  2. 1. The control of growth and metabolism in Caenorhabditis elegans

    Author : Josefin Friberg; Simon Tuck; Cathy Savage-Dunn; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TGFβ; insulin; collagen; p70 S6K; metabolism; growth; dauer; Caenorhabditis elegans; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The control of growth is a poorly understood aspect of animal development. This thesis focuses on body size regulation in Caenorhabditis elegans, and in particular, how worms grow to a certain size. In C. elegans, a key regulator of size is the TGFβ homologue DBL-1. READ MORE

  4. 2. The plasticity of aging and survival : a role for the thioredoxin system in Caenorhabditis elegans

    Author : Juan Carlos Fierro-González; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Thioredoxin and related systems regulate many biological processes in diverse species. In mammals, in addition to protecting against oxidative damage, they also play key roles as regulators of transcription factors, signaling cascades and immune responses. READ MORE

  5. 3. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Author : Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Abstract : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. READ MORE

  6. 4. Discovering and targeting the mechanisms that govern age-related decline

    Author : Xin-Xuan Lin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Aging is recognized as a major risk factor for many diseases. Thus, the identification of a means to target aging would bear great potential to improve human health and quality of life. READ MORE

  7. 5. Insulin secretion and ASNA-1-dependent function of the endoplasmic reticulum in C. elegans

    Author : Ola Billing; Gautam Kao; Jussi Jäntti; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell research; cellforskning; genetik; Genetics;

    Abstract : ASNA1 is a well-conserved ATPase involved in a wide range of functions, including cisplatin resistance, growth control, insulin secretion and targeting of tail-anchored (TA) proteins to membranes. It is a positive regulator of insulin secretion both in the roundworm Caenorhabditis elegans and in humans. READ MORE
