How COVID-19 highlights the uncertainty of medical testing

Dr. Jacqueline Chu considered the man with a negative coronavirus test on the other end of the phone, and knew, her heart dropping, that the test result was not enough to clear him for work.

Machine learning model identifies which drug combinations kill tumor cells

When healthcare professionals treat patients suffering from advanced cancers, they usually need to use a combination of different therapies. In addition to cancer surgery, the patients are often treated with radiation therapy, medication, or both.

SARS-CoV-2's microRNAs may have promoted its jump to humans

A new study uses machine learning to explore the small microRNAs (or miRNAs) of SARS-CoV-2 that may determine the virus's ability to successfully infect humans by altering the course of transcriptional events.

Chinese woman still sheds SARS-CoV-2 over four months post-infection

A new study by Chinese scientists explore an unusual case of extended viral shedding in a 68-year-old woman up to four months post-infection.

COVID-19 restrictions have led to 86 percent drop in norovirus infections in US, finds study

The onset of the COVID-19 pandemic led to the imposition of several non-pharmaceutical interventions (NPIs) across the world. While citizens in the USA have been chafing over the advice to wear masks in public, restricted social interactions, and limited attendance at schools, colleges and workplaces, a new study published on the preprint server medRxiv* in November 2020 reports that these NPIs were linked to a steep reduction in the incidence of the non-respiratory pathogen, noroviruses.

Low endorsement among doctors worldwide for COVID-19 ‘immunity passports’

A cross-sectional survey conducted in September 2020, aimed at assessing the views of a randomly selected, stratified physician sample on this matter, drawing names from physicians registered with the global networking platform called Sermo. This offers its registration service to verified licensed physicians.

Experts urge governments to rethink COVID-19 infection control policies for schools

An urgent rethink of infection control policies to keep COVID-19 infection at bay in schools is needed if primary schools are to be kept open this winter, and the knock-on effects on their families avoided, argue children's infectious disease specialists in a viewpoint, published online in the Archives of Disease in Childhood.

Nucleic acid-hydrolyzing scFv 3D8 exhibits potent antiviral effects on SARS-CoV-2

3D8, a 27-kDa recombinant antibody fragment, was found in autoimmune-prone Murphy Roths Large mice. The single-chain variable fragment (scFv) has the nucleic acid hydrolyzing activity and is shown to degrade DNA or mRNA of viruses in infected cells.

Fibromyalgia during COVID-19, anxiety and pain

Early research on the impact of the COVID-19 pandemic found persistent related anxiety in the general population. Researchers in the UK hypothesized that this anxiety would be associated with increased pain in chronic pain patients diagnosed with fibromyalgia (FM).

Good cholesterol helps SARS-CoV-2 enter cells

The researchers explained that the SARS-CoV-2 can infect human host cells after its viral spike protein (SARS-2-S) binds to a cellular surface receptor called the angiotensin-converting enzyme 2 (ACE2).

Clonal hematopoiesis linked to severe COVID-19

Now, an international team of researchers from the USA, South Korea and Canada has found that clonal hematopoiesis is tied to the risk of severe COVID-19.

Infection control, widespread testing help reduce SARS-CoV-2 transmission in schools, study finds

Now, a team of researchers at the New York University Grossman School of Medicine explored which school policies had the most significant impact on reducing the risk of in-school SARS-CoV-2 transmission.

Researchers reveal how SARS-CoV-2 reaches the brain

Using post-mortem tissue samples, a team of researchers from Charité - Universitätsmedizin Berlin have studied the mechanisms by which the novel coronavirus can reach the brains of patients with COVID-19, and how the immune system responds to the virus once it does.

Chemical compounds in foods can block the function of key SARS-CoV-2 enzyme

Chemical compounds in foods or beverages like green tea, muscadine grapes and dark chocolate can bind to and block the function of a particular enzyme, or protease, in the SARS-CoV-2 virus, according to a new study by plant biologists at North Carolina State University.

Memory B cells persist in recovered COVID-19 patients

A team of scientists from the University of Washington, USA, and the Karolinska Institute, Sweden, has comprehensively studied the antibody-mediated immune responses in patients diagnosed with coronavirus disease 2019 (COVID-19).

SARS-CoV-2 immunity in the U.S. remains low

Seroprevalence studies indicate that less than 10% of people in the U. S. have detectable antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from July to September 2020.

A mutant SARS-CoV-2 subspecies from minks may evade antibody detection

In a recent research letter published on the bioRxiv preprint server, scientists from Japan discovered that the mutation of spike glycoprotein in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) derived from farmed minks can also be found in the group of individuals with coronavirus disease (COVID-19) and subsequently evade detection by our immune system.
