Marine Toxins


Presentation

  • The present study explores this neurobehavioral finding, using diffusion tensor magnetic resonance imaging and spectroscopy.[biorxiv.org]
  • The present study explores the basis of this neurobehavioral finding with in vivo imaging techniques, including diffusion tensor magnetic resonance imaging and spectroscopy.[ncbi.nlm.nih.gov]
  • Japanese and international experts assert that the discovery proves military defoliants were present in Okinawa.[japantimes.co.jp]
  • Since present trends in nutrient loading are assumed to have skewed some historically stable situations towards higher N: P ratios, the stimulation of toxin production by P-limiting media has important ecological consequences; in niches where DIN: DIP[archimer.ifremer.fr]
  • The curcial steps in the present synthesis involve the ring expansion of tetrahydropyran to oxepane, 6- endo cyclization of epoxy alcohol, and insertion of a C-4 unit to the A-ring.[journal.csj.jp]
Fishing
  • Marine biotoxins are naturally occurring chemicals, caused by certain types of toxic algae that accumulate in fish and shellfish.[who.int]
  • Ciguatoxin is produced by algae that form the diet of many fish in the Pacific and Indian Oceans, and causes so-called ciguatera poisoning in people who eat those fish.[chemistryworld.com]
  • Some cases of poisoning by consumption of contaminated fish, like the Ciguatera poisoning, occur unexpectedly and they are not easy to detect previously since the fish that carry the toxin do not have appearance and/or symptoms of illness.[scielo.sa.cr]
  • Puffer fish make saxitoxin - earlier this year 13 people in Florida were poisoned when they ate locally caught puffer fish.[nature.com]
  • Occurrence of the toxic phytoflagellate Prymnesium parvum and associated fish mortality in a Norwegian fjord system. Can. J. Fish. Aquat Sci. 48: 2316-2323. [details] additional source Moestrup Ø. 1994.[marinespecies.org]
Falling
  • Blooms of the toxic algae along the California coast typically occur in the spring and fall and last just a few weeks.[sciencedaily.com]
  • In the fall of 1991, another natural neurotoxin called domoic acid was discovered in the California marine environment in several species, including shellfish.[cdph.ca.gov]
Weakness
  • A thousand times more potent than the nerve gas sarin, it can stifle breathing and cause numbness, dizziness, weakness, nausea and occasionally death. CIA agents in the 1950s were rumoured to carry saxitoxin suicide capsules.[nature.com]
  • In 2015, weak upwelling provided periodic injections of nutrients, but every time the upwelling got started the warm blob pushed back onto the coast.[sciencedaily.com]
Physician
  • Austrian Academy of Physicians 1 credit, 1:00 hour BMJ Learning modules have been certified for DFT Punkte.[learning.bmj.com]
Food Poisoning
  • Abstract A Coryneform bacterium, isolated from the digestive gland of the Japanese ivory shell, Babylonia japonica, was shown to produce neosurugatoxin and prosurugatoxin, the causative toxins of a food poisoning outbreak in 1965 following ingestion of[jstage.jst.go.jp]
  • Now that Moray eels need no longer fear the blender, the team hope that strategies to control ciguatera food poisoning should follow soon. Bea Perks[chemistryworld.com]
Nausea
  • A thousand times more potent than the nerve gas sarin, it can stifle breathing and cause numbness, dizziness, weakness, nausea and occasionally death. CIA agents in the 1950s were rumoured to carry saxitoxin suicide capsules.[nature.com]

Treatment

  • Figure 2 Effect of treatment with increasing concentrations of TTX on [Ca 2 ] i in CGCs exposed to 100 nM ATX. Buffer or TTX was added to neurons 3 min before the addition of ATX.[pnas.org]

Prevention

  • Because PSP and domoic acid toxicity represents a serious ongoing public health threat that requires year-round attention, the CDPH has implemented a prevention program that has traditionally been comprised of six basic elements: (1) a coastal phytoplankton[cdph.ca.gov]
  • This neurotoxic response can be prevented by coapplication of the sodium channel antagonist TTX or by NMDA receptor antagonists ( 10 ).[pnas.org]
  • -Japan Status of Forces Agreement, which prevents Japanese officials from conducting environmental tests on U.S. military bases and relieves the Pentagon of all responsibility to clean up Japanese land formerly under its control.[japantimes.co.jp]
