In the present study, Viola betonicifolia (whole plant) and solvent fractions obtained thereof were evaluated for various micronutrients such as lead, copper, chromium, iron, nickel, zinc, cadmium, cobalt and macronutrients such as sodium, potassium and calcium using atomic absorption spectrophotometer and flame photometry respectively. It was observed that cobalt and cadmium were not detectibl...

Juel, C., H. Pilegaard, J. J. Nielsen, and J. Bangsbo. Interstitial K1 in human skeletal muscle during and after dynamic graded exercise determined by microdialysis. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R400– R406, 2000.—Interstitial K1 concentrations were measured during one-legged knee-extensor exercise by use of microdialysis with probes inserted in the vastus lateralis...

Flammability properties of plasma pretreated cotton fabrics subjected to flame-retardant treatment were studied. Plasma pretreatment, using an atmospheric pressure plasma jet (APPJ), was applied to cotton fabrics to enhance material properties, while retaining inherent advantages of the substrates. An organic phosphorus compound (flame-retardant agent, FR) together with a melamine resin (crossl...

Hyponatremia has been recognized as a clinical entity since the finding by Loeb in 1932 that significantly lowered serum sodium and chloride levels are a characteristic finding in Addison's disease. It soon became apparent with the work of Winkler and Crankshaw in 1938, that hyponatremia was an accompaniment of diverse disease states as repeatedly confirmed since the introduction and clinical a...

We describe a method for measuring plasma, erythrocyte, and leukocyte sodium (Na+), potassium (K+), and magnesium (Mg2+) concentrations in 10-mL blood specimens. After separating cells with Ficoll-Hypaque and washing with isotonic choline chloride, erythrocytes and leukocytes are counted, so that results can be expressed as amount of substance per cell and also to monitor cell integrity and pos...

Column leach test has been performed to examine the behavior of leaching of sodium, calcium and potassium in landfills. In the column leach apparatus, two different layers of contaminated and uncontaminated soils of different height ratios (ratio of depth of contaminated soil to the depth of uncontaminated soil) are taken. Water is poured from an overhead tank at a particular flowrate to the in...

Activities (a) of intracellular K and Na in rabbit ventricular papillary muslces were determined with cation-selectivve glass microelectrodes and concentrations (C) were estimated with flame photometry. The CK and aK of the muscles were 134.9 +/- 3.1 mM (mean value +/- SE) and 82.6 mM, respectively, at 25 degrees C. The corresponding CNa and aNa were 32.7 +/- 2.7 and 5.7, respectively. The appa...

Simultaneous intracellular and sucrose-gap recordings showed, in contrast to previous findings, that the electrical parameters of giant axons were similar to intact and desheathed connectives bathed with the 'extracellular Ringer' of Yamasaki & Narahashi. This implies that the extra-axonal sodium concentration, in situ, is likely to be lower than had been previously supposed. Axonal responses s...

BACKGROUND High salt intake increases blood pressure (BP) and hypertension risk. This study aimed to examine association of urinary sodium excretion with BP and hypertension correlates among Cameroonian pygmies under hunter-gatherer subsistence mode and Bantus, living in urban area under unhealthy behavioral habits. METHODS In this cross-sectional cluster sampling study, we randomly enrolled ...

We propose the late-O, early-B star IRS2b as the ionizing source of the Flame Nebula (NGC 2024). It has been clear that such a hot, massive star must be present in this heavily obscured region, and now it has been identified. New nearinfrared photometry shows that IRS2b is the most luminous and hottest star in the young star cluster embedded in the center of NGC 2024. The near-infrared observat...
