Maxi-K channels contribute to urinary potassium excretion in the ROMK-deficient mouse model of Type II Bartter's syndrome and in adaptation to a high-K diet
Type II Bartter's syndrome is a hereditary hypokalemic renal salt-wasting disorder caused by mutations in the ROMK channel (Kir1.1; Kcnj1), mediating potassium recycling in the thick ascending limb of Henle's loop (TAL) ...
Anelastic spectroscopy in potassium aluminum metaphosphate glasses
Anelastic spectroscopy (internal friction and the dynamic modulus) was measured by means of a torsion pendulum at 3-12 Hz, in the range of 100-300 K, for a KAP metaphosphate glass. Two thermally activated internal friction ...
Sodium and Potassium Consumption in a Semi-Urban Area in Peru: Evaluation of a Population-Based 24-Hour Urine Collection
Despite the negative effects of high sodium and low potassium consumption on cardiovascular health, their consumption has not been quantified in sites undergoing urbanization. We aimed to determine the sodium and potassium ...
Efficiency of the fused magnesium potassium phosphate for soybean.
(In: WORLD FERTILIZER CONGRESS OF CIEC, 16., 2014, Rio de Janeiro. Technological innovation for a sustainable tropical agriculture: proceedings. Rio de Janeiro: International Scientific Centre of Fertilizers, 2014. p. 305-307., 2014)
Photosynthetic pigments, nitrogen status, and flower behavior in eggplant exposed to different sources and levels of potassium
The aim of this study was to investigate (i) the influence of different sources and levels of potassium on photosynthetic pigments, (ii) measure nitrogen status in leaf, (iii) evaluate flower behavior in eggplant (Solanum ...
Potassium leaching from millet straw as affected by rainfall and potassium rates
Pearl millet (Penisetum glaucum) is an interesting species to be used as cover crop in tropical areas, showing a high ability in potassium uptake. Potassium (K) is not linked to organic compounds in the plant, and can ...
Further studies on the relationship between potassium and sodium levels and adrenocortical activity
Steroid production in vitro by dog adrenal cortical slices was measured in the presence of varying concentrations of sodium and potassium ions. Increasing concentrations of potassium produced a signincant increase in the ...
Effect of potassium on nutritional status and productivity of peanuts in succession with sugarcane
(Soc Chilena Ciencia Suelo, 2015-01-01)
Potassium contained in sugarcane straw quickly returns to the soil in a form readily available to crops. Thus, the objective of this study was to evaluate the effect of potassium on the nutritional status and grain yield ...
Determination of potassium ions in biodiesel using a nickel(II) hexacyanoferrate-modified electrode
(Elsevier B.V., 2008-02-15)
in this work. nickel hexacyanoferrate-modified electrode was developed to determine potassium ions in biodiesel by potentiometry. The modified electrodes exhibit a linear response to potassium ions in the concentration ...
