  2. 1. The Histidine-rich Glycoprotein in Reproduction

    Author : Karin E Lindgren; Inger Sundström-Poromaa; Helena Åkerud; Eva Wiberg-Itzel; Lalit Kumar Parameswaran Grace; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; embryo culture medium; embryogenesis; embryonic secretome; endometrium; histidine-rich glycoprotein; human embryo development; human embryo implantation; human endometrial endothelial cells; in vitro fertilisation; infertility; male infertility; proximity extension assay; recurrent miscarriage; single nucleotide polymorphism; sperm quality; time-lapse technique; vascular endothelial growth factor;

    Abstract : Infertility affects 15% of reproductive-aged couples. The milieu surrounding the growing embryo is of outmost importance, and should be optimised during in vitro fertilisation (IVF). Many biological processes, such as angiogenesis, coagulation, and immune processes need to be well regulated for a pregnancy to occur and progress normally. READ MORE

  4. 2. Violaxanthin De-epoxidase and the Xanthophyll Cycle

    Author : Anna Gisselsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; zeaxanthin.; xanthophyll cycle; violaxanthin de-epoxidse; thylakoid; regulation; quenching; protonation; pH-dependence; light stress; histidine; Conformational change; domains; Växtbiokemi;

    Abstract : The xanthophyll cycle is a mechanism for short term adaptation of plants to varying light intensities. It involves a reversible conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin, upon high light intensities. READ MORE

  5. 3. Xanthophyll Cycle in the Light of Thylakoid Membrane Lipids - Membrane Packing, Curvature Elastic Stress and Enzyme Binding

    Author : Anna Szilagyi; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; steroider; Lipids; steroids; membranes; Lipider; enzymologi; HPLC; laurdan; fluorescence spectroscopy; Proteins; enzymology; Proteiner; curvature elastic stress; enzyme binding; thylakoid membrane; membrane fluidity; lipid packing; histidine; VDE; zeaxanthin; xanthophyll cycle; mebran;

    Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. The enzyme, violaxanthin de-epoxidase (VDE) catalyses the conversion of violaxanthin to zeaxanthin, via the intermediate antheraxanthin. VDE is a membrane-hosted enzyme during its activity.

  7. 5. ANTIMICROBIAL ACTIVITIES OF HISTIDINE-RICH GLYCOPROTEIN AND CATIONIC PEPTIDES

    Author : Victoria Rydengård; Lund Dermatologi och venereologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dermatologi; venereologi; venereology; Dermatology; histidine-rich glycoprotein; heparin-binding; zinc; low pH; Medicine human and vertebrates ; Medicin människa och djur ; innate immunity; antimicrobial;

    Abstract : In an environment full of potential pathogens it is of importance for organisms to mount a fast and effective defence. Antimicrobial peptides are ancient and integral effector molecules of the innate immune system. They are found in all kinds of species from bacteria to plants and animals, indicating their importance during evolution. READ MORE
