  2. 1. Mechanisms controlling striatal projection neurone generation, from patterning to early differentiation

    Author : Håkan Toresson; Klinisk minnesforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pbx; meis; sonic hedgehog; small eye; pax6; gsh2; gsh1; cerebral cortex; striatum; telencephalon; mutant; development; mouse; embryo; retinoic acid; Clinical biology; Klinisk biologi;

    Abstract : The striatum is part of the telencephalon, the most anterior part of the vertebrate brain. From when it first can be identified, telencephalic morphology is highly complex and a wide range of mechanisms has been suggested to participate in its induction, patterning and neurogenesis.

  4. 2. Transcription factors involved in negative and positive gene regulation by glucocorticoids

    Author : Nanthakumar Subramaniam; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Steroid hormones, including glucocorticoids (GCs), control a wide variety of developmental and physiological responses in higher eukaryotic organisms. They pass through the plasma membrane and bind to specific receptor proteins inside the cell. READ MORE

  5. 3. Genetic mechanisms behind cell specification in the Drosophila CNS

    Author : Magnus Baumgardt; Stefan Thor; Angela Giangrande; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila melanogaster; nervous system development; cell specification; stem cells; cell proliferation; combinatorial coding; feedforward loop; Developmental biology; Utvecklingsbiologi;

    Abstract : The human central nervous system (CNS) contains a daunting number of cells and tremendous cellular diversity. A fundamental challenge of developmental neurobiology is to address the questions of how so many different types of neurons and glia can be generated at the precise time and place, making precisely the right connections.

  6. 4. Specification of unique neuronal sub-types by integration of positional and temporal cues

    Author : Daniel Karlsson; Stefan Thor; Mattias Alenius; Jeremy S. Dasen; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The nervous system contains vast numbers of neuronal sub-types, generated at specific time points, in the proper location, and in proper numbers. One of the fundamental issues in neurobiology is to understand the molecular genetic mechanisms that underlie the generation of this daunting neuronal diversity. READ MORE

  7. 5. Development of a Generic Model for Life Cycle Inventory and Environmental Assessment of Upstream Processes for Electronic Products

    Author : Anders Andrae; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-In-a-Package; electronic products; upstream processes; life cycle inventory; life cycle assessment;

    Abstract : The goal with the present thesis is to develop tools, methods and models to assess the upstream processes in the life cycle assessment (LCA) methodology for current and new electronic products. The goal is to get a better understanding on how to collect data to be used in a life cycle inventory (LCI) and use life cycle approaches to environmentally assess the electronics. READ MORE
