Scientists at the University of Basel discovered a fundamental new mechanism explaining the inadequate immune defense against chronic viral infection. These results may open up new avenues for vaccine development.
A new study by Johns Hopkins researchers suggests that a specialized area of the mosquito brain mixes tastes with smells to create unique and preferred flavors. The findings advance the possibility, they say, of identifying a substance that makes “human flavor” repulsive to the malaria-bearing species of the mosquitoes, so instead of feasting on us, they keep the disease to themselves,…
Malaria remains one of the world’s leading causes of mortality in developing countries. Last year alone, it killed more than 400,000 people, mostly young children. An international consortium of researchers unveiled the mechanics and findings of a unique “open science” project for malaria drug discovery that has been five years in the making.
A mobile fridge invented by a British student could help save countless lives across the globe. The “Isobar” has been designed to keep vaccines at the required temperatures when being transported around developing countries.
Researchers have found that Zika virus can live in eyes and have identified genetic material from the virus in tears, according to a study from Washington University School of Medicine in St. Louis. The research, in mice, helps explain why some Zika patients develop eye disease, including a condition known as uveitis that can lead to permanent vision loss.
Curetis N.V. announced the successful completion of the CE Performance Evaluation study of the next generation of its Unyvero ITI Implant and Tissue Infection Application Cartridge (Unyvero ITI).
Researchers have discovered that secondary infection with the Methicillin-resistant Staphylococcus aureus (MRSA) bacterium (or “superbug”) often kills influenza patients because the flu virus alters the antibacterial response of white blood cells, causing them to damage the patients’ lungs instead of destroying the bacterium. The study suggests that inhibiting this response may help treat…
The first known household survey examining the collateral harm to pregnancy services in areas affected by the West African Ebola epidemic suggests a significant slide backwards in child and maternal health. The study, conducted in Liberia, points to the deep disruptions caused by the Ebola epidemic — even in parts of the country with relatively limited transmission.
Osnabrueck cognitive scientists and their students are developing new and intelligent expert systems, which help to effectively utilize the flood of daily information in everyday life. To enable working with large amounts of data, the Institute of Cognitive Science at Osnabrück University has engaged in a cooperation with the global corporation IBM, and will be able to access the IBM computer…
A study published by The BMJ provides more details of an association between Zika virus infection in the womb and a condition known as arthrogryposis, which causes joint deformities at birth, particularly in the arms and legs.
Research by scientists in the US and UK has estimated that up to 1.65 million childbearing women in Central and South America could become infected by the Zika virus by the end of the first wave of the epidemic. Researchers from the WorldPop Project and Flowminder Foundation at the University of Southampton and colleagues from the University of Notre Dame and University of Oxford have also found…
Scientists at Washington University School of Medicine in St. Louis have identified antibodies capable of protecting against Zika virus infection, a significant step toward developing a vaccine, better diagnostic tests and possibly new antibody-based therapies. The work, in mice, helps clarify recent research that also identified protective Zika antibodies but lacked important details on how the…
A new, epidemic strain of C. difficile is proving alarmingly deadly, and new research from the University of Virginia School of Medicine not only explains why but also suggests a way to stop it.
The U.S. Food and Drug Administration (FDA) has granted Siemens Healthcare Diagnostics Inc. (Siemens) an Emergency Use Authorization (EUA) for its real-time PCR Zika Virus assay, the VERSANT® Zika RNA 1.0 Assay (kPCR) Kit. With respect to Zika in vitro diagnostic tests, FDA has been authorized to issue EUAs to allow for use of unapproved medical products or unapproved uses of approved medical…
Clinicians around the world have long suspected that bacteraemia due to Staphylococcus aureus has a worse outcome in women compared to men, but direct evidence has been elusive. A study just published confirms that significantly more women than men diagnosed with Staphylococcus aureus bacteraemia (SAB) – a blood infection of the common bacteria – die within 30 days.
Hospital-acquired Clostridium difficile infection (CDI) is on the rise. Symptoms range from non-typical mild diarrhoea that can develop into pseudomembranous colitis up to a toxic megacolon, which often leads to death.
Wound infections after surgery are not uncommon and can be fatal. In Germany, postoperative wound infections are now the most common type of hospital acquired infection (HAI), with a proportion of 24%.
Scientists at the Institute of Molecular Biotechnology (IMBA) and the Max F. Perutz Laboratories (MFPL) in Vienna have discovered a new way to turn the immune system’s weapons against fungal invaders. This knowledge could lead to the development of new and improved anti-fungal treatments.
With a goal of treating worn, arthritic hips without extensive surgery to replace them, scientists have programmed stem cells to grow new cartilage on a 3-D template shaped like the ball of a hip joint. What’s more, using gene therapy, they have activated the new cartilage to release anti-inflammatory molecules to fend off a return of arthritis. The technique was demonstrated in a collaborative…
No one knows for sure how they got there. But the discovery that bacteria that normally live in the gut can be detected in the lungs of critically ill people and animals could mean a lot for intensive care patients.
Most people recoil at the thought of ingesting E. coli. But what if the headline-grabbing bacteria could be used to fight disease? Researchers experimenting with harmless strains of E. coli — yes, the majority of E. coli are safe and important to healthy human digestion — are working toward that goal. They have developed an E. coli-based transport capsule designed to help next-generation…
A receptor, first known for its role in mediating the harmful effects of the environmental pollutant dioxin in our body, is now understood to play other important roles in modulating the innate immune response.
Bacterial infections that don't respond to antibiotics are of rising concern, as is sepsis - the immune system's last-ditch, failed attack on infection that ends up being lethal itself. Reporting online in "Nature", researchers at Boston Children's Hospital describe new potential avenues for controlling both sepsis and the runaway bacterial infections that provoke it.
The study by researchers from the Department of Neurology at the University of Ulsan College of Medicine in Seoul showed that herpes zoster infection not only raised the risk of ischaemic and haemorrhagic stroke but also that of a transient ischaemic attack (TIA), a warning mini-stroke often preceding a full-blown stroke.
Jens Hahn MD is an Internal Medicine and Intensive Care Specialist who works with the international, independent, medical humanitarian organisation Médecins Sans Frontières (MSF in English: Doctors Without Borders). Here he describes his work in Afghanistan and South Sudan, and the use of rapid diagnostic tests in the field.
