A new target-seeking affibody molecule can be used to visualize cancer tumors and to treat them. This has been shown in a dissertation by Ann-Charlott Steffen to be publicly defended at Uppsala University on April 22.
The gamma camera image shows the distribution of radioactivity in a mouse given target-seeking affibody molecules marked with radioactivity. The uptake can be seen in the thyroid gland, the kidneys, and the tumor.
Every third Swede is estimated to receive a cancer diagnosis sometime in their lives, and nearly one Swede in four dies as a result of the disease. The need for improved detection and treatment of the disease is great.
Existing treatments include surgery, chemotherapy, and radiation. Surgery is most effective for large, well-defined tumors, but if the disease has spread, chemotherapy and/or radiation are needed. These forms of treatment affect all dividing cells, leading to toxic effects on healthy tissue. This toxicity limits the size of the dose that can be given, thereby also limiting the probability that the disease will be cured. By seeking out tumor cells and selectively delivering cytostatics or radiation to the cancer cells, the dose affecting healthy tissue can be reduced and the dose to the tumor can be increased. This improves the chances of curing the disease.

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...
