Stereoselective Synthesis of Spiroacetal Domain Derivatives of the Plant Glycoside Ranuncoside and of Okadaic Acid and Dinophysistoxins-1 and 2 From Marine Algae

open access: yesNatural Product Communications, 2020
Spiroacetals constitute the central structural core element of numerous natural products and are mostly represented as bicyclic or tricyclic domains. Typical natural products with tricyclic spiroacetals are (+)-ranuncoside 1 , a glycoside isolated from ...

The Mechanism of Diarrhetic Shellfish Poisoning Toxin Production in Prorocentrum spp.: Physiological and Molecular Perspectives

open access: yesToxins, 2016
Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disorder caused by the consumption of seafood contaminated with okadaic acid (OA) and dinophysistoxins (DTXs).

Study of Adsorption and Flocculation Properties of Natural Clays to Remove Prorocentrum lima

open access: yesToxins, 2015
High accumulations of phytoplankton species that produce toxins are referred to as harmful algal blooms (HABs). HABs represent one of the most important sources of contamination in marine environments, as well as a serious threat to public health ...

Current Trends and Challenges for Rapid SMART Diagnostics at Point-of-Site Testing for Marine Toxins

open access: yesSensors, 2021
In the past twenty years marine biotoxin analysis in routine regulatory monitoring has advanced significantly in Europe (EU) and other regions from the use of the mouse bioassay (MBA) towards the high-end analytical techniques such as high-performance ...

Grazer‐induced bioluminescence and toxicity in marine dinoflagellates

open access: yesLimnology and Oceanography, Volume 70, Issue 12, Page 3769-3783, December 2025.
Abstract Marine copepods are the most abundant multicellular zooplankton in the global oceans. They imprint their surrounding waters with a unique bouquet of chemical compounds, including polar lipids such as copepodamides. Prey organisms can detect copepodamides and respond by inducing defensive traits including bioluminescence, toxin production ...

Oceanography and Pacific Oyster Biochemical Composition in a Novel Oyster‐Growing Region

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 5, October 2025.
ABSTRACT The farming of Pacific oysters (Crassostrea [Magallana] gigas) is a rapidly growing industry in Alaska, where farms represent some of the highest latitude oyster cultivation efforts in the world. Little is known about the nearshore oceanography where Alaskan farms are located, or how the subarctic marine context influences oyster tissue ...

Risks for public health related to the presence of tetrodotoxin (TTX) and TTX analogues in marine bivalves and gastropods

open access: yesEFSA Journal, Volume 15, Issue 4, April 2017., 2017
Abstract Tetrodotoxin (TTX) and its analogues are produced by marine bacteria and have been detected in marine bivalves and gastropods from European waters. The European Commission asked EFSA for a scientific opinion on the risks to public health related to the presence of TTX and TTX analogues in marine bivalves and gastropods.

A generic approach for the development of short-term predictions of Escherichia coli and biotoxins in shellfish

open access: yesAquaculture Environment Interactions, 2018
Microbiological contamination or elevated marine biotoxin concentrations within shellfish can result in temporary closure of shellfish aquaculture harvesting, leading to financial loss for the aquaculture business and a potential reduction in consumer ...
