    Brain Res Bull 100:61-9. 2014
    ..These results suggest that the development of forced swim-induced thermal hyperalgesia requires the simultaneous presence of increased spinal IL-1β, microglial activation, and relatively decreased serum corticosterone. ..
  2. ncbi request reprint Role of mu-opioid and NMDA receptors in the development and maintenance of repeated swim stress-induced thermal hyperalgesia
    Heberto Suarez-Roca
    Section of Pharmacology, Instituto de Investigaciones Clinicas, Facultad de Medicina, University of Zulia, Apartado Postal 1151, Maracaibo 4001 A, Venezuela
    Behav Brain Res 167:205-11. 2006
    ..Thus, swim stress-induced hyperalgesia might be initiated by the repeated stimulation of mu-opioid and NMDA receptors but maintained only by the activity of NMDA receptors...

    Heberto Suarez-Roca
    Instituto de Investigaciones Clinicas, Section of Neuropharmacology, University of Zulia, Apartado 23, Maracaibo, 4001 A, Venezuela
    Physiol Behav 88:82-7. 2006
    ..Thus, repeated stress produces muscle hyperalgesia that can be pharmacologically dissociated from cutaneous hyperalgesia, suggesting that different mechanisms may underlie these two phenomena...
  4. doi request reprint Reduced GABA neurotransmission underlies hyperalgesia induced by repeated forced swimming stress
    Heberto Suarez-Roca
    Section of Neuropharmacology and Neuroscience, Instituto de Investigaciones Clinicas, Facultad de Medicina, University of Zulia, Apartado Postal 23, Maracaibo 4001 A, Venezuela
    Behav Brain Res 189:159-69. 2008
    ..In conclusion, stress-induced reduction in GABA-A receptor activation is involved in the development of FS stress-induced hyperalgesia...

    Section of Neuropharmacology and Neuroscience, Instituto de Investigaciones Clinicas, Facultad de Medicina, University of Zulia, Maracaibo, Venezuela
    Pain 152:1909-22. 2011
    ..Thus, stress-induced hyperalgesia is initiated by a decreased and delayed GABA release and GABA-A receptor activation, whereas it is maintained by increased glutamate release and NMDA glutamate receptor activation at the spinal level...
  6. ncbi request reprint Repeated swim stress increases pain-induced expression of c-Fos in the rat lumbar cord
    Luis Quintero
    Section of Pharmacology, Institute of Clinical Investigation, School of Medicine, University of Zulia, Apartado Postal 1151, Maracaibo 4001 A, Venezuela
    Brain Res 965:259-68. 2003

    Lorena Pinerua-Shuhaibar
    IVIC Zulia, Maracaibo, Venezuela

    Bercy Uzcátegui
    Natural Products Laboratory, Faculty of Sciences, University of Zulia, Maracaibo, Venezuela
    Invest Clin 45:317-22. 2004
    ..The extract did not exhibit antipyretic activity. Thus, the L. trifolia extract could have therapeutically relevant anti-inflammatory and analgesic properties in humans...
