blood vessel

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.

Studies have seen physical activity slow age-related vision loss, but it hasn’t been clear how causal that relationship has been. New research is now offering the first evidence to show how exercise can directly slow, or prevent, macular degeneration.

New research from the University of Colorado Boulder has offered some of the clearest evidence to date showing how the gut microbiome produces a metabolite that, over time, contributes to age-related declines in cardiovascular health.

A study is offering the first evidence of a causal link between gut bacteria and neurovascular disease. It suggests a microbial metabolite can travel through the bloodstream, reach blood vessels in the brain and expedite the development of lesions.

When a damaged blood vessel has to be replaced, it's important that the replacement be well-tolerated by the body. And while bioprinted blood vessels are one possibility, French scientists are now working on weaving the things out of collagen yarn.

Fighting cancer can sometimes feel like a game of Whack-A-Mole – even after a primary tumor is removed the disease can crop up again in other organs. Now, researchers have developed a drug that can prevent cancer from spreading.

New research from the Perelman School of Medicine at the University of Pennsylvania has shown nicotine-free e-cigarette vapor can have an immediate harmful effect on the body's vascular function.

3D printing organs is going through some teething issues. Now researchers have found a surprisingly simple answer to the complex problem of printing detailed vascular networks, and shown it off with a dramatic model of a breathing lung that passes oxygen into surrounding blood vessels.

Building on recent research finding associations between a breakdown in the blood-brain barrier and the onset of cognitive impairment, a new study has homed in on a specific blood-clotting protein that can trigger synaptic damage after leaking into the brain.

​New research has described a novel peptide found in the venom of vampire bats could pave the way for an entirely new class of blood-pressure “wonder drugs”. However, the study is being stifled by drug cartels taking over the research site in Mexico.​
