We describe a method for determining the intracellular ionized magnesium concentration ([Mg2+]i) in platelets by using the fluorescent probe FURAPTRA. We determined the dissociation constant (KD) of FURAPTRA for Mg2+ (2.26 +/- 0.29 mmol/L), within-day assay variability (CV = 6.8%), among-day intraindividual variability (CV = 11.0%), variability after a 4-h delay in processing the blood specimen...

Magnesium batteries are one of the most promising post-lithium technologies. One main challenges preventing its commercialization is to find an efficient and safe electrolyte. The electrolyte, playing role blood in a battery, interacts with all battery components must be highly compatible them. development Cl-free electrolyte systems desired avoid corrosion issues, many studies suggest magnesiu...

An automated method was adapted to measure the concentration of Na and K in plasma, nonhemolyzed whole blood, and hemolyzed whole blood, and thus allow the calculation of erythrocyte electrolyte con.centrations by a modified indirect method. The Na concentrations of nonhemolyzed whole blood and plasma were used to calculate the percent cell volume (hematocrit) of a blood sample. The percent cel...

total parenteral nutrition (tpn) has a vital role in controlling nutritional deficiencies especially in patients with critical conditions who are confined to bed in intensive care unit (icu). complete evaluation of the nutritional status of these patients is necessary to achieve their nutritional goal. the aim of this investigation was to study the complete blood count (cbc), coagulation parame...

Great interest has been centred during recent years on the renal physiology and the milieu interieur of newborn infants. However, so far no studies have been carried out on newborn Bantus. Although it is well established that neonatal renal function is immature (McCance and Young, 1941; McCance, 1959), full-term healthy babies delivered spontaneously and without undue difficulty are known to be...

OBJECTIVES To determine whether acute exercise associated muscle cramping (EAMC) in distance runners is related to changes in serum electrolyte concentrations and hydration status. METHODS A cohort of 72 runners participating in an ultra-distance road race was followed up for the development of EAMC. All subjects were weighed before and immediately after the race. Blood samples were taken bef...

The intended function of dialysate fluid is to correct the composition of uraemic blood to physiologic levels, both by reducing the concentration of uraemic toxins and correcting electrolyte and acid-base abnormalities. This is accomplished principally by formulating a dialysate whose constituent concentrations are set to approximate normal values in the body. Sodium balance is the cornerstone ...

Essential thrombocythemia is very rare during childhood. The pseudo-electrolyte imbalances including hyperkalemia and hypercalcemia have been reported among adult patients with this condition. Due to the rarity of this condition in the pediatric age group, overtreatment and even hospitalization of these patients for correction of electrolyte imbalances is usually inevitable. Herein, we reviewed...
