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."

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
