    Sammanfattning : With the recent advantages of machine learning in cheminformatics, the drug discovery process has been accelerated; providing a high impact in the field of medicine and public health. Molecular property and activity prediction are key elements in the early stages of drug discovery by helping prioritize the experiments and reduce the experimental work. LÄS MER

  4. 3. Using effect-based methods to evaluate the presence of bioactive compounds in food contact materials made of paper and cardboard

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Mimmi Wänn; [2021]
    Nyckelord :Food toxicology; food contact materials; cell-based in vitro bioanalytical methods; cytotoxicity; reporter gene assay; bioactivity; bioassays; paper and cardboad;

    Sammanfattning : Food contact materials are materials that are intended to come into contact with food, and we are exposed to different types of chemicals that exist in the packages on a daily basis. In this study, a battery of effect‑based in vitro cellular bioassays was used to evaluate the presence of bioactive compounds in commonly used food contact materials made of paper and cardboard, retrieved from the Swedish market.

  5. 4. Engineering Vascularized Skin Tissue in a 3D format supported by Recombinant Spider Silk

    Master-uppsats, KTH/Proteinteknologi

    Författare :Savvini Gkouma; [2020]
    Nyckelord :skin; BSE; bilayered skin tissue equivalent; 3D; in vitro; model; vascularized; recombinant spider silk; FN-4RepCT; dermis; epidermis;

    Sammanfattning : Skin is an organ with a complex structure which plays a crucial role in thebody’s defence against external threats and in maintaining major homeostatic functions. The need for in vitro models that mimic the in vivo milieu is therefore high and relevant with various applications including, among others, penetration, absorption, and toxicity studies. LÄS MER

  7. 5. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER
