    Sammanfattning : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. LÄS MER

  3. 2. Syntheses and Evaluation of Peptoids as Bioinert Coatings for Nanoparticles

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Christoffer Weber; [2018]
    Nyckelord :Peptoid; Antifouling; Polymer coating; Organic chemistry; Organisk kemi; Chemistry;

    Sammanfattning : Polymers of N-substituted glycine (NSG) or as they are also called, peptoids, have shown potential in biomedical applications due to proteolytic resistance, among other interesting properties. In this thesis project, two synthetic routes have been performed and evaluated to achieve a better understanding of large-scale syntheses of peptoids as a bioinert coating for nanoparticles. LÄS MER

  4. 3. The pig as an animal model for kidney transplantation

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Martina Zakariasson; [2016]
    Nyckelord :pig; kidney; transplantation; rejection; ischemia reperfusion;

    Sammanfattning : A significant amount of the world’s population suffers from chronic kidney disease. Renal failure arises when less than 25 % of the kidneys function properly. The treatments available for humans that suffer from renal failure are dialysis or renal transplantation, of which transplantation is considered to be the treatment of choice. LÄS MER

  5. 4. Performance analysis of a PEGylation process -Process comparison of a tubular reactor with recirculation to a conventional batch reactor

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Boris Torbica; [2015]
    Nyckelord :Ion Exchange Chromatography; Recirculation; Tubular reactor; Tube reactor; PEGylation; PEG Polyethylene glycol; IEC; Optimisation; Chemical Engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Since the rise of therapeutical proteins, there has been a growing interest in biopharmaceuticals over the years. Research was made to combat various protein weaknesses like fast degradation and low solubility. A discovery in the 1970s suggested that an attachment of polyethylene glycol (PEG) on protein surfaces would solve the specific problems. LÄS MER

  7. 5. Är Renminbin undervärderad?

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Sammanfattning : Kina har haft en exceptionell utveckling tiden efter den ekonomiska reformen 1979 då den kinesiska regeringen började öppna upp den interna marknaden för internationell konkurrens. Resultatet har visats sig i växande valutareserv och bytesbalans och framförallt i tilltagande BNP tillväxt. LÄS MER
