  1. 1. Early obesity : family-based risk factors and treatment interventions

    Författare :Anna Erika Ek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Sammanfattning : Background The high prevalence of preschool obesity is a global concern. In order to support families through obesity interventions, we need a better understanding of underlying family-based risk factors. Specifically, there is a gap in the knowledge related to challenges that families face in everyday life. LÄS MER

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

    Författare :Anna E. Ek; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    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. 4. Water purification using polyelectrolyte modified cellulose fibers and filters to adsorb bacteria

    Författare :Anna Ottenhall; Monica Ek; Joydeep Dutta; Emma Strömberg; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bacterial adsorption; cellulose filter; Layer-by-Layer; water treatment; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Clean water is necessary for human survival and there is a need for development of cheap and easy water purification techniques to use in emergency situations when there is no access to safe drinking water. Bacteria contaminated water can cause lethal diarrheal diseases and is globally the second most common cause of death among children less than five years of age. LÄS MER

  5. 5. Preventing pressure ulcers by assessment of the microcirculation in tissue exposed to pressure

    Författare :Sara Bergstrand; Margareta Lindgren; Anna-Christina Ek; Maria Engström; Lars-Göran Lindberg; Fredrik Huss; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pressure ulcer; photoplethysmography; laser Doppler flowmetry; non-invasive; tissue blood flow; reactive hyperemia; pressure-induced vasodilation; interface pressure; risk assessment;

    Sammanfattning : The overall aim of this thesis was to combine optical methods into a system with the ability to simultaneously measure blood flow changes at different tissue depths. The goal of such a system was to reveal vascular mechanisms relevant to pressure ulcer etiology under clinically relevant conditions and in relation to the evaluation of pressure-redistribution support surfaces.
