Effects of Flow Hydrodynamics and Eye Movements on Intraocular Drug Clearance
Pharmaceutics, 2022 New in vitro prototypes (PK-Eye™) were tested with and without eye movement to understand diffusion and convection effects on intraocular clearance. Port placement in front ((i) ciliary inflow model) and behind the model lens ((ii) posterior inflow model)

Ccdc11 is a novel centriolar satellite protein essential for ciliogenesis and establishment of left-right asymmetry [PDF]
, 2016 The establishment of left–right (L-R) asymmetry in vertebrates is dependent on the sensory and motile functions of cilia during embryogenesis. Mutations in CCDC11 disrupt L-R asymmetry and cause congenital heart disease in humans, yet the molecular and ...

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

Ciliomotor circuitry underlying whole-body coordination of ciliary activity in the Platynereis larva
eLife, 2017 Ciliated surfaces harbouring synchronously beating cilia can generate fluid flow or drive locomotion. In ciliary swimmers, ciliary beating, arrests, and changes in beat frequency are often coordinated across extended or discontinuous surfaces.

Reynolds number limits for jet propulsion: A numerical study of simplified jellyfish [PDF]
, 2010 The Scallop Theorem states that reciprocal methods of locomotion, such as jet propulsion or paddling, will not work in Stokes flow (Reynolds number = 0).

A role for Gle1, a regulator of DEAD-box RNA helicases, at centrosomes and basal bodies. [PDF]
, 2017 Control of organellar assembly and function is critical to eukaryotic homeostasis and survival. Gle1 is a highly conserved regulator of RNA-dependent DEAD-box ATPase proteins, with critical roles in both mRNA export and translation.

Ciliary motility activity measurement using a dense optical flow algorithm
2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013 Persistent respiratory syncytial virus (RSV) infections have been associated with the exacerbation of chronic inflammatory diseases, including chronic obstructive pulmonary disease (COPD). This virus infects the respiratory epithelium, leading to chronic inflammation, and induces the release of mucins and the loss of cilia activity, two factors that ...

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
