Ependymal cilia beating induces an actin network to protect centrioles against shear stress
Nature Communications, 2018 Ependymal ciliary beating contributes to the flow of cerebrospinal fluid in the brain ventricles and these cilia resist the flow forces. Here the authors show that the assembly of a dense actin network around the centrioles is induced by cilia beating to

Internal friction controls active ciliary oscillations near the instability threshold [PDF]
Science Advances 6 (33), eabb0503 (2020), 2019 Ciliary oscillations driven by molecular motors cause fluid motion at micron scale. Stable oscillations require a substantial source of dissipation to balance the energy input of motors. Conventionally, it stems from external fluid. We show, in contrast, that external fluid friction is negligible compared to internal elastic stress through a ...

Generic flow profiles induced by a beating cilium [PDF]
Eur. Phys. J. E 35 (2012) 72, 2012 We describe a multipole expansion for the low Reynolds number fluid flows generated by a localized source embedded in a plane with a no-slip boundary condition. It contains 3 independent terms that fall quadratically with the distance and 6 terms that fall with the third power.

Trapping study of nanofluids in an annulus with cilia
AIP Advances, 2015 The main purpose of this article is to present a mathematical model of ciliary motion in an annulus. In this analysis, two dimensional flow of a viscous nanofluid is observed in an annulus with ciliated tips. The current theoretical model may be supposed

Mixing and transport by ciliary carpets: a numerical study [PDF]
Journal of Fluid Mechanics / Volume 743 / March 2014, pp 124 - 14, 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 region below the cilia tip.

Microfluidic pumping using artificial magnetic cilia [PDF]
. Microsystems & Nanoengineering (2018) 4:11, 2018 One of the vital functions of naturally occurring cilia is fluid transport. Biological cilia use spatially asymmetric strokes to generate a net fluid flow that can be utilized for feeding, swimming, and other functions. Biomimetic synthetic cilia with similar asymmetric beating can be useful for fluid manipulations in lab-on-chip devices. In this paper,

Long-term clearance from small airways in subjects with ciliary dysfunction
Respiratory Research, 2006 The objective of this study was to investigate if long-term clearance from small airways is dependent on normal ciliary function. Six young adults with primary ciliary dyskinesia (PCD) inhaled 111 Indium labelled Teflon particles of 4.2 μm geometric and ...
