  1. 21. Resilience, mental health, and exposure to violence among individuals with former or current experiences of being a refugee in Sweden : quantitative and qualitative studies

    Författare :Erica Mattelin; Laura Korhonen; Amal Khanolkar; Bernadette Nirmal Kumar; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Refugee; Migrant; Mental health; Adversity; Resilience;

    Sammanfattning : Studies indicate that individuals with current or former experiences of being a refugee are more likely to have experienced adverse events, like violence, and face mental health challenges in their host countries. After arrival in host countries, people with refugee experiences often confront various post-migration adversities like discrimination. LÄS MER

  3. 22. Parental Perspectives on Preschool Children’s Lifestyle : quantitative and qualitative aspects

    Författare :Christina Stenhammar; Anna Sarkadi; Birgitta Edlund; Björn Wettergren; Lennart Köhler; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eating habits; lifestyle; childhood overweight; parents; perspectives; physical activity; and postal questionnaire; Paediatric medicine; Pediatrisk medicin; Pediatrik; Pediatrics;

    Sammanfattning : Children’s lifestyle has changed significantly during the recent decades, with an increasing prevalence of obesity as one outcome. Parents are usually the most influential people in young children’s lives. LÄS MER

  4. 23. Methodological aspects of quantitative cardiac molecular imaging

    Författare :Tanja Kero; Mark Lubberink; Håkan Ahlström; Elin Trägårdh; Uppsala universitet; []
    Nyckelord :PET; cardiac amyloidosis; 11C-PIB; retention index; standardized uptake value; PET-MR; MRI; myocardial blood flow; 15O-water; quantification; quantitative modeling;

    Sammanfattning : The objective of this research was to facilitate the use of quantitative cardiac molecular imaging by developing and validating methods and applications. More specifically:we determined the optimal tracer kinetic model for analysis of 11C-PIB and evaluated the performance of two simpler measures, retention index (RI) and standardized uptake value (SUV), in the quantification of cardiac 11C-PIB uptake in amyloidosis.

  5. 24. Quantitative genetic variation in declining plant populations

    Författare :Maarten Ellmer; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Saxifraga granulata; Briza media; Nigella degenii; bottleneck; Inbreeding depression; founder effects; drift; quantitative genetic; diversifying selection; habitat fragmentation; small populations;

    Sammanfattning : The ecological and genetic effects of habitat fragmentation are an issue of major concern in current conservation biology. Habitat fragmentation results in smaller habitat areas and as a consequence smaller and more isolated populations. Many habitats have become fragmented through human activities such as forestry and agricultural development. LÄS MER

  7. 25. Contributions to quantitative dynamic contrast-enhanced MRI

    Författare :Anders Garpebring; Mikael Karlsson; Ronnie Wirestam; Nils Östlund; Jón Hauksson; Steven Sourbron; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic contrast-enhanced MRI; quantitative imaging; parameter estimation; uncertainty estimation; arterial input function; radiofysik; radiation physics;

    Sammanfattning : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. LÄS MER
