Article Synopsis
- The study investigates the toxicity of lanthanum, yttrium, and cerium oxides on the soil organism Enchytraeus crypticus, focusing on survival, reproduction, avoidance behavior, and DNA integrity.
- The research finds that the bulk forms of LaO have more significant effects than their nanoparticle counterparts, while YO nanoparticles are more toxic overall, impacting reproduction and causing DNA damage at lower concentrations.
- Results indicate that the toxicity of rare earth element oxides varies based on the type of element, concentration, exposure duration, and form, underscoring the need for careful risk assessment for soil ecosystems affected by these substances.
Background: This research proposes an easy to apply quality assurance pipeline for hyperspectral imaging (HSI) systems used for plant phenotyping. Furthermore, a concept for the analysis of quality assured hyperspectral images to investigate plant disease progress is proposed. The quality assurance was applied to a handheld line scanning HSI-system consisting of evaluating spatial and spectral quality parameters as well as the integrated illumination.

Several surveys on HD have been conducted to evaluate experiences in its management around the world. For the first time in Brazil, we analyze and report the management patterns of HD among pediatric surgeons in Brazil.

Article Synopsis
- * The study involved synthesizing CuO nanoparticles, which were characterized for their properties and morphology, and then coated with Agaricus blazei Murill polysaccharides to improve stability and reduce toxicity.
- * The resulting coated nanoparticles demonstrated antifungal activity against Candida infections and lower toxicity in adult zebrafish, suggesting they could be promising candidates for topical treatments in medical applications.
