  1. 1. Stress in chickens : Effects of domestication and early experience on behaviour and welfare

    Author : Maria Ericsson; Per Jensen; Linda Keeling; Bjarne Braastad; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.

  2. 2. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

    Author : Pushan Bag; Stefan Jansson; Fransis Andre Wollman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scots Pine; Norway spruce; Photosynthesis; Winter adaptation; biologisk kemi; biological chemistry; biology; biologi; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik;

    Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

  3. 3. A systems biology understanding of protein constraints in the metabolism of budding yeasts

    Author : Iván Domenzain Del Castillo Cerecer; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene regulation; omics analysis; enzyme capacity; metabolism; systems biology; stress adaptation; genome-scale modeling; metabolic engineering;

    Abstract : Fermentation technologies, such as bread making and production of alcoholic beverages, have been crucial for development of humanity throughout history. Saccharomyces cerevisiae provides a natural platform for this, due to its capability to transform sugars into ethanol. READ MORE

  4. 4. Domestication Effects on the Stress Response in Chickens : Genetics, Physiology, and Behaviour

    Author : Amir Fallahshahroudi; Per Jensen; Frank Albert; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Animal domestication; stress response; gene expression; QTL; eQTL;

    Abstract : Animal domestication, the process where animals become adapted to living in proximity to humans, is associated with the alteration of multiple traits, including decreased fearfulness and stress response. With an estimated population of 50 billion, the domesticated chicken is the most populous avian species in the world. READ MORE

  5. 5. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    Author : Virginia Claudio; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Abstract : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.
