Effects of Ocular Blood Flow Changes on the Efferent Activity of Cat Ciliary Nerves

open access: yesOphthalmic Research, 1985
The efferent activity of the short ciliary nerves was studied in 23 anesthetized cats. Spontaneous activity was recorded in all preparations, and 33% showed a rhythmic discharge. Ipsilateral common carotid occlusion (ICCO) at constant intraocular and arterial pressures changed the discharge frequency in 14 of 33 filaments. Of these, 13 filaments showed

Dendritic Nano‐Based Slippery Coating by Synergistic Mechanical and Electrostatic Interactions with Persistent and Exceptional Combats Thrombosis

open access: yesAdvanced Science, EarlyView.
A novel dendritic nano‐based slippery coating (DNSC), fabricated by encapsulating carboxyl silicone oil within amino dendritic silica nanoparticles and co‐embedding them in an epoxy resin matrix. The dendritic architecture enhances nanoparticle dispersion in the matrix and establishes mechanical interlock.

Screw‐Based Pill for Intelligent Robotic Extraction of Viscous Fluids in Medical Applications

open access: yesAdvanced Intelligent Systems, EarlyView.
Screw‐based pill for intelligent robotic extraction (S‐PIRE) is a magnetically actuated smart capsule with a motorized screw, 3‐axis sensor, and Bluetooth control for site‐specific and minimally invasive remote sampling of viscous fluids, overcoming passive diffusion limitations.

Mimicking Life: Autonomous Oscillating Artificial Cilia Driven by Chemical Power

open access: yesAdvanced Intelligent Systems, EarlyView.
The synthesis and motion analysis of chemically actuated, individually autonomous artificial cilia are presented. Driven by an internal chemical reaction, the self‐driven individual cilia require no external stimuli. They undergo periodic oscillatory motion with a 3D beat pattern and exhibit chemotactic shifts, reminiscent of biological systems.

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

open access: yesCells
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 ...

Wall Drag on Free-Moving Ciliated Micro-Organisms [PDF]

open access: yes, 1973
It is generally assumed that wall drag on free-moving, self-propelled or passively moving micro-organisms is not significant under normal observation conditions. Yet the point at which such drag becomes significant has not been determined quantitatively.

Biological Fluid Mechanics Under the Microscope: A Tribute to John Blake

open access: yes, 2018
John Blake (1947--2016) was a leader in fluid mechanics, his two principal areas of expertise being biological fluid mechanics on microscopic scales and bubble dynamics. He produced leading research and mentored others in both Australia, his home country,

Soft Artificial Ciliary Brush with Integrated Haptic Feedback for Efficient Airway Mucus Cleaning

open access: yesAdvanced Intelligent Systems, EarlyView.
A fundamental mucus cleaning mechanism is reported, which utilizes both artificial cilia mechanical sweeping and suction‐based mucus cleaning. A novel haptic feedback interface for the artificial cilia provides touch feedback on tissue contact, enhancing operator control and safety.

Cadherin‐26 Facilitates Transepithelial Migration of Eosinophils in Eosinophilic Chronic Rhinosinusitis

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Eosinophilic chronic rhinosinusitis with nasal polyps (eCRSwNP) is characterized by persistent sinonasal inflammation and marked eosinophilic infiltration. Although the relationship between eosinophils and NP formation has been extensively studied, the mechanisms governing eosinophil transepithelial migration into the nasal mucosa ...
