Lymphatic Functional Adaptations to Prolonged Changes in Mechanical Stimuli
… contend with the wide ranges of lymph flow and pressure. Sharing with blood vessels an acute sensitivity to mechanical stresses, lymphangions could be expected to be similarly sensitive to prolonged changes in transmural pressure and flow. The purpose of this research was to quantify the …

Reconstructing the blood pressure waveform using a wearable photoplethysmograph sensor and hydrostatic pressure variations measured by accelerometers
… is the assessment of the arterial blood pressure waveform. The variations in shape of the waveform indicate the presence of disease. In this work, a method is developed for the reconstruction of arterial blood pressure waveform using the signals obtained from a noninvasive wearable …

Coronary flow mechanics: an anatomically based mathematical model of coronary blood flow coupled to cardiac contraction
… variation of resistance and compliance with pressure by fitting results from published anatomical data. The venous network is assumed to parallel the generated arterial model. The calculated blood flow through the network model demonstrates physiological pressure drops, flow rates and a …

Endothelial cell impact on smooth muscle cell properties: role of hemodynamic forces
… against the endothelium, and cyclic strain, transmural pressure due to the pulsatile nature of blood flow. Both forces can profoundly modulate vascular endothelial metabolism and function and, within normal physiological ranges, typically impart an atheroprotective effect which disfavours …

A Fluid Structure Interaction Model Of Intracoronary Atherosclerotic Plaque Rupture
… of thin-walled cylinder subjected to radial pressure. Several FSI indices are first defined by normalizing the predicted hemodynamic endothelial shear stress by the structural stresses, specifically, by the maximum principal stress (giving the ratio ), and the Von Mises stress (giving the …

Malarial retinopathy and neurovascular injury in paediatric cerebral malaria
… damage to tight junctions and by increasing transmural pressure secondary to venous congestion. Several types of retinal leakage are seen and some of these may represent re-perfusion rather than acute injury. Future work to investigate temporal changes in retinal signs may find clearer …
