It was stated in the introduction to the section on mediated diffusion that the role of plasma membranes in the transport of substances into and out of cells is incontestable and that intracellular adsorption cannot explain a number of phenomena of kinetic nature. It definitely has no ...

These glial cells facilitate brain homeostasis, form myelin and provide neuronal structure and support8, consistent with evidence of RNA transport across and the permeability of the blood–brain barrier16,17 and that some brain regions are in direct contact with the blood18. Similarly, we used ...

Fuel cells are electrochemical devices, so they are not constrained by the maximum thermal (Carnot) efficiency as combustion engines are. Consequently, they can have very high efficiencies in convertingchemical energytoelectrical energy. In the archetypal example of ahydrogen/oxygenproton-exchange membran...
Evidence for two types of mediation of neutral and amino-acid transport in Ehrlich cells. Nature. 1963;197:765-767.Oxender DL and Christensen HN: Evidence for two types of mediation of neutral amino acid transport in Ehrlich cells. Nature 197: 765-767, 1963....
Animal cells contain centrioles and lysosomes. Do animal cells and plant cells have a cell membrane? The cell membrane is found in both plant and animal cells. As its name suggests, it is a membrane that allows select materials in and out of the cell and aids the cell in protection. ...
Cell sheet engineering is a scaffold-free tissue engineering technique that enables the formation of cell-dense tissues without the use of enzymes [8]. The assembly of cells into sheet-like structures facilitates the delivery of a large number of cells to targeted areas. Advancements in material ...

Nucleoside transport regulation in undifferentiated Neuro-2A cells has been studied and found to include Na+-dependent adenosine transport and facilitated diffusion adenosine transport. The latter corresponded to nitrobenzylthioinosine-sensitive nucleoside transport. Short-term treatment of Neuro-2A cells with...
