  1. 21. Blood interactions with bioactive peptidefunctionalized nanocellulose : An evaluation of the activation of the coagulation and complement system

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Vanisha Bansal; [2022]
    Nyckelord :;

    Sammanfattning : A current trend utilizing the biomedical approach in the field of wound care is focused on the increased potential to develop wound healing materials designed to address specific types of wounds or underlying pathologies to achieve improved healing. The work presented in this thesis evaluates the blood response to wood-derived nanocellulose functionalized with a peptide, with the ultimate aim of characterizing the material as a potential wound dressing for chronic wound care.

  3. 22. Using metabolic profiles to screen for novel compounds in deep-sea sponges

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

    Författare :Samira Hilowle; [2022]
    Nyckelord :Metabolomics; Deep-sea sponges;

    Sammanfattning : The chemical diversity of the phylum Porifera have provided marine natural products (MNPs) such as alkaloids, terpenoids and peptides with ranging biological activity. Every two days a novel compound deriving from sponges are discovered. LÄS MER

  4. 23. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  5. 24. Haltbestämning av flavanoider i hantverksmässigt tillverkad choklad

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Patrik Petersson; [2021]
    Nyckelord :Hälsopåstående; kakao; flavonoider; kakaoflavanoler; coachning; High Performance Liquid Chromatography; HPLC;

    Sammanfattning : Choklad erhålls från kakaobönan som är frukten på kakaoträdet (Theobroma cacao). För att skapa choklad bearbetas kakaobönan vilket påverkar halten av bioaktiva ämnen i produkten. Choklad innehåller flera typer av bioaktiva ämnen där kakaoflavanolerna epikatechin och katechin är de mest framträdande. LÄS MER

  7. 25. 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.
