Changes in Liver Metabolome Induced by Pterostilbene and Resveratrol in a Rat Model of Liver Steatosis

open access: yesMolecular Nutrition &Food Research, Volume 69, Issue 15, August 2025.
Resveratrol and pterostilbene reduced the steatotic status of animals fed a high‐fat, high‐sucrose diet, involving differential and specific mechanisms of action for each stilbene. Thus, changes in riboflavin metabolism, nicotinamide mononucleotide metabolism, or in the LysoPC(18:1)‐mediated effects contribute to the specific actions of pterostilbene ...

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes [PDF]

open access: yes, 2017
Venom systems have evolved on multiple occasions across the animal kingdom, and they can act as key adaptations to protect animals from predators. Consequently, venomous animals serve as models for a rich source of mimicry types, as non-venomous ...

Opioid receptors in cardiovascular function

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 16, Page 3710-3725, August 2025.
Opioid receptors are G protein‐coupled receptors expressed by various cells in the heart, including myocytes and nerve fibres, and play a crucial role in modulating cardiac function. These receptors influence neural transmission, heart rate and myocyte contractility, offering cardioprotection.

A novel non-Opioid binding site for endomorphin-1 [PDF]

open access: yes, 2016
Endomorphins are natural amidated opioid tetrapeptides with the following structure: Tyr-Pro-Trp-Phe-NH2 (endomorphin-1),and Tyr-Pro-Phe-Phe-NH2 (endomorphin-2).

The role of the endogenous opioid system in modulating orthodontic‐induced neurogenic inflammation of the dental pulp: A comprehensive review of the literature

open access: yesInternational Endodontic Journal, Volume 58, Issue 8, Page 1126-1145, August 2025.
Abstract Background Orthodontic forces may lead to neurogenic inflammation in the dental pulp by triggering the release of somatosensory neuropeptides such as Substance P (SP), Calcitonin gene‐related peptide (CGRP) and Neurokinin A (NKA). In the vast majority of patients, acute symptoms are not triggered, probably due to the control of the neurogenic ...

Hyperpolarization Modulation of the T‐Type hCav3.2 Channel by Human Synenkephalin [1–53], a Shrew Neurotoxin Analogue without Paralytic Effects

open access: yesAngewandte Chemie, Volume 137, Issue 27, July 1, 2025.
Human synenkephalin [1–53] (hSYN), an analogue peptide of shrew saliva neurotoxins, was synthesized and its structural characteristics studied. Synthetic hSYN potently activated the T‐type voltage‐gated Ca channel hCav3.2 but did not paralyze mealworms. These findings offer new insight into neurological disorder treatment and evolutionary mechanisms of

High resolution NMR study of T1 magnetic relaxation dispersion. IV. Proton relaxation in amino acids and Met-enkephalin pentapeptide [PDF]

open access: yes, 2014
Nuclear Magnetic Relaxation Dispersion (NMRD) of protons was studied in the pentapeptide Met-enkephalin and the amino acids, which constitute it. Experiments were run by using high-resolution Nuclear Magnetic Resonance (NMR) in combination with fast ...

Molecular Aspect of Annelid Neuroendocrine system

open access: yes, 2007
Hormonal processes along with enzymatic processing similar to that found in vertebrates occur in annelids. Amino acid sequence determination of annelids precursor gene products reveals the presence of the respective peptides that exhibit high sequence ...

Adoptive transfer of M2 macrophages reduces neuropathic pain via opioid peptides [PDF]

open access: yes, 2016
Background During the inflammation which occurs following nerve damage, macrophages are recruited to the site of injury. Phenotypic diversity is a hallmark of the macrophage lineage and includes pro-inflammatory M1 and anti- inflammatory M2 populations ...
