Anion transport in heart.
Anion transport proteins in mammalian cells participate in a wide variety of cell and intracellular organelle functions, including regulation of electrical activity, pH, volume, and the transport of osmolites and metabolites, and may even play a role in the control of immunological responses, cell migration, cell proliferation, and differentiation. Although significant progress over the past de...
متن کاملEnergy transduction, ion transport and protonmotive force: are they linked?
The chemiosmotic hypothesis is approximately 20 years old. It has been enormously useful, since it has offered a perspective from which we were able to ask questions never asked before. For the first time proton as well as other ion fluxes through membranes were examined from the common point of view of energy transduction. Despite this usefulness, the time has come to examine the tenets of thi...
متن کاملAnion transport and GABA signaling
Whereas activation of GABAA receptors by GABA usually results in a hyperpolarizing influx of chloride into the neuron, the reversed chloride driving force in the immature nervous system results in a depolarizing efflux of chloride. This GABAergic depolarization is deemed to be important for the maturation of the neuronal network. The concept of a developmental GABA switch has mainly been derive...
متن کاملAmmonium Bicarbonate Transport in Anion Exchange Membranes for Salinity Gradient Energy
Many salinity gradient energy technologies such as reverse electrodialysis (RED) rely on highly selective anion transport through polymeric anion exchange membranes. While there is considerable interest in using thermolytic solutions such as ammonium bicarbonate (AmB) in RED processes for closed-loop conversion of heat energy to electricity, little is known about membrane performance in this el...
متن کاملStudy the Transport Properties of Anion and Cation Exchange Membranes toward Various Ions Using Chronopotentiometry
The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...
