  2. 21. Cyclotides : Tuning Parameters Toward Their Use in Drug Design

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

    Abstract : 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. READ MORE

  4. 22. Molecular Mechanisms of Folding and Binding in PDZ Domains

    Author : Syed Raza ul Haq; per jemth; Daniel Otzen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : PDZ domains are one of the most abundant protein-protein interaction modules that mediate protein recognition by binding to short amino acid sequences in the cells. These globular protein domains usually consist of 80-100 amino acid residues that fold into six ß-strands and two a-helices. READ MORE

  5. 23. Shape Optimization for Acoustic Wave Propagation Problems

    Author : Rajitha Udawalpola; Martin Berggren; Pekka Neittaanmäki; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; shape optimization; design optimization; acoustic wave propagation; Helmholtz equation; Boundary Element Method; Finite Element Method; inverse problems; adjoint method; gradient-based optimization; Scientific Computing; Beräkningsvetenskap;

    Abstract : Boundary shape optimization is a technique to search for an optimal shape by modifying the boundary of a device with a pre-specified topology. We consider boundary shape optimization of acoustic horns in loudspeakers and brass wind instruments. READ MORE

  6. 24. Magnetic fields of cool active stars

    Author : Lisa Rosén; Oleg Kochukhov; Eric Stempels; Andrew Collier Cameron; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stars: magnetic field; stars: late-type; stars: activity; stars: imaging; polarisation; starspots; Astronomy; Astronomi;

    Abstract : Magnetic fields are present throughout the universe and are very important for many astrophysical processes. Magnetic field influences a star throughout its life and affects nearby objects such as planets. READ MORE

  7. 25. Electron-scale physics in space plasma : Thin boundaries and magnetic reconnection

    Author : Cecilia Norgren; Mats André; Jonathan Eastwood; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most of the observable Universe consists of plasma, a kind of ionized gas that interacts with electric and magnetic fields. Large volumes of space are filled with relatively uniform plasmas that convect with the magnetic field. READ MORE
