Small RNA Sequencing Based Identification of MiRNAs in Daphnia magna. [PDF]

PLoS ONE, 2015
Small RNA molecules are short, non-coding RNAs identified for their crucial role in post-transcriptional regulation. A well-studied example includes miRNAs (microRNAs) which have been identified in several model organisms including the freshwater flea ...

Daphnia magna, a Host for Evaluation of Bacterial Virulence [PDF]

Applied and Environmental Microbiology, 2012
ABSTRACT We show that Daphnia magna can be used to assess acute virulence of pathogens relevant to human health, such as Pseudomonas aeruginosa or Photorhabdus asymbiotica . Analysis of bacterial mutants suggests that P.

No evidence for genetic sex determination in Daphnia magna

Royal Society Open Science, 2021
Mechanisms of sex determination (SD) differ widely across the tree of life. In genotypic sex determination (GSD), genetic elements determine whether individuals are male or female, while in environmental sex determination (ESD), external cues control the

Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

DIXENIC CU LTURE OFDAPHNIA MAGNA, STRAUS

The Biological Bulletin, 1970
1. Daphnia magna can be grown for at least 200 generations, axenically or in crude cultures, in a defined mineral medium, enriched with vitamin B12 and thiamine and 1 ml/100 of a dilute organic medium, when fed with Chlamydomonas reinhardi and Scenedesmus obliquus.2. The organic enrichment is essential for maintaining continued fertility of D. magna.3.

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

Journal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

Integrating anaerobic and photochemical processes: UV–vis‐driven post‐treatment for micropollutant abatement and toxicity control in UASB secondary effluent

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Upflow anaerobic sludge blanket (UASB) reactors are widely used in low‐ and middle‐income countries, but secondary effluents may still contain organic micropollutants and residual toxicity. This study evaluated UV–Vis photolysis and UV/H2O2 as post‐treatment options for UASB secondary effluent (SE), integrating micropollutant ...
