Most participants in GAIT study saw little relief
The popular dietary supplements glucosamine and chondroitin sulfate proved no better than a placebo in relieving osteoarthritis knee pain in most participants of a major national trial. But the study, published in the Feb. 23 issue of the New England Journal of Medicine, also showed a smaller subgroup of trial patients with moderate to severe osteoarthritis knee pain taking the combination of the two supplements experienced significant pain relief.
"For the study population as a whole, supplements were found to be ineffective," said rheumatologist Daniel O. Clegg, M.D., professor of medicine at the University of Utah School of Medicine, chief of rheumatology at the George E. Wahlen Veterans Affairs Medical Center in Salt Lake City, and principal investigator for the national trial. "An exploratory analysis suggested, however, that the combination of glucosamine and chondroitin sulfate might be effective in patients who suffer from moderate to severe osteoarthritis knee pain."

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
