  1. 1. Hydrological Transport in Shallow Catchments: : tracer discharge, travel time and water age

    Författare :Sofie Safeyeh Soltani; Vladimir Cvetkovic; Bijan Dargahi; Jan Olof Selroos; Andrea Rinaldo; KTH; []
    Nyckelord :Hydrological transport; travel time; water age; tracer discharge; Lagrangian pathway approach; pathway lengths; numerical modeling; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : This focuses on hydrological transport in shallow catchments with topography-driven flow paths. The thesis gives new insight to kinematic pathway models for estimation of tracer discharge at the catchment outlet. LÄS MER

  3. 2. The cholinergic anti-inflammatory pathway and heart rate variability with special reference to dialysis and renal denervation

    Författare :Marie Hilderman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The Cholinergic Anti-inflammatory Pathway (CAP) is a nerve-mediated circuit through which the vagus nerve regulates the activity of the inflammatory immune response. Injury, ischemia or infection activate the afferent vagus. In the medulla oblongata. LÄS MER

  4. 3. Regulation of protein degradation by virus derived repeated amino acid sequences

    Författare :Ainars Leonchiks; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Epstein-Barr virus; glycine-alanine repeat; ubiquitin-proteasome pathway;

    Sammanfattning : The ubiquitin-proteasome pathway plays a central role in the controlled degradation of short-lived and regulatory proteins important m a variety of cellular processes, including antigen presentation and combating viral infections. The presentation of antigenic peptides derived from ubiquitin-proteasome dependent degradation of vital proteins to MHC class I restricted cytotoxic T cells is a central component of antiviral responses.

  5. 4. Evolution of biological systems linked to complex cell architectures in Planctomycetota

    Författare :Emil Hägglund; Siv Andersson; Damien Devos; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Planctomcyetota; Cellular complexity; Gemmataceae; Phagocytocis; Serine Threonine kinase; Anammox; Hydrazine Synthase; Hydroxylamine oxidoreductase; Heme biosynthesis; Phylogenetics; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Sammanfattning : The eukaryotic cells have a nucleus and membrane-enclosed organelles for functions such as energy production, whereas the prokaryotic cells have a cell wall but no intracellular membrane-bound structures. Species of the Planctomycetota phylum are classified as bacteria but have diverse and complex cell architectures. LÄS MER

  7. 5. Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies

    Författare :Yasir Ruhayel; Malmö Molekylärgenetisk reproduktionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cytoplasmic and nuclear; Receptors; Prostatic neoplasms; genetic; Polymorphism; male; Infertility; Hypogonadism; Genetic association studies; Case–control studies; Androgens;

    Sammanfattning : Androgen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively.
