Three-dimensional Multiscale Model of Deformable Platelets Adhesion to Vessel Wall in Blood Flow [PDF]
, 2013 When a blood vessel ruptures or gets inflamed, the human body responds by rapidly forming a clot to restrict the loss of blood. Platelets aggregation at the injury site of the blood vessel occurring via platelet-platelet adhesion, tethering and rolling on the injured endothelium is a critical initial step in blood clot formation.

Aortic frequency response determination via bioimpedance plethysmography [PDF]
, 2019 Objective: Arterial stiffness is an important marker to predict cardio vascular events. Common measurement techniques to determine the condition of the aorta are limited to the acquisition of the arterial pulse wave at the extremities. The goal of this work is to enable non-invasive measurements of the aortic pulse wave velocity, instead. An additional

Extraction of Vascular Wall in Carotid Ultrasound via a Novel Boundary-Delineation Network [PDF]
arXiv, 2022 Ultrasound imaging plays an important role in the diagnosis of vascular lesions. Accurate segmentation of the vascular wall is important for the prevention, diagnosis and treatment of vascular diseases. However, existing methods have inaccurate localization of the vascular wall boundary.

PLoS ONE, 2017 Background HIV-infected individuals are at increased risk of tissue inflammation and accelerated vascular aging (‘inflamm-aging’). Abnormal diurnal blood pressure (BP) rhythms such as non-dipping may contribute to an increased risk of cardiovascular and ...

Artery Research, 2016 Objectives: It is widely thought that excess pulsatile pressure energy from increased stiffness of large central arteries (macro-vasculature) is transmitted to capillary networks (micro-vasculature) and causes end-organ damage (i.e. kidneys).

Association between antibodies to carbamylated proteins and subclinical atherosclerosis in rheumatoid arthritis patients [PDF]
, 2017 BACKGROUND: Rheumatoid arthritis (RA) patients carry a high risk of cardiovascular morbidity and mortality. The excess of cardiovascular disease cannot be entirely explained by traditional risk factors and the immune system contributes to the development

Substrate Stiffness Changes Cell Rolling and Adhesion over L-selectin Coated Surface in a Viscous Shear Flow [PDF]
arXiv, 2019 Understanding the rolling and adhesion behavior of a cell on the vascular surface under viscous shear flow is important to better understand many biological processes. One of the important examples is the adhesion of the leukocytes onto sites of an inflammation.

New Horizons of Arterial Stiffness Developed Using Cardio-Ankle Vascular Index (CAVI)
Journal of atherosclerosis and thrombosis, 2020 Arterial stiffness is recognized mainly as an indicator of arteriosclerosis and a predictor of cardiovascular events. Cardio-ankle vascular index (CAVI), which reflects arterial stiffness from the origin of the aorta to the ankle, was developed in 2004 ...
