  1. 1. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Författare :Mathieu Le Noir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Sammanfattning : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. LÄS MER

  2. 2. Effects of Endocrine Disrupting Chemicals on Human Endometrial Endothelial Cells In Vitro

    Författare :Malin Helmestam; Matts Olovsson; Anneli Stavreus-Evers; Yvonne Lundberg Giwercman; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endocrine disrupting chemicals; hormones; human endometrial endothelial cells; endometrium; estrogen; progesterone; cadmium; tamoxifen; mifepristone; bisphenol A; angiogenesis; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation. LÄS MER

  3. 3. Biodegradation of the Recalcitrant Endocrine Disruptor Nonylphenol

    Författare :Ana Soares; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm bioreactors; Miljöteknik; pollution control; Environmental technology; Teknik; Technological sciences; white-rot fungi; nonylphenol ethoxylates; endocrine-disrupting activity; contaminated soil; cold-adapted organisms; kontroll av utsläpp; Biotechnology; Bioteknik; biodegradation;

    Sammanfattning : Currently, over 100 high-volume chemicals have been classified as endocrine disrupters. One of these is nonylphenol, which was used as the model compound in this study. This substance originates mainly from the degradation of non-ionic surfactants (nonylphenol ethoxylates) which are widely used in industrial and domestic applications. LÄS MER

  4. 4. Interaction of Xenobiotics with the Glucocorticoid Hormone System in vitro

    Författare :Maria Johansson; Helen Håkansson; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; DDT; PCB; tolylfluanid; adrenal; CYP11B1; glucocorticoid receptor; endocrine disrupter; Biologi; Biology; Biologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : Persistent environmental pollutants were examined for their interaction with the glucocorticoid hormone system. The focus was placed on interference with the glucocorticoid synthesis and the glucocorticoid-signalling pathway in various in vitro test systems. LÄS MER

  5. 5. Steroidogenesis studied in a human adrenocortical cell line : effects of single chemicals and mixtures

    Författare :Åsa Ohlsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Sammanfattning : Steroidogenesis may be a target for endocrine disrupting chemicals; unfortunately data of such effects is limited. The aim of this thesis was to study effects on steroidogenesis of single chemicals and mixtures in the human adrenocarcinoma cell line H295R. Screening for effects on steroid secretion was performed by ELISA. LÄS MER
