  1. 1. Endocrine disruption in fish Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome

    Author : Tove Porseryd; Inger Porsch Hällström; Ioanna Katsiadaki; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 17α-ethinylestradiol; endocrine disrupting chemical; fish; behavior; fertility; transcriptome; RNA sequencing; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. READ MORE

  2. 2. Endocrine Disruption in Amphibians Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Irina Gyllenhammar; Cecilia Berg; Ingvar Brandt; Lena Holm; Joakim Larsson; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Test system; Xenopus tropicalis; Rana temporaria; sex ratio; sex differentiation; fertility; aromatase; ovary; testis; oviduct; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Amphibian populations are declining world-wide and one of the suggested reasons is environmental pollutants. Studies of long-term effects on the reproductive system in frogs following larval exposure to environmental pollutants are scarce. It is therefore important to develop methods to study developmental reproductive toxicity in amphibians. READ MORE

  3. 3. The juvenile three-spined stickleback model organism for the study of estrogenic and androgenic endocrine disruption in laboratory and field

    University dissertation from Stockholm : Institutionen för systemekologi

    Author : Edda Hahlbeck; Bengt-Erik Bengtsson; Poul Bjerregaard; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; endocrine disruption; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi;

    Abstract : Industrial and domestic sewage effluents have been found to cause reproductive disorders in wild fish, often as a result of the interference of compounds in the effluents with the endocrine system. This thesis describes laboratory-based exposure experiments and a field survey that were conducted with juveniles of the three-spined stickleback, Gasterosteus aculeatus. READ MORE

  4. 4. Endocrine modulators and sexual differentiation in Japanese quail : With emphasis on the neuroendocrine system

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Krister Halldin; Ted Ebendal; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; Japanese quail; sexual behavior; endocrine disruption; sexual differentiation; estrogen; estrogen receptors; avian; Biologi; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi; Ecotoxicology; ekotoxikologi;

    Abstract : Chemical disruption of the endocrine system in various animal species is currently attracting considerable interest, but avian models are not yet widely used in studying endocrine disturbances. This thesis shows the occurrence of alterations in sexual behavior and reproductive organs in adult Japanese quail (Coturnix japonica) following embryonic exposure to estrogen-like chemicals.

  5. 5. Strategies for Monitoring of Endocrine Disrupting Chemicals in Aquatic Environment

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pär Hallgren; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; vitellogenin; Endocrine disruption; alkali-labile phosphate; Carassius carassius; steroid hormones; Oncorhynchus mykiss; membrane exraction; supercritical fluid extraction; GC;

    Abstract : The protein biomarker vitellogenin in fish is discussed alongside alterative strategies for monitoring of endocrine disrupting chemicals. The first objective was to find a cheap, robust and generic method for the quantification of vitellogenin. READ MORE
