A group of studies published in the January 24 issue of Archives of Internal Medicine add to the growing body of medical literature about the cardiovascular risks that may be associated with the class of pain-relieving drugs known as COX-2 inhibitors. Archives of Internal Medicine is one of the JAMA/Archives journals.
The Celecoxib Rofecoxib Efficacy and Safety in Comorbodities Evaluation Trial (CRESCENT) evaluated the effects of the COX-2 inhibitors and naproxen on 24-hour blood pressure readings in patients with type 2 diabetes, hypertension, and osteoarthritis. Patients were randomly assigned to receive 200 mg of celecoxib (Celebrex; Pfizer Inc., New York) [n= 136], or 25 mg of rofecoxib once daily (Vioxx, Merck & Co., West Point, Penn.) [n = 138], or 500 mg of naproxen twice daily (Naprosyn; Roche Pharmaceuticals, Basel, Switzerland) [n = 130] for 12 weeks. A total of 65 centers from 7 countries participated in this trial from May 2001 to April 2002. Patient evaluations were conducted at the start of the study and 1, 2, 6, and 12 weeks after randomization.
"Reductions in osteoarthritis symptoms, including pain, mobility, and stiffness, were similar in all treatment groups," the researchers found. "The mean (average) 24-hour systolic [top number in blood pressure reading] blood pressure following 6-weeks of therapy was increased significantly by refecoxib but not by celecoxib or naproxen."

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
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...
