    Författare :Weifeng Zhao; Ann-Chiristine Albertsson; Ulrica Edlund; Karin Odelius; Elisabet Brännvall; Peter Plikk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrically conductive; hemicellulose; hydrogels; swelling behavior; aniline oligomers; renewable; polymer synthesis; Elektriskt ledande; hemicellulosa; hydrogel; svällning; anilinoligomerer; förnyelsebar; polymersyntes; Kemi; Chemistry;

    Sammanfattning : Hydrogels have been extensively explored and are widely used in diverse biomedical applications, such as scaffolds for tissue engineering and vehicles for drug delivery. As one type of important natural polymer-based hydrogel, hemicellulose hydrogels have interesting attributes, including being renewable, non-toxic, biocompatible, biodegradable, and abundantly available.

  3. 22. Living biohybrid systems via in vivo polymerization of thiophene oligomers

    Författare :Gwennaël Dufil; Eleni Stavrinidou; Daniel T Simon; David C. Martin; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conducting polymers; Living tissue engineering; In vivo polymerization; Plant Biohybrids; Hydra polyps; Energy storage; Glucose sensor;

    Sammanfattning : Life is the result of a multitude of electrical signals which drives our nervous system but also accomplishes a cascade of electrochemical reactions. In the 18th century, Lucia Galeazzi and Luigi Galvani got the idea to stimulate frog legs with electrodes. LÄS MER

  4. 23. Chitosan Polyplexes as Non-Viral Gene Delivery Systems : Structure-Property Relationships and In Vivo Efficiency

    Författare :Magnus Köping-Höggård; Per Artursson; Jean-Paul Behr; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gene therapy; gene delivery; non-viral; polyplex; chitosan; chitosan oligomers; polyethylenimine; plasmid DNA; lung; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

    Sammanfattning : The subject of this thesis was to develop and optimize delivery systems for plasmid DNA (pDNA) based on biocompatible polymers, in particular chitosan, suitable for non-viral gene therapy. At the onset of this thesis, studies had reported conflicting results on the efficiency of chitosan-based gene delivery systems. LÄS MER

  5. 24. Studies of α-synuclein Oligomers-with Relevance to Lewy Body Disorders

    Författare :Therese Fagerqvist; Martin Ingelsson; Joakim Bergström; Lars Lannfelt; Michael G Schlossmacher; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha-synuclein; Parkinson´s disease; Lewy body dementia; Oligomer; Monoclonal antibody; Immunotherapy; Reactive aldehydes; Medical Science; Medicinsk vetenskap;

    Sammanfattning : The protein alpha-synuclein (α-synuclein) accumulates in the brain in disorders such as Parkinson’s disease (PD) and dementia with Lewy bodies (DLB). It is believed that the monomeric form of α-synuclein can adopt a partially folded structure and start to aggregate and form intermediately sized oligomers or protofibrils. LÄS MER
