Receiving a standard 12-lead electro-cardiogram (ECG) is a well established method to get information of the heart's electrical activity recorded from electrodes on the body surface. In comparison to standard ECG, Body-Surface-Potential-Mapping (BSPM) is an advanced method providing more extensive and precise diagnostic data. The reason for an improved detection and separation of pathophysiological heart function by BSPM is due to the much larger number of sampling positions of the electrodes attached to the thorax. Hence, spatially and temporally important features may be captured by BSPM but not by the 12-lead-ECG. So far, high cost and complexity have presented widespread use of BSPM in clinical settings.<br> Our new method requires only a standard 12-lead ECG device with digital data output providing almost identical results as BSPM. The only real differ-ence is that not all channels are being read out simultaneously, i.e. the map-ping is reconstructed from sequentially obtained ECG-Signals. A specific digital signal processing has been developed to synchronize sequentially recorded ECG signals. The resulting data is thus competitive to the “true” parallel BSPM. </p> <b>Benefits:</b>

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.

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...
