Solitons in cell membranes

Physical Review E, 1995
The other equation of the set resembles an equation derived from the Nernst-Planck equation, which describes transmembrane ion transport and hence provides a mechanism for transmembrane potential variation. A more complete calculation of the velocity of the asymptotic wave form shows a lower wave speed than the estimate of Nagumo {ital et} {ital al ...

The First Cell Membranes

Astrobiology, 2002
Organic compounds are synthesized in the interstellar medium and can be delivered to planetary surfaces such as the early Earth, where they mix with endogenous species. Some of these compounds are amphiphilic, having polar and nonpolar groups on the same molecule.

Cell membrane‐mediated cytolysis by membranes from noncytolytic cells

European Journal of Immunology, 1978
AbstractCytolysis was obtained with plasma membrane fractions prepared not only from cytolytic T cells, but also from nonimmune lymphoid cells and, moreover, from cell lines of nonlymphoid origin displaying no lytic ability. Furthermore, no relationship exists between the genetic specificity of T cell‐mediated cytolysis and the activity of membrane ...

Cholesterol and the cell membrane

Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes, 1985
Recent studies concerning cholesterol, its behavior and its roles in cell growth provide important new clues to the role of this fascinating molecule in normal and pathological states.

Affinity chromatography of cells and cell membranes

Journal of Chromatography A, 1980
This article attempts to introduce the concept of cellular affinity chromatography as it departs from molecular affinity chromatography. Special emphasis is placed on the selectio of a solid support as well as on the role of lectins as affinity ligands.

The cell membrane and membrane proteins

2018
This chapter talks about biological membranes that have a lipid bilayer structure made up of a variety of different lipids held together by noncovalent bonds. It shows that lipids are arranged with their hydrophobic tails pointing to the middle of the bilayer and their hydrophilic sections to the outside.

Electropermeabilization of the Cell Membrane

2014
Membrane electropermeabilization is the observation that the permeability of a cell membrane can be transiently increased when a micro-millisecond external electric field pulse is applied on a cell suspension or on a tissue. Applicative aspects for the transfer of foreign molecules (macromolecules) into the cytoplasm are routinely used.

Water Channels In Cell Membranes

Annual Review of Physiology, 1992
Although water moves through the lipid domain of all biological membranes, there is strong evidence that facilitated or channel-mediated water transport exists in a number of cell plasma membranes and intracellular vesicles (l0, 37). The kidney proximal tubule contains water transporters in the cell apical and basolateral plasma membranes to facilitate
