“Midbrain periaqueductal gray (PAG) and spinal cord dorsal horn are major action sites of opioid analgesics in the pain pathway. Our previous study has shown that opioid antagonists activate MORS196A-CSTA (a mutant of mu-opioid receptor) as full agonists in vitro cell models and naloxone showed antinociceptive effects after the expression of MORS196A-CSTA in the spinal cord in mice. The purpose of this study is to investigate the site-directed antinociceptive effects of naloxone in mice injected learn more with dsAAV-MORS196A-CSTA-EGFP at spinal cord or at periaqueductal gray. MORS196A-CSTA-EGFP was administered to ICR mice

using dsAAV as vector. We measured MORS196A-CSTA-EGFP expression by detecting the EGFP visualization with a fluorescence microscope. The antinociceptive effect of naloxone was determined by tail-flick test and hot plate test. Drug rewarding effect was evaluated by the conditioned place preference test. Naloxone (10 mg/kg, s.c.) elicited both supraspinal and spinal antinociceptive responses in mice injected with the virus at PAG while only spinal antinociceptive response was observed in mice injected with virus at dorsal horn region. Chronic naloxone treatment

did not induce physical dependence or rewarding effect in mice injected with MORS196A-CSTA-EGFP in spinal cord or PAG. These data suggest that the observed naloxone-induced antinociceptive response is the consequence of the local expression of MORS196A-CSTA at specific Sonidegib mw sites of pain pathway. Injection of such MOR mutant and the systemic administration of naloxone can be a new strategy in the management of chronic pain without the various side effects associated with the use of morphine.

“Objectives: The effects of Okada

Purifying Therapy (OPT), a form of subtle energy (biofield) therapy that originated in Japan, were investigated. Electroencephalograms and the Profile of Mood States scores were measured using a crossover design during OPT and placebo sessions.\n\nParticipants: Nineteen (19) healthy Japanese adults (mean age +/- standard deviation: 40.8 +/- 11.2 years; 10 females) with no previous experience of biofield therapy participated in this study.\n\nMethods: Each session LCL161 mouse lasted 15 minutes. A single-blind, randomized design with a protocol consisting of regular cycles with eyes open followed by eyes closed was used. The power spectral value was calculated in theta (4.0-7.9 Hz), alpha (8.0-12.9 Hz), and beta (13.0-29.9 Hz) frequency ranges.\n\nResults: The power spectral value of the a band at F-p1, F-p2, F-7, F-z, F-8, C-3, C-z, C-4, and P-z increased significantly in the OPT session compared with the placebo session. Mood state was improved after both sessions, and no significant difference was found between the two sessions.
