Findings could help with design of combination products that are not compromised by adverse host responses
Medical devices are traditionally thought of as fairly simple implants such as stents and hip replacements - pieces of plastic or metal that are placed in the body to handle a very specific function. But biomedical devices now on the drawing board are considerably more sophisticated and represent an unprecedented melding of man and machine.
Combination products, devices that include a combination of drug, biological and device components, are expected to be the next big thing in biomedical devices. An example of a combination product is a tissue-engineered device that combines living cells with a polymer scaffold. When implanted into a patient, the device can replace or restore damaged tissue or organ function. While the response of the body to each component is well known, considerably less is known about how their new union may affect the body’s reaction to a combination device.

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...
In the fight against cancer, scientists are developing new drugs to hit tumor cells at so far unused weak points. Such a “sore spot” is the protein complex...
In an article that appears in the journal “Review of Modern Physics”, researchers at the Laboratory for Attosecond Physics (LAP) assess the current state of the field of ultrafast physics and consider its implications for future technologies.
Physicists can now control light in both time and space with hitherto unimagined precision. This is particularly true for the ability to generate ultrashort...
