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 ...

crude glycerol (cg) is an abundantly available and cheap by-product from biodiesel production. value-added applications for cg are highly wanted by industry and several processes such as the use of cg for enhanced oil recovery have been proposed. the aim of this study was to evaluate the sulfide production of sulfate-reducing bacteria (srb) indigenous to oil reservoirs using cg as substrate. th...

background and objective: copper is one of the main micronutrients of body which plays a key role as a cofactor in the function of metabolic enzymes. previous studies have shown that copper sulfate () inhibits long-term potentiation (ltp) in slices of hippocampal ca1 region. whereas ltp is involved in learning and epilepsy, it seems that copper effects on ltp could be associated with its effect...

conclusions this study showed that the addition of intrathecal magnesium sulfate to bupivacaine is not desirable in patients undergoing cesarean section due to the delay in the onset of sensory blockade and the lack of significant effects of magnesium on post-operative pain. results the onset of sensory blockade was delayed in case group compared with control group, and this was statistically s...

conclusions intravenous magnesium sulfate with dose of 15 mg/kg could not prevent laryngospasm and coughing after removal of the endotracheal tube in patients undergoing adenotonsillectomy; however, it reduced coughing and laryngospasm in the magnesium sulfate group compared with the control group. results laryngospasm was not found in the magnesium sulfate group; however, its incidencewas5.7% ...

background new drugs are increasingly used to induce analgesia during surgeries. this study compared the analgesic effects of paracetamol and magnesium sulfate. methods sixty patients with american society of anesthesiologists (asa) class i or ii patients who were candidates for surgery of the lower limbs were randomly divided into three equal groups who were age and gender matched. group 1 rec...

ôbjective: many studies evaluated the efficacy of exercise on some depression indices, but the effect of physical exercise in exhilarating milieu on urine 3-methoxy-4-hydroxyphenylglycol (mhpg) sulfate-the main metabolite of norepinephrine is not clear. the purpose of this research was to study the effect of a six-week intermittent walking in the water on 24-hour urine mhpg sulfate in depressed...
