Plastics are recognized as a worldwide threat to the environment, possibly affecting human health and wildlife. Small forms of plastics such micro- nanoplastics can interact with other organic contaminants, potentially acting chemical carriers modulating their toxicity. In this study, we investigated toxicity polystyrene nanoparticles (Nano-PS) real-world environmental PAH mixture (Elizabeth River Sediment Extract, ERSE, comprised 36 detected PAHs) zebrafish embryos larvae. Embryos were...
The global accumulation of plastic waste has reached crisis levels. diverse and multilayered impacts on biological health prompts an evaluation these effects from a One Health perspective, through which the complexity processes can be integrated more clearly understood. Plastic particles ranging nanometers to meters in size are found throughout every ecosystem Earth, deepest marine trenches highest mountains. affects all layers organization, molecular cellular organismal, community,...
Zinc demonstrates protective and antioxidant properties at physiological levels, although these characteristics are not attributed moderate or high concentrations. toxicity has been related to a number of factors, including interference with defenses. In particular, the inhibition glutathione reductase (GR) suggested as possible mechanism for acute zinc in bivalves. The present work investigates biochemical effects non-lethal concentration on antioxidant-related parameters gills brown...
Plastics are world-wide pollutants that pose a potential threat to wildlife and human health. Small plastic particles, such as microplastics nanoplastics, easily ingested, can act Trojan Horse by carrying microorganisms pollutants. This study investigated the role of effect in toxicity nanoplastics vertebrate model organism, zebrafish (Danio rerio). First, we if this could affect nanoplastics. Second, analyzed it contribute biodistribution associated contaminants. And third, focused on its...
Hemocytes mediate a series of immune reactions essential for bivalve survival in the environment, however, impact harmful algal species and their associated phycotoxins upon system is under debate. To better understand possible toxic effects these toxins, Crassostrea gigas hemocytes were exposed to brevetoxin (PbTx-2). Hemocyte viability, monitored through neutral red retention MTT reduction assays, apoptosis (Hoechst staining) remained unchanged during 12 h exposure PbTx-2 concentrations up...
Phenolic compounds are widely present in forage. However, few studies have been carried out to investigate the presence of these animal products such as milk. In this study, total phenolic content (TPC) and ferric reducing-antioxidant power (FRAP) milk produced under agroecological conventional management systems southern Brazil were determined. Three compared: (a) agroecological, with intensive rotational grazing, also known Voisin grazing (ECO); (b) semi-intensive (SIC); (c) (CGR) (n = 8...
Malathion toxicity has been related to the inhibition of acetylcholinesterase and induction oxidative stress, while zinc shown possess neuroprotective effects in experimental clinical studies. In present study effect chloride (zinc) was addressed adult male Wistar rats following a long-term treatment (30 days, 300 mg/L tap water ad libitum) against an acute insult caused by single malathion exposure (250 mg/kg, i.p.). produced significant decrease hippocampal acetylcholinesterase, as well...
Analysis of the Pacific oyster Crassostrea gigas annotated genome revealed genes with conserved sequences belonging to typical cap 'n' collar Nrf2 domain, a major player in antioxidant protection, and domains cytoplasmic repressor (Keap1), but little is known about Nrf2/Keap1 induction bivalves. C. were exposed waterborne 10 30μM curcumin, inducer mammalian Nrf2. Curcumin disappeared from seawater after 10h, accumulated gills (10h) digestive gland (10-96h). A clear glutathione (GSH)-related...
Abstract: The wide use of the organophosphate insecticide malathion is accompanied by risk human exposure, especially in developing countries, which underlines need basic studies this area. Some reports have shown that low doses malathion, a repeated treatment regimen, are unable to reduce acetylcholinesterase (AChE) activity rat brain, contrast inhibitory effect acute treatment. In order investigate if AChE affected low‐level administration, female Wistar rats were exposed (50 and 100...
