Local well-posedness of a three-dimensional phase-field model for thrombus and blood flow [PDF]
arXiv, 2022 In this article we consider a fluid-structure interactions model on a three dimensional bounded domain, that describes the mechanical interaction between blood flow and a thrombus with Hookean elasticity. The interface between the two phases is given by a smooth transition layer, diffuse with a finite thickness. We derive various a priori estimates and

Non-invasive Inference of Thrombus Material Properties with Physics-informed Neural Networks [PDF]
, 2020 We employ physics-informed neural networks (PINNs) to infer properties of biological materials using synthetic data. In particular, we successfully apply PINNs on inferring the thrombus permeability and visco-elastic modulus from thrombus deformation data, which can be described by the fourth-order Cahn-Hilliard and Navier-Stokes Equations.

Microfluidic flow chambers using reconstituted blood to model hemostasis and platelet transfusion in vitro [PDF]
, 2016 Blood platelets prepared for transfusion gradually lose hemostatic function during storage. Platelet function can be investigated using a variety of (indirect) in vitro experiments, but none of these is as comprehensive as microfluidic flow chambers.

Intracardiac mass: A rare case report
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017 Intracardiac thrombus is seen in many circumstances. Rarely it is found in left atrium in the absence of mitral stenosis. Here we are reporting a case of Cardiomyopathy with thrombus in left ventricle and left atrium.

Platelet G i protein Gα i2 is an essential mediator of thrombo-inflammatory organ damage in mice [PDF]
, 2015 Platelets are crucial for hemostasis and thrombosis and exacerbate tissue injury following ischemia and reperfusion. Important regulators of platelet function are G proteins controlled by seven transmembrane receptors.

Journal of the American College of Cardiology, 2015 A thrombus in transit through a patent foramen ovale (PFO) with impending paradoxical embolism is an extremely rare event. Early detection is a challenge due to its transient nature. 44 year old male with no past medical history presented after a motor vehicle accident.

The value of multimodality imaging for detection, characterisation and management of a wall adhering structure in the right atrium [PDF]
, 2014 The case presents a wall adherent structure in the right atrium in a young patient with peripheral tcell lymphoma followed by successful prolonged lysis therapy resulting in the resolution of the thrombus is presented.

A phase-field system arising from multiscale modeling of thrombus biomechanics in blood vessels: local well-posedness in dimension two [PDF]
arXiv, 2023 We consider a phase-field model which describes the interactions between the blood flow and the thrombus. The latter is supposed to be a viscoelastic material. The potential describing the cohesive energy of the mixture is assumed to be of Flory-Huggins type (i.e. logarithmic). This ensures the boundedness from below of the dissipation energy.
