Early life exposure to perfluorooctanesulfonate (PFOS) impacts vital biological processes in Xenopus laevis: Integrated morphometric and transcriptomic analyses

Ecotoxicology and Environmental Safety
Perfluorooctanesulfonate (PFOS) is a ubiquitous environmental pollutant associated with increasing health concerns and environmental hazards. Toxicological analyses of PFOS exposure are hampered by large interspecies variations and limited studies on the

Numerical investigation of cilia beating modulated flow of magnetized viscous fluid in a curved channel with variable thermal conductivity

Alexandria Engineering Journal
Cilia flow plays a crucial role in biological systems such as the movement of mucus in the respiratory tract, circulation of cerebrospinal fluid in the brain, and propulsion of sperm cells.

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.

Theoretical analysis of Reiner-Philippoff fluid flow in two layers due to metachronal propulsion: Subject to surrounding temperature

Case Studies in Thermal Engineering
Mucociliary clearance plays a crucial role within the respiratory system as an initial protective mechanism against infections. Hence, it is imperative to validate any assumptions made regarding the mucociliary clearance and its impact on its ...

Analytical modelling of cillia- driven prandtle fluid flow in a horizontal tube with viscous dissipation using homotopy perturbation method

Results in Engineering
This work analytically investigates the effects of viscous dissipation on cilia-induced Prandtl fluid flow in a horizontal tube. Approximate formulations for temperature and velocity profiles are obtained by solving the governing nonlinear equations ...

Artificial mini-heart

, 2017
Here we report the fabrication of an internal micropump based on magnetically actuated artificial cilia (MAAC) that functions like an artificial mini-heart. The micropump can provide versatile flows in a microfluidic channel network, when the MAAC are actuated to perform a tilted conical movement.

In vitro living system for streaming flow rectification

Physical Review Research
Small—but finite—fluid inertia can be leveraged to generate steady flows out of liquid vibrations around an immersed interface. In engineering, external high-frequency drivers (10^{2}–10^{5}Hz) allow this inertial rectification phenomenon, known as ...

Development of an inhalable contrast agent targeting the respiratory tract mucus layer for pulmonary ultrasonic imaging

Scientific Reports
Impaired mucociliary transport is a distinguishing sign of cystic fibrosis, but current methods of evaluation are invasive or expose young patients to ionizing radiation. Contrast-enhanced ultrasound imaging may provide a feasible alternative.
