(Medical Xpress)—Exposure to noise, for example from road traffic, may adversely affect the cardiovascular system. Until now, underlying mechanisms linking noise to elevated cardiovascular risk have rarely been explored in epidemiological studies. Scientists of Helmholtz Zentrum München have now shown that exposure to noise during everyday life influences heart rate variability, i.e. the ability of the heart to adjust the rate at which it beats to acute events. The results were published in the journal Environmental Health Perspectives. http://medicalxpress.com/news/2013-05-exposure-everyday-noise-heart-variability.html Health Thu, 02 May 2013 07:20:01 EST news286695411 University of North Carolina researchers have discovered that disrupting a gene that acts as a regulatory switch to turn on other genes can keep blood vessels from forming and developing properly. http://medicalxpress.com/news/2013-04-uncovers-molecular-role-gene-linked.html Medical research Mon, 29 Apr 2013 12:41:09 EST news286458050 When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of that DNA doing? http://medicalxpress.com/news/2013-01-non-coding-rna-molecules-differentiation-embryonic.html Medical research Fri, 25 Jan 2013 07:44:49 EST news278322283 A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems. http://medicalxpress.com/news/2013-01-viral-reactivation-link-stress-heart.html Cardiology Tue, 22 Jan 2013 15:09:03 EST news278089734 One of life's certainties is that everyone ages. However, it's also certain that not everyone ages at the same rate. According to recent research being presented this week, the cardiovascular system of people with type 2 diabetes shows signs of aging significantly earlier than those without the disease. However, exercise can help to slow down this premature aging, bringing the aging of type 2 diabetes patients' cardiovascular systems closer to that of people without the disease, says researcher Amy Huebschmann of the University of Colorado School of Medicine. She will be presenting these findings she developed with colleagues Wendy Kohrt and Judith Regensteiner, both from the same institution. http://medicalxpress.com/news/2012-10-incorporating-regular-physical-diabetic-adults.html Diabetes Thu, 11 Oct 2012 08:10:01 EST news269160908 Researchers from the Peninsula College of Medicine and Dentistry (PCMD), University of Exeter, will present the findings of a new study suggesting a link between binge drinking in older adults and the risk of developing dementia. http://medicalxpress.com/news/2012-07-binge-cognitive-decline-older-adults.html Alzheimer's disease & dementia Wed, 18 Jul 2012 04:00:01 EST news261759344 Turkish surgeons had to remove one leg from a patient who underwent a quadruple limb transplant after his heart and vascular system failed to sustain the limb, the hospital said on Sunday. http://medicalxpress.com/news/2012-02-complication-turkey-quadruple-limb-transplant.html Surgery Sun, 26 Feb 2012 13:31:18 EST news249485468 (Medical Xpress) -- Being involved in a healthy, loving relationship is good for the heart, says Vanderbilt Heart and Vascular Institute cardiologist Julie Damp, M.D. “There are a couple of different theories behind why that might be,” Damp said. http://medicalxpress.com/news/2012-02-chocolate-good-heart-cardiologist.html Health Tue, 14 Feb 2012 06:20:01 EST news248420078 New research explains how cells regulate their bonds during the development of new blood vessels. For the first time, the role of the protein Raf-1 in determining the strength of the bond between cells has been shown. If Raf-1 is not present, the cells cannot stick together and the formation of new blood vessels is inhibited. This discovery may one day lead to new approaches to cancer treatment. http://medicalxpress.com/news/2012-01-essential-protein-formation-blood-vessels.html Medical research Tue, 17 Jan 2012 07:40:01 EST news246007679 A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to Penn State researchers. The compound -- delta-12-protaglandin J3, or D12-PGJ3 -- targeted and killed the stem cells of chronic myelogenous leukemia, or CML, in mice, said Sandeep Prabhu, associate professor of immunology and molecular toxicology in the Department of Veterinary and Medical Sciences. The compound is produced from EPA -- Eicosapentaenoic Acid -- an Omega-3 fatty acid found in fish and in fish oil, he said. http://medicalxpress.com/news/2011-12-fish-oil-key-leukemia.html Cancer Thu, 22 Dec 2011 09:50:04 EST news243769771 Siestas, a health diet -- and genetics -- could explain why people on the tiny Aegean island of Ikaria live so long, said a study by Greek cardiologists released Wednesday. http://medicalxpress.com/news/2011-07-sea-diet-siesta-greek-island.html Health Wed, 13 Jul 2011 12:45:07 EST news229779885 A new book edited by researchers at Worcester Polytechnic Institute (WPI) and the Stony Brook University School of Medicine provides a comprehensive look at the science and application of cellular therapies aimed at the leading cause of death---heart disease.
