As noted above, the way the experiments were conducted led to diffusion in a single axis normal to the brain surface that was perfused with radiotracer.
In addition to the singlet of free ferrocene at 4.15 ppm, three small singlets at 0.66, 0.31, and 0.13 ppm were detected in the H spectrum; these led to diffusion coefficients typical for 2-Br and were assigned to FeCp 2@2 aCD 3CN, FeCp 2@2 aCD 2Cl 2 and FeCp 2@2 b d (for details and spectra see Supporting Information).
Further, most business corporations have a marketing division that is the researcher of diffusing new product and statistical research activities that lead to diffusion to help the organisation's advertising endeavours.
We aim to review the main clinical uses of DWI, focusing on the physiological mechanisms that lead to diffusion abnormalities.
Alternatively, direct experiences may lead to diffusion over other channels, such as interest in reports from mass media or face-to-face conversations.
Similar studies have been carried out by Valerio et al. [25], and they have suggested that when higher enzyme concentration is immobilized, the binding sites of the carrier get saturated with enzyme which further leads to diffusion limitation phenomena.
Similarly, does entrapment at parB/ parS lead to diffusion via bead on a string followed by a transition into loops?
However, as the proto-cytoplasm cell surrounds the other cells, it necessarily would grow larger and develop a complicated shape, both of which could lead to diffusion limiting the effects of Ca transported across the cell membrane.
Failure of remyelination in progressive disease is another key difference between relapsing-remitting MS and secondary progressive MS. The state of chronic demyelination leads to diffusion of Na+ channels away from nodes of Ranvier and a subsequent influx of sodium and increased ATP consumption.
In addition, the use of a secreted luciferase may increase the resulting signal, as the substrate no longer requires entry into the cell expressing the luciferase; however, this may also lead to diffusion throughout the body, thus preventing accurate localization of the signal.
The picture emerging from modeling indicates that production of growth factors by cells may lead to diffusion-driven instability, which in turn may lead either to decay of both population, or to emergence of local growth foci represented by spike-like solutions.
