  2. 1. A Few Strokes to the Family Portrait of Translational GTPases

    Author : Vasili Hauryliuk; Måns Ehrenberg; Richard Buckingham; Uppsala universitet; []
    Keywords : Molecular biology; translation; GTPase; EF-G; eRF3; Molekylärbiologi;

    Abstract : Protein biosynthesis is a core process in all living organisms. Assembly of the protein chain from aminoacids is catalysed by the ribosome, ancient and extremely complex macromolecular machine. READ MORE

  4. 2. Characterization of Si-based heterostructures prepared by MBE and containing Ge, C, or Er

    Author : Kenneth B. Joelsson; Karl Eberl; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Silicon molecular beam epitaxy (MBE) has been used to prepare various Si-based structures.The first part of the work concerns hole transport in Si1-xGex layers for Ge contents 0≤x≤0.36 and B-doping concentrations 2-7.5x1018 cm-3. READ MORE

  5. 3. Accuracy of protein synthesis and its tuning by mRNA modifications

    Author : Gabriele Indrisiunaite; Måns Ehrenberg; Suparna Sanyal; Jaanus Remme; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribosome; Protein synthesis; Translation; Accuracy; Release factor; Termination; mRNA modifications; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : The ribosome is a large macromolecular complex that synthesizes all proteins in the cell in all kingdoms of life. Proteins perform many vital functions, ranging from catalysis of biochemical reactions to muscle movement. It is essential for cells and organisms that proteins are synthesized rapidly and accurately. READ MORE

  6. 4. Pharmacological targeting of nonsense mutant TP53 and PTEN in cancer

    Author : Angelos Heldin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The TP53 tumor suppressor gene encodes p53 and is inactivated by mutations in around half of all human tumors. Approximately 11% of TP53 mutations are nonsense mutations, resulting in the premature termination of translation and the production of truncated and non-functional p53 proteins. READ MORE

  7. 5. Studies of Light Emitting Devices Based on Er-doped Si and SiGe Layered Structures

    Author : Chun-Xia Du; Fransesco Priolo; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electroluminescence; diode; transistor; hot electron; recombination; excitation; de-excitation; Auger effect; molecular beam epitaxy; Er; Si; SiGe;

    Abstract : Doping with rare earth element erbium (Er) in Si has recently attracted a lot of research interest due to potential applications in Si-based opto-electronics. By using molecular beam epitaxy (MBE), precipitate-free Er-doping in Si has been made together with other co-dopants, e.g., oxygen (0) and fluorine (F), up to a level ∼1020 cm-3. READ MORE
