A consequence of the different cancers of the hepatobiliary system is blocked bile ducts. However, artificial catheters known as "stents" can remediate this problem. Stents are medical implants which reopen narrowed bile ducts to allow the outflow of bile. However, bacteria colonize these catheters forming dense communities, so-called biofilms. Inside these biofilms, bacteria are not only protected from the immune response initiated by the host but also from antibiotics. http://www.physorg.com/news161257134.html Biology Mon, 11 May 2009 10:42:06 EST news161257134 Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants. http://www.physorg.com/news142763924.html Nanotechnology Thu, 09 Oct 2008 09:38:44 EST news142763924
