  1. 11. Fluorescence Properties of Quantum Dots and Their Utilization in Bioimaging

    Författare :Hao Xu; Ying Fu; Hjalmar Brismar; Marina Zelenina; Mattias Goksör; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fluorescence; Microscopy; Bioimaging; Nanomaterial; cytotoxicity; mechanism; Biological Physics; Biologisk fysik;

    Sammanfattning : Quantum dots (QDs), especially colloidal semiconductor QDs, possess properties including high quantum yields, narrow fluorescence spectra, broad absorption and excellent photostability, making them extremely powerful in bioimaging. In this thesis, we studied the fluorescence properties of QDs and attempted multiple ways to boost applications of QDs in bioimaging field. LÄS MER

  3. 12. Sensory mechanisms in the human upper airway - Role of TRP ion channels

    Författare :Lisa Alenmyr; Avdelningen för klinisk kemi och farmakologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TRPV1; TRPV4; TRPA1; allergic rhinitis; itch; rhinorrhea; MUC5B; MUC5AC; epithelial;

    Sammanfattning : The nasal mucosa is richly innervated with sensory nerves having the ability to detect changes in the environment and mediate symptoms such as secretion and itch. Some TRP ion channels such as TRPV1 and TRPA1 are abundantly expressed in sensory nerves and respond to a wide variety of stimuli, including irritants, inflammatory mediators and temperatures.

  4. 13. Regulation and function of ciliary dyslexia candidate genes

    Författare :Andrea Bieder; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Dyslexia is defined as an unexpected difficulty in reading despite normal intelligence, senses and instruction. It is the most common learning disability with estimated 5-10% of the population affected. Its heredity is estimated to about 40-60%. LÄS MER

  5. 14. The Horizontal Ussing Chamber Method in Studies of Nasal Drug Delivery : Method Development and Applications Using Different Formulations

    Författare :Karin Östh; Anna-Lena Ungell; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; FARMACI; PHARMACY; FARMACI; galenisk farmaci; Pharmaceutics;

    Sammanfattning : The results from this thesis leads to the following conclusions; HUM is a useful tool that fills a gap in the in vitro methods previously available to study nasal drug delivery. Using HUM, the pig respiratory nasal mucosa can obtain acceptable viability and retain it longer than the period of time needed for a transport experiment. LÄS MER

  7. 15. The role of RFX transcription factors in neurons and in the human brain

    Författare :Debora Sugiaman-Trapman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : RFX transcription factors (TFs) are conserved in animals, fungi and some amoebae, but not in algae, plants and protozoan species. The conservation is based on the protein sequence of the DNA binding domain (DBD). The RFX DBD recognizes and binds to a DNA sequence motif called the X-box. LÄS MER
