  1. 1. Protein targeting, translocation and insertion in Escherichia coli : Proteomic analysis of substrate-pathway relationships

    Författare :Louise Baars; Jan-Willem de Gier; Jan-Maarten van Dijl; Stockholms universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; protein biogenesis; targeting; translocation; insertion; SecB; SecE; E. coli; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Approximately 10% of the open reading frames in the genome of the Gram-negative bacterium E. coli encodes secretory proteins, and 20% encodes integral inner membrane proteins (IMPs). LÄS MER

  2. 2. Lithium-ion insertion in a V6O13 cathode

    Författare :Örjan Bergström; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Chemistry; cathode material; vanadium oxide; lithium insertion; in situ X-ray diffraction; deformation electron density refinement; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : The transition metal oxide V6O13 is a promising cathode material for high-capacity lithium-polymer batteries in conjunction with a lithium-metal anode. The electro-chemical behaviour of V6O13 has its origin in the ability of the vanadium ions to change their-oxidation states, combined with the open nature of its crystal structure which allows lithium ions to diffuse through it.

  3. 3. The Entheses of the Medial Meniscns and Ligaments of the Knee Joint : Descriptive and Experimental Studies

    Författare :Jizong Gao; Michael Benjamin; Linköpings universitet; []
    Nyckelord :knee joint; meniscus; ligaments; insertion; enthesis; quantitative morphology; fibrocartilage; cement line; collagens; proteoglycans; nerve fibres; tensile strength; failure mode; transection; refixation; repair; healing; osteoarthrosis; histology; immunohistochemistry; biomechanics; rabbit model; MEDICINE; MEDICIN;

    Sammanfattning : Meniscal injuries are common in sports. Surgical removal of the meniscus to relieve symptoms is associated with a high risk for late knee joint osteoarthrosis and pain. Meniscal repair or replacement has therefore been advocated. LÄS MER

  4. 4. Integration and topology of membrane proteins

    Författare :Carolina Boekel; Gunnar von Heijne; IngMarie Nilsson; Stephen High; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; insertion; Sec61; translocation; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Membrane proteins comprise around 20-30% of most proteomes. They play important roles in most biochemical pathways. All receptors and ion channels are membrane proteins, which make them attractive targets for drug design. Membrane proteins insert and fold co-translationally into the endoplasmic reticular membrane of eukaryotic cells. LÄS MER

  5. 5. The Challenge of Probing Lithium Insertion Mechanisms in Cathode Materials

    Författare :Jonas Höwing; Torbjörn Gustafsson; Christian Masquelier; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Li-ion battery; cathode materials; insertion mechanism; single-crystal X-ray diffraction; vanadium oxide; lithium iron phosphate; Oorganisk kemi; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : The Li-ion battery has, from its commercialisation in the early 1990's, now become the most widely used power source for portable low-power electronics: laptops, cellular phones and MP3-players are a few examples. To further develop existing and find new electrode materials for these batteries, it is vital to understand the lithium insertion/extraction mechanisms taking place during battery operation. LÄS MER
