Mathematical Model of Volume Kinetics and Renal Function after Burn Injury and Resuscitation [PDF]
Burns, 47(2), pp.371-386 (2021), 2021 This paper presents a mathematical model of blood volume kinetics and renal function in response to burn injury and resuscitation, which is applicable to the development and non-clinical testing of burn resuscitation protocols and algorithms. Prior mathematical models of burn injury and resuscitation are not ideally suited to such applications due to ...

Partial renal coverage in EVAR causes unfavorable renal flow patterns in an infrarenal aneurysm model [PDF]
J.Vasc.Surg 67 (2018) 1585-1594, 2019 Objective: To achieve an optimal sealing zone during EVAR, the intended positioning of the proximal end of the endograft fabric should be as close as possible to the most caudal edge of the renal arteries. Some endografts exhibit a small offset between the radiopaque markers and the proximal fabric edge.

Extremely weakly-supervised blood vessel segmentation with physiologically based synthesis and domain adaptation [PDF]
arXiv, 2023 Accurate analysis and modeling of renal functions require a precise segmentation of the renal blood vessels. Micro-CT scans provide image data at higher resolutions, making more small vessels near the renal cortex visible. Although deep-learning-based methods have shown state-of-the-art performance in automatic blood vessel segmentations, they require ...

Non-invasive optical measurement of arterial blood flow speed [PDF]
arXiv, 2021 Non-invasive measurement of the arterial blood speed gives rise to important healthinformation such as cardio output and blood supplies to vital organs. The magnitude andchange in arterial blood speed are key indicators of the health conditions and development andprogression of diseases.

Time-dependent Clearance of Cyclosporine in Adult Renal Transplant Recipients: A Population Pharmacokinetic Perspective [PDF]
arXiv, 2021 Aim The pharmacokinetic (PK) properties of cyclosporine (CsA) in renal transplant recipients are patient- and time-dependent. Knowledge of this time-related variability is necessary to maintain or achieve CsA target exposure. Here, we aimed to identify factors explaining variabilities in CsA PK properties and characterise time-dependent clearance (CL/F)

Contribution a la modelisation et simulation numerique de l ecoulement du sang dans l artere [PDF]
arXiv, 2009 Numerous are the questionings raised by medicine interventionnelle, concerning the hold in charge of the pathologies of the arterial partition (aneurysm, dissection, coarctation, atherosclerosis).for it we made the modeling and the numeric simulation of the blood flow in the renal artery taken by the Medical imagery.

Relationship between blood pressure and flow rate in arteries using a modified Windkessel model [PDF]
arXiv, 2020 This study examined the flow rate in arteries using the modified Windkessel model, considering various models for blood pressure. An exact solution was derived using a Laplace transform method and the effects of blood pressure on the flow rate in an artery were examined.

Retinal blood flow reversal quantitatively monitored in out-of-plane vessels with laser Doppler holography [PDF]
arXiv, 2020 Laser Doppler holography is a planar blood flow imaging technique recently introduced in ophthalmology to image human retinal and choroidal blood flow non-invasively. Here we present a digital method based on the Doppler spectrum asymmetry that reveals the local direction of blood flow with respect to the optical axis in out-of-plane vessels.

Photoacoustic vector tomography for deep hemodynamic imaging [PDF]
arXiv, 2022 Non-invasive imaging of deep blood vessels for mapping hemodynamics remains an open quest in biomedical optical imaging. Although pure optical imaging techniques offer rich optical contrast of blood and have been reported to measure blood flow, they are generally limited to surface imaging within the optical diffusion limit of about one millimeter ...
