PSP affects those who come into contact with the affected shellfish by ingestion. [1] The toxins responsible for most shellfish poisonings—mainly saxitoxin, although several other toxins have been found, such as neosaxitoxin and gonyautoxins I to IV—are water-insoluble, and heat- and acid-stable. Therefore, ordinary cooking methods will not ...
Saxitoxin is a neurotoxin naturally produced by certain species of marine dinoflagellates (Alexandrium sp., Gymnodinium sp., Pyrodinium sp.) and freshwater cyanobacteria (Dolichospermum cicinale sp., some Aphanizomenon spp., Cylindrospermopsis sp., Lyngbya sp., Planktothrix sp.) [1] [2] Saxitoxin accumulates in "planktivorous invertebrates, including mollusks (bivalves and gastropods ...
Amnesic shellfish poisoning (ASP) is an illness caused by consumption of shellfish that contain the marine biotoxin called domoic acid. [1] In mammals, including humans, domoic acid acts as a neurotoxin, causing permanent short-term memory loss, brain damage, and death in severe cases.
A central failing: The housing department does not have a system to ensure that landlords are removing lead hazards before families with children move into an apartment. If they see chipping paint, tenants can notify their landlord directly or submit a complaint to the city’s 311 system, a public number that lets people report non-emergency ...

Hallmark symptoms of ciguatera in humans include gastrointestinal, cardiovascular, and neurological effects. [5] [6] Gastrointestinal symptoms include nausea, vomiting, and diarrhea, usually followed by neurological symptoms such as headaches, muscle aches, paresthesia, numbness of extremities, mouth and lips, reversal of hot and cold sensation, [7] [8] ataxia, vertigo, and hallucinations.
It was a launch title for the PSP. A Java ME version for mobile phones was released by Glu Mobile in 2008 titled Metal Gear Acid Mobile. [3] Acid focuses on turn-based tactics, using a trading card-based system to control the main character's movements and actions. Acid in the name stands for "Active Command Intelligence Duel". The cards are ...
Junction damage manifesting as reverse-bias leakage increases to the point of shorting. Metallisation and polysilicon burnout, where damage is limited to metal and polysilicon interconnects, thin film resistors and diffused resistors. Charge injection, where hot carriers generated by avalanche breakdown are injected into the oxide layer.
