Sentence examples for barrier at the base from inspiring English sources
Transfer of fluorescent protein between the flagellum and the plasma membrane is compromised, however, suggesting the presence of a diffusion barrier at the base of the Leishmania flagellum.
If the soft barrier at the base of region I is effective, melts could accumulate there, increasing porosity above the constant value of 1% assumed here.
Our Science paper provided evidence for a diffusion barrier at the base of the cilium between the ciliary membrane and apical plasma membrane.
There is some speculation about the existence of such a diffusion barrier at the base of cilia; however, recent reports suggest that septin2 is part of a diffusion barrier at the base of the ciliary membrane (Hu et al., 2010) and that plasma membrane proteins are anchored to the cortical actin cytoskeleton to restrict their movement to primary cilia (Breslow and Nachury, 2011).
In principle, D1Rs could be concentrated on cilia relative to the extra-ciliary plasma membrane by immobilization or by a diffusion barrier at the base of the cilium (Huang et al., 2007; Hu et al., 2010; Francis et al., 2011).
Rfx2 also controlled the expression of the planar cell polarity (PCP) effector gene fritz/ wdpcp, which encodes a protein governing assembly of the septin diffusion barrier at the base of cilia (Kim et al., 2010).
This process results in partial dissolution of the pore inner wall surface and in the dissolution of the inverted barrier layer at the base of each pore.
A direct consequence of the voltage rise was a thickening of the barrier layer at the base of the porous anodic film.
Current changes after each voltage ramp to Vhigh are observed along with sequential origination of pits, pores and tubes in a compact barrier layer at the base of oxide film.
In some tubules of SCARKO mice, hypertonicity-induced shrinkage of centrally located cells was seen despite clear signs of (partial) barrier formation at the base of the tubules (Figure 1H).
Specifically, a barrier formed at the base of region I for the fast-spreading case shown in Figure 10 would produce a steep sided, highly conductive triangle similar to that observed in the MT data.
