ESO guidelines provide recommendations on intravenous thrombolysis for acute ischemic stroke Patients with stroke due to blood clots in brain arteries (ischaemic stroke) can be treated with clot-dissolving drugs called thrombolytics. By dissolving blood clots, thrombolytic drugs improve brain blood supply and lead to better recovery. However, thrombolytic drugs may cause bleeding in the brain which can lead to worse disability or death. The most commonly used thrombolytic drug for ischemic stro...

New isolated lymphatic vessel lumen perfusion system to evaluate nanoparticle dynamics Nanoparticles used in drug delivery systems, bioimaging, and regenerative medicine migrate from tissues to lymphatic vessels after entering the body, so it is necessary to clarify the interaction between nanoparticles and lymphatic vessels. Although technology to observe the flow of nanoparticles through lymphatic vessels in vivo has been developed, there has been no method to evaluate the flow of nanoparticl...

An optimized process to isolate and purify magnetic nanoparticles Magnetic nanoparticles biosynthesized by bacteria might soon play an important role in biomedicine and biotechnology. Researchers of the University of Bayreuth have now developed and optimized a process for the isolation and purification of these particles from bacterial cells. In initial tests, magnetosomes showed good biocompatibility when incubated with human cell lines. The results presented in the journal "Acta Biomaterialia...

Understanding the dynamics of brain blood flow could hold key for treating neurologic conditions While the human brain has over 400 miles of total vasculature, little is known about the tiny capillaries that make up much of this intricate labyrinth of blood vessels critical for delivering oxygenated blood and nutrients to billions of brain cells. According to Dr. Andy Shih, a principal investigator in the Center for Developmental Biology and Regenerative Medicine at Seattle Childrens Research I...

Developing Biochemically Sensitive Membranes with Electrochemistry Thought LeadersLane BakerProfessor of ChemistryIndiana University Bloomington In this interview, News-Medical Life Sciences talks to Lane Baker, Professor of Chemistry at Indiana University Bloomington about the role of electrochemistry in developing biochemically sensitive membranes as well the work ongoing at the Baker lab. Can you define nanoscale electrochemistry? The term ‘nanoscale electrochemistry’ has two meanings: ...

New collaborative project to study the complex roles of lipids in health, disease A University of Minnesota-Mayo Clinic partnership has joined with the Zooniverse citizen scientist platform and the Francis Crick Institute in London to leverage world-leading expertise in microscope imaging with the power of citizen science to study the relationship between structure and function in biology to better understand health and disease. The Minnesota Microscopy Infrastructure Partnership, led by the Ma...

Radiological images reveal how COVID virus can trigger the body to attack itself Muscle soreness and achy joints are common symptoms among COVID-19 patients. But for some people, symptoms are more severe, long-lasting, and even bizarre, including rheumatoid arthritis flares, autoimmune myositis, or "COVID toes." A new Northwestern Medicine study has, for the first time, confirmed and illustrated the causes of these symptoms through radiological imaging. "Weve realized that the COVID virus can t...

Mummified Remains of Ancient Egyptian Pharaoh Reveal a Reign Ended in Violence TIM THOMPSON, THE CONVERSATION 17 FEBRUARY 2021 Theres something about mummies that always fascinates people. We see this from the attention given to mummies in museum exhibitions and in their frequent appearance in books, films and games.   Perhaps its the fact that they are dead yet still very identifiable as people – in some way simultaneously dead and living. Whatever the reason, its always exciting when a ...

New 3D imaging technique helps detect breast cancer, COVID-19, other diseases A research team led by UMass Lowell is pioneering a new 3D imaging technique to better detect breast cancer and other diseases, including COVID-19. The noninvasive medical technology uses specialized contrasting dye that recognizes breast cancer cells, allowing practitioners to better visualize human tissue inside the body. The dye amplifies the X-ray signal in tumors when used together with a state-of-the-art compute...
