Does this proposed regulation conform to the relevant international standard? This enrichment was consistent with two biosynthetic pathways. Inseabirds attacked the Capitola area in Californiaand though it was never confirmed, they were thought to be domokco the influence of domoic acid. In addition there is a synergistic effect with endogenous glutamate and N-Methyl-D-aspartate receptor agonists that contribute to the excitotoxicity.
China If applicable, name of acldo government involved: Retrieved 15 April Because the hippocampus may be severely damaged, short-term memory loss occurs. The Marine Mammal Center.
Journal of Environmental Biology. If so, identify the standard: Domolco no, describe, whenever possible, how and why it deviates from the international standard: Ionotropic glutamate receptor modulators.
Consequently, poisonings have been affecting sea animals, birds, and humans. Retrieved 2 April Northwest fisheries science center.
In order to be diagnosed and treated if poisoned, domoic acid must first be detected. This standard applies to the determination of amnesic shellfish poisoning, domoic acid, in the meat, columnae, pallium and products thereof not including salted products of sea bivalves. Access a collection of Canadian resources on all aspects of English and French, including quizzes.
This page was last edited on 15 Octoberat Domoic acid producing algal blooms are associated with the phenomenon of amnesic shellfish poisoning ASP. In December , more than Canadians fell ill acid two died after East Coast mussels became contaminated from domoic acid. In marine mammals, domoic acid typically causes seizures and tremors. In which subject field?
Proposed date of entry into force: In the brain, domoic acid especially damages the hippocampus and amygdaloid nucleus. Domoic acid has a domoici strong affinity for these receptors, which results in excitotoxicity initiated by an integrative action on ionotropic glutamate receptors at both sides of the synapse, coupled with the effect of blocking the channel from rapid desensitization.
Retrieved from ” https: It can accumulate in high concentrations in the tissues of these plankton feeders when the toxic phytoplankton are high in concentration in the surrounding waters. Inusing 13 C – and 14 C -labelled precursors, the biosynthesis of domoic acid in the diatom genus Pseudo-nitzschia was examined. The kidney is affected at a hundred times lower than the concentration allowed under FDA regulations.
Retrieved 17 April Blue mussels Mytulis edulis contaminated with domoic acid were blamed.
The effects of domoic acid have been attributed to several mechanisms, but the one of concern is through glutamate receptors. Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes.
Ministry of Health MOH. The language you choose must correspond to the language of the term you have entered. Domoic acid is a structural analog of kainic acidprolineand endogenous excitatory neurotransmitter glutamate.
Dangerous levels of domoic acid have been calculated based on cases such as the one on Prince Edward island.
