A team of researchers from UCLA and the University of Michigan has developed a material that could help prevent blood clots associated with catheters, heart valves, vascular grafts and other implanted biomedical devices.
Blood clots at or near implanted devices are thought to occur when the flow of nitric oxide, a naturally occurring clot-preventing agent generated in the blood vessels, is cut off. When this occurs, the devices can fail. (more…)
The latest results from an expedition to Mount Everest that looked at the body’s response to low oxygen levels suggest that drugs or procedures that promote the body’s production of a chemical compound called nitric oxide (NO) could improve the recovery of critically ill patients in intensive care.
Many critically ill patients suffer from a shortage of oxygen (a condition known as ‘hypoxia’), which can be life-threatening. NO is produced by virtually every cell and organ in the body where it serves many important functions including the regulation of blood pressure, learning and memory formation, and protecting us from infectious diseases.
