  1. 6. Interorganellar connectivity : From protein to lipid homeostasis

    Författare :Carlotta Peselj; Sabrina Büttner; Tim Levine; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Interorganellar connectivity; nucleus; NVJs; chronic lipid bilayer stress; glucose and phosphate exhaustion; nutritional regimes; transmembrane chaperone; IPTP; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Interorganellar connectivity is fundamental for the maintenance of organellar and cellular functionality and viability. This is achieved and maintained by a complex network of signaling cascades, vesicle trafficking between organelles as well as by establishment of direct physical contact at membrane contact sites (MCS).

  3. 7. Diet, lifestyle, antioxidants, and biomarkers of cancer risk - an epidemiological report from the Malmö Diet and Cancer cohort

    Författare :Peter Wallström; Nutritionsepidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Public health; epidemiology; Folkhälsa; epidemiologi; cancerology; Cytologi; oncology; Cytology; Alcohol; Obesity; Smoking; Autoantibodies; Glutathione S-transferase; Oxidative stress; Vitamin E; Carotene; Body composition; Vegetables; Fruits; Cross-sectional; Adult; Diet surveys;

    Sammanfattning : This thesis examines associations between a number of epidemiological or biological markers of cancer risk and oxidative stress, in order to achieve a better understanding of how diet, lifestyle, and genetic factors contribute to the occurrence of oxidative stress. Data from the Malmö Diet and Cancer (MDC) cohort was used. LÄS MER

  4. 8. Osmoregulation at different stages of the yeast life cycle

    Författare :Cecilia Geijer; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stress signalling; osmoregulation; aquaporins; cerevisiae; germination; germination;

    Sammanfattning : The ability to adapt to changing and potentially harmful conditions in the surrounding environment is crucial for fitness and survival of all living cells; in particular unicellular organisms, since they are frequently exposed to stress factors such as heat, drought, nutritional starvation and toxic substances. The aim of this thesis is to determine how cells respond to osmotic and nutritional changes in the environment and how downstream targets of signalling cascades are regulated. LÄS MER

  5. 9. Microstructure and rheological properties of plant particle suspensions prepared using different physical treatments

    Författare :Patricia Lopez-Sanchez; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; yield stress; rheology; elastic modulus; cell wall; tomato; broccoli; plant particle suspension; microstructure; carrot;

    Sammanfattning : Suspensions of plant particles are very common products or by-products in many industries such as food, paper and biofuel. An improved understanding of the complex relationship between microstructure and rheology of these plant systems might help design, control and predict their structural and material properties.

  7. 10. Tachykinin-related peptide signaling and its role in metabolic stress in Drosophila

    Författare :Ryan Tyge Birse; Dick Nässel; Micheal Pankrantz; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurobiology; Neurobiologi;

    Sammanfattning : Tachykinins (TKs) constitute a highly conserved family of multifunctional neuropeptides that are known to be involved in a multitude of functions in mammals. Peptides that are presumed ancestrally related to tachykinins, so called Tachykinin-related peptides (TKRP) have been identified in invertebrates. LÄS MER
