  1. 6. Estrogen-inducible neuropeptides in the rat brain: role in focal ischemic lesions

    Författare :Annette Theodorsson; Elvar Theodorsson; A: Langmoen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Estrogen; neuropeptides; galanin; cerebral ischemia; middle cerebral artery occlusion; Neurochemistry; Neurokemi;

    Sammanfattning : Sex steroids in general and estrogens in particular – in addition to their effects on the reproductive organs – affect a large number of crucial bodily functions, including “higher” brain functions.Neuropeptides constitute the phylogenetically oldest neurotransmitter system and are currently thought to act mainly during stress, disease or injury.

  3. 7. Effects of oestrogen on haemodynamic and vascular reactivity - A study in animal models and humans

    Författare :Lisa Brandin; Göteborgs universitet; []
    Nyckelord :adrenergic reactivity; endothelium; haemodynamic; hypertension; oestrogen; postmenopausal women; resistance arteries; spontaneously hypertensive rats; stress;

    Sammanfattning : Effects of Oestrogen on Haemodynamic and Vascular Reactivity A study in animal models and humans Lisa Brandin Institute of Medicine, Department of Emergency and Cardiovascular Medicine, Sahlgrenska University Hospital/Östra, Sahlgrenska Academy, Göteborg University, Göteborg, Sweden ABSTRACT Previous studies have shown that oestrogen, the female sex hormone, plays a protective role in the cardiovascular system. However the site of action remains incompletely understood. LÄS MER

  4. 8. The role of estrogen receptors in the auditory system

    Författare :Konstantina Charitidi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Both laboratory and clinical studies have previously demonstrated estrogenic effects on auditory function. The overall scope of this study was to investigate the physiological and molecular involvement of estrogens and estrogen receptors alpha (ERα) and beta (ERβ) in hearing physiology. LÄS MER

  5. 9. The dose-dependent effects of estrogens on ischemic stroke

    Författare :Jakob Ström; Annette Theodorsson; Elvar Theodorsson; Mats Hammar; Torbjörn Bäckström; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Estrogens are a group of female sex hormones that in addition to central roles in reproductive functions also have profound impact on for example brain development, blood vessels, bone tissue, metabolism and the immune system. The dominant endogenous production sites for estrogens in females are the ovaries and adipose tissue, while exogenous sources include combined contraceptive hormone treatments and menopausal hormone therapy.

  7. 10. Strategies for Monitoring of Endocrine Disrupting Chemicals in Aquatic Environment

    Författare :Pär Hallgren; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vitellogenin; Endocrine disruption; alkali-labile phosphate; Carassius carassius; steroid hormones; Oncorhynchus mykiss; membrane exraction; supercritical fluid extraction; GC;

    Sammanfattning : The protein biomarker vitellogenin in fish is discussed alongside alterative strategies for monitoring of endocrine disrupting chemicals. The first objective was to find a cheap, robust and generic method for the quantification of vitellogenin. LÄS MER
