  2. 1. Directing Angiogenesis : Cellular Responses to Gradients in vitro

    Author : Irmeli Barkefors; Johan Kreuger; Lena Kjellén; Pär Gerwins; Ferdinand Le Noble; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Angiogenesis; Endothelial cell; Cell migration; Chemotaxis; Gradients; Microfluidics; VEGFA; VEGFR2; Exocyst; Exocytosis; Cell and molecular biology; Cell- och molekylärbiologi; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Blood vessels are essential for the delivery of nutrients and oxygen to tissues, as well as for the removal of waste products. Patients with tumors, wounds or diabetes all have active angiogenesis, formation and remodeling of blood vessels, a process that is initiated and manipulated by gradients of secreted signaling proteins.

  4. 2. On the cerebrospinal fluid disposition and neurobiological role of cholecystokinin in man

    Author : Tove Gunnarsson; Conny Nordin; Erik Widerlöv; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Cholecystokinin (CCK) is the most abundant neuropeptide in the brain, where it acts as a neurotransmitter and neuromodulator. The tetrapeptide CCK-4 and the octapeptide CCK-8 have been implicated in various behavioural and physiological functions, such as anxiety, pain and satiety. READ MORE

  5. 3. Structural studies on cytochrome bc1 complex from bovine heart mitochondria

    Author : Momi Iwata; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Ubiquinol:cytochrome c oxidoreductase; membrane protein; X-ray crystallography; Biokemi; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : The cytochrome bc1 complex (Ubiquinol:Cytochrome c oxidoreductase or Complex III) is an enzyme of the mitochondrial respiratory chain, crucial for aerobic metabolism. This enzyme catalyses the electron transfer from membrane-bound ubiquinol to soluble cytochrome c. READ MORE

  6. 4. Non-stationary rotor vibrations due to assymmetric temperature from skew heating in bearings and seals

    Author : Björn Larsson; Patrick Keogh; Linköpings universitet; []
    Keywords : ;

    Abstract : The genesis of this thesis is physical observations of slow alterations of synchronous rotor vibrations over time. It can lead to problems such as difficulties in performing proper balancing and unacceptably high vibration levels. The cause is often asymmetric heating of the rotor shaft. READ MORE
