Sentence examples for diffusion tight from inspiring English sources

In addition to controlling the paracellular diffusion, tight junctions prevent the diffusion of membrane proteins and lipids between the apical and the basolateral plasma membrane domains [ 3].

This has provided new ideas for the study of the micro-mechanisms of molecular diffusion of tight gas.

Despite these many pathways for absorption, the delivery of drugs to brain is limited because of selective nature of BBB for passive and facilitated diffusion, rigid tight junction, active transport proteins for efflux of amphiphilic molecules.

In this study, we quantitatively investigated the ionic diffusion through these tight junctions.

By contrast, the inner membrane is a tight diffusion barrier to all ions and molecules.

The physiological BBB serves as a tight diffusion barrier for small solutes while the neuroimmunological BBB permits transport of macromolecules and diapedesis of immune cells [ 125].

The gradual escape from the transcription stall along the chromosomal flanks also indicates that friction restrictions to DNA twist diffusion, rather than tight topological boundaries, might suffice to confine DNA helical tension along eukaryotic chromatin.

With increasing study of low porosity and permeability reservoir gas, especially on tight gas, diffusion migration is believed as an important way for the gas to migrate and accumulate in tight reservoirs (Liu et al. 2012; Wang et al. 2014).

[36] The majority of CNS drugs enter the brain by transcellular passive diffusion, due to the tight junction structure and limited transport pathways.

The role of molecular diffusion in recovering oil from tight and shale oil reservoirs has been examined in previous work (Chen et al. 2014; Sanchez-Rivera et al. 2015; Wan and Sheng 2015).

However, in the BBB, the paracellular route is blocked by tight junctions, preventing diffusion of even small molecules such as ions and water.
