in order to study the effects of potassium application on uptake and allocation of nitrogen and seed protein on two lentil cultivars in rain-fed condition a factorial experiment based on randomized complete block design with three replications was conducted at ardabil research center for agriculture and natural resources, in 2008. three potassium levels (0, 30 and 60 kg.ha-1), three nitrogen le...
background: application of potassium ferrate is a chemical oxidation approach used for water and wastewater treatment. the aim of this study is to apply central composite design (ccd) and response surface methodology (rsm) to optimize potassium ferrate consumption in the treatment of wastewater from carpet industries. methods: samples in this experimental study were collected from wastewater, o...
Serum potassium is routinely measured at admission for acute heart failure (AHF), but information on association with clinical variables and prognosis is limited. Potassium measurements at admission were available in 1,867 patients with AHF in the original cohort of 2,033 patients included in the Patients Hospitalized with acute heart failure and Volume Overload to Assess Treatment Effect on Co...
Regulation of intracellular and extracellular potassium concentration is a fundamental process vital for cellular metabolism. Potassium intake, from the diet, is carefully balanced with excretion of potassium via the renal tract and gastrointestinal losses. Following a potassium load, extra-renal buffering of potassium occurs in peripheral tissues prior to its excretion. Thus potassium regulati...
This study evaluated the effects of sodium chloride reduction and replacement with potassium chloride or modified potassium chloride based salts using a weight or molar equivalent basis on the sensory and physico-chemical properties of pork sausage patties. Three independent replications of pork sausage patties were manufactured to compare five treatments: full sodium, reduced sodium, modified ...
Giebisch, Gerhard. Renal potassium transport: mechanisms and regulation. Am. J. Physiol. 274 (Renal Physiol. 43): F817–F833, 1998.— The regulation of potassium metabolism involves mechanisms for the appropriate distribution between the intraand extracellular fluid compartments and for the excretion by the kidney. Clearance and singlenephron studies show that renal excretion is determined by reg...
This study was carried out in order to evaluate the changes of Nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of Leonardite and foliar application of N and K. The experiment was conducted in Gorgan University of Agricultural Sciences and Natural Resources during 2013- 2014. The experiment was laid out a using split-plot arrangement based ...
ATP-sensitive potassium (KATP) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. There has been considerable interest in exploring KATP channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. The purpose of this study was to synthesize 3,3,6,6-tet...
Background and purpose: According to the confirmed dangerous side effects of chemical preservatives such potassium sorbate in public health and food safety, accurate monitoring of the presence of preservatives in food is necessary. Since, according to Iran national standard, using potassium sorbate in dough as preservative is prohibited, so, this study aimed to investigate the presence of pota...
Potassium is the most abundant nutrition element in the surface soil but most of the potassium is unavailable to the plants. The present study was conducted with the aim of isolation of potassium solubilizing bacteria from rhizosphere soil and evaluation of quantitative ability of released potassium from different sources of silicate by strains. For this propose, laboratory and greenhouse evalu...
