Overcoming Reading Problems: How Can We Stlil Raed Words Wehn Teh Lettres Are Jmbuled Up?
Date: Mar-18-2013Researchers in the UK have taken an important step towards understanding how the human brain 'decodes' letters on a page to read a word. The work, funded by the Economic and Social Research Council (ESRC), will help psychologists unravel the subtle thinking mechanisms involved in reading, and could provide solutions for helping people who find it difficult to read, for example in conditions such as dyslexia...
A Step Closer To Explaining How Long-Term Infections Occur: Immune Finding Aids Quest For Vaccines To Beat Tropical Infections
Date: Mar-18-2013Scientists are a step closer to developing vaccines for a range of diseases that affect 200 million people, mainly in tropical south-east Asia, Africa and Central America. Researchers studying infections caused by parasitic worms - which can lead to diseases such as elephantiasis and river blindness - have shown how these can shut down a part of the immune system that might otherwise fight sickness. Preventing this immune reaction enables the infection to persist, causing chronic illness...
Learning How Brown Fat Cells Develop Offers Hope In The Fight Against Obesity
Date: Mar-18-2013Brown fat is a hot topic, pardon the pun. Brown fats cells, as opposed to white fat cells, make heat for the body, and are thought to have evolved to help mammals cope with the cold. But, their role in generating warmth might also be applied to coping with obesity and diabetes. The lab of Patrick Seale, PhD, at the Perelman School of Medicine, University of Pennsylvania, studies what proteins guide the development, differentiation, and function of fat cells...
New Sensor Developed For Methylated DNA
Date: Mar-18-2013Collaborators from Mayo-Illinois Alliance for Technology Based Healthcare have developed a new, single molecule test for detecting methylated DNA. Methylation -- the addition of a methyl group of molecules to a DNA strand -- is one of the ways gene expression is regulated. The findings appear in the journal Scientific Reports (Nature Publishing Group). "While nanopores have been studied for genomic sequencing and screening analysis, this new assay can potentially circumvent the need for some of the current processes in evaluating epigenetics-related diseases," says George Vasmatzis, Ph.D...
ASU Scholars Advocate Innovation In Regulatory, Payment Pathways For Personalized Medicine
Date: Mar-17-2013Two innovative programs designed to improve the availability of emerging medical technologies that can help patients receive more effective, efficient and personalized health care are advanced in a commentary written by a team of scientists and policy experts, including seven from Arizona State University, and published in Science Translational Medicine. The article, "Regulatory and Reimbursement Innovation," explores the benefits of coverage with evidence development (CED) and parallel review for the regulation and reimbursement of molecular diagnostics...
Ruminating About Stressful Events May Increase Inflammation In The Body
Date: Mar-17-2013Dwelling on negative and/or stressful events can raise levels of inflammation in the human body, researchers from Ohio University, Athens, USA, found. They will soon be presenting their findings at the Annual Meeting of the American Psychosomatic Society in Miami, Florida. Peggy Zoccola, assistant professor of psychology and team found that when their study participants were asked to dwell on a stressful experience, their C-reactive protein levels rose. C-reactive protein is a marker of tissue inflammation, i.e...
Opening Veins Does Not Help Multiple Sclerosis Patients
Date: Mar-17-2013Opening a Multiple Sclerosis patient's veins, a procedure often referred to as "liberation treatment" does not improve patient outcomes, researchers from the University at Buffalo revealed. In some cases patients ended up with worse symptoms, the investigators added. They will present their findings at an "Emerging Science" poster session at the annual American Academy of Neurology meeting in San Diego on March 20th, 2013. The researchers reported that while percutaneous transluminal venous angioplasty (PTCA) is safe, it did not improve blood flow in cerebrospinal veins...
Efforts To Reduce Kidney Care Disparities Should Take Race, Geographic Location Into Account
Date: Mar-17-2013Race and geographic area play important roles in determining whether a patient with chronic kidney disease (CKD) receives optimal care before developing kidney failure, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings suggest that policies aimed at eliminating disparities in kidney care must take these factors into account...
African Americans With Kidney Disease And Fluctuating Blood Pressure At Increased Risk Of Premature Death
Date: Mar-17-2013Large fluctuations in blood pressure from day to day are a warning sign for African Americans with kidney disease, indicating that they may face an increased risk of dying prematurely. That is the conclusion of a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings highlight the importance of routine blood pressure monitoring in patients with kidney disease, and they suggest that treatments that address large fluctuations may improve health. African Americans are more likely than whites to develop kidney disease...
Breast Cancer Survivors Advised To Eat Low Fat Dairy Products
Date: Mar-17-2013Patients who consume high-fat dairy products following breast cancer diagnosis increase their chances of dying from the disease years later, according to a study by Kaiser Permanente researchers. The study, published in the Journal of the National Cancer Institute, is the first to examine the relationship between high-fat and low-fat dairy consumption following a diagnosis of breast cancer and long-term breast cancer survival. Previous studies have shown that higher lifetime exposure to estrogen is a causal pathway to breast cancer...
