Tsukuba, Japan - Dermatomyositis is an idiopathic inflammatory myopathy that has been regarded as an autoimmunity-based disorder, although its pathogenesis remains unclear. In this study, researchers from the University of Tsukuba used a mouse model to identify a mechanism by which dermatomyositis may develop in humans. The animal model and findings can be used to better understand the disease and develop disease-specific treatments.
The landscape of sloping vineyards on the banks of the River Mosel in Germany is a characteristic symbol of a region, which cannot be understood without its wine: the Mosel wine region. Tourists from all over the world, especially from the neighbouring countries of Belgium, Luxembourg, and The Netherlands visit the area in search of mountains and wine. However, the lack of new generations and the increase in temperatures and short heavy summer rainfall events caused by climate change endanger the production of wine.
The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications. Under the leadership of computer scientist Prof.
To effectively perform any daily task, the human brain needs to process information from the outside world using various cognitive functions. This cognitive processing passes through a dense interconnected network of cells whose physiology is specialized. The interconnected cell network needs to perform this processing of information efficiently and interact cooperatively to provide us, in real time, with useful instructions for living.
New research has for the first time compared images of the protein spikes that develop on the surface of cells exposed to the Oxford-AstraZeneca vaccine to the protein spike of the SARS-CoV-19 coronavirus. The images show that the spikes are highly similar to those of the virus and support the modified adenovirus used in the vaccine as a leading platform to combat COVID-19.
Researchers at the Francis Crick Institute, as part of an international collaboration of scientists through the Pan-Cancer Analysis of Whole Genomes Consortium, have analysed the whole genomes of tumour samples from over 2,600 patients with different types of cancer. They identified a high prevalence of genetic diversity within individual tumours, which they further characterised. Their findings confirm that, even at late stages of development, tumour evolution is driven by changes that benefit the cancer.
Digitalisation can support transitions towards a more sustainable society if technologies and processes are designed in line with suitable criteria. This requires a systemic focus on the risks and benefits of digital technologies across the three dimensions of sustainable development: the environment, society, and the economy. This is the conclusion of a study prepared by a team of researchers at the Institute for Advanced Sustainability Studies (IASS) in Potsdam. Applying this precautionary approach to digitalisation requires the active involvement of developers, users, and regulators.
ALS is a progressive neurological disease that attacks the nerves that interact with the body's muscles. The disease typically leads to complete paralysis of the body, robbing patients of their ability to walk, speak, eat and breathe.
Bishop Peder Winstrup died in 1679, and is one of the most well-preserved human bodies from the 1600s. Researchers at Lund University in Sweden may now have solved the mystery of why a foetus was hidden in his coffin in Lund Cathedral. DNA from the bishop and the foetus, along with kinship analyses, has shown that the child was probably the bishop's own grandson.
Single-cell transcriptomic methods allow scientists to study thousands of individual cells from living organisms, one-by-one, and sequence each cell's genetic material. Genes are activated differently in each cell type, giving rise to cell types such as neurons, skin cells and muscle cells.
Women are significantly underrepresented in the editorial boards of marketing academic journals, and awards and recognition favour men, new research from the University of Bath School of Management has found.
An international research team has sequenced the genomes of the oldest securely dated modern humans in Europe who lived around 45,000 years ago in Bacho Kiro Cave, Bulgaria. By comparing their genomes to the genomes of people who lived later in Europe and in Asia the researchers from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, show that this early human group in Europe contributed genes to later people, particularly present-day East Asians.
3D-mammography reduces the number of breast cancer cases diagnosed in the period between routine screenings, when compared with traditional mammography, according to a large study from Lund University in Sweden. The results are published in the journal Radiology.
"Our results indicate that 3D-mammography, or digital breast tomosynthesis, possibly detects cancers that would otherwise have been diagnosed later at a more advanced stage", says Kristin Johnson, doctoral student at Lund University and radiology resident at Skåne University Hospital.
WESTMINSTER, Colorado - April 07, 2021 - As the number of weed populations resistant to multiple herbicides continues to soar, it is clear that better tools are needed to help growers rapidly diagnose resistance issues. With more timely access to information, they can take earlier, proactive steps to keep resistant weeds from spreading.
An international team of researchers has studied individual differences in the behaviour of red deer. They found that several observed behaviours form a personality component, which they labelled "Confidence/Aggressiveness".
As is commonly known, individual people behave consistently different from each other and these kinds of consistent differences in behaviour are called personality. Studies on species other than humans, from insects to elephants, have found that personalities are widespread in nature.
