A good response to the SARS-CoV-2 vaccination is based on naive immune cells, whereas pre-existing memory cells are rather disadvantageous
People who have often been infected by common cold viruses – which also belong to the coronaviruses – are not better protected against COVID-19, neither after infection with SARS-CoV-2 nor after vaccination. "We already showed in 2020 that earlier exposure to common cold viruses does not provide ...
A new method reliably detects protein changes in blood that are typical of Parkinson's disease: "The results are really sensational"
Until now, the diagnosis of Parkinson's disease has been based primarily on typical movement disorders such as muscle stiffness, slower movements and shaking. However, the disease starts up to twenty years before it becomes noticeable as a result of these symptoms. To date, there have been ...
Bacterial dynamin protein is involved in a previously unknown protective mechanism against bacteriophage infections
Bacteria as unicellular organisms are attacked by specialised viruses, the so-called bacteriophages or phages for short. To defend themselves against phage infections, bacteria feature a multi-stage protective mechanism, which in principle consists of components of an innate and an acquired ...
Research teams use imaging and modelling to explain why single bacterial cells do not always grow exponentially
Bacteria as unicellular organisms reproduce by dividing their entire organism. In this way, they can multiply particularly quickly, which allows the exponential growth of bacterial populations, also known from pathogens. The population growth is based on the growth of the individual bacterial ...
Ecologists identify a new rule on how bacterial communities form
The fact that different bacterial strains interact with each other and exchange substances is essential, for example, for the production of yogurt or in maintaining our healthy intestinal flora. But how do bacteria choose their interaction partners? The research group of ecologist Prof. Dr. ...
Researchers succeed for the first time in demonstrating that changes in certain proteins involved in packaging of the genetic material have a causal effect on the frequency of mutations
The change of genetic information over time is a key factor for evolutionary adaptations with which living beings can adapt to changes in their environment. On the one hand, genetic variability arises in the course of reproduction, where genetic information is divided and recombined in the ...
An international collaboration uncovers several genetic markers associated with SARS-CoV-2 infection or COVID-19 severity
In March of 2020, thousands of scientists around the world united to answer a pressing and complex question: what genetic factors influence why some COVID-19 patients develop severe, life-threatening disease requiring hospitalization, while others escape with mild symptoms or none at all? A ...
How to obtain a palladium catalyst for the selective hydrogenation of acrolein
Chemical reactions don’t always go to plan. Unwanted by-products lead to extra costs and waste resources. Selective catalysts can help, but chemists have to test out large numbers before they find the right fit. Researchers have now investigated, on an atomic level, how to obtain a palladium ...
Highest resolution insights into living cells
Bacteria as unicellular organisms normally reproduce by binary cell division, i.e. the duplication of the entire organism consisting of a single cell. This allows particularly rapid multiplication, such as the exponential growth known from pathogens, and requires the separation and distribution ...
Research team has identified cell types in the blood that indicate severe disease progression in COVID-19
In severe cases of COVID-19 disease, not only classic immune cells play a role. In particular, the release of immature precursor cells from the bone marrow into the blood indicates a particularly severe course of the disease and could contribute to complications. This has been shown by an ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
