Hemodynamics in femoro-femoral venovenous extracorporeal membrane oxygenation using large eddy simulations

open access: yesScientific Reports
Venovenous extracorporeal membrane oxygenation (ECMO) is used for support in refractory severe respiratory failure. Venous drainage and return are accomplished through cannulation of patient’s major veins, typically on the neck and/or the groins ...

Hemodynamic characterization of cardiac dysfunction after traumatic brain injury using a controlled cortical impact model in male rats

open access: yesPhysiological Reports, Volume 14, Issue 16, August 2026.
Abstract Traumatic brain injury (TBI) is associated with cardiovascular dysfunction that worsens clinical outcomes, yet the underlying mechanisms are poorly understood. Clinical studies are limited by heterogeneity, highlighting the need for controlled experimental models.

The isolated working guinea pig heart: A functional and electrophysiological characterisation

open access: yesExperimental Physiology, Volume 111, Issue 7, Page 3137-3151, 1 July 2026.
Abstract Small animal isolated perfused hearts have been used for over 150 years for the study of cardiac physiology and pharmacology. The guinea pig heart represents the smallest mammalian heart that replicates key features of the human heart – for example, with respect to cardiac action potential duration, ion channel expression, excitation ...
