Histopathological Changes of Zebrafish (Danio rerio) Ovaries Exposed to Sub-lethal Concentrations of Methyl Paraben
Paraben compounds are used widely as preservatives to inhibit microbial growth and extend used in pharmaceuticals, hygienic, cosmetics, care products. They pose the potential for reproductive toxicity for users. This paper provides an overview of the applications of histopathological biomarkers in reproductive toxicity in zebrafish caused by methylparaben. The present study investigated the cha...
متن کاملthe effects of cooperative versus individual directed reading thinking activities on students inferential and referential questions
two groups of students were assigned as experimental and control ones, and were given instruction on directed reading-thinking activities and after some treatment, they were post-tested. although the initial pre-test did not show any significant differences, the final post-test result revealed that the cooperative reading comprehension helped the experimental group. the cooperative students’...
15 صفحه اولResponse of Daphnia Magna to Pulsed Exposures of Chlorpyrifos
Because aquatic organisms can be exposed to contaminants in an episodic manner, it is necessary to determine whether standard toxicity tests adequately simulate the toxicity of short-lived compounds, such as the organophosphate insecticide chlorpyrifos (CPF). We conducted experiments to evaluate the effect of binary combinations of concentration, duration, and interval of CPF exposures to Daphn...
متن کاملThe Effects of Natural and Anthropogenic Microparticles on Individual Fitness in Daphnia magna
Concerns are being raised that microplastic pollution can have detrimental effects on the feeding of aquatic invertebrates, including zooplankton. Both small plastic fragments (microplastics, MPs) produced by degradation of larger plastic waste (secondary MPs; SMPs) and microscopic plastic spheres used in cosmetic products and industry (primary MPs; PMPs) are ubiquitously present in the environ...
متن کاملAnalysis of Sub-Lethal Toxicity of Perfluorooctane Sulfonate (PFOS) to Daphnia magna Using 1H Nuclear Magnetic Resonance-Based Metabolomics
¹H nuclear magnetic resonance (NMR)-based metabolomics was used to characterize the response of Daphnia magna after sub-lethal exposure to perfluorooctane sulfonate (PFOS), a commonly found environmental pollutant in freshwater ecosystems. Principal component analysis (PCA) scores plots showed significant separation in the exposed samples relative to the controls. Partial least squares (PLS) re...
