The use of genome-wide analysis (GWA), where the entirety of an individual's DNA is examined to look for the genomic mutations or variants which can cause health problems is a massively useful technology for diagnosing disease. However, it can also pose major ethical problems if used incorrectly, say new recommendations from the European Society of Human Genetics (ESHG) published on line today (16 May 2013) in the European Journal of Human Genetics. http://medicalxpress.com/news/2013-05-experts-urge-caution-genetic-sequencing.html Genetics Thu, 16 May 2013 10:32:46 EST news287919140 Researchers at the University of Twente's MIRA research institute have developed a system which may drastically reduce the use of laboratory animals in science. The system, which is designed to be implanted in laboratory animals, contains a series of tiny "compartments". A single specific condition can be investigated in each separate compartment, so the system can significantly reduce the number of laboratory animals needed for a study. Details of the study in which these scientists first demonstrated the use of this system are being published today in the scientific journal Integrative Biology. The system is being marketed by Screvo, a University of Twente spin-off company. http://medicalxpress.com/news/2013-05-case-laboratory-animals.html Other Thu, 16 May 2013 08:25:57 EST news287911548 Today, at the start of the "Tick Week", the National Institute for Public Health and the Environment (RIVM) and Wageningen University are commencing a large-scale study to discover whether preventive use of antibiotics can stop Lyme disease developing after a tick bite. Of the more than 3400 ticks that were sent to RIVM via Tekenradar.nl (Tick radar) last year, more than 20% turned out to be infected with the Borrelia bacteria which can cause Lyme disease. Around 3% of the people bitten by ticks developed Lyme disease. http://medicalxpress.com/news/2013-04-large-scale-antibiotic-usage-lyme-disease.html Diseases, Conditions, Syndromes Tue, 16 Apr 2013 09:13:46 EST news285322416 (HealthDay)—Older women diagnosed with breast cancer years after their last mammogram, and those who never had a mammogram, have an increased risk of dying from their cancer, a new study suggests. http://medicalxpress.com/news/2013-04-older-women-mammograms-tied-worse.html Cancer Mon, 08 Apr 2013 10:00:01 EST news284631814 Scientists have characterized how the functionality of genetically engineered T cells administered therapeutically to patients with melanoma changed over time.
