Study shows effectiveness of doxycycline in slowing disease progression
A tetracycline antibiotic, doxycycline, has been successfully used to treat a wide-range of bacterial infections. In addition to its effects as an antibiotic, doxycycline has other actions as a drug and, in laboratory studies with animals and with human tissue, can inhibit the degradation of cartilage in a way that could be useful for the treatment of osteoarthritis (OA). OA is a common form of arthritis associated with pain and disability related to the breakdown of cartilage, the tissue in the joint that absorbs shock and promotes smooth movement.
On the strength of preclinical evidence, a team of rheumatologists affiliated with six clinical research centers across the United States conducted the first long-term clinical trial to determine the benefits of doxycycline in the treatment of OA--particularly, OA of the knee. Their findings, featured in the July 2005 issue of Arthritis & Rheumatism (http://www.interscience.wiley.com/journal/arthritis), suggest that doxycycline may slow the progression of joint damage and point to the need for further research into the drugs effect on the signs and symptoms of this disease.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
