The discovery of two novel biomarkers, called FKBPL and CD44, has the potential to change the way preeclampsia is managed according to research published in the Journal of Clinical Endocrinology and Metabolism. Preeclampsia can cause high blood pressure and organ failure in mothers and lead to preterm births and even stillbirth.
Major weaknesses exist in the evidence base for COVID-19 antibody tests, finds a review of the latest research published by The BMJ. The evidence is particularly weak for point-of-care tests (performed directly with a patient, outside of a laboratory) and does not support their continued use, say the researchers. Serological tests to detect antibodies against COVID-19 could improve diagnosis and…
An overactive defense response may lead to increased blood clotting, disease severity, and death from COVID-19. A phenomenon called NETosi is part of an immune response that becomes increasingly hyperactive in people on ventilators and people who die from the disease.
Scientists have found that organoids (tiny tissue cultures made from human cells that simulate whole organs) known as “mini-brains” can be infected by the SARS-CoV-2 virus that causes COVID-19.
New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the "International Journal of Molecular Sciences".
East Germany has many more hospitalisations for heart failure compared to West Germany despite a nationwide healthcare system, according to research presented today on HFA Discoveries, a scientific platform of the European Society of Cardiology (ESC). Heart failure is the most common reason for hospital admissions and is responsible for a large part of the total health expenditure on…
A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team's latest in-vitro results, published in Biomaterials Science, suggest that the…
Infections can trigger a particularly strong immune reaction of the body (termed sepsis). In such a sepsis the immune system reacts so strongly that not only the pathogens but also tissues and organs are damaged. In a study with mice, researchers from the Technische Universität Braunschweig were able to show that sepsis can have long-term effects on the brain and learning behaviour even after…
Infection with the novel coronavirus SARS-CoV-2 follows a highly variable course: some of those infected do not even notice it, while others become so seriously ill that their lives are placed at risk. Scientists from the Berlin Institute of Health (BIH) and Charité – Universitätsmedizin Berlin and their colleagues from Leipzig and Heidelberg have now discovered that the immune system has a…
When infected by the new coronavirus, women may mount a more potent adaptive immune response than do men, a new study suggests. By comparison, the male immune response appears to progress less effectively, fostering inflammation that’s harmful to the body. This study is the first to delve into sex differences in how the immune system defends itself against the virus SARS-CoV-2. It could help…
Imagine a dressing that releases antibiotics on demand and absorbs excessive wound exudate at the same time. Researchers at Eindhoven University of Technology (TU/e) hope to achieve just that, by developing a smart coating that actively releases and absorbs multiple fluids, triggered by a radio signal. This material is not only beneficial for the healthcare industry, it is also very promising in…
Scientists from the German Cancer Research Center (DKFZ) and the Universities of Cambridge and Edinburgh have been studying the evolution of tumors following chemical damage. They discovered that the DNA lesions caused by the chemical are not eliminated immediately, but are passed on unrepaired over several rounds of cell division. This "lesion segregation" can drive unexpectedly…
It’s currently difficult to screen for certain liver diseases and to monitor these conditions once they’re discovered. A team led by investigators at Massachusetts General Hospital (MGH) and the Massachusetts Institute of Technology (MIT) recently developed a non-invasive imaging method that has promising clinical potential to accomplish both goals. The technique is described in a study…
A new joint report from the American Diabetes Association (ADA) and the European Association for the Study of Diabetes (EASD) presents the largest venture ever on precision medicine in diabetes. The report includes a detailed overview and roadmap for how this new approach to diabetes medicine can be evaluated and implemented into clinical practice.
Nanoparticles cloaked in human lung cell membranes and human immune cell membranes can attract and neutralize the SARS-CoV-2 virus in cell culture, causing the virus to lose its ability to hijack host cells and reproduce.
Researchers in the UK have shown that a widely available drug reduces death in hospitalised patients with severe respiratory complications of COVID-19.
A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it. Together with colleagues from Australia and Denmark, researchers from Radboud university medical center the universities of Nijmegen and Bonn have now presented a possible answer to this question.
Benchtop tools for studying the respiratory system misrepresent the interdependence between the diaphragm, abdomen and lungs. Meanwhile, computational models often hide the mechanisms in a black box computation, without a clear picture of what transpires in the process. This means students form a poor understanding of respiratory mechanisms and makes it hard to train clinicians for real scenarios…
Researchers from Freie Universität Berlin at the Institute for Animal and Environmental Hygiene and the Institut für Textiltechnik (ITA) of RWTH Aachen University are collaborating on the topic of alternative personal protection equipment. The testing was conducted in the context of the EIT Health Project ViruShield, supported by the European Union, with the objective to discover alternative…
Population-wide use of facemasks keeps the coronavirus ‘reproduction number’ under 1.0, and prevents further waves of the virus when combined with lockdowns, a modelling study led by the University of Cambridge suggests. The research suggests that lockdowns alone will not stop the resurgence of SARS-CoV-2, and that even homemade masks with limited effectiveness can dramatically reduce…
An algorithm that analyses MRI images and automatically detects small changes in knee joints over time could be used in the development of new treatments for arthritis. A team of engineers, radiologists and physicians, led by the University of Cambridge, developed the algorithm, which builds a three-dimensional model of an individual’s knee joint in order to map where arthritis is affecting the…
Neurons that are responsible for new experiences interfere with the signals of neurons that contain memories and thereby disturb the recall of memories – at least in mice. The research group of Martin Fuhrmann of the German Center for Neurodegenerative Diseases (DZNE) reports this phenomenon in the scientific journal “Nature Neuroscience“. The results of this study potentially shed new…
Resistance of cancer cells against therapeutic agents is a major cause of treatment failure, especially in recurrent diseases. An international team around the biochemists Robert Ahrends from the University of Vienna and Jan Medenbach from the University of Regensburg identified a novel mechanism of chemoresistance which has now been published in "Nature Communications". It is driven by…
Our body is able to treat many injuries and wounds all by itself. Self-healing powers repair skin abrasions and enable bones to grow back together. However, doctors often have to lend a helping hand to repair bones after a fracture or due to a defect. Increasingly, bone replacement materials are being used, which partially or completely restore the form and function of the bone at the site of the…
Resistance to antibiotics has become a serious public health problem. Hospital infections, prostheses or surgical implants that become infected and do not respond to treatment are a real challenge to the research community, which has been seeking alternatives for effectively eliminating these bacteria for years. In 2012 the researchers from the Department of Chemical Engineering of the…
