In the human body, particles and ions that cannot cross the cell membrane use carrier proteins to get into and out of the cell. Each carrier protein accepts only one type of particle or ion to transport either into or out of the cell. Read Facilitated Diffusion | Overview, Importance & ...
We measured the diffusion coefficient of myoglobin ( D Mb ) inside mammalian skeletal muscle cells with a microinjection technique. A small bolus of horse ... S Papadopoulos,KD Jürgens,G Gros - 《Pflügers Archiv》 被引量: 90发表: 1995年 Myoglobin levels in individual human skeletal muscle ...

When compared to control rats fed a commercial diet with 23% protein, early malnourished rats showed deficits in body and brain weights (10% to 60% and 3% to 15%, respectively), as well as increases in velocity of SD propagation (10% to 20%). These effects were directly related to ...
A haptic interaction technique for volume images based on gradient diffusion The manual step in semi-automatic segmentation of medical volume images typically involves initialization procedures such as placement of seed-points or po... E Vidholm,I Nystrom 被引量: 22发表: 2005年 Diagnostic Palpation...
, in Human Biochemistry, 2018 Facilitated Diffusion This is a modified version of osmosis where a proteinaceous channel is used for the solute to enter a cell from the extracellular space but energy is not required, similarly to free diffusion. Here, molecules will move into the cell based on...
Passive & Active Transport in Cells from Chapter 3 / Lesson 2 69K Passive and active transport are vital for the movement of nutrients and other substances in a cell. Discover the tiny world of cell transport with the concentration gradient, simple diffusion, facilitated diffusion, osmosis, an...
Writing in Nature in 1939, Chaik and Duthie suggested, "… it seemed to us likely that it was an enzyme acting on some substrate in the skin, causing the removal of a barrier to the rapid diffusion of intradermally injected fluids."14 The enzyme activity was subsequently defined as a ...
PDESOLV and its associated subroutines were then used to numerically validate previously published models of oxygen diffusion in the capillaries of the human body, and to test the sensitivity of these models to initial conditions and knot placement.;PDESOLV was also applied to the very stiff ...
