13/01/2021A rapid, evidence-based review summarizes the effectiveness of cloth masks in protecting health care clinicians from respiratory viral infections, such as COVID-19. Nine studies were included in the review, and all but one were conducted prior to the COVID-19 pandemic.
13/01/2021Aneurysm operations in the brain rank among the most delicate procedures in neurosurgery. The highest demands are placed on surgeons when choosing the type of intervention, planning the route and carrying out extremely delicate procedures on the blood vessel.
12/01/2021Texas A&M researchers have designed a device that stimulates the endings of the vagus nerve, which is responsible for the regulation of food intake.
12/01/2021Engineering researchers have developed a new technique for eliminating particularly tough blood clots, using engineered nanodroplets and an ultrasound "drill" to break up the clots from the inside out. The technique has not yet gone through clinical testing. In vitro testing has shown promising results.
11/01/2021The clock drawing test has been used for several decades as a simple and effective means of diagnosing disruptions to spatial orientation and dementias. Scientists at the Pattern Recognition Lab at the Department of Computer Science at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) fed AI neural networks with data from 2500 tests to teach them how to assess these results independently.
11/01/2021Prof. Volker Busskamp from the University of Bonn has received a "Proof of Concept Grant" worth 150,000 euros from the European Research Council (ERC). He and his team are working at the Eye Clinic of the University Hospital Bonn on a technology to rapidly program human stem cells to photoreceptor for retinal research and treating blindness in the future.
08/01/2021Stomach cancer, or gastric cancer, is a common gastrointestinal malignancy. Peritoneal metastasis occurs in a majority of patients with advanced stomach cancer and is considered as an aggressive disease with poor outcomes.
08/01/2021Medical professionals all want to be able to quickly and correctly diagnose diseases. Their future ability to do so will depend on identifying what biochemicals are present in tissue sections, where the biomolecules are, and at what concentrations. For this purpose, mass spectrometry imaging – which can identify multiple biochemicals in a single experiment – will be useful.
07/01/2021An accident, such as falling on a ski slope, usually requires an X-ray examination of the injured limb and a trip to the nearest hospital or emergency clinic. In the near future, imaging services can be brought closer to the patient. Researchers in Oulu are currently developing a compact X-ray imaging device that even the patient could use if necessary.
07/01/2021A new advanced computing technique using routine medical scans to enable doctors to take fewer, more accurate tumour biopsies, has been developed by cancer researchers at the University of Cambridge.
