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.

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.

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 ...

Field monitoring of copepodamides using a new application for solid phase adsorption toxin tracking

Limnology and Oceanography: Methods, Volume 22, Issue 12, Page 877-888, December 2024.
Abstract Chemical signaling is ubiquitous in the marine environment. Plankton rely on chemical signals to find mates, hunt prey, and respond to threats, and these small‐scale interactions can propagate into community‐wide cascades and large‐scale ecological changes. The chemical signaling exchange in the open ocean is poorly understood, and fundamental

Assessing methods for detecting Alexandrium catenella (Dinophyceae) and paralytic shellfish toxins in Southeast Alaska

Integrated Environmental Assessment and Management, Volume 20, Issue 6, Page 2189-2202, November 2024.
Abstract Blooms of Alexandrium catenella threaten to disrupt subsistence, recreational, and commercial shellfish harvest in Alaska, as the paralytic shellfish toxins (PSTs) produced pose a serious public health risk and can lead to costly shutdowns for shellfish farmers.

From Pregnancy to Pathogens: Boosting Lateral Flow Assays Sensitivity with a Hydrogel Reaction Trap

Advanced Materials Interfaces, Volume 11, Issue 27, September 23, 2024.
Hydrogel‐coated lateral flow assays (LFAs) are a promising solution to improve the detection performance of rapid diagnostic systems. Poly(ethylene glycol) diacrylate (PEGDA) hydrogel as a “reaction trap” ensures optimized reaction times by regulating the flow, leading to better sensitivity detection across various applications.

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.

Synthetic Approaches to Zetekitoxin AB, a Potent Voltage-Gated Sodium Channel Inhibitor

Marine Drugs, 2019
Voltage-gated sodium channels (NaVs) are membrane proteins that are involved in the generation and propagation of action potentials in neurons. Recently, the structure of a complex made of a tetrodotoxin-sensitive (TTX-s) NaV subtype with saxitoxin (STX),
