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.

Regulation of ion transport by microRNAs
Current Opinion in Nephrology & Hypertension, 2011This review aims to describe the recent findings obtained on the regulation of ion transport by microRNAs in physiological and pathological situations in different organs and organisms.The number of ion channels or transporters can be regulated by increasing or decreasing the transcription and/or translation of the corresponding genes. In this context,

Ion Transport and Water Movement
Journal of Dental Research, 1987Secretion of water and electrolytes in salivary glands occurs by a dual process involving the formation of a plasma-like, isotonic primary-secretion in salivary acini and its subsequent modification in salivary-ducts by the removal and addition of specific ions. The mechanisms underlying the formation of primary acinar secretion have been investigated

Ferroelectrics, 1991
Abstract An essential feature of surface stabilized ferroelectric liquid crystal displays (SSFLCD) is their bistability. Experiments and theory show however that this bistability can be destroyed by ionic charges building up at both electrodes. In this article a better understanding of the ion concentration distribution and their transport behavior is ...

The lepidopteran midgut has received intensive study, and from a biophysical point of view is undoubtedly the best understood of insect guts. This chapter will concentrate on movement of ions between midgut lumen and haemolymph. This movement includes absorption of ingested ions from the midgut and, in addition, secretion of ions from haemolymph and ...

Lithium is the lightest metal known, however in nature it exists only as the ion in salts and ores. Lithium has been used medicinally with varying degrees of effectiveness or noneffectiveness in the treatment of a variety of disorders using different chemical forms such as lithium bromide as a hypnotic and sedative agent, lithium chloride as a ...

The inner membrane of the mitochondrion fulfills several crucial roles in cell metabolism. It segregates the enzymes and metabolites of the major energy-yielding metabolic pathways from alternative reactions in the cytosol and, at the same time, provides pathways for regulated interchange of metabolites between the matrix and nonmitochondrial ...
