Arthritis can be treated with nonsteroidal anti-inflammatory drugs (NSAIDs) but the incidence of gastrointestinal problems is significant, resulting in approximately 103,000 hospitalizations and 16,500 deaths per year in the United States. The alternative COX-2 inhibitors may reduce these adverse events, but some have been withdrawn from the market due to cardiovascular complications and other adverse effects. Several questions remain about the safety advantage of COX-2 inhibitors compared with nonspecific NSAIDs.
In a report in the March 2006 issue of The American Journal of Medicine, researchers from eight university and hospital health centers and Pfizer Inc present the results of a large, multinational, “real-world,” controlled clinical trial in patients with osteoarthritis. Over 13,000 patients from 39 countries in six continents were randomly assigned for treatment with either celecoxib 100 mg twice daily (BID), celecoxib 200 mg BID, or nonselective NSAID therapy (diclofenac 50 mg BID or naproxen 500 mg BID) for 12 weeks.
Each patient was seen three times during the study and the efficacy of their treatment was assessed by three separate means. Any possible serious upper gastrointestinal adverse event had to be investigated by two independent committees (both blinded to patient randomization), using two different methodologies and definitions.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
