13/08/2020Optical-resolution photoacoustic microscopy is a powerful imaging tool with a superb ability to image rich optical absorption contrast in biological tissue. Most OR-PAM systems today rely on mechanical scanning to form an image, which restrains their imaging speed. To overcome the restraint, multifocal OR-PA computed tomography had been developed.
12/08/2020Enzymes used by bacteria to break down mucus in the gut could provide a useful biomarker for intestinal diseases, according to new research published in Nature Communications. Researchers at the University of Birmingham and Newcastle University have successfully identified and characterised one of the key enzymes involved in this process.
12/08/2020In order to combat bacterial wound infections, Empa researchers have developed cellulose membranes equipped with antimicrobial peptides. Initial results show: The skin-friendly membranes made of plant-based materials kill bacteria very efficiently.
11/08/2020Researchers from Columbia Engineering and the University of Pittsburgh have developed a sensitive and specific early warning system for predicting NEC in premature infants before the disease occurs. The prototype predicts NEC accurately and early, using stool microbiome features combined with clinical and demographic information.
11/08/2020Although macrophages are classified as immune cells functioning in the activation and resolution of tissue inflammation, it is now clear that they are critically involved in a variety of disease processes, such as chronic inflammatory diseases, tumor growth and metastasis and tissue fibrosis.
10/08/2020Engineers at the UCLA Samueli School of Engineering and their colleagues at Stanford School of Medicine have demonstrated that drug levels inside the body can be tracked in real time using a custom smartwatch that analyzes the chemicals found in sweat. This wearable technology could be incorporated into a more personalized approach to medicine.
10/08/2020An international consortium succeeded in tracking the genesis and spread of new reassortants of avian influenza viruses by the use of mathematical analyses. This large-scale international study has now been published in the scientific journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
07/08/2020As COVID-19 cases in the United States continue to surge, there is an ongoing search for quick and reliable testing. Though there are conflicting opinions on using chest computerized tomography (CT) scans as a method of screening in the United States, the technology has been successfully used to identify the disease in other parts of the world.
07/08/2020A new blood test demonstrated remarkable promise in discriminating between persons with and without Alzheimer's disease and in persons at known genetic risk may be able to detect the disease as early as 20 years before the onset of cognitive impairment, according to a large international study published in Journal of the American Medical Association (JAMA).
06/08/2020One of the most dangerous effects of coronavirus is the inability to breathe on your own - requiring the help of a ventilator to push air through your lungs. Consequently, the severity of the coronavirus pandemic has resulted in ventilator shortages, causing some hospitals to assign multiple patients to one machine, limiting effective treatment.
