Delta cutting ‘like a buzzsaw’ through Oregon-California border counties

If you live in one of the rural communities tucked into the forested hillsides along the Oregon-California border and need serious medical care, you'll probably wind up at Asante Rogue Regional Medical Center. It serves about nine counties on either side of the border.

The tale of mRNA vaccines: Turning calamity into opportunity

In a review paper published in the journal Nature Reviews, researchers from Carnegie Mellon University and the University of Pennsylvania have described the underlying technologies for mRNA vaccines and their future prospects with improved delivery systems and applications in diseases beyond the ongoing COVID-19 pandemic.

Study uses novel statistical approaches to identify factors that contributed to COVID-19 mortality

Staying home and limiting local travel, supporting access to primary care, and limiting contacts in contagion hubs - including hospitals, schools, and workplaces - are strategies that might help reduce COVID-19-related deaths, according to new research. The research team, by statisticians at Penn State, the Sant'Anna School of Advanced Studies in Pisa, Italy, and Université Laval in Quebec, Canada, used novel statistical approaches to compare the first wave of the epidemic across 20 regions in Italy and identify factors that contributed to mortality.

Durability of cellular immune memory to SARS-CoV-2 after mRNA vaccination

A recent study, available on the bioRxiv* preprint server, investigated the durability of cellular immune memory after mRNA vaccination against SARS-CoV-2 and whether booster jabs affect the durability of different immune response components. The study included testing for antibodies and cellular immune responses in covid patients and recovered individuals.

Science advisors gather in an international call for evidence-based policy making

The largest-ever independent gathering of interest groups, thought-leaders, science advisors to governments and global institutions, researchers, academics, communicators and diplomats is taking place in Montreal and online.

SARS-CoV-2 animal origin: What we know so far

Scientists at the University of Glasgow Centre for Virus Research in the United Kingdom and the South China Agricultural University in Guangzhou, China, have shed light on the animal origin of SARS-CoV-2, tracing back to the first outbreak of the severe acute respiratory syndrome coronavirus (SARS-CoV), the infectious agent of the severe acute respiratory syndrome (SARS) in China in 2002 to 2003.

Scientists identify potential biomarkers to predict COVID-19 outcomes

A team of scientists from the United States has recently examined the trajectory of early immune biomarkers in response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. They have identified specific plasma proteins that can accurately predict the clinical and virological outcomes in SARS-CoV-2 infected patients. The study is currently available on the medRxiv* preprint server.

Role of glycans on the SARS-CoV-2 spike protein in human receptor interaction

A team of investigators, led by Dr. Benjamin F. Mann, from Merck, USA have published a new study on the preprint server bioRxiv*. They have used a biochemical approach to control the glycosylation profile of the S protein receptor-binding domain (RBD) and to analyze the effect of different glycosylation patterns on receptor binding.

COVID-19 vaccine elicits antibody responses in nearly 9 out of 10 people taking immunosuppressants

COVID-19 vaccination elicited antibody responses in nearly nine out of 10 people with weakened immune systems, although their responses were only about one-third as strong as those mounted by healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.

Computational study identifies human proteins structurally similar to SARS-CoV-2 proteins

A new study published in Scientific Reports identifies the human proteins that share structural similarities with the SARS-CoV-2 proteins.

How early interferon curbs SARS-CoV-2 infection

A new study available in the Journal of Experimental Medicine focuses on the importance of interferon in SARS-CoV-2 infection.

Prevalence of vaccine breakthrough cases in SF Bay Area

A new study focuse on studying breakthrough infections in a highly vaccinated community owing to the emergence of SARS-CoV-2 variants.

Researchers study the role of low-density granulocytes in COVID-19

Information on granulocytes helps to understand mechanisms associated with covid-19 and other infectious diseases. Such information also promotes the development of better diagnostic methods and therapies.

Will mRNA vaccine boosters be required for SARS-CoV-2 variants?

A new study shows that the highly effective mRNA Moderna vaccine designed against the original SARS-CoV-2 strain may lose some efficacy as new variants arise.

Sustained and effective response to Janssen COVID-19 vaccine Is enhanced by delayed booster

A new study adds to the data on the optimum interval between the first and second doses of the adenovirus vectored COVID-19 vaccine.

Can SARS-CoV-2 be transmitted in the food cold chain?

A new study reports that the risk of transmitting SARS-CoV-2 through such fomites is very low.

Development of extra protective broad-spectrum antimicrobial face shield

In a new study available on the preprint server Preprints*, researchers have innovated a transparent face shield with intrinsic antimicrobial activity.

Could genetic variants in host cell receptors (ACE2) explain COVID-19 susceptibility among certain ethnic groups?

Led by Ioannis Karakikes of Stanford University, a new study suggests some hospitalized patients with COVID-19 contain ACE2 genetic variants that increase ACE2 expression. Some variants that altered ACE2 protein expression and binding affinity were more prevalent in people with European backgrounds.

CoronaVac elicits lower antibody response than natural SARS-CoV-2 infection, study suggests

A recent study from Thailand highlights a rather low degree of neutralization-afforded protection mounted by the inactivated whole-virus CoronaVac vaccine compared to natural infection with SARS-CoV-2 – the virus that causes COVID-19.

30 Aug 2021

New study maps the evolution of the SARS-CoV-2 delta and delta plus variants

The SARS-CoV-2 delta variant bears the D164G mutation, which is known to enhance viral fitness. However, a number of additional mutations are known to be common to the delta and delta plus lineages, at least 25 as identified in a study recently published in the Journal of Autoimmunity, mainly located on the spike protein of the virus.
