Study reports structure of enzyme activator for high pathogenic avian influenza

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing the current pandemic of COVID-19, is the focus of many investigators seeking to find an effective vaccine or therapeutic. Among the potential targets are various protease enzymes suspected of allowing the virus to gain entry to host cells and establish a successful infection.

SARS-CoV-2 mutation reduces S1 shedding, increases infective potential

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the seventh coronavirus known to infect humans. SARS-CoV-2 emerged in the last month of 2019 in Wuhan, China, sparking off the ongoing COVID-19 pandemic. This virus enters the host cells through receptor binding and membrane fusion between the viral and host cell membrane.

Antibody cocktail is being tested in human COVID-19 trials

Following two studies that screened thousands of human antibodies to SARS-CoV-2 to identify highly potent pairs, in which both antibodies bind the viral target simultaneously, a resultant antibody cocktail is being tested in human trials.

Testing reveals 11 percent of people in Geneva infected with SARS-CoV-2

Now, a team of researchers at Geneva University Hospitals has found that less than 11 percent of the population in Geneva has contracted the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Their research is published in the journal The Lancet.

Controlling SARS-CoV-2 upon resumption of the Spanish football league

The coronavirus disease (COVID-19) pandemic first emerged in Wuhan City, China, in December 2019. Since then, it has spread throughout the world, infecting more than 8 million people. Social distancing measures were imposed in most countries, isolating people in their homes, banning congregations, including schools, parties, and even sports events.

Multilevel interventions improve overall rate of HPV vaccinations

New research from Boston Medical Center shows that providing education and training to pediatric and family medicine providers about the importance of human papillomavirus vaccines, in tandem with healthcare systems changes including starting an HPV vaccination series before the age of 11, improves the overall rate of HPV vaccinations among adolescent patients.

Human antibodies provide powerful protection against SARS-CoV-2 in animal tests

A team led by Scripps Research has discovered antibodies in the blood of recovered COVID-19 patients that provide powerful protection against SARS-CoV-2, the coronavirus that causes the disease, when tested in animals and human cell cultures.

Tracing coronavirus habitats with genomics

Now, a new study by researchers at the University of Ottawa and published on the preprint server bioRxiv in June 2020 reports the differences in genomes of viruses that are exposed to antiviral proteins vs. those that are not. This host-derived pressure on the virus to adapt may help devise newer ways to build an effective vaccine.

Inhaled steroids reduce ACE2 expression in COPD lungs

A new study by scientists at Imperial College London, University of Newcastle and Prokarium, and published on the preprint server bioRxiv* in June 2020 examines the role played by inhaled corticosteroids (ICS) in the risk of acquisition of COVID-19 infection by COPD patients.

U.S. and European SARS CoV-2 mutation enhances transmission, increases infectivity

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is causing the COVID-19 pandemic across the world has undergone a genetic mutation in the density of functional spikes on the virus, says a new study. This has led the virus to become highly infectious and easily transmissible between humans.

Experimental drug to prevent deadly blood coagulation in patients with COVID-19

The British Heart Foundation is funding a trial for an experimental drug that could prevent the life-threatening blood clots that are seen in the lungs of the patients with COVID-19 or those infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The drug named TRV027 is said to normalize the hormonal imbalance that can be seen in patients developing COVID-19, experts said.

Deep vein thrombosis common in patients with moderate to severe COVID-19

In their paper available on the medRxiv preprint server, researchers from Russia showed that patients with moderate and severe coronavirus disease (COVID-19) have a high incidence of deep vein thrombosis – indicating that they may necessitate an early administration of anticoagulation therapy as a part of their treatment regimen.

Nasal swab tests miss low viral SARS-CoV-2

A recent study by researchers from Beth Israel Deaconess Medical Center and Harvard Medical School, currently available on the preprint server medRxiv, demonstrates how nasal swab samples reliably detect patients infected with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that present with high viral loads, but may miss many patients with lower viral loads – questioning their role as a sole specimen for diagnostic purposes.
