The average ozone removal efficiency of these pharmaceuticals was 77%. Gibert et al. This thesis aimed to investigate outcomes of ozonation treatment of STP effluents with a special focus on pharmaceuticals, by combining chemical analysis and in vivo testing using zebrafish (Danio rerio). For the NP exposures, GFP expression was observed at 10 μg NP/L after 72 h (100 μg NP/L was toxic to the fish). Zebrafish (Danio rerio) has appeared as a valuable and popular model species to study the developmental and toxicological impact of environmental pollutants. Recently, with the development of transgenic technology 28, especially the applications of both luciferase (LUC) and green fluorescent protein (GFP) reporters in this field 29, monitoring efficiency and sensitivity have been dramatically improved. We propose that carefully-controlled laboratory experiments on different behavioral domains—including anxiety, aggression, and exploration—can increase our understanding of the ecotoxicological impacts of contaminants, since these domains are related to traits such as defense, sociality, and reproduction, directly impacting life-history traits. Supercritical CO The polybrominated diphenyl ethers (PBDEs) are a group of brominated flame retardants. But, there are also purely scientific reasons why ‘lower’ organisms, such as zebrafish, The synergistic toxicity of Cd(II) and Cu(II) to zebrafish (Danio rerio): Effect of water hardness. The paper presents various natural sorbents and some outcome of POPs sorption on these materials. The in vitro study of acetylcholinesterase activity in various fish species, such as arapaima (Arapaima gigas), peacock bass (Cichla ocellaris), tambaqui (Colossoma macropomum), zebrafish (Danio rerio), jaguar cichlid (Parachromis managuensis), streaked prochilod (Prochilodus lineatus), cobia (Rachycentron canadum), and tilapia (Oreochromis niloticus), have been proposed to be used in the detection of harmful physiological effects of pesticides to these aquatic organisms [4,6,[33][34]. Zebrafish are a well-established vertebrate animal model for toxicity, ... We addressed this by using a bioassay approach with zebrafish, Danio rerio¸ a well-known vertebrate model. For this reason, it is necessary to consider the use of alternative testing strategies or methods that reduce, refine, or replace (3Rs) the use of animals for assessing the toxicity of NMs. 30700607). 2014) and D. rerio. Evaluation of toxicological and teratogenic effects of carbosilane glucose glycodendrimers in zebrafish embryos and model rodent cell lines. This study demonstrates the efficacy of using the zebrafish model for studying the neurobehavioral effects of low-dose developmental BPA exposure. In addition, we summarize the current knowledge how different types of DNA damage, relevant either for the induction or treatment of cancer, are bypassed by TLS polymerases. Saili et al. Nanotechnology has rapidly promoted the development of a new generation of industrial and commercial products; however, it has also raised some concerns about human health and safety. Journal of Environmental Science and Health, Part A. Alterations in the Gut Microbiota of Zebrafish (Danio rerio) in Response to Water-Soluble Crude Oil Components and Its Mixture With a Chemical Dispersant. Enfin, l’étude de la transversalité de biomarqueurs peptidiques identifiés chez Gammarus fossarum a permis de définir les peptides communs à l’aide de l’ensemble des données protéomiques et transcriptomiques. Introduction. In addition, PFOS increased early thyroid development gene (hhex and pax8) expression in a concentration-dependent manner, decreased steroidogenic enzyme gene (CYP17, CYP19a, CYP19b) expression, and changed the expression pattern of estrogen receptor production genes (esr1, esr2b) after 500-µg/L PFOS treatment in zebrafish embryos. However, behaviour remained largely unaffected in zebrafish exposed to NDs. It is evident from the review that natural sorbents have demonstrated high removal capabilities for certain compounds. Animal (experimental) models are an indispensable tool in behavioral neuroscience research, including studying the central nervous system (CNS) disorders and screening novel neuroactive drugs. Two-dimensional gel electrophoresis revealed a total of 13 protein spots, whose expression levels were significantly altered by MP. Thus, more information is needed to understand the mechanisms associated with the potential toxicity of these nanomaterials in the aquatic environment. Pour cela, un logiciel d’exploration des séquences peptidiques a été développé permettant de proposer de potentiels biomarqueurs substituts dans le cas où les peptides définis ne sont pas applicables à certaines espèces de gammare.

Exposure to MT resulted in decreased vitellogenin concentrations. In conclusion, Piper sarmentosum extracts accelerated tissue regeneration, and extract concentrations at 60 µg/mL showed the highest toxicity levels for embryo viability. Our earlier studies indicated the high expression of a UV-damaged-DNA binding activity in zebrafish (Danio rerio) embryos at 12 h postfertilization (hpf). The aquatic environment is the main destination for many organic pollutants originating from human activity. Also, they can even react with nucleic acids resulting in several genetic injuries, thus causing adverse reactions to the body. The HPLC-MS/MS analysis found that PFNA concentrations were higher in male livers than in female livers with increasing significance in a dose-dependent manner. The transgenic zebrafish is developed and reported to be a more advanced system for monitoring environmental pollutants 29, 75. Les bases de données protéomiques ainsi produites ont permis l’analyse inter-population de 40 protéomes individuels de Gammarus pulex répartis sur deux sites de prélèvement (pollué vs référence). Our results establish a novel feedback pathway that modulates the p53 response and suggest that modulation of the p53 pathway by p53 isoforms might have an impact on p53 tumor suppressor activity. This study observed the effect of CA extract on the expression of IGF-1, IRS, and the linear growth of rotenone-induced zebrafish larvae. The QDs (ZnS and CdS) appear to cause more adverse effects singly than when tested combined. pxr (nr1i2) Chen et al. In this study, we used an experimental animal model to explore the developmental and cardiac toxicity of Pyrimethanil in aquatic vertebrates; we exposed zebrafish embryos to Pyrimethanil at concentrations of 2, 4, and 6 mg/L from 5.5 to 72 h post fertilisation. On the other hand, we characterized the process at a molecular level by analyzing several immune markers (il-1β, il-10, lysC, mpx, cyp1a) at different time points by qPCR. Acrolein affected the cardiac morphology and function of the embryos. The International Organization for Standardization (ISO) first published the zebrafish toxicity test in 1984 30. The results indicate that PFOS can act as an estrogen receptor agonist and thyroid hormone receptor antagonist. Microarray analysis revealed that for BBF and retene, drug metabolism pathways were induced, which were confirmed by subsequent studies of cyp1a gene expression. These results suggest that the PH domain of P-Rex1 is a tractable drug target and that these compounds might be useful for inhibiting P-Rex1 in other experimental contexts. Besides the traditional methods of chemical analysis, some biological technologies have been developed, such as gonadal morphology and histological comparative analysis, messenger RNA (mRNA), and protein levels of chorionic gonadotropin or vitellogenin (vtg). Zebrafish have been used as a model system in environmental toxicology studies. As a teleost, zebrafish has developed a complete immune system which is similar to mammals. Sensitivity to different contaminants makes the zebrafish an ideal model organism for environmental monitoring. Larval behavior tests were conducted using a ViewPoint Zebrabox. © 2013 SETAC. None of those studies consider in detail the adverse inflammatory effect that the antibiotic remaining in the water may cause to the fish. In many well-established protocols for teratogenicity and reproductive toxicology, the assumption appears to be that, if a given substance is teratogenic in fish embryos, one can assume that it will also be in human embryos (e.g., [21,22]). UVR exposure is known to cause developmental defects in a variety of organisms including aquatic species but little is known about the underlying molecular mechanisms. This included quantifying RNA knockdown, testing specificity of shRNA effects, and determining whether tissue-specific LOF could be achieved. Here, we conducted a field study to examine the relationship between salient environmental features and collective behavior in four populations of zebrafish. With the ban of conventional cigarettes from public spaces, electronic cigarette (E-cig) liquids have emerged as a nicotine replacement treatment for smoking cessation. Zebrafish as a model system to study toxicology Author: Dai, Yu‐Jie, Jia, Yong‐Fang, Chen, Na, Bian, Wan‐Ping, Li, Qin‐Kai, Ma, Yan‐Bo, Chen, Yan‐Ling, Pei, De‐Sheng Source: Environmental toxicology and chemistry 2014 v.33 no.1 pp. Therefore, using the methods described above as a tool to detect the presence of BPA is feasible. 11-17 ... and organic pollutants for toxicology. Therefore, epigenetic signatures are interesting candidates for linking environmental exposures to disease as well as informing on past exposures to stressors. The most common method of monitoring toxic heavy metals is toxicity experiments with both embryos and adult zebrafish 31, 32. Wild-type zebrafish (strain AB) were raised and maintained in E3 buffer (5 mM NaCl, 0.17 mM KCl, 0.33 mM CaCl 2, 0.33 mM MgSO 4, and 0.00001% Methylene Blue) under standard conditions (28.5°C and 14 hr/10 hr of light/dark cycles) .Embryo staging includes hours post fertilization (hpf) and morphological attributes .Animal care was in … This trend is partly explained by the many (30%) studies that focused on the zebrafish, Danio rerio, a species commonly used in ecotoxicological studies. . Danio rerio Pesticides are the mobile chemicals that are known to pollute the aquatic ecosystems. Exposure to 0.1μM 17β-estradiol or GSK4716 also led to larval hyperactivity. The zebrafish underwent chronic exposure for periods of 5, 10, and 20 days. Dioxin exposure to humans or other model organisms can cause chloracne, cancers, hepatotoxicity, diabetes, immune changes of gonadal, pulmonary tuberculosis, and other complications such as diabetes, skewed sex ratio, and infertility. DNA polymerases may therefore be potential targets to increase the sensitivity of cancer cells to chemotherapy drugs. In conclusion, the present study showed that endosulfan (0.01-10 μg L⁻¹) has toxic effects on zebrafish. The objectives of this study were to identify whether low-dose, developmental BPA exposure affects larval zebrafish locomotor behavior and whether learning deficits occur in adults exposed during development. Human health concerns of these agents have largely centered upon their potential to elicit reproductive and developmental effects. TALENs exhibited similar toxicity to CoDA ZFNs, with >50% of injected animals surviving to 3 days of life. .
