Facile and Cost-Effective Detection of Saxitoxin Exploiting Aptamer Structural Switching
Food Technology and Biotechnology, 2015 A simple method to detect saxitoxin (STX), one of the main components of the paralytic shellfish poison from red tide, has been developed. By using a next generation dye for double-stranded DNA we were able to differentiate fluorescence from STX-binding ...

Insertions within the Saxitoxin Biosynthetic Gene Cluster Result in Differential Toxin Profiles
, 2018 The neurotoxin saxitoxin and related paralytic shellfish toxins are produced by multiple species of cyanobacteria and dinoflagellates. This study investigates the two saxitoxin-producing strains of Scytonema crispum, CAWBG524 and CAWBG72, isolated in ...

Ecology and Evolution, Volume 16, Issue 1, January 2026.This study used environmental DNA (eDNA) metabarcoding with 18S rRNA markers to assess microbial diversity in the Lantebung Mangrove Forest, Makassar, Indonesia. It identified 103 microbial species across five kingdoms, revealing higher species richness in open‐water areas (P1) and greater individual abundance under mangrove canopy (P2).

Ecohydrology, Volume 19, Issue 1, January‐February 2026.ABSTRACT The increasing demand for freshwater, in combination with climate change and pollution, compromises the quality and quantity of water resources. These pressures have intensified cyanobacterial blooms, including toxic events that threaten human health and aquatic ecosystems. This study complements the objectives of the Water Framework Directive

The Outer Vestibule of the Na+ Channel–Toxin Receptor and Modulator of Permeation as Well as Gating
Marine Drugs, 2010 The outer vestibule of voltage-gated Na+ channels is formed by extracellular loops connecting the S5 and S6 segments of all four domains (“P-loops”), which fold back into the membrane. Classically, this structure has been implicated in the control of ion
