  1. 1. GABA-steroid effects in healthy subjects and women with polycystic ovary syndrome

    Författare :Helena Hedström; Torbjörn Bäckström; Marie Bixo; Ian Milsom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allopregnanolone; isoallopregnanolone; gonadotropins; GABA-A receptor; women; polycystic ovary syndrome; saccade; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background: The progesterone metabolite allopregnanolone is involved in several clinical conditions in women, e.g. premenstrual dysphoric disorder. It is a very potent GABA-steroid with GABA-A receptor effects similar to other GABA-agonists, e. LÄS MER

  3. 2. Hormone replacement therapy : benefits and adverse effects

    Författare :Inga-Stina Ödmark; Mats Hammar; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hormone replacement therapy HRT ; bleeding pattern; progestogen; wellbeing; side effects; lipoprotein a ; Obstetrics and gynaecology; Obstetrik och gynekologi; obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Background: Numerous studies have shown that estrogen replacement therapy (ERT) is an effective treatment for vasomotor symptoms, insomnia and vaginal dryness. Beneficial effects have also been shown on lipid patterns and on the incidence of osteoporotic fractures. LÄS MER

  4. 3. Hormone replacement therapy and effects on mood

    Författare :Inger Björn; Inger Sundström-Poromaa; Torbjörn Bäckström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adverse effects; estradiol; hormone replacement therapy HRT ; mood; negative side effects; progestins;

    Sammanfattning : Background: During the past 5 decades, hormone replacement therapy (HRT) has been used, and appreciated for its beneficial effects, by millions of women in their menopause. As treatment for climacteric symptoms, estrogen is outstanding, and effects on hot flushes, vaginal dryness, and insomnia have been widely documented. LÄS MER

  5. 4. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis

    Författare :David Gunnarsson; Gunnar Selstam; Gunnar Nordberg; Per Leffler; Henrik Leffers; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Endocrine disruptors; reproductive toxicology; cadmium; phthalates; DEHP; MEHP; phytoestrogens; steroidogenesis; testosterone; Leydig cell; Molecular biology; 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

  7. 5. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Författare :Cecilia Berg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. LÄS MER
