These patients were, therefore, reassigned as complete responders, and we found that they did just as well as patients who had been given the 'all clear' from the CT scan."

Fontana says the low levels of TNFa, CRP and TGFb, combined with evidence of "younger" hearts in people on caloric restriction, has led his research team to hypothesize that inflammation may play a key role in the aging pro...Study finds implantable defibrillators as effective in women as in men

Beta blockers in combination with ACE-inhibitors and statins are the treatment of choice for heart attack survivors, but fail to reduce risk o...Women who undergo reconstructive breast implantation frequently develop short-term complications
