Comparison of a Miniaturized Implantable Two‐Stage Rotodynamic Blood Pump to Equivalent Single‐Stage Concepts

Artificial Organs, EarlyView.
This study aims to evaluate the potential of a multistage pump design to enhance hemocompatibility in left ventricular assist devices. We found that the two‐stage concept offers favorable hemolysis measures compared to single‐stage designs, as the reduction in peak shear stresses outweighs the disadvantage associated with prolonged residence time ...

A noncanonical role for Jagged1 in endothelial mechanotransduction

The FEBS Journal, EarlyView.
This study reveals a noncanonical role for Jagged1 in endothelial mechanotransduction. Shear stress modulates Jagged1 expression and subcellular localization. Loss of Jagged1 attenuates mechanotransduction and reduces Src, VEGFR2, and ERK signaling. Direct mechanical stimulation of Jagged1 induces activation of these signaling pathways.

Atlantic salmon (Salmo salar L.) kelt rheotaxis and position choice are influenced by flow velocity and turbulence in a regulated river

Journal of Fish Biology, EarlyView.
Abstract The migratory behaviour of Atlantic salmon kelts is poorly understood. Due to the Atlantic salmon's considerable socio‐economic and ecological importance, their precipitous population abundance declines, and the population resilience potential of salmon kelts, addressing these knowledge gaps is important.

Reduced order modelling of air‐puff test for corneal material characterisation

Journal of Microscopy, EarlyView.
Abstract Models of the fluid–structure interaction (FSI) model for the air‐puff test were analysed. Using Abaqus, the air‐puff test is applied to eyes with varying biomechanical parameters, such as material properties, corneal thickness, and radius.

Comprehensive Study on Quantitative Evaluation of Oral Muscle Tissue in Children With Low Tongue Posture Using Cone Beam Computed Tomography: A Comprehensive Study on Nasal Ventilation Conditions Using Computational Fluid Dynamics

Journal of Oral Rehabilitation, EarlyView.
Measurement of nasal airway computed fluid dynamics, muscle‐fat tissue analysis in this study. Four typical examples illustrating the relationship between low tongue posture, nasal ventilation condition, and perioral muscle‐fat tissue are demonstrated in this study. A.
