Paramecium, a Model to Study Ciliary Beating and Ciliogenesis: Insights From Cutting-Edge Approaches

Frontiers in Cell and Developmental Biology, 2022
Cilia are ubiquitous and highly conserved extensions that endow the cell with motility and sensory functions. They were present in the first eukaryotes and conserved throughout evolution (Carvalho-Santos et al., 2011).

Basalin is an evolutionarily unconstrained protein revealed via a conserved role in flagellum basal plate function

eLife, 2019
Most motile flagella have an axoneme that contains nine outer microtubule doublets and a central pair (CP) of microtubules. The CP coordinates the flagellar beat and defects in CP projections are associated with motility defects and human disease. The CP

Superresolution Microscopy Reveals Distinct Phosphoinositide Subdomains Within the Cilia Transition Zone

Frontiers in Cell and Developmental Biology, 2021
Primary cilia are evolutionary conserved microtubule-based organelles that protrude from the surface of most mammalian cells. Phosphoinositides (PI) are membrane-associated signaling lipids that regulate numerous cellular events via the recruitment of ...

Cell wall pectin and its methyl-esterification in transition zone determine Al resistance in cultivars of pea (Pisum sativum)

Frontiers in Plant Science, 2016
The initial response of plants to aluminum (Al) is the inhibition of root elongation, while the transition zone is the most Al sensitive zone in the root apex, which may sense the presence of Al and regulate the responses of root to Al toxicity.

Developmental nuclear localization and quantification of GFP-tagged EB1c in Arabidopsis root using light-sheet microscopy

Frontiers in Plant Science, 2016
The development of the root apex is determined by progress of cells from the meristematic region to the successive post-mitotic developmental zones for transition, cell elongation and final cell differentiation.

Akimotoite to perovskite phase transition in MgSiO3 [PDF]

, 2004
The akimotoite to perovskite phase transition of MgSiO3 is shown by first principles calculations to have a negative Clapeyron slope, consistent with experimental observations.

Influence of a Modified Weir Profile on Velocity Field and Dissipation Rate in Stepped Spillways: A Comparative Study Using Physical Models and Computational Fluid Dynamics [PDF]

Journal of Applied Fluid Mechanics
Stepped spillways are specialized hydraulic structures crafted to optimize the effective dissipation of hydraulic energy along stepped chutes. The central objective is to scrutinize and improve the mitigation of flow separation occurring from the ogee ...

Estimating the effect of permeability variability of undersaturated oil reservoirs on the change in the start water-cut of well production

Известия высших учебных заведений: Нефть и газ, 2020
The development of undersaturated oil layered heterogeneous oil reservoirs against the background of a general depletion of oil reserves is becoming increasingly interesting.

Geophysical characterisation of the ocean–continent transition at magma-poor rifted margins [PDF]

, 2009
Geophysical characterisation of the ocean-continent transition (OCT) at magma-poor riftedmargins has focused primarily on the determination of P wave velocities using wide-angleseismic techniques. Such experiments have shown that the OCT is heterogeneous,

Characterization of Human Transition Zone Reveals a Putative Progenitor-Enriched Niche of Corneal Endothelium

Cells, 2019
The corneal endothelium regulates corneal hydration to maintain the transparency of cornea. Lacking regenerative capacity, corneal endothelial cell loss due to aging and diseases can lead to corneal edema and vision loss.
