, 1985 Ammonium is capable of replacing potassium to support the hydrolysis of ATP by the Na-K-ATPase in many tissues. Whether ammonium supports the transport function of the Na-K-ATPase in the kidney (where such a substitution could be physiologically ...

Journal of Neurochemistry, Volume 170, Issue 6, June 2026.Components and properties of Ca2+ buffers in astrocytes, which should be considered for data interpretation and in computational modeling of astrocyte Ca2+ activity. ABSTRACT Astrocytic Ca2+ signaling is essential for maintaining physiological brain function, including the modulation of synaptic transmission, neurovascular coupling, and ion homeostasis.

Plant Biology, Volume 28, Issue 4, Page 1043-1051, June 2026.Potassium silicate can decrease the uptake of sodium (Na+) into wheat cells by affecting the Na+ uptake channels and increasing ion homeostasis. Abstract Salinity causes negative impacts on crops. We investigated the effect of potassium silicate (K2SiO3) on the cytosolic uptake of sodium, [Na+]cyt, in mesophyll protoplasts of wheat cultivars differing ...

Physiological Reports, Volume 14, Issue 11, June 2026.Abstract Heart failure with preserved ejection fraction (HFpEF) is associated with skeletal muscle dysfunction that contributes to exercise intolerance and disease progression. Altered Ca2+ homeostasis and increased oxidative stress have been proposed as mechanisms underlying muscle weakness in HFpEF; however, the effects of aerobic exercise on ...

Physiological Reports, Volume 14, Issue 11, June 2026.Abstract Despite the ubiquitous use of monosodium glutamate (MSG) as a food additive, its specific effects on intestinal health and disease remain largely unclear. Here we found mucosal application of MSG induced an upward intestinal short‐circuit current (Isc) in the murine ileum, which was significantly reduced by extracellular Cl−, Na+, and Ca2 ...

, 1988 Muscle tension recordings were made from earthworm body wall muscle and the action of acetylcholine, cholinomimtics and cholinolytics examined. The effect of cholinergic agents on muscle twitches induced following field stimulation was also investigated.

, 1996 Previous studies have suggested that recovery from pulmonary edema may be dependent on active sodium ion transport. Most of the data supporting this concept came from work done in isolated type II cells, isolated lung preparations, or in models of ...

Bilaterian phylogeny based on analyses of a region of the sodium-potassium ATPase alpha-subunit gene
, 2004 Molecular investigations of deep-level relationships within and among the animal phyla have been hampered by a lack of slowly evolving genes that are amenable to study by molecular systematists.

Thyrotoxic periodic paralysis and polymorphisms of sodium-potassium ATPase genes
, 2006 Objective: Thyrotoxic periodic paralysis (TPP) is a complication of hyperthyroidism association with recurrent, reversible episodes of muscle weakness.
