Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Untreated Hair Dye Effluents Enter the Environment: Are They a Threat to Human Health?

Environmental Toxicology, EarlyView.
ABSTRACT The effluents generated during the process of hair dyeing exhibit a complex composition, comprising chemical compounds with varying toxicity levels. While the adverse impact of hair dyes on human health is acknowledged, there is a notable absence of studies addressing the toxicity associated with effluents produced during these activities. The

Comprehensive Evaluation of Bisphenol A Toxicity Reveals Neurobehavioral, Metabolic, and Reproductive Impairments in Girardia tigrina

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a common industrial chemical used in plastics and consumer products, is increasingly detected in aquatic environments, raising serious concerns about its potential ecological impacts. This study evaluated the sublethal and acute toxic effects of BPA on the freshwater planarian Girardia tigrina, a recognized model for ...

Organic matter characteristics in yedoma and thermokarst deposits on Baldwin Peninsula, west Alaska [PDF]

, 2018
As Arctic warming continues and permafrost thaws, more soil and sedimentary organic matter (OM) will be decomposed in northern high latitudes. Still, uncertainties remain in the quality of the OM and the size of the organic carbon (OC) pools stored in ...

Phthalate Metabolite, Mono(2‐Ethyl‐5‐Hydroxyhexyl) Phthalate (MEHHP), Promotes Uterine‐Fibroid–Associated Phenotypes in Myometrial Stem Cell‐Derived 3D Organoids

Environmental Toxicology, EarlyView.
ABSTRACT This study investigates how phthalate exposure contributes to uterine fibroid (UF) development by studying the effects of the Mono‐(2‐ethyl‐5‐hydroxyhexyl) phthalate (MEHHP), a metabolite of Di(2‐ethylhexyl) phthalate, on myometrial stem cells (MMSCs).

Effects of Tributyltin Chloride on Human Neuronal Differentiation and Mice Brain Development

Environmental Toxicology, EarlyView.
ABSTRACT According to the developmental origins of health and disease hypothesis, perinatal exposure to an environmental toxicant during the development of the nervous system could cause a permanent cellular modification that may promote the appearance of neurodegenerative diseases at an older age.
