Molecular effects of Microcystin-LA in tilapia (Oreochromis niloticus)

open access: yesToxicon, 2019
Nile tilapia (Oreochromis niloticus) is a freshwater phytoplanktivorous fish species reported to accumulate and tolerate large amounts of cyanotoxins such as microcystins (MCs). The present study aimed to investigate molecular responses to the acute exposure of Nile tilapia to the Microcystin-LA analogue (MC-LA).

Cyto‐Genotoxic Assessment of Sulfoxaflor in Allium cepa Root Cells and DNA Docking Studies

open access: yesMicroscopy Research and Technique, Volume 88, Issue 5, Page 1521-1533, May 2025.
Cyto‐genotoxic Assessment of Sulfoxaflor in Allium cepa Root Cells and DNA Docking Studies. ABSTRACT Sulfoxaflor (SFX) is an insecticide that is commonly used for the control of sap‐feeding insects. Since SFX is extensively applied globally, it has been implicated in the substantial induction of environmental toxicity.
