  1. 1. Strategies to explore the membrane proteome of a cell

    University dissertation from Stockholm : Department of Analytical Chemistry, Stockholm University

    Author : Gianluca Maddalo; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Membrane proteins; Proteomics; Escherichia coli; Enterococcus faecalis; Synechocystis; Mass Spectrometry; BN SDS-PAGE; FT-ICR-MS; Myelin P2 protein; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Abstract : The cell envelope plays key roles in numerous processes such as maintaining cellular integrity, communication with other cells, signal transduction, maintenance of cellular homeostasis, and regulation of the traffic of molecules between the cell and the extracellular milieu. Essential membrane components in many of these processes are proteins. READ MORE

  2. 2. Investigating a cell replacement therapy in the inner ear

    University dissertation from Stockholm : Karolinska Institutet, Department of Clinical Neuroscience

    Author : Zhengqing Hu; Karolinska Institutet.; Karolinska Institutet.; [2005]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult neural stem cell; Cell therapy; Differentiation; Dorsal root ganglion; Embryonic stem cell; Gene transfer; Hearing loss; Nerve growth factor; Neurogenin; Organ of Corti; Spiral ganglion; Transplantation;

    Abstract : The mammalian auditory system is sensitive to genetic disorders, aging and injuries caused by overstimulation, ototoxic drugs and viral infections. Since the sensory epithelium (the organ of Corti) and the spiral ganglion neurons (SGNs) in adult mammalian do not regenerate spontaneously when they are damaged, a cell substitution strategy was proposed to compensate the function of the degenerated SGNs.

  3. 3. Regeneration of the auditory nerve - a cell transplantation study

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Björn Palmgren; Karolinska Institutet.; Karolinska Institutet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Since in mammals, the hair cells or the spiral ganglion neurons (SGNs) in the inner ear do not regenerate, damage to these cells is an irreversible process. Presently the only aid for patients with severe to profound hearing impairment due to damaged hair cells is a cochlear implant (CI). READ MORE

  4. 4. Biobased Adipic Acid - Challenges in Establishing a Cell Factory

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Science, Intervention and Technology

    Author : Emma Skoog; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 2-hexenedioic acid; enzyme engineering; 6-aminohex-2-enoic acid; S. cerevisiae; adipic acid pathway via lysine; cell factory; C. viswanathii; lignocellulose; biorefinery; tolerance; in silico docking; adipic acid;

    Abstract : Growing concern regarding climate change calls for sustainable solutions to significantly reduce our dependency on non-renewable fossil-based raw materials. One potential solution is the development of biorefineries where biobased, renewable raw materials are converted into valuable products via enzymatic, chemical or microbial conversion. READ MORE

  5. 5. Regulation of intracellular signaling events that modulate insulin action

    University dissertation from Göteborg

    Author : Silvia Gogg; Göteborgs universitet.; Gothenburg University.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; insulin resistance; EGF; Gab 1; insulin receptor substrate; PI3-kinase; Thiazolidinediones; PPARã; insulin signaling; glucose transport; adipose tissue; â-cell.;

    Abstract : Insulin regulates several mechanisms of fundamental importance to the body involving glucose, fat andprotein metabolism. Insulin resistance in skeletal muscle, liver and adipose tissue promotes an increaseddemand for insulin secretion. READ MORE
