An unusual pattern of Na+ and K+ movements across the horse erythrocyte membrane
(1986)
Marked differences in the activities of three monovalent cation transport systems in horse versus human erythrocytes are reported. Whereas horse erythrocytes exhibit a 6-fold higher sodium-lithium countertransport, the ...

Excess iodide downregulates Na+/I− symporter gene transcription through activation of PI3K/Akt pathway
(Elsevier Ireland, 2016-05)
Transcriptional mechanisms associated with iodide-induced downregulation of NIS expression remain uncertain. Here, we further analyzed the transcriptional regulation of NIS gene expression by excess iodide using PCCl3 ...
Temporal evolution of 137Cs+, K+ and Na+ in fruits of South American tropical species
(Elsevier Science, 2013-02)
Concentrations of 137Cs, K and Na in fruits of lemon (Citrus limon B.) and of K and Na in fruits of coconut (Cocos nucifera L.) trees were measured by both gamma spectrometry and neutron activation analysis, with the aim ...
Actin modifies Ca2+ block of epithelial Na+ channels in planar lipid bilayers
(BIOPHYSICAL SOCIETY, 2001-05)
The mechanism by which the cytoskeletal protein actin affects the conductance of amiloride-sensitive epithelial sodium channels (ENaC) was studied in planar lipid bilayers. In the presence of monomeric actin, we found a ...
