Autoantibodies (autoAB) against the insulin receptor (IR) are known to cause a rare form of diabetes, i.e. insulin resistance type B. AutoAB against the structurally and functionally related receptor for insulin-like growth factor-1 (IGF1R) have only recently been described and are implicated in autoimmune diseases. However, the prevalence and clinical importance of these autoAB are not yet fully understood as respective sensitive and non-radioactive test systems for routine use were missing. A reliable assay system for the detection and quantification of these autoAB should be met with highest interest by basic researchers and clinicians alike, especially in the fields of diabetes, growth and cancer research, given the central importance of the insulin and IGF1 hormone axes for controlling growth, glucose metabolism and cell proliferation in humans.<br><br> <strong>Technology</strong><br> Two novel non-radioactive and highly sensitive immunoassays for detection and quantification of autoAB against the IR and IGF1R have been developed. For reasons of sensitivity, specificity and automation, the bridge technology has been chosen as most suitable assay format (see scheme). Using these novel in vitro diagnostica, autoAB against the IR and the IGF1R are detected with an astonishing 10% prevalence in the adult population. Notably, a high proportion of cross-reacting autoAB are found, reacting with similar strength to both the IR and IGF1R. The clinical and diagnostic importance of these results remains to be established in ongoing studies.<br><br>

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

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...
