Phase-resolved dynamic wavefront imaging of cilia metachronal waves. [PDF]
Quant Imaging Med Surg, 2023 The coordination and the directional order of ciliary metachronal waves are the major factors that determine the effectiveness of mucociliary clearance (MCC). Even though metachronal waves play an essential part in immune response, clinical diagnostic tools and imaging techniques that can reliably and efficiently capture their spatial distribution and ...

Emergence of Metachronal Waves in Active Microtubule Arrays [PDF]
Phys. Rev. Fluids 4, 103101 (2019), 2018 The physical mechanism behind the spontaneous formation of metachronal waves in microtubule arrays in a low Reynolds number fluid has been of interest for the past several years, yet is still not well understood. We present a model implementing the hydrodynamic coupling hypothesis from first principles, and use this model to simulate kinesin-driven ...

Hydromechanical properties of metachronal swimming in polychaetes [PDF]
Scientific ReportsFree-swimming polychaetes are common in marine habitats and exhibit a unique form of swimming whereby a metachronal wave occurs simultaneously with a bending body wave.

Direction selection of metachronal waves in hydrodynamic coordination of cilia [PDF]
arXiv, 2023 Large arrays of active cilia coordinate their beat cycles into metachronal waves. These waves can travel in different directions with respect to the cilium's beat direction and the resulting direction of fluid propulsion. Hydrodynamic interactions provide a mechanism for the individual cilia to coordinate their beat cycles.

Unraveling metachronal wave effects on heat and mass transfer in Non-Newtonian fluid
Case Studies in Thermal EngineeringNon-Newtonian fluids flow generated by “cilia” are critical in medicine and bio-medical engineering. Such investigations are created by the back-and-forth movement of a microscopic hair-like structure connected to the walls, which causes a metachronal ...

Curved Surfaces Induce Metachronal Motion of Microscopic Magnetic Cilia. [PDF]
ACS Appl Mater InterfacesCilia are hair-like organelles present on cell surfaces. They often exhibit a collective wave-like motion that can enhance fluid or particle transportation function, known as metachronal motion.

A multiscale biophysical model gives quantized metachronal waves in a lattice of beating cilia. [PDF]
Proc Natl Acad Sci U S A, 2022 Motile cilia are slender, hair-like cellular appendages that spontaneously oscillate under the action of internal molecular motors and are typically found in dense arrays. These active filaments coordinate their beating to generate metachronal waves that drive long-range fluid transport and locomotion.

Emergence of metachronal waves in a chain of symmetrically beating filaments [PDF]
arXivRecent experiments have shown that metachronal waves (MCWs) can emerge from a chain of symmetrically beating nematodes aligned at the edge of sessile droplets. Our study, employing a coupled elastohydrodynamic model of active filaments, elucidates that a misalignment caused by a tilt against the bounding wall disrupts the synchronization and generates ...

Transport efficiency of metachronal waves in 3d cilia arrays immersed in a two-phase flow [PDF]
Journal of Fluid Mechanics, 2017 The present work reports the formation and the characterization of antipleptic and symplectic metachronal waves in 3D cilia arrays immersed in a two-fluid environment, with a viscosity ratio of 20. A coupled lattice-Boltzmann-Immersed-Boundary solver is used. The periciliary layer is confined between the epithelial surface and the mucus.
