VUMC receives $34 million grant for nationwide convalescent plasma study

Vanderbilt University Medical Center has been awarded a one-year, $34-million grant by the National Center for Advancing Translational Sciences, part of the National Institutes of Health, to conduct a nationwide study of "convalescent plasma" as a treatment for COVID-19.

Study: Many COVID-19 patients suffer cardiovascular damage even after recovery

One of the most harrowing effects of COVID-19 is severe damage to the lungs, which makes breathing hard or impossible for those who're severely affected.

DeSantis says COVID is a lower risk for school-aged kids than flu

Even as his state is a hotbed for COVID-19, Florida Gov. Ron DeSantis has been pushing schools to reopen so parents have the choice of sending children back to the classroom or keeping them home to learn virtually.

SARS-CoV-2 ORF9c responsible for immune evasion and efficient infection of host

A recent study by researchers at the Sanford Burnham Prebys Medical Discovery Institute and the University of California San Francisco and published on the preprint server bioRxiv in August 2020 shows that a protein encoded by the subgenomic sequence ORF9c of SARS-CoV-2 is responsible for the low antiviral response in infected humans, enabling the successful replication of the virus in the host.

AnteoTech's COVID-19 antigen and Flu A&B test detects SARS-Cov-2, influenza in less than 15 minutes

AnteoTech Ltd has successfully developed proof-of-concept COVID-19 antigen and Flu A&B point-of-care lateral flow tests that can detect the presence of SARS-Cov-2 and influenza in less than 15 minutes.

Macaques show low neutralizing antibody and cellular immune response to SARS-CoV-2

A new study published on the preprint server bioRxiv* in August 2020 presents a cynomolgus macaque model that develops symptomatic SARS-CoV-2 infection in a mild form, with low or no antibody responses, making it suitable to study human responses to vaccines and drugs targeting the virus.

Researchers compare COVID-19 transmission risk when singing, speaking and breathing

Now, a new study* set to determine if singing and playing of woodwind and brass instruments produce more respiratory droplets and aerosols than speaking. Further, they want to know if the size and temperature of the venue will make a difference in the accumulation of aerosol droplets in the air.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

No evidence of active SARS-CoV-2 in breastmilk of infected women

A recent study published in the journal JAMA in August 2020 suggests that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for infants.

Study evaluates the reliability of new serological assays for detecting SARS-CoV-2 antibodies

Approximately four months after the initial description of cases of atypical pneumonia in Wuhan, China, in December 2019, COVID-19 had become a major pandemic threat.

Websites selling home-based COVID-19 testing kits providing inadequate or misleading information

In the UK and US, many websites are selling direct to user self-sampling and testing kits to detect SARS-CoV-2. Recently, a cross-sectional observational study was carried out to check the completeness and accuracy of information provided by these websites.

Fewer rhinovirus infections in Philadelphia after COVID-19 stay-at-home orders

Philadelphia and its surrounding counties issued a series of "stay-at-home" orders on March 17, 2020 in an effort to curb the spread of COVID-19.

New SARS-CoV-2 vaccine effective in macaques

Researchers from the biotechnology company Novavax in Gaithersburg, Maryland, have developed a vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that successfully induces immunogenicity and protection against the virus in macaques.

COVID-19 could compromise key element of immune response

Researchers at the University of Melbourne have made the unsettling discovery that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might compromise the activation of the CD8+ T-cell responses that would usually ameliorate disease and drive recovery in cases of respiratory disease.

Whey protein from human breastmilk inhibits SARS-CoV-2 infection

Many scientists have reported the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on pregnancy and the virus has been detected in breastmilk. Now a new study published on the preprint server bioRxiv* in August 2020 shows that whey protein in human breastmilk efficiently prevents infection with SARS-CoV-2 as well as post-entry viral replication.

Low indoor air humidity increases spread of SARS-CoV-2

The airborne transmission of the coronavirus SARS-CoV-2 via aerosol particles in indoor environment seems to be strongly influenced by relative humidity.

Cells lining the nose are key entry point for coronavirus, shows study

Scientists at Johns Hopkins Medicine, experimenting with a small number of human cell samples, report that the "hook" of cells used by SARS-CoV-2 to latch onto and infect cells is up to 700 times more prevalent in the olfactory supporting cells lining the inside of the upper part of the nose than in the lining cells of the rest of the nose and windpipe that leads to the lungs.
