Efeito da eletro-acupuntura na prevenção da catarata induzida por selenito de sódio em ratos Wistar [PDF]
, 2006 PURPOSE: To investigate whether electroacupuncture can prevent selenite-induced cataract in an experimental model. METHODS: Fifty Wistar rat pups were randomized into 5 groups of 10 animals: Group 1 (control), no procedure was performed; Group 2 ...

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.An independently folded thumb domain from acid‐sensing ion channels (ASICs) preserves ligand‐binding and proton‐sensing properties. NMR‐based interaction and pKa analyses uncover how endogenous and exogenous peptides modulate ASICs, providing a simplified model for rational drug discovery targeting proton‐gated ion channels.

Proteasome targeted therapy in arthritis models -effects on pain and inflammation [PDF]
, 2010 The ubiquitin proteasome system (UPS) regulates numerous cellular functions by selectively degrading cellular proteins. It controls activation of the transcription factor NF-ĸB which is involved in the expression of pro-inflammatory mediators.

Isolation and amino acid sequence analysis of a 4,000-dalton dynorphin from porcine pituitary [PDF]
, 1982 A 4,000-dalton dynorphin was isolated from porcine pituitary. It has 32 amino acids (Mr = 3,986), with the previously described heptadecapeptide (now called dynorphin A) at its amino terminus and a related tridecapeptide, dynorphin B, at its carboxyl ...

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

Pathobiology of dynorphins in trauma and disease [PDF]
Frontiers in Bioscience, 2005 Dynorphins, endogenous opioid neuropeptides derived from the prodynorphin gene, are involved in a variety of normative physiologic functions including antinociception and neuroendocrine signaling, and may be protective to neurons and oligodendroglia via their opioid receptor-mediated effects. However, under experimental or pathophysiological conditions

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)
Phytotherapy Research, EarlyView.ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Nicotine Effects and the Endogenous Opioid System
Journal of Pharmacological Sciences, 2014 .: Nicotine (NIC) is an exogenous ligand of the nicotinic acetylcholine receptor (nAChR), and it influences various functions in the central nervous system. Systemic administration of NIC elicits the release of endogenous opioids (endorphins, enkephalins,
