blood vessel

In a significant development for brain health, scientists have found that hemorrhages can occur due to a faulty interaction between aged red blood cells and narrow capillaries. Injured or damaged blood vessels were thought to be the sole culprit.

While statin drugs are good at controlling plaques in blood vessels, they can't eliminate them once they are established. But researchers may have just found a way to blast the circulatory system clean using a common nutrient found in many foods.

A new study has found that short blood pressure fluctuations – across a day or several days – increase the risk of dementia in older adults. The findings suggest that blood pressure variability could be an early marker of cognitive impairment.

The blood-brain barrier performs a vital function in keeping out toxins and pathogens, but it can become “leaky.” Now Stanford scientists have identified therapeutic molecules that could help patch it up, to potentially prevent neurological diseases.

Researchers have combined two different 3D-printing techniques to produce artificial blood-vessel prototypes. The process created tubes that can be covered in live cells while retaining the strength they need to function under pressure.

It goes without saying that if someone has a blood clot in their brain, that clot should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existing methods.

Scientists are claiming an advance in regenerative medicine through the development of a novel material that mimics the structure of living blood vessels, which sees it grow with the body after transplantation.

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.
