Stress-evoked opioid release inhibits pain in major depressive disorder [PDF]

open access: yes, 2008
To determine whether stress-evoked release of endogenous opioids might account for hypoalgesia in major depressive disorder (MDD), the μ-opioid antagonist naltrexone (50 mg) or placebo was administered double-blind to 24 participants with MDD and to 31 ...

Place‐based risk: Examining relationships between adolescent perceptions of community risk factors and adolescent substance use across geographic contexts

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Mixed evidence for the influence of structural and social factors on adolescent substance use behaviors exists across the rural–urban continuum. Therefore, this study explores how adolescent perceptions of structural and social community risk factors are associated with lifetime and past 30‐day use of alcohol, marijuana, cigarettes, and ...

Peripheral Opioid Receptors

open access: yesAnnals of Medicine, 1995
Recent experimental and clinical research has demonstrated that opioids can produce potent and receptor-specific analgesic effects outside the central nervous system. Opioid receptors are localized on peripheral terminals of sensory nerves and their endogenous ligands, opioid peptides, have been discovered in immune cells within inflamed tissue.

Trends in Opioid‐Related Poisonings and Mental and Behavioral Disorders From 2006 to 2022 Among a Large Cohort of Injured Workers in Ontario, Canada

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Work‐related injuries may increase risk for opioid‐related harms. Yet there remains a gap in our understanding of trends in opioid‐related harms over time among injured workers. We estimated trends in hospital encounters for opioid‐related harms among injured workers in Ontario, Canada from 2006 to 2022.

The EXPLAIN Study: Exploring Arthrogryposis Multiplex Congenita in Adults in Norway — A Description of Demographic, Medical, and Neurological Findings

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Arthrogryposis Multiplex Congenita (AMC) encompasses several hundred conditions with diverse genetic, pathophysiological, and clinical origins. The overarching EXPLAIN study explores underlying causes and implications of AMC and represents the largest clinical cohort of adults with AMC reported to date.

Benzodiazepine receptors and the control of ingestive behaviour in the rat [PDF]

open access: yes, 1996
When administered systemically, benzodiazepine receptor agonists have been shown to increase food intake in a number of species. Conversely, benzodiazepine receptor inverse agonists bring about reliable decreases in feeding.

Adipose‐derived mesenchymal stem cell injection into the KI10 acupoint mitigates cartilage damage in KOA rats through PGE2‐mediated α7nAChR/NF‐κB pathway

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In our research, KOA rat models were established and treated with ADSC injection into the KI10 acupoint. Pain relief, behavioral function, and joint structural improvements were systematically assessed using ethological tests, imaging, histopathological staining, transmission electron microscopy, and molecular analyses.

Neurotransmitter‐Defined Degeneration Patterns in Sporadic and C9orf72‐Associated Amyotrophic Lateral Sclerosis: Predilection to GABAergic, Serotonergic, Opioid, Glutamatergic, Endocannabinoid, and Microglial Systems—Implications for Therapy Development

open access: yesAnnals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a markedly distinctive clinical and neuroradiological signature, with the preferential involvement of specific brain networks and the apparent sparing of others. The molecular underpinnings of the strikingly selective anatomical vulnerability have not been fully elucidated to date despite the potential ...

Therapeutic Prospects of Ketamine for Cataplexy in Narcolepsy Type 1: Evidence from a Human Case and a Murine Model

open access: yesAnnals of Neurology, EarlyView.
Narcolepsy type 1 is characterized by cataplexy, for which current treatments targeting monoaminergic, histaminergic, and GABAergic pathways may be ineffective or poorly tolerated. We report the case of a 34‐year‐old man with narcolepsy type 1, intolerant to standard therapies, who experienced marked and sustained cataplexy reduction with morning ...

The effect of subcutaneous naloxone on experimentally induced pain [PDF]

open access: yes, 2008
The heat pain threshold was assessed in 32 healthy participants after a mild burn on the dorsal surface of each hand, after injection of an opioid antagonist (80 μg naloxone) or vehicle alone (0.2 mL saline) into the burnt skin of 1 hand, and after ...
