Sulfate contamination has been identified as a serious environmental issue in the Everglades ecosystem. However, it has received less attention compared to P enrichment. Sulfate enters the Arthur R. Marshall Loxahatchee National Wildlife Refuge (Refuge), a remnant of the historic Everglades, in pumped stormwater discharges with a mean concentration of approximately 50 mg L(-1), and marsh interi...

MgSeO4·7H2O is isostructural with the analogous sulfate, MgSO4·7H2O, consisting of isolated [Mg(H2O)6](2+) octa-hedra and [SeO4](2-) tetra-hedra, linked by O-H⋯O hydrogen bonds, with a single inter-stitial lattice water mol-ecule. As in the sulfate, the [Mg(H2O)6](2+) coordination octa-hedron is elongated along one axis due to the tetra-hedral coordination of the two apical water mol-ecules; th...

the present study is a designed protocol for investigation of the analgesic effect of oral and intraperitoneal (i.p.) administration of alcoholic datura stramonium (ds) seed extract as a rich source of alkaloid substances. male nmri rats were divided into control and treatment groups. the treatment rats received different doses of the ds seed extract, which was prepared from alcoholic smashed s...

Overview: Stability experiments indicate that amorphous sulfate phases may be important constituents of martian surface materials [1-2]; there is also considerable spectral evidence for non-crystalline sulfate phases on Europa [3-4]. However, the thermal infrared (TIR) and near-infrared (NIR) spectral characteristics of these phases are largely unknown. X-ray amorphous Mg-and Fe-sulfate phases ...

As an N-methyl-D-aspartate antagonist, magnesium sulfate has analgesic properties and reduces noxious input during surgery. The aim of the study was to determine the effect of preemptive intravenous low-dose magnesium sulfate on early postoperative pain after laparoscopic cholecystectomy. In this prospective, randomized study, 60 ASA I-II patients undergoing elective laparoscopic cholecystectom...

Water is an essential nutrient for feedlot cattle. Drinking water may contain a variety of compounds. The important question is to what degree these substances impact water palatability and cattle health. The NRC in 1974 published limits for some potential problem causing substances in drinking water. Recommended safe upper limits for nitrate, sulfate, and total dissolved solids (TDS) were 440,...

background there have been many concerns about alteration in hemodynamic parameters within and shortly after endotracheal intubation (eti) in patients scheduled for elective coronary artery bypass grafting (cabg). objectives we compared the attenuation effect of magnesium sulfate and lidocaine on hemodynamic responses after eti, in patients undergoing cabg. patients and methods in this randomiz...

OBJECTIVE A thick endothelial glycocalyx provides the endothelial surface with a nonadherent shield. Oxidized LDL (Ox-LDL) degrades the endothelial glycocalyx. We hypothesized that glycocalyx degradation stimulates leukocyte-endothelial cell adhesion, whereas intravascular supplementation with sulfated polysaccharides reconstitutes the endothelial glycocalyx and attenuates Ox-LDL-induced leukoc...

BACKGROUND Intracellular magnesium ([Mg]i) plays an important role in the regulation of myocardial metabolism, contractility, and the maintenance of transsarcolemmal and intracellular ionic gradients. An understanding of the role of magnesium in the clinical setting, however, is hampered by the lack of an assay of intracellular tissue magnesium levels. METHODS AND RESULTS We used energy-dispe...
