New MS Treatment is Promising in Mice

October 10, 2013 11:53 am | News | Comments

Scientists have identified a set of compounds that may be used to treat MS in a new way: by boosting a population of progenitor cells that can in turn repair MS-damaged nerve fibers.                   


Drug Can Target Deadly Breast Cancer

October 4, 2013 1:40 pm | News | Comments

Often deadly “triple-negative” breast cancers might be effectively treated in many cases with a drug that targets a previously unknown vulnerability in the tumors, according to a new study.  Researchers found blocking cystine from entering triple-negative breast cancer cells can significantly inhibited their growth in culture and when the cancer cells were transplanted into mice.

Pills Made from Poop Cure Serious Gut Infections

October 3, 2013 12:01 pm | by BY MARILYNN MARCHIONE - AP CHIEF MEDICAL WRITER | News | Comments

Hold your nose and don't spit out your coffee: Doctors have found a way to put healthy people's poop into pills that can cure serious gut infections - a less yucky way to do "fecal transplants." Canadian researchers tried this on 27 patients and cured them all after strong antibiotics failed to help.
