  1. 21. Platelet-mediated inhibition of polymorphonuclear neutrophil apoptosis

    Författare :Jenny Larsson; Maurice B. Hallett; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Neutrophils play an important role in the cell-mediated immune response against invading micro-organisms. Upon infection, neutrophils in the bloodstream transmigrate into the tissue where they bind to and engulf the microbes. The infecting agent is then eliminated using reactive oxygen species (ROS) and proteolytic enzymes. LÄS MER

  3. 22. Novel microfluidic based sample preparation methods for rapid separation and detection of viable bacteria from blood for sepsis diagnostics

    Författare :Sharath Narayana Iyengar; Aman Russom; Jonas Tegenfeldt; KTH; []
    Nyckelord :microfluidics; Bioteknologi; Biotechnology;

    Sammanfattning : Sepsis is a serious medical condition characterized by a whole-body inflammatory response caused by bloodstream infection. The final stage of sepsis can lead to septic shock, multiple organ failure, and death. In early sepsis, the concentration of bacteria in the bloodstream is typically low, making diagnosis challenging. LÄS MER

  4. 23. Neutropenic fever during treatment of hematological malignancy : etiology and diagnostics

    Författare :Lennart Persson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Fever is the principal and sometimes the only manifestation of serious infection in the neutropenic patient because signs of inflammation may be minimal or absent in this group of patients. The aim of this thesis was to improve the clinical management of the febrile neutropenic patient. LÄS MER

  5. 24. Advances in DNA Detection

    Författare :Yajing Song; Olof Emanuelsson; Jonas Tegenfeldt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DNA detection; active filter paper; visual detection; throughput; fluorescence; superparamagnetic beads; rare DNA; Q-PCR; chemical fragmentation; DNA library preparation; massively parallel sequencing; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Sammanfattning : DNA detection technologies have an increasing importance in our everyday lives, with applications ranging from microbial diagnostics to forensic analysis, food safety evaluation, and environmental monitoring. Currently, as the associated costs decrease, DNA diagnostic techniques are routinely used in research laboratories, in clinical and forensic practice. LÄS MER

  7. 25. Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

    Författare :Hulda Thorarinsdottir; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombosis; critical illness; biofilm; intratracheal intubation; ventilator-associated pneumonia; ; central venous catheters; catheter-related infections; proton pump inhibitors; oropharynx; MICROBIOTA; foreign-body reaction; hemolysis; inflammation;

    Sammanfattning : Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. LÄS MER
