Looking beyond the numbers to see pandemic's effect on nursing home residents
INDIANAPOLIS -- Nursing homes throughout the United States have been devastated by the COVID-19 pandemic with many perceptions and misperceptions but little documentation about what has happened on a day-by -day basis to residents in these facilities. A study from Regenstrief Institute and Indiana University School of Medicine research scientists is one of the first to describe and identify patterns in the course of COVID-19 in the typically frail individuals who reside in nursing homes. Much has been written about number of deaths, vaccine uptake and ...
Silicon in drinking water caused irreversible lung pathologies in rodents
Bone density, skin and hair health, and the mobility of joints depend to a great extent on the microelement of silicon. We mostly get it with food, but silicon is also consumed with some biologically active additives that promise beauty, longevity, and youth. The element can also be found in drinking water of a natural origin: usually, it is included in the compound of sodium salt and metasiliconic acid. However, in the case of microelements, one should be extremely careful: a deficiency could lead to diseases, but an overdose could bring negative effects too. Together with colleagues from the Chuvash State University and the Hamburg Medical University, scientists of Immanuel Kant Baltic Federal University studied the effect of prolonged silicon consumption in relatively ...
The virus trap
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses. There are antibiotics against dangerous bacteria, but few antidotes to treat acute viral infections. Some infections can be prevented by vaccination but developing new vaccines is a long and laborious process. Now an interdisciplinary research team from the Technical University of Munich, the Helmholtz Zentrum München and ...
Study highlights how resilience is dynamic, not a static character trait
A new study finds that resilience is a dynamic process, rather than a fixed trait - and suggests this may have significant ramifications for the business world. "Organizations are interested in cultivating a resilient workforce, because they want people who are able to remain committed to an organization and its goals over time," says Patrick Flynn, corresponding author of the study and an assistant professor of human resources management at North Carolina State University's Poole College of Management. "Our work here does a couple things," Flynn says. "First it finds that resilience is more of a process than a characteristic. Second, it identifies some of the ...
RUDN University chemists obtained an unusual planar nickel complex exhibiting magnetic properties
RUDN University chemists obtained a metal-containing complex with an unusual planar architecture. The unexpected structure was formed due to the spontaneous fixation of carbon dioxide from the air during the reaction. This compound exhibits unusual magnetic properties (spin glass behaviour). This can be useful for creating memory storage devices. The results are published in the Journal of Organometallic Chemistry Coordination polymers are hybrid crystalline coordination compounds contained of infinitely repeating fragments (structural elements). These structural ...
Researcher creates cell lines to help treat mitochondrial diseases in children
The mitochondrion has garnered quite the reputation for its role as the "powerhouse of the cell." These tiny, but mighty organelles play various life-sustaining roles, from powering our own cells and organs to fueling chemical and biological processes. But when they aren't working properly, a number of rare diseases can occur. Mitochondrial diseases are a group of debilitating genetic disorders that affect one in 5,000 people throughout the world, most of them being children. Along with these diseases come a variety of health concerns including, but not limited to, heart ...
Digital assistants created for e-commerce which adapt themselves to each shop's needs
The pandemic has taught us that almost all companies have to sell on the internet. Bots are a technology that facilitates e-commerce. They are digital assistants that can answer customer queries about products that are sold or help to locate them, as well as supporting customers in the purchasing process. "In whatever language; and moreover, chatbots never get tired: They're available 24 hours a day, 365 days a year", said Jordi Cabot, the Universitat Oberta de Catalunya (UOC) researcher who created Xatkit, a company specialized in their development. This technology has existed for some time in big companies and is now also helping improve the digital competitiveness ...
RUDN University chemists propose a one-step synthesis of substances for medicine
The RUDN University chemists have discovered a reaction for the synthesis of acetimidamides, heterocyclic compounds with biological activity that can be used for the synthesis of hormones, anti-inflammatory and other medical drugs. The reaction goes in one step with an efficiency of up to 96%. The results are published in the journal Molecules. Traditional chemical synthesis goes in several stages and requires the isolation and purification of intermediates at each stage. It is not efficient and not environmentally friendly as it increases the loss of substances and the consumption of solvents, and there is a problem of waste disposal. ...
Bioengineering discovery paves way for improved production of bio-based goods
Scientists have uncovered a way to control many genes in engineered yeast cells, opening the door to more efficient and sustainable production of bio-based products. The study, published in Nucleic Acids Research by researchers from DSM's Rosalind Franklin Biotechnology Center in Delft, the Netherlands, and the University of Bristol, has shown how to unlock CRISPR's potential for regulating many genes simultaneously. Baker's yeast, or Saccharomyces cerevisiae to give it it's full name, is considered as a workhorse for biotechnology. Not only has it been used for producing bread and beer for thousands of years, but today it can also be engineered to produce an array of other useful compounds that form the basis of pharmaceuticals, fuels, and food additives. However, achieving ...
Tracking COVID-19 across Europe
According to the World Health Organization, a third wave of COVID infections is now all but inevitable in Europe. A COVID tracker developed by IIASA researcher Asjad Naqvi, aims to identify, collect, and collate various official regional datasets for European countries, while also combining and homogenizing the data to help researchers and policymakers explore how the virus spreads. While many comparisons have been made between the COVID-19 pandemic and similar events in history, one thing sets this pandemic apart from others: the unprecedented amount of knowledge and data that is constantly being generated to understand how the pandemic is unfolding. For a high-income region like Europe, the quality of information made available on a daily basis is exceptionally ...
