Flow Field Analysis of Micromixer Powered by Ciliary Motion of Vorticella
Electronics and Communications in Japan, 2012SUMMARYThe use of cilia from microorganisms requires design of the channel and the fabrication process. We developed a method of injecting Vorticella into a microchamber and exploited the properties of Vorticella as a micromixer of two solutions. We characterized a flow field generated by the ciliary motion of Vorticella.

The role of ciliary blood flow and ultrafiltration in aqueous humor formation
Experimental Eye Research, 1973Abstract The purpose of this paper is to discuss the role played by transepithelial ultrafiltration in the formation of aqueous humor. Much of the discussion is based on published data. To give weight to conclusions some experiments were performed on rabbits, cats and monkeys. It is shown in rabbits that the normal difference in mean pressure between

Automatic analysis of ciliary beat frequency using optical flow
SPIE Proceedings, 2012Ciliary beat frequency (CBF) can be a useful parameter for diagnosis of several diseases, as e.g. primary ciliary dyskinesia. (PCD). CBF computation is usually done using manual evaluation of high speed video sequences, a tedious, observer dependent, and not very accurate procedure.

Numerical Heat Transfer, Part B Fundamentals
Cilia motion is commonly located in mammalian cells of living organisms which continually grow and feature conspicuously. The ciliary apparatus is associated with cell cycle movement and proliferation, and cilia play a dynamic part in human and animal ...

Numerical Simulation of Flow Fields and Particle Trajectories in Ciliary Suspension Feeding
Bulletin of Mathematical Biology, 2000A model describing the ciliary driven flow and motion of suspended particles in downstream suspension feeders is developed. The quasi-steady Stokes equations for creeping flow are solved numerically in an unbounded fluid domain around cylindrical bodies using a boundary integral formulation.

Anterior ciliary venous blood flow and oxygen saturation at reduced arterial pressure
American Journal of Physiology-Legacy Content, 1963Flow and oxygen saturation of blood in the anterior ciliary vein of the dog eye were measured as arterial pressure was reduced. Blood flow showed a proportional reduction with reduction in arterial pressure. In this respect this vascular bed behaves, in general, as a rigid tube system over the range of arterial pressures examined.

A Method for Determination in Vivo of the Rate of Ciliary Best and Mucous Flow in the Trachea
Acta Physiologica Scandinavica, 1955Summary.A method is described by which simultaneous determination can be made of the rate of ciliary beat and that of the tracheal flow of mucus in small living mammals (rats and guinea pigs). The body temperature and the temperature and humidity of the environmental air can be varied.

Experimental Eye Research, 1980
The anterior portion of the eye receives arterial blood from two circulations. One circulation is external to the globe—the anterior ciliary arteries; the other is internal to it—the long posterior ciliary arteries. This study determined the percentage contribution to anterior segment blood flow by anterior ciliary arteries in primates by the reference
