  1. 1. Pathogen entry mechanisms and endocytic responses to plasma membrane damage

    Author : Lars Nygård Skalman; Richard Lundmark; Kristian Riesbeck; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; Endocytosis; plasma membrane; pathogens; virus; bacterial membrane vesicles; Helicobacter pylori; adenovirus 37; listeriolysin O; pore-forming toxins; membrane repair;

    Abstract : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. READ MORE

  2. 2. Nucleotide-binding Proteins in the Plant Thylakoid Membrane

    Author : Sophie Heurtel Thuswaldner; Cornelia Spetea Wiklund; Bengt Persson; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; plant; Arabidopsis; photosynthesis; thylakoid membrane; nucleotide-binding; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : Life on Earth is dependent on the oxygen produced through photosynthesis. The thylakoid membrane is the site for the light-driven reactions of photosynthesis, which oxidize water and supply energy in the form of ATP, mainly for carbon fixation. The utilization of ATP in the lumenal space of the thylakoid has not been considered in the past. READ MORE

  3. 3. Survival of onlay bone grafts. A study in the adult rat

    Author : Monica Gordh; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rats; polytetrafluoroethylene; artificial; membrane; immunohistochemistry; cortical perforations; bone morphogenetic protein; bone marrow; bone; bone grafts; Odontologi; stomatology; Odontology; skull; tibia;

    Abstract : The aim of this thesis was to study onlay bone grafting in the adult rat to improve graft incorporation and perservation of graft size. In 167 adult isogeneic lewis rats, the size maintenance and bone formation at the graft-host interface of uni- and bicortical onlays positioned in various environments and treatments were investigated.

  4. 4. On the lateral organisation of the thylakoid membrane

    Author : Ravi Danielsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thylakoid membrane heterogeneity; Plant biochemistry; Växtbiokemi; Thylakoid structure; Phase partition; Thylakoid fractions;

    Abstract : In this work the lateral heterogeneity of the thylakoid membrane was investigated by quantifying the amount of photosystem I (PSI), photosystem II (PSII) and some PSII complexes and PSII proteins in different domains of the thylakoid. Grana, grana core, grana margins and stroma lamellae + end fractions were obtained by sonication and separation in a non-detergent, aqueous polymer two-phase system. READ MORE

  5. 5. Healing of tympanic membrane perforations - an experimental study

    Author : Anisur Rahman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Embryonic stem cells; Healing; Immunosuppressive; Laser; Mesenchymal stem cells; Moiré interferometry; Myringotomy; Perforation; Tympanic membrane;

    Abstract : Most acute tympanic membrane perforations heal spontaneously without any residual complication, whereas a fraction transforms into a chronic perforation. The current treatment of a chronic perforation is surgical repair, which is a costly, time consuming and uncomfortable procedure particularly for the pediatric patients. READ MORE
