Phylogenomic analysis reveals extensive phylogenetic mosaicism in the Human GPCR Superfamily [PDF]

, 2007
A novel high throughput phylogenomic analysis (HTP) was applied to the rhodopsin G-protein coupled receptor (GPCR) family. Instances of phylogenetic mosaicism between receptors were found to be frequent, often as instances of correlated mosaicism and ...

Contribution of Addictovigilance data to assess adverse‐events linked to psychoactive substances in children and adolescents

British Journal of Clinical Pharmacology, EarlyView.
Aims We sought to characterize adverse events and deaths associated with the use of psychoactive substances in children and adolescents. Methods Two French Addictovigilance databases were analysed: spontaneous reports and deaths over the period 2016–2021, in subjects aged 10–<18 years. An unsupervised classification was implemented on consumption data (

Butorphanol: Effects of a Prototypical Agonist-Antagonist Analgesic on κ-Opioid Receptors

Journal of Pharmacological Sciences, 2005
The opioid analgesic, butorphanol (17-cyclobutylmethyl-3,14-dihydroxymorphinan) tartrate is a prototypical agonist-antagonist opioid analgesic agent whose potential for abuse has been the cause of litigation in the United States.

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.

Impact of diclofenac risk minimization measures addressing cardiovascular risk on analgesic use in musculoskeletal disorders

British Journal of Clinical Pharmacology, EarlyView.
Aims In 2013, risk minimization measures (RMMs) were introduced in Europe to address the increased cardiovascular risk linked to diclofenac. This study aimed to assess the impact of those RMMs on analgesic use. Methods Primary care data from CPRD GOLD (UK) were used.

The integration of the British Pharmacological Society's prescription safety assessment into the WHO 6‐step model of rational pharmacotherapy in a Turkish medical school

British Journal of Clinical Pharmacology, EarlyView.
Aims At Koç University School of Medicine, a one‐week rational pharmacotherapy (RPHM) programme, modelled after WHO 6‐step, has been introduced in the fourth‐year curriculum to improve prescription skills. For efficient problem‐based learning (PBL) sessions on a prespecified topic, students need to brush up on basic pharmacology knowledge, so we ...

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 ...

Nitrous Oxide: Mechanism of Its Antinociceptive Action [PDF]

, 1995
Nitrous oxide (N2O) is an anesthetic gas known to produce an analgesic effect at sub-anesthetic concentrations. This analgesic property of N2O can be clinically exploited in a broad range of conditions where pain relief is indicated.

Opioid receptor-triggered spinal mTORC1 activation contributes to morphine tolerance and hyperalgesia.

Journal of Clinical Investigation, 2014
The development of opioid-induced analgesic tolerance and hyperalgesia is a clinical challenge for managing chronic pain. Adaptive changes in protein translation in the nervous system are thought to promote opioid tolerance and hyperalgesia; however, how
