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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Köping-Höggård; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; gene therapy; gene delivery; non-viral; polyplex; chitosan; chitosan oligomers; polyethylenimine; plasmid DNA; lung; Galenisk farmaci; PHARMACY Pharmaceutics; FARMACI Galenisk farmaci;

    Abstract : 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. READ MORE

    Abstract : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. READ MORE

  3. 3. Chitosan and chitosan/wheat gluten blends properties of extrudates, solid films and bio-foams

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Fei Chen; KTH.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents four different studis describing the characteristics and processing opportunities of two widely available biopolymers: chitosan and wheat gluten. The interest in these materials is mainly because they are bio-based and obtained as co- or by-products in the fuel and food sectorIn the first study, high solids content chitosan samples (60 wt.

    Abstract : Användningan av engångsförpackningar har ökat kraftigt de senaste åren. Den absolut största delen av dessa förpackningar tillverkars av oljebaserade plaster såsom polyetylen (PE) och polypropylen (PP). Dessa har även en oerhört lång nedbrytningstid, vilket gör det viktigt att finna mer miljövänliga alternativ. READ MORE
