        "summary": "Australian and Chinese researchers have created an 'artery-on-a-chip' that mimics patient-specific blood vessel structures and flow dynamics to better predict stroke risk. The study suggests that vessel shape and local blood flow disturbances are more critical factors than narrowing alone. The team is now recruiting stroke patients for clinical trials, aiming to enable personalised treatment based on individual anatomy.",

The team is currently recruiting\nstroke patients to take part in clinical trials.<\/p>",
