  1. 11. Towards application of activated carbon treatment for pharmaceutical removal in municipal wastewater

    Författare :Victor Kårelid; Gen Larsson; Gunno Renman; Ola Svahn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced wastewater treatment; granular activated carbon; powdered activated carbon; municipal wastewater treatment; pharmaceutical removal; Bioteknologi; Biotechnology;

    Sammanfattning : Many pharmaceuticals are found in municipal wastewater effluents due to their persistence in the human body as well as in conventional wastewater treatment processes. This discharge to the environment can lead to adverse effects in aquatic species, such as feminization of male fish. LÄS MER

  3. 12. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

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

    Sammanfattning : 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. LÄS MER

  4. 13. Roles of ERα and ERβ in Normal and Disrupted Sex Differentiation in Japanese Quail

    Författare :Anna Mattsson; Björn Brunström; Krister Halldin; Lena Sahlin; Uppsala universitet; []
    Nyckelord :Toxicology; sex differentiation; estrogen receptor; sexual behavior; endocrine disruption; Japanese quail; Toxikologi;

    Sammanfattning : Exposure to xenoestrogens during development has been shown to impair sexual differentiation in various species. The major aim of this thesis was to elucidate the respective roles of the two estrogen receptors ERα and ERβ in normal and disrupted differentiation of sex organs and copulatory behavior in the Japanese quail (Coturnix japonica).

  5. 14. Genome Evolution and Niche Differentiation of Bacterial Endosymbionts

    Författare :Kirsten Maren Ellegaard; Siv Andersson; Andrés Moya; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; niche; habitat; endosymbiont; gut microbiome; honey bee; Wolbachia; comparative; genomics;

    Sammanfattning : Most animals contain chronic microbial infections that inflict no harm on their hosts. Recently, the gut microflora of humans and other animals have been characterized. However, little is known about the forces that shape the diversity of these bacterial communities. LÄS MER

  7. 15. Hormonal regulation of hepatic cholesterol and lipoprotein metabolism : effects of estrogen and growth hormone

    Författare :Paolo Parini; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :aging; atherosclerosis; bile acids; estrogen; estrogen receptor; cholesterol; growth hormone; growth hormone receptor; cholesterol 7[alpha]-hydroxylase; high density lipoprotein; hydroxy-methylglutaryl-coenzyme A reductase; hormones; hypercholesterolemia; hypophysectomy; insulin-like growth factor-I; low density lipoproteins;

    Sammanfattning : Coronary heart disease is the result of the progression of atherosclerotic lesions, and represents the major cause of death in western countries. Age, male sex, plasma cholesterol, hypertension and smoking are major risk factors for atherosclerosis. LÄS MER
