The concentrations of essential elements in the milk of Croatian Coldblood mares and LittoralDinaric donkey were measured. The mean element contents in horse milk were (mg/kg): Ca 687.1, Mg 72.1, K 637.7, Na 143.5, Cu 0.126, Fe 0.235, Se 0.01, Zn 2.06, Mn<0.01. In donkey milk, the mean element contents were (mg/kg): Ca 815.4, Mg 80.8, K 887.7, Na 217.6, Cu 0.027, Fe 0.196, Zn 2.36, Mn 0.016. In...

The effects of chemotherapy [25 mg/kg 1,3-bis(2-chloroethyl)-1-nitrosourea administered with a single i.p. injection] on cellular energetics by P nuclear magnetic resonance (NMR) spectroscopy, total tissue sodium by single-quantum (SQ) Na NMR spectroscopy, and intracellular sodium by triple-quantum-filtered (TQF) Na NMR spectroscopy were studied in the s.c. 9L glioma. Animals were studied by NM...

Chemical precipitation is a useful technology to remove ammonium (NH(4)(+)) from landfill leachate. In this paper, the removal of ammonium from landfill leachate was studied. The objective of this study was to investigate optimum pH, optimum molar ratio, and different kinds of chemicals combinations for magnesium ammonium phosphate (MAP) precipitation. Furthermore, the kinetics of MAP formation...

This paper is concerned with the effect of individual Na+, K+, Mg2+ and Ca2+ ions upon the nutrient dynamics and cell morphology during submerged fermentation of Aspergillus giganteus MTCC 8408 in a medium containing ample soluble starch, corn steep liquor and proteose peptone supply. Nutrient dynamics was elucidated using Taguchi's DOE (design of experiment) L8 orthogonal array (OA) with carbo...

High-resolution (R ≈ 100 000), high signal-to-noise spectra of M71 giants have been obtained with HIRES at the Keck I Telescope in order to measure their Mg isotopic ratios, as well as elemental abundances of C, N, O, Na, Mg, Al, Si, Ca, Ti, Ni, Zr and La. We demonstrate that M71 has two populations, the first having weak CN, normal O, Na, Mg, and Al, and a low ratio of Mg/Mg (∼4%) consistent w...

We have recently calculated (Borges et al. 1995) integrated metallicity indices for single stellar populations (SSP). Effects of age, metallicity and abundances were taken into account. In particular, the explicit dependence of the indicesMg2 and NaD respectively on the ratios [Mg/Fe] and [Na/Fe] was included in the calibration. We report in this work an application of those models to a sample ...

tain low (Mg )i in cytotrophoblast cells. In addition (Mg )i is acutely regulated by (Mg 2 )o. Because placental trophoblasts are sites of maternal–fetal ion exchange, and (Mg )o is altered in preeclampsia, derangements in or modulation of this exchanger may contribute to complications of pregnancy such as pregnancy-induced hypertension, preeclampsia, and preterm labor. If a Na /Mg antiporter i...
