TLDR
It is concluded that the enhancement of ichthyotoxicity of EPA in the presence of superoxide can account for the high C. marina fish killing potential.About:

Journal ArticleDOI
Antibacterial free fatty acids: activities, mechanisms of action and biotechnological potential
Andrew P. Desbois,Valerie Smith +1 more
TL;DR: Their broad spectrum of activity, non-specific mode of action and safety makes them attractive as antibacterial agents for various applications in medicine, agriculture and food preservation, especially where the use of conventional antibiotics is undesirable or prohibited.
Journal ArticleDOI
Progress in understanding harmful algal blooms: paradigm shifts and new technologies for research, monitoring, and management.
TL;DR: Here, HAB science is reviewed with an eye toward new concepts and approaches, emphasizing, where possible, the unexpected yet promising new directions that research has taken in this diverse field.
Journal ArticleDOI
Superoxide production by marine microalgae : I. Survey of 37 species from 6 classes
TL;DR: It is speculated that superoxide, while not the sole ichthyotoxic principle, may play a wider role in algal toxicity than previously considered, and a broad classification of microalgae based upon superoxide production is proposed.
Journal ArticleDOI
Life cycle, physiology, ecology and red tide occurrences of the fish-killing raphidophyte Chattonella
Ichiro Imai,Mineo Yamaguchi +1 more
TL;DR: As a mechanism of red tide occurrences of Chattonella in coastal sea, “diatom resting hypothesis” was presented and biological control using diatoms is proposed through the germination/rejuvenation of resting stages suspending from bottom sediments to euphotic layer by sediment perturbation with submarine tractors or fishing trawling gears.
Journal ArticleDOI
Hydroclimatic conditions trigger record harmful algal bloom in western Patagonia (summer 2016)
TL;DR: Using time series of atmospheric, hydrologic and oceanographic data, it is shown that an increase in surface water temperature and reduced freshwater input resulted in a weakening of the vertical stratification in the fjords and sounds of this region, ultimately resulting in an active harmful algal bloom in coastal southern Chile.

Brevetoxins : unique activators of voltage-sensitive sodium channels
TL;DR: Competition experiments using natural toxin probes specific for sites 1-4 of the voltage-dependent sodium channel have illustrated that PbTx-3 does not bind to any of the previously described sites associated with the channel.
Journal Article
Brevetoxins, unique activators of voltage-sensitive sodium channels, bind to specific sites in rat brain synaptosomes.
TL;DR: In this article, the polyether lipid-soluble toxins isolated from the marine dinoflagellate Ptychodiscus brevis (formerly Gymnodinium breve) have been determined to bind to a unique site associated with rat brain synaptosomes.

TL;DR: It is revealed that the relatively small chemical differences between CTx-1, CTX-2 andCTX-3 give rise to significant structure-activity and pharmacokinetic differences that are comparable to mouse lethality.
