University of California, San Diego researchers have proven in animal studies that fibrosis in the liver can be not only stopped, but reversed. Their discovery, to be published in PLoS Online on December 26, opens the door to treating and curing conditions that lead to excessive tissue scarring such as viral hepatitis, fatty liver disease, cirrhosis, pulmonary fibrosis, scleroderma and burns.
St Andrews scientists have discovered a new way of levitating tiny objects – paving the way for future applications in nanotechnology.
A pilot study of the first proposed major change in decades to cardiopulmonary resuscitation (CPR) suggests that performing the maneuver while patients are on their stomachs offers far better restoration of blood flow and blood pressure than the standard practice of keeping patients on their backs. The feasibility study of so-called reverse CPR, conducted by researchers at Johns Hopkins and Columbia universities, appears in the June issue of the journal Resuscitation. CPR in the prone position was tested at Columbia Presbyterian Medical Center on six critically ill patients already in intensive care units whose hearts had stopped, and who had failed to respond to standard CPR for at least a half-hour.
