    Sammanfattning : Asthma means difficulty in breathing and is described as a chronic, inflammatory disorder that produces narrowing of the lower respiratory tract. The allergen-induced asthmatic bronchoconstriction is primarily caused by an IgE-mediated release of the mast cell mediators, histamine and eicosanoids (leukotrienes and prostanoids). LÄS MER

  3. 12. PARENTS´ EXPERIENCES AND REACTIONS WHEN AN UNEXPECTED FINDING IN THEIR FOETUS IS REVEALED AT A ROUTINE ULTRASOUND EXAMINATION

    Författare :Anna-Karin Larsson; Institutionen för hälsovetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The overall aim of this thesis was to describe parent’s experiences, reactions and needs in connection with a routine ultrasound examination during pregnancy when the foetus was found to have an abnormal ultrasound finding. The data collection began in February 2005 and the one year cohort study was completed by March 2006. LÄS MER

  4. 13. Translational Aspects of Erythropoietin Receptor and Hypoxia-Inducible Factors in Breast Cancer

    Författare :Anna-Maria Larsson; Institutionen för translationell medicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; Anemia; Hypoxia; Erythropoietin EPO ; EPO receptor EPOR ; Estrogen Receptor ER ; Hypoxia-Inducible Factors HIFs ; Tamoxifen Response; Proliferation;

    Sammanfattning : The main function of erythropoietin (EPO) is in hematopoiesis where EPO stimulates increased proliferation, survival and differentiation of erythrocytic precursors in response to hypoxia. The EPO effect is mediated via binding to the EPO receptor (EPOR), which induces activation of different intracellular signaling pathways. LÄS MER

  5. 14. On cholinergic mechanisms involved in ethanol reinforcement. A behavioral and neurochemical study in rodents

    Författare :Anna Larsson; Göteborgs universitet; []
    Nyckelord :Acetylcholine; Dopamine; Ethanol; Locomotor activity; Microdialysis; Nicotine; Nicotinic acetylcholine receptors; Rodents; Reward;

    Sammanfattning : Alcohol (ethanol) and smoking (nicotine) are commonly co-abused in human beings. Drugs of abuse interact with the brain mesolimbic dopamine system, an important part of the brain reward system. These dopaminergic neurons originate in the ventral tegmental area and project to e.g. LÄS MER
