introduction:nitrate entrance to water bodies can cause eutrophication and decrease quality of them, furthermore it can effect on human health so concentration of nitrate must be at defined standard level. there are several methods for reduction or removal of nitrate in water such as ion exchange, reverse osmosis, electrodialysis and denitrification. microbial denitrification of nitrate in anox...

conclusions magnesium at low dose decreases sore throat and pain severity more effectively compared to ketamine gargle. results there were no significant differences between age, sex, and body mass index (bmi) between two groups of patients. hemodynamics of patients, including blood pressure, respiratory rate, oxygen saturation %, and conscious state were not significantly different (p > 0.05)....

BACKGROUND Pre-eclampsia/eclampsia is one of the most common causes of maternal and perinatal morbidity and mortality in low and middle income countries. Magnesium sulfate is the drug of choice for prevention of seizures as part of comprehensive management of the disease. Despite the compelling evidence for the effectiveness of magnesium sulfate, concern has been expressed about its safety and ...

BACKGROUND AND PURPOSE Pilot clinical trials using magnesium sulfate in patients with acute aneurysmal subarachnoid hemorrhage have reported trends toward improvement in clinical outcomes. This Phase III study aimed to compare intravenous magnesium sulfate infusion with saline placebo among such patients. METHODS We recruited patients with aneurysmal subarachnoid hemorrhage within 48 hours of...

The objective of our study is to quantitatively examine the available evidence regarding the efficacy and side effects of magnesium sulfate for acute tocolysis (from randomized trials) compared with placebo and beta-agonist agents. Randomized trials comparing magnesium sulfate with placebo or beta-agonists for tocolysis were identified with a MEDLINE-based search and was supplemented by a searc...

In the US, the routine use of magnesium sulfate for seizure prophylaxis in women with preeclampsia is an ingrained obstetric practice. During the past decade, several observational studies and randomized trials have described the use of various regimens of magnesium sulfate to prevent or reduce the rate of seizures and complications in women with preeclampsia. There are only 2 double-blind, pla...
