  1. 1. Atrial fibrillation – on its trigger mechanisms, risks and consequences

    Författare :Dritan Poci; Göteborgs universitet; []
    Nyckelord :acute coronary syndromes; atrial fibrillation; AV junctional ablation; CHADS2 score; electrical cardioversion; mortality; stroke; trigger mechanisms;

    Sammanfattning : Background: Atrial fibrillation (AF) frequently impairs quality of life, but in long-term it is associated with an increased morbidity and mortality. Persistent AF may cause changes in the sinus node function, and if converted to sinus rhythm (SR), there is a substantial risk of recurrence of AF. LÄS MER

  3. 2. Complement Activation Triggered by Biomaterial Surfaces : Mechanisms and Regulation

    Författare :Jonas Andersson; Bo Nilsson; Hans Elwing; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Biomaterials; Biocompatibility; Blood; Complement; Immunologi; Immunology; Immunologi; klinisk immunologi; Clinical Immunology;

    Sammanfattning : Today there are a vast number of medical devices in temporary or permanent contact with human tissues. Blood-biomaterial contact is known to trigger the complement system and results in generation of fluid phase anaphylatoxins C3a and C5a, and surface-bound C3b and iC3b. LÄS MER

  4. 3. OVULATION: Intra-ovarian mechanisms

    Författare :Farnosh Sørensen Zakerkish; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovulation; Human;

    Sammanfattning : Background: Ovulation is the central biological process involved in the menstrual cycle of women. Specifically, ovulation involves the tissue remodelling of the preovulatory follicle to achieve the rupture of the exterior follicle wall with the extrusion of the oocyte. LÄS MER

  5. 4. Proteostasis in Bacillus subtilis : chaperones and stress-response mechanisms

    Författare :Judith Matavacas; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein homeostasis; Chaperones; DnaK; trigger factor; Spx; YjbH; Bacillus subtilis;

    Sammanfattning : The maintenance of protein homeostasis, also referred to as proteostasis, is essential for preserving the structural and functional stability of the proteome in living organisms. This involves the precise control of protein synthesis, folding, and degradation. LÄS MER

  7. 5. Mechanisms of mechanically induced Osteoclastogenesis : in a novel in vitro model for bone implant loosening

    Författare :Cornelia Bratengeier; Anna Fahlgren; Per Aspenberg; Mikael Sigvardsson; Oran Kennedy; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Total joint arthroplasty is the primary intervention in the treatment of end-stage osteoarthritis. Despite the high success rate, in some patients, the replacement will fail during their lifetime requiring a revision of the implant. These revisions are strenuous for the patient and costly for health care. LÄS MER
