Researchers have identified a new druggable target for heart failure in neonates and infants, a condition for which there has been no specific treatment. Approximately 60 percent of children born with congenital heart abnormalities will develop overt heart failure within the first year of life. The progression of heart failure in these infants is often rapid, with a high frequency of fatalities.
A UC Davis Health pediatric team presented a powerful case series of three teenagers who had unexplained breathing problems during the COVID-19 pandemic. The series highlighted the similarities between e-cigarette, or vaping, product use-associated lung injury (EVALI) and COVID-19 symptoms and manifestations.
The antiviral drug remdesivir is not suggested for patients admitted to hospital with covid-19, regardless of how severely ill they are, because there is currently no evidence that it improves survival or the need for ventilation, say a WHO Guideline Development Group (GDG) panel of international experts in The BMJ today.
DALLAS - Nov. 19, 2020 - Pregnant women who test positive for COVID-19 and their newborn babies have a low risk of developing severe symptoms, according to a new study from UT Southwestern.
Dr Zi Yang MENG from Division of Physics and Astronomy, Faculty of Science, the University of Hong Kong (HKU), is pursuing a new paradigm of quantum material research that combines theory, computation and experiment in a coherent manner. Recently, he teamed up with Dr Wei LI from Beihang University, Professor Yang QI from Fudan University, Professor Weiqiang YU from Renmin University and Professor Jinsheng WEN from Nanjing University to untangle the puzzle of Nobel Prize-winning theory Kosterlitz-Thouless (KT) phase.
How do people experience time alone and time with others? Findings from a new Bar-Ilan University study reveal the intricacies of people's experiences in these basic social conditions.
The study used a unique approach of analyzing self-generated text from more than 1,700 participants who performed a sentence-completion task regarding their experience alone and their social experience when in the company of others. This approach shed light on people's perceptions when free to express themselves without being bound to specific questions.
It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called "photoelectrons". In materials research, so-called "Auger electrons" also play an important role - they can be emitted by atoms if an electron is first removed from one of the inner electron shells. But now scientists at TU Wien (Vienna) have succeeded in explaining a completely different type of electron emission, which can occur in carbon materials such as graphite.
The largest freshwater bacterium, Achromatium oxaliferum, is highly flexible in its requirements, as researchers led by the IGB have now discovered: It lives in places that differ extremely in environmental conditions such as hot springs and ice water. The bacterial strains from the different ecosystems do not differ in their gene content, but rather chose what to express. The adaptation is probably achieved by a process which is unique to these bacteria: only relevant genes are enriched in the genomes and transcribed, while others are archived in cell compartments.
In normal circumstances, particles will follow well-established random motions as they diffuse through liquids and gases. Yet in some types of system, this behaviour can be disrupted - meaning the diffusion motions of particles are no longer influenced by the outcomes of chains of previous events. Through research published in EPJ E, Bernhard Mitterwallner, a Ph.D. student in the team of Roland Netz at the Free University of Berlin, Germany, has developed new theories detailing how these unusual dynamics can be reproduced in generalised mathematical models.
Pairs of antibodies may be more effective than single antibodies at preventing and treating COVID-19, according to a new study by researchers at the University of North Carolina at Chapel Hill and The Rockefeller University in New York.
A study published today in JAMA Network Open/Emergency Medicine supports evidence that older persons admitted to emergency departments (ED), and subsequently diagnosed positive for COVID-19, often present with delirium when they show no other typical COVID-19 symptoms, such as fever and cough.

A collaborative research team from the University of Oklahoma, the Memorial Sloan Kettering Cancer Center
and Merck & Co. published an opinion article in the journal, Nature Chemical Biology, that addresses the gap in the discovery of new antibiotics.

Systematic review and meta-analysis of three human coronaviruses suggests that people infected with SARS-CoV-2 are most likely to be highly infectious in the first week after symptom onset, highlighting the need to identify and isolate cases early.
Announcing a new article publication for BIO Integration journal. In this article the authors Zhong, Cuiyu; Zhang, Lei; Huang, Jiandong; Huang, Songyin; Yao, Yandan from Sun Yat-sen University, Guangzhou, China; Guangzhou Regenerative Medicine and Health Guangdong Laboratory, Guangzhou, China and Shenzhen Institutes of Advanced Technology, Guangdong, China review antimicrobial peptides with anticancer properties.
The African crested rat (Lophiomys imhausi) is hardly the continent's most fearsome-looking creature--the rabbit-sized rodent resembles a gray puffball crossed with a skunk--yet its fur is packed with a poison so lethal it can fell an elephant and just a few milligrams can kill a human.
