Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

Computer Methods in Biomechanics & Biomedical Engineering 13, 5 (2010) 625-640, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

The role of sex differences in cardiovascular, metabolic, and immune functions in health and disease: a review for "Sex Differences in Health Awareness Day". [PDF]

Biol Sex Differ
Sexual dimorphism is a fundamental characteristic of the anatomy and physiology of animals and humans, yet biomedical research has largely ignored these phenomena in the study of health and disease, despite early studies in the eighteenth and nineteenth ...

The Variation in the Diastolic Period with Interventricular Septal Displacement and Its Relation to the Right Ventricular Function in Pulmonary Hypertension: A Preliminary Cardiac Magnetic Resonance Study

Diagnostics, 2022
Background: Pulmonary hypertension (PH) is known to alter the biventricular shape and temporal phases of the cardiac cycle. The presence of interventricular septal (IVS) displacement has been associated with the severity of PH.

Unifying Cardiovascular Modelling with Deep Reinforcement Learning for Uncertainty Aware Control of Sepsis Treatment [PDF]

, 2021
Sepsis is a potentially life threatening inflammatory response to infection or severe tissue damage. It has a highly variable clinical course, requiring constant monitoring of the patient's state to guide the management of intravenous fluids and vasopressors, among other interventions.
