2. 1. T-Cell Protein Tyrosine Phosphatase, a Regulator of the PDGF Signaling Pathway

   Author : Susann Karlsson; Carina Hellberg; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; TC-PTP; receptor trafficking; PK-M2; Medical cell biology; Medicinsk cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

   Abstract : Platelet-derived growth factor (PDGF) is a potent stimulator of cell growth, survival and motility. PDGF exerts its function by binding to specific tyrosine kinase receptors, initiating receptor auotphosphorylation and initiation of specific signaling pathways that regulates the cellular response.

4. 2. Membrane-remodeling by SNX18 in endosomal transport and autophagy

   Author : Karin Håberg; Sven Carlsson; Geir Bjørkøy; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sorting nexin; SNX9-family; SNX18; endosomal transport; autophagy; medicinsk biokemi; Medical Biochemistry;

   Abstract : The intracellular space of eukaryotic cells is subdivided into functionally distinct membrane-enclosed organelles. Regulation of these intracellular membranes requires an intricate network of specialized lipids and proteins that maintain organellar integrity and mediate transport between organelles. READ MORE

5. 3. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

   Author : Tarek Dishisha; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Abstract : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. READ MORE

6. 4. Recycling of CIGS solar cell waste materials

   Author : Anna Gustafsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrometallurgy; Pyrometallurgy; CIGS; Recycling; Solar cells;

   Abstract : The increased interest in solar power over the last few decades has led to a constant development of existing and new types of solar cells. One type of solar cell that is making advances on the global market is copper indium gallium diselenide (CIGS) thin film solar cells. READ MORE

7. 5. REGULATED UPTAKE OF BIOPOLYMERS Role of cell surface proteoglycans Implications for drug and gene delivery

   Author : Staffan Sandgren; Bröstcancer-genetik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin människa och djur ; Cytology; oncology; proliferation; differentiation; Medicine human and vertebrates ; growth factor; cancer; drug delivery; gene therapy; LL-37; HIV-Tat; cell penetrating peptides; polyamines; heparan sulfate; onkologi; Cytologi; cancerology; internalization; proteoglycans;

   Abstract : Cells continuously export, import, and recycle molecules over the plasma membrane. Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes.
