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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marie Andersson; Uppsala universitet.; [2015]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  2. 2. Genetic mechanisms regulating proliferation and cell specification in the Drosophila embryonic CNS

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Shahrzad Bahrampour; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The central nervous system (CNS) consists of an enormous number of cells, and large cellular variance, integrated into an elaborate network. The CNS is the most complex animal organ, and therefore its establishment must be controlled by many different genetic programs. LÄS MER

  3. 3. Regulatory programs controlling profileration during Drosophila nervous system development

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Erika Gunnar; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The central nervous system (CNS) is the most complex organ in the body, responsible for complex functions, including thinking, reasoning and memory. The CNS contains cells of many different types, often generated in vast numbers. LÄS MER

  4. 4. Immunological aspects of maternal-foetal interactions in mice

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Marie Arvola; Uppsala universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Neonatal mice; milk; placenta; fetal rejection; IgG; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Sammanfattning : Mammalian pregnancy is an immunological paradox. The foetus, which expresses both paternal and maternal cell-surface molecules, has to be protected from rejection by the maternal immune system. At the same time, the mother has to have an efficient immune defence and must provide her offspring with antibodies. LÄS MER

  5. 5. Environmental pollutants and the reproductive system in birds Developmental effects of estrogenic compounds

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Cecilia Berg; Uppsala universitet.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; NATURAL SCIENCES Biology Organism biology Developmental biology; NATURVETENSKAP Biologi Organismbiologi 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
