BGI, the world's largest genomics organization, reported that it can use next-generation sequencing to analyze DNA as low as 200 ng from formalin-fixed paraffin-embedded (FFPE) samples. This advancement enables researchers to easily identify the genetic details and pathology mechanism of FFPE disease samples, especially for some rare tumors, with higher accuracy and reliability than existing techniques. http://medicalxpress.com/news/2012-03-bgi-next-gen-sequencing-analysis-ffpe.html Genetics Thu, 08 Mar 2012 10:52:41 EST news250426351 High-throughput DNA sequencing technologies are leading to a revolution in how clinicians diagnose and treat cancer. The molecular profiles of individual tumors are beginning to be used in the design of chemotherapeutic programs optimized for the treatment of individual patients. The real revolution, however, is coming with the emerging capability to inexpensively and accurately sequence the entire genome of cancers, allowing for the identification of specific mutations responsible for the disease in individual patients. http://medicalxpress.com/news/2012-02-georgia-tech-algorithm-cancer-treatments.html Cancer Mon, 13 Feb 2012 14:57:36 EST news248367450 A new way to fight inflammation uses molecules called polymers to mop up the debris of damaged cells before the immune system becomes abnormally active, researchers at Duke University Medical Center report. http://medicalxpress.com/news/2011-08-anti-inflammatory-agents-silence-overactive-immune.html Inflammatory disorders Mon, 15 Aug 2011 15:01:02 EST news232637347 Researchers at Case Western Reserve University School of Medicine have discovered a long-sought cellular factor that works to inhibit HIV infection of myeloid cells, a subset of white blood cells that display antigens and hence are important for the body's immune response against viruses and other pathogens. http://medicalxpress.com/news/2011-06-hiv-inhibiting-mechanism.html HIV & AIDS Wed, 29 Jun 2011 13:02:19 EST news228571316 Double-stranded (ds) RNA viruses are a diverse group of viruses that include rotaviruses, a common cause of gastroenteritis. The ability of the immune system to detect and destroy viruses is critical for human health and survival. Now, a study published by Cell Press in the June 23rd issue of the journal Immunity identifies a novel sensor that is necessary to activate the immune response to viral infection. The research enhances our understanding of the complex and overlapping mechanisms our immune cells use to thwart infection. http://medicalxpress.com/news/2011-06-complex-viral-infection.html Medical research Thu, 23 Jun 2011 13:28:52 EST news228054521 (Medical Xpress) -- Northwestern University chemists have synthesized a new form of DNA, one that can begin to be used to create new gene regulation therapies, for the prevention or treatment of diseases such as cancer. http://medicalxpress.com/news/2011-06-dna.html Cancer Fri, 03 Jun 2011 05:52:32 EST news226299140 A person's blood reveals whether he or she has lung cancer: this has been demonstrated by researchers at the University of Bonn. In collaboration with colleagues at the Cologne University Hospital, they are developing a blood test for smokers which could save human lives in the future, since the earlier a lung tumor is detected, the better the chances of survival are. The study has just been published in the journal Clinical Cancer Research. http://medicalxpress.com/news/2011-05-lung-cancer-early.html Cancer Mon, 16 May 2011 09:53:17 EST news224758297
