A platform for studying how the human immune system responds to hepatitis C infection by combining microfluidic technology with liver organoids could speed the hunt for a vaccine.
COVID-19 measures such as school closures and ‘high-traffic and mixing’ areas had the strongest association, providing clues for new intervention approaches.
The tool has made it possible to detect SARS-CoV-2 in exudate from symptomatic patients with a sensitivity of 100% and a specificity of 87.5%
Scientists have confirmed that an inhaled form of COVID vaccine can provide broad, long-lasting protection against the original strain of SARS-CoV-2 and variants of concern.
Researchers have developed an inexpensive, non-toxic coating for almost any fabric that decreases the infectivity of the virus that causes COVID-19 by up to 90 per cent.
Scientists have investigated the effectiveness of various common hand disinfectants against hepatitis E. They were able to show that most formulations do not completely inactivate the virus.
Researchers have developed a device that removes one of the biggest bottlenecks preventing quick, reliable malaria diagnosis.
A connection between the Epstein-Barr virus and multiple sclerosis has long been suspected. A new study provides ‘compelling evidence of causality’.
In both the mice and organoids, cytokines suppressed tumor growth after treatment, and defense cells migrated to the brain region affected by the tumor, alerting the immune system to its existence.
Researchers have developed a diagnostic for SARS-CoV-2 that is capable of differentiating between COVID-19 and the garden-variety bug with fast turnaround.
Scientists at have designed a quantum sensor to detect SARS-CoV-2 faster, cheaper, and more accurate than the current gold-standard technique, PCR.
An international team of scientists have identified antibodies that neutralize omicron and other SARS-CoV-2 variants.
In experiments using saliva samples from COVID-19 patients, the gum, which contains the ACE2 protein, neutralized the virus.
A new rapid molecular diagnostic test from Cepheid has received the CE mark for distribution in the European market. The test, called Xpert Xpress CoV-2/Flu/RSV plus, is designed for qualitative detection of the viruses causing Covid-19, Flu A, Flu B, and respiratory syncytial virus (RSV) infections from a single patient sample. The new plus version of the test provides a third gene target for…
Researchers have found a possible explanation for why some patients recover much more poorly from brain injury if they later become infected.
Study suggests need for better ventilation and tight-fitting masks, in addition to widespread vaccination to help stop spread of the virus.
Researchers have found a way to defeat the multi-resistant bacterium Mycobacterium abscessus, a relative of the causes of tuberculosis and leprosy.
To better prepare and protect the world from global disease threats, H.E. German Federal Chancellor Dr Angela Merkel and Dr Tedros Adhanom Ghebreyesus, World Health Organization (WHO) Director-General, have inaugurated the new WHO Hub for Pandemic and Epidemic Intelligence, based in Berlin.
Viruses do not always kill the cells they infect. Researchers at the University of Basel have discovered in experiments with mice that cells have the power to self-heal and eliminate viruses. However, these cells undergo long-term changes. The findings may provide a hint as to why cured hepatitis C patients are more susceptible to liver cancer for years after.
To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell…
When viruses infect cells, changes in the cell nucleus occur, and these can be observed through fluorescence microscopy. Using fluoresence images from live cells, researchers at the University of Zurich have trained an artificial neural network to reliably recognize cells that are infected by adenoviruses or herpes viruses. The procedure also identifies severe acute infections at an early stage.
Epstein-Barr virus (EBV) reactivation resulting from the inflammatory response to coronavirus infection may be the cause of previously unexplained long Covid symptoms—such as fatigue, brain fog, and rashes—that occur in approximately 30% of patients after recovery from initial Covid-19 infection. The first evidence linking EBV reactivation to long Covid, as well as an analysis of long Covid…
A new project led by University of California San Diego Biological Sciences graduate student Joshua Borin has provided evidence that phages that undergo special evolutionary training increase their capacity to subdue bacteria.
Months after recovering from mild cases of COVID-19, people still have immune cells in their body pumping out antibodies against the virus that causes COVID-19, according to a study from researchers at Washington University School of Medicine in St. Louis. Such cells could persist for a lifetime, churning out antibodies all the while.
Understanding every step in the life cycle of a virus is crucial for identifying potential targets for treatment. Now, scientists at the Institute of Science and Technology (IST) Austria were able to show how a virus from the retrovirus family – the same family as HIV – protects its genetic information and becomes infectious. Furthermore, they show an unexpected flexibility of the virus. This…
