Vortical ciliary flows actively enhance mass transport in reef corals [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance The fitness of corals and their ability to form large reefs hinge on their capacity to exchange oxygen and nutrients with their environment. Lacking gills or other ventilating organs, corals have been commonly assumed to depend entirely on ambient flow to overcome the mass transport limitations associated with molecular diffusion.

Monitoring airway mucus flow and ciliary activity with optical coherence tomography
Biomedical Optics Express, 2012 Muco-ciliary transport in the human airway is a crucial defense mechanism for removing inhaled pathogens. Optical coherence tomography (OCT) is well-suited to monitor functional dynamics of cilia and mucus on the airway epithelium. Here we demonstrate several OCT-based methods upon an actively transporting in vitro bronchial epithelial model and ex ...

Mixing and transport by ciliary carpets: a numerical study [PDF]
, 2013 We use a 3D computational model to study the fluid transport and mixing due to the beating of an infinite array of cilia. In accord with recent experiments, we observe two distinct regions: a fluid transport region above the cilia and a fluid mixing ...

Cilia proteins are biomarkers of altered flow in the vasculature
JCI Insight, 2022 Cilia, microtubule-based organelles that project from the apical luminal surface of endothelial cells (ECs), are widely regarded as low-flow sensors. Previous reports suggest that upon high shear stress, cilia on the EC surface are lost, and more recent ...

Applied Sciences, 2021 This paper proposes a mathematical analysis of the inertial flow of an MHD second-grade non-Newtonian fluid in a ciliated channel. The two-dimensional flow is modelled under the effect of inertial forces, magnetic field and Darcy’s resistance, which make
