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...
