Strictly speaking, the ‘choked’, i.e., inactivated three viruses (A1, A2, B) in the new vaccine will be the same as before. They are included in the vaccine composition on the recommendation of the World Health Organisation. But the additional substances, however, proposed by the researchers, are what make it possible to make this vaccine in tablet form. What is more, believe the authors, this vaccine will be more efficient than all known equivalents. Not because an injection is replaced with a tablet, but because the authors propose to include a so-called adjuvant into the vaccine composition; put simply – an enhancer for the effect of the vaccine. The scientists are already confident of its effectiveness: A similar, intranasal vaccine which they developed previously (what specialists call nasal drops) with the same adjuvant is already at clinical trial stage. The first volunteers will be testing it in the first clinical trials this autumn.
So, the most important component of this vaccine is Korauban, an original immunostimulant, or a substance that intensifies immunity. Its correct name is a stimulant of immunogenesis, a gamma-interferon inductor. This is a close relative of regular cellulose; the same polysaccharide, only of a slightly different structure. It is produced by ‘specially trained’ microorganisms and it serves to enhance the action of the vaccine.
Korauban, if we are to greatly simplify the matter, calls special cells, which are to eliminate alien elements, to where the decontaminated virus has struck, and it presents the enemy to them. As a result the organism strenuously produces protection – special proteins (antibodies) and cells, both directed to the form of the enemy. What is of especial importance is that, as a result, humans produce so-called local cell immunity, of a long-term and wide-ranging action; not only against the used vaccine and existing epidemic viruses, but also against the pathogens of future epidemics. And in the region of the nose and throat. It is with damage to the latter, incidentally, that the illness begins. In the first days flu usually passes without a cold.

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...
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”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
