Polypropylene Nanoplastic Exposure to Respiratory Epithelial Barrier‐On‐Chip and Interfacial Interactions With Human Serum Albumin

open access: yesAllergy, EarlyView.
Exposure to 305 nm PP NPs significantly disrupts the airway barrier‐on‐chip, reducing TEER, suppressing ZO‐1/ACE2 expression, and triggering ROS‐mediated apoptosis. In biological media, PP NPs exhibit a biphasic adsorption pattern, leading to the formation of a protein corona that increases their size to 364 nm.

Validation of Aortic Blood Flow Simulations During Extracorporeal Circulation Using Phase Contrast Magnetic Resonance Imaging

open access: yesArtificial Organs, EarlyView.
This is the first study assessing in vivo blood flow profiles during extracorporeal circulation (ECC) scenarios. Magnetic resonance imaging data served for the calibration of computational fluid dynamics algorithms, enabling accurate replication of the hemodynamic conditions.

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

open access: yesArtificial 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 ...

Shaping the Flow: Impact of Blade Shape on Performance and Hemocompatibility in Rotodynamic Blood Pumps

open access: yesArtificial Organs, EarlyView.
Blade shapes (leading‐edge geometry and thickness) in rotodynamic blood pumps were systematically evaluated. Thinner blades improve pump efficiency by reducing blockage effects, while neither blade thickness nor leading‐edge geometry shows clear hemocompatibility benefits. Overall, blade shape has a limited impact on hemocompatibility, indicating it is

Modern Fire Safety Protocols in the Archeological Contexts: A New Tool for Studying the Health and Behavioral Effects of Fire Use in Semi‐Closed Spaces

open access: yesArchaeometry, EarlyView.
ABSTRACT This study evaluates the application of computational fluid dynamics (CFD) simulations, integrated with controlled fire experiments, to investigate combustion processes in semi‐closed spaces. The framework enables systematic modeling of smoke dispersal, particulate transport, and hearth performance under variable morphologies and ventilation ...
