A collaboration between the University of Toronto's Faculty of Dentistry and the National Jewish Health in Denver -- the top-ranked respiratory research hospital in the US -- has yielded a new drug discovery that could be useful to combat inflammation of all varieties and shows promise in fighting acute respiratory illnesses such as COVID-19.
Some people are better protected than others against urinary tract infections. This may be because their bodies produce more of a protein called uromodulin. An interdisciplinary research team has now found out exactly how this helper protein brings relief when nature calls and how this knowledge might benefit the treatment and prevention of these painful inflammations.
Researchers have solved the mystery of why a species of bacteria that causes food poisoning can swim faster in stickier liquids, such as within guts.
Using X-ray-based technology developed at Brown University, researchers uncover shared subsurface movement patterns between birds and dinosaurs, adding a new dimension of fossil track diversity.
New details are known about an important cell structure: For the first time, two Würzburg research groups have been able to map the synaptonemal complex three-dimensionally with a resolution of 20 to 30 nanometres.
Scientists used a combination of advanced microscopy and chemical detection techniques to uncover the structural makeup of human tooth enamel at unprecedented atomic resolution, revealing lattice patterns and unexpected irregularities. The findings could lead to a better understanding of how tooth decay develops and might be prevented.
The St. Pölten UAS and the Austrian general accident insurance institution AUVA have made one of the biggest data records for automated gait analysis worldwide openly accessible. Researchers are free to use the data in order to improve automated gait analysis with the help of methods such as machine learning. The dataset and the accompanying description were recently published in the magazine "Scientific Data" of the renowned publishing house Nature.
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".
It is well established the COVID-19 virus is transmitted via respiratory droplets. Consequently, much research targets better understanding droplet motion and evaporation. In Physics of Fluids, researchers developed a mathematical model for the early phases of a COVID-19-like pandemic using the aerodynamics and evaporation characteristics of respiratory droplets. The researchers modeled the pandemic dynamics with a reaction mechanism and then compared the droplet cloud ejected by an infected person versus one by a healthy person.
Spider silk is useful for a variety of biomedical applications: It exhibits mechanical properties superior to synthetic fibers for tissue engineering, and it is not toxic or harmful to living cells. One unexpected application for spider silk is its use in the creation of biocompatible lenses for biological imaging applications. Researchers describe the feasibility of creating lenses capitalizing on the properties of natural spider silk material in the Journal of Applied Physics.
