Mass General Brigham researchers suggest a new method for interpreting pulse-rate data could help identify older adults who may experience a more rapid decline in cognitive function. The team measured “heart rate complexity” with the Itamar WatchPAT 300, a fingertip pulse oximetry device worn overnight. Rather than examining traditional heart rate variability, the researchers tracked…
Researchers engineer functional blood vessels in lab-grown liver tissue
Scientists from TU Wien in Austria and Keio University in Japan have developed a scalable method to create artificial blood vessels in microfluidic chips. The researchers say that the advance could improve how researchers model organ behavior and test new drugs by enabling perfusable vascular networks that mimic real human tissue. Organs-on-a-chip have gained traction…
