With Covid-19 dominating medical science and human concern, chemists at the University of Sydney have developed a method to quickly and safely synthesise protein vaccines for respiratory diseases for pre-clinical tests. Their approach can be used to test vaccine strategies against novel pandemic pathogens such as SARS-CoV-2, the virus that causes Covid-19.
One of the most vexing aspects of the Covid-19 pandemic is doctors’ inability to predict which newly hospitalized patients will go on to develop severe disease, including complications that require the insertion of a breathing tube, kidney dialysis or other intensive care. Knowledge of a patient’s age and underlying medical conditions can help predict such outcomes, but there are still…
According to current studies, the Covid-19 disease which is caused by the SARS-CoV-2 coronavirus comprises at least five different variants. These differ in how the immune system responds to the infection. Researchers from the German Center for Neurodegenerative Diseases (DZNE) and the University of Bonn, together with other experts from Germany, Greece and the Netherlands, present these findings…
Scientists at The Ohio State University have discovered a new variant of SARS-Cov-2, the virus that causes Covid-19. The new variant carries a mutation identical to the U.K. strain, but it likely arose in a virus strain already present in the United States. The College of Medicine researchers also report the evolution of another U.S. strain that acquired three other gene mutations not previously…
Researchers at Karolinska Institutet have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells. The research study, published in Science, shows that a combined nanobody had a particularly good effect – even if the virus mutated. According to the researchers, the…

Bacteria or viruses like influenza that cause pneumonia can spread across large regions of the lung within hours. In the modern intensive care unit, these bacteria or viruses are usually controlled either by antibiotics or by the body’s immune system within the first few days of the illness. But in a study published in Nature, investigators at Northwestern Medicine show Covid-19 pneumonia is…
Researchers at the University of Chicago have created the first usable computational model of the entire virus responsible for Covid-19—and they are making this model widely available to help advance research during the pandemic. “If you can understand how a virus works, that’s the first step towards stopping it,” said Prof. Gregory Voth, whose team created the model published in…
Even those who understand the scientific process, trust medical experts and know how important vaccines are for fighting infectious diseases might still have some questions or concerns about the new Covid-19 vaccines. Here, Thaddeus Stappenbeck, MD, PhD, helps set the record straight on 8 common questions, concerns and myths that have emerged about Covid-19 vaccines.
The variety and volume of bacteria in the gut, known as the microbiome, may influence the severity of Covid-19 as well as the magnitude of the immune system response to the infection, suggests research published online in the journal Gut. Imbalances in the make-up of the microbiome may also be implicated in persisting inflammatory symptoms, dubbed ‘long Covid’, the findings suggest. Covid-19…
In some cases, immune cells in the lungs can contribute to worsening a virus attack. In a new study, researchers at Karolinska Institutet describe how different kinds of immune cells, called macrophages, develop in the lungs and which of them may be behind severe lung diseases. The study, which was published in Immunity, may contribute to future treatments for Covid-19, among other diseases.
So far, little research has been done on the risk of children being seriously affected by Covid-19 when the schools were open. A study from Karolinska Institutet has now shown that one child in 130,000 was treated in an intensive care unit on account of Covid-19 during the period March-June. The study has been published in New England Journal of Medicine.
Before the pandemic, the lab of Stanford University biochemist Peter S. Kim focused on developing vaccines for HIV, Ebola and pandemic influenza. But, within days of closing their campus lab space as part of Covid-19 precautions, they turned their attention to a vaccine for SARS-CoV-2, the virus that causes Covid-19. Although the coronavirus was outside the lab’s specific area of expertise,…
Patients with acute heart failure nearly double their risk of dying if they get Covid-19, according to new research. The small, single centre study highlights the need for patients with heart failure to take extra precautions to avoid catching Covid-19. “Our results support prioritising heart failure patients for Covid-19 vaccination once it is available,” said study lead investigator Dr.…
The Corona pandemic poses new challenges for health care facilities as well as manufacturers of health IT and medical technology. Marcel Herrmann, Marketing Manager Medical Imaging at JVCKenwood, explains in an interview what these are and how they can be solved.
ZTA Biotech, a Budapest-based biotech startup, has developed a Covid-19 antibody (IgG) test using the ELISA protocol. This new detection method represents a great step forward in determining if patients have had a coronavirus infection and if they might still have immunity to the disease. Early results have proven 100% in specificity after testing 280 samples, and 100% sensitivity by testing 260…
Reports from Imperial College regarding the spread and the effects of Covid-19 had considerable policy impacts in several European countries. But the models that informed the reports have considerable flaws, and are not sufficient to draw the conclusions that were published. This is according to researchers from universities including Linköping University (LiU), in an article in Nature.
The search for antiviral agents against the new coronavirus is in full swing. Using a novel approach, Bioinformaticians have now discovered a weakness in the virus that could be exploited for drug development. In a computer model, the scientists discovered a human enzyme that is crucial for the virus. When it was switched off in the model, the virus could no longer multiply.
