Diffusion is the passive movement of molecules from an area of high concentration to an area of low concentration whereas osmosis is the movement of a solvent such as water from an area of low solute concentration to an area of high concentration o...

A combination of agar dilution and disk diffusion known as the antimicrobial gradient method is commercially available under the name Etest® and allows to determine the MIC of a compound using diffusion techniques. By impregnating a strip with different concentrations of an antimicrobial compound, t...
Diffusion of Water Molecules: Water molecules in brain tissue naturally diffuse in a preferred direction along the axonal fibers in white matter. This diffusion is hindered by cellular structures, membranes, and myelin sheaths surrounding axons. Imaging Process: During a DW-MRI scan, multiple images...
In contrast to active transport, facilitated diffusion is a spontaneous passive process, in which the molecules move down a concentration gradient across a biological compartment by specific carrier proteins. Thus, we hypothesized that the water-soluble nsLTPs localized in the cell wall could ...
An overall mechanism for the serial formation of oxygen clusters (Oi)n at T≤ 500 °C has been proposed and these defects might be directly related to TDN centres. A requirement is rapid diffusion of O2 dimers and further evidence for this process should be sought to confirm or reject the...
The neuropil is separated from neuronal cell bodies by ensheathing glia, which as we show using dye injection experiments, contribute to the formation of an internal diffusion barrier. We find that ensheathing glia are polarized with a basolateral plasma membrane rich in phosphatidylinositol-(3,4,5...
Because elemental fractionation in solid state is unlikely in the deep mantle due to extremely slow diffusion (e.g., Hofmann and Hart, 1978), we can reason that processes known to occur in the upper mantle and crust (e.g., magmatism, metamorphism, weathering, transport and sedimentation) ...
In order to extract DNA from polyacrylamide gel, the chopped gel slices were soaked in diffusion buffer (0.5 M ammonium acetate; 10 mM magnesium acetate; 1 mM EDTA, pH8.0; 0.1% SDS), and incubated at 50 °C overnight. The supernatant was collected, residual polyacrylamide removed...
