Implication

Highlights actomyosin-driven hysteresis in contracted vessels; leaves open translation to human vascular physiology.

Structured PICO

Population

Portal veins (in vitro model)

Intervention

Imposed stretch and shortening at rates varying from 0.2 to 47% of initial muscle length/s

Comparator

Relaxed state (Ca-free medium) vs. contractures produced by K+ or hyperosmolar solution

Outcome

Stress-strain relations and force-velocity characteristicssurrogate

The viscous properties of contracted blood vessels, as revealed in stress-strain hysteresis, are largely determined by the force-velocity characteristics of the smooth muscle actomyosin system.
