New research published online in the FASEB Journal suggests that a specific enzyme, called 5-lipoxygenase, plays a key role in cell death induced by microgravity environments, and that inhibiting this enzyme will likely help prevent or lessen the severity of immune problems in astronauts caused by spaceflight. Additionally, since space conditions initiate health problems that mimic the aging process on Earth, this discovery may also lead to therapeutics that extend lives by bolstering the immune systems of the elderly. http://medicalxpress.com/news/2012-04-scientists-enzyme-aging-astronauts-.html Genetics Mon, 30 Apr 2012 11:30:02 EST news255003825 (Medical Xpress) -- In parts of the world without reliable electricity, a pedal-powered nebulizer could provide life-saving asthma treatments.
