MCMC methods for inference in a mathematical model of pulmonary circulation [PDF]

arXiv, 2018
This study performs parameter inference in a partial differential equations system of pulmonary circulation. We use a fluid dynamics network model that takes selected parameter values and mimics the behaviour of the pulmonary haemodynamics under normal physiological and pathological conditions.

Rod‐shaped Polymerized Salicylic Acid Particles Modulate Neutrophil Transendothelial Migration in Acute Inflammation

Advanced Healthcare Materials, EarlyView.
Rod‐shaped particles outperform spherical particles of the same volume in preventing neutrophil infiltration to inflamed areas, both in vitro and in vivo. This therapeutic effectiveness is attributed to better cell targeting and decreased cell motility, resulting from the geometry‐driven phagocytosis and inhibited actin polymerization.

Pulmonary blood flow and pulmonary hypertension: Is the pulmonary circulation flowophobic or flowophilic?

Pulmonary Circulation, 2012
Increased pulmonary blood flow (PBF) is widely thought to provoke pulmonary vascular obstructive disease (PVO), but the impact of wall shear stress in the lung is actually poorly defined. We examined information from patients having cardiac lesions which

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

Designing for Degradation: Transient Devices Enabled by (Nano)Cellulose

Advanced Materials, EarlyView.
Recent progress in transient devices enabled by (nano)cellulosic materials is reviewed. Transiency mechanisms, advantages of nanocelluloses, and a suite of applications are discussed. A circular thinking approach coupled with life cycle assessment is applied to critically revisit the potential, advantages, and challenges of nanocellulose‐enabled ...

Primary Graft Dysfunction after LungTransplantation [PDF]

, 2014
__Abstract__ The human body requires oxygen to perform aerobic processes 1-3. The lungs are the respiratory organs that not only supply oxygen to the blood, but also remove carbon dioxide from the body.
