Newest firstComorbid substance use disorders (SUDs) are common but difficult to study due to the complex, interacting and overlapping mechanisms through which they affect brain networks. Many datasets collected to investigate a specific SUD include participants with comorbid SUDs. Although most studies treat comorbid SUDs as covariates of no interest, these covariates also contain untapped information. This is particularly re…
Open article record in new tab ↗ObjectiveIn this study, we evaluated the concordance between urine drug screening (UDS) and self-reported use in a pragmatic randomized clinical trial.MethodsOur data was drawn from OPTIMA, a 24-week pragmatic multicentric open-label randomized-controlled trial comparing flexible take-home dosing of buprenorphine/naloxone to the methadone standard model of care for treating prescription-type opioid use disorder. A…
Rationale/objectives Targeting cannabinoid receptor type 1 (CB1R) has shown promise for treating opioid withdrawal symptoms. This study aimed to investigate the efficacy of a specific CB1R negative allosteric modulator (NAM), Org27569, in reducing both naloxone-precipitated and protracted withdrawal symptoms in oxycodone-dependent mice. Methods Mice received escalating doses of oxycodone (9-33 mg/kg IP) or saline…
Open article record in new tab ↗The TRPM8 channel, a temperature-sensitive ion channel, plays a crucial role in various physiological processes, particularly in the modulation of inflammation and nociception. Although electroacupuncture (EA) is a recognized analgesic treatment for pain conditions, its interaction with TRPM8 remains underexplored. This study aims to determine TRPM8's role in EA-induced analgesia using a murine model of inflammato…
Pain is susceptible to various cognitive factors. Suppression of pain by hunger is well known, but the effect of food intake after fasting (i.e. refeeding) on pain remains unknown. In the present study, we examined whether inflammatory pain behavior is affected by 24 h fasting and 2 h refeeding. In formalin-induced acute inflammatory pain model, fasting suppressed pain behavior only in the second phase and the ana…
Open article record in new tab ↗The present study examined the potential antinociceptive activity of C18 5-HT (βN-octadecanoyl-5-hydroxytryptamide) using chemical and thermal nociception models in mice. Orally administered C18 5-HT (0.1, 1 and 10 mg/kg) produced significant dose-dependent antinociceptive effects in formalin-, capsaicin- and glutamate-induced licking models. This compound also induced a significant increase in the response to the…
Open article record in new tab ↗PnTx4(6-1), henceforth renamed δ-Ctenitoxin-Pn1a (δ-CNTX-Pn1a), a peptide from Phoneutria nigriventer spider venom, initially described as an insect toxin, binds to site 3 of sodium channels in nerve cord synaptosomes and slows down sodium current inactivation in isolated axons in cockroaches (Periplaneta americana). δ-CNTX-Pn1a does not cause any apparent toxicity to mice, when intracerebroventricularly injected…
