http://medicalxpress.com/ en-us Medical Xpress provides the latest news from New York University School of Medicine Chronic trauma can inflict lasting damage to brain regions associated with fear and anxiety. Previous imaging studies of people with post-traumatic stress disorder, or PTSD, have shown that these brain regions can over-or under-react in response to stressful tasks, such as recalling a traumatic event or reacting to a photo of a threatening face. Now, researchers at NYU School of Medicine have explored for the first time what happens in the brains of combat veterans with PTSD in the absence of external triggers. http://medicalxpress.com/news/2013-05-combat-veterans-post-traumatic-stress-disorder.html Neuroscience Sat, 18 May 2013 01:49:34 EST news288060554 In a first-of-its-kind effort to illuminate the biochemical impact of trauma, researchers at NYU Langone Medical Center have discovered a connection between the quantity of cannabinoid receptors in the human brain, known as CB1 receptors, and post-traumatic stress disorder, the chronic, disabling condition that can plague trauma victims with flashbacks, nightmares and emotional instability. Their findings, which appear online today in the journal Molecular Psychiatry, will also be presented this week at the annual meeting of the Society of Biological Psychiatry in San Francisco. http://medicalxpress.com/news/2013-05-brain-imaging-links-cannabinoid-receptors-post-traumatic.html Psychology & Psychiatry Tue, 14 May 2013 04:00:01 EST news287688428 In a landmark cancer study published online in Nature, researchers at NYU School of Medicine have unraveled a longstanding mystery about how pancreatic tumor cells feed themselves, opening up new therapeutic possibilities for a notoriously lethal disease with few treatment options. Pancreatic cancer kills nearly 38,000 Americans annually, making it a leading cause of cancer death. The life expectancy for most people diagnosed with it is less than a year. http://medicalxpress.com/news/2013-05-breakthrough-pancreatic-cancer-cells-ingest.html Cancer Mon, 13 May 2013 16:47:33 EST news287682443 Nitric oxide, the versatile gas that helps increase blood flow, transmit nerve signals, and regulate immune function, appears to perform one more biological feat— prolonging the life of an organism and fortifying it against environmental stress, according to a new study. http://medicalxpress.com/news/2013-02-bacteria-nitric-oxide-life-roundworms.html Medical research Thu, 14 Feb 2013 13:20:01 EST news280070122 After an intensive three-year hunt through the genome, medical researchers have pinpointed mutations that leads to drug resistance and relapse in the most common type of childhood cancer—the first time anyone has linked the disease's reemergence to specific genetic anomalies. http://medicalxpress.com/news/2013-02-mutations-linked-relapse-childhood-leukemia.html Genetics Sun, 03 Feb 2013 13:00:04 EST news279114848 Exposure to a chemical once used widely in plastic bottles and still found in aluminum cans appears to be associated with a biomarker for higher risk of heart and kidney disease in children and adolescents, according to an analysis of national survey data by NYU School of Medicine researchers published in the January 9, 2013, online issue of Kidney International, a Nature publication. http://medicalxpress.com/news/2013-01-bpa-linked-potential-adverse-effects.html Health Wed, 09 Jan 2013 09:40:05 EST news276946734 A new study by NYU School of Medicine researchers reveals that an especially virulent strain of the gut bacterium Helicobacter pylori (H. pylori) isn't implicated in the overall death rate of the U.S. population, and may even protect against stroke and some cancers. The findings, based a nationwide health survey of nearly 10,000 individuals over a period of some 12 years, are published online, January 9, in the journal Gut. http://medicalxpress.com/news/2013-01-bacterium.html Diseases, Conditions, Syndromes Wed, 09 Jan 2013 00:00:02 EST news276883496 A new study by NYU School of Medicine researchers suggests that an existing HIV drug called maraviroc could be a potential therapy for Staphylococcus aureus, a notorious and deadly pathogen linked to hundreds of thousands of hospitalizations each year.

They report their findings in a study published in the December issue of Nature Neuroscience. The discovery, featured on the journal's cover, could help advance treatments for spinal cord injuries and neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), which gradually kill neurons that control the movement of muscles needed to breathe, move, and eat. http://medicalxpress.com/news/2012-11-scientists-genetic-signature-vital-neurons.html Neuroscience Thu, 29 Nov 2012 13:36:21 EST news273418573 Researchers at NYU School of Medicine have discovered the protein product of a little-known gene may one day prove useful in identifying and monitoring the development of mesothelioma in early stages, when aggressive treatment can have an impact on the progression of disease and patient prognosis. http://medicalxpress.com/news/2012-10-high-blood-based-protein-specific-mesothelioma.html Cancer Wed, 10 Oct 2012 17:00:24 EST news269103854 Researchers at NYU School of Medicine have revealed a significant association between obesity and children and adolescents with higher concentrations of urinary bisphenol A (BPA), a synthetic chemical recently banned by the U.S. Food and Drug Administration (FDA) from sippy cups and baby bottles.
