A lot of people suffer from herpes for all their lives. The herpes simplex virus (Type 1) constantly inhabits the organism revealing its presence from time to time. Once highly active anti- herpes drugs were developed (acyclovir and phosofonoacetic acids), the virus responded with new forms resistant to theses drugs. The Belorus researchers from the State Scientific Research Institute of Epidemiology and Microbiology, Ministry of Health, Republic of Belorus, and the Institute of Photobiology, National Academy of Sciences of Belorus, have suggested to fight these mutant viruses by the photodynamic inhibition method.
The method is based on the photosensitive reactions, which take place in biological systems. Researchers all over the world are actively developing new methods based on these reactions to cure various diseases. The essence of the method is that photosensitizer substances interact with the sick cells or infection pathogene. The above substances get destroyed under the influence of the visible light and form free radicals, including active forms of oxygen, which easily oxidize proteins, lipids and other biologically important molecules. Photosensitizers are of different types, but the Minsk researchers have chosen merocyanins, which bundle with diverse viral shells including the herpes simplex virus (Type 1).
The experiments were carried out with the cell culture of the kidney of the African green talapoin (Cercopithecus aethiops), infected by the herpes simplex virus (Type 1). Consequences of infection can be noticed already in 4-5 hours: the cells start to divide intensely, they merge with each other, foreign impurities appear in them, besides there are other typical indications perfectly visible through a microscope. Within 48-56 hours, the cells take the shape of a ball, flake away from the walls of a flask where they were grown up and all of them get killed. It was decided to annihilate the infected cells.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
