Secretion was not wasteful since biofilms limited diffusion and digestive enzymes could reach high concentrations.
In that model, we limited diffusion in cytoplasm by reducing apparent diffusion coefficient of ATP and ADP in cytoplasm.
PI3K and PTEN are usually sequestered in distinct lipid groups in the membrane that display limited diffusion and mixing between lipid rafts.
First, limited diffusion tends to cause potential reactants to become more spatially separated than expected under high diffusion and random spatial distribution.
The effectiveness of chemotherapeutic drugs is further reduced by inadequate delivery and limited diffusion through different microenvironments (Jain, 1999; Tannock et al, 2002; Minchinton and Tannock, 2006).
Limited diffusion causes spatial associations between reactants.
Current therapies for glioblastoma are limited by ineffective delivery beyond the blood-brain barrier, limited diffusion of regionally-delivered macromolecules, and lack of tumor specificity.
Why would one set of benefits, "sharing of common goods, protection against external aggression, limited diffusion of molecules, etc".
The XPS depth profiles showed a limited diffusion of Mg towards the ceramic film.
In addition, biodegradation rates are restricted by limited diffusion of oxygen and nutrients to hydrocarbon-degrading aerobes.
This behavior is a result of poor interlayer adhesion from limited diffusion and entanglement of chains across the interlayer interface.
