New research from the University of North Carolina at Chapel Hill indicates that treatment with anabolic steroids may improve surgical repair of massive or recurrent tears of the shoulder’s rotator cuff tendons. Such injuries extend well beyond the world of high-performance athletes, professional and collegiate – often occurring among older weekend athletes, including tennis and golf players. The study, which appears in the June issue of the American Journal of Sports Medicine, was led by Dr. Spero Karas, assistant professor of orthopedic surgery in UNC’s School of Medicine.
Dr. Albert J. Banes, professor of orthopedics and biomedical engineering at UNC, developed a bioengineered tendon that figured prominently in the study’s experiments. Through a company he founded 18 years ago, Banes developed a special tissue plate in which cells in a liquid collagen gel could remodel on their own to form a tissue-like matrix or structure. The structure then could be placed under mechanical load by a computer-driven pressure-controlled system.
In 2002, his laboratory announced it had successfully bioengineered a rhythmically beating experimental model of heart muscle. Anabolic steroids benefit millions of people a year, said Karas, including those with deficiencies in sex hormones and burn victims who need to build up their metabolism to repair musculoskeletal tissue. They also are FDA-approved for treating anemia for their ability to help the body rebuild blood.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

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...
