  1. 21. Developmental exposure to mixtures of environmental pollutants : Studies on metabolism, developmental processes, and reproductive organs in zebrafish and chicken embryos

    Författare :Anna Mentor; Maria Jönsson; Patrick Babin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixtures; Developmental toxicology; Endocrine disrupting chemicals; Metabolism; Feminization; Zebrafish; Chicken embryo; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi; Biology with specialization in Environmental Toxicology; Biologi med inriktning mot miljötoxikologi;

    Sammanfattning : Humans and wildlife are continuously exposed to mixtures of environmental pollutants. Mixture toxicity can be challenging to predict due to interactions between chemicals and thus whole-mixture approaches are crucial in toxicology. LÄS MER

  3. 22. Estrogen regulation of non-Hodgkin lymphomas and its underlying mechanisms

    Författare :Dan Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Most non-Hodgkin lymphoma (NHL), including diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL), show a higher male to female incidence ratio. The reason for this is not clear, but epidemiological and experimental studies have suggested a role for estrogens in NHL acting via estrogen receptor β (ERβ). LÄS MER

  4. 23. Male reproductive health in environmental research : aspects of histological evaluation of testicular tissue

    Författare :Ellinor Spörndly-Nees; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : There is increasing concern that chemicals in the environment are causing male reproductive disorders in animals and humans. This thesis investigated different aspects of histological evaluation of testes, as a tool to measure effects of environmental chemicals on male reproductive health in wild and laboratory animals.

  5. 24. Exposure to xenobiotic chemicals disrupts metabolism, rhythmicity and cell proliferation in Drosophila melanogaster

    Författare :Hao Cao; Helgi B. Schiöth; Michael J. Williams; Jan Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; xenobiotics; metabolism; insulin signalling; circadian rhythm; carcinogen; Biomedical Laboratory Science; Biomedicinsk laboratorievetenskap;

    Sammanfattning : Most species are constantly exposed to xenobiotic chemicals through multiple routes. Among all categories of xenobiotics, phthalates and bisphenols are two of the most widely used plasticizers and can be found in polyvinyl chloride (PVC) materials, medical devices and even drinking water.

  7. 25. Adsorption and transformation of organic micropollutants in wastewater : New insights from 14C-labeling

    Författare :Alexander Betsholtz; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated carbon; ozonation; Organic micropollutants; pharmaceuticals; wastewater; transformation products; biological degradation; GAC-filters; adsorption; 14C-labeling;

    Sammanfattning : This thesis focuses on the removal of organic micropollutants and transformation products using ozone and activated carbon treatment processes. A combination of 14C-labeled and non-radiolabeled organic micropollutants was used to study aspects of micropollutant removal from novel perspectives. LÄS MER
