  1. 1. Testosterone, 17β-estradiol and pubertal growth

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Anna-Karin Albin; Göteborgs universitet.; Gothenburg University.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; testosterone; estrogen; pubertal growth; growth hormone treatment;

    Sammanfattning : Background and aims: It is well established that the interaction of sex steroids with the growth hormone (GH)/ insulin-like growth factor 1 (IGF-1) axis is of major importance in children for normal pubertal growth. However, detailed understanding is still lacking. LÄS MER

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

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Carina Ankarberg-Lindgren; Göteborgs universitet.; Gothenburg University.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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. 3. Reproductive toxicology of endocrine disruptors effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

    Detta är en avhandling från Umeå : Molekylärbiologi (Teknisk-naturvetenskaplig fakultet)

    Författare :David Gunnarsson; Umeå universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi;

    Sammanfattning : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. LÄS MER

  4. 4. Actions of androgens and estrogens in experimental models of cardiovascular disease

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Johan Bourghardt Fagman; Göteborgs universitet.; Gothenburg University.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AR; atherosclerosis; AAA; androgens; testosterone; 2-methoxyestradiol;

    Sammanfattning : Men are at higher risk of developing both atherosclerotic cardiovascular disease and abdominal aortic aneurysm (AAA). Actions of sex steroids are hypothesized to underlie these gender differences. Testosterone, the major androgen, reduces atherosclerosis in male animal models but is suggested to promote AAA formation. LÄS MER

  5. 5. Serotonergic and steroidal influences on impulsive behaviour in rats

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :John L. Evenden; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; impulsivity; serotonin; 8-OH-DPAT; DOI; steroid; testosterone; Neurovetenskap; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Neurology; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : Impulsiveness is a trait contributing to the personality of all human beings to a greater and lesser extent. In a pathological form it can lead to impulsive behaviour which is an important component of many psychiatric and neurological disorders. LÄS MER
