Changes of Adenylate Cyclase and Guanylate Cyclase in the Frontal Cortex, Lenticula, Corpus Amygdaloideum, and Hippocampus in Morphine-dependent Rats

open access: yesJournal of Forensic Science and Medicine, 2016
To detect the changes of adenylate cyclase (AC) and guanylate cyclase (GC) in the four cerebral regions that are concerned with psychogenic dependence of morphine in rats, including the frontal cortex, lenticula, corpus amygdaloideum, and hippocampus. To

Carveol mitigates the development of the morphine anti-nociceptive tolerance, physical dependence, and conditioned place preference in mice

open access: yesHeliyon
Emergence of analgesic tolerance and dependence to morphine is frequently the limiting factor in the use of this agent in the management of pain. Hence, this study aimed to investigate the beneficial effects of the natural compound carveol (CV) against ...

Nociceptin attenuates the escalation of oxycodone self-administration by normalizing CeA-GABA transmission in highly addicted rats. [PDF]

open access: yes, 2020
Approximately 25% of patients who are prescribed opioids for chronic pain misuse them, and 5 to 10% develop an opioid use disorder. Although the neurobiological target of opioids is well known, the molecular mechanisms that are responsible for the ...

Pathological regional blood flow in opiate-dependent patients during withdrawal: A HMPAO-SPECT study [PDF]

open access: yes, 1998
The aims of the present study were to investigate regional cerebral blood flow (rCBF) in heroin-dependent patients during withdrawal and to assess the relation between these changes and duration of heroin consumption and withdrawal data.

An opioid-like system regulating feeding behavior in C. elegans [PDF]

open access: yes, 2015
Neuropeptides are essential for the regulation of appetite. Here we show that neuropeptides could regulate feeding in mutants that lack neurotransmission from the motor neurons that stimulate feeding muscles. We identified nlp-24 by an RNAi screen of 115

Inhibition of alpha7 nicotinic receptors in the ventral hippocampus selectively attenuates reinstatement of morphine‐conditioned place preference and associated changes in AMPA receptor binding [PDF]

open access: yes, 2018
Recurrent relapse is a major problem in treating opiate addiction. Pavlovian conditioning plays a role in recurrent relapse whereby exposure to cues learned during drug intake can precipitate relapse to drug taking.
