“I never realized how hard recovery is.” A quasi‐experimental evaluation of a youth participatory action research project for opioid prevention

American Journal of Community Psychology, EarlyView.
Abstract Youth participatory action research (YPAR) has been effectively used for substance use prevention. Yet, YPAR has not been evaluated for opioids, which negatively impact individuals and communities across the United States. The current study evaluated an opioid‐focused YPAR project.

Deletion of arrestin-3 does not reduce drug-seeking behavior in a longitudinal paradigm of oral morphine self-administration

Frontiers in Pharmacology
IntroductionOpioid drugs are potent analgesics that mimic the endogenous opioid peptides, endorphins and enkephalins, by activating the µ-opioid receptor.

Endogenous opioids regulate moment-to-moment neuronal communication and excitability

Nature Communications, 2017
The endogenous opioid system regulates fear and anxiety, but the underlying cellular mechanism is unclear. Winterset al. shows that in the intercalated cells (ITC) of the amygdala, endogenous opioids suppress glutamatergic inputs via the δ-opioid ...

Efficacy of Local Bupivacaine Injection of Postoperative Pain in Endoscopic Sinus Surgery

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Regional anesthesia is effective in alleviating postoperative pain and reducing the requirement for systemic pain medications. However, optimal postoperative pain management in endoscopic sinus surgery (ESS) remains challenging.

Chronic opioid pretreatment potentiates the sensitization of fear learning by trauma. [PDF]

, 2020
Despite the large comorbidity between PTSD and opioid use disorders, as well as the common treatment of physical injuries resulting from trauma with opioids, the ability of opioid treatments to subsequently modify PTSD-related behavior has not been well ...

Can variability in the effect of opioids on refractory breathlessness be explained by genetic factors? [PDF]

, 2015
© 2015, BMJ Publishing Group. All rights reserved. Objectives: Opioids modulate the perception of breathlessness with a considerable variation in response, with poor correlation between the required opioid dose and symptom severity. The objective of this

Photoswitchable Peptides as Molecular Tools to Encode Structural Order and Disorder in Intracellular Assemblies

Angewandte Chemie International Edition, EarlyView.
We present a photoswitchable peptide conjugate which exhibits isomerism‐dependent self‐assembly: the planar trans‐isomer assembles into well‐ordered nanofibers while the non‐planar cis‐isomer yields disordered aggregates. Our study offers a direct visualization on the effects of structure formation inside living cells.

Influence of the hypothalamic arcuate nucleus on intraocular pressure and the role of opioid peptides.

PLoS ONE, 2014
BackgroundAn opioid peptide neuron/humoral feedback regulation might be involved in changes of intraocular pressure (IOP). The aims of this study are to investigate the effects of arcuate nucleus (ARC) and opioid peptides on intraocular pressure (IOP ...

A mu–delta opioid receptor brain atlas reveals neuronal co-occurrence in subcortical networks

Brain Structure and Function, 2014
Opioid receptors are G protein-coupled receptors (GPCRs) that modulate brain function at all levels of neural integration, including autonomic, sensory, emotional and cognitive processing.
