Enterotoxins and ion transport
Biochemical Society Transactions, 1984Throughout 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, 1998Ion-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, 1979Recent 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.

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
2020Neoplastic 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.

Insecticides affecting ion transport
Pharmacology & Therapeutics, 1979Abstract Ion transport phenomena have been reviewed and shown to be an integral part of many physiological processes in the nervous system including peripheral nerve, synaptic junctions and neuromuscular connections. Many instances where insecticides have been demonstrated by neurophysiological and/or biochemical techniques to interfere with ion ...

Active ion transport by mitochondria
Protoplasma, 1967The ability of isolated mitochondria to accumulate very large amounts of Ca++ by an active transport mechanism was discovered by V a s i n g t o n and M u r p h y in 1961 [1]. The accumulation process was found to be blocked by respiratory inhibitors and by uncouplers of oxidative phosphorylation, and thus was completely dependent on electron transport

Transport Energy – Lithium Ion Batteries
2014This chapter focuses on the technological status and most common chemistries of lithium ion batteries. According to IEA, in the year 2012, the global stock of plug-in hybrid electric vehicles (PEHVs) and electric vehicles (EVs) amounted to more than 18 0000, representing only 0.02 % of all vehicles.

Ion Transport in Excitable Cells
Protoplasma, 1967All the available evidence indicates that there are two different and entirely distinct pathways by which sodium and (potassium ions can cross the membranes of nerve and muscle fibres—the excitability mechanism and the pump (or recovery) mechanism. The two types of channel for the passage of cations exist side by side in the membrane, but as can be ...
