  1. 16. Cell-to-cell communication and virulence in Vibrio anguillarum

    Författare :Kristoffer Lindell; Debra Milton; Karl Klose; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vibrio anguillarum; quorum sensing; stress response; keratocyte; molekylärbiologi; Molecular Biology;

    Sammanfattning : Quorum sensing (QS) is a type of cell-to-cell communication that allows the bacteria to communicate via small molecules to coordinate activities such as growth, biofilm formation, virulence, and stress response as a population. QS depends on the accumulation of signal molecules as the bacterial population increases. LÄS MER

  3. 17. Adaptive Responses by Transcriptional Regulators to small molecules in Prokaryotes : Structural studies of two bacterial one-component signal transduction systems DntR and HpNikR

    Författare :Cyril Dian; Peter Brzezinski; Séan McSweeney; Elisabeth Sauer-Eriksson; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transcription regulator; bacterial biosensor; LysR family; Inducer-binding; nickel-sensing; NikR; signal transduction system; Helicobacter pylori; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Prokaryotes are continually exposed to variations in their environment. Survival in unstable milieu requires a wide range of transcriptional regulators (TRs) that respond to specific environmental and cellular signals by modulating gene expression and provide an appropriate physiological response to external stimuli.

  4. 18. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  5. 19. Tectonic Evolution of the Zagros Suture-and Imbricate Zones in Iraq

    Författare :Maher T. Zainy; Maria Ask; Francisco Gomez; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tectonic evolution; Zagros Fold-and Thrust Belt; Remote sensing; Field feological work; 3D geological modelling; Natural resources exploration; Applied Geology; Tillämpad geologi;

    Sammanfattning : Orogenic belts are expressions of tectonic activity, often host various natural resources (e.g. petroleum and minerals reserves), and influence the society and environment through hazards (e.g. LÄS MER

  7. 20. Insights into dynamic covalent chemistry for bioconjugation applications

    Författare :Shujiang Wang; Oommen Varghese; Nicola Tirelli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dynamic covalent chemistry; reaction mechanism; hydrogel; bioconjugation; catalysis; Kemi med inriktning mot polymerkemi; Chemistry with specialization in Polymer Chemistry;

    Sammanfattning : Dynamic covalent chemistry (DCC) is currently exploited in several areas of biomedical applications such as in drug discovery, sensing, molecular separation, catalysis etc. Hydrazone and oxime chemistry have several advantages, such as mild reaction conditions, selectivity, efficiency, and biocompatibility and therefore, have the potential to be for bioconjugation applications.
