Modulation of Morphine Analgesia, Antinociceptive Tolerance, and Mu-Opioid Receptor Binding by the Cannabinoid CB2 Receptor Agonist O-1966

open access: yesFrontiers in Pharmacology, 2022
Acutely, non-selective cannabinoid (CB) agonists have been shown to increase morphine antinociceptive effects, and we and others have also demonstrated that non-selective CB agonists attenuate morphine antinociceptive tolerance. Activation of cannabinoid

Suppressing high mobility group box-1 release alleviates morphine tolerance via the adenosine 5’-monophosphate-activated protein kinase/heme oxygenase-1 pathway

open access: yesNeural Regeneration Research, 2023
Opioids, such as morphine, are the most potent drugs used to treat pain. Long-term use results in high tolerance to morphine. High mobility group box-1 (HMGB1) has been shown to participate in neuropathic or inflammatory pain, but its role in morphine ...

Neural mechanisms underlying morphine withdrawal in addicted patients: a review [PDF]

open access: yesReviews in Clinical Medicine, 2015
Morphine is one of the most potent alkaloid in opium, which has substantial medical uses and needs and it is the first active principle purified from herbal source. Morphine has commonly been used for relief of moderate to severe pain as it acts directly

Pharmacokinetic modeling of morphine and its glucuronides: Comparison of nebulization versus intravenous route in healthy volunteers

open access: yesCPT: Pharmacometrics & Systems Pharmacology, 2022
Intravenous (i.v.) morphine is a safe, robust, and recommended treatment for severe pain using the titration principle. Despite its high efficacy, it is impacted by organizational constraints related to venous access.

Endogenous morphine levels are increased in sepsis: a partial implication of neutrophils. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Mammalian cells synthesize morphine and the respective biosynthetic pathway has been elucidated. Human neutrophils release this alkaloid into the media after exposure to morphine precursors.

Linagliptin, a Selective Dipeptidyl Peptidase-4 Inhibitor, Reduces Physical and Behavioral Effects of Morphine Withdrawal

open access: yesMolecules, 2022
(1) Background: Recent data indicate that receptors for GLP-1 peptide are involved in the activity of the mesolimbic system. Thus, the purpose of the present study was to examine the effect of the selective dipeptidyl peptidase-4 (DPP-4) inhibitor ...

Phase Retrieval and Design with Automatic Differentiation [PDF]

open access: yes, 2021
The principal limitation in many areas of astronomy, especially for directly imaging exoplanets, arises from instability in the point spread function (PSF) delivered by the telescope and instrument. To understand the transfer function, it is often necessary to infer a set of optical aberrations given only the intensity distribution on the sensor - the ...

Attenuation by dextromethorphan on the higher liability to morphine-induced reward, caused by prenatal exposure of morphine in rat offspring

open access: yesJournal of Biomedical Science, 2009
Co-administration of dextromethorphan (DM) with morphine during pregnancy and throughout lactation has been found to reduce morphine physical dependence and tolerance in rat offspring.

Oral morphine induces spinal 5‐hydroxytryptamine (5‐HT) release using an opioid receptor‐independent mechanism

open access: yesPharmacology Research & Perspectives, 2023
Morphine induces spinal 5‐hydroxytryptamine (5‐HT) release, but the role and mechanism of the spinal 5‐HT release induced by morphine are not well understood.
