  1. 1. Soil moisture conditions control nutrient accumulation, carbon storage and tree growth in boreal forest landscapes

    Författare :Johannes Larson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Forest and soil properties change across landscapes due to the complex interactions between various environmental factors. In many landscapes, topography exerts a major influence on the variation in soil moisture conditions, which in turn largely affects soil properties and processes. LÄS MER

  3. 2. Unlocking the Role Of Orphan Solute Carrier SLC38A10 In Brain Metabolism : The SLC38A10 transporter in nutrient and metabolic regulation

    Författare :Rekha Tripathi; Robert Fredriksson; Manuel Palacín; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Solute carrier; SLC38A10 transporter; SLC38 family; ER Golgi localization; Amino acid starvation; Nutrient sensing; mTOR signaling; Transcriptomic; Protein array; Metabolomics; Ingenuity Pathway Analysis; Farmaceutisk vetenskap; Pharmaceutical Science; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Membrane transporters are the primary gatekeepers of cells and regulate the transport of nutrients, metabolites, ions, water, and neurotransmitters into and across the human cells. The solute carrier transporters (SLCs) are the most prominent transporters, comprising 430 members divided into 65 subfamilies. LÄS MER

  4. 3. Nutrient and energy sensing in skeletal muscle

    Författare :Atul S Deshmukh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Skeletal muscle; AMPK; mTOR; glucose metabolism; exercise; Akt; TBC1D1 D4; CaMK; NO-cGMP;

    Sammanfattning : Nutrient overload and physical inactivity often leads to the development of obesity and type 2 diabetes. Acute over-nutrition can induce insulin resistance, while physical exercise enhances skeletal muscle insulin sensitivity. Like every living cell, skeletal muscle senses nutrient and energy signals and to adjust metabolic flux. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Remote sensing in optically complex waters : water quality assessment using MERIS data

    Författare :José M. Beltrán-Abaunza; Susanne Kratzer; Carsten Brockmann; Samantha Lavender; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ocean Colour; MERIS; Baltic Sea; Bio-optics; water quality; Chlorophyll; Turbidity; SPM; Himmerfjärden; Remote Sensing; Marine Ecology; marin ekologi;

    Sammanfattning : This PhD study focusses on the use of MEdium Resolution Imaging Spectrometer (MERIS) data for reliable and quantitative water-quality assessment of optically-complex waters (lake, brackish and coastal waters). The thesis is divided into two parts: A. LÄS MER
