Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]

open access: yes, 2004
Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

Multi-Overlap Simulations for Transitions between Reference Configurations

open access: yes, 2003
We introduce a new procedure to construct weight factors, which flatten the probability density of the overlap with respect to some pre-defined reference configuration.

Inhibition of activity of GABA transporter GAT1 by δ-opioid receptor [PDF]

open access: yes, 2012
Analgesia is a well-documented effect of acupuncture. A critical role in pain sensation plays the nervous system, including the GABAergic system and opioid receptor (OR) activation.

Piper auritum (Kunth) Fungal Endophytes: A Source of Metabolites to Inhibit the Formation of Advanced Glycation End Products

open access: yesChemistry &Biodiversity, Volume 22, Issue 10, October 2025.
Endophytic fungi of P. auritum were evaluated for their ability to produce inhibitors of formation of advanced glycation end products (AGEs). Neopestalotiopsis sp. H2 and Diaporthe sp. H5 extracts were the most active. So, we performed their chemical profiling by untargeted and phenolics‐targeted metabolomic approaches to identify the potential ...

Replica-Exchange Simulated Tempering Method for Simulations of Frustrated Systems

open access: yes, 2000
We propose a new method for the determination of the weight factor for the simulated tempering method. In this method a short replica-exchange simulation is performed and the simulated tempering weight factor is obtained by the multiple-histogram ...

Immunohistochemical Profile of a Conspicuously Organized Structure in the Dorsal Forebrain of the Peacock Gudgeon, Tateurndina ocellicauda

open access: yesJournal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In the dorsal telencephalon of gobiiform fishes, there is a conspicuously organized structure, consisting of readily identifiable subregions that are surrounded by layers of cell bodies. Using immunohistochemistry against several antigen targets in this structure, we demonstrate that each of these subregions is characterized by its own individual ...

On the G-protein-coupled receptor heteromers and their allosteric receptor-receptor interactions in the central nervous system: focus on their role in pain modulation [PDF]

open access: yes, 2013
The modulatory role of allosteric receptor-receptor interactions in the pain pathways of the Central Nervous System and the peripheral nociceptors has become of increasing interest.

Consolidation, Systematic Appraisal and Comparison of Guideline Recommendations Regarding Management of Chronic Pain: Protocol for a Digital Chronic Pain Recommendation Map

open access: yesClinical and Public Health Guidelines, Volume 2, Issue 4, October 2025.
ABSTRACT Introduction Chronic pain affects 1 in 5 adults and children globally; however, management remains highly variable and low value care is common. Inconsistent recommendations among clinical practice guidelines for management of chronic pain contribute to suboptimal patient management.

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

open access: yesFrontiers in Molecular Neuroscience, 2017
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.
