Major sugar substitute found to impair brain blood vessel cell function, posing potential stroke risk
Erythritol may impair cellular functions essential to maintaining brain blood vessel health, according to researchers at the University of Colorado Boulder. Findings suggest that erythritol increases oxidative stress, disrupts ...
Better than stitches: Researchers develop biocompatible patch for soft organ injuries
University of California, Los Angeles and University of California, San Diego researchers developed an injectable sealant for rapid hemostasis and tissue adhesion in soft, elastic organs.
Seeing blood clots before they strike: Imaging technique shows how platelets behave in real time
Researchers from the University of Tokyo have found a way to observe clotting activity in blood as it happens—without needing invasive procedures. Using a new type of microscope and artificial intelligence (AI), their study ...
