Recent Advances in Aptasensing Strategies for Monitoring Phycotoxins: Promising for Food Safety

open access: yesBiosensors, 2022
Phycotoxins or marine toxins cause massive harm to humans, livestock, and pets. Current strategies based on ordinary methods are long time-wise and require expert operators, and are not reliable for on-site and real-time use.

Marine toxins and the cytoskeleton [PDF]

open access: yesThe FEBS Journal, 2008
One of the most striking features of marine toxins is that many of them produce diarrhea. This effect has been attributed to an effect on the cytoskeleton, with the consequent disorganization of the adherent cells on the intestinal cell barrier leading to an excess of liquid.

Alzheimer’s Disease and Toxins Produced by Marine Dinoflagellates: An Issue to Explore

open access: yesMarine Drugs, 2022
This paper examined the toxins naturally produced by marine dinoflagellates and their effects on increases in β-amyloid plaques along with tau protein hyperphosphorylation, both major drivers of Alzheimer’s disease (AD). This approach is in line with the

Five Years Monitoring the Emergence of Unregulated Toxins in Shellfish in France (EMERGTOX 2018–2022)

open access: yesMarine Drugs, 2023
Shellfish accumulate microalgal toxins, which can make them unsafe for human consumption. In France, in accordance with EU regulations, three groups of marine toxins are currently under official monitoring: lipophilic toxins, saxitoxins, and domoic acid.

Paralytic shellfish toxins in the Atlantic horse mackerel (Trachurus trachurus) over a bloom of Gymnodinium catenatum: the prevalence of decarbamoylsaxitoxin in the marine food web

open access: yesScientia Marina, 2013
This study reports the accumulation of paralytic shellfish toxins (PSTs) in Atlantic horse mackerel (Trachurus trachurus) over a bloom of the toxigenic dinoflagellate Gymnodinium catenatum. High levels of toxins, up to 4800 μg STXeq kg–1, were registered

Illnesses Caused by Marine Toxins [PDF]

open access: yesClinical Infectious Diseases, 2005
Marine toxins are produced by algae or bacteria and are concentrated in contaminated seafood. Substantial increases in seafood consumption in recent years, together with globalization of the seafood trade, have increased potential exposure to these agents. Marine toxins produce neurological, gastrointestinal, and cardiovascular syndromes, some of which

Health and Environmental Impacts of Cyanobacteria and Cyanotoxins from Freshwater to Seawater

open access: yesToxins
Cyanobacterial harmful algal blooms (cyanoHABs) are a natural phenomenon produced mainly by the interaction between natural and anthropogenic events. CyanoHABs are characterized by the production of cyanotoxins that can have harmful effects on different ...
