Transport of ions during ion implantation

Physical Review E, 1996
An efficient scheme for the description of long-mean-free-path particle transport at a kinetic level has been extended to a case where particle distributions are highly anisotropic: implantation of ions into a solid. The method calculates the scattering rate of particles throughout a region and obtains the particle distribution from the scattering rate.

Extracellular ion transport

Journal of Theoretical Biology, 1980
Abstract It is a misconception to think that extracellular electric currents of biologic origin are carried by all of the ions in the extracellular medium. It is established that, for certain reasonable boundary conditions, only those ion species that are transported across the plasma membranes of the biological system, or that chemically derive from

Enterotoxins and ion transport

Biochemical Society Transactions, 1984
Throughout the world and especially in developing countries acute diarrhoea1 diseases are the single major cause of morbidity and mortality both in humans and farm animals. Bacteria are among the chief causal agents of acute diarrhoeas and although fluid secretion can result from an increase in luminal osmolarity or hydrostatic pressure, the majority ...

Ion-transporting ATPases as ion channels

Naunyn-Schmiedeberg's Archives of Pharmacology, 1998
Ion-transporting ATPases (pumps) hydrolyze ATP to maintain ion gradients across cell membranes. A presupposition for the maintenance of the gradients is that the ionophore of the pump that conducts the ions is accessible only from one of the two surfaces of the plasma membrane at any given time.

Ameloblasts — Ion Transport Function

Journal of Dental Research, 1979
Recent autoradiographic and in vitro studies have produced evidence that the cells of the enamel organ limit the movement of calcium into enamel during the matrix secretion phase, but have no effect on movement of calcium during the maturation phase.

Ion Transport

2023
In this chapter, we discuss another important property of electrolytes, i.e. how ions move in an electrolyte. We start by introducing AC impedance theory as a precise tool to measure ion conductivity, then go on to summarize other important transport properties.

Ion Transport and Radioresistance

2020
Neoplastic transformation is associated with alterations of the ion transports across plasma and intracellular membranes. These alterations are crucial elements of the phenotypical reprogramming of the transformed cells and may promote adaptation to hypoxia, malignant progression, tumor spreading and metastasis, as well as therapy resistance.
