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 from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
