  1. 1. Peptic ulcer disease in an adult population : the Kalixanda study – a population-based endoscopic study

    Författare :Pertti Aro; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Epidemiology; esophagogastroduodenoscopy EGD ; peptic ulcer disease PUD ; population-based.;

    Sammanfattning : Introduction: The pattern of symptoms and perception of disease among patients seeking care does, due to health care seeking behaviour, most probably not reflect the true health status in the general population. Upper esophagogastroduodenoscopy (EGD) is considered to be gold standard for upper gastrointestinal (GI) disease assessment, but is seldom used in epidemiological studies. LÄS MER

  3. 2. Organofluorine Mass Balance and Per- and Polyfluoroalkyl Substance Analysis of Environmental Samples and Human Blood

    Författare :Rudolf Aro; Leo W. Y. Yeung; Anna Kärrman; Ulrika Eriksson; Christopher Higgins; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; organofluorine mass balance; PFAS; extractable organofluorine; unidentified organofluorine; whole blood; surface water; effluent; sludge;

    Sammanfattning : Per- and polyfluoroalkyl substances (PFAS) have been linked to a range of negative health and environmental effects. Regulations limiting and/or banning the use of some of the legacy compounds have been introduced. Consequently, the production and use of PFAS has diversified. LÄS MER

  5. 4. Pathogenic Neisseria infections of human neutrophils and epithelial cells : focusing on host responses and immune evasion

    Författare :Niklas Söderholm; Helena Aro; Thomas Rudel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neisseria meningitidis; Neisseria gonorrhoeae; Neutrophils; PMN; Epithelial cells; Polarized cells; Type IV pili; Adherence; Cell cycle; DNA damage; Lactobacillus; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : N. meningitidis and N. gonorrhoeae are obligate human pathogens that colonize mucosal surfaces and are often carried asymptomatically. These bacteria have developed adhesive structures that promote adherence to host cells and efficient colonization of new hosts. LÄS MER

  7. 5. Chronic stress among adolescents : Contributing factors and associations with academic achievement

    Författare :Karin Schraml; Aleksander Perski; Katariina Salmela-Aro; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Chronic stress; adolescents; academic achievement; sleep; social jetlag; self-esteem; demand-control-support; gender; Psychology; psykologi;

    Sammanfattning : According to recent nationwide surveys there have been dramatic increases in stress and serious stress-related health problems among Swedish adolescents. The aims of the present thesis were to investigate the prevalence of perceived chronic stress among sixteen-year-old adolescents who attended their first year at high-ranking high schools in the Stockholm area, to examine if factors that have been found to be relevant in the development of chronic stress among adults also contribute to chronic stress among adolescents, and to investigate the associations between chronic stress and sleep-related variables and academic achievement.
