Muscle Wasting Caused By Aging And Heart Failure Can Be Slowed By Exercise published
Tue, 08 May 2012 02:00:00 PDT
Exercise can counteract muscle breakdown, increase strength and reduce inflammation caused by aging and heart failure, according to new research in Circulation, an American Heart Association journal. The benefits for heart failure patients are similar to those for anyone who exercises: there's less muscle-wasting, and their bodies become conditioned to handle more exercise...
Problems In Transport Of Donated Human Retina Led Researchers To Discover New Treatment Path For Eye Disease published
Tue, 08 May 2012 00:00:00 PDT
Sloppy shipping of a donated human retina to an Indiana University researcher studying a leading cause of vision loss has inadvertently helped uncover a previously undetected mechanism causing the disease. The discovery has led researchers to urge review of how millions of dollars are spent investigating the cause of a type of age-related macular degeneration called choroidal neovascularization...
First Oral Agent To Quell Invasive Macular Degeneration, Restore Lost Vision published
Mon, 07 May 2012 01:00:00 PDT
There may be new found hope for patients whose vision is threatened when medicine injected directly into the eyes fails to cause abnormal blood vessels to recede. While injectable drugs called angiogenesis (an-gee-oh-jen-esis) inhibitors are considered a modern miracle and have become the standard of care for patients with the fast-progressive form of macular degeneration, they are not foolproof...
