In an NIH-funded clinical trial, led at Saint Louis University by professor of ophthalmology Sophia Chung, M.D., researchers aim to bring sight back to those who have lost vision due to idiopathic intracranial hypertension. [More]
Researchers identify possible way to prevent headaches of climbers

Researchers identify possible way to prevent headaches of climbers

By monitoring blood flow in the brains of six climbers scaling Mount Kilimanjaro in Tanzania, German medical researchers have identified a possible way to prevent the headaches that are a common feature of altitude sickness. This work appears in the latest issue of JNIRS—Journal of Near Infrared Spectroscopy. [More]

Ibuprofen may be used effectively for altitude sickness: Study

Ibuprofen may be used effectively for altitude sickness: Study

Altitude sickness manifests by symptoms including a headache, fatigue, dizziness and sometimes nausea and vomiting. In addition, patients most likely also feel like they are working harder to breathe, like they are constantly trying to catch their breath. It normally takes days to weeks to fully acclimate to a higher altitude. It affects between 25 percent and 40 percent of the population and can be debilitating. [More]

Trekkers and climbers face high risk for Acute Mountain Sickness

Trekkers and climbers face high risk for Acute Mountain Sickness

Climbers of high peaks such as Mount Kilimanjaro are at high risk for Acute Mountain Sickness (AMS). Trekkers should not ignore AMS warning signs, which can progress to more serious medical outcomes. [More]
Researchers create artificial RNA inhibitor to block excess blood cells formation

Researchers create artificial RNA inhibitor to block excess blood cells formation

Researchers at UT Southwestern Medical Center have uncovered a key step in the creation of new red blood cells in an animal study.They found that a tiny fragment of ribonucleic acid (RNA), a chemical cousin of DNA, prompts stem cells to mature into red blood cells. The researchers also created an artificial RNA inhibitor to block this process. [More]
