  1. 21. Chloride Channels and Brown Fat Cells

    Författare :Victor Sabanov; Jan Nedergaard; Bernd Nilius; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chloride channel; BAPTA; EGTA; Ca; Animal physiology; Zoofysiologi;

    Sammanfattning : Chloride ion channels are macromolecular pores providing for passage of chloride ions (and certain other inorganic and organic anions) through the cell membrane, down their electrochemical gradients. Chloride channels are differentially expressed in various cells, to best suit specific cellular activities. LÄS MER

  3. 22. Gene regulation, intracellular signaling and membrane traffic : studies in primary human skeletal muscle cultures

    Författare :Lubna Al-Khalili; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Skeletal muscle cultures; insulin signal transduction; glucose transport; GLUT4; RNAi; Na ; K -ATPase; MEF2;

    Sammanfattning : Skeletal muscle is an insulin sensitive organ and plays a major role in whole body electrolyte and substrate homeostasis in the post prandial state. Impaired insulin action in skeletal muscle may lead to the pathological condition of insulin resistance. LÄS MER

  4. 23. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae

    Författare :Mridula Muppavarapu; Tracy Nissan; Per Sunnerhagen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA decapping; mRNA degradation; Pat1; Edc3; Lsm4; Lsm1-7; P bodies; Dcp2; Transcription; Ribosome biogenesis; Exosome.; molekylärbiologi; Molecular Biology;

    Sammanfattning : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. LÄS MER

  5. 24. Painfully Energetic : A tale of two proteins potentially connected

    Författare :Eva Sperling; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Complex I; Mrp-antiporter; Membrane bound hydrogenases; TRP ion channels; TRPA1; thermosensation; chemosensation; 23Na-NMR;

    Sammanfattning : NADH:quinone oxidoreductase (Complex I) is the first enzyme of the respiratory chain and is involved in energy conservation generating an electro-chemical gradient across a membrane. The enzyme can be divided into a membrane spanning domain and a hydrophilic domain, which protrudes from the membrane. LÄS MER

  7. 25. Ethanol production from lignocellulose using high local cell density yeast cultures. Investigations of flocculating and encapsulated Saccharomyces cerevisiae

    Författare :Johan Westman; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; yeast; encapsulation; lignocellulose; ethanol; fermentation; flocculation; inhibitors; tolerance; xylose; co-utilisation; Resource Recovery; Resursåtervinning; Resource Recovery;

    Sammanfattning : Efforts are made to change from 1st to 2nd generation bioethanol production, using lignocellulosics as raw materials rather than using raw materials that alternatively can be used as food sources. An issue with lignocellulosics is that a harsh pretreatment step is required in the process of converting them into fermentable sugars. LÄS MER
