Picomolar inhibitors to SARS-CoV-2 proteins

Now, a new study published on the preprint server bioRxiv in August 2020 reports the development of mini-inhibitors based on computational design, that are suitable for such topical use.

Test, trace, isolate key to safe schools in COVID-19

Researchers led by Professor Kristine Maccartney from the National Centre for Immunization Research and surveillance, the Children's Hospital at Westmead and the University of Westmead, Australia explain that schools around the world have shut down to prevent the virus transmission.

Specifically designed cyclic peptide inhibitor shown to be active against SARS-CoV-2

A new bioRxiv study by a research group from the University of California Irvine shows in vitro activity and non-toxicity of the first-in-class cyclic peptide that inhibits the main protease of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – laying the groundwork for its use in the treatment of coronavirus disease (COVID-19).

Novel mutation identified in SARS-CoV-2 spike protein from Sweden

Researchers from Sweden and Brazil have identified a novel mutation in a strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) obtained from a patient in Stockholm, Sweden, in late April.

Regeneron antibody cocktail shows promise as potential COVID-19 treatment

Researchers in the U.S. have shown both preventive and treatment effects of an antibody cocktail in animal models of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) - the agent that causes coronavirus disease 2019 (COVID-19).

Yale researchers develop new mouse model to study SARS-CoV-2 infection

Researchers at Yale University School of Medicine have developed a new mouse model to study SARS-CoV-2 infection and disease and to accelerate testing of novel treatments and vaccines against the novel coronavirus.

Lower incidence of COVID-19 in high-altitude residents is intriguing, but requires more research

Despite recent reports of lower COVID-19 incidence among high-altitude populations, current data is insufficient to conclude that high altitude is protective against the SARS-CoV-2 virus, as reported in the peer-reviewed journal High Altitude Medicine & Biology.

Estrogen modestly protective against COVID-19?

Almost from the beginning, scientists have been struck by the disproportionately higher numbers of men and older adults who have developed severe COVID-19 disease compared to younger individuals and women. Prior research has shown that in 37 of the 38 countries from which sex-stratified data was available, males were at a higher risk of death. Also, post-menopausal women are at increased risk of severe COVID-19. However, the biological underpinnings of this have been less visible.

Five alternative methods of SARS-CoV-2 suppression

The current pandemic has proved to be challenging to control without stringent and comprehensive non-pharmacological interventions (NPIs), relying mostly on isolation and contact tracing of cases, along with social distancing. However, strategies like these have a huge human cost in terms of restriction of social interactions, resulting in depressive tendencies, disruption of economic activity, and loss of educational resources.

Zika virus mutation responsible for quick spread, birth defects uncovered

A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered a Zika virus mutation that may be responsible for the explosive viral transmission in 2015/2016 and for the cause of microcephaly (babies with small heads) born to infected pregnant women.

Study identifies possible therapeutic treatment for COVID-19

Yunjeong Kim and Kyeong-Ok "KC" Chang, virologists in the College of Veterinary Medicine at Kansas State University, have published a study showing a possible therapeutic treatment for COVID-19.

A new platform to provide information on SARS-CoV-2 immunity or seroprevalence

Who has overcome an infection with the virus without noticing, and how many people have already produced protective antibodies against the new coronavirus? Various antibody studies are now under way that will provide information on immunity or seroprevalence in the population.

Research explains recognized sex differences in COVID-19 outcomes

The COVID-19 pandemic has notably taken a more significant toll on men compared to women, in terms of both disease severity and death. Now, a new study by researchers at the Icahn School of Medicine at Mount Sinai and published on the preprint server medRxiv in August 2020 confirms the increased risk that males have for death following COVID-19 while also highlighting worse outcomes in women with coronary artery disease, obesity, and hypoxia compared to men.

Extensive study of SARS-CoV-2 sequencing reveals six strains of the virus

The virus causing the COVID-19 pandemic, SARS-CoV-2, presents at least six strains. Despite its mutations, the virus shows little variability, and this is good news for the researchers working on a viable vaccine.

Study shows high SARS-CoV-2 seroprevalence, but low death rate in Malawi's health care workers

A study by researchers from Malawi and United Kingdom reveals a significant discrepancy between predicted coronavirus disease (COVID-19) mortality in the observed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) seroprevalence rates in health care workers and reported deaths in urban Malawi in southeastern Africa, indicating early exposure, but a slow progression of the outbreak. Their findings are currently available on the medRxiv preprint server.

SARS-CoV-2 lured away and trapped by a new decoy version of ACE2

Researchers in the United States and Canada have engineered affinity-optimized “receptor traps” that prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from binding to and infecting cells.

Novel short ACE2 isoform may influence SARS-CoV-2 susceptibility

A study led by researchers at the University of Southampton, UK, has identified a novel short isoform of the full-length receptor that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses to gain entry to host cells.

Cloth face masks have potential to reduce the transmission of SARS-CoV-2 viruses

A literature review coordinated by Karolinska Institutet in Sweden and McMaster University in Canada demonstrates that cloth face masks provide clinically useful levels of filtration, which has the potential to reduce the spread of viruses such as SARS-CoV-2.

Oxford Nanopore Technologies partners with UK Government to roll out LamPORE, a new generation of COVID-19 test

Oxford Nanopore today announces an agreement with the UK’s Department of Health and Social Care, to roll out its novel LamPORE test.

Photonics-based device could help COVID-19 patients with adequate treatments

Few could have foreseen the considerable impact that SARS-CoV-2 has had so far and is still having worldwide. Numbers continue to escalate and the complexity of the COVID-19 symptoms have hindered all efforts to optimize its treatment.
