A new mechanism has been discovered by which cells infected with the foodborne pathogen Listeria monocytogenes are able to escape the immune response, and which at the same time confers a higher probability that infected cells will adhere to and infect cerebral vessels and cross the blood-brain barrier.
A smart contacts lens that detects diabetes and treats diabetic retinopathy could provide patients with a more comfortable alternative to insulin shots and monitoring blood glucose levels. The product was developed by a research team at the Pohang University of Science & Technology (POSTECH) that includes Sei Kwang Hahn, the CEO of Seoul, South Korea-based Phi Biomed Co. Ltd.
By using roughly 400 data points, from molecular to physical fitness, researchers have gained new insights into how organs such as the heart vs. the skin, and systems such as the immune and metabolic systems, age at different rates within individuals.
A research team from the Technical University of Munich (TUM) in Germany has for the first time managed to integrate the dark-field X-ray technique into a CT scanner suitable for clinical application. They have just published an article describing how they integrated this technology, in the journal Proceedings of the National Academy of Sciences.
By combining an activator of the pro-apoptotic protein Bax with an inhibitor of the anti-apoptotic protein BCL-XL, researchers at Albert Einstein College of Medicine have been able to overcome resistance to apoptosis in both a wide range of cell lines and animal studies. The team reported its findings in the March 7, 2022, issue of Nature Communications.
Russia and Belarus are being frozen out of international science, with universities and research institutions across Europe suspending joint research projects and calling a halt to the formation of any new collaborations, following the invasion of Ukraine. Initial sanctions announced by European governments called for the severing of direct institution-to-institution links only, with many universities counseling individual researchers to maintain personal relations with Russian peers.
The discovery of increased levels of dopamine in the basolateral amygdala of the brain at the transition from non-rapid eye movement (NREM) to REM sleep in mice suggests a druggable sleep disorder target, according to a Japanese study.
A team of researchers at Tokyo Metropolitan University have discovered that osmolytes such as mannitol, which are used to treat increased intraocular or intracranial pressure, can cause kidney damage by inducing hyperosmotic stress that leads to epithelial-mesenchymal transition (EMT) of the tubular epithelial cells.
