Some silicate rocks are a rich source of potassium (K), with the possibility for use in agriculture. The present study aimed to evaluate agronomic efficiency index (AEI) nepheline syenite (NS) and phonolite (PN) comparison chloride (KCl) as K maize production. An experiment was conducted greenhouse Ilha Solteira, São Paulo, Brazil. A hybrid grown 8 L pots filled 6 kg soil low concentration cont...

Dietary potassium loading results in rapid kaliuresis, natriuresis, and diuresis associated with reduced phosphorylation (p) of the distal tubule Na(+)-Cl(-) cotransporter (NCC). Decreased NCC-p inhibits NCC-mediated Na(+) reabsorption and shifts Na(+) downstream for reabsorption by epithelial Na(+) channels (ENaC), which can drive K(+) secretion. Whether the signal is initiated by ingesting po...

Methotrexate (MTX) is an accepted regimen for conservative treatment of unruptured ectopic pregnancy. However ,gestational sac greater than 3.5 cm, existence of cardiac activity and high titers of serum beta human chorionic gonadotrophin ( B-HCG) levels are relative contraindications of Mtx treatment. A 29-year-old, gravida 3, parity 1 and a 34-year-old nulliparous women presented with a compla...

We experimentally investigate the filament dynamics of non-Newtonian drops falling under gravity through air, and report the effects of semiilute concentrations of the polyelectrolyte polymer xanthan gum mixed in 80:20 glycerol/water with varying concentrations of potassium chloride KCl). We find that the addition of 780 ppm xanthan gum to the glycerol/water solvent dramatically increases the d...

We report on a method for selective optical sensing and imaging of potassium ions using a sandwich assembly composed of layers of photonic crystals and an ion-selective membrane. This represents a new scheme for sensing ions in that an ionic strength-sensitive photonic crystal hydrogel layer is combined with a K+-selective membrane. The latter consists of plasticized poly(vinyl chloride) doped ...

backgrounds and aims: stroke incidence rate has increased during the past 2 decades. the question of whether calcium, chloride, potassium, sodium levels are associated with stroke has remained controversial. the present study aimed to evaluate the serum levels of potassium, sodium, calcium, and chloride within stroke patients. materials and methods: the study participants consisted of 53 cconse...

The protoplasm of certain cells is able to distinguish electrically between K(+) and Na(+). This has been called the potassium effect. This is illustrated by experiments with Nitella. When 0.01 M KCl which has stood in contact with Nitella is replaced by 0.01 M NaCl the P.D. changes in a positive direction by an amount which varies between 30 and 95 mv. This ability to distinguish between K(+) ...

Background: Nephrotoxicity is one of the major side-effects of cisplatin that has been seen in about 20% of treated patients. The aim of this study was to assess the effectiveness of a forced hydration protocol comprised of isotonic saline, potassium chloride (KCl) and magnesium sulfate (MgSO4) on prevention of cisplatin nephrotoxicity. Methods: This cross sectional prospective study was perfor...
