T.he localization of sodium in the avian salt gland by means of an electron-dense precipitate of sodium pyroantimonate was first used by Komnick and Komnick. Recently, Kaye and associates utilized this method to localize sodium in rabbit corneal endothelial cells—normal and ouabain treated. Zadunaisky used modifications of this method to locate the specific sites of sodium ion in the membranous...

Sodium ion influx and outflux were measured sinmltaneously, with two radioactive isotopes, in the cat ciliary body isolated in vitro. Measurements of membrane potential or short-circuit current were made concurrently with the isotope studies. In the non-short-circuited membrane, where the membrane electromotive force assisted sodium influx, the sodium ion current was two to three times larger t...

Physiological ligands of (sodium-potassium)-dependent adenosine triphosphatase influenced the sensitivity of the enzyme to the inhibitor, ouabain. Phosphorylation of the native enzyme is accelerated by sodium ions, while potassium ions accelerate dephosphorylation. Exposure of the phosphoenzyme to ouabain slowed its turnover and rendered it insensitive to potassium ion. This action of ouabain d...

BACKGROUND The difference in sodium ion levels determined with direct and indirect methods often exceeds the permissible limit clinically. Additionally, no previous study has assessed the difference in the sodium ion levels between direct and indirect methods in premature infants. Therefore, the present study aimed to compare sodium ion levels obtained using an arterial blood gas analyzer (ABGA...

Sodium-Ion Batteries In article number 2300002, Yu Li, Chuan Wu, Ying Bai, and co-workers develop an efficient strategy to reconstruct the surface functionality of hard carbons in situ, which can controllably catalyze preferential salt decomposition form inorganic-rich layered solid electrolyte interphase (SEI). The structurally stable ion-conductive SEI enables advanced carbon anodes with ultr...

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...

Sodium-ion batteries are a potentially low-cost and safe alternative to the prevailing lithium-ion battery technology. However, it is a great challenge to achieve fast charging and high power density for most sodium-ion electrodes because of the sluggish sodiation kinetics. Here we demonstrate a high-capacity and high-rate sodium-ion anode based on ultrathin layered tin(II) sulfide nanostructur...

All solid-state sodium batteries (ASSSBs) are considered a promising alternative to lithium-ion due increased safety in employing components and the widespread availability low cost of sodium. As one indispensable battery system, organic liquid electrolytes currently used their high-ionic conductivity (10−2 S cm−1) good wettability; however, low-thermal stability, flammability, leakage tendency...

From the data given above the following explanation of the effects of continued loss of the external secretion of the pancreas may be offered. The underlying event is a steadily increasing deficit of sodium and of chloride ion due to the large requirement for these electrolytes in the construction of pancreatic juice. In consequence there is continued loss of water, chiefly from the body fluids...
