  1. 16. Mediators of synaptic activity in anxiety- and depression-related behaviors

    Författare :Carly Kiselycznyk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Depression and anxiety are leading causes of years lost to disability, despite antidepressants being among the most commonly prescribed medications. Most currently prescribed antidepressants were found serendipitously rather than from an understanding of the biological mechanisms underlying depression. LÄS MER

  3. 17. The accessibility and chemical activity of polycyclic aromatic hydrocarbons in soil

    Författare :Fredrik Reichenberg; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Remediation; Bioavailability; Soil and sediment pollution; Environmental chemistry; Miljökemi;

    Sammanfattning : This thesis proposes the use of two concepts: accessibility and chemical activity. Accessibility describes the mass quantity of PAHs that is or can become available within a given time span and under given conditions. LÄS MER

  4. 18. MODELLING-BASED TEACHING IN CHEMISTRY IN A MULTILINGUAL CONTEXT : A tool to explore and visualise the non-spontaneous and abstract?

    Författare :Lizette Widing; Pernilla Nilsson; Pernilla Granklint Enochson; Karina Adbo; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The thesis aims to investigate modelling-based teaching in the multilingual context. Modelling-based teaching concerns when students create, discuss, and evaluate representations to visualise concepts and processes. In this thesis, modelling-based teaching has been used in polymer chemistry at a Swedish secondary school. LÄS MER

  5. 19. Progesterone in human parturition : progesterone and 5α-pregnane-3,20-dione in relation to human myometrial activity

    Författare :Mats Löfgren; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This study was undertaken to evaluate the relationship of progesterone and 5α-pregnane-3,20-dione (5αDHP), a major progesterone metabolite, to human parturition. The serum concentrations of 5αDHP prior to, during and following parturition were to be established, as well as its maternal and fetal concentration in different modes of delivery. LÄS MER

  7. 20. Regulation of Breathing under Different Pulmonary Conditions

    Författare :Esther Rieger-Fackeldey; Gunnar Sedin; Anders Jonzon; Richard Sindelar; Andreas Schulze; Richard Martin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Control of breathing; Pulmonary Stretch Receptor; Phrenic Nerve Activity; Respiratory Distress Syndrome; Surfactant; Partial Liquid Ventilation; Assisted Ventilation; Pediatrik; Paediatric medicine; Pediatrisk medicin;

    Sammanfattning : The breathing pattern of preterm infants is immature and is associated with a variety of reflexes. In a patient on the ventilator these reflexes interfere with spontaneous breathing. A better understanding of the immature control of breathing could lead to further improvements in ventilatory techniques. LÄS MER
