  1. 1. Testosterone and 17beta-oestradiol secretions in children and adolescents. Assay development, levels for comparison and clinical applications

    Författare :Carina Ankarberg-Lindgren; Göteborgs universitet; []
    Nyckelord :17beta-oestradiol; testosterone; sensitive assay; data for comparison; prepuberty; puberty; children; pubertal induction.;

    Sammanfattning : Accurate measurements of 17beta-oestradiol and testosterone are important in clinical settings of pubertal disorders and hormone replacement therapy among children. Most assays for measurement of these steroids are optimised for fertility investigations in adults and are not sensitive enough for quantification in children. LÄS MER

  3. 2. Galanin and NPY in the rodent brain: rapid effects of 17beta-estradiol and possible roles in hippocampal plasticity

    Författare :Susanne Hilke; Elvar Theodorsson; Tomas Hökfelt; Bruce S. McEwen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sex-hormones; Brain; Neuropeptides; Neurochemistry; Neurokemi;

    Sammanfattning : The neuropeptides galanin and neuropeptide Y (NPY) play an important role in the reproduction of rodents, e.g. by modulating the release of gonadal hormones, the nutritional status by effects on feeding behavior and also by influencing mating behavior. LÄS MER

  4. 3. Female stress incontinence and uterovaginal prolapse : collagen turnover and hormone sensitivity in urogenital tissue

    Författare :Lena Edwall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Stress incontinence; urogenital tissue; collagen turnover markers; estradiol- 17beta; estrone; testosterone; uterovaginal prolapse; menopause;

    Sammanfattning : Background: Prevalence of both stress urinary incontinence (SUI) and uterovaginal prolapse (UP) is high and rising with age. Risk factors include multiparity, obesity, chronic obstructive lung disease and previous gynecological surgery. The underlying pathology is still unknown but may include defective connective tissue.

  5. 4. Nuclear receptor functions in the central nervous system : clues from knockout mice

    Författare :Sandra Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Estrogen receptor; liver X receptor; 5alpha-androstane-3beta; 17beta-diol; brain development; neuronal degeneration; spinal cord; motor neuron.;

    Sammanfattning : The nuclear receptor (NR) superfamily is the largest known family of transcription factors in eukaryotes. In the 1980 s when the size of the NR family and the scope of the functions of its members were being discovered, tissue distribution studies revealed that the mRNAs of many of these receptors were expressed in the central nervous system.

  7. 5. Estrogen effects on different neurotransmitters in rat hippocampus : implications for cognitive function

    Författare :Nahid Karrar El-Bakri; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The past decade has witnessed a growing interest in estrogens and their activity in the central nervous system, which extends beyond the reproductive functions. Estrogen is known to interact with different neurotransmitter systems. LÄS MER
