A portable analytical chemistry analyzer was used to make field assessments of wild harlequin ducks (Histrionicus histrionicus) in association with telemetry studies of winter survival in Prince William Sound, Alaska. We compared serum chemistry results obtained on-site with results from a traditional laboratory. Particular attention was paid to serum glucose and potassium concentrations as pot...

background: it is becoming apparent that although inhibition of cholinesterase plays a key role in organophosphate (op) toxicity, other factors are also important. one of the contributing factors for severity of op poisoning is electrolyte imbalances such as hypokalemia. this study was aimed at evaluating the value of hypokalemia in association with plasma cholinesterase (pche) levels in predic...

Hyperkalemia contributes to significant mortality and limits the use of cardioprotective and renoprotective renin-angiotensin-aldosterone blockers. Current therapies are poorly tolerated and not always effective. Here we conducted a phase 2 randomized, double-blind, placebo-controlled dose-escalation study to assess safety and efficacy of ZS-9. This oral selective cation exchanger that preferen...

Objective: To ascertain the role of serum potassium levels in predicting clinical outcomes in diarrhea-associated hemolytic uremic syndrome (HUS D+). Methods: We reviewed clinical and laboratory data from HUS D+ patients at our tertiary care institution from 2001 to 2008. Serum potassium concentration at presentation and during the acute phase of acute renal failure were recorded and related to...

One hundred and six patients with acute myocardial infarction admitted to hospital within four hours after the onset of symptoms were randomised to treatment with intravenous timolol (54 patients) or placebo (52 patients). Serum potassium concentrations were estimated at frequent intervals during the first 24 hours of admission. Patients in both treatment groups, who did not receive subsequent ...

We observed that change in body posture from the supine to the erect position in normal volunteers was associated with a rise in circulating potassium and a fall in sodium concentrations, irrespective of whether the electrolytes were measured in serum or plasma, or whether head-up tilt or ambulation was used. In patients with primary aldosteronism, the fall in serum sodium and rise in serum pot...

Serum and potassium deprivation-induced neuronal death on the primary culture of rat cerebellar granule neurons is being widely used as an in vitro model of neurodegeneration and neuronal apoptosis. In our experiments, serum and potassium deprivation for 12 h induced neuronal death in approximately 20% of cerebellar granule neurons as demonstrated by Trypan Blue assay. Neuronal death was accomp...

DIFFERENCES have been noted between normotensive and hypertensive individuals in salt intake,' intracellular electrolytes,2 total body electrolytes,3 serum electrolytes,4 and the renal excretion of sodium and water.5 If changes in serum sodium concentration reflected intracelluar or metabolic alterations in electrolyte balance, an easily determined factor would be available for study of electro...

Abstract Background Neonatal hyperbilirubinemia (NH) is among the common neonatal morbidities. Phototherapy its most used therapeutic intervention. Different delivering systems and types are currently available. This study aimed to detect compare effects of different phototherapy on serum electrolytes blood glucose effect duration them. Results Five hundred healthy newborns with indirect NH wer...
