Point torque representations of ciliary flows [PDF]
arXiv, 2023 Ciliary flows are generated by a vast array of eukaryotic organisms, from unicellular algae to mammals, and occur in a range of different geometrical configurations. We employ a point torque -- or `rotlet' -- model to capture the time-averaged ciliary flow above a planar rigid wall. We demonstrate the advantages (i.e.

Coral physiology: Going with the ciliary flow [PDF]
Current Biology, 2022 Corals have long been known to generate local fluid flows using ciliary beating, but the importance of these ciliary flows is just being discovered. Two new papers shed light on how ciliary-flow physics plays a key role in shaping coral physiology.

Physiological flow of Carreau fluid due to ciliary motion [PDF]
AIP Advances, 2016 In this paper, we have explained the ciliary motion of a Carreau fluid inside a symmetrical channel with ciliated walls. Carreau fluid equations for the two dimensional channel are interpreted by employing the low Reynolds number and long wave-length ...

The ciliary flow sensor and polycystic kidney disease. [PDF]
Nephrol Dial Transplant, 2013 Since the discovery that proteins mutated in different forms of polycystic kidney disease (PKD) are tightly associated with primary cilia, strong efforts have been made to define the role of this organelle in the pathogenesis of cyst formation. Cilia are

The Effect of Vasopressin on Ciliary Blood Flow and Aqueous Flow [PDF]
Investigative Opthalmology & Visual Science, 2013 PURPOSE Previous experiments have shown that arginine-vasopressin (AVP) reduces intraocular pressure (IOP) dose-dependently. The present study investigated the relationships between IOP, ciliary blood flow (CilBF), and aqueous flow (AqF) responses to AVP

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.

Electroosmotically actuated peristaltic-ciliary flow of propylene glycol + water conveying titania nanoparticles. [PDF]
Sci Rep, 2023 The main focus of this article is to mathematically formulate the microfluidics-based mechanical system for nanofluids. A 50:50 mixture of propylene glycol (PG) and water is used as a heat transfer fluid because of its tremendous anti-freezing properties,

MHD Effects on Ciliary-Induced Peristaltic Flow Coatings with Rheological Hybrid Nanofluid [PDF]
Coatings, 2020 Present theoretical investigation is a mathematical illustration of an application to endoscopy by incorporating hybrid nanoparticles and an induced magnetic field with a rheological fluid model for more realistic results.

Ciliary Beating Compartmentalizes Cerebrospinal Fluid Flow in the Brain and Regulates Ventricular Development [PDF]
Current Biology, 2019 Motile cilia are miniature, propeller-like extensions, emanating from many cell types across the body. Their coordinated beating generates a directional fluid flow, which is essential for various biological processes, from respiration to reproduction.

Ciliary blood flow and aqueous humor production [PDF]
Progress in Retinal and Eye Research, 2010 Aqueous humor production is a metabolically active process sustained by the delivery of oxygen and nutrients and removal of metabolic waste by the ciliary circulation. This article describes our investigations into the relationship between ciliary blood flow and aqueous humor production.
