  1. 1. Effects of early life exposure to flutamide on sexual development in Xenopus tropicalis

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Författare :Christopher Hampton; [2019]
    Nyckelord :;

    Sammanfattning : While endocrine disrupting chemicals have become a serious concern in human and environmental toxicology, many of the methods used for investigating developmental toxicity require long exposure periods, and thus can be technically challenging, labour intensive and expensive. For example, the current standard method, the Larval Amphibian Growth and Development Assay (LAGDA) has an exposure period of ³130 days. LÄS MER

  3. 2. Thyroid Endocrine Disruption of Propylparaben Assessed Using an Optimized Individual Xenopus tropicalis Metamorphosing Tadpole Exposure System

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Johannes Pohl; [2015]
    Nyckelord :Xenopus; Thyroid hormones; Endocrine disruption; Amphibian metamorphosis assay; Propylparaben; Hormonstörande ämnen; Propylparaben; Xenopus; Sköldkörtelhormoner;

    Sammanfattning : The anuran Xenopus tropicalis tadpole is an attractive model animal in toxicological evaluation of suspected thyroid disrupting xenobiotics. Due to its reliance of a functioning hypothalamic-pituitary-thyroid (HPT) axis for normal metamorphosis, effects on the HPT axis produces apical endpoints, which are easy to measure. LÄS MER

  4. 3. Polyhalogenated organic pollutants in amphibians

    L3-uppsats, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Pushkar Kulkarni; [2005]
    Nyckelord :2; 2 ; 4; 4 ; 5-pentabromodiphenyl ether; BDE 99; PBDE; tissue disposition; frogs; Xenopus tropicalis; polyhalogenated organic pollutants;

    Sammanfattning : Polyhalogenated organic pollutants are xenobiotics, which are believed to cause considerable environmental pollution and human health problems as a result of their persistence, toxicity, and transformation into hazardous metabolites. These chemicals are persistent and are biomagnificated in the ecosystem. LÄS MER
