Coaxing a patient's own cells to hunt down and tackle infected or diseased cells is a promising therapeutic approach for many disorders. But until now, efforts to follow these specially modified cells after their reintroduction to the body have relied on short-term monitoring techniques that don't give a complete picture of the cells' status. http://www.physorg.com/news146219840.html Medicine & Health Tue, 18 Nov 2008 08:37:20 EST news146219840 Scientists have developed a new imaging agent that can be used in scanning for tumours, and which gives a much clearer and more precise image than existing methods. The discovery has the potential to revolutionise pre-clinical cancer research and clinical diagnostic practice, and it makes use of compounds that have already been approved for treating patients: the anti-cancer drug bevacizumab (Avastin) and Copper-64, a radioactive copper nuclide, which is approved by the US Food and Drug Administration (FDA) for some clinical trials. http://www.physorg.com/news143893016.html Medicine & Health Wed, 22 Oct 2008 11:16:56 EST news143893016
