Researchers identify a novel SARS-CoV-2 variant (A.VOI.V2) in southern Africa

Scientists recently explored the transmission dynamics of currently circulating variants of SARS-CoV-2 in a southern African country. By analyzing the genomic sequences of these variants, they have identified a novel SARS-CoV-2 variant with multiple spike mutations. They have temporarily designated the variant A.VOI.V2.

Can limiting the priming dose of a SARS-CoV-2 vaccine improve immunity?

Researchers from Northwestern University and the University of Rochester in the U.S. addressed this question in their study. The researchers also explored whether the vaccines administered across the world could confer sterilizing immunity while preventing severe disease and death.

Is non-severe SARS-CoV-2 infection characterized by early T cell proliferation?

To date, little evidence has been documented regarding the immune responses after the onset of the symptoms or virus detection. Further, no cross-sectional studies have been conducted that define the time of infection. Thereby, no report is available that explains the relationship between the earliest immune responses to COVID-19 and temporal kinetics. New research deals with this research gap using blood transcriptomics, multiparameter flow cytometry, and T cell receptor (TCR) sequencing methods.

Study suggests T-cells don't determine survival in severe COVID-19

In the study, which appeared on the pre-print server medRxiv, the team found that when the monkeys were reinfected, the T cell-depleted animals showed anamnestic immune responses, the enhanced reaction of the body's immune system to an antigen that is related to an antigen previously encountered.

Research shows efficacy of early warning signals for disease emergence amid COVID-19

The study, published on the pre-print server medRxiv, shows that early warning signals (EWS) provide expected trends, predicting future epidemics and disease emergence.

Novel hydrogel-based vaccine formulation shows high efficacy against SARS-CoV-2

A fascinating new preprint research paper posted to the bioRxiv* server discusses impressively high neutralizing responses elicited with a single dose of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine formulation, which could help turn the tide of the current pandemic if validated.

Study highlights need to optimize telehealth and in-person emergency care

Even before the pandemic made telehealth a hot topic, people with minor urgent health needs had started to turn to companies that offer on-demand video chats with physicians that they don't normally see.

Research explores sex differences in placental defenses against SARS-CoV-2 infection

A plethora of earlier studies has reported on the differences between the sexes in susceptibility to the currently circulating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as its severity. A new preprint research paper posted to the bioRxiv* server extends this to the placenta in pregnancy.

South Africa SARS-CoV-2 variant B.1.351 easily escapes Sputnik vaccine

A new preprint research paper posted to the medRxiv* server reports on vaccine resistance data that pushes the end of the pandemic further away.

New nanoparticle SARS-CoV-2 vaccine confers robust protection with single dose after two weeks

In a methodologically ‘state-of-the-art’ approach, US researchers have developed a protein-based nanoparticle vaccine against coronavirus disease (COVID-19), with a swift generation of antibodies and the potential to protect individuals who cannot receive other COVID-19 vaccines for medical reasons. The research is posted to the bioRxiv* preprint server.

Can universal vaccines and treatments against future SARS-CoV-2 variants be developed?

A team of researchers from Saudi Arabia and Spain recently quantified the rapid evolution of SARS-CoV-2 by tracking the mutations of the virus globally, focusing on the receptor-binding domain (RBD) of the virus’s spike protein, which determines its infectivity.

Researchers Identify potent small molecule inhibitors against SARS-CoV-2

A team of scientists from the USA and Sweden has recently screened 8 million small molecule inhibitors against SARS-CoV-2.

The use of mammalian cell surface display for rapid characterization of SARS-CoV-2 variants

A research group from the U.S. demonstrated the practicality of a spike display system in order to accelerate vaccine design, but also to swiftly appraise the effects of mutations in emerging strains of the SARS-CoV-2.

RNA-binding cylinders inhibit SARS-CoV-2 replication in vitro

Research led by Michael J. Hannon from the University of Birmingham, UK, finds metallo-supramolecular helicates (cylinders) binding to untranslated regions of SARS-CoV-2 suppresses viral replication. The untranslated regions (UTR) of the viral genome could serve as drug targets for antiviral treatment.

Chronic cannabis use associated with higher complication rates after spine surgery

For patients undergoing spinal surgery, the diagnosis of cannabis use disorder is associated with higher complication rates, including substantially increased risks of stroke and respiratory complications, reports a study in Spine.

Research offers new clues about the underlying mechanisms of itch

Eczema, or atopic dermatitis (AD), is sometimes called "the itch that rashes." Often, the itch begins before the rash appears, and, in many cases, the itchiness of the skin condition never really goes away.

Material deprivation is driving Covid-19 disparities among ethnic minority groups

Deprivation among society at large is 'driving' Covid-19 disparities among minority ethnic groups - predominantly South Asian and Black African or Caribbean populations - and could be considered the main cause of disproportionate infection rates, hospitalization and deaths experienced by these populations, according to new analysis from the University of Leicester.

Scientists identify nine potential new COVID-19 treatments

A team led by scientists in the Perelman School of Medicine at the University of Pennsylvania has identified nine potential new COVID-19 treatments, including three that are already approved by the Food and Drug Administration (FDA) for treating other diseases.
