SARS-CoV-2 Neucleocapside (N) protein is heavily glycosylated

However, the nucleocapsid (N) protein is also extremely abundant and, therefore, a useful target for both vaccine and diagnostic test development. A new study published on the preprint server bioRxiv in August 2020 reveals the structure of this protein, a valuable step in using it for these purposes.

Severe and fatal COVID-19 is rare in children

Now, a new study by researchers at the Universities of Edinburgh and Liverpool, Imperial College London, and the Royal Hospital for Children, Glasgow in the United Kingdom has shown that children and teenagers are less likely than adults to develop severe COVID-19 or die from the disease.

Evidence of SARS-CoV-2 spreading in an airplane toilet

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease (COVID-19), is still actively spreading like wildfire, with nearly 300,000 new infections reported daily across the globe. Early on in the outbreak in China, scientists said that the virus could spread through respiratory droplets, when a person coughs, sneezes, or speaks.

Study may help explain the symptoms and organs involved with SARS-CoV-2 infection

A study of a gateway receptor for SARS-CoV-2 led by Walter Lukiw, PhD, Professor of Neuroscience, Neurology and Ophthalmology at LSU Health New Orleans' Neuroscience Center of Excellence and School of Medicine, may help explain the wide variety of symptoms and organs involved with SARS-CoV-2 infection and COVID-19.

Serious heart complications are common in adults hospitalized with flu

The link between influenza and serious heart conditions just grew stronger. A CDC study looking at more than 80,000 adult patients hospitalized with flu over eight seasons found that sudden, serious heart complications were common, occurring in 12% of patients, or 1 in 8.

Influenza, pneumonia vaccinations associated with fewer deaths in heart failure patients

Influenza and pneumonia vaccinations are associated with fewer hospital deaths in patients with heart failure. That's the result of a study in nearly 3 million Americans released today at ESC Congress 2020.

FDA grants Abbott's COVID-19 rapid antigen test emergency-use authorization

Now, the U.S. Food and Drug Administration has granted emergency-use authorization to Abbott Laboratories for a $5 rapid-response COVID-19 antigen test, called BinaxNOW COVID-19 Ag Card, which is roughly the size of a credit card.

Blood thinners help reduce the risk of COVID-19 deaths, study finds

Now, a new study by a team of researchers at the Mount Sinai Health System in New York has shown that blood thinners may reduce the risk of death by up to 50 percent among severely ill hospitalized COVID-19 patients.

New low-cost COVID-19 test quickly delivers accurate results

A new low-cost diagnostic test for coronavirus disease 2019 (COVID-19) quickly delivers accurate results without the need for sophisticated equipment, according to a study published August 27 2020 in the open-access journal PLOS Pathogens by Teng Xu of the Vision Medicals Center for Infectious Diseases, Tieying Hou of the Guangdong Academy of Medical Sciences, Bing Gu of the Affiliated Hospital of Xuzhou Medical University, Jianwei Wang of the Chinese Academy of Medical Sciences and Peking Union Medical College, and colleagues.

Study shows furin cleavage site is crucial for SARS-CoV-2 replication

In a recent bioRxiv* preprint paper, researchers from the United States demonstrate the pivotal role the furin cleavage site insertion in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein plays in viral replication and pathogenesis – highlighting, in turn, the need for mutation monitoring when developing therapeutics and vaccines.

Evidence of SARS-CoV-2 coronavirus particles in heart tissue

Researchers in Milan, Italy, have identified the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the heart tissue of deceased coronavirus disease 2019 (COVID-19) patients who had died from respiratory failure, without showing any signs of cardiac involvement.

Two viral gene targets needed in SARS-CoV-2 detection by PCR, say researchers

Researchers at the Chan Zuckerberg Biohub, San Francisco, and collaborators have warned against only targeting one viral gene when carrying out reverse transcriptase-polymerase chain reaction (RT-PCR) testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

First lethal mouse model of SARS-CoV-2 developed

Army scientists have developed the first lethal mouse model of SARS-CoV-2, the virus that causes COVID-19, using mice that were genetically engineered to express the human ACE2 gene--a key mechanism by which the virus enters human cells.

NIAID awards $17 million to establish the Centers for Research in Emerging Infectious Diseases

The National Institute of Allergy and Infectious Diseases, one of the National Institutes of Health, today announced that it has awarded 11 grants with a total first-year value of approximately $17 million to establish the Centers for Research in Emerging Infectious Diseases.

BMI in first years of life can affect lung function in later childhood

Body mass index (BMI) trajectories in the first years of life may be associated with lung function in later childhood. For example, children with accelerated BMI gain before age four years have higher lung function at age seven years, although they also exhibit airflow limitation.

Scientists say insect repellent kills the SARS-CoV-2 coronavirus on surfaces

Now, a team of scientists at Britain's Defence Science and Technology Laboratory (DSTL) has shared preliminary findings of their research, showing that a product in insect repellent can kill the SARS-CoV-2 virus.

Interventions can successfully reduce the rate of inappropriate antibiotic prescriptions

Two different interventions both worked to significantly reduce the rate of inappropriate antibiotic prescriptions made by physicians in a telemedicine practice, a new study led by Children's National Hospital researchers shows.

Coronavirus can spread through drain pipes in bathrooms, study suggests

Now, a new study reveals that the virus may spread via aerosols through drain pipes in bathrooms, after scientists examined an abandoned apartment in Guangzhou, China. The findings add to the body of evidence suggesting the virus is transmissible via aerosols.

Obesity ups COVID-19 death risk by 48 percent

Now, a new study by researchers from the University of North Carolina (UNC), the World Bank, and Saudi Health Council, shows that obesity increases the risk of dying from COVID-19 by as much as 48 percent, hinting that a vaccine against the virus could be less effective in obese people.
