Simulations of particle tracking in the oligociliated mouse node and implications for left-right symmetry breaking mechanics [PDF]

arXiv, 2019
The concept of internal anatomical asymmetry is familiar; usually in humans the heart is on the left and the liver is on the right, however how does the developing embryo know to produce this consistent laterality? Symmetry breaking initiates with left-right asymmetric cilia-driven fluid mechanics in a small fluid-filled structure called the ventral ...

Transport efficiency of metachronal waves in 3d cilia arrays immersed in a two-phase flow

, 2016
The present work reports the formation and the characterization of antipleptic and symplectic metachronal waves in 3D cilia arrays immersed in a two-fluid environment, with a viscosity ratio of 20.

Sensing Dog Brain Reactions to Smell by AI Speckle Pattern Analysis

Journal of Biophotonics, EarlyView.
The setup of our experiment is shown on Labrador, Johny, a canine participant of our research. The schematic of the setup features: green laser, digital camera, source of smell, and computer. Regions of the brain that were tested are highlighted. Note that the hippocampus and amygdala are on both sides of the dog's brain.

In vitro screening and in vivo evaluation of antiparasitic phytochemicals against Cryptocaryon irritans in pompano, Trachinotus ovatus

Journal of the World Aquaculture Society, Volume 53, Issue 6, Page 1084-1100, December 2022., 2022
Abstract Cryptocaryon irritans, one of the most devastating holotrichous ciliated protozoans, causes massive economic losses in the pompano, Trachinotus ovatus, mariculture industries. Considering the many advantages of phytochemicals, such as low cost, low residuals, and low pollution, they can be a good alternative for the prevention and control of C.

TRPP2 and TRPV4 form a polymodal sensory channel complex [PDF]

, 2008
The primary cilium has evolved as a multifunctional cellular compartment that decorates most vertebrate cells. Cilia sense mechanical stimuli in various organs, but the molecular mechanisms that convert the deflection of cilia into intracellular calcium ...

Mechanisms underlying unidirectional laminar shear stress-mediated Nrf2 activation in endothelial cells: Amplification of low shear stress signaling by primary cilia

Redox Biology, 2021
Endothelial cells are sensitive to mechanical stress and respond differently to oscillatory flow versus unidirectional flow. This review highlights the mechanisms by which a wide range of unidirectional laminar shear stress induces activation of the ...

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.

A Systematic Review of the Variability of Ventilation Defect Percent Generated From Hyperpolarized Noble Gas Pulmonary Magnetic Resonance Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Hyperpolarized (HP) gas pulmonary MR ventilation images are typically quantified using ventilation defect percent (VDP); however, the test‐retest variability of VDP has not been systematically established in multi‐center trials. Herein, we perform a systematic review of the test‐retest literature on the variability of VDP, and similar metrics,

The Interconnected World of Dermatology and Ophthalmology

JEADV Clinical Practice, EarlyView.
ABSTRACT Medicine is a dynamic field that constantly discovers new links between different specialties. Dermatology and Ophthalmology are two related branches of medicine, having many similarities and interactions. The skin and the eyes both encounter various environmental challenges, such as ultraviolet radiation, allergens, infections, and trauma ...
