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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
