Association of age with likelihood of developing symptoms, critical disease among close contacts exposed to patients with confirmed SARS-CoV-2 infection

2021-03-10
(Press-News.org) What The Study Did: In a study of Italian close contacts of patients with confirmed SARS-CoV-2 infection, most infected contacts (1,948 of 2,824 individuals or 69%) didn't develop respiratory symptoms or fever 37.5 degrees Celsius (99.5 degrees Fahrenheit) or higher; 26.1% of infected individuals younger than 60 developed respiratory symptoms or fever 37.5 degrees Celsius (99.5 degrees Fahrenheit); and 6.6% of infected participants age 60 or older developed critical disease.

Authors: Piero Poletti, Ph.D., of Fondazione Bruno Kessler in Trento, Italy, and Marcello Tirani, M.D., Directorate General for Health, Lombardy Region, in Milan, Italy, are the corresponding authors.

Implementation of recuperation unit, hospitalization rates among people experiencing homelessness with COVID-19

2021-03-10
What The Study Did: Boston experienced a COVID-19 surge that disproportionately affected persons experiencing homelessness and a large safety-net hospital implemented a novel COVID-19 recuperation unit for these patients that provided isolation, quarantine and treatment for substance use. Researchers aimed to determine the association of the care provided by the unit with COVID-19 hospitalizations among people experiencing homelessness. Authors: Joshua A. Barocas, M.D., of Boston Medical Center, is the corresponding author. To ...

Assessment of acute kidney injury, longitudinal kidney function after hospital discharge among patients with, without COVID-19

Placenta is a dumping ground for genetic defects

2021-03-10
In the first study of the genomic architecture of the human placenta, scientists at the Wellcome Sanger Institute, the University of Cambridge and their collaborators have confirmed that the normal structure of the placenta is different to any other human organ and resembles that of a tumour, harbouring many of the same genetic mutations found in childhood cancers. The study, published today (10 March 2021) in Nature, found evidence to support the theory of the placenta as a 'dumping ground' for genetic defects, whereas the fetus corrects or avoids these errors. The findings provide a clear rationale for studying the association between genetic aberrations and birth outcomes, in order to better understand problems such as premature birth and stillbirth. In the earliest ...

The 3Rs of the genome: Reading, writing, and regulating

The 3Rs of the genome: Reading, writing, and regulating
2021-03-10
A massive effort to map the precise binding locations of over 400 different kinds of proteins on the yeast genome has produced the most thorough and high-resolution map of chromosome architecture and gene regulation to date. The study reveals two distinct gene regulatory architectures, expanding the traditional model of gene regulation. So-called constitutive genes, those that perform basic 'housekeeping' functions and are nearly always active at low levels require only a basic set of regulatory controls; whereas those that that are activated by environmental signals, known as inducible genes, have a more specialized architecture. This finding in yeast could open the ...

Fossil lamprey larvae overturn textbook assumptions on vertebrate origins

Fossil lamprey larvae overturn textbook assumptions on vertebrate origins
2021-03-10
The unprecedented discovery of an ancient lamprey growth series, published in the prestigious scientific journal, Nature, is overturning long-held ideas as to what modern lampreys may tell us about the origin of vertebrates (all animals with a backbone such as goldfish, lizards, crows and people). "Lampreys and modern hagfish are the only jawless fish alive that branched off from the family tree of vertebrates before they got jaws," says Dr Rob Gess from the Albany Museum in Makhanda, who discovered the ancient fossils. "This makes them very interesting for researchers attempting to understand the earliest stages of vertebrate history." Until now, it was commonly believed that modern lampreys were swimming ...

Reflecting on your own capabilities boosts resilience

2021-03-10
The unpredictable nature of life during the coronavirus pandemic is particularly challenging for many people. Not everyone can cope equally well with the uncertainty and loss of control. Research has shown that while a large segment of the population turns out to be resilient in times of stress and potentially traumatic events, others are less robust and develop stress-related illnesses. Events that some people experience as draining seem to be a source of motivation and creativity for others. These differing degrees of resilience demonstrate that people recover from stressful events ...

Are 'bacterial probiotics' a game-changer for the biofuels industry?

Are bacterial probiotics a game-changer for the biofuels industry?
2021-03-10
In a study recently published in Nature Communications, scientists from The Novo Nordisk Foundation Center for Biosustainability (DTU) and Yale University have investigated how bacteria that are commonly found in sugarcane ethanol fermentation affect the industrial process. By closely studying the interactions between yeast and bacteria, it is suggested that the industry could improve both its total yield and the cost of the fermentation processes by paying more attention to the diversity of the microbial communities and choosing between good and bad bacteria. The scientists dissected yeast-bacteria interactions in sugarcane ethanol fermentation by reconstituting every possible combination ...

The secret of catalysts that increase fuel cell efficiency

The secret of catalysts that increase fuel cell efficiency
2021-03-10
Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction efficiency is directly connected to the performance of the fuel cell. To this, a POSTECH-UNIST joint research team has taken a step closer to developing high-performance catalysts by uncovering the ex-solution and phase transition phenomena at the atomic level for the first time. A joint research team of Professor Jeong Woo Han and Ph.D. candidate Kyeounghak Kim of POSTECH's Department of Chemical Engineering, and Professor Guntae Kim of UNIST have uncovered the mechanism by which PBMO - a catalyst used ...
