One Health and Cyanobacteria in Freshwater Systems: Animal Illnesses and Deaths Are Sentinel Events for Human Health Risks

open access: yesToxins, 2015
Harmful cyanobacterial blooms have adversely impacted human and animal health for thousands of years. Recently, the health impacts of harmful cyanobacteria blooms are becoming more frequently detected and reported.

Impact of Microcystin-LR on Liver Function Varies by Dose and Sex in Mice

open access: yesToxins, 2018
Microcystin (MC) exposure is an increasing concern because more geographical locations are covered with cyanobacterial blooms as eutrophication and bloom-favoring environmental factors become more prevalent worldwide. Acute MC exposure has been linked to

Characterization and Diversity of Microcystins Produced by Cyanobacteria from the Curonian Lagoon (SE Baltic Sea)

open access: yesToxins, 2021
Microcystins (MCs) are the most widely distributed and structurally diverse cyanotoxins that can have significant health impacts on living organisms, including humans.

Structure and Effects of Cyanobacterial Lipopolysaccharides

open access: yesMarine Drugs, 2015
Lipopolysaccharide (LPS) is a component of the outer membrane of mainly Gram-negative bacteria and cyanobacteria. The LPS molecules from marine and terrestrial bacteria show structural variations, even among strains within the same species living in the

Subchronic Toxicity of Microcystin-LR on Young Frogs (Xenopus laevis) and Their Gut Microbiota

open access: yesFrontiers in Microbiology, 2022
Although toxic effects of microcystins (MCs) in mammals and fish have been extensively studied, the effects of MCs on the immune system and gut microbiota of amphibians have not received sufficient attention. As MCs cause general damage to the vertebrate

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Nutrient enrichment destabilizes aquatic food webs through synchronization within and across trophic levels

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nutrient enrichment destabilizes ecosystems globally, but the mechanistic pathways underlying this effect in multi‐trophic communities remain unclear. To address this knowledge gap, we applied biodiversity–stability theory to multi‐trophic communities by partitioning ...

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

Recent Advances in the Use of Natural Deep Eutectic Solvents for Natural Product Sample Preparation: Focus on Purification, Characterization, and Sustainability

open access: yesJournal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT This review examines recent advances in the use of natural deep eutectic solvents (NaDES) for natural product sample preparation, with emphasis on extraction, purification, analytical compatibility, and sustainability. NaDES emerge as versatile, tunable, and biocompatible media that enhance the recovery and stability of diverse phytochemicals ...
