A functioning liver is essential for human survival with liver failure ultimately resulting in death, and liver transplantation is presently the only treatment for acute and chronic liver failure. However, the supply of donor livers is insufficient to meet demand, and in the United Kingdom, 20% of patients waiting for a liver transplant will die from liver failure before a suitable donated organ becomes available.
Head of the group Dr James Ross said: "Potentially, cell replacement therapies could provide alternative treatments that would avoid difficulties associated with obtaining sufficient donor organ transplantation. We have now identified primitive cells with the potential to mature into different cell types within and out with the liver. It is possible that these cells lie dormant in the adult liver and may be the source of repair cells that are activated by severe liver injury."
"The liver is often able to repair and heal itself following injury or damage and this occurs in one of three ways. Firstly, mature liver cells have a well recognised and extensive capacity to divide in response to injury. Secondly, in response to massive loss of functioning liver tissue, a population of primitive liver stem cells may be stimulated to proliferate and develop into mature liver cells. The third mechanism of liver repair involves circulating stem cells originating from other sources, such as the bone marrow, and it is possible that these cells may be recruited into the liver and form new liver cells."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
