...Anne Myrthe C. van Vliet; Liffert Vogt; Bigina N.R. Ginos; Petra Frings-Meuthen; Martina Heer; Rik H.G. Olde Engberink Introduction: Long-term sodium balance studies show that sodium can be temporarily stored and released in tissues, mediated by circaseptan rhythms of aldosterone and cortisol...

...Karl Marius Brobak; Toralf Melsom; Bjørn Odvar Eriksen; Aud Høieggen; Jon Viljar Norvik; Marit Dahl Solbu Introduction: Subclinical kidney dysfunction may contribute to salt-sensitive hypertension. We assessed the association between the urinary sodium-potassium ratio (Na/K ratio) and blood...

...Veronika Moor; Robert Wagner; Michael Sayer; Marlies Petsch; Sandra Rueb; Hans-Ulrich Häring; Nils Heyne; Ferruh Artunc Background: Adequate removal of sodium (Na) and phosphorus (P) is of paramount importance for patients with dialysis-dependent kidney disease can easily quantified in peritoneal...

...Jianwei Xu; Xiaorong Chen; Zeng Ge; Hao Liang; Liuxia Yan; Xiaolei Guo; Yongqing Zhang; Linhong Wang; Jixiang Ma Background/Aims: High sodium intake and low intake of potassium can increase blood pressure (BP) and risk of developing hypertension. Few studies have examined the association between 24...

... the association of common genetic variants in the SGK1 gene with BP responses to controlled dietary sodium or potassium interventions. Methods: A total of 334 subjects from 124 families were recruited from the rural areas of northern China. After a three-day baseline observation, they were sequentially maintained...

...I. Drenjančević-Perić; B. Jelaković; J.H. Lombard; M.P. Kunert; A. Kibel; M. Gros A high-salt diet is one of the major risk factors in the development and maintenance of hypertension. Numerous experimental and observational studies have confirmed the association of sodium intake with blood pressure...

...Peter Hansell; Örjan Källskog; Mats Wolgast Dopamine (DA) is a natriuretic hormone synthesized in the kidneys by conversion of filtered 3,4-dihydroxyphenylalanine ( L -Dopa), and is activated during hypervolaemia and increased dietary sodium intake. The natriuretic activity of endogenous DA...

...Steven Cachero; Judith B. Van Liew; Leonard G. Feld The renal handling of sodium and calcium in spontaneously hypertensive rats (SHR) was investigated over an extended period (10-75 weeks of age) and compared with age-matched normotensive Wistar-Kyoto controls. The animals were fed a standard rat...

...Norman L.M. Wong; Gary A. Quamme Two-phase recollection micropuncture experiments were performed on female New Zealand rabbits to investigate the effect of flow rate (volume-expansion) compared to reabsorptive rate (furosemide) on calcium and sodium handling along the nephron. Group 1 (n = 6...

... on the presence of bicarbonate and of sodium, whereas it is unaffected by complete removal of extracellular chloride. The observations may point to parallel loss of potassium through potassium channels as well as of bicarbonate and sodium via a bicarbonate-sodium cotransport. Alternatively, potassium/hydrogen ion...

... on the non-diffusible solutes. The content of diffusible solutes is determined by the electrochemical gradients driving them across the plasma membrane and the availability and activity of transport pathways in the membrane. The classical view that the sodium pump offsets passive leaks must be modified...

...J. Graf; P. Haddad; D. Haeussinger; F. Lang The maintenance of liver cell volume in isotonic extracellular fluid requires the continuous supply of energy: sodium is extruded in exchange for potassium by the sodium/potassium ATPase, conductive potassium efflux creates a cell-negative membrane...
