Study focuses on COVID-19 patients with inflammatory rheumatic diseases

The ongoing COVID-19 pandemic has caused nearly five million cases and over 327,000 deaths worldwide. The signs and symptoms of this disease are varied, although there are typical features which assist diagnosis.

Study shows engineered SARS-CoV-2 spike protein may be utilized for vaccine development

In a new study available on the preprint server bioRxiv, researchers demonstrate how the conformation of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S-protein) can be controlled with the rational construct design, providing a framework for S-protein structure engineering in vaccine/drug development.

Certain corticosteroid could improve severe COVID-19, say researchers

Researchers at Wayne State University and Henry Ford Health System in Michigan have conducted a study indicating that the corticosteroid methylprednisolone could improve outcomes among patients with severe coronavirus disease 2019 (COVID-19).

Moderna’s coronavirus vaccine candidate shows promise in phase I trial

Moderna, who partnered with the National Institutes of Health, announced that its candidate vaccine appeared to be safe when administered to eight healthy volunteers. The vaccine also stimulated an immune response to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19).

Does COVID-19 infect peripheral blood cells?

The emergence of the novel coronavirus outbreak in December 2019 was followed by its spread on a global scale unparalleled in the last 100 years. At present, it has claimed over 322,000 lives the world over, with over 4.88 million cases having tested positive.

Did SARS-CoV-2 adapt to humans long before the index case?

A new study from Canada and the U.S. suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have already been pre-adapted to human transmission when it emerged in late 2019, which means there may be lingering populations of progenitor SARS-CoV-2 adept for human transmission and coronavirus disease (COVID-19) re-emergence. The research is published on the preprint server bioRxiv in May 2020.

X-ray experiments demonstrate a new way to block the entry of SARS-CoV-2

As scientists across the globe race to develop a vaccine against SARS-CoV-2, the coronavirus that causes COVID-19, an international team led by Davide Corti at Vir Biotechnology and David Veesler at the University of Washington has been working around the clock on a complementary approach - identifying neutralizing antibodies that could be used as a preventative treatment or as a post-exposure therapy.

New animal model for COVID-19

As the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to ravage the world, scientists are frantically searching for a vaccine or new drug that will effectively counter the lethal effects of the virus that leads to COVID-19 disease.

Potential new treatment approach to fatal COVID-19

Researchers from the University of Colorado Anschutz Medical Campus and Pathways Bioscience in the United States have found that activating a transcription factor involved in oxidative stress regulation, antiviral activity, and inflammation may serve as a new treatment approach to coronavirus disease 2019 (COVID-19).

Novel insights on SARS-CoV-2 cell entry may inform further vaccine and treatment development

A research group from Harvard Medical School reported two cryo-electron microscopy structures derived from a single preparation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) protein in their paper available on the preprint server bioRxiv. Understanding the nuances of prefusion and postfusion conformations shed light on viral cell entry and may, in turn, guide the development of vaccines and drugs.

Oxford University vaccine prevents SARS-CoV-2 pneumonia in rhesus macaques

As the world continues to grapple with the coronavirus pandemic, many scientists, institutions, and pharmaceutical companies are working hard to develop an effective vaccine.

Study shows broad geographic and evolutionary dispersal of betacoronaviruses from African bats

A research group from Nigeria found evidence of long-distance transmission and dispersal between bat coronaviruses isolated in Africa and the ones Europe and Asia, as described in a new paper available on the preprint server bioRxiv.

Hot temperatures, air pressure, UV radiation may decrease COVID-19 incidence

A new scientific paper published on the preprint server medRxiv shows that the spread of COVID-19, the respiratory illness that has spread across the world to kill hundreds of thousands in 2020, shows that weather conditions reduce the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Viral shedding among pre-symptomatic COVID-19 patients finds study

Researchers from Bangalore, India, have found that 68 percent of pre-symptomatic patients with COVID-19 may be shedding the virus and potentially infecting others. Their study titled, “Quantitative COVID-19 infectiousness estimate correlating with viral shedding and culturability suggests 68% pre-symptomatic transmissions,” was published on the open-access preprint server Medrxiv.

Genome-based monitoring of multi-resistant pathogen can help improve infection control

S. maltophilia strains occur in several natural and human associated ecosystems. The bacterium was long regarded as relatively unproblematic but is now considered to be one of the most feared hospital pathogens, as it frequently causes infections and is resistant to a number of antibiotics.

15 May 2020

New insights into SARS-CoV-2 viral diversity

The first comprehensive, large-scale analysis available on the preprint server bioRxiv attempted to identify specific genomic signatures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) strains within and across individual hosts – revealing recombination events, specific geographic profiles, as well as multi-strain and/or superinfections characteristic for the coronavirus disease (COVID-19) pandemic.

A 'window of vulnerability' for re-infection with HIV after stem cell transplantation

Some people with HIV need to undergo an allogeneic stem cell transplantation in order to treat different types of blood cancer. Most of the patient's immune cells are eliminated during these transplantations.

Modified tattoo electrodes can be used to measure brain activity

In 2015 Francesco Greco, head of the Laboratory of Applied Materials for Printed and Soft electronics (LAMPSe) at the Institute of Solid State Physics at Graz University of Technology, developed so-called "tattoo electrodes" together with Italian scientists.

Research reveals how long SARS-CoV-2 survives on surfaces, in feces and urine

A new study published on the preprint server medRxiv* in May 2020 shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease can remain viable for a maximum of one week on smooth environmental surfaces, for several hours in human feces, and for a maximum of 4 days in human urine. This knowledge could help guide disinfection policies to control the virus spread.
