Recoverying from third and fourth degree burns, the most damaging types, is a slow and painful process that inevitably leaves excessive scar tissue. Russian researchers have developed a pharmacological enzyme preparation to accelerate the debridement process and wound healing, which reduces the preparation time for grafting and diminishes scarring.
Their product, called ENZYCOL, is a mixture of collagenases from the Kamchatka crab that rapidly dissolves the dense collagen matrix of necrotic skin forming after a burn. By removing this non-living tissue, ENZYCOL promotes the healing of the surrounding healthy tissue, a vital process for preventing the onset of infection. The debridement period for burns pre-treated with the crab collagenase mixture is 2 days shorter than with traditional enzyme therapies such as trypsin.
The research team consisted of scientists from the Russian Cardiology Research Center in Moscow and the Research Center of Toxicology and Hygienic Regulation of Biopreparations in Serpukhov (Moscow Region). Seventy-one scientists and technical staff, of which forty represented former biological and chemical weapons experts, participated in two ISTC projects to develop this technology. They began their work in 1999 to develop the powder preparation and confirm its safety and effectiveness in vitro. In the follow-up project, which began in 2002 and is currently going on, the scientists modified the method for preparing ENZYCOL to make it suitable for pilot scale production. They also performed pre-clinical trials on laboratory animals, which proved that the enzyme cocktail is non-toxic, non-mutagenic, and non-irritating on skin.

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...
