How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer lies not only in biology—but also in physics. Researchers at Åbo Akademi ...
A team of UVM scientists led by Mark Nelson, Ph.D., from the Larner College of Medicine at the University of Vermont, has uncovered a novel mechanism that reshapes our understanding of how blood flow ...
Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...

New noninvasive tools reveal that subtle shifts in brain blood flow and oxygen use may mirror key markers of Alzheimer’s risk ...
Researchers have discovered that a certain type of cell that sits on top of the brain's smallest blood vessels senses when their brain region needs energy. When glucose levels are low, these cells ...
The nuclear stress test can show how blood flows through your heart muscles. This reveals how well the heart pumps blood and areas of your heart muscles that do not get enough blood. Nuclear stress is ...
