  2. 1. Haemophilia B - Diagnostic Insights, Genetic Aspects and Clinical Outcomes

    Author : Kristina Kihlberg; Institutionen för translationell medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coagulation factor IX; Haemophilia B; Haemophilia A; F9 variant; Assay discrepancy; Chromogenic assay; One-stage assay; Bleeding disorders; Quality of life; Immune tolerance induction; Non-neutralising antibodies; Inhibitors; Treatment Adherence; Arthropathy;

    Abstract : Haemophilia B (HB) is a rare inherited bleeding disorder caused by the deficiency of coagulation factor IX (FIX). The major clinical issues are bleedings, often targeting the joints, and the development of neutralising antibodies, i.e. inhibitors, to the FIX replacement therapy. READ MORE

  4. 2. Advanced molecular tools for diagnostic analyses of RNA and antibodies in situ and in solution

    Author : Mengqi Wang; Ulf Landegren; Anders Ståhlberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Homogenous serological assay; PCR-based antibody detection; Proximity extension assay; SARS-CoV-2 antibody; Extracellular vesicles; Proximity barcoding assay; in situ superRCA; mutant transcript;

    Abstract : Advanced molecular diagnostics uses in vitro biological assays to detect nucleic acids or proteins even in low concentrations across samples, allowing for the identification of biomarkers, monitoring the course of the disease over time, and selection of appropriate therapy. In this thesis, I focus on development and early applications of several molecular tools of expected value in research, and eventually also clinically. READ MORE

  5. 3. Tethered Lipid Vesicles as Nanoscale Sensor Elements

    Author : Seyed Tabaei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aquaglyceroporin; lipid vesicles; total internal reflection fluorescence TIRF microscopy; cell membrane; aquaporin; pore formation; surface plasmon resonance SPR ; phospholipase A2; antiviral peptide; lipid bilayer; biosensing; microfluidics;

    Abstract : The primary aim of this thesis work has been to explore and advance the potential of surface tethered lipid vesicles as a platform for studying in particular the following three biomembrane-related processes: trans-membrane transport, membrane-peptide interactions and the activity of membrane active enzymes. First, a method based on surface plasmon resonance (SPR) spectroscopy was developed for studying passive diffusion processes as well as the membrane-protein mediated transport of small non electrolyte molecules across lipid bilayers.

  6. 4. Novel diagnostic microarray assay formats towards comprehensive on-site analysis

    Author : Jesper Gantelius; Helene Andersson-Svahn; Christer Wingren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic microbeads; gold nanobeads; microarrays; lateral flow; on-site diagnosis; SNPs; pestivirus; autoimmunity; contagious bovine pleuropneumonia; comsol multiphysics; finite element method; Microbiology; Mikrobiologi; Biochemistry; Biokemi;

    Abstract : Advances in molecular methods for analyzing DNA, RNA and proteins in humans as well as in other animals, plants, fungi, bacteria or viruses have greatly increased the resolution with which we can study life’s complexity and dynamics on earth. While genomic, transcriptomic and proteomic laboratory tools for molecular diagnosis of disease are rapidly becoming more comprehensive, the access to such advanced yet often expensive and centralized procedures is limited.

  7. 5. Diagnostic and prognostic markers in sepsis

    Author : Patrik Gille-Johnson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Sepsis is a life-threatening disease affecting millions of people globally. The more severe forms are considered to be a consequence of an unbalanced systemic inflammatory response to infection, causing organ dysfunction, vascular leakage and hypotension. An early diagnosis followed by appropriate antimicrobial therapy is critical for the outcome. READ MORE
