Regulation of proximal bicarbonate reabsorption
American Journal of Physiology-Renal Physiology, 1984Under free-flow conditions, alterations in acid-base and extracellular volume status affect absolute proximal bicarbonate reabsorption. Microperfusion studies have characterized the individual determinants of the active and passive components of proximal acidification.

Renal reabsorption of amino acids
American Journal of Physiology-Legacy Content, 1962Using the method of stop flow analysis an attempt was made to localize the process of amino acid reabsorption in the nephron of the dog. Special attention was given to the group of basic amino acids and cystine believed to share a common tubular transport mechanism. The evidence obtained in this study points clearly to the proximal segment as the site

Magnesium stimulates renal phosphate reabsorption
American Journal of Physiology-Renal Physiology, 2008In the kidney, ∼80% of the filtered phosphate (Pi) is reabsorbed along the proximal tubule. Changes in renal Pireabsorption are associated with modulation of the sodium-dependent Picotransporter type IIa (NaPi-IIa) and type IIc (NaPi-IIc) protein abundance in the brush-border membrane (BBM) of proximal tubule cells.

The assessment of phosphate reabsorption
Clinica Chimica Acta, 1969Abstract The relation for phosphate between the excretion rate (UV) and the plasma concentration [P] has been defined in fasting persons and after an infusion of phosphate when tubular reabsorption is maximal. The results demonstrate that the maximal tubular reabsorption capacity can be predicted with a nomogram from measurements of phosphate and ...

Carbonic anhydrase independent bicarbonate reabsorption
Pfl�gers Archiv European Journal of Physiology, 1982The present study was designed to define the prerequisites of carbonic anhydrase independent bicarbonate reabsorption. In free flow experiments during systemic application of carbonic anhydrase inhibitor benzolamide (50 mg/kg B. W.) bicarbonate recovery in % of filtered load was found to be 74 +/- 8% in late proximal convoluted tubules, 39 +/- 6% in ...

HYPERPARATHYROIDISM AND MAXIMAL GLUCOSE REABSORPTION
Acta Medica Scandinavica, 1971Abstract. The maximal tubular reabsorptive capacity for glucose (TmG) has been determined in patients admitted to the hospital for suspected hyperparathyroidism. One group consisted of 19 cases with proved hyperparathyroidism. The other group consisted of 14 cases with normal serum calcium concentration on repeated determinations, and in four of these

Aspects of Tubular Reabsorption Revisited
Chest, 1970Current concepts as to how reabsorption of filtered fluid occurs in the kidney are discussed. Emphasis is placed on certain unique problems arising from the remarkable covariance of amounts of filtered and reabsorbed. A concept advanced by Carl Ludwig over 100 years ago is exhumed and found to provide a reasonable basis for glomerulotubular balance ...
