Liver cancer affects over 2,800 people in the UK each year, of which nearly 2,700 die, according to Cancer Research UK. Surgery is the best option, but is unsuitable for most patients, and liver tumours are very resistant to chemotherapy.
Studies in mice by Zhi Yuan and his team at Nankai University, China, revealed that the liquorice compounds, glycerrhetinic acid and glycerrhizic acid, preferentially accumulate in the liver. And when attached to anti-tumours drugs, they are more effective tissue-specific drug carriers than the traditionally used antibodies and oligopeptides (Polymer International DOI 10.1002/pi.2051). ‘Our primary results show that they are effective as liver targeting carriers,’ says Yuan. Clinical trials are planned for the near future. In addition, glycerrhizic acid is tens of thousands of times cheaper and easier to isolate than the antibodies usually used.
Tim Meyer, Consultant Medical Oncologist at the Royal Free Hospital London agrees, that tissue-specific drugs could potentially provide more effective treatment, because a higher concentration of the drug is delivered to the tumour. This would reduce the dose required and significantly decrease toxic effects on other parts of the body.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
