War of sugars - estrogen provides protection in COVID-19

Now a new study published on the preprint server bioRxiv in July 2020 reports that sex hormones could affect the function of the fusion protein that is dependent upon the human ACE2 receptor, thus preventing the entry of the virus into the host cell.

Researchers report a liquid biopsy for COVID-19

A new study published on the preprint server medRxiv in July 2020 reports the potential of cell-free DNA as a marker of the severity of disease in COVID-19. This could help triage patients as well as provide a prognostic marker.

Researcher uses in silico analysis of SARS-CoV-2 spike protein to fast-track passive immunity

With millions of COVID-19 cases reported across the globe, people are turning to antibody tests to find out whether they have been exposed to the coronavirus that causes the disease. But what are antibodies? Why are they important? If we have them, are we immune to COVID-19? And if not, why not?

From swab to sequencing - scalable method for identifying SARS-CoV-2

A research group headed by Stanford University scientists has developed a scalable, high throughput method to generate high fidelity whole genome and HLA sequencing, viral genomes, and representation of human transcriptome from single nasopharyngeal swabs of coronavirus disease (COVID19) patients. Their results are published on the medRxiv preprint server.

Smoking worsens COVID-19 severity, warn researchers

A study conducted by researchers at the University of California, Los Angeles, suggests that smoking increases the risk of more severe lung disease in cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Scientists develop human lung organoids to study SARS-CoV-2 infection

Now, a new study published on the preprint server bioRxiv in July 2020 reports the development of a human distal lung culture system that can be functionally tested. This will help not only to understand how this infection produces disease but also to test the proliferative capacity of the stem cells in this part of the body.

Study reports highly potent anti-SARS-CoV-2 compounds

A new study published on the preprint server bioRxiv in July 2020 reports that a series of potent enzyme inhibitors have been designed to suppress severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication by interfering with one of the primary viral proteases.

Anti-inflammatory Tetracycline activity may modulate COVID-19 severity

The current COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), seems to attack the human airway epithelium primarily. In severely affected patients, the illness progresses to hypoxemic respiratory failure and acute respiratory distress syndrome (ARDS). The latter is treatable mainly by supportive management.

Antimalarial drug shows in vitro activity against SARS-CoV-2 and flu viruses

Now, a new study published in the preprint server bioRxiv in July 2020 reports on the antiviral activity of two drugs found in an antimalarial drug currently in phase II trials in South Korea, called Pyramax.

Study finds synthetic neutralizing/enhancing antibodies to SARS-CoV-2

A new study published on the preprint server bioRxiv in July 2020 reports the discovery of some antibody molecules that have powerful enhancing or neutralizing activity against the virus, in a library of synthetic antibodies. These hold the promise of being useful for the prevention or treatment of this illness.

Relatives of SARS-CoV-2 may pose a health threat for years to come

Coronaviruses are zoonotic viruses that jump from animals to humans and cause infection. There are many types of common human coronaviruses, which usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. Most people get infected with one or more of coronavirus types 229E, NL63, OC43, and HKU1 at some point in their lives.

The toll that COVID-19 takes on the heart

Now, two new studies describe the toll that COVID-19 takes in the heart, increasing the risk of long-term damage even after patients recover. These studies also show that heart damage can even occur in people who did not have severe illness that required hospitalization.

Loss of smell in COVID-19 explained by scientists

Now, a team of researchers at Harvard Medical school says they have found the reason why some people who get COVID-19 experience loss of smell.

Iota-carrageenan from red seaweed inhibits SARS-CoV-2 in laboratory conditions

In a recent bioRxiv paper, a research group from the Marinomed Biotech biopharmaceutical company in Austria showed that a sulfated polysaccharide iota-carrageenan has the propensity to inhibit cell entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by using an in vitro neutralization assay.

People with SARS-CoV-2 most infectious in days 0-5, no evidence of transmission after day 9

A study conducted by researchers in the UK and Italy suggests that individuals with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are probably at their most infectious during the first week of illness.

Inconsistent SARS-CoV-2 antibody results in nephrology workers

Using a broad spectrum of antibody tests the present study revealed inconsistent results for SARS-CoV-2 seroprevalence among asymptomatic individuals, while this was not the case among Covid-19 patients.

29 Jul 2020

Platelet hyperreactivity, a unique feature of COVID-19

A new study by Irish researchers and published in the preprint server medRxiv in July 2020 reports a bidirectional relationship between COVID-19 and coagulation abnormalities.

Exciting cost-effective SARS-CoV-2 vaccine candidate using Newcastle disease

Experts warn that the world may see repeated waves of the COVID-19 pandemic. However, scientists around the world are working hard to create a protective vaccine or antiviral, which could help to reduce the number of deaths and cases the next time around.

Case Fatality Rate alone may be a misleading measure of overall COVID-19 mortality

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected over 16.67 million individuals and caused over 659,000 deaths around the world. Commonly the deadly virus and its impact are measured by the case fatality ratio (CFR).

Mental health problems peak alongside COVID-19 in Australia

A new study has found that during the peak of the outbreak in Australia, the rates of psychological distress, anxiety, and depression symptoms rose among adults. The study is published in the latest issue of the journal PLOS ONE.
