  • Morphine is the most efficacious and widely prescribed treatment for pain. However, it decreases the total amount of deep sleep and rapid eye movement sleep in humans. Acute morphine administration at low doses causes wakefulness in animal models. To clarify the mechanism by which morphine affects s

  • It is well documented that the Toll-like receptor 4 (TLR4)/NF-κB signaling mediates early inflammation during myocardial ischemia and reperfusion. Our previous study has demonstrated that κ-opioid receptor stimulation with U50,488H produces cardioprotective and anti-inflammatory effects. The aim o

  • BACKGROUND: Opioids may cause progressive enhancement of pain sensitivity (opioid-induced hyperalgesia [OIH]) and thus, exacerbate existing pain. Animal studies also demonstrate paradoxical OIH with an ultralow dose (ULD, subanalgesic) of opioid; eg, the μ-opioid, morphine. Repeated administration
