Ideally, some of the pores in 3D scaffold transplanted in vivo should remain open to allow nutrient diffusion as the neo-tissue forms [15].
The nicotinic receptor is a channel protein that, upon binding by acetylcholine, opens to allow diffusion of cations.
Exposure of dentin is not sufficient to cause hypersensitivity; the corresponding dentinal tubules must be open to allow for fluid diffusion.
Although the disc diffusion method of antimicrobial sensitivity testing has been described as a reliable, easy and inexpensive method of evaluating antimicrobial efficacy [ 8], recent research has indicated that the results from the disc diffusion test are open to interpretive error and that it is only useful as a preliminary screen for susceptibility testing [ 9].
In contrast, if the protein were switched open to form a water wire, then diffusion-limited conductance would be expected.
Extravasation of a variety of morphological tracers has been observed in epineurial vasculature and attributed to diffusion through both open interendothelial clefts and fenestrated vessels [ 108].
The conformational changes during binding occur mainly in TM α-helices 1, 4, 7 and 10 that cause the occlusion by the intracellular α-helices to open, thereby permitting diffusion [ 12].
A temperature time scaling approach, previously reported for open jet diffusion flames, proved to be a useful tool for comparison of NOx emissions from highly diluted furnace environments regardless of the furnace/burner geometries.
It is evident that the nature of the isotherms at temperatures below the glass transition temperature T g corresponds to the character of the open Warburg diffusion impedance (direct linear relationship) that describes a semi-infinite diffusion process and due to the 'frosting process' of charge transfer in such systems.
Here we report the first such open diffusion experiment to be completed in monkeys.
