Viscoelastic properties of rat (Wistar Kyota) large (6 aorta), medium (12 carotid) and small (8 femoral) in vitro artery segments, were contrasted over a wide range of static and dynamic pressures. Relationship of change in static pressure (delta dyn

This study examined the relationship between rat (mature Sprague-Dawley males) thoracic aortic wall and intraluminal pressure responses to a dynamic pressure input. High speed video image (Do) of outer wall area and intravascular pressure (Po) respon

To assist in the identification of physical/physiological parameters obtained from in vivo rat aortic artery dynamic pressure data, the natural (mobility) mechanical circuit model was constructed. The direct electrical analog of the model thus obtain

Harmonic analysis of the pressure and wall responses of a blood vessel exposed to a dynamic pressure input signal required the development of a software application which could properly synchronize the data gathered by two separate microcomputers. In

We hypothesized that results from rabbit carotid sinus wall and baroreceptors could be simulated using exponential feedback in a viscoelastic model. Wall and baroreceptor were each modeled by second order differential equations. Coefficients for visc

Blood pressure regulation involves feedback signals from baroreceptors detecting wall strain of arterial sinuses. A research goal is identification of wall viscoelastic properties and associations between elements and baroreceptors. This report prese

In pentobarbital-anesthetized rabbits with aortic nerves cut, reflex heart rate and mean arterial pressure (MAP) changes were quantified in response to maximal central stimulation of the left aortic nerve (LANS) before and during steady-state changes

Factors that modify carotid vascular baroreflexes were studied in anesthetized rabbits after section of the cervical aortic nerves. We recorded steady-state reflex responses of heart rate (HR) and mean arterial pressure (MAP) to changes in isolated n
