A research team from Hungary investigated the probability of disease behavior changes in a well-characterized Crohn's disease cohort with strict clinical follow-up. They found that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients. http://www.physorg.com/news169120957.html Medicine & Health Mon, 10 Aug 2009 15:10:02 EST news169120957 Researchers at the University of Texas Medical Branch at Galveston have discovered two biochemical pathways that the Ebola virus relies on to infect cells. Using substances that block the activation of those pathways, they've prevented Ebola infection in cell culture experiments - potentially providing a critical early step in developing the first successful therapy for the deadly virus. http://www.physorg.com/news164997495.html Medicine & Health Tue, 23 Jun 2009 17:39:10 EST news164997495 Small synthetic fragments of genetic material called small interfering RNA (siRNA) can block production of abnormal proteins; however, these exciting new drug candidates can also induce a strong immune response, causing toxic side effects. Understanding how siRNA stimulates this undesirable immune activity, how to test for it, and how to design siRNA drugs to avoid it are critical topics explored in a timely review article published online ahead of print in Oligonucleotides, a peer-reviewed journal published by Mary Ann Liebert. http://www.physorg.com/news162041263.html Medicine & Health Wed, 20 May 2009 12:28:11 EST news162041263 (PhysOrg.com) -- Diagnosis and treatment in one go: Korean researchers led by Tae Gwan Park and Jinwoo Cheon have developed the basis for a four-in-one agent that can detect, target, and disable tumor cells while also making them macroscopically and microscopically visible. http://www.physorg.com/news160820306.html Chemistry Wed, 06 May 2009 09:19:25 EST news160820306 Yale researchers describe a breakthrough in safe and effective administration of potential antiviral drugs - small interfering RNA (siRNA) molecules that silence genes - the first step in development of a new kind of treatment for sexually transmitted diseases (STDs).
