The survival rate for mice treated with each of the compounds tested in the combination therapy was two-fold over mice treated with Ciprofloxacin alone. "This represents a significant advance in developing a possible emergency treatment for anthrax," said Dr. Pe...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels
