medicineworld.org/stories/lead/3-2011/major-clue-in-long-term-memory-making.html http://medicineworld.org/stories/lead/3-2011/major-clue-in-long-term-memory-making.html Thu, 29 Dec 2011 01:08:18 GMT You may remember the color of your loved one's eyes for years. But how?. Researchers think that long-term potentiation (LTP) � the long-lasting increase of signals across a correlation between brain cells -- underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience........ ]]>
