  1. 1. Interactions between platelets and complement with implications for the regulation at surfaces

    Author : Per H. Nilsson; Kristina Nilsson Ekdahl; John Lambris; Ian Nicholls; Berhane Ghebrehiwet; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; complement system activation; regulation ; platelets activation; regulation ; biomaterials; biocompatibility; chondroitin sulfate-A; apyrase; C1q; C3; factor H; C4BP; ADP; Biomedical Sciences; Biomedicinsk vetenskap;

    Abstract : Disturbances of host integrity have the potential to evoke activation of innate immunologic and hemostatic protection mechanisms in blood. Irrespective of whether the activating stimulus is typically immunogenic or thrombotic, it will generally affect both the complement system and platelets to a certain degree. READ MORE

  2. 2. The role of the thromboinflammatory response under hemolytic conditions : pathophysiological mechanisms and therapeutic inhibition

    Author : Alexandra Gerogianni; Per H. Nilsson; Camilla Mohlin; Tom Eirik Mollnes; Kristina Nilsson Ekdahl; Mihály Józsi; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hemolysis; heme; thromboinflammation; biomaterials; complement inhibition; LVAD; IONPs; Biomedical Sciences; Biomedicinsk vetenskap; Immunologi; Immunology;

    Abstract : In blood circulation, the complement and the coagulation cascades, together with platelets and endothelial cells form a complex network of crosstalk. When dysregulated, these interactions can lead to inflammation in combination with thrombosis (thromboinflammation) and the manifestation of pathophysiological complications. READ MORE

  3. 3. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Author : John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. READ MORE

  4. 4. Hemiparasites in the Subarctic: Resource acquisition, growth and population dynamics

    Author : Carin H Nilsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; population dynamics; selectivity; Phenotypic plasticity; fitness; Plant ecology; Växtekologi;

    Abstract : Parasitic plants are found in nearly every major terrestrial ecosystem and can be divided into two groups, holoparasites (lacking chlorophyll) and hemiparasites (chlorophyllous). The host-parasite connection is either situated above (stem parasites) or below ground (root parasites). READ MORE

  5. 5. Ischaemic heart disease - risk assessment, diagnosis, and secondary preventive treatment in primary care : with special reference to the relevance of exercise ECG

    Author : Gunnar Nilsson; Eva Samuelsson; Thomas Mooe; Per Wändell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise ECG; Ischaemic heart disease; Myocardial infarction; Prehospital delay; Primary care; Prognosis; Referral; Statin; Secondary prevention; Arbets-EKG; hjärtinfarkt; ischemisk hjärtsjukdom; sekundärprevention; Family Medicine; allmänmedicin;

    Abstract : Background: Ischaemic heart disease is a diagnostic and therapeutic challenge to most general practitioners. We sought to identify diagnostic characteristics and prognoses of patients in primary care that received exercise electrocardiography (ECG). We compared the ECG test results with respect to probability of subsequent cardiologist referrals. READ MORE
