  1. 1. 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; Uppsala universitet.; [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

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Roos; Uppsala universitet.; [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

  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; Uppsala universitet.; [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. 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; Södertörns högskola.; Södertörns högskola.; Uppsala universitet.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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; Cypermethrin; copper; glyphosate; behaviour; hormones; pheromones; olfaction; 11-ketotestosterone 11-KT ; 17α; 20β-dihydroxy-4-pregnen-3-one 17; 20β-P ; reproduction;

    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.

  5. 5. Developmental Neurotoxicity of Environmental Pollutants : Effects on neuronal protein markers after neonatal exposure

    University dissertation from Uppsala : Uppsala University, Department of Organismal Biology

    Author : Iwa Lee; Uppsala universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental neurotoxicity; Neonatal exposure; Protein markers; Environmental pollutants; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

    Abstract : This thesis focused on investigations of the developmental neurotoxic effects of bisphenol A (BPA) or perfluorohexane sulfonate (PFHxS), after a single neonatal exposure, during a critical period of the brain development in mice.BPA is a well-known industrial chemical used in the production of polymer products and PFHxS is used as an industrial additive as a surfactant.
