Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

Developmental Dynamics, EarlyView.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Molecular anatomy of emerging Xenopus left–right organizer at successive developmental stages

Developmental Dynamics, EarlyView.
Abstract Background Vertebrate left–right symmetry breaking is preceded by formation of left–right organizer. In Amphibian, this structure is formed by gastrocoel roof plate, which emerges from superficial suprablastoporal cells. GRP is subdivided into medial area, which generates leftward flow by rotating monocilia and lateral Nodal1 expressing areas,

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.

BMP4 regulates asymmetric Pkd2 distribution in mouse nodal immotile cilia and ciliary mechanosensing required for left–right determination

Developmental Dynamics, EarlyView.
Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Generic theory of colloidal transport

, 2008
We discuss the motion of colloidal particles relative to a two component fluid consisting of solvent and solute. Particle motion can result from (i) net body forces on the particle due to external fields such as gravity; (ii) slip velocities on the ...

Dynamics of Bio‐Convection Two‐Phase Nanofluid Flow in an Entropy‐Optimized Non‐Newtonian Model With Nonlinear Thermal Radiation and Electromagnetic Effects

Energy Science &Engineering, EarlyView.
ABSTRACT The study of nanofluids has attracted significant attention due to their superior thermophysical properties, making them ideal for thermal transport in engineering and biomedical applications. Motivated by these capabilities, this study develops a novel three‐dimensional mathematical model for electrically conducting Sutterby nanofluids ...

Pathways to Progressive Disability in Multiple Sclerosis: The Role of Glial Cells in Chronic CNS Inflammation

Glia, EarlyView.
ABSTRACT Multiple sclerosis (MS) is the most common non‐infectious inflammatory CNS disease, characterized by progressive neurodegeneration and focal demyelinated lesions. Traditionally considered an autoimmune disease, MS is driven by the immune system's attack on CNS myelin, resulting in cumulative disability.

Diverse Subpopulations of Reactive Astrocytes Following Chronic Toxoplasma Infection

Glia, EarlyView.
Toxoplasma infection results in distinct astrocyte subpopulations. Chronically labeled reactive astrocytes appear transcriptionally plastic and can regain acute inflammatory responding and naive homeostatic astrocytic gene patterns in the presence of ongoing neuroinflammation.

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,

Monitoring Euplotes species dynamics in mixed experiments using genetic markers for quantitative polymerase chain reaction

Limnology and Oceanography: Methods, EarlyView.
Abstract Ciliates are widespread and play a major role in ecosystems as they form an important link between primary producers and higher trophic levels. They have been used as a classic model to study predator–prey interactions of co‐evolutionary processes.
