Today archaeologists unearthed a 'Black Death' grave in London, containing more than a dozen skeletons of people suspected to have died from the plague. The victims are thought to have died during the 14th century and archaeologists anticipate finding many more as they excavate the site. http://medicalxpress.com/news/2013-03-paper-plague.html Diseases, Conditions, Syndromes Fri, 15 Mar 2013 12:27:58 EST news282569266 (Medical Xpress)—Testing asthmatic children for a specific gene could prevent their condition worsening, according to new research by scientists in Dundee and Brighton. http://medicalxpress.com/news/2013-01-gene-asthmatic-children-treatment.html Inflammatory disorders Tue, 08 Jan 2013 08:33:40 EST news276856410 Researchers at Case Western Reserve University School of Medicine have identified a molecule linked to more aggressive forms of breast cancer – a discovery that could point the way to potential cures. http://medicalxpress.com/news/2012-12-molecule-linked-late-stage-breast-cancer.html Cancer Mon, 17 Dec 2012 12:42:07 EST news274970519 Researchers show that the global epidemic of Clostridium difficile 027/NAP1/BI in the early to mid-2000s was caused by the spread of two different but highly related strains of the bacterium rather than one as was previously thought. The spread and persistence of both epidemics were driven by the acquisition of resistance to a frontline antibiotic. http://medicalxpress.com/news/2012-12-bugs-borders.html Genetics Sun, 09 Dec 2012 13:15:25 EST news274281308 Meet Ossie: a friendly green popsicle who has already been fired through the LHC and frozen to absolute zero in a bid to explain cutting edge science. http://medicalxpress.com/news/2012-10-animation-impact-genetics-patients.html Genetics Thu, 04 Oct 2012 07:32:12 EST news268554721 A new study has found that even though HIV diversifies widely within infected individuals over time, the virus strains that ultimately are passed on through heterosexual transmission often resemble the strain of virus that originally infected the transmitting partner. Learning the characteristics of these preferentially transmitted HIV strains may help advance HIV prevention efforts, particularly with regard to an HIV vaccine, according to the scientists who conducted the study. The research was led by Andrew D. Redd, Ph.D., staff scientist, and Thomas C. Quinn, M.D., senior investigator, both in the Laboratory of Immunoregulation of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. http://medicalxpress.com/news/2012-09-heterosexuals-transmitted-hiv-strains-resemble.html HIV & AIDS Thu, 20 Sep 2012 11:27:49 EST news267359257 (Medical Xpress)—One small change to the DNA sequence can cause more weighty changes to the human body, according to a new study released today. http://medicalxpress.com/news/2012-09-genetic-sequence-significantly-impact-bmi.html Genetics Mon, 17 Sep 2012 08:41:40 EST news267090088 A new study of the genetic makeup, or genome, of Ewing sarcoma, a rare cancer that strikes children, teenagers, and young adults, has produced multiple discoveries: a previously unknown sarcoma subtype, genetic factors related to long-term survival, and identification of a genetic change between the primary and metastatic stages of the disease that could lead to better, more targeted treatment. http://medicalxpress.com/news/2012-08-genomic-rare-children-cancer-yields.html Cancer Thu, 09 Aug 2012 09:26:20 EST news263723174 Genetics clearly plays a role in cancer development and progression, but the reason that a certain mutation leads to one cancer and not another is less clear. Furthermore, no links have been found between any cancer and a type of genetic change called "copy-number variants," or CNVs. Now, a new study published by Cell Press in The American Journal of Human Genetics on August 2 identifies CNVs associated with testicular cancer risk, but not with the risk of breast or colon cancer. http://medicalxpress.com/news/2012-08-genetic-copy-number-variants-cancer.html Genetics Thu, 02 Aug 2012 12:07:33 EST news263128040 In a new study from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, scientists describe successfully mutating specific genes of Chlamydia bacteria, which cause the most common sexually transmitted infection in the United States as well as a type of blindness common in developing nations. The procedure they used will help advance scientists' understanding of how these bacteria cause human disease and expedite the development of new strategies to prevent and control these infections. http://medicalxpress.com/news/2011-04-scientists-method-probe-genes-common.html Genetics Mon, 11 Apr 2011 16:26:36 EST news221757980 MIT cancer biologists have identified a genetic change that makes lung tumors more likely to spread to other parts of the body. The findings, to be published in the April 6 online issue of Nature, offers new insight into how lung cancers metastasize and could help identify drug targets to combat metastatic tumors, which account for 90 percent of cancer deaths. http://medicalxpress.com/news/2011-04-biologists-genetic-tumors-body.html Cancer Wed, 06 Apr 2011 13:01:54 EST news221313703
