1. 1. Insulin resistance in children and adolescents : mechanisms and clinical effects

   Författare :Anna E Ek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Insulin resistance is a condition in which insulin does not achieve appropriate response in different target tissues, it is associated with obesity and one of the main culprits in the development of type 2 diabetes. An early sign of disturbed glucose-insulin homeostasis is impaired fasting glucose (IFG) where glucose is elevated in the fasting state. LÄS MER

   Sammanfattning : The transition to a more biobased society introduces both new opportunities and new challenges as we replace nonrenewable materials with renewable alternatives. One important challenge will be to control microbial growth on materials, both to protect the materials from biological degradation and to prevent the spread of infections and toxins that can cause illness.

4. 3. Self-Perceived Health and Nutritional Status among Home-Living Older People : A Prospective Study

   Författare :Yvonne Johansson; Anna-Christina Ek; Margareta Bachrach-Lindström; Tommy Cederholm; Linköpings universitet; []
   Nyckelord :Energy intake; Gender; Health Physical activity; Risk for malnutrition; Symptoms of depression; MEDICINE; MEDICIN;

   Sammanfattning : The overall aim was to follow the development of nutritional status and its significance for general health status using an epiemiologic method in a representative population‐based selection of older individuals in two cohorts. The main focus was to prospectively examine the significance of demographic, social and medical factors and to establish a basis to investigate the possibilities of preventive measures. LÄS MER

5. 4. Estimating source area of pollen and pollen productivity in the cultural landscapes of southern Sweden - developing a palynological tool for quantifying past plant cover

   Författare :Anna Broström; Kvartärgeologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerial photographs; pollen productivity estimates; relevant source area of pollen; southern Sweden; quantitative landscape reconstruction; GIS; pollen dispersal; simulation model; Geology; physical geography; Geologi; fysisk geografi;

   Sammanfattning : Fossil pollen records retrieved from peat and lake sediments have great potential for quantifying past plant cover. This thesis is a contribution to the development of a palynological interpretation tool for reconstructing past cultural landscapes in terms of plant abundance and distribution. LÄS MER
