Daphnia magna
The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...
متن کاملUptake and depuration of gold nanoparticles in Daphnia magna
This study presents a series of short-term studies (total duration 48 h) of uptake and depuration of engineered nanoparticles (ENP) in neonate Daphnia magna. Gold nanoparticles (Au NP) were used to study the influence of size, stabilizing agent and feeding on uptake and depuration kinetics and animal body burdens. 10 and 30 nm Au NP with different stabilizing agents [citrate (CIT) and mercaptou...
متن کاملBisphenol A migration from plastic materials: direct insight of ecotoxicity in Daphnia magna.
Bisphenol A (BPA) is an endocrine disrupting chemical (EDC) whose migration from food packaging is recognized worldwide. However, the real overall food contamination and related consequences are yet largely unknown. Among humans, children's exposure to BPA has been emphasized because of the immaturity of their biological systems. The main aim of this study was to assess the reproductive impact ...
متن کاملToxicity Assessment of Some Conventionally Manufactured Nanoparticles to Daphnia Magna
Background and purpose: Nanoparticles (NPs) are used in different industries, including electronics, pharmaceuticals, cosmetics, healthcare, and environmental processes. Therefore, it is necessary to evaluate their toxicity in the aquatic environment. Materials and methods: The acute toxicity of six different kinds of nano-sized particulates (SiO2, Fe2O3, Al2O3, TiO2, ZnO, and MgO) to Daphnia ...
متن کاملGenes mirror geography in Daphnia magna.
Identifying the presence and magnitude of population genetic structure remains a major consideration in evolutionary biology as doing so allows one to understand the demographic history of a species as well as make predictions of how the evolutionary process will proceed. Next-generation sequencing methods allow us to reconsider previous ideas and conclusions concerning the distribution of gene...
