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

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

    Abstract : 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.

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Hormonal Regulation of Neural Stem Cell Proliferation and Fate Determination

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

    Abstract : 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. READ MORE

  7. 5. Gender inequity in child survival : travails of the girl child in rural north India

    Author : Anand Krishnan; Nawi Ng; Peter Byass; Chadrakant Pandav; Per Ashorn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Conditional cash transfers; girl child; inequities; gender; prejudice; mortality; non-specific effects; sex; socio-economic; vaccines; Epidemiology; epidemiologi;

    Abstract : Background: While substantial progress has been made globally towards achieving United Nations Millennium Development Goal 4 (MDG 4) on child mortality, the decline is not sufficient to reach the targets set for 2015. The South Asian region, which includes India, was to achieve the MDG 4 target of 39 deaths per 1000 live births by 2015 but was estimated to have reached only 61 by 2011. READ MORE
