Aluminum sulfate nano structures have been prepared by solution combustion synthesis using aluminum nitrate nonahydrate (Al(NO3)3.9H2O) and ammonium sulfate ((NH4)2SO4). The resultant aluminum sulfate nano structures were calcined at different temperatures to study thermal  decomposition of aluminum sulfate. The crystallinity and phase of  the as-synthesized and calcined samples were char...

caffeine, an adenosine a1, a2a, and a2b receptor antagonist, is frequently used as an adjuvant analgesic in combination with non steroidal anti-inflammatory drugs or opioids. the aim of this study was to evaluate the effects of caffeine on preventing the development of morphine tolerance and analgesia in mice. in this study, different groups of mice received morphine (30 mg/kg) + saline (10 ml/...

background: preterm labor is the leading cause of infant morbidity and mortality so it may be necessary to administer tocolytics for treatment of it. objective: the aim of this study was to compare the efficacy and safety of magnesium sulfate and nifedipine in the management of preterm labor. materials and methods: 100 women with documented preterm labor were randomly assigned to receive magnes...

background: deliberate hypotension is a strategy that reduces intraoperative bleeding and increases the speed of surgery in otolaryngology procedures. magnesium (mg) sulfate is a vasodilator agent that reduces intraoperative hypnotic requirements and in combination with analgesic agents, it reduces intraoperative and postoperative pain. in this study we evaluated the use of intravenous mg sulfa...

Bovine aortic endothelial cells were cultured in medium containing [3H]glucosamine and concentrations of [“S]sulfate ranging from 0.01 to 0.31 mM. While the amount of [‘H]hexosamine incorporated into chondroitin sulfate and heparan sulfate was constant, decreasing concentrations of sulfate resulted in lower [‘“SIsulfate incorporation. Sulfate concentrations greater than 0.1 1 mM were required ...
