  1. 1. Let Us Put Our Brains in the Spotlight – Literally!

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Elsa Karjalainen; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Neurons are the working force in each vertebrate’s nervous system. These small cells have the important task of transferring information in the form of electrical charges called action potentials. Neurons make it possible for us to sense touch, process our environment, and store memory. LÄS MER

  3. 2. Method development of an in vitro vertical Franz diffusion cell system to assess permeation of cosmetic active ingredients

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Johanna Mattiasson; [2020]

    Sammanfattning : For evaluation of potential skincare ingredients, an in-house method using Static Franz diffusion cells and dialysis membranes was developed. Benzoic acid was chosen as a model substance along with L-ascorbic acid and α-Tocopherol. The cell conditions were tailored to encourage transmembrane diffusion. LÄS MER
