Toxicity of microcystins in the isolated hepatocytes of common carp (Cyprinus carpio L.) [PDF]

, 2007
The toxicity of hepatotoxic microcystins produced mainly by Microcystis aeruginosa in mammals and fishes was well studied in recent years. However, there were scarcely reports in toxic effects of microcystins on isolated hepatocytes of fishes, especially

Dominance and toxicity without lethality: Exploring biomass, cyanometabolites, and Daphnia responses across Cyanobacterial strains

Journal of Phycology, EarlyView.
Abstract Cyanobacteria are cosmopolitan, important components of biomass with a remarkable ability to synthesize a diverse array of bioactive compounds, some of which may have toxic effects on other organisms and ecosystems. In this study, filamentous cyanobacterial strains isolated predominantly from temperate European freshwaters (Aphanizomenon ...

Irrigation-dependent accumulation of microcystin in different crops under mid-scale greenhouse conditions

Journal of Agriculture and Food Research
The potential health risks of consuming crops irrigated with microcystin-contaminated water are increasingly recognized. While previous studies demonstrated microcystin accumulation in crops, they do not fully reflect real-world conditions and have data ...

Multimodal Cross‐Attentive Graph‐Based Framework for Predicting In Vivo Endocrine Disruptors

Advanced Science, Volume 13, Issue 21, 13 April 2026.
A multimodal cross‐attentive graph neural network integrates molecular graphs with androgen and estrogen adverse outcome pathway (AOP)–anchored in vitro assay signals to predict in vivo endocrine disruption. By fusing information on Tier‐1 AOP logits with chemical structures, the framework achieves high accuracy and provides assay‐traceable ...

Occurrence and Diversity of Cyanotoxins and Retinoid Compounds in Antarctic Microbial Mats: Evidence From James Ross Island

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Occurrence and distribution of cyanotoxins and retinoids across different Antarctic ecosystems at James Ross Island. These ecosystems harbour diverse microbial communities dominated by autotrophic cyanobacteria and algae, which can produce hazardous compounds for animals.

Drinking Water Quality Regulations: A Contrast Between Germany and Latin America

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT This article investigates the differences among drinking water quality standards adopted in Latin American countries, Mexico, Cuba, and the European Union, considering the growing challenge of ensuring safe drinking water in a context marked by environmental pressures, climate change, and the occurrence of emerging contaminants. The study aims

Estimating Operational Costs of Activated Carbon for Water Treatment Plants by Predicting the Rise of Harmful Algal Blooms Under Climate Change in Korea Using Machine Learning

Water Environment Research, Volume 98, Issue 3, March 2026.
This study investigated future operational costs in water treatment (WT) plants. Random forest modeling projected 3–5 times more abundant cyanobacteria by 2100 due to climate change. Increased microcystins demanded substantially more activated carbon and, as a result, WT costs could rise to $6–22/household/month.

Transcriptional alteration of cytoskeletal genes induced by microcystins in three organs of rats [PDF]

, 2010
This study explored the mechanisms of toxicity of microcystins by measuring the transcription levels of nine cytoskeletal genes (actin, tubulin, vimentin, ezrin, radixin, moesin, MAP1b, tau, stathmin) in the liver, kidney and spleen of male Wistar rats ...

Photocatalytic degradation of microcystin-LR in aqueous solutions

Chemosphere, 2013
In this work, the photocatalytic degradation of aqueous microcystin-LR was studied using TiO(2) and ZnO as photocatalysts. The process was optimised and characterised at the bench scale (200 mL); both semiconductors exhibited a high degradation capacity at reaction times of 1 min (degradation greater than 95%).

Teleosts as Models for Epigenetic Inheritance

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Teleost fish exhibit a striking divergence from mammals in how they regulate their epigenome. Unlike mammals, they do not undergo the extensive DNA methylation erasure and resetting events that occur during early embryogenesis, germline specification, and spermatogenesis.
