  1. 1. Genomic and Peptidomic Characterization of the Developing Avian Brain

    Författare :Birger Scholz; Lennart Dencker; Eric Vilain; Uppsala universitet; []
    Nyckelord :Toxicology; Sex differentation; Sex determination; Sex chromosomes; Dosage Compensation; Genetic; Chickens; Coturnix; Gene Expression Profiling; Neuropeptides; Diencephalon; Toxikologi;

    Sammanfattning : Chicken and Japanese quail are commonly used models in developmental and sex specific neuroendocrine research. There is relatively little known about the mechanisms behind their sex specific brain development, especially regarding the impact of the sex chromosomes (male: ZZ, female ZW) in relation to gonadal hormones.

  3. 2. Mitochondrial plasmids, genetic conflicts and sex-determination in Silene vulgaris

    Författare :Helene Andersson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene vulgaris; sex-determination; mitochondrial plasmids; genetic conflicts; Botanik; Botany;

    Sammanfattning : Plants like all other eukaryotic organisms carry most of their DNA in the nucleus. In addition, plants also have both chloroplasts and mitochondria that contain their own genetic material. The genomes in chloroplasts and mitochondria control certain vital processes, but most often the organelles act under strict nuclear control. LÄS MER

  4. 3. Systematisk arbetsvärdering : ett lönesättningsinstrument i närbild

    Författare :Thomas Ericsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Job evaluation; wage determination; work of comparable worth; sex discrimination; equal opportunity; woman worker; labour legislation; food industry; local level; case study; model; statistical table;

    Sammanfattning : The subject of the thesis is systematic job evaluation for purposes of local wage determination for blue-collar jobs within the Swedish industry. The method is examined from a general wage-determination as well as from a gender equality perspective. The thesis is based on e.g. LÄS MER

  5. 4. Tomorrow is yesterday: early-life conditions shape ectotherm life histories

    Författare :Alexander Hansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; life history; ectotherm; temperature; development; sex; telomere; senescence;

    Sammanfattning : Life history theory seeks to explain the overwhelming diversity of resource allocation strategies in nature by exploring how evolutionary forces optimise survival and reproduction within an organism’s environment. Central to this theory is that resources are finite, and thus increased investment into one trait may reduce resources available for another trait. LÄS MER

  7. 5. Hormonal Regulation of Neural Stem Cell Proliferation and Fate Determination

    Författare :Karin Brännvall; Dan Lindholm; Sandra Ceccatelli; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neural stem cell; Proliferation; Fate determination; Hormones; Anabolic androgenic steroids; Neurovetenskap; Neurology; Neurologi;

    Sammanfattning : Stem cells have the capacity for both self renewal, and to form all cell types in the body. Interestingly, so called neural stem cells (NSCs) are found in the adult human brain, which is of significance both out of a developmental perspective and from a clinical point of view. LÄS MER
