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

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Miljötoxikologi

    Author : Christopher Hampton; [2019]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

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

    Abstract : 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. READ MORE

  4. 3. Polyhalogenated organic pollutants in amphibians

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

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

    Abstract : 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. READ MORE
