Puerto Rican children who have asthma are more likely to be exposed to violence and to have changes in a gene that is associated with stress, according to a new study led by researchers at Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine. The study, which is the first to examine the links between asthma, stress and gene variation, was recently published in the American Journal of Respiratory and Critical Care Medicine. http://medicalxpress.com/news/2013-03-exposure-violence-gene-linked-asthma.html Diseases, Conditions, Syndromes Tue, 19 Mar 2013 10:15:57 EST news282906935 (Medical Xpress)—A possible link between colour vision and the development of myopia - or near-sightedness - has been discovered by an international group, including a researcher from The University of Western Australia. http://medicalxpress.com/news/2013-03-colour-vision-link-myopia.html Ophthalmology Fri, 01 Mar 2013 07:23:18 EST news281344934 (Medical Xpress)—Most parents would agree that raising a generous child is an admirable goal—but how, exactly, is that accomplished? New results from the University of Notre Dame's Science of Generosity initiative, which funds generosity research around the world, sheds light on how generosity and related behaviors—such as kindness, caring and empathy—develop, or don't develop, in children from 2 years old through adolescence. http://medicalxpress.com/news/2013-02-link-gene-selfish-behavior-kids.html Psychology & Psychiatry Wed, 27 Feb 2013 10:06:31 EST news281181941 (Medical Xpress)—A multinational research project led by the Universities of Dundee and Glasgow has identified a genetic determinant of hypertension (or high blood pressure), which could inform treatment of the condition for thousands of patients. http://medicalxpress.com/news/2012-11-genetic-hypertension.html Cardiology Thu, 22 Nov 2012 09:20:01 EST news272795207 (Medical Xpress)—The prevailing wisdom has been that every cell in the body contains identical DNA. However, a new study of stem cells derived from the skin has found that genetic variations are widespread in the body's tissues, a finding with profound implications for genetic screening, according to Yale School of Medicine researchers. http://medicalxpress.com/news/2012-11-skin-cells-reveal-dna-genetic.html Genetics Mon, 19 Nov 2012 09:15:14 EST news272538907 (Medical Xpress)—A new study from the University of Alberta shows that your genes could be the reason your allergic asthma or hay fever is so severe. http://medicalxpress.com/news/2012-10-severe-allergic-asthma-linked-gene.html Inflammatory disorders Mon, 15 Oct 2012 07:44:23 EST news269505857 A single genetic variant in kidney donors' cells may help determine whether their transplanted organs will survive long term, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings provide new information that might be used to improve transplant longevity by revealing that the genetic make-up of kidney transplant donors affects the survival of transplanted organs. http://medicalxpress.com/news/2012-10-gene-variant-donors-affect-survival.html Other Thu, 11 Oct 2012 17:00:01 EST news269192994 (Medical Xpress)—Over the past decade, researchers have made great strides in identifying genes that lead to an increased risk of autism spectrum disorders (ASD), which result in a continuum of social deficits, communication difficulties and cognitive delays. But it's still critical to determine how exactly these genetic risk factors impact the brain's structure and function so that better treatments and interventions can be developed. http://medicalxpress.com/news/2012-09-common-gene-mutation-affects-kids.html Autism spectrum disorders Fri, 14 Sep 2012 08:59:37 EST news266831918 Everybody is talking about Internet addiction. Medically, this phenomenon has not yet been as clearly described as nicotine or alcohol dependency. But a study conducted by researchers from the University of Bonn and the Central Institute of Mental Health (ZI) in Mannheim now provides indications that there are molecular-genetic connections in Internet addiction, too. The results is reported in the Journal of Addiction Medicine. The print version appears in the September issue. http://medicalxpress.com/news/2012-08-internet-addictioncauses-molecular.html Addiction Wed, 29 Aug 2012 11:10:25 EST news265457420 (Medical Xpress) -- Researchers from Newcastle University have identified a gene variation carried by 20% of the population which can significantly affect how patients with a rare type of blood cancer will respond to treatment. http://medicalxpress.com/news/2012-01-scientists-genetic-key-cancer-patients.html Cancer Thu, 05 Jan 2012 09:20:01 EST news244976719 Abraham Kovoor was studying a brain protein, called RGS9 2, that he had previously related to the involuntary, random and repetitive body movements that are side effects of drugs used to treat Parkinson's disease and schizophrenia. http://medicalxpress.com/news/2012-01-gene-body-weight.html Genetics Wed, 04 Jan 2012 14:30:05 EST news244907666 (Medical Xpress) -- A study by researchers at UC Davis has found that pregnant women with a particular gene variation are more likely to produce auto-antibodies to the brains of their developing fetuses and that the children of these mothers are at greater risk of later being diagnosed with autism. http://medicalxpress.com/news/2011-10-genetic-variant-auto-antibodies-linked-autism.html Psychology & Psychiatry Wed, 19 Oct 2011 07:06:34 EST news238226771
