A unique study of former guerrillas in Colombia has helped scientists redefine their understanding of the key regions of the brain involved in literacy. The study, funded by the Wellcome Trust and the Spanish Ministry of Education and Science, has enabled the researchers to see how brain structure changed after learning to read. http://www.physorg.com/news174744233.html Medicine & Health Wed, 14 Oct 2009 13:04:54 EST news174744233 People with chronic lung disease and asthma could soon be offered better treatment thanks to a new type of Magnetic Resonance Imaging (MRI) scan being pioneered at The University of Nottingham. http://www.physorg.com/news174648630.html Medicine & Health Tue, 13 Oct 2009 10:50:07 EST news174648630 A new technique in Magnetic Resonance Imaging dubbed "Hyper-SAGE" has the potential to detect ultra low concentrations of clincal targets, such as lung and other cancers. Development of Hyper-SAGE was led by one of the world's foremost authorities on MRI technology, Alexander Pines, a chemist who holds joint appointments with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, Berkeley. The key to this technique is xenon gas that has been zapped with laser light to "hyperpolarize" the spins of its atomic nuclei so that most are pointing in the same direction. http://www.physorg.com/news174319165.html Chemistry Fri, 09 Oct 2009 15:00:36 EST news174319165 Spontaneous brain activity formerly thought to be "white noise" measurably changes after a person learns a new task, researchers at Washington University School of Medicine in St. Louis and the University of Chieti, Italy, have shown. http://www.physorg.com/news174302671.html Medicine & Health Fri, 09 Oct 2009 10:25:17 EST news174302671 Researchers have long suspected that overweight people tend to have large fat deposits in their pancreases, but they've been unable to confirm or calculate how much fat resides there because of the organ's location. http://www.physorg.com/news172819152.html Medicine & Health Tue, 22 Sep 2009 06:40:02 EST news172819152 New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage. http://www.physorg.com/news170067953.html Medicine & Health Fri, 21 Aug 2009 10:06:34 EST news170067953 A new review says using magnetic resonance imaging (MRI) before surgery to assess the extent of early breast cancer has not been shown to improve surgical planning, reduce follow-up surgery, or reduce the risk of local recurrences. The review, appearing early online in CA: A Cancer Journal for Clinicians, says evidence shows that MRI increases the chances of more extensive surgery over conservative approaches, with no evidence that it improves surgical care or prognosis. http://www.physorg.com/news169373647.html Medicine & Health Thu, 13 Aug 2009 09:15:48 EST news169373647 Anorexic patients drastically reduce food intake and are often not capable of changing their behavior. This can lead to life-threatening weight loss. Using MRI technology, scientists at Heidelberg University Hospital have discovered for the first time processes in brain metabolism that explain this disturbed eating behavior. http://www.physorg.com/news168525822.html Medicine & Health Mon, 03 Aug 2009 14:10:01 EST news168525822 New research shows that childhood adversity is associated with diminished neural activity in brain regions implicated in the anticipation of possible rewards. http://www.physorg.com/news166903502.html Medicine & Health Wed, 15 Jul 2009 19:05:28 EST news166903502 Patients with multiple sclerosis who smoke appear to experience a more rapid progression of their disease, according to a report in the July issue of Archives of Neurology. http://www.physorg.com/news166721417.html Medicine & Health Mon, 13 Jul 2009 18:30:01 EST news166721417 A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib. http://www.physorg.com/news164982427.html Medicine & Health Tue, 23 Jun 2009 13:27:55 EST news164982427 The same techniques used to detect suspicious activity in airports, stadiums and other public places are now being used by the UCF researcher who invented them to find and measure potentially life-threatening brain tumors. http://www.physorg.com/news163163282.html Medicine & Health Tue, 02 Jun 2009 12:08:30 EST news163163282 A unique mother-daughter study that used magnetic resonance to measure breast density in younger women shows that percent of breast water could be linked to the risk of breast cancer in middle age and older. http://www.physorg.com/news160275336.html Medicine & Health Thu, 30 Apr 2009 01:55:57 EST news160275336 Donald O'Rourke, MD, Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine and colleagues, were able to accurately predict the specific genetic mutation that caused brain cancer in a group of patients studied using magnetic resonance imaging (MRI). The researchers presented their findings this week at the American Association for Cancer Research 100th Annual Meeting 2009. http://www.physorg.com/news159461589.html Medicine & Health Mon, 20 Apr 2009 15:53:34 EST news159461589 (PhysOrg.com) -- Magnetic resonance imaging (MRI) can serve as a very sensitive technique for detecting small tumors in the body, but it is not as good at identifying the edges of a tumor. Photoacoustic imaging tomography (PAT) is not as sensitive as MRI, but it excels at pinpointing the location of subsurface tissue structures, presumably including the edges of tumors. To take advantage of the best of both of these imaging techniques, a team of investigators led by Fanqing Frank Chen, Ph.D., University of California, San Francisco, has developed a `nanowonton` of cobalt and gold to create an imaging contrast agent for use with both MRI and PAT. http://www.physorg.com/news157309129.html Nanotechnology Thu, 26 Mar 2009 17:59:44 EST news157309129 Researchers announced today that a high-density genome wide analysis of participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI; www.adni-info.org) is more than 95% complete and that data will be shared with scientists around the world for further analysis. http://www.physorg.com/news156439115.html Medicine & Health Mon, 16 Mar 2009 16:19:26 EST news156439115 A handful of proteins, detected in incredibly tiny amounts, may one day help doctors distinguish between a harmless lesion in the pancreas and a potentially deadly one, say researchers at Fox Chase Cancer Center. http://www.physorg.com/news155921088.html Medicine & Health Tue, 10 Mar 2009 16:25:21 EST news155921088 Studies on the influence of quadriceps strength on knee osteoarthritis (OA), one of the leading causes of disability among the elderly, have shown conflicting results.
