bananas are climacteric fruits and controlling ripening is effective in reducing loss. this experiment studied the effect of packaging (plastic bag, edible wax and plastic bag, plastic bag and 2 or 4 g/kg potassium permanganate) over 5 weeks of cold storage on the quality and characteristics of cavendish cultivar bananas. the samples were removed from storage at 8, 16, 24, 32 and 40 days and fr...

background and aims . the aim of this study was to evaluate the clinical desensitizing effects of potassium nitrate and strontium acetate in reduction of hypersensitivity. materials and methods . thirty eight patients who presented dental hypersensitivity were selected and randomly allo-cated into two groups. group i: patients who were treated by potassium nitrate 5% foam, and group ii: patient...

acute toxicity (96h-lc50) of potassium permanganate (pm) was determined for caspian kutum rutilus frisii kutum at two size classes (1 and 3 g). static renewal method was used. fish were exposed to different concentrations of pm and mortality was recorded thereafter, until 96 h. exposed fish showed behavioral stress indicators. 96h-lc50 was calculated to be 3.204 (3.147-3.260) mg/l for small fis...

a case study was carried out to see the impacts of shrimp culture on the surface (pond) and ground water (tube-well) quality in three coastal sub-districts of bagherhat sadar, rampal and morrelganj of bangladesh. the people of rampal (100%), morrelgonj (87.5%) and bagherhat (75.5%) expressed that salinity of both surface and ground water increased after shrimp culture, and water becomes more tu...

The constant association of a fall in concentration of serum potassium with attacks of muscular weakness, plus the relief of the weakness by the administration of potassium salts, have clearly indicated that familial periodic paralysis involves a defect in potassium metabolism. The nature of this is not completely understood. Following the observation that the concentration of potassium in seru...

cant correlation between plasma aldosterone and plasma potassium concentration (r = +0.74, P < 0.001) and between changes in the concentration of plasma aldosterone occurring in individual patients and the corresponding changes in plasma potassium concentration (r = +0.52, P < 0.01). There was no significant change in plasma sodium concentration, and plasma corticoid concentration, which was mo...

INTRODUCTION The relationship between potassium regulation and outcome is not known. Our first aim in the present study was to determine the relationship between potassium level and variability in (ICU) stay and outcome. The second aim was to evaluate the impact of a computer-assisted potassium regulation protocol. METHODS We performed a retrospective before-after study including all patients...

Potassium deprivation leads to large reductions in plant growth and yields. How plants sense and transduce the stress signals initiated by potassium deprivation is poorly understood. Both ethylene production and the transcription of genes involved in ethylene biosynthesis increase when plants are deprived of potassium. To elucidate the role of ethylene in low potassium signaling pathways, we us...

Hyperkalaemia, an elevated extracellular fluid potassium concentration, is a common electrolyte disorder and is present in 1-10% of hospitalised patients. Elevated serum potassium concentrations are usually asymptomatic but may be associated with electrocardiogram (ECG) changes. Hyperkalaemia occasionally leads to life-threatening cardiac arrhythmias. Prompt recognition of this disorder, patien...

Studies were performed on normal human subjects to determine the effects of potassium depletion on urine acidification. Depletion was induced by ingestion of a low potassium diet either alone or in combination with a potassium-binding resin, and the response of each subject to an acute ammonium chloride load in the potassium-depleted state was compared to his normal response. Urine pH was signi...
