Alkali and alkaline earth metals hydrogen sulfate catalyzed the one-pot three component condensation reactions of aldehydes, 1,3-dicarbonyl compounds and urea or thiourea under solvent-free conditions leading to 3,4-dihydropyrimidin-2(1H)-ones in high yields at 80 °C. Our results showed that Biginelli reaction not only is pH dependent, but the cation of catalyst plays an importan...

Background and Purpose—Magnesium sulfate is used extensively for prevention of eclamptic seizures. Empirical and clinical evidence supports the effectiveness of magnesium sulfate; however, questions remain as to its safety and mechanism. This review summarizes current evidence supporting the possible mechanisms of action and several controversies for magnesium sulfate treatment. Summary of Revi...

magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. the antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. this study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...

Various electrochemical approaches, including potentiodynamic polarization, open circuit potential evolution and electrochemical impedance spectroscopy (EIS), are employed to investigate the degradation behavior of biomedical magnesium alloy under the influence of aggressive ions, such as chloride, phosphate, carbonate and sulfate, in a physiological environment. The synergetic effects and mutu...

based on a number of studies, magnesium sulfate (mgso4) given after a diffuse axonal injury has gained attention as a useful neuroprotective agent .the present study was conducted to examine if magnesium sulfate has a therapeutic efficacy and safety in patients with a severe diffuse axonal injury. adult patients admitted within 1 hour of a closed traumatic brain injury (tbi) with a severe diffu...

introduction: renal colic can be managed by preventing the contraction movements of ureter muscles. by reducing acetylcholine in the nerve terminals, magnesium sulfate could be effective in this regard. the aim of this study is to investigate the effect of magnesium sulfate on acute renal colic pain relief. method: the present study was a double-blind clinical trial in which the patients suffer...
