  1. 1. Chromoendoscopy with particular reference to a modified endoscopic Congo red test

    Författare :Ervin Toth; Gastroenterologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastroenterologi; Gastro-enterology; therapy; diagnosis; gastrointestinal endoscopy; Chromoendoscopy; Congo red;

    Sammanfattning : Chromoendoscopy, endoscopic tissue staining, is an adjunctive method using chemical agents applied to the mucosal surface in order to aid gastrointestinal endoscopic diagnosis and therapy. Acid producing mucosa in the GI tract may be visualized endoscopically by Congo red staining in combination with stimulation of gastric acid production. LÄS MER

    Sammanfattning : Alzheimer’s disease is an incurable neurodegenerative disorder linked to the amyloid β (Aβ) peptide, a 38-43 residue peptide. The detailed molecular disease mechanism(s) is (are) unknown, but oligomeric Aβ structures are proposed to be involved. LÄS MER

  3. 3. Functionalization, Characterization and Applications of Oxidized Nanocellulose Derivatives

    Författare :Chang-Qing Ruan; Lindh Jonas; Strømme Maria; Mathew Aji P; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocellulose; Periodate oxidation; Oxone oxidation; Adsorption; Palladium; Congo red dye; Cellulose nanofibers; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : Cellulose, a sustainable raw material derived from nature, can be used for various applications following its functionalization and oxidation. Nanocellulose, inheriting the properties of cellulose, can offer new properties due to nanoscale effects, in terms of high specific surface area and porosity. LÄS MER

  4. 4. Fluorescent thiophene-based ligands for detection and characterization of disease-associated protein aggregates

    Författare :Therése Klingstedt; Peter Nilsson; Per Hammarström; Henrik Zetterberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis the unique optical properties of fluorescent ligands termed luminescent conjugated oligothiophenes (LCOs) have been used to study a variety of protein aggregates associated with human protein misfolding disease. This heterogeneous group of diseases contains well known and fatal members such as Alzheimer´s and Huntington´s disease and the development of sensitive tools for the detection and characterization of protein aggregates is crucial for unravelling the complexity of these pathologies.
