Traumatic Brain Injury-Induced Ependymal Ciliary Loss Decreases Cerebral Spinal Fluid Flow [PDF]

Journal of Neurotrauma, 2014
Traumatic brain injury (TBI) afflicts up to 2 million people annually in the United States and is the primary cause of death and disability in young adults and children.

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.

The Effect of Vasopressin on Ciliary Blood Flow and Aqueous Flow [PDF]

Investigative Ophthalmology and 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

A new index for characterizing micro-bead motion in a flow induced by ciliary beating: Part I, experimental analysis.

PLoS Computational Biology, 2017
Mucociliary clearance is one of the major lines of defense of the respiratory system. The mucus layer coating the pulmonary airways is moved along and out of the lung by the activity of motile cilia, thus expelling the particles trapped in it.

A new index for characterizing micro-bead motion in a flow induced by ciliary beating: Part II, modeling

PLoS Comput. Biol., 2017
Mucociliary clearance is one of the major lines of defense of the human respiratory system. The mucus layer coating the airways is constantly moved along and out of the lung by the activity of motile cilia, expelling at the same time particles trapped in

Ciliary peristalsis flow of hydromagnetic Sutterby nanofluid through symmetric channel: Viscous dissipation in case of variable electrical conductivity

Engineering Science and Technology, an International Journal
For the sperm to have the best chance of reaching the egg, the ciliated walls of the uterine tube must be meticulously monitored. Recognizing the significance of this investigation, a novel mathematical simulation of this process has been performed by ...

Effects of long-acting muscarinic antagonists on promoting ciliary function in airway epithelium

BMC Pulmonary Medicine, 2022
Background Mucociliary clearance (MCC) is an essential defense mechanism in airway epithelia for removing pathogens from the respiratory tract. Impaired ciliary functions and MCC have been demonstrated in asthma and chronic obstructive pulmonary disease (

Influenza A virus enhances ciliary activity and mucociliary clearance via TLR3 in airway epithelium

Respiratory Research, 2020
Background Viral respiratory tract infections, such as influenza A virus (IAV), are common and life-threatening illnesses worldwide. The mechanisms by which viruses are removed from the respiratory tract are indispensable for airway host defense ...
