Natural substance in red wine binds with the KSRP regulator protein and provides for its activation
A natural substance present in red wine, resveratrol, inhibits the formation of inflammatory factors that trigger cardiovascular diseases.
This has been established by a research team at the Department of Pharmacology of the University Medical Center of Johannes Gutenberg University of Mainz (JGU) working in collaboration with researchers of the Friedrich Schiller University in Jena and the University of Vienna. Their results have recently been published in the scientific journal Nucleic Acids Research.
Despite the fact that they eat more fatty foods, the French tend to less frequently develop cardiac diseases than Germans. This so-called French Paradox is attributed to the higher consumption of red wine in France and it has already been the subject of various studies in the past. A number of research projects have actually demonstrated that the natural product resveratrol, present in red wine, has a protective effect against cardiovascular diseases. But what exactly is the reason for this?
It seems that at least part of the protective effect can be explained by the fact that resveratrol inhibits the formation of inflammatory factors, a conclusion reached by the research team of Junior Professor Andrea Pautz and Professor Hartmut Kleinert of the Mainz University Medical Center following collaboration in a joint project with Professor Oliver Werz of the Friedrich Schiller University in Jena and Professor Verena Dirsch of the University of Vienna.
In fact, the researchers discovered that the natural substance binds to the regulator protein KSRP and activates it. KSRP reduces the stability of messenger RNA (mRNA) in connection with a number of inflammatory mediators and thus inhibits their synthesis.
"We now know more precisely how resveratrol inhibits the formation of the inflammatory factors that trigger cardiovascular diseases. This is an important finding in view of the fact that more recent research has shown that cardiovascular diseases are significantly promoted by inflammatory processes in the body," said Pautz.
Cardiovascular disorders, such as myocardial infarction and strokes, frequently occur in association with chronic inflammatory diseases, such as arthritis. The natural substance resveratrol thus has major therapeutic potential, particularly when it comes to the treatment of inflammatory diseases that can cause serious damage to the cardiovascular system.

Researchers see great therapeutic potential in the natural substance resveratrol, particularly in connection with prevention of the synthesis of inflammatory factors in cardiovascular diseases.

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...

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...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
