New research hypothesizes narrowing blood vessels in the brain plays a role in the cognitive decline associated with Alzheimer's disease

Following yet another failed clinical trial testing a novel drug designed to break up the aggregations of toxic proteins thought to be the cause of Alzheimer’s disease, a new study suggests we look to a different part of the brain in the hopes of finding a treatment. Led by researchers from the University of Manchester the new study found disruptions to blood vessels in the brain may be contributing to the neurodegeneration seen in Alzheimer’s.

Smart artery stent wirelessly transmits blood flow data

Posted on by

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.Continue… Continue reading Smart artery stent wirelessly transmits blood flow data→

Exercise found to promote new blood vessel growth in diabetic mice

Posted on by

One of the harmful effects of diabetes is the way it impacts on the blood vessels, not only narrowing them to drive up the risk of stroke and heart attacks but preventing the formation of entirely new ones. Researchers have produced what they say is th… Continue reading Exercise found to promote new blood vessel growth in diabetic mice→

Risk of serious blood clot events spike in the months after COVID-19

Posted on by

New observational research out of Sweden has tracked more than one million COVID-19 cases for months after their acute illness in order to determine how the disease influences subsequent risk of blood clots. The findings indicate COVID-19 significantly… Continue reading Risk of serious blood clot events spike in the months after COVID-19→

Taste receptors found in lung blood vessels could help ICU patients

Posted on by

Scientists have discovered bitter taste receptors in an unexpected part of the body – the walls of blood vessels in the lungs. The find could be an important new drug target to treat acute respiratory distress syndrome (ARDS), a dangerous complication … Continue reading Taste receptors found in lung blood vessels could help ICU patients→

Insect-inspired catheter steers through brain’s intricate pathways

Posted on by

With its extremely narrow and delicate blood vessels, the brain poses a unique challenge for surgeons trying to get at its various nooks and crannies, and there are limitations to what current catheters can achieve. Scientists have developed a first-of… Continue reading Insect-inspired catheter steers through brain’s intricate pathways→

Smart stent coatings release drugs for better artery healing

Posted on by

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.Continue ReadingCategor… Continue reading Smart stent coatings release drugs for better artery healing→

Artificial aorta takes pressure off the heart to reduce transplants

Posted on by

When the heart is injured it can’t repair itself, meaning that heart failure often requires a transplant of the whole organ. But now, scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the he… Continue reading Artificial aorta takes pressure off the heart to reduce transplants→

Ultrasound drill uses nanodroplets to bust up tough blood clots

Posted on by

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.Con… Continue reading Ultrasound drill uses nanodroplets to bust up tough blood clots→

Electronic blood vessels can be tuned to deliver DNA and heal wounds

Posted on by

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. These electronic blood vessels can be used … Continue reading Electronic blood vessels can be tuned to deliver DNA and heal wounds→
