Environmental and Biological Factors of Relevance to Shellfish Production in Northern Ireland: Insights From 20 Years of Regional Monitoring Data

Reviews in Aquaculture, Volume 17, Issue 1, January 2025.
ABSTRACT A historical analysis was conducted to evaluate monitoring data in the coastal and estuarine waters of Northern Ireland over the 20‐year period between 2001 and 2022 to identify current and emerging concerns and gaps in analysis relative to the sustainability of the aquaculture industry.

Effects of saxitoxin (STX) and veratridine on bacterial Na+ -K+ fluxes: a prokaryote-based STX bioassay

, 2003
Saxitoxin (STX) is a potent natural sodium channel blocker and represents a significant health concern worldwide. We describe here the antagonistic effects of STX and veratridine (VTD), an Na+ channel activator, on three gram-negative bacteria and their ...

Developmental toxicity of one marine dinoflagellate toxicant-saxitoxin

, 2013
Saxitoxin (STX), found mainly in marine dinoflagellates, is one water-soluble neurotoxin. When some fishes accumulate STX and are consumed by humans, it would cause a series of diseases, especially to children.

Safety of oil from Schizochytrium limacinum (strain ATCC‐20889) for use in infant and follow‐on formula as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of an oil derived from the microalga Schizochytrium sp. (strain ATCC‐20889) as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

Influence of biochar on the removal of Microcystin-LR and Saxitoxin from aqueous solutions

Scientific Reports
The present study assessed the effective use of biochar for the adsorption of two potent HAB toxins namely, Microcystin-LR (MCLR) and Saxitoxin (STX) through a combination of dosage, kinetic, equilibrium, initial pH, and competitive adsorption ...

Enhanced SERS aptasensor for sensitive detection of saxitoxin based on HAuCl4/H2O2 reaction system and Pt/Au nanozyme

Food Science and Human Wellness
Saxitoxin (STX) is a marine biotoxin produced by cyanobacteria and methanobacteria, which is harmful to humans and aquatic organisms. Therefore, it is urgent to establish an efficient, sensitive and selective method for the screening of STX.

The effect of the cyanobacterial toxin saxitoxin on neurodevelopment [PDF]

, 2017
The potent neurotoxin saxitoxin (STX) belongs to a group of structurally related analogues, collectively known as the paralytic shellfish toxins, produced by both marine and freshwater phytoplankton. This group of toxins act by blocking the voltage-gated

Structural characterization of the saxitoxin-targeting APTSTX1 aptamer using optical tweezers and molecular dynamics simulations.

PLoS ONE, 2019
Optical tweezers have enabled the exploration of picoNewton forces and dynamics in single-molecule systems such as DNA and molecular motors. In this work, we used optical tweezers to study the folding/unfolding dynamics of the APTSTX1-aptamer, a single ...
