Exposure to chronic mild stress prevents kappa opioid-mediated reinstatement of cocaine and nicotine place preference [PDF]

open access: yes, 2013
Stress increases the risk of drug abuse, causes relapse to drug seeking, and potentiates the rewarding properties of both nicotine and cocaine. Understanding the mechanisms by which stress regulates the rewarding properties of drugs of abuse provides ...

Nitrous Oxide: Mechanism of Its Antinociceptive Action [PDF]

open access: yes, 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.

Rising plasma nociceptin level during development of HCC: A case report [PDF]

open access: yes, 2004
AIM: Although liver cirrhosis is a predisposing factor for hepatocellular carcinoma (HCC), relatively few reports are available on HCC in primary biliary cirrhosis.

Perivascular expression and potent vasoconstrictor effect of dynorphin A in cerebral arteries.

open access: yesPLoS ONE, 2012
BackgroundNumerous literary data indicate that dynorphin A (DYN-A) has a significant impact on cerebral circulation, especially under pathophysiological conditions, but its potential direct influence on the tone of cerebral vessels is obscure. The aim of

Locus coeruleus to basolateral amygdala noradrenergic projections promote anxiety-like behavior [PDF]

open access: yes, 2017
Increased tonic activity of locus coeruleus noradrenergic (LC-NE) neurons induces anxiety-like and aversive behavior. While some information is known about the afferent circuitry that endogenously drives this neural activity and behavior, the downstream ...

Influence of dynorphin A (1-13) and dynorphin A (1-10) amide on stress-induced analgesia.

open access: yesPhysiological research, 1997
Dynorphin A (1-13) and its analog dynorphin A (1-10) amide were applied intracerebroventricularly in male ICR mice. Both dynorphins did not reveal any analgesic activity in tail-flick test under normal (non-stressed) conditions. However, in combination with stress (forced swimming or whole body vibration) both dynorphins prolonged tail-flick latencies ...

Discovery of Amphipathic Dynorphin A Analogues to Inhibit the Neuroexcitatory Effects of Dynorphin A through Bradykinin Receptors in the Spinal Cord

open access: yesJournal of the American Chemical Society, 2014
We hypothesized that under chronic pain conditions, up-regulated dynorphin A (Dyn A) interacts with bradykinin receptors (BRs) in the spinal cord to promote hyperalgesia through an excitatory effect, which is opposite to the well-known inhibitory effect of opioid receptors.

Imaging mass spectrometry reveals elevated nigral levels of dynorphin neuropeptides in L-DOPA-induced dyskinesia in rat model of Parkinson's disease.

open access: yesPLoS ONE, 2011
L-DOPA-induced dyskinesia is a troublesome complication of L-DOPA pharmacotherapy of Parkinson's disease and has been associated with disturbed brain opioid transmission.

Detection and Mapping of Quantitative Trait Loci that Determine Responsiveness [PDF]

open access: yes, 2004
Exposure to 70% N2O evokes a robust antinociceptive effect in C57BL/6 (B6) but not in DBA/2 (D2) inbred mice. This study was conducted to identify quantitative trait loci (QTL) in the mouse genome that might determine responsiveness to N2O.

Prospects for Creation of Cardioprotective and Antiarrhythmic Drugs Based on Opioid Receptor Agonists [PDF]

open access: yes, 2016
It has now been demonstrated that the μ, δ(1), δ(2), and κ(1) opioid receptor (OR) agonists represent the most promising group of opioids for the creation of drugs enhancing cardiac tolerance to the detrimental effects of ischemia/reperfusion (I/R ...
