Mathematical Modeling of Mucociliary Clearance: A Mini-Review

Cells, 2019
Mucociliary clearance is an important innate host defense of the mammalian respiratory system, as it traps foreign substances, including pollutants, pathogens, and allergens, and transports them out of the airway.

Metachronal motion of artificial magnetic cilia [PDF]

Soft Matter, 2018,14, 3689-3693, 2018
Organisms use hair-like cilia that beat in a metachronal fashion to actively transport fluid and suspended particles. Metachronal motion emerges due to a phase difference between beating cycles of neighboring cilia and appears as traveling waves propagating along ciliary carpet.

The many-body reciprocal theorem and swimmer hydrodynamics [PDF]

, 2015
We present a reinterpretation and extension of the reciprocal theorem for swimmers, extending its application from the motion of a single swimmer in an unbounded domain to the general setting, giving results for both swimmer interactions and general ...

Effect of Cilia Orientation in Metachronal Transport of Microparticles [PDF]

, 2017
A biomimetic approach is used to generate a directed transversal transportation of micron-sized particles in liquids based on the principle of cilia-type arrays in coordinated motion.

Modelling mucociliary clearance [PDF]

, 2008
Mathematical modelling of the fluid mechanics of mucociliary clearance (MCC) is reviewed and future challenges for researchers are discussed. The morphology of the bronchial and tracheal airway surface liquid (ASL) and ciliated epithelium are briefly ...

Fractional Burgers Fluid Flow Due to Metachronal Ciliary Motion in an Inclined Tube

Frontiers in Physiology, 2019
Cilia-induced flow of fractional Burgers fluid is studied in an inclined tube for both symplectic and antiplectic wave patterns. The solution of the problem is persued under the long wave length limitation.

Influence of radially magnetic field properties in a peristaltic flow with internal heat generation: Numerical treatment

Case Studies in Thermal Engineering, 2021
This article investigates the impact of radially varying magnetic field during the peristaltically flowing nanofluid in a finite flexible tube. The inner surface of axisymmetric tube is filled with metachronal waves of cilia. Flow is provoked as a result

Fluid flow due to collective non-reciprocal motion of symmetrically-beating artificial cilia [PDF]

, 2012
Using a magneto-mechanical solid-fluid numerical model for permanently magnetic artificial cilia, we show that the metachronal motion of symmetrically beating cilia establishes a net pressure gradient in the direction of the metachronal wave, which ...

Pathogenesis of chronic rhinosinusitis with nasal polyps: role of IL-6 in airway epithelial cell dysfunction

Journal of Translational Medicine, 2020
Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by an alteration in airway epithelial cell functions including barrier function, wound repair mechanisms, mucociliary clearance.
