chronic disease

Like a chronic disease wasting a body, ocean "dead zones" with too little oxygen for marine life are spreading around the globe, researchers reported Thursday.

A new research study aims to stop the progression of early active stage multiple sclerosis in its tracks.

There are currently more than 2.5 million people worldwide with MS, a chronic disease that affects the central nervous system.

Genes that scientist believe are turned off are actually functioning at a low level that has previously been undetected, a discovery that could help answer questions about chronic disease and aging.

Of the about 25,000 human genes science has identified, half are believed to be silent at any particular time and activated only when needed.

But a biomedical and computer expert has discovered that current tools cannot measure extraordinarily low levels of gene expression signals.

An international research study, published in The Lancet, has thrown into question the current method of treating Crohn's disease -- opening the door to a safer and more effective treatment option for sufferers of the chronic disease.
