Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Effects of chlorpyrifos on histopathological biomarkers of the freshwater teleost Oreochromis niloticus

Fisheries & Aquatic Life, 2023
An attempt was made to evaluate histopathological changes in the gills, liver, and kidney tissues of the freshwater teleost Oreochromis niloticus as biomarkers of chlorpyrifos toxicity. An experiment was conducted in glass aquaria with O.

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

Environmental Toxicology, EarlyView.
ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Electrochemical aptasensors for ultrasensitive multiplexed detection: Towards a new era of precision diagnostics and environmental monitoring

VIEW, EarlyView.
Electrochemical aptasensors are emerging as powerful platforms for precision diagnostics and environmental monitoring, owing to their high selectivity, programmability and compatibility with miniaturised systems. However, their broader application is constrained by limited signal intensity and challenges in reliable multiplexed detection.
