Advanced Biomaterial Delivery of Hypoxia‐Conditioned Extracellular Vesicles (EVs) as a Therapeutic Platform for Traumatic Brain Injury

Advanced Science, EarlyView.
This research introduces a novel approach to enhance neuroregeneration following Traumatic Brain Injury (TBI). Extracellular Vesicles (EVs) are isolated from human neural progenitor cells under hypoxic conditions, leading to enhanced expression of neurogenic and angiogenic factors.

κ-Opioid Receptor Stimulation Improves Endothelial Function via Akt-stimulated NO Production in Hyperlipidemic Rats

Scientific Reports, 2016
This study was designed to investigate the effect of U50,488H (a selective κ-opioid receptor agonist) on endothelial function impaired by hyperlipidemia and to determine the role of Akt-stimulated NO production in it. Hyperlipidemic model was established

Morphine Tolerance Gated through EZH2‐Mediated Suppression of Trpc5 in Spinal GABAergic Interneurons in Male Mice

Advanced Science, EarlyView.
Chronic morphine suppresses Trpc5 in spinal GABAergic interneurons via EZH2‐mediated histone modification, reducing Ca2+ influx and GABA release. TRPC5 activation enhances morphine analgesia, while EZH2 inhibition restores efficacy and reverses tolerance.

The role of the dynorphin/κ opioid receptor system in anxiety

Acta Pharmacologica Sinica, 2015
Anxiety disorders are the most common and prevalent forms of psychiatric disease, although the biological basis of anxiety is not well understood. The dynorphin/κ opioid receptor system is widely distributed in the central nervous system and has been ...

Efficacy and safety of a selective partial agonist for nociception/orphanin‐FQ peptide (NOP) receptors in patients with insomnia disorder

British Journal of Clinical Pharmacology, EarlyView.
Aims Insomnia is a common sleep disorder, affecting up to 20% of the world population and adversely impacting productivity, health, and overall well‐being. Although pharmacologic options exist to treat insomnia, the health‐related quality of life for patients who are prescribed hypnotics is no higher than for those who are not, revealing a significant ...

Analgesia linked to Nav1.7 loss of function requires µ- and δ-opioid receptors [version 1; referees: 2 approved]

Wellcome Open Research, 2018
Background: Functional deletion of the Scn9a (sodium voltage-gated channel alpha subunit 9) gene encoding sodium channel Nav1.7 makes humans and mice pain-free. Opioid signalling contributes to this analgesic state.

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.
