  1. 1. Coagulation process characteristics and pollutant removal from urban runoff

    Författare :Fredrik Nyström; Inga Herrmann; Annelie Hedström; Maria Viklander; Michael Cimbritz; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stormwater; urban snowmelt; road runoff; coagulation flocculation sedimentation; coagulation characteristics; coagulation mechanism; treatment efficiency; VA-teknik; Urban Water Engineering; Centre - Centre for Stormwater Management DRIZZLE ; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ;

    Sammanfattning : Many different stormwater control measures (SCMs) can be implemented in order to mitigate issues with polluted stormwater flows into receiving water bodies.  The treatment function of  SCMs is commonly based on the removal of particles by sedimentation, thereby also removing pollutants associated with particles.

  3. 2. Contact activation on bacterial surfaces - a virulence mechanism

    Författare :Kristin Persson; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General biomedical sciences; Biomedicinska vetenskaper allmänt ; sepsis; infection; S. aureus; S. typhimurium; E. coli; curli; fibrinopeptides; fibrinogen; Coagulation; contact system;

    Sammanfattning : Life-threatening conditions from bacterial infections are a major clinical problem. During a severe infection, the host responds by a massive release of pro-inflammatory mediators together with a systemic activation of systems such as the coagulation, fibrinolytic, and complement systems.

  4. 3. Tissue Factor Biological Functions : Coagulation Activity in Microparticles and Signaling with Focus On Migration and Apoptosis

    Författare :Mikael Åberg; Agneta Siegbahn; Carl-Henrik Heldin; Teet Velling; Björn Dahlbäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue factor; Apoptosis; Migration; Chemotaxis; Simvastatin; Platelet Derived Growth Factor; Cell Signaling; Microparticles; Prostasomes; Trombosis; Coagulation; Prostate Cancer; Breast Cancer; Caspase-3; Caspase-8; NFkappaB; PAR2; Transactivation; Monocytes; Clinical chemistry; Klinisk kemi;

    Sammanfattning : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein known as the main initiator of blood coagulation. TF is over-expressed on many malignant cells and apart from increasing the risk of thrombosis, the presence of TF/FVIIa also promotes the progression of cancer and metastasis by intracellular signaling.

  5. 4. Tissue Factor regulation, signaling and functions beyond coagulation with a focus on diabetes

    Författare :Desireé Edén; Agneta Siegbahn; Sofia Ramström; Uppsala universitet; []
    Nyckelord :Tissue factor; diabetes; cell signaling; coagulation; beta cells; adipocytes; apoptosis; lipolysis; micro RNA; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Background: Tissue factor (TF) is a 47 kDa transmembrane glycoprotein best known for initiating the coagulation cascade upon binding of its ligand FVIIa. Apart from its physiological role in coagulation, TF and TF/FVIIa signaling has proved to be involved in diseases such as diabetes, cancer and cardiovascular diseases. LÄS MER

  7. 5. Functional study of hemolymph coagulation in Drosophila larvae

    Författare :Zhi Wang; Ulrich Theopold; Brian Lazzaro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; innate immunity; hemolymph coagulation; clot components; Drosophila larvae; Molecular Biology; molekylärbiologi;

    Sammanfattning : Many pathogen infections in nature are accompanied by injury and subsequent coagulation. Despite the contribution of hemolymph coagulation to wound sealing, little is known about its immune function. LÄS MER
