Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Antimycobacterial and cytotoxicity activity of microcystins [PDF]
The present work aimed to evaluate the antimycobacterial activity and cytotoxicity of Microcystis aeruginosa toxins, the MC-LR variant and purified extract of [D-Leu(1)] microcystin-LR.The antimicrobial activity of M. aeruginosa extract and microcystin was evaluated by resazurin microtiter assay against Mycobacterium tuberculosis, M.

Studies on the immunosuppressive effects and detection of naturally-occuring toxins [PDF]
Episodes of toxin-producing phytoplankton occur worldwide, causing both animal and human fatalities. Toxicity occurs through consumption of phycotoxins, including azaspiracid, which accumulate in filter-feeding shellfish. Microcystins are hepatotoxins,

Phytotoxicity associated to microcystins: a review [PDF]
Microcystins (MC) are the most studied toxins of cyanobacteria since they are widely distributed and account for several cases of human and animal poisoning, being potent inhibitors of the serine/threonine protein phosphatases 1 (PP1) and 2A (PP2A). The phosphatases PP1 and PP2A are also present in plants, which may also suffer adverse effects due to ...

A seasonal time series metatranscriptome dataset suggests that neutralising hydrogen peroxide in Microcystis blooms requires a complex division of labour that is further complicated by seasonality and bloom development. ABSTRACT Cyanobacterial harmful algal blooms (cHABs) are expanding globally and often involve toxin‐producing species such as ...

A Global Analysis of the Relationship between Concentrations of Microcystins in Water and Fish
Cyanobacteria, the primary bloom-forming organisms in fresh water, elicit a spectrum of problems in lentic systems. The most immediate concern for people and animals are cyanobacterial toxins, which have been detected at variable concentrations in water ...

First report of microcystins in Taiwan [PDF]
This is the first report on microcystins from Microcystis aeruginosa Kützing in Taiwan. A total of nine strains of cyanobacteria have been isolated from eutrophic aquaculture ponds and water reservoirs. By mouse toxicity assay, six of the nine strains had LD100 in the range of 25-100 mg per kg mouse for dried bacterial mass. Microcystin-LR and -RR were

How Epitranscriptomic Machinery Senses Environmental Cues
Exogenous exposures, microenvironmental signals, and intracellular metabolic or redox states can alter RNA‐modification machinery through catalytic chemistry, signaling‐dependent PTMs, compartmental redistribution, or changes in abundance and composition.
