it has been shown that stress and chronic pain could prevent the development of tolerance to morphine analgesia, which appears to be related to the activation of hypothalamus–pitutitary–adrenal (hpa) axis, activation of neuroendocrine systems and changes in neurochemical levels. moreover, the involvement of nitric oxide (no) in the development of tolerance to morphine analgesia has been implica...
Expression of tolC and organic solvent tolerance of Escherichia coli ciprofloxacin resistant mutants
AcrAB-TolC is a major efflux pump in Escherichia coli. It was reported that tolC is overexpressed and involves in improving the organic solvent tolerance level in Escherichia coli marR mutants that are resistant to several antibiotics, such as ciprofloxacin. Low and intermediate levels resistance did not improve organic solvent tolerance. Thus, in this descriptive-experimental study it was deci...
