Shark vNAR antibodies inhibit SARS-CoV-2 variants in vitro

Researchers in the UK and Austria have identified a novel class of antibodies that is highly effective at neutralizing the original strain of severe acute respiratory syndrome (SARS-CoV-2) and maintaining blocking activity against certain viral variants that have emerged.

Compound may block COVID-19 virus from entering lung cells, study reports

Research conducted at LSU Health New Orleans Neuroscience Center of Excellence reports that Elovanoids, bioactive chemical messengers made from omega-3 very-long-chain polyunsaturated fatty acids discovered by the Bazan lab in 2017, may block the virus that causes COVID-19 from entering cells and protect the air cells (alveoli) of the lung.

Innovative protocol that processes saliva samples before testing may improve COVID-19 detection

The collection of nasopharyngeal swab (NPS) samples for COVID-19 diagnostic testing poses challenges including exposure risk to healthcare workers and supply chain constraints. Saliva samples are easier to collect but can be mixed with mucus or blood, and some studies have found they produce less accurate results.

The longevity of SARS-CoV-2 antibodies and their cross-neutralization against variants of concern

In a new study by researchers in the UK, the activity of neutralizing antibodies collected from the sera of individuals that contracted COVID-19 during the first wave of the pandemic is tested against variants of concern the B.1.1.7 (or UK) variant and the B.1.351 (or South African) variant, demonstrating somewhat reduced potency of neutralization towards these strains.

Bovine-derived polyclonal antibodies exhibit high efficacy in neutralizing SARS-CoV-2 variants

A team of scientists in Estonia has recently evaluated the therapeutic/prophylactic efficacy of anti-SARS-CoV-2 polyclonal antibodies derived from the colostrum of immunized cows.

Is B.1.617.2 more transmissible than earlier SARS-CoV-2 variants?

A new study, released as a preprint on the medRxiv* server, reports that the B.1.617.2 variant is possibly more transmissible than earlier variants, based on the discovery that the serial intervals were not prolonged with this strain.

Are pre-existing Vitamin D deficiencies linked to COVID-19 severity and mortality?

Even as the COVID-19 pandemic continues to spread and new variants of SARS-CoV-2 emerge, much remains to be known about why severity varies so unpredictably between individuals. A new study, released as a preprint on the medRxiv* server, elucidates the relationship between Vitamin D and COVID-19 severity.

Could the COVID-19 vaccination rollout protect against future coronavirus outbreaks?

A new study suggests that the rollout of vaccines against the COVID-19 pandemic may be significant not only in preventing infections by SARS-CoV-2 but other endemic and pandemic-potential coronaviruses (CoVs) as well.

SARS-CoV-2 detection associates with viral RNA prevalence in patients and hospital environment

Watching what was happening around the world in early 2020, University of California San Diego School of Medicine researchers knew their region would likely soon be hit with a wave of patients with COVID-19, the infection caused by the coronavirus SARS-CoV-2.

Local anesthetic procaine inhibits SARS-CoV-2 in vitro

Research has shown that procaine and procaine-hydrochloride can reduce replication of SARS-CoV-2 and influenza A viruses in infected cells and reduce the production of cytokines by the viruses, making them potentially useful for treating COVID-19.

New article explains the pros and cons of nasal vaccines

Vaccines are mostly synonymous with needles, an efficient and effective way to provide immunity to myriad infections. As COVID-19 vaccination efforts roll out across the U.S. and the world, some experts believe that a vaccine administered through the nose could be just as effective and easier to administer.

Eldelumab and Fenofibrate show potential for COVID-19

In a new study posted to the medRxiv* preprint server, researchers from the University of Pittsburgh and Barrow Neurological Institute report the results of their analysis of several RNA-Seq studies and used computational approaches to discover potential drugs against COVID-19.

Study reports on the immunogenicity of single-shot COVID-19 vaccine against SARS-CoV-2 variants

In the three months since Johnson & Johnson's COVID-19 vaccine received emergency use authorization from the U.S. Food and Drug Administration, more than 10 million Americans have received the vaccine, according to the Centers for Disease Control and Prevention.

Trained dogs can accurately identify COVID-19 by scent

An interesting new medRxiv* preprint reveals that with careful training, the exquisite scent sensitivity of dogs may be exploited to rule out the presence of coronavirus disease 2019 (COVID-19) in human beings in real-time.

Review of COVID-19's long-term effects

In a recent study, Canadian researchers documented the prevalence of post-COVID-19 conditions 4-12 weeks (short-term) and >12 weeks (long-term), by conducting a systematic review of peer-reviewed literature. This work is posted to the medRxiv* preprint server.

Warmer conditions are not enough to prevent COVID-19 transmission, research shows

New research shows transmission of the virus behind COVID-19 varies seasonally, but warmer conditions are not enough to prevent transmission.

SARS-CoV-2 enzyme inhibitors among drugs screened for repurposing

A new bioRxiv* preprint describes the identification of some promising pharmaceutical compounds that could be developed as antiviral drugs against COVID-19.

DNA on-off switches for SARS-CoV-2 host receptor as potential therapeutic targets

Researchers in the United States and Canada have identified DNA on/off “switches” within the angiotensin-converting enzyme 2 (ACE2) gene that may control the expression of this host cell receptor before, during and after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Cold winter temperatures may accelerate spread of SARS-CoV-2

Writing in the journal Frontiers in Public Health, the team from Weifang Medical University said: “We believe that the low-temperature environment in winter may accelerate the spread of the outbreak and that new outbreaks may occur.”

Smoking and vaping increase ACE2 levels and virus spike binding in airway epithelium

A new bioRxiv preprint attempts to make some sense of why certain people experience more severe forms of COVID-19 as compared to others by pointing to the increase in virus binding that occurs in the presence of smoking or vaping.
