High-Altitude Cerebral Edema Likely Caused By Leaks In Blood-Brain Barrier
PHILADELPHIA, Penn. -- The latest high-tech gear can't protect climbers on Mount Everest from one of the hazards feared most by those who spend time at extreme heights -- oxygen deprivation, or hypoxia, resulting in the potentially lethal brain swelling known as high-altitude cerebral edema. ...USGS reports continued decline of California sea otters
