Following yet another failed clinical trial testing a drug designed to break up the aggregations of proteins thought to be the cause of Alzheimer’s, a new study suggests we look to a different part of the brain in the hopes of finding a treatment.
-
Stents can make a life-saving difference for people with vascular problems, as they open up narrowing blood vessels. An experimental new one goes a step further, by actually transmitting blood flow data to an external computer or mobile device.
-
Researchers have produced what they say is the first evidence that exercise can promote growth of new blood vessels in the face of diabetes, and point to drugs already under development that could mimic this process for sufferers of the disease.
-
New research has tracked more than one million COVID-19 cases after their illness and found a person’s risk of blood clotting events such as deep vein thrombosis and pulmonary embolism significantly increase in the months after infection.
-
Scientists have discovered bitter taste receptors in the walls of blood vessels in the lungs. The unexpected find could be an important new drug target to treat acute respiratory distress syndrome (ARDS), a dangerous complication of many diseases.
-
Scientists have developed a first-of-a-kind "steerable" catheter that takes inspiration from insects to safely navigate the brain's arteries and blood vessels, which could open up new possibilities for treating hard-to-reach aneurysms.
-
Scientists have developed a new type of smart stent that can help prevent some of the complications these implants bring. The stent is coated in a substance that minimizes the inflammatory response, while promoting tissue repair.
-
Heart failure often requires a transplant of the whole organ. Now scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the heart to reduce or even eliminate the need for a transplant.
-
Blood clots can be dangerous, and blood thinning drugs aren’t always enough to clear them out. Now, researchers at North Carolina State University have demonstrated an ultrasonic “drill” that can break clots apart with the help of tiny nanodroplets.
-
Scientists in China and Switzerland have teamed up to produce an implantable medical device that mimics the primary function of blood vessels, but goes a number of steps further than its natural counterparts.
-
Heart attack patients often need replacements for damaged arteries. In a new proof-of-concept study, scientists knitted a prototype graft out of hybrid synthetic and biological yarn, helping the patients own cells grow and repair the artery.
-
First responders don’t have the same tools that emergency rooms do. Now, Harvard scientists have developed a new blood-clotting material that’s portable and easy to store, potentially helping injured patients survive long enough to reach a hospital.
