Optical flow-based vascular respiratory motion compensation [PDF]
arXiv, 2023 This paper develops a new vascular respiratory motion compensation algorithm, Motion-Related Compensation (MRC), to conduct vascular respiratory motion compensation by extrapolating the correlation between invisible vascular and visible non-vascular. Robot-assisted vascular intervention can significantly reduce the radiation exposure of surgeons.

From arteries to boreholes: Steady-state response of a poroelastic cylinder to fluid injection [PDF]
Proceedings of the Royal Society A 473, 20160753 (2017), 2016 The radially outward flow of fluid into a porous medium occurs in many practical problems, from transport across vascular walls to the pressurisation of boreholes. As the driving pressure becomes non-negligible relative to the stiffness of the solid structure, the poromechanical coupling between the fluid and the solid has an increasingly strong impact

The Clinical Significance and Application of Vascular Stiffness Measurements
American Journal of Hypertension, 2018 Increasing evidence points out at vascular stiffness (and in particular aortic stiffness measured by pulse wave velocity) as a reliable biomarker of vascular aging, able to integrate in a single measure the overall burden of cardiovascular (CV) risk ...

From arteries to boreholes: Transient response of a poroelastic cylinder to fluid injection [PDF]
Proceedings of the Royal Society A 474, 20180284 (2018), 2017 The radially outward flow of fluid through a porous medium occurs in many practical problems, from transport across vascular walls to the pressurisation of boreholes in the subsurface. When the driving pressure is non-negligible relative to the stiffness of the solid structure, the poromechanical coupling between the fluid and the solid can control ...

American Journal of Physiology. Heart and Circulatory Physiology, 2018 Increased vascular stiffness correlates with a higher risk of cardiovascular complications in aging adults. Elastin (ELN) insufficiency, as observed in patients with Williams-Beuren syndrome or with familial supravalvular aortic stenosis, also increases ...

ARTERIAL STIFFNESS AS A RISK FACTOR FOR CEREBRAL VASCULAR LESIONS
Artery Research, 2018 Increased arterial stiffness, a biomarker of vascular aging, is a recognized subclinical organ damage, and may thus serve as predictor of cardiovascular disease.

Section properties of palm petioles, Part 1: The influence of section shape on the flexural and torsional properties of selected palm petioles [PDF]
, 2008 Shape factors have been used to calculate the shape efficiency of palm leaf petiole sections in order to understand how palms compensate for the torsional and bending forces put upon them by their environment.

Deletion of the microRNA-degrading nuclease, translin/trax, prevents pathogenic vascular stiffness.
American Journal of Physiology. Heart and Circulatory Physiology, 2019 Vascular stiffness plays a key role in the pathogenesis of hypertension. Recent studies indicatethat the age associated reduction in miR-181b levels in vascular smooth muscle cells (VSMCs)contributes to increased vascular stiffness.
