  1. 1. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Katharina Bruzelius; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; milk; Natural science; cancer; prolactin; insulin; hydrocortisone; retinoic acid; MAC-T; northern blot; two-dimensional electrophoresis; bovine mammary gland; selenium; selenoprotein;

    Sammanfattning : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. LÄS MER

  2. 2. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Tien Hoac; Lund University.; Lunds universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; Copper; Zinc; Oxidative stability; Thioredoxin reductase; Glutathione peroxidase; Selenoproteins; Milk; Selenium supplementation; Technological sciences; Teknik;

    Sammanfattning : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. LÄS MER

  3. 3. Combinatorial Methodology. Screening for affinity specific ligands to biological and artificial receptors

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Margareta Krook; Lund University.; Lunds universitet.; [1998]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; peptide library; combinatorial; screening; phage display; affinity; DNA-interaction; chymotrypsin; peptide inhibitor; antibody; IgG; Fc; molecular imprinting; steroid; receptor; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik;

    Sammanfattning : Combinatorial screening methodology has been employed to select new affinity specific ligands to bilogical and artificial receptors. The screening methodology, in particular screening of combinatorial phage display peptide libraries against target molecules differing in function and shape, is focused upon. LÄS MER

  4. 4. Beta-Lactamase in Haemophilus ducreyi: Purification, Characterization, and Mutagenesis

    Detta är en avhandling från Pure and Applied Biochemistry, Lund University

    Författare :Ratana Lawung; Lund University.; Lunds universitet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biokemi; Metabolism; Biochemistry; enzyme calorimeter; site-directed mutagenesis; ampicillin resistance plasmid; Haemophilus ducreyi; TEM-1 b-lactamase; metabolism; Proteins; enzymology; Proteiner; enzymologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Sammanfattning : Chancroid caused by Haemophilus ducreyi, has been described as a significantly predisposing factor of HIV heterosexual transmission in an endemic region of both diseases. Antibiotic resistances are extensively found in H. ducreyi and many of the resistances are due to the presence of resistance plasmids. LÄS MER

  5. 5. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance
