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.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
