Parameter Inference in the Pulmonary Circulation of Mice [PDF]
, 2017 This study focuses on parameter inference in a pulmonary blood cir- culation model for mice. It utilises a fluid dynamics network model that takes selected parameter values and aims to mimic features of the pulmonary haemody- namics under normal ...

Numerical simulation of blood flow and pressure drop in the pulmonary arterial and venous circulation [PDF]
Biomechanics and Modeling in Mechanobiology, 2014 A novel multiscale mathematical and computational model of the pulmonary circulation is presented and used to analyse both arterial and venous pressure and flow. This work is a major advance over previous studies by Olufsen et al. (Ann Biomed Eng 28:1281–

Animal Models and Experimental Medicine, 2022 Background Aberrant expression of microRNAs (miRNAs) has been associated with the pathogenesis of pulmonary hypertension (PH). It is, however, not clear whether miRNAs are involved in estrogen rescue of PH. Methods Fresh plasma samples were prepared from
