  1. 1. Study of surfactant-preservative and protein-preservative interactions in multi-dose injectable formulation

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Javier Lagares Martín; [2023]
    Nyckelord :Phenol; polysorbate 80; cloud point; somatropin; aggregation; titration; light scattering; salt; surfactant; preservative; protein; tonicity adjusting agents; multi-dose injectable formulation; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : Multidose injectable formulations require a preservative such as phenol to ensure sterility and protection against microbial contamination during clinical use. However, it is known that the interaction between these components and non-ionic surfactants such as polysorbate 80, also found in this type of formulations, present incompatibilities, which can lead to decreases in the efficacy of the product.

  3. 2. Scandinavian Mummies : Interpreting the preservative qualities of Danish Bronze Age Mounds

    Kandidat-uppsats, Uppsala universitet/Institutionen för arkeologi och antik historia

    Författare :Ellinor Grönkvist; [2023]
    Nyckelord :Burial mounds; Bronze Age; Denmark; Preservation; Oak-log coffins; Gravhögar; Bronsålder; Danmark; Bevarande; Ekstockskistor;

    Sammanfattning : This paper explores/investigates the circumstances around the unusual level of preservation of organic materials within certain mounds in Jutland, Denmark, as well as the scientific benefits of these findings. These mounds contain coffins made from oak-logs and within them mummies of different degree of preservation have been found. LÄS MER

  4. 3. Phenol-Protein Solution Stability

    Magister-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Johan Sjölund; [2022]
    Nyckelord :Phenol; Protein; Proteins; Lysozyme; Betalactoglobulin; Trastuzumab; Lipase; GAZ; GA-Z; Palifermin; Titration; Probedrum; Pharmaceutical Technology; Chemistry;

    Sammanfattning : Phenol is a commonly used preservative in pharmaceutical protein solutions. It is compatible with most proteins but can cause aggregation and denaturation at higher concentrations or in more sensitive proteins. LÄS MER

  5. 4. Adaptive Reuse for Hasten 21

    Master-uppsats, KTH/Arkitektur

    Författare :Lin Yu; [2022]
    Nyckelord :building heritage; adaptive reuse; Bengt Lindroos; Post Modernism;

    Sammanfattning : Passagenhuset, a historical building marked green by Stockholm City Museum, is under threat. In the 2017 proposal by Pembroke, it is to be demolished and replaced with a 14-storey tall glazing building. The protest against this proposal paused the demolition of Passagenhuset. There has been a renowned aggressive preservation culture in Sweden. LÄS MER

  7. 5. Effekten av substansen propylenglykol på stafylokocker från human hud

    Uppsats för yrkesexamina på grundnivå, Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Författare :Alexandra Uppström; [2021]
    Nyckelord :Broth dilution; human microbiome; MBC; MIC; propylene glycol; skin; staphylococcus; Buljongspädningsmetoden; hud; MBC; MIC; normalflora; propylenglykol; stafylokocker;

    Sammanfattning : Hudens normalflora består av lågpatogena bakterier där stafylokockerna är de vanligaste förekommande bakterierna. Studier visar att antimikrobiella medel kan förändra hudbakteriepopulationer och att dessa förändringar kan leda till kritiska konsekvenser för hudens försvar. LÄS MER
