In recent years they have emerged as disease biomarkers. miRNA profiles have been used to establish tissue origin for cancers of unknown primary origin, determine prognosis, monitor therapeutic responses and screen for disease, but clinically tractable, diagnostic methods for monitoring miRNA expression in patient samples are not currently available. http://medicalxpress.com/news/2013-05-fluorescent-tools-cancer-diagnosis.html Cancer Fri, 24 May 2013 12:33:15 EST news288617567 Cancer cells spread and grow by avoiding detection and destruction by the immune system. Stimulation of the immune system can help to eliminate cancer cells; however, there are many factors that cause the immune system to ignore cancer cells. Regulatory T cells are immune cells that function to suppress the immune system response. http://medicalxpress.com/news/2013-05-modulating-immune-combat-metastatic-cancer.html Cancer Fri, 24 May 2013 12:31:48 EST news288617502 Women at a particular stage in their monthly menstrual cycle may be more vulnerable to some of the psychological side-effects associated with stressful experiences, according to a study from UCL. http://medicalxpress.com/news/2013-05-hormone-key-psychological-disorders-women.html Psychology & Psychiatry Fri, 24 May 2013 12:05:42 EST news288615932 (HealthDay)—Menopausal hormone therapy should not be used for prevention of coronary heart disease, according to a Committee Opinion from the American College of Obstetricians and Gynecologists (ACOG) published in the June issue of Obstetrics & Gynecology. http://medicalxpress.com/news/2013-05-acog-hormone-therapy-chd.html Obstetrics & gynaecology Fri, 24 May 2013 12:00:01 EST news288614811 After studying noise in one French Quarter neighborhood of New Orleans to determine whether or not noise levels exceeded municipal ordinances, Annette Hurley, PhD, Assistant Professor of Audiology at LSU Health Sciences Center New Orleans, and Eric Arriaga, a third-year LSUHSC doctor of audiology student, recommend that people use today's technology to protect their own hearing health.

Specific areas of the brain become progressively affected as the disease develops and advances. The mechanism underlying this pathological progression is poorly understood but could result from spreading of the protein (or abnormal forms of it) along nerve projections connecting lower to upper brain regions. Scientists at the German Center for Neurodegenerative Diseases (DZNE) in Bonn have developed a novel experimental model that reproduces for the first time this pattern of alpha-synuclein brain spreading and provides important clues on the mechanisms underlying this pathological process. They triggered the production of human alpha-synuclein in the lower rat brain and were able to trace the spreading of this protein toward higher brain regions. The new experimental paradigm could promote the development of ways to halt or slow down disease development in humans. http://medicalxpress.com/news/2013-05-animal-insights-mechanisms-parkinson-disease.html Parkinson's & Movement disorders Fri, 24 May 2013 11:38:10 EST news288614282 The news about youth and diabetes keeps getting worse.

To understand what happens in the course of infections, diseases or normal bodily functions, scientists would need to examine individual cells and their activity directly in the tissue. The development of new microscopes and fluorescent dyes in recent years has brought this scientific dream tantalisingly close. Scientists from the Max Planck Institute of Neurobiology in Martinsried have now presented not one, but two studies introducing new indicator molecules which can visualise the activation of T cells. Their findings provide new insight into the role of these cells in the autoimmune disease multiple sclerosis (MS). The new indicators are set to be an important tool in the study of other immune reactions as well. http://medicalxpress.com/news/2013-05-immune-cell-multiple-sclerosis.html Immunology Fri, 24 May 2013 11:35:22 EST news288614094 Saudi Arabia said Friday it would send samples taken from animals possibly infected with a deadly SARS-like virus to the United States for testing in a bid to find the source of disease. http://medicalxpress.com/news/2013-05-saudi-animal-samples-coronavirus-probe.html Diseases, Conditions, Syndromes Fri, 24 May 2013 09:50:01 EST news288605780 New research presented today shows that formation of new neurons in the hippocampus - a brain region known for its importance in learning and remembering - could cause forgetting of old memories by causing a reorganization of existing brain circuits. Drs. Paul Frankland and Sheena Josselyn, both from the Hospital for Sick Children in Toronto, argue this reorganization could have the positive effect of clearing old memories, reducing interference and thereby increasing capacity for new learning. These results were presented at the 2013 Canadian Neuroscience Meeting, the annual meeting of the Canadian Association for Neuroscience - Association Canadienne des Neurosciences (CAN-ACN). http://medicalxpress.com/news/2013-05-neuron-formation-capacity-expense-memories.html Neuroscience Fri, 24 May 2013 09:30:03 EST news288605755 Ernie Pyle – an iconic war correspondent in World War II – reportedly said "There are no atheists in foxholes."

After all, it is the accumulation of A-beta that causes the known plaques in the brains of Alzheimer's patients. Starting point for the formation of A-beta is APP. Alessia Soldano and Bassem Hassan (VIB/KU Leuven) were the first to unravel the function of APPL – the fruit-fly version of APP – in the brain of healthy fruit flies. http://medicalxpress.com/news/2013-05-strategy-required-alzheimer-drugs.html Alzheimer's disease & dementia Fri, 24 May 2013 08:42:11 EST news288603723 One of the major frontiers of modern science is a comprehensive understanding of the human brain and its functions to guide the development of new technologies in information and communication.
