Effects of kappa-opioid agonist U-50488 and p38 MAPK inhibitor SB203580 on the spike activity of pyramidal neurons in the basolateral amygdala [PDF]
Research Results in Pharmacology 10(1): 1-6 (2024)Introduction: Kappa-opioid receptor (KOR) signaling in the basolateral amygdala (BLA) underlies KOR agonist-induced aversion. In this study, we aimed to understand the individual and combined effects of KOR agonist U-50488 and p38 MAPK inhibitor SB203580 on the spiking activity of pyramidal neurons in the BLA to shed light on the complex interplay ...

Straub tail, the deprivation effect and addiction to aggression [PDF]
arXiv, 2006 It has been observed that male mice who are consistently winning fights with conspecifics can raise their tail, which is very similar to a morphine-induced Straub tail response. Since this response is a typical index of opiate activation, it has been proposed that the opioidergic systems of such mice are chronically activated.

Towards Better Opioid Antagonists Using Deep Reinforcement Learning [PDF]
arXiv, 2020 Naloxone, an opioid antagonist, has been widely used to save lives from opioid overdose, a leading cause for death in the opioid epidemic. However, naloxone has short brain retention ability, which limits its therapeutic efficacy. Developing better opioid antagonists is critical in combating the opioid epidemic.Instead of exhaustively searching in a ...

Frontiers in Pediatrics, 2018 The endogenous opioid system, comprised of multiple opioid neuropeptide and receptor gene families, is highly expressed by developing neural cells and can significantly influence neuronal and glial maturation. In many central nervous system (CNS) regions,

Identifying Risk of Opioid Use Disorder for Patients Taking Opioid Medications with Deep Learning [PDF]
arXiv, 2020 The United States is experiencing an opioid epidemic, and there were more than 10 million opioid misusers aged 12 or older each year. Identifying patients at high risk of Opioid Use Disorder (OUD) can help to make early clinical interventions to reduce the risk of OUD.

BJA Open, 2023 Opioids are a mainstay in acute pain management and produce their effects and side effects (e.g., tolerance, opioid-use disorder and immune suppression) by interaction with opioid receptors.
