(PhysOrg.com) -- A portable 'lab on a chip' that can identify target molecules in blood samples has been created by European researchers. It is being used to measure fertility hormones and detect the genes associated with certain types of cancer. http://www.physorg.com/news166856463.html Chemistry Wed, 15 Jul 2009 06:01:36 EST news166856463 The Medical College of Georgia is part of a large national study examining the genes of 10,000 patients with schizophrenia and 10,000 healthy individuals in an effort to pinpoint variations that can improve disease diagnosis and treatment. http://www.physorg.com/news160056481.html Medicine & Health Mon, 27 Apr 2009 13:08:36 EST news160056481 A majority of the human population has been exposed to newly discovered KI (KIV), WU (WUV), and Merkel cell (MCV) human polyomaviruses, according to a new study by researchers at the University of Colorado. Published March 27 in the open-access journal PLoS Pathogens, the results, based on antibody measurements in serum samples, also suggest that infection with these viruses occurs early in childhood. http://www.physorg.com/news157353638.html Medicine & Health Fri, 27 Mar 2009 06:25:09 EST news157353638 Deletions, duplications or rearrangements of genomic regions in the human genomes produce differences in gene copy numbers, referred to as copy number variations (CNV). Those variations account for a substantial portion of human genetic diversity, and in a few cases, have been associated with behavioural traits or increased susceptibility to disease. A study published today in the open access journal BMC Genetics, describes a CNV map of the African American genome, and compares frequencies of CNVs between African American and white American/European populations. http://www.physorg.com/news157105146.html Medicine & Health Tue, 24 Mar 2009 09:20:22 EST news157105146 A novel blood test could bring a breakthrough in the battle against the dangerous hepatitis-C virus. This procedure offers a considerably cheaper alternative to the normal commercial tests, whilst maintaining equal sensitivity. So now, for the first time, poorer countries will also have the opportunity to monitor their entire blood banks for the hepatitis C virus using optimum methods. http://www.physorg.com/news153550002.html Medicine & Health Wed, 11 Feb 2009 04:47:12 EST news153550002 Researchers at North Carolina State University and the Centers for Disease Control and Prevention have produced the first link between a species of bacteria most commonly found in sheep and human illness. http://www.physorg.com/news150473724.html Medicine & Health Tue, 06 Jan 2009 14:15:24 EST news150473724
