Article Synopsis
  • Saxitoxin (STX) is a neurotoxic cyanotoxin that induces oxidative stress and metabolic changes, prompting a study on the protective effects of açaí fruit (Euterpe oleracea) against its toxicity in shrimp (Litopenaeus vannamei).
  • Shrimps were fed a diet supplemented with lyophilized açaí for 30 days before being exposed to STX; molecular docking indicated that STX variants can interact with a specific enzyme (mu isoform of GST) crucial for detoxification.
  • Results showed that while açaí supplementation reduced some toxic effects (like malondialdehyde levels in shrimp hepatopancreas), it also had

This study evaluated the effect of dietary inclusion of lyophilized açaí Euterpe oleracea (LEO) on redox status of shrimp Litopenaeus vannamei (initial weight 1.5 ± 0.39 g) upon exposure to cyanotoxin nodularin (NOD) in bioflocs system.

Saxitoxins (STXs) are potent neurotoxins that block voltage-gated channels in neurons and induce cytotoxicity. These toxins not only can generate reactive oxygen species but also can alter antioxidant levels, promoting oxidative stress. Under this pro-oxidant situation, the use of the antioxidant lipoic acid (LA) can represent a chemoprotective alternative to minimize the deleterious effects induced by neurotoxins as STXs.

Saxitoxins (STXs) are potent neurotoxins that also induce cytotoxicity through the generation of reactive oxygen species. Carbon nanotubes (CNTs) are nanomaterials that can promote a Trojan horse effect, facilitating the entry of toxic molecules to cells when adsorbed to nanomaterials. The interaction of pristine single-walled (SW)CNTs and carboxylated (SWCNT-COOH) nanotubes with STX was evaluated by ab initio simulation and bioassays using the cell line HT-22.
