  1. 1. Cell models for evaluation of adult and developmental neurotoxicity : Focus on acrylamide

    Författare :Kristina Attoff; Anna Forsby; Åsa Fex-Svenningsen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : This thesis is aimed at summarizing some of the alternative in vitro methods and models that have been used to study both adult and developmental neurotoxicity (DNT), and also to pinpoint some of the important aspects of using alternative in vitro methods. The aim of the papers included in this thesis was to challenge the hypothesis that neurotoxicity and DNT of chemicals can be studied using robust endpoints for proliferation and neural differentiation, such as neurite outgrowth, mRNA expression and protein expression, in two different cell lines.

  3. 2. Nutritional Limitations of a Green Protein Shift with Focus on Iron

    Författare :Cecilia Mayer Labba; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; phytate; non-heme iron absorption; antinutrients; protein shift; protein extract; meat substitutes; plant-based; fava bean; zinc bioavailability; iron bioavailability; sustainable nutrition;

    Sammanfattning : A dietary shift into plant-based diets (PBD) to reduce the climate footprint is advocated. Effects on nutrition and health from a modern PBD, composed of replacement products based on protein extracts are however currently unknown. LÄS MER

  4. 3. Separation of Water and Fat Signal in Magnetic Resonance Imaging : Advances in Methods Based on Chemical Shift

    Författare :Johan Berglund; Joel Kullberg; Lars Johansson; Håkan Ahlström; Zhi-Pei Liang; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Magnetic resonance imaging; digital image reconstruction; chemical shift imaging; water and fat separation; Dixon method; fat suppression; quantitative MRI; whole-body MRI; fatty acid composition; fat unsaturation; triglycerides; adipose tissue; liver fat; T2* mapping; Radiology; Radiologi; Radiology; Radiologi;

    Sammanfattning : Magnetic resonance imaging (MRI) is one of the most important diagnostic tools of modern healthcare. The signal in medical MRI predominantly originates from water and fat molecules. LÄS MER

  5. 4. Local Immune regulation in human pregnancy : with focus on decidual macrophages

    Författare :Charlotte Gustafsson Lidström; Christina Ekerfelt; Eva Sverremark-Ekström; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; placenta; leukocyte; ELISPOT; Clinical immunology; Klinisk immunologi;

    Sammanfattning : During pregnancy, the woman carries a fetus partly foreign to her immune system, because of the expression of paternal antigens. Despite this, the fetus is normally tolerated and not rejected, as is often the case with organs in allogeneic transplantations. LÄS MER

  7. 5. Breakdown situations in dialogues between humans and socially intelligent agents

    Författare :Maitreyee Tewari; Helena Lindgren; Kai-Florian Richter; Olov Engwall; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Dialogues; Breakdown Situations; Focus Shift; Human-Centric Artificial Intelligence; Engeström’s Activity Triangle; We-Intention; Argumentation-Based Dialogues; Grice’s Cooperative Principle; Communicative Functions; Wizard-of-Oz; User Studies; Thematic Analysis; Sequence Organisation; Computer Science; datalogi;

    Sammanfattning : Dialogues between humans are complex due to the challenges in predicting how they will unfold as people may want to achieve different purposes. For instance, to act together, they co-create a common goal; to learn, they co-create knowledge; to build relationships, they share emotions and beliefs. LÄS MER
