New Journal of Physics, 2017 Using large resolution numerical simulations of gyrokinetic (GK) turbulence, spanning an interval ranging from the end of the fluid scales to the electron gyroradius, we study the energy transfers in the perpendicular direction for a proton–electron ...

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.Prophylactic ureteral stent placement was associated with a reduced risk of urinary tract injury in women with placenta accreta spectrum undergoing peripartum cesarean hysterectomy, independent of prior cesarean number. Abstract Introduction This retrospective cohort study investigated whether preoperative bilateral ureteral stent placement reduces ...

Artificial 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.

Artificial Organs, EarlyView.Shear‐induced blood damage—including hemolysis, platelet and neutrophil injury, and von Willebrand factor (vWF) degradation—was evaluated for the BrioVAD and HM3 using an in vitro circulatory loop under clinically relevant conditions. Across 15 biomarkers (n > 6 per group), no significant differences were observed between the two devices.

Artificial Organs, EarlyView.This study utilized an extensive optimization involving n = 540 design of experiments to produce a superior drainage cannula design. Compared to the clinically used Maquet model, our optimized design demonstrated reduced blood stagnation volumes, increased cannula tip velocities, and higher upper body drainage, potentially minimizing risk of thrombosis

British Journal of Pharmacology, EarlyView.Ischaemic stroke is characterised by acute cerebrovascular occlusion and blood–brain barrier (BBB) breakdown. Our results indicated that the histone deacetylase inhibitor suberoylanilide hydroxamic acid (SAHA) ameliorated the loss of BBB integrity, changed the morphology of brain endothelial cells, increased the level of basement membrane and ...

Frontiers in Astronomy and Space SciencesThe energy dissipation in collisionless plasmas as the solar wind is not yet fully understood. The intermittent nature of magnetic structures appears to be a fundamental part of the energy cascade.

Constrictions and shear stress are key determinants of amyloidogenic light chain (AL) amyloidosis
The FEBS Journal, EarlyView.In this study, we investigate how flow constrictions and shear stress trigger cardiac antibody light chain (AL) fibril formation and deposition. We mimic the mechanical forces exerted by the heart and the microvasculature network using a mini‐peristaltic pump setup and a grid‐type microchannel network, respectively.
