  2. 21. In vivo analysis of amino acid permease folding in yeast

    Author : Andreas Ring; Per O. Ljungdahl; George Diallinas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; endoprotease; subcellular fractionation; membrane-localized chaperone; amino acid permease; endoplasmic reticulum; membrane protein folding; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : Plasma membrane (PM) proteins are critical for cells to respond to environmental cues, such as the availability of nutrients. The yeast Saccharomyces cerevisiae is able to sense extracellular amino acids using the SPS sensing system. READ MORE

  4. 22. The tectonic evolution of the western part of the Svecofennian orogen, central Sweden : Insight from U/Pb and 40Ar/39Ar geochronology at Forsmark

    Author : Tobias Hermansson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; Svecofennian orogen; Tectonic models; Tectonic cycles; Uplift; Cooling; Ductile deformation; Geochronology; U Pb; 40Ar 39Ar; Geologi; fysisk geografi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi;

    Abstract : The Forsmark area, in the western part of the Svecofennian orogen, central Sweden, is situated between two major Palaeoproterozoic tectonic domains that show contrasting histories with respect to timing of igneous activity, ductile deformation and metamorphism. At Forsmark, WNW to NW trending, ductile deformation belts anastomose around tectonic lenses with an inferred lower degree of ductile strain. READ MORE

  5. 23. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5

    Author : António Martins; Per O. Ljungdahl; Bruno André; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; regulated proteolysis; endoprotease; serine protease; substrate specificity; subcellular fractionation; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. READ MORE

  6. 24. 40Ar/39Ar, AFT and (U-Th)/He thermochronologic implications for the low-temperature geological evolution in SE Sweden

    Author : Pia Söderlund; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 40Ar-39Ar; Fennoscandian Shield; U-Th He; AFT; geochronology; thermochronology; cooling; uplift;

    Abstract : The Oskarshamn and Forsmark areas in the Fennoscandian Shield, SE Sweden, have been chosen as potential sites for hosting highly radioactive nuclear waste. To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c.

  7. 25. P-T evolotion and High-temperature deformation of Precambrian eclogite, Sveconorwegian orogen

    Author : Lorraine Tual; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Eclogite; Precambrian; P–T path; Basal shear zone; Sveconorwegian orogen; Deformation; thermometry;

    Abstract : The 1.1-0.9 Ga Sveconorwegian orogen is one of several Grenvillian-aged orogenic belts that mark the amalgamation of supercontinent Rodinia. The highest-pressure rocks in the Sveconorwegian orogen are eclogites in the Eastern Segment (SW Sweden). READ MORE
