Development of certified reference materials for diarrhetic shellfish poisoning toxins, part 2: shellfish matrix materials

, 2016
Okadaic acid (OA) and its analogs, dinophysistoxins-1 (DTX1) and -2 (DTX2) are lipophilic biotoxins produced by marine algae that can accumulate in shellfish and cause the human illness known as diarrhetic shellfish poisoning (DSP). Regulatory testing of

Harmful Microalgae Exhibit Broad Environmental Adaptability in High‐Salinity Area Across the Dafengjiang River Estuary

Ecology and Evolution, Volume 14, Issue 10, October 2024.
The alpha diversity and beta diversity of the harmful microalgae community exhibited significant variations in salinity and seasonality (p < 0.05). A wider range of environmental thresholds in high‐salinity samples than those in other samples of the harmful microalgae community.

Toxins of Okadaic Acid-Group Increase Malignant Properties in Cells of Colon Cancer

Toxins, 2020
Diarrhetic shellfish poisoning (DSP) is a syndrome caused by the intake of shellfish contaminated with a group of lipophilic and thermostable toxins, which consists of okadaic acid (OA), dinophysistoxin-1 (DTX-1) and dinophysistoxin-2 (DTX-2).

RNA-Seq Analysis for Assessing the Early Response to DSP Toxins in Mytilus galloprovincialis Digestive Gland and Gill

Toxins, 2018
The harmful effects of diarrhetic shellfish poisoning (DSP) toxins on mammalian cell lines have been widely assessed. Studies in bivalves suggest that mussels display a resistance to the cytogenotoxic effects of DSP toxins.

Seasonal Early Warning of Impacts of Harmful Algal Blooms on Farmed Shellfish in Coastal Waters of Scotland

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract Harmful Algal Blooms (HABs) can produce phycotoxins that accumulate in shellfish and subsequently poison aquatic predators and human consumers, potentially causing significant economic impacts to the shellfish aquaculture industry. HAB events are challenging to foresee as they are driven by complex inter‐annual and seasonal changes in physical,

The CHROMEVALOA Database: A Resource for the Evaluation of Okadaic Acid Contamination in the Marine Environment Based on the Chromatin-Associated Transcriptome of the Mussel Mytilus galloprovincialis

Marine Drugs, 2013
Okadaic Acid (OA) constitutes the main active principle in Diarrhetic Shellfish Poisoning (DSP) toxins produced during Harmful Algal Blooms (HABs), representing a serious threat for human consumers of edible shellfish.

Importance of integrating mixoplankton into marine ecosystem policy and management—Examples from the Marine Strategy Framework Directive

Integrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1366-1383, September 2024.
Abstract Marine plankton capable of photosynthesis and predation (“mixoplankton”) comprise up to 50% of protist plankton and include many harmful species. However, marine environmental management policies, including the European Union Marine Strategy Framework Directive (MSFD) and the USEPA, assume a strict dichotomy between autotrophic phytoplankton ...

Okadaic Acid Meet and Greet: An Insight into Detection Methods, Response Strategies and Genotoxic Effects in Marine Invertebrates

Marine Drugs, 2013
Harmful Algal Blooms (HABs) constitute one of the most important sources of contamination in the oceans, producing high concentrations of potentially harmful biotoxins that are accumulated across the food chains.

Global warming and coastal protected areas: A study on phytoplankton abundance and sea surface temperature in different regions of the Brazilian South Atlantic Coastal Ocean

Ecology and Evolution, Volume 14, Issue 8, August 2024.
The Baleia Franca Environmental Protection Area spans 3872 km2, featuring extensive preserved coastal and marine zones in Brazil's South Atlantic. Preliminary satellite data indicate that this region might have experienced a slightly lower rate of sea surface temperature (SST) change over recent decades compared to neighboring states.

SEASONAL AND SPATIAL PATTERNS OF TOXIGENIC SPECIES OF Dinophysis AND Pseudo-nitzschia IN A SUBTROPICAL BRAZILIAN ESTUARY

Brazilian Journal of Oceanography, 2015
This study investigated the spatial and temporal distributions of toxigenic phytoplankton species between October 2010 and April 2012 in Guaratuba Bay, Paraná state, Brazil, where aquaculture has been intensified in recent years.
