Researchers from Finland have found that the antidepressant drug fluvoxamine (brand names Fevarin, Faverin, Luvox etc.) drastically increases the concentrations of tizanidine (Sirdalud, Zanaflex) in blood.
Concomitant use of fluvoxamine and tizanidine results in severe and prolonged decrease in blood pressure and greatly enhanced central nervous system effects. This previously unrecognised interaction can be dangerous, particularly in elderly patients, and the concomitant use of the two agents must be avoided. Both fluvoxamine and tizanidine have been in wide clinical use for more than 10 years.
The concentrations of tizanidine in blood were increased on average 33-fold by fluvoxamine in a carefully controlled study in healthy volunteer subjects. The volunteers ingested the usual 100-mg dose of fluvoxamine or placebo daily for 4 days, and then a single 4-mg dose of tizanidine. The interaction was observed in each of the ten subjects; the smallest increase in tizanidine concentration by fluvoxamine was 14-fold, the greatest increase was 103-fold!

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...
