In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...

nanomagnetic mgfe2o4 is an active, stable, and reusable catalyst for the oxidation of alcohols. the oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. the reactions were carried out in the presence of water as solvent and oxone (at room temperature) or h2o2 (at 60 ºc) as an oxidant. the catalyst was investigated...

endotrachial intubation can have serious deleterious hemodynamic changes. hypertension and tachycardia are especially dangerous in coronary artery disease, intracranial hypertension. magnesium sulfate is known for its vasodilating properties. several studies have reported favorable protective hemodynamic properties of magnesium when used as a premedicant in cardiac or elderly patients. our aim ...

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)....

Introduction: Themaintenance of hemodynamic stability in brain aneurysm surgery has paramount clinical significance in order to prevent vasospasm in the patients with aneurysmal subarachnoid hemorrhage. Regarding this, the present study was conducted to assess the role of magnesium sulfate in preventing vasospasm and maintaining hemodynamic stability during endovascular coiling procedure for br...

Severe acute asthma is a medical emergency that must be quickly diagnosed and treated. Initial treatment includes a bronchodilator agent and systemic corticosteroids. In severe cases with poor response to the standard treatment, intravenous magnesium sulfate is a therapeutic option. This article aimed a literature review on the use of intravenous magnesium sulfate in the emergency room treatmen...

In the crystal structure of the title salt, 3C(5)H(6)NO(+)·HSO(4) (-)·SO(4) (2-)·H(2)O, the hydrogen sulfate ion is linked to the sulfate ion by an O-H⋯O hydrogen bond. The hydrogen sulfate-sulfate anion is a hydrogen-bond acceptor for the three independent cations and the uncoordinated water mol-ecule, the hydrogen-bonding inter-actions giving rise to a three-dimensional hydrogen-bonded networ...

BACKGROUND Surgeon satisfaction and patient analgesia during the procedure of laparoscopic surgery are important issues. The aim of this work was to study if an intrathecal (IT) Bupivacaine combined with Magnesium sulfate may or may not provide good surgeon satisfaction in addition to improvement of intraoperative and postoperative analgesia. METHODS Sixty female patients were enrolled in thi...

Our previous report has shown that the shapes of calcium oxalate crystals formed in a supersaturated solution with glycosaminoglycan varied with glycosaminoglycan species. The present study was conducted to demonstrate the effect of magnesium on the shapes of calcium oxalate crystals with glycosaminoglycan by optical and scanning electron microscopy. In the presence of magnesium, the phenomenon...

Background: Previous studies have shown that magnesium sulfate (MgSO4) administered in a patient with a diffuse axonal injury (DAI) can serve as a useful neuroprotective agent. The present study was conducted to examine whether magnesium sulfate has a therapeutic efficacy and safety in patients with a severe diffuse axonal injury. Methods: Adult patients admitted within 1 hour of a closed Traum...
