  2. 1. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Author : Cecilia Berg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Abstract : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. READ MORE

  4. 2. Mechanisms of platelet-mediated fibroblast proliferation

    Author : Cecilia Berg; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Wound healing is a multicomponent event that involves a network of molecular and cellular crosstalk between cells, including leukocytes, platelets and fibroblasts. Despite increased knowledge over the past decades regarding the regulation of cell and tissue growth, the inter- and intracellular systems that control wound healing are incompletely understood.

  5. 3. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems

    Author : Cecilia Hahn Berg; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; trypsin; SDS elutability; statherin; salivary proteins; salivary pellicle; proline-rich proteins; plaque control; mucins; microbial adhesion; lubrication; krillase; intraoral friction; hydroxyapatite; gelatin; exchange; enzymes; ellipsometry; dental plaque; degradation; colloidal probe; calcium-induced precipitation; adsorption; atomic force microscopy; total internal reflectance fluorescence spectroscopy;

    Abstract : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. READ MORE

  6. 4. Endocrine Disruption in Amphibians : Developmental Effects of Ethynylestradiol and Clotrimazole on the Reproductive System

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

  7. 5. Ontogenetic Characterization of Müllerian Duct Development and Expression of anti-Müllerian hormone and Other Genes : New Endpoints in the Frog Xenopus tropicalis Test System

    Author : Erika Jansson; Cecilia Berg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The amphibian model-species Xenopus tropicalis is used in reproductive toxicology studies. Lifecycle studies are requested but they are time consuming and susceptible to several of the risks attributed to long-term studies. READ MORE
