  1. 1. New directions in non-porous membrane extraction

    Författare :Eddie Thordarson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extracting syringe; solvent-free; miniaturisation; micro-porous membrane liquid-liquid extraction; polymeric membrane extraction; Non-porous membrane extraction; supported liquid extraction; integration; automation; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Complex biological and environmental samples require a high degree of selectivity in order to determine components therein. Sensitivity measures, such as analyte pre-concentration are often required for assessing composition quantitatively. LÄS MER

  3. 2. Dynamics of peptide chains during co-translational translocation, membrane integration & domain folding

    Författare :Rickard Hedman; Gunnar von Heijne; Daniel N. Wilson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; membrane integration; translocation; folding; arrest peptide; SecM; Biochemistry; biokemi;

    Sammanfattning : The biosynthesis of proteins occurs at the ribosomes, where amino acids are linked together into linear chains. Nascent protein chains may undergo several different processes during their synthesis. Some proteins begin to fold, while others interact with chaperones, targeting factors or processing enzymes.

  4. 3. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

    Författare :Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

    Sammanfattning : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. LÄS MER

  5. 4. Integration and topology of membrane proteins

    Författare :Carolina Boekel; Gunnar von Heijne; IngMarie Nilsson; Stephen High; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; insertion; Sec61; translocation; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Membrane proteins comprise around 20-30% of most proteomes. They play important roles in most biochemical pathways. All receptors and ion channels are membrane proteins, which make them attractive targets for drug design. Membrane proteins insert and fold co-translationally into the endoplasmic reticular membrane of eukaryotic cells. LÄS MER

  7. 5. Integration of Aqueous Two-Phase Systems into Recovery Processes for Biomolecules

    Författare :Cecilia Kepka; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Proteins; proteins; plasmid DNA; large-scale; protein purification; integration; Expression; aqueous two-phase systems; enzymology; Proteiner; enzymologi;

    Sammanfattning : The main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. LÄS MER
