Current situation on analysis of marine toxins

Reviews in Analytical Chemistry, 2013
Marine toxins are a food safety concern worldwide. This review discusses current analytical methods for those toxins that are legally regulated in Europe, namely domoic acid, saxitoxin, okadaic acid, yessotoxin, pectenotoxin and azaspiracids, and all ...

Mutational analysis of the analgesic peptide DrTx(1-42) revealing a functional role of the amino-terminal turn. [PDF]

PLoS ONE, 2012
BACKGROUND: DrTx(1-42) (a carboxyl-terminally truncated version of drosotoxin) is a potent and selective blocker of tetrodotoxin-resistant (TTX-R) Na(+) channels in rat dorsal root ganglion neurons with analgesic activity. This purpose is to identify key

Marine tetrodotoxin as a risk for human health

Journal of Veterinary Research, 2019
Tetrodotoxin (TTX) is a toxin mainly occurring naturally in contaminated puffer fish, which are a culinary delicacy in Japan. It is also detected in various marine organisms like globefish, starfish, sunfish, stars, frogs, crabs, snails, Australian blue ...

Response Surface Methodology for the Optimization of Ultrasound-Assisted Extraction of Tetrodotoxin from the Liver of Takifugu pseudommus

Toxins, 2018
Tetrodotoxin (TTX) is a marine biotoxin that has high scientific value. However, the lack of efficient TTX extraction and preparation methods has led to a scarcity of TTX samples for clinical application.

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, EarlyView.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

New insights into epileptic spasm generation and treatment from the TTX animal model

Epilepsia Open, EarlyView.
Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

Active groups of saxitoxin and tetrodotoxin as deduced from actions of saxitoxin analogues on frog muscle and squid axon. [PDF]

The Journal of Physiology, 1982
1. The actions of three saxitoxin (STX) analogues have been studied on the frog sartorius muscle fibre and the squid giant axon. One‐‐neosaxitoxin‐‐is a natural analogue, and two‐‐decarbamylsaxitoxin and reduced saxitoxin‐‐are synthetic. 2. The maximum dV/dt of the action potential in paired‐muscle protocol is reduced by the analogues with relative ...

The multiple hit model of infantile and epileptic spasms: The 2025 update

Epilepsia Open, EarlyView.
Abstract Objective Infantile and epileptic spasms syndrome (IESS) is a developmental and epileptic encephalopathy manifesting with epileptic spasms and poor neurodevelopmental outcomes. There is an urgent need for the development of more effective and tolerated therapies.

Mechanistic insights into antibody recognition of tetrodotoxin analogues: Implications for neurotoxicological assessment

Chemico-Biological Interactions
Tetrodotoxins (TTXs) pose significant food safety risks due to their potent neurotoxicity. Growing concerns about the impact of these toxins on public health have driven the development of new detection methods, with immunoassays showing strong potential.
