Could rapid result low sensitivity SARS-CoV-2 tests improve pandemic quarantine strategies?

Researchers in the USA have re-examined current testing and quarantining regimens for SARS-CoV-2. They suggest that the RT-PCR method and 14-day isolation rule may not be the most effective approach in managing viral transmission.

Researchers engineer "Nanotraps" that block SARS-CoV-2 infection

Researchers at Chicago University have developed an innovative new anti-SARS-CoV-2 therapy called “Nanotraps” – a family of nano-enabled virus-trapping particles – which have shown positive results in vitro, in vivo, and in human ex vivo trials.

100 million covid shots in 100 days doesn’t get us back to normal

April 30 will mark the end of the first 100 days of President Joe Biden's tenure. That's a benchmark presidents often set for making good on high-priority campaign promises.

Researchers survey repurposed drugs that inhibit SARS-CoV-2 replication in vitro

A new study by researchers at the University of Manchester, UK, reports on the compounds of interest that were identified as having potential for the treatment of COVID-19, from a library of almost 2,000 compounds from the APExBIO DiscoveryProbe library.

Genomic study suggests SARS-CoV-2 clade 20C was imported into Japan from the US

A new study describes the outcome of such sequencing efforts in Japan as an important tool towards containing the spread of the infection.

Long COVID-19 symptoms not associated with reduced cell-mediated immunity, finds study

A new preprint examines Long COVID-19, aiming to identify the underlying immunologic status in such patients.

3 Feb 2021

Oxysterol derivatives show powerful antiviral activity against SARS-CoV-2 in vitro

A new study describes the antiviral activity of oxysterols, or oxidized cholesterol derivatives, against SARS-CoV-2. These occur in nature, and are not only involved in lipid signaling pathways that modulate a host of processes within the body, including the immune response and lipid homeostasis.

Study finds higher pediatric SARS-CoV-2 burden than previously reported in the U.S.

In a new study, published on the pre-print server medRxiv*, researchers at Inova Children's Hospital and the George Mason University revealed that a much higher burden of SARS-CoV-2 infection was found in children than previously reported. This comes after the researchers assessed seropositivity among 1,038 children and adolescents.

Researchers report trial results of rectal microbicides at HIV R4P Virtual Conference

Researchers seeking to develop on-demand and behaviorally congruent HIV prevention options for people who practice anal sex are reporting the results of three early phase clinical trials of rectal microbicides at this week's HIV Research for Prevention (HIV R4P) Virtual Conference.

Study examines motivations and barriers to convalescent plasma donation in the UK

Researchers have given new insights into why people would choose to donate Covid-19 plasma after recovering from the virus, which will be used to support the recruitment of convalescent plasma donors to help treat current Covid-19 patients and support ongoing trials.

Airborne Infection Rate index predicts timing of second wave of pandemic

The "second wave" of the coronavirus pandemic has placed much blame on a lack of appropriate safety measures. However, due to the impacts of weather, research suggests two outbreaks per year during a pandemic are inevitable.

Key variants help explain the differences between viruses that cause COVID-19 and SARS

An effort led by Lin Li, Ph.D., assistant professor of physics at The University of Texas at El Paso, in collaboration with students and faculty from Howard University, has identified key variants that help explain the differences between the viruses that cause COVID-19 and Severe Acute Respiratory Syndrome (SARS).

New genome editing technology could pave way for non-viral delivery systems

Researchers from Peter the Great St.Petersburg Polytechnic University (SPbPU) in collaboration with colleagues from Belgium take a step in the development of genome editing technology.

One dose of VSV-vectored vaccine prevents SARS-CoV-2 replication in hamsters

A new preprint research paper posted to the bioRxiv server describes a viral vector vaccine candidate's efficacy to protect against SARS-CoV-2 replication in a hamster model.

3 Feb 2021

Study could help understand mechanisms of drug molecules to mitigate COVID-19 infection

As the scientific community continues researching the novel coronavirus, experts are developing new drugs and repurposing existing ones in hopes of identifying promising candidates for treating symptoms of COVID-19.

J&J SARS-CoV-2 vaccine shows immunity in non-human primates 6 months after vaccination

A new preprint research paper released on the bioRxiv server discusses the findings from a model that assesses the association between the immunogenicity and protection conferred by a set of adenovirus- (Ad26)-vectored vaccines that express stabilized SARS-CoV-2 spike protein.

Rapid SARS-CoV-2 antigen test improved with silver amplification

A new preprint posted to the medRxiv server describes the use of silver amplification technology to develop a sensitive, rapid antigen test for COVID-19.

2 Feb 2021

Prone positioning associated with lower mortality and intubation in COVID-19 patients

In the absence of specific antivirals to combat the pandemic, supportive care is paramount. In this context, a new preprint posted to the medRxiv server describes the observed efficacy of prone positioning to reduce mortality and the risk of intubation in COVID-19 patients with respiratory insufficiency.

Single-dose vaccination effective for healthcare workers with prior SARS-CoV-2 infection

The findings reveal that healthcare workers previously infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) develop significantly higher antibody titers in response to a single dose of COVID-19 vaccine, as compared to healthcare workers without prior SARS-CoV-s infection. The study is currently available on the medRxiv* preprint server.

2 Feb 2021

Highly conserved neutralizing epitope identified on SARS-CoV-2 spike protein

A recent study conducted at the University of Texas at Austin, USA, has identified a highly conserved neutralizing antibody binding site on the spike S2 domain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The study findings might help develop novel spike-targeting antibodies for widespread protection. The study is currently available on the bioRxiv preprint server.
