For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream. http://www.physorg.com/news176652011.html Medicine & Health Thu, 05 Nov 2009 14:01:57 EST news176652011 One of the many mysteries of Alzheimer's disease is how protein-like snippets called amyloid-beta peptides, which clump together to form plaques in the brain, may cause cell death, leading to the disease's devastating symptoms of memory loss and other mental difficulties. http://www.physorg.com/news176551843.html Chemistry Wed, 04 Nov 2009 10:21:54 EST news176551843 Inflammatory response of brain cells -as indicated by a molecular imaging technique -could tell researchers more about why certain neurologic disorders, such as migraine headaches and psychosis in schizophrenic patients, occur and provide insight into how to best treat them, according to two studies published in the November issue of the Journal of Nuclear Medicine. http://www.physorg.com/news176119933.html Medicine & Health Fri, 30 Oct 2009 11:12:48 EST news176119933 The Center for the Study of Traumatic Encephalopathy (CSTE) at Boston University School of Medicine (BUSM) announced today that a recently deceased member of the NFL Hall of Fame suffered from the degenerative brain disease Chronic Traumatic Encephalopathy (CTE) when he died, becoming the 10th former NFL player diagnosed with the disease. http://www.physorg.com/news175946062.html Medicine & Health Wed, 28 Oct 2009 11:10:01 EST news175946062 Researchers at Duke University Medical Center have uncovered a new genetic signature that correlates strongly with autism and which doesn't involve changes to the DNA sequence itself. Rather, the changes are in the way the genes are turned on and off. The finding may suggest new approaches to diagnosis and treatment of autism. http://www.physorg.com/news175374486.html Medicine & Health Wed, 21 Oct 2009 20:09:37 EST news175374486 (PhysOrg.com) -- The eyes may be the windows to the soul, but new research indicates they also may mirror a brain ravaged by Alzheimer's disease. http://www.physorg.com/news175347660.html Medicine & Health Wed, 21 Oct 2009 12:54:21 EST news175347660 Scientists have countered findings of previous clinical trials by showing that giving supplemental oxygen to animals during a stroke can reduce damage to brain tissue surrounding the clot. http://www.physorg.com/news175190352.html Medicine & Health Mon, 19 Oct 2009 17:10:10 EST news175190352 As doctors begin to test progesterone for traumatic brain injury at sites across the country, researchers are looking ahead to optimizing the hormone's effectiveness. http://www.physorg.com/news175178201.html Medicine & Health Mon, 19 Oct 2009 14:00:01 EST news175178201 (PhysOrg.com) -- Neurologists at the University at Buffalo are beginning a research study that could overturn the prevailing wisdom on the cause of multiple sclerosis (MS). The researchers will test the possibility that the symptoms of MS result from narrowing of the primary veins outside the skull, a condition called "chronic cerebrospinal venous insufficiency," or CCSVI. http://www.physorg.com/news174760709.html Medicine & Health Wed, 14 Oct 2009 17:39:06 EST news174760709 Specific cells within the immune system could help explain why younger people are more susceptible to variant CJD, scientists believe. http://www.physorg.com/news174735267.html Medicine & Health Wed, 14 Oct 2009 10:34:53 EST news174735267 Initial chemotherapy alone after surgery is just as successful as initial radiation therapy for patients from whom a very malignant brain tumor (anaplastic glioma) was removed. With this treatment, the patients survive on average > 30 months without a recurrence. A study conducted by the Neurooncology Working Group of the German Cancer Society led by researchers from Heidelberg and Zürich showed that patients in primary therapy benefit to the same extent from chemotherapy alone as from radiation alone. http://www.physorg.com/news173623865.html Medicine & Health Thu, 01 Oct 2009 15:00:01 EST news173623865 The National Institutes of Health has awarded Rush University Medical Center approximately $5.5 million in grants to study how epigenetic changes - chemical modifications to genes that result from diet, aging, stress, or environmental exposures - define and contribute to memory formation and cognitive decline. Results from the studies could profoundly alter the way the medical community understands, diagnoses, and treats Alzheimer's disease, according to the researchers. http://www.physorg.com/news173552904.html Medicine & Health Thu, 01 Oct 2009 01:20:01 EST news173552904 ANN ARBOR, Mich.---Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan.

They have been studying the impacts of nerve growth factors in the treatment of PD, and their latest results show that a certain growth factor can be used to halt the progress of damage brought on by a nerve poison and possibly even restore the function of damaged cells. http://www.physorg.com/news170676873.html Medicine & Health Fri, 28 Aug 2009 11:40:01 EST news170676873 Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals. http://www.physorg.com/news170676756.html Medicine & Health Fri, 28 Aug 2009 11:30:01 EST news170676756 New research on the effects of blast waves could lead to an enhanced understanding of head injuries and improved military helmet design. http://www.physorg.com/news170512369.html Physics Wed, 26 Aug 2009 13:44:06 EST news170512369 Obesity is on a rampage, with the World Health Organization pegging the numbers at more than 300 million worldwide, with a billion more overweight.

It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue. http://www.physorg.com/news168537401.html Nanotechnology Mon, 03 Aug 2009 17:20:01 EST news168537401 Researchers have discovered that the enzyme, endothelin converting enzyme-2 (ECE-2), may cause the decrease in blood flow in the brain seen in Alzheimer's disease and contribute to progression of the disease. http://www.physorg.com/news167919992.html Medicine & Health Mon, 27 Jul 2009 13:40:01 EST news167919992
