A novel mathematical modeling with solution for movement of fluid through ciliary caused metachronal waves in a channel

Scientific Reports, 2021
In the present research, a novel mathematical model for the motion of cilia using non-linear rheological fluid in a symmetric channel is developed.

Ciliary motility activity measurement using a dense optical flow algorithm

2013 35th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2013
Persistent respiratory syncytial virus (RSV) infections have been associated with the exacerbation of chronic inflammatory diseases, including chronic obstructive pulmonary disease (COPD). This virus infects the respiratory epithelium, leading to chronic inflammation, and induces the release of mucins and the loss of cilia activity, two factors that ...

Interfacial Yield Stress Response in Synthetic Mucin Solutions

Advanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

Magnetoelastic Sensing: A Study of Flexible Magnetoelastic Strain Sensors for Highly Deformed Posture Perception

Advanced Materials Technologies, EarlyView.
This study proposes a magnetoelastic strain sensor for highly deformed posture perception. The sensor can maintain stable sensing signal output under significant strain (200%) and at varying stretch rates (ranging from 1000 to 8000 mm min−1). The sensor design is simple and can be applied to soft robots and wearable devices.

Ciliary extracellular vesicles are distinct from the cytosolic extracellular vesicles

Journal of Extracellular Vesicles, 2021
Extracellular vesicles (EVs) are cell‐derived membrane vesicles that are released into the extracellular space. EVs encapsulate key proteins and mediate intercellular signalling pathways. Recently, primary cilia have been shown to release EVs under fluid‐

The effects of temperature and anesthetic agents on ciliary function in murine respiratory epithelia

Frontiers in Pediatrics, 2014
Background: Mucus transport mediated by motile cilia in the airway is an important defense mechanism for prevention of respiratory infections. As cilia motility can be depressed by hypothermia or exposure to anesthetics, in this study we investigated the

Histone Deacetylase 6 (HDAC6) in Ciliopathies: Emerging Insights and Therapeutic Implications

Advanced Science, EarlyView.
HDAC6 regulates primary cilia, crucial for cellular signalling and environmental responses. Dysregulation of HDAC6 contributes to ciliopathies, affecting multiple organs. This review examines HDAC6's role in ciliogenesis, its interaction with signaling molecules, and its potential as a therapeutic target.

Activation of adenosine A_2B receptors enhances ciliary beat frequency in mouse lateral ventricle ependymal cells

Cerebrospinal Fluid Research, 2009
Background Ependymal cells form a protective monolayer between the brain parenchyma and cerebrospinal fluid (CSF). They possess motile cilia important for directing the flow of CSF through the ventricular system.
