  1. 1. A radical view of haemoglobin - protein engineering and characterisation

    Författare :Marie Grey; [2009]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; His-Gln tagging; protein purification; blood substitutes; radical scavenging; superoxide dismutase; E. coli; diglobin; Haemoglobin; protein engineering; aqueous two-phase systems; hydrophobic interaction chromatography;

    Sammanfattning : In recent years shortages of donated blood have become a growing problem for health care systems world-wide. Blood substitutes based on human haemoglobin (Hb) could potentially ameliorate this situation. However, clinical trials have indicated problems due to e.g. LÄS MER

  2. 2. Vitreoscilla Haemoglobin - Peroxidase Activity and Metabolic Aspects

    Detta är en avhandling från Tillämpad biokemi, Lunds Universitet

    Författare :Malin Kvist; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; lipid peroxidation; hypoxia; salt stress; Escherichia coli; Lactococcus lactis; hydrogen-bonding network; proximal site; mutations; Vitreoscilla haemoglobin; peroxidase activity; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : The function of non-vertebrate haemoglobins (Hbs) appears more diverse than that of vertebrate Hbs, possibly reflecting the various demands to be met among their hosts. Sharing structural features with other haem proteins/enzymes, Hbs display a qualitative overlap in activities with functions extending beyond oxygen transport/storage. LÄS MER

  3. 3. Vitreoscilla Haemoglobin. Genetic Fusions and Metabolic Characterisation

    Detta är en avhandling från Viktoria Roos, Pure & Applied Biochemistry, Lund University

    Författare :Viktoria Roos; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Metabolism; Biokemi; metabolism; osmotic stress; transcript profiling; DNA microarrays; random elongation mutagenesis; directed evolution; mRNA structure; Vitreoscilla haemoglobin VHb ; Escherichia coli; salt stress.;

    Sammanfattning : Vitreoscilla is an obligate aerobic bacterium living in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla expresses a homodimeric haemoglobin (VHb) when subjected to oxygen-limited conditions. LÄS MER

  4. 4. Blood rheology alterations in cardiovascular disease

    Detta är en avhandling från Department of Cardiology, Clinical sciences, Lund University

    Författare :Carl Gunnar Gustavsson; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kardiovaskulära systemet; Cardiovascular system; erythr; microcirculation; haematocrit; haemoglobin; plasma viscosity; haemorheology; blood viscosity; recurrence; percutaneous transluminal coronary angioplasty; coronary disease; angina pectoris; pulmonary hypertension; Syndrome X; dilated cardiomyopathy;

    Sammanfattning : This thesis deals with the haemorheological aspects of cardiovascular diseases. The resistance of blood to flow is determined by the rheological properties of blood as well as by organic stenoses and regulatory tonus changes in the vessels. LÄS MER

  5. 5. Separation of Glycoproteins using Shielding Boronate Affinity Chromatography

    Detta är en avhandling från Biotechnology, Lund University

    Författare :YuCai Li; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affinity chromatography; boronate; chymotrypsin; haemoglobin; mistletoe lectin; neoglycoprotein; glycosylation; shielding; Biotechnology; Bioteknik; Pharmaceutical and related technologies; Läkemedelsteknik och relaterad teknik;

    Sammanfattning : Glycoproteins, a class of biomolecules, exhibit a variety of biological activities and therefore are of importance in modern biotechnology and pharmaceutical industry. Pure glycoproteins are needed for structural and functional studies. However, the separation of glycoproteins has been a problem until now due to their structural complexity. LÄS MER
