Pressure-Induced Intracellular Signaling in Isolated Arteries
… to mechanical stimuli such as stretch, and pressure.</p> <p>This study attempts to add to the current knowledge of mechanotransduction by utilizing the isolated artery preparation. This preparation allows for the study of vascular smooth muscle signal transduction in response to …

Regulation of the myogenic response and stretch-induced calcium signaling in the vascular wall: Novel insights into the role of microRNAs and protein tyrosine kinase 2
Intraluminal pressure has a significant impact on vascular adaptability, phenotype and regulation of blood flow and pressure. On one hand, increased pressure/stretch for a prolonged time can cause structural changes in vessel wall; on the other hand, lack of pressure/stretch can promote a phenotype …

Determining ideal staple size for small intestinal surgery in cats
… cat jejunum, were evaluated via intestinal burst pressure testing for maximum intraluminal pressure prior to leaking, and via infusion of an intravascular dye at normal arterial pressures to determine percentage of vascular patency past the staple lines. Vascular patency was compared not only from …

Neuronal plasticity in the enteric nervous system motor pathways
… Each segment was cannulated and the peristaltic pressure threshold was determined by step-wise increases of the intraluminal pressure from the oral end while pressure recordings were made from the aboral end. Parameters of the peristaltic motor pattern were compared in electrically stimulated and …

Development of hydraulic propulsion for colonoscopic devices
… colonoscope is described, which utilises intraluminal water pressure to propel it through the colon. This approach was assessed in experiments using ex vivo porcine colons arranged to model human anatomy. The results suggest that a hydraulic colonoscope can successfully be propelled though …

Hemodynamics Due to Calf Muscle Activity-Biophysical Modeling and Experiments Using Frequency Domain Near Infrared Spectroscopy in Healthy Humans
… intramuscular and deep veins. This increases the intraluminal pressure that drives this venous flow while retrograde flow is prevented through the action of a system of muscular venous pumps and bicuspid valves. Here, aging and many cardiovascular diseases are related to abnormal cardiac output …
