Novel broad-spectrum antiviral compounds effective against Zika and SARS-CoV-2

A research team at the University of Alberta, Canada, led by Dr. Daniel Limonta, has described two novel molecules with broad antiviral properties that are effective against a range of virus types, including SARS-CoV-2.

How do common mutations in SARS-CoV-2’s spike affect its binding affinity with host cell receptors?

Antibodies produced during a previous case of COVID-19 or vaccine-induced immunity are targeted towards S protein, where the neutralizing antibodies attach to the Spike RBD domain. Some of the variants have mutations in their RBD domain, causing resistance to the neutralizing antibodies. However, the effect of these mutations on the affinity and kinetics of the binding of Spike RBD to ACE2 is not clear. A new study has been published on the bioRxiv* preprint server, which deals with the study of affinity and kinetic analysis of the interface between Spike RBD and ACE2 at physiological temperatures.

Pfizer-BioNTech vaccination not associated with platelet activation in new study

Among the devastating complications of severe or critical coronavirus disease 2019 (COVID-19), clot formation ranks high in the adverse impact it creates. An important question is whether SARS-CoV-2-spike-based vaccines also cause such coagulopathies. A new study, released as a preprint on the medRxiv* server, examines this risk for the first time.

Risk factors for rare COVID-19 complications in children (MIS-C)

While the earlier waves of COVID-19 relatively spared children, some of the affected children have developed a systemic inflammatory condition, with occasionally fatal outcomes. Called multisystem inflammatory syndrome in children (MIS-C), its pathogenesis and risk factors are the subject of a new study on the medRxiv* preprint server.

Can SARS-CoV-2 trigger amyloidosis?

A new study, released as a preprint on the bioRxiv* server, describes the results of an analysis of the role played by the virus in amyloid formation, with its subsequent effects on the health of various organs and of the whole organism.

Scientists discover novel defensive response to SARS-CoV-2

Scientists from Hokkaido University have discovered a novel defensive response to SARS-CoV-2 that involves the viral pattern recognition receptor RIG-I. Upregulating expression of this protein could strengthen the immune response in COPD patients.

Electrospun nanofibrous filters capture 99.9 percent of coronavirus aerosols, study finds

Researchers at The George Washington University and the University of California in the U.S. compared the efficacy of surgical and cotton masks, a neck gaiter, and electrospun nanofiber membranes to capture coronavirus aerosols and prevent airborne transmission.

As pandemic eases, many seniors have lost strength, may need rehabilitative services

Ronald Lindquist, 87, has been active all his life. So, he wasn't prepared for what happened when he stopped going out during the coronavirus pandemic and spent most of his time, inactive, at home.

Masks and physical distancing could reduce SARS-CoV-2 spread to 1% among essential food plant workers, says study

The food supply is an essential service. Yet, workers in this industry are at high risk of acquiring infection with the novel coronavirus in their workplace unless proper mitigation measures are put in place. A new study, released as a preprint on the medRxiv* server, shows that the risk of infection may be reduced to less than 1% with proper precautions.

Facets of SARS-CoV-2 infection and animal models

A new study in the journal Frontiers in Cell and Developmental Biology discusses the ribonucleic acid (RNA) genome of the virus, and the mechanisms by which it establishes infection within the host cell. The researchers also summarize the development of animal models of COVID-19, which will both help understand the clinical features of the illness, and indicate new approaches for the treatment of the infection.

Researchers evaluate risk of developing new clinical conditions after acute phase of COVID-19 infection

One in 7 (14%) adults with coronavirus infection developed at least one new condition that required medical care during the post-acute phase of illness, which is 5% higher than adults with no coronavirus infection in 2020, finds a US study published by The BMJ today.

Despite frequent vaccinations, COVID-19 could continue to cause recurrent waves and deaths

Covid-19 could continue to cause recurrent waves and deaths despite frequent vaccinations according to a new study from the University of East Anglia.

Study analyzes the risk of other medical conditions after recovery from COVID-19

Researchers analyzed data from a large insurance company in the United States. They found an increased risk of other medical conditions after recovering from COVID-19 irrespective of pre-existing conditions or age.

Metal complexes against coronavirus

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused more than 3.42 million deaths worldwide. Despite the fact that there are vaccines for SARS-CoV-2, the emergence of new variants and the lack of adequate treatments have encouraged the search for new ways to combat this disease more effectively.

21 May 2021

Study shows distinctive mutation in rapidly emerging SARS-CoV-2 B.1.1.7 sublineage

In a new study currently available on the medRxiv* preprint server, US researchers report the detection of a specific sub-lineage of B.1.1.7 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant harboring a novel S:D178H mutation and elucidate its transmission and evolutionary patterns.

Total COVID-19 deaths in US counties have been underestimated by 20%, indicates study

Deaths caused by indirect effects of the pandemic emphasize the need for policy changes that address widening health and racial inequities.

SARS-CoV-2 spike mutation can independently predict viral evolution

A team of scientists from Portugal has recently estimated the rate of mutation in two circulating variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using experimental evolution methods. Their findings reveal that in a condition with no immune surveillance, SARS-CoV-2 can potentially undergo evolution during the first stages of infection. The study is currently available on the bioRxiv* preprint server.

Researchers discover new coronavirus in East Malaysia

Researchers have discovered a new coronavirus, found in a child with pneumonia in Malaysia in 2018, that appears to have jumped from dog to human.

Researchers define immune determinants of protection against SARS-CoV-2 in mice

Researchers in the United States have conducted a preclinical study defining the roles that different arms of the immune system play in fighting primary infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as reinfection and infection following SARS-CoV-2 vaccination.

21 May 2021

Pfizer-BioNTech and Sinovac vaccines boost SARS-CoV-2 neutralizing responses

Researchers in the United States and Chile have provided preliminary evidence that individuals infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – mount a robust neutralizing antibody response against the virus that can be significantly boosted by two doses of Sinovac Biotech’s CoronaVac vaccine or one dose of Pfizer-BioNTech’s BNT162b2 vaccine.
