  1. 31. Methodological considerations in epidemiological studies in perinatal medicine

    Författare :Dominika Modzelewska; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; gestational duration; preterm delivery; familial aggregation; heritability; variability; birthweight; small for gestational age; neonatal outcomes;

    Sammanfattning : This thesis is based on two projects, each consisting of two papers. In these two projects we investigated factors affecting the variability in gestational duration, and associations between maternal diet and neonatal outcomes. LÄS MER

  3. 32. Neonatal hypoxic ischemic encephalopathy : inflammation and therapies

    Författare :Elena Di Martino; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neonatal hypoxic ischemia (HI) is a severe condition characterized by a complex pathophysiology. The lack of oxygen (hypoxia) and blood flow (ischemia) leads to neuronal cell death via necrosis and apoptosis, and a consequent post-ischemic inflammation. HI brain injury may lead to seizures, cognitive and motor impairments, and death. LÄS MER

  4. 33. Interplay between DNA repair pathways at replication forks in mammalian cells

    Författare :Fredrik Johansson; Dag Jenssen; Klaus Erixon; Harry Vrieling; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Toxicology; Toxikologi;

    Sammanfattning : Cellular DNA is continuously being damaged by various agents of both endogenous and exogenous origin including a wide range of chemical compounds, UV-light and ionizing radiation. In order to remove lesions from the DNA and maintain genomic stability, different repair processes have evolved. LÄS MER

  5. 34. Carbohydrate dynamics and interactions studied by NMR spectroscopy

    Författare :Olof Engström; Göran Widmalm; Niklas Hedin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The combination of NMR spectroscopy and molecular dynamics (MD) simulations are powerful tools in the studying of bioorganic molecules in solution. In this thesis two such studies are presented with focus on the NMR aspect. LÄS MER

  7. 35. Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

    Författare :Johan Billing; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3-dipolar cycloaddition; 3-triazoles; 2; 1; molecular recognition; artificial receptors; sugar amino acids; cyclic peptides; macrocycles; Organic chemistry; Organisk kemi;

    Sammanfattning : Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. LÄS MER
