  1. 21. Electrochemical investigations on lipid cubic phases

    Författare :Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER

  3. 22. Cyclotides : Tuning Parameters Toward Their Use in Drug Design

    Författare :Mariamawit Yonathan Yeshak; Ulf Göransson; Lars Bohlin; Kaleab Asres; Robert Kiss; Uppsala universitet; []
    Nyckelord :cyclotide; Viola abyssinica; Viola odorata; Extraction; Violaceae; vaby; cytotoxic; genotoxic; cell penetrating; microautoradiography; LC-MS; comet assay; cycloviolacin O2; Farmakognosi; Pharmacognosy;

    Sammanfattning : Cyclotides are plant proteins with a unique topology, defined as the cyclic cystine knot motif. The motif endows cyclotides with exceptional chemical and biological stability. They also exhibit a wide range of biological activities including insecticidal, cytotoxic, anti-HIV and antimicrobial effects. LÄS MER

  4. 23. Epitaxial III-V/Si heterojunctions for photonic devices

    Författare :Giriprasanth Omanakuttan; Sebastian Lourdudoss; Yanting Sun; Harri Lipsanen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epitaxy; heterojunction; III-V on Si integration; solar cell; Fysik; Physics;

    Sammanfattning : Monolithic integration of III-V materials on silicon is of great interest for efficient electronic-photonic integrated devices and multijunction solar cells on silicon. However, defect formation in the heteroepitaxial layers due to lattice mismatch, thermal mismatch, and polarity mismatch makes it a great challenge. LÄS MER

  5. 24. Functional Characterization of the Yeast Tumour Suppressor Homologue Sro7p

    Författare :Annabelle Forsmark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Yeast; protein sorting; protein secretion; L 2 GL; tumour suppressor; SRO7; SRO77; ENA1; exocytosis; post-Golgi vesicles; ART5; E3 adaptor; ubiquitylation; ATLGL1; ATLGL2;

    Sammanfattning : Correct targeting of newly synthesized proteins to appropriate domains of the cell membrane is crucial to cellular architecture, polarity and function, making it no surprise that many proteins of the secretory machinery are conserved throughout evolution. This work presents a functional characterisation of the Saccharomyces cerevisiae cell polarity protein and tumour suppressor homologue, Sro7p. LÄS MER

  7. 25. Coiled coil cytoskeleton in cell architecture and osmotic stress response in Streptomyces

    Författare :Katsuya Fuchino; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coiled coil protein; Streptomyces coelicolor; polar growth; osmotic-stress response; turgor;

    Sammanfattning : Coiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. LÄS MER
