(Medical Xpress)—Some racial groups are more likely to bear the brunt of extreme heat waves because of where they live, according to a new study by researchers at the University of California, Berkeley. http://medicalxpress.com/news/2013-05-racial-minorities-front-lines.html Health Tue, 14 May 2013 08:10:01 EST news287736937 Low birth weights are more prevalent among Brazilians with African ancestry and may be attributed to less use of prenatal care facilities and where those ethnic groups live, according to a new study. http://medicalxpress.com/news/2013-02-african-ancestry-babies-prenatal-brazil.html Health Tue, 26 Feb 2013 16:20:28 EST news281118022 Complex socioeconomic and residential factors may account for differences in survival between Black and White kidney failure patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

The findings appear in today's online issue of Nature Cell Biology. http://medicalxpress.com/news/2012-12-unmasks-healthy-life-span.html Medical research Mon, 17 Dec 2012 12:38:32 EST news274970304 Moving from a high-poverty to lower-poverty neighborhood spurs long-term gains in the physical and mental health of low-income adults, as well as a substantial increase in their happiness, despite not improving economic self-sufficiency, according to a new study published in the Sept. 20 issue of Science by researchers at the University of Chicago and partners at other institutions. http://medicalxpress.com/news/2012-09-impoverished-neighborhoods-boosts-physical-mental.html Health Thu, 20 Sep 2012 14:00:01 EST news267367033 Researchers from our Department of Education say attitudes in coaching towards disabled people need to change in order for more people to engage in sport. http://medicalxpress.com/news/2012-09-disabled-athletes-segregation.html Health Mon, 03 Sep 2012 07:47:19 EST news265877233 Cohesin is a ring-shaped protein complex involved in the spatial organization of the genome and in mitotic chromosome structure. Vertebrate somatic cells have two versions of cohesin that contain either SA1 or SA2, but their functional specificity has been largely ignored. Researchers of the Spanish National Cancer Research Centre (CNIO) under the direction of Ana Losada have identified new functions of cohesin SA1 that are relevant for two human diseases, cancer and Cornelia de Lange Syndrome (CdLS). These results are published in two papers that appear this week back-to-back in EMBO Journal. http://medicalxpress.com/news/2012-05-functions-cohesin-relevant-human-disease.html Cancer Thu, 03 May 2012 10:50:01 EST news255259623 The development of more effective cancer drugs could be a step nearer thanks to the discovery, by scientists at Warwick Medical School, of how an inbuilt 'security check' operates to guarantee cells divide with the correct number of chromosomes. http://medicalxpress.com/news/2012-04-warwick-scientists-uncover-checkpoint-proteins.html Cancer Fri, 20 Apr 2012 11:18:25 EST news254139485 Each time a cell divides -- and it takes millions of cell divisions to create a fully grown human body from a single fertilized cell -- its chromosomes have to be accurately divvied up between both daughter cells. Researchers at the Stowers Institute for Medical Research used, ironically enough, the single-celled organism Saccharomyces cerevisiae -- commonly known as baker's yeast -- to gain new insight into the process by which chromosomes are physically segregated during cell division. http://medicalxpress.com/news/2011-11-gain-insight-chromosome.html Genetics Thu, 17 Nov 2011 18:40:02 EST news240774017 We live in a world with people from diverse cultures, different societies and varied communities. Unfortunately, all those differences can sometimes result in segregation and discrimination. Reducing prejudice and creating more open minded societies has been the focal point of recent research and now, a new study in this field suggests that mental simulation is a key component of behavioral change strategies. Though this approach is controversial, authors Richard J. Crisp, Michèle D. Birtel, and Rose Meleady at the University of Kent, believe that this will assist in reducing prejudice and discrimination. http://medicalxpress.com/news/2011-08-mental-simulations-social-thought-action.html Psychology & Psychiatry Fri, 05 Aug 2011 11:00:01 EST news231759938 How researchers classify and quantify causes of death across a population has evolved in recent decades. In addition to long-recognized physiological causes such as heart attack and cancer, the role of behavioral factors—including smoking, dietary patterns and inactivity—began to be quantified in the 1990s. More recent research has begun to look at the contribution of social factors to U.S. mortality. In the first comprehensive analysis of such studies, researchers at Columbia University's Mailman School of Public Health found that poverty, low levels of education, poor social support and other social factors contribute about as many deaths in the U.S. as such familiar causes as heart attacks, strokes and lung cancer. http://medicalxpress.com/news/2011-06-deaths-poverty-social-factors.html Health Thu, 16 Jun 2011 16:00:04 EST news227450591
