Sacred offerings and secular foods on Reao Atoll, Tuamotu Archipelago, East Polynesia

open access: yesArchaeology in Oceania, Volume 59, Issue 1, Page 29-67, April 2024.
ABSTRACT In 1976, Yosihiko H. Sinoto conducted extensive archaeological survey and excavations on Reao Atoll, Tuamotu Archipelago as part of a Japanese, multi‐disciplinary expedition led by Prof. Sachiko Hatanaka. Primarily excavating three marae and four habitation sites totalling ∼180 m2, more than 25000 vertebrate remains were recovered.

The development of endo-selective epoxide-opening cascades in water [PDF]

open access: yes, 2009
This tutorial review traces the development of endo-regioselective epoxide-opening reactions in water. Templated, water-promoted epoxide-opening cyclization reactions can offer rapid access to subunits of the ladder polyethers, a fascinating and complex ...

Detection of Extremely Low Level Ciguatoxins through Monitoring of Lithium Adduct Ions by Liquid Chromatography-Triple Quadrupole Tandem Mass Spectrometry

open access: yesToxins
Ciguatera poisoning (CP) is the most common type of marine biotoxin food poisoning worldwide, and it is caused by ciguatoxins (CTXs), thermostable polyether toxins produced by dinoflagellate Gambierdiscus and Fukuyoa spp.

Animal toxins: what features differentiate pore blockers from gate modifiers [PDF]

open access: yes, 2005
A surprisingly large number of animal toxins target voltage sensitive ion channels. Even though there exists toxins for all four major voltage sensitive ion channels, a majority act either on sodium or potassium channels.

Revisiting the Neuroblastoma Cell-Based Assay (CBA-N2a) for the Improved Detection of Marine Toxins Active on Voltage Gated Sodium Channels (VGSCs)

open access: yesToxins, 2020
The neuroblastoma cell-based assay (CBA-N2a) is widely used for the detection of marine biotoxins in seafood products, yet a consensus protocol is still lacking.

Development of New Biosensors to detect Ciguatoxins

open access: yes, 2017
Ciguatoxins are lipid-soluble polyether compounds produced by dinoflagellates from the genus Gambierdiscus spp.. Ciguatoxins are mostly found in tropical and subtropical zones; however, within the last decade, they have been identified in fishes caught in European waters, notably in Madeira (1) and Canary Islands (2), while Gambierdiscus spp. have also

Ladder-Shaped Ion Channel Ligands: Current State of Knowledge

open access: yesMarine Drugs, 2017
Ciguatoxins (CTX) and brevetoxins (BTX) are polycyclic ethereal compounds biosynthesized by the worldwide distributed planktonic and epibenthic dinoflagellates of Gambierdiscus and Karenia genera, correspondingly.

Emerging Marine Biotoxins in Seafood from European Coasts: Incidence and Analytical Challenges

open access: yesFoods, 2019
The presence of emerging contaminants in food and the sources of the contamination are relevant issues in food safety. The impact of climate change on these contaminations is a topic widely debated; however, the consequences of climate change for the ...
