2. PET and bioluminescent imaging aid evaluation of stem cells' potential for new ways to treat disease
   12-06-2007 · EurekAlert!
   Using positron emission tomography imaging with bioluminescence -- the light produced by a chemical reaction within an organism -- researchers are starting to understand the behavior of transplanted or implanted stem cells that may one day be used to develop new treatments for disease.

3. Stroke victims may benefit from stem cell transplants
   01-28-2008 · EurekAlert!
   Two studies published in the current issue of Cell Transplantation examine the potential for cell transplants to benefit stroke victims. When injected into animal models and tracked via chemical tags and imaging, mensenchymal stem cells in one study, and bone marrow stromal cells in a second study, migrated within one to two weeks to affected brain areas and became therapeutically active. Both studies suggest that novel stem cell therapies can be developed.

8. Consumers neutral on risks, benefits of nano
   12-05-2006 · EurekAlert!
   The largest, most comprehensive survey of public perceptions of nanotechnology products finds US consumers are willing to use specific nano-containing products -- even if there are health and safety risks -- when the potential benefits are high. The study also finds US consumers rate nanotechnology as less risky than everyday technologies like herbicides, chemical disinfectants, handguns and food preservatives. The findings appear in December's issue of Nature Nanotechnology.

9. New inhibitor has potential as cancer drug
   10-22-2007 · EurekAlert!
   Laboratory experiments have previously shown that cancer cells overproduce an enzyme, heparanase, which splits the body's own polysaccharide heparan sulfate into shorter fragments. The amount of enzyme is related to the degree of malignancy. Today a study is being published in the journal Nature Chemical Biology in which Uppsala University researchers show, on the basis of animal models, that an inhibitor for heparanase would be extremely interesting as a drug candidate.

10. Environmental epigenetics has potential for preventing and treating disease
    01-31-2008 · EurekAlert!
    New research on environmental influences on health and disease has begun to shed light on why genetically identical individuals demonstrate different characteristics, such as susceptibility to disease. Scientists have found that environmental exposure to nutritional, chemical and physical factors can alter the epigenome. Literally meaning "above the genome," the epigenome refers to differences in gene expression that are inherited without changing the sequence of DNA.
