Brain imaging In addition to revealing cells, the team used ultrasound and microbubbles as probes circulating in the bloodstream to detect brain capillaries. Heiles notes, "To our knowledge, nonlinear ...

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 ...

Burlington, Vt.— 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 ...

Researchers found that endothelial cells lining the veins in lungs contribute to repair of blood vessels after lung injury. Veins in the lungs, or pulmonary veins, play a critical role not only in ...

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists have now developed a microscopy technique based on ...

Ultrasound is one of the most widely used imaging techniques in medicine, but up until recently it hardly played a role in imaging the tiniest structures of our bodies such as cells. “Clinical ...
