Whether a painless, portable device that uses electrical current rather than X-ray to look for breast cancer could be an alternative to traditional mammograms is under study at the Medical College of Georgia.
MCG is one of 20 centers internationally studying new technology developed by Z-Tech Inc., to compare traditional mammograms to impedence scanning, a technique based on evidence that electrical current passes through cancerous tissue differently than through normal tissue.

A blue curing light used to harden dental fillings also may stunt tumor growth, Medical College of Georgia researchers say.
"The light sends wavelengths of blue-violet light to the composite, which triggers hardening," says Alpesh Patel, a rising MCG School of Dentistry junior. "The light waves produce free radicals that activate the catalyst and speed up polymerization of the composite resin. In oral cancer cells, though, those radicals cause damage that decreases cell growth and increases cell death."

When a mouse's immune system is deciding whether to reject a skin graft, one powerful member of a molecular family designed to provoke such a response can effectively reduce the visibility of the mouse's own cells and help the graft survive, researchers say. "This is a molecule with huge potential to regulate immune response," Dr. Anatolij Horuzsko, reproductive immunologist at the Medical College of Georgia Center for Molecular Chaperone/Radiobiology and Cancer Virology, says of HLA-G dimer.
