  1. 1. Engineering of Human Fetal Hemoglobin

    Författare :Karin Kettisen; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fetal hemoglobin; protein engineering; recombinant protein production; protein purification; chromatography; oxygen carrier; redox reactions; net surface charge; DNA cleavage;

    Sammanfattning : In blood, the oxygen-transporting protein hemoglobin (Hb) governs the oxygenation of cells and tissues. Naturally, this protein has claimed a place in the center of the research field of artificial oxygen therapeutics. LÄS MER

  3. 2. Cerebral intraventricular hemorrhage and post-hemorrhagic ventricular dilatation in preterm infants: new mechanistic insights and potential treatment strategies

    Författare :Olga Romantsik; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prematurity; Intraventricular hemorrhage; Post-hemorrhagic ventricular dilatation; White matter injury; Gray matter injury; Preterm rabbits; Extracellular hemoglobin; a-1-microglobulin; animal IVH models; High frequency ultrasound; MRI; corticogenesis;

    Sammanfattning : Intraventricular hemorrhage (IVH) is one of the major co-morbidities of premature birth associated with post-hemorrhagic ventricular dilatation (PHVD) development, long-term neurodevelopmental impairment, behavioral problems, special educational needs, and dependency on social security.Hypothesis and aims: We believe that extravasated blood and further release of extracellular hemoglobin (Hb) are crucial in brain injury following IVH and consequent development of PHVD.

  4. 3. Alpha-1-microglobulin, heme-binding protein, reductase and antioxidant

    Författare :Maria Allhorn; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reduction; inflammation; chronic ulcers; collagen; low density lipoproteins; Medicin människa och djur ; Medicine human and vertebrates ; antioxidation; heme; hemoglobin; alpha-1-microglobulin; lipocalin;

    Sammanfattning : This thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. LÄS MER

  5. 4. Therapeutic opportunities of alpha-1-microglobulin A study in placenta, blood, skin and eye

    Författare :Martin Cederlund; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reactive oxygen species; hemoglobin; myeloperoxidase; oxidative stress; α1-microglobulin;

    Sammanfattning : This thesis describes functional studies of the human protein alpha-1-microglobulin (A1M), with the aim of exploring its usefulness as a therapeutic agent in diseases where oxidative stress is a prominent feature. A1M is a 26 kDa plasma and tissue protein with reductase activity and radical- and heme-binding antioxidative functions. LÄS MER

  7. 5. Preterm intraventricular haemorrhage - Effects of extracellular haemoglobin

    Författare :Snjolaug Sveinsdottir; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Intraventricular haemorrhage (IVH) is the most common brain lesion in preterm infants and is most commonly seen in the sickest children, with 15-20% of very preterm infants developing IVH. The mortality of infants with severe IVH is 20-50 % in the neonatal period and over 50 % of surviving infants develop post-haemorrhagic ventricular dilatation (PHVD) and 40-80 % develop severe neurological impairment, mainly cerebral palsy and mental retardation.
