Potassium deprivation: a systems approach.
THE AMMONIA CONTINGENT WITHIN the renal research community has always faced a challenge of scholarship in discussing the significance of their results. The context of any particular observation easily includes the entire nephron, proximal tubule, loop of Henle, and most distal segments, the pathophysiological conditions of acidosis, hyperand hypokalemia, and all of the various K transporters on...
متن کاملMetabolic acidosis accompanying potassium deprivation.
BURNELL, JAMES M., ELIZABETH J. TEUBNER, AND DAVID P. SIMPSON. bfetabolic acidosis accompanying potasszum deprivation. Am. J. Physiol. 227(2): 329-333. 1974.-Removal of potassium, with or without substitution of an equivalent amount of sodium, from the diet of dogs causes a prompt and persistent decrease in distal H+ secretion resulting in an increase in urine pH. The sequelae to this change in...
متن کاملA Counting Approach for Measuring Multidimensional Deprivation
This paper is concerned with the problem of ranking and quantifying the extent of deprivation exhibited by multidimensional distributions, where the multiple attributes in which an individual can be deprived are represented by dichotomized variables. To this end we first aggregate deprivation for each individual into a “deprivation count” indicating the number of dimensions for which the indivi...
متن کاملEarly polyuria and urinary concentrating defect in potassium deprivation.
The time course of the onset of nephrogenic diabetes insipidus and its relationship to aquaporin-2 (AQP2) expression in K(+) deprivation (KD) remains unknown. Rats were fed a K(+)-free diet and killed after 12 h, 1, 2, 3, 6, or 21 days. Serum K(+) concentration was decreased only after, but not before, 3 days of a K(+)-free diet. Urine osmolality, however, decreased as early as 12 h of KD (1,06...
متن کاملControls Neuronal Apoptosis Triggered by Microtubule Breakdown or Potassium Deprivation
Background: Early loss of neurites followed by delayed damage of neuronal somata is a feature of several neurodegenerative diseases. Death by apoptosis would ensure the rapid removal of injured neurons, whereas conditions that prevent apoptosis may facilitate the persistence of damaged cells and favor inflammation and disease progression. Materials and Methods: Cultures of cerebellar granule ce...
