Peristaltic-Ciliary Flow of A Casson Fluid through An Inclined Tube

Communication in Biomathematical Sciences, 2021
The paper is concerned with the peristaltic-ciliary transport of a viscoplastic fluid (Casson fluid) through an inclined cylindrical tube. The peristalsis-cilia induced motion is analysed in the moving frame of reference under the lubrication ...

Ultrasound-activated ciliary bands for microrobotic systems inspired by starfish

Nature Communications, 2021
Most engineered ciliary bands generate simple hydrodynamics with unidirectional flow profiles. Here, inspired by the starfish larva, the authors show acoustically-activated microrobots with cilia that can control direction of liquid flow through ...

Reversible Modulation of Motile Cilia by a Benzo[e][1,2,4]triazinone: A Potential Non-Hormonal Approach to Male Contraception [PDF]

Cells
Motile cilia play essential roles in various physiological processes including fluid flow generation and sperm motility. In this study, we identified 1,3-diphenyl-6-(4-phenylpiperazin-1-yl)benzo[e][1,2,4]triazin-7(1H)-one as a potent and reversible ...

Enhancement of convective flow in ternary hybrid nanofluid induced by metachronal propulsion

Advances in Mechanical Engineering, 2023
This paper aims to inspect the mixed convective ciliary transport of ternary hybrid nanofluid through a curved channel having ciliated walls. Titanium oxide, Alumina oxide, and Silicon dioxide nanoparticles are taken for the current problem with blood as

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 ...

Ependymoma associated protein Zfta is expressed in immature ependymal cells but is not essential for ependymal development in mice

Scientific Reports, 2022
The fusion protein of uncharacterised zinc finger translocation associated (ZFTA) and effector transcription factor of tumorigenic NF-κB signalling, RELA (ZFTA-RELA), is expressed in more than two-thirds of supratentorial ependymoma (ST-EPN-RELA), but ...

Cilia proteins are biomarkers of altered flow in the vasculature

JCI Insight, 2022
Cilia, microtubule-based organelles that project from the apical luminal surface of endothelial cells (ECs), are widely regarded as low-flow sensors. Previous reports suggest that upon high shear stress, cilia on the EC surface are lost, and more recent ...
