Physicochemical characteristics also influence the degree to which a drug is able to cross a barrier layer, and the route by which it does this; whether transcellular (across the cells -by diffusion, cells -byediffusionansport or transcarrier-mediatedellular-by diffusing transporthe tight junctiors between the cells.
Science
We sought a way to quantify how tight or diffuse the 'distribution of each transcription start site: whether there was a single, well defined, start site or a series of alternative start sites spread over a given area.
Science
Shown are the anterior mRNAs fs(1 K10 and milt (examples for diffuse-anterior and tight-anterior localization) and the and posterior mRNA vkg and zpg (examples for diffuse-posterior and tight-posterior).
Science
Anterior and posterior RNA localization varied between diffuse (fs(1 N, yemalpha ) and tight cortical enrichments (Lcp65Ac, mus210 ).
Science
The most plausible explanation is that the Ig molecules did not diffuse as easy through the tight junctions as BSA, under normal permeability conditions.
Of the tight, intermediate and diffuse TSS regions, 72.3% (3293), 46.8% (2171) and 25.0% (2197) were within 500 bp upstream of annotated genes.
Science

widely restricted
Emphasizes the broad nature of a restriction, contrasting with the idea of something being narrowly confined.
sparsely confined
Highlights the scattered nature of something within a limited space.
distributed narrowly
Focuses on the act of spreading something out but within a limited scope.
spread thinly but firmly
Combines the idea of a wide distribution with a sense of stability or control.
extensive yet contained

scattered and controlled
Implies a deliberate spreading of something that remains managed or regulated.
unfocused restriction
This captures the sense of restriction but applies it to something that lacks clear focus. It changes the primary meaning.
dispersed imprisonment
