Researchers from Yale University School of Medicine have demonstrated that vesicular stomatitis virus (VSV) is highly competent at finding, infecting, and killing human melanoma cells, both in vitro and in animal models, while having little propensity to infect non-cancerous cells. http://medicalxpress.com/news/2013-04-virus-melanoma-animal-cells.html Medical research Tue, 23 Apr 2013 12:48:07 EST news285940080 There are cells in your brain that recognize very specific places, and have that as one of their main jobs. These cells, called place cells, are found in an area behind your temple called the hippocampus. While these cells must be sent information from nearby cells to do their job, so far no one has been able to determine exactly what kind of nerve cells, or neurons, work with place cells to craft the code they create for each location. Neurons come in many different types with specialized functions. Some respond to edges and borders, others to specific locations, others act like a compass and react to which way you turn your head. http://medicalxpress.com/news/2013-04-scientists-cells-brain-flipping-neural.html Neuroscience Thu, 04 Apr 2013 14:00:07 EST news284300102 Doctors may in the future be able to take a blood test to determine if a patient is suicidal, hopefully decreasing the number of people taking their own lives. http://medicalxpress.com/news/2013-02-suicide-critical.html Psychology & Psychiatry Wed, 20 Feb 2013 08:10:04 EST news280570179 Researchers at Imperial College London have discovered a new way in which a very common childhood disease could be treated. In the first year of life, 65 per cent of babies get infected by Respiratory Syncytial Virus (RSV). This causes bronchiolitis, and is thought to kill nearly 200,000 children every year worldwide. http://medicalxpress.com/news/2013-02-respiratory-syncytial-virus-treatment-viral.html Diseases, Conditions, Syndromes Mon, 04 Feb 2013 15:00:11 EST news279196354 (Medical Xpress)—Scientists have identified molecular signals that control whether embryos are accepted by the womb, and that appear to function abnormally in women who have suffered repeated miscarriages. http://medicalxpress.com/news/2013-01-scientists-molecular-women-prone-miscarriage.html Medical research Thu, 03 Jan 2013 10:15:24 EST news276430518 (Medical Xpress)—Researchers have found the first proof that a chemical in the brain called glutamate is linked to suicidal behavior, offering new hope for efforts to prevent people from taking their own lives. http://medicalxpress.com/news/2012-12-countering-brain-chemical-suicides.html Psychology & Psychiatry Fri, 14 Dec 2012 09:37:55 EST news274700268 Unraveling the mechanism that ovarian cancer cells use to change normal cells around them into cells that promote tumor growth has identified several new targets for treatment of this deadly disease. http://medicalxpress.com/news/2012-11-micrornas-cells-cancer.html Cancer Wed, 21 Nov 2012 10:00:01 EST news272714077 (Medical Xpress)—A thin, flexible electrode developed at the University of Michigan is 10 times smaller than the nearest competition and could make long-term measurements of neural activity practical at last. http://medicalxpress.com/news/2012-11-brain-implant-slim-electrode-cozies.html Neuroscience Sun, 11 Nov 2012 13:03:52 EST news271861417 A low dose of the sedative clonazepam alleviated autistic-like behavior in mice with a mutation that causes Dravet syndrome in humans, University of Washington researchers have shown. http://medicalxpress.com/news/2012-08-low-dose-sedative-alleviates-autistic-like-behavior.html Diseases, Conditions, Syndromes Wed, 22 Aug 2012 13:20:51 EST news264860438 It has long been known that cancer is a disease of aging, but a molecular link between the two has remained elusive. http://medicalxpress.com/news/2012-06-aging-cells-fuels-tumor-growth.html Cancer Thu, 14 Jun 2012 14:59:36 EST news258904683 When most groups of mammalian cells are faced with a shortage of nutrients or oxygen, the phrase "every man for himself" is more apt than "all for one, one for all." Unlike colonies of bacteria, which often cooperate to thrive as a group, mammalian cells have never been observed to help one another out. But a new study led by a researcher at the Stanford University School of Medicine has shown that certain human embryonic stem cells, in times of stress, produce molecules that not only benefit themselves, but also help nearby cells survive. http://medicalxpress.com/news/2012-06-unusual-altruistic-stem-cell-behavior.html Cancer Mon, 11 Jun 2012 09:49:01 EST news258626920 Like snakes, tumour cells shed their skin. Cancer is not a static disease but during its development the disease accumulates changes to evade natural defences adapting to new environmental circumstances, protecting against chemotherapy and radiotherapy and invading neighbouring organs, eventually causing metastasis. http://medicalxpress.com/news/2011-09-cancer-cells.html Cancer Fri, 02 Sep 2011 09:19:11 EST news234173936 How is it that a disc-like cluster of cells transforms within the first month of pregnancy into an elongated embryo?
