  1. 1. Glacial dynamics and till genesis in hilly terrain : A study in the Tallträsk area, central-northern Sweden

    Författare :Hans Ivarsson; Mats Jansson; Per Möller; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; till analyses; glacial stratigraphy; subglacial deposition; deglaciation; hilly terrain; northern Sweden; Physical geography; Naturgeografi;

    Sammanfattning : This study deals with the influence of topography on glacial dynamics and the genesis of till in an area of moder-ate bedrock relief. An area 25 km west of Lycksele, northern Sweden, was investigated using geomorphological and sedimentological methods. LÄS MER

  3. 2. Regulation of fibroblast activity by keratinocytes, TGF-β and IL-1α : studies in two- and three dimensional in vitro models

    Författare :Anita Koskela von Sydow; Mikael Ivarsson; Torbjörn Bengtsson; Hans Törmä; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fibroblast; Keratinocyte; TGF-β; IL-1α; coculture; fibrosis CTGF CNN 2; dermal; organotypic culture;

    Sammanfattning : Dysregulated wound healing is commonly associated with excessive fibrosis. Connective tissue growth factor (CTGF/CCN2) is characteristically overexpressed in fibrotic diseases and stimulated by transforming growth factor-β (TGF-β) in dermal fibroblasts. Reepithelialisation and epidermal wound coverage counteract excessive scar formation. LÄS MER

  4. 3. In vitro Studies of Genodermatoses Affecting Cytoskeletal Integrity and Lipid Processing in Human Epidermis : Pathogenic Mechanisms and Effects of Retinoid Therapy

    Författare :Hao Li; Hans Törmä; Anders Vahlquist; Mikael Ivarsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital Ichthyosiform Erythroderma; Epidermolytic Hyperkeratosis; Ceramides; Keratins; Retinoids; Molecular Probe Techniques; Transglutaminases; Lipoxygenases; Fatty Acid Transporter Proteins; Keratinocytes; Epidermis; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Autosomal dominant epidermolytic ichthyosis (EI) is a rare disease characterized by intra-epidermal blistering due to mutations in either of two keratin genes, KRT1 and KRT10, expressed by suprabasal keratinocytes. Autosomal recessive congenital ichthyosis (ARCI) is a non-blistering, hyperkeratotic disease caused by mutations in one of the following genes: ABCA12, ALOX12B, ALOXE3, TGM1, CYP4F22, NIPAL4 and SLC27A4, which are all essential for skin barrier homeostasis.

  5. 4. Towards explaining the Swedish epidemic of celiac disease : an epidemiological approach

    Författare :Anna Myléus; Anneli Ivarsson; Stig Wall; Hans Stenlund; Stefano Guandalini; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; celiac disease; epidemiology; etiology; infant feeding; infections; prevalence; screening; vaccinations; Epidemiology; epidemiologi;

    Sammanfattning : Background: Celiac disease occurs worldwide in approximately 1% of the population, whereof the majority of cases are undiagnosed. Sweden experienced an epidemic (1984-1996) of clinically detected celiac disease in children below 2 years of age, partly attributed to changes in infant feeding. LÄS MER
