Previous studies have shown a link between low vitamin D status and heart disease. Now a new study shows that patients with high blood pressure who possess a gene variant that affects an enzyme critical to normal vitamin D activation are twice as likely as those without the variant to have congestive heart failure. http://www.physorg.com/news178909907.html Medicine & Health Tue, 01 Dec 2009 17:12:48 EST news178909907 Do stressful situations make your blood pressure rise? If so, your phosducin gene could be to blame according to a team of researchers, at the University of Freiburg, Germany, and the Medical College of Wisconsin, Milwaukee, that has identified a role for the protein generated by the phosducin gene in modulating blood pressure in response to stress in both mice and humans. http://www.physorg.com/news178224266.html Medicine & Health Mon, 23 Nov 2009 19:20:01 EST news178224266 Bad drivers may in part have their genes to blame, suggests a new study by UC Irvine neuroscientists. http://www.physorg.com/news175951284.html Medicine & Health Wed, 28 Oct 2009 12:22:24 EST news175951284 (PhysOrg.com) -- Cancer predisposition resulting from the presence of a specific gene variant shows a strong gender bias, researchers at the University of Cincinnati (UC) have demonstrated. http://www.physorg.com/news172770958.html Medicine & Health Mon, 21 Sep 2009 16:56:19 EST news172770958 An international team, led by researchers from the University of California, San Diego School of Medicine and the National Eye Institute, has discovered gene variants for glaucoma in a black population.

Recent research has convincingly shown that there is a strong interaction between genetic inheritance and environment for development of personality and behaviour. It appears to be common knowledge that childhood maltreatment often causes psychiatric problems (e.g. depression or anxiety) or behavioural problems (e.g. aggression or antisocial behaviour) later in life. The risk for such a development is, however, different between individuals and can to a large extent be explained by genetic factors. http://www.physorg.com/news172072045.html Medicine & Health Sun, 13 Sep 2009 14:48:27 EST news172072045 (PhysOrg.com) -- The gene most closely linked to an increased risk of developing Alzheimer's disease affects brain activity in young adults -- much earlier in life than previously reported -- according to researchers at Duke University Medical Center and The Pennsylvania State University. http://www.physorg.com/news171816576.html Medicine & Health Thu, 10 Sep 2009 16:00:09 EST news171816576 Patients with a certain genetic variation who received the antiplatelet drug clopidogrel had a decreased platelet response to treatment and among those who had percutaneous coronary intervention (procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) had an increased risk of having a cardiovascular event in the following year than patients who did not have this variant, according to a study in the August 26 issue of JAMA. http://www.physorg.com/news170438381.html Medicine & Health Tue, 25 Aug 2009 17:50:01 EST news170438381 Researchers at the University of Maryland School of Medicine have identified a common gene variant carried by as many as a third of the general population that is believed to play a major role in determining why people do not respond to a popular anti-clotting medication, Plavix. If the medication doesn't work, patients are at increased risk for subsequent heart attacks, strokes and other serious cardiovascular problems. http://www.physorg.com/news170436030.html Medicine & Health Tue, 25 Aug 2009 16:21:50 EST news170436030 Computational biologists at Carnegie Mellon University have developed an analytical technique to detect the multiple genetic variations that contribute to complex disease syndromes such as diabetes, asthma and cancer, which are characterized by multiple clinical and molecular traits. http://www.physorg.com/news168843451.html Medicine & Health Fri, 07 Aug 2009 06:10:01 EST news168843451 Pediatric researchers have found that a gene previously shown to be involved in the development of type 2 diabetes also predisposes children to having a lower birth weight. The finding sheds light on a possible genetic influence on how prenatal events may set the stage for developing diabetes in later childhood or adulthood. http://www.physorg.com/news168093004.html Medicine & Health Wed, 29 Jul 2009 13:40:04 EST news168093004 California and Arizona researchers have identified a gene variant that carries nearly twice the risk of developing an increasingly common type of blood cancer, according to a study published online today by the science journal Nature Genetics. http://www.physorg.com/news167314531.html Medicine & Health Mon, 20 Jul 2009 13:16:02 EST news167314531 Finnish Academy Professors Lauri Aaltonen and Jussi Taipale have identified and described a mechanism whereby a single-base change in the human genome increases the risk of colorectal cancer. http://www.physorg.com/news165490050.html Medicine & Health Mon, 29 Jun 2009 11:20:04 EST news165490050 New research indicates that natural selection may shape the human genome much more slowly than previously thought. Other factors -- the movements of humans within and among continents, the expansions and contractions of populations, and the vagaries of genetic chance - have heavily influenced the distribution of genetic variations in populations around the world. The study, conducted by a team from the Howard Hughes Medical Institute, the University of Chicago, the University of California and Stanford University, is published June 5 in the open-access journal PLoS Genetics. http://www.physorg.com/news163414831.html Medicine & Health Fri, 05 Jun 2009 10:01:04 EST news163414831 Music is social communication between individuals -- humming of lullabies attach infant to parent and singing or playing music adds croup cohesion. The neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior, suggests a recent Finnish study. The study gives new information about genetic background of musical aptitude. http://www.physorg.com/news162550708.html Medicine & Health Tue, 26 May 2009 09:58:50 EST news162550708 Researchers from the Peninsula Medical School, along with collaborators from research institutions across Europe and the United States, have for the first time identified two genes that are involved in determining when girls begin menstruation.
