Molecular detection of a potentially toxic diatom species [PDF]

, 2015
A few diatom species produce toxins that affect human and animal health. Among these, members of the Pseudo-nitzschia genus were the first diatoms unambiguously identified as producer of domoic acid, a neurotoxin affecting molluscan shell-fish, birds ...

Current situation on analysis of marine toxins

Reviews in Analytical Chemistry, 2013
Marine toxins are a food safety concern worldwide. This review discusses current analytical methods for those toxins that are legally regulated in Europe, namely domoic acid, saxitoxin, okadaic acid, yessotoxin, pectenotoxin and azaspiracids, and all ...

An Autonomous Platform for Near Real-Time Surveillance of Harmful Algae and Their Toxins in Dynamic Coastal Shelf Environments

Journal of Marine Science and Engineering, 2021
Efforts to identify in situ the mechanisms underpinning the response of harmful algae to climate change demand frequent observations in dynamic and often difficult to access marine and freshwater environments.

Using SeaWiFS and In Situ Data for HAB Prediction in the Northern Gulf of Mexico: Decision Tree Analysis [PDF]

, 2009
To date, 13 potential HAB species have been detected in coastal waters of Mississippi and Alabama, including representatives of the diatom genera Pseudo-nitzschia and Chaetoceros, and dinoflagellate genera Karenia, Gonyaulax, Akashiwo, Karlodinium, and ...

Monitoring the presence of domoic acid in the production areas of bivalve molluscs

Italian Journal of Food Safety, 2016
Algal biotoxins, chemical compounds produced by some microscopic algae, constitute the phytoplankton. The mussels, feeding on phytoplankton, can accumulate these compounds to become themselves toxic.

Co-occurrence of marine and freshwater phycotoxins in oysters, and analysis of possible predictors for management

Toxicon: X, 2023
Oysters (Crassostrea virginica) were screened for 12 phycotoxins over two years in nearshore waters to collect baseline phycotoxin data and to determine prevalence of phycotoxin co-occurrence in the commercially and ecologically-relevant species.

β-N-methylamino-L-alanine Enhances Neurotoxicity Through Multiple Mechanisms [PDF]

, 2007
The idea that the environmental toxin β-N-methylamino-l-alanine (BMAA) is involved in neurodegenerative diseases on Guam has risen and fallen over the years.

The neuroprotective effects of virally-derived caspase inhibitors p35 and crmA following a necrotic insult

Neurobiology of Disease, 2003
Neuronal excitotoxicity causes energetic impairment and the ensuing cell death has historically been regarded as necrotic. Recent findings, however, indicate that apoptosis may participate in excitotoxicity.

Phytoplankton Dynamics in the Middle Adriatic Estuary, with a Focus on the Potentially Toxic Genus Pseudo-nitzschia

Journal of Marine Science and Engineering, 2020
The Krka River estuary is a karstic, permanently stratified estuary due to the strong freshwater inflow. It is a special environment in which to study the phytoplankton community, especially because this area is an important aquaculture site. Among other

Fear of grazing rivals the toxin‐inducing effects of nutrients in two marine harmful algae – a meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...
