Study IDs risk factors for irregular heartbeats in hypertrophic cardiomyopathy patients
2021-07-15
New research will help doctors identify, treat and prevent potentially dangerous irregular heartbeats in patients with hypertrophic cardiomyopathy (HCM), a common heart condition in which the heart thickens and strains to pump blood.
These chaotic heart rhythms are known as atrial fibrillation. Atrial fibrillation can be asymptomatic, but it can lead to blood clots, stroke or even heart failure. The new research, from an international team of doctors and scientists, identifies risk factors for major atrial fibrillation outcomes, such as the need for procedures or hospitalization for more than 24 ...

Silicon in drinking water caused irreversible lung pathologies in rodents
2021-07-15
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
2021-07-15
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
2021-07-15
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 ...

Digital assistants created for e-commerce which adapt themselves to each shop's needs
2021-07-15
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
2021-07-15
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. ...

Caring for the physical health of those with mental illness
2021-07-15
PHILADELPHIA - People who struggle with serious mental illnesses are more likely to die early - about 10 to 30 years early - than those without mental illness from any cause. Many factors contribute to this disparity including poor access to care, undetected health conditions and difficulty managing chronic health conditions. Addressing physical illness in those with serious mental illness has been a major challenge. To address this, researchers tested a peer-led intervention called the Bridge that helps patients with mental illness prioritize their health, access health care and develop skills to self-manage their health. The approach showed a 50% reduction in emergency room use for those in ...

Thinking without a brain
2021-07-15
If you didn't have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be "yes." Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and performs computations similar to what we call "thinking" to decide in which direction to grow based on that information. Unlike previous studies with Physarum, these results were obtained without giving ...

Removing the lead hazard from perovskite solar cells
2021-07-15
"The solar energy-to-electricity conversion of perovskite solar cells is unbelievably high, around 25%, which is now approaching the performance of the best silicon solar cells," says Professor László Forró at EPFL's School of Basic Sciences. "But their central element is lead, which is a poison; if the solar panel fails, it can wash out into the soil, get into the food chain, and cause serious diseases."
The problem is that in most of the halide perovskites lead can dissolve in water. This water solubility and solubility in other solvents is actually a great advantage, as it makes building perovskite solar panels simpler and inexpensive - another perk along with their ...

Teens with secure family relationships "pay it forward" with empathy for friends
2021-07-15
Teens' ability to empathize -- to understand others' perspectives and emotions, and to care for their wellbeing -- is an important contributor to their relationships, including with friends. Prior research shows that teens who have more secure family relationships report higher levels of empathy for others. But little research examines whether teens with more secure family relationships actually show greater empathy when observed in real-life interactions with peers, or whether their empathic capacities show different patterns of growth over time.
A new study tested whether ...
