  1. 1. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism

    University dissertation from Xanto Grafiska AB

    Author : Jessica Abbott; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; embryologi; ontogeni; animal morphology; embryology; Utvecklingsbiologi; Damselflies; Colour polymorphism; Development; Frequency-dependence; Morphology; growth animal ; ontogeny; Animal anatomy; Development biology; Djurs anatomi och morfologi; Population divergence; Animal ecology; Djurekologi;

    Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations.

  2. 2. Novel Treatment Modalities for High-Risk Neuroblastoma Studies in Animal Models

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Dieter Fuchs; Faranak Azarbayjani; Rolf Christofferson; Sven Påhlman; [2009]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; neuroblastoma; bevacizumab; SU11248; GMX1778; GMX1777; animal model; VETERINARY MEDICINE Medicine; VETERINÄRMEDICIN Medicin;

    Abstract : Neuroblastoma, the most common extracranial solid tumor of childhood, is a heterogeneous tumor. In some patients, the tumor can go into spontaneous regression and disappear whereas other patients have rapidly growing tumors with a poor prognosis. READ MORE

  3. 3. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    University dissertation from Department of Animal Physiology, Lund University

    Author : Mariann Sondell; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Abstract : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. READ MORE

  4. 4. The control of growth and metabolism in Caenorhabditis elegans

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Medicinska fakulteten)

    Author : Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi;

    Abstract : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size.In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. READ MORE

  5. 5. Temporal dynamics of brain and hormone changes during parr-smolt transformation in salmon

    University dissertation from Department of Zoology, Lund University

    Author : Lars Ebbesson; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal morphology; Animal anatomy; growth hormone; metamorphosis; thyroid hormones; neural plasticity; Djurs anatomi och morfologi;

    Abstract : This thesis describes a series of studies designed to elucidate brain circuitry changes during parr-smolt transformation (smoltification) in salmon. The studies revealed sequential orderly chemical and structural changes of the brain. READ MORE
