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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Mentor; Maria Jönsson; Patrick Babin; [2020]
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Cellular transport and secretion of the cyanobacterial neurotoxin BMAA into milk and egg Implications for developmental neurotoxicity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Marie Andersson; Ingvar Brandt; Cynthia de Wit; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; BMAA; beta-N-methylamino-L-alanine; milk; secretion; amino acid transporter; autoradiography; metabolism; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The cyanobacterial amino acid β-N-methylamino-L-alanine (BMAA) is a neurotoxin implicated in the etiology of neurodegenerative diseases. Cyanobacteria are cosmopolitan organisms present in various environments. READ MORE

  3. 3. In Vitro Studies of Adrenocorticolytic DDT Metabolites, with Special Focus on 3-methylsulfonyl-DDE

    University dissertation from Uppsala, Sweden : Acta Universitatis Upsaliensis

    Author : Vendela Asp; Ingvar Brandt; Ulrika Bergström; Olle Söder; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicity; 3-methylsulfonyl-DDE; CYP; adrenal cortex; metabolic activation; steroid hormones; Y-1; H295R; mitotane; adrenocortical carcinoma; NATURAL SCIENCES Biology Cell and molecular biology Toxicology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Toxikologi; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The DDT metabolite 3-methylsulfonyl-DDE (3-MeSO2-DDE) is bioactivated by cytochrome P450 11B1 (CYP11B1) in the adrenal cortex of mice and forms irreversibly bound protein adducts, reduces glucocorticoid secretion, and induces cell death selectively in cortisol-producing adrenocortical cells. 3-MeSO2-DDE has therefore been proposed as a lead compound for an improved adrenocortical carcinoma (ACC) therapy.

  4. 4. The Otter (Lutra lutra) in Sweden Contaminants and Health

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Roos; Jan Örberg; Björn Brunström; Katrin Lundstedt-Enkel; Susan Shaw; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Otter Lutra lutra ; PCB; DDT; PFAAs; reproduction; bone; time trends; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : In the 1950s the otter started to decline in numbers and distribution in Sweden and other parts of Europe. In 1972 a game law came into force, listing otter as a species that if found dead should be reported and sent to the authorities. The numbers of dead otters reported from different areas indicate population status and distribution. READ MORE

  5. 5. Pheromonal Mediated Behaviour and Endocrine Responses in Salmonids : The impact of Cypermethrin, Copper, and Glyphosate

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Alia Jaensson; Ingvar Brandt; Håkan Olsen; Kjell Döving; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cypermethrin; copper; glyphosate; behaviour; hormones; pheromones; olfaction; 11-ketotestosterone 11-KT ; 17α; 20β-dihydroxy-4-pregnen-3-one 17; 20β-P ; reproduction; NATURAL SCIENCES Biology Cell and molecular biology Toxicology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Toxikologi; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr.  Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes.
