Feasibility of using dry reagents LAMP assay for SARS-CoV-2 detection

In a new study published on the preprint server medRxiv, researchers evaluated the suitability of the Loopamp SARS-CoV-2 Detection kit from Eiken Chemica, Japan, for detecting SARS-CoV-2. This is a LAMP method that uses dry reagents for RNA amplification.

Researchers determine the predictability of Ebola's trajectory in China and throughout Southeast Asia

What exactly happened in Asia that caused SARS-CoV-2 to rapidly spread across the region and then essentially came to a halt there? That's what researchers from the University of South Florida are trying to determine in a new study funded by an NSF Rapid Response grant.

Another study finds cross-reactivity T cell responses against SARS-CoV-2

Using ELISpot and proliferation assays, researchers show strong responses in SARS-CoV-2 infected patients, but not so much in negative samples. However, there may be cross-reactive T cell responses from other human coronaviruses.

AbC-19 blood test detects COVID-19 antibodies 20 weeks after first symptoms/PCR positive result

Serological antibody immunoassays are one of the essential tools to combat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. In a new study, Immunoglobulin G (IgG) antibodies are detected in a large cohort, lasting up to 140 days. The researchers propose an alternative to reverse transcription-polymerase chain reaction (RT-PCR) positive status as a standard for assessing SARS-CoV-2 antibody assays and show robust performance metrics for the AbC-19 rapid test.

Investigation of SARS-CoV-2 antibody responses in patients with aggressive hematological malignancies

Patients with hematological malignancy (PHM), also infected with COVID-19, were investigated for SARS-CoV-2 antibody responses while undergoing systemic anti-cancer therapy. While no obvious correlation is found between the serological results and the hematological diagnosis and the treatment, the immune response is similar to the severity of COVID-19 infection observed in the general population.

The implications of COVID-related sexual distancing and clinical service interruption

A recent study conducted in the Atlanta area reveals that coronavirus disease 2019 (COVID-19) related sexual distancing together with clinical service interruption for sexually transmitted diseases can potentially impact the future incidence of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs). The study is currently available on the medRxiv* preprint server.

More evidence Pangolin not intermediary in transmission of SARS-CoV-2 to humans

The team proposed a different model named the ‘circulation model’ to illustrate how SARS-CoV-2-related coronaviruses could have circulated in different species, including humans, before COVID-19 emerged.

NPIs reduced SARS-CoV-2 transmission in South Korea

Although some studies examined how public health interventions can help contain COVID-19 outbreaks, not much information was available on public health measures against SARS-CoV-2 transmission, specifically in South Korea.

Rapid detection of SARS-CoV-2 with portable CRISPR-based mobile phone diagnostic test

A large group of researchers from the United States reported developing an amplification-free CRISPR-based mobile phone assay for direct detection of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from nasal swabs. Their state-of-the-art paper is currently available on the medRxiv* preprint server.

Furin cleavage site of SARS-CoV-2 spike glycoprotein enhances viral replication in the lungs

In a new bioRxiv* preprint paper, researchers from the Imperial College London, King's College London, and the University of Bristol in the United Kingdom show that the furin cleavage site of SARS-CoV-2 spike glycoprotein represents a key determinant for transmission among humans, as it substantially facilitates replication in airway cells - opening the door for the development of novel therapeutics.

Modeling viral clades improves prediction of COVID-19 growth rates

A new study conducted by researchers at the University of Connecticut has revealed a correlation between the prevalence of particular clades of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the growth rate of the associated illness coronavirus disease 2019 (COVID-19).

Shedding light on origin, transmission, spread of COVID-19 in Norfolk

Researchers in the UK have conducted a large-scale whole-genome sequencing study of clinical samples positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the Norfolk area to shed light on the origins, genetic variation, transmission, and spread of the virus in the region.

Anti-sense agents suppress SARS-CoV-2 virus

Researchers in the United States have conducted a study showing that anti-sense agents called peptide-conjugated morpholino oligomers (PPMOs) have the ability to specifically and potently suppress the growth of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Study reveals how immune cells sacrifice themselves to help fight off infections

Whether flu or coronavirus, it can take several days for the body to ramp up an effective response to a viral infection.

New multiplexed test with a low-cost sensor may enable at-home COVID diagnosis

One feature of the COVID-19 virus that makes it so difficult to contain is that it can be easily spread to others by a person who has yet to show any signs of infection.

$9.1 million NCI grant renewal will support researchers studying retrovirus cancer models

The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute and The Ohio State University College of Veterinary Medicine have been awarded a five-year, $9.1 million grant Program Project Grant renewal from the National Cancer Institute.

Researchers develop AI algorithm to evaluate chest X-rays for COVID-19 diagnosis

A team of researchers at the University of Minnesota recently developed and validated an artificial intelligence algorithm that can evaluate chest X-rays to diagnose possible cases of COVID-19.

In-depth analysis of coronavirus genome sequence in Norfolk identifies hidden outbreaks

An in-depth analysis of the genome sequence of coronavirus circulating in Norfolk, UK by researchers at the Quadram Institute and University of East Anglia has mapped the spread of the virus, identified hidden outbreaks and provided insights into the effectiveness of interventions to stop its spread.

Researchers identify 'social cells' in the brain linked to social behavior

A research team led by Professor TAKUMI Toru of Kobe University's Graduate School of Medicine (also a Senior Visiting Scientist at RIKEN Center for Biosystems Dynamics Research) have identified 'social cells' in the brain that are related to social behavior. The cells were identified via Ca imaging conducted using a microendoscope .

Work bubbles can help reduce risk of company-wide COVID-19 outbreaks

Creating "work bubbles" during the COVID-19 pandemic can help reduce the risk of company-wide outbreaks while helping essential businesses continue to function, as the example of Bombardier Aviation demonstrates in an analysis published in CMAJ (Canadian Medical Association Journal).
