Research suggests New York City may have reached coronavirus herd immunity threshold

A new study by researchers at University of Illinois at Urbana-Champaign and Brookhaven National Laboratory and published on the preprint server medRxiv in July 2020 discusses the effect of a factor called persistent contact heterogeneity on the final epidemic size of COVID-19.

Mandatory BCG vaccination correlates with flattening of the curve in COVID-19 spread

Scientists have found that countries with mandatory Bacillus Calmette-Guérin (BCG) vaccination until at least the year 2000 tended to exhibit slower infection and death rates during the first 30 days of the outbreak of COVID-19 in their country.

UOttawa's Faculty of Medicine awards 58 clinical research chairs to top clinician-scientists

The Faculty of Medicine has awarded 58 clinical research chairs to top clinician-scientists in a five-year, $40 million investment to drive clinical research excellence and enhance health and patient care.

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?

Multiple, intertwined cell death systems to prevent the spread of 'intracellular' bacteria

Melbourne researchers have revealed the multiple, intertwined cell death systems that prevent the spread of the 'intracellular' bacterium Salmonella, an important cause of typhoid fever which kills more than 100,000 people annually.

Study shows how chronic psychological stress leads to sickle cell crises

A new study shows how chronic psychological stress leads to painful vessel-clogging episodes--the most common complication of sickle-cell disease (SCD) and a frequent cause of hospitalizations.

Immunosuppressive steroids help tumors to evade the immune system

A new study has revealed that tumors can evade the immune system by telling immune cells to produce immunosuppressive steroids.

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.

Study identifies potential drug targets for developing new cancer immunotherapies

A study has revealed that tumours can evade the immune system by telling immune cells to produce immunosuppressive steroids.

New test rapidly determines neutralizing antibodies against Sars-Cov-2

To determine immunity to Sars-Cov-2 and the effectiveness of potential vaccines, the amount of neutralizing antibodies in the blood of recovered or vaccinated individuals must be determined.

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.

Medieval medicine to tackle antibiotic resistance

Biofilm-associated infections are notoriously difficult to treat, and they also play a role in antibiotic resistance as more antimicrobials are urgently needed to treat biofilm-associated infections. These biofilms act as protective layers that prevent the antibiotics from reaching and destroying the targeted bacteria.

Clinical study evaluates potential of oral cancer drug to reduce respiratory symptoms of COVID-19

Researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute and The Ohio State University Wexner Medical Center are conducting a new clinical trial to determine if an oral cancer drug called ibrutinib can also help patients with cancer or other immunocompromised conditions recover from COVID-19.

29 Jul 2020

Study explores if prior exposure to common cold viruses may affect SARS-CoV-2 severity

A study led by Charité - Universitätsmedizin Berlin and the Max Planck Institute for Molecular Genetics (MPIMG) shows that some healthy individuals possess immune cells capable of recognizing the novel coronavirus, SARS-CoV-2.

Waterloo tech profiles antibodies in blood of COVID-19 patients

A world-leading University of Waterloo spinoff company, that decodes blood samples for potential treatments for illnesses like cancer and COVID-19, is expanding operations with the help of a $5-million USD investment.

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.

Recurrent SARS-CoV-2 positives not infectious in discharged COVID-19 patients, says Chinese study

A new research paper from China published on the preprint server medRxiv* claims that recurrent positive results for SARS-CoV-2 are due to the presence of low levels of viral RNA fragments and not the shedding of infectious virus particles.

Researchers unlock new insights that may help inform vaccine design for infectious diseases

Vaccination is the most effective public health measure to prevent infectious diseases. Vaccines can greatly reduce the risk of infection by working with the body's natural defenses to safely develop immunity to disease.

Study reveals new mechanism that fuels cancer adaptation

Collaborative Cancer Research UK-funded studies from University of Oxford researchers have uncovered a new mechanism by which cancer cells adapt to the stresses they encounter as they grow and respond to therapies.

Human genome may explain the neonatal origins of chronic immune and inflammatory diseases

A study published in the journal Nature Communications has pinpointed a number of areas of the human genome that may help explain the neonatal origins of chronic immune and inflammatory diseases of later life, including type 1 diabetes, rheumatoid arthritis and coeliac disease.
