  1. 1. Transient state UV spectroscopy of Tyrosine and Tyrosine-containing protein

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Hongjian Chen; [2023]
    Nyckelord :Tyrosine; Calmodulin; Autofluorescence; Transient-state monitoring; Electronic state transitions; Tyrosin; Calmodulin; Autofluorescens; Transient-tillståndsövervakning; Elektroniska tillståndsövergångar;

    Sammanfattning : The aromatic amino acids tryptophan, tyrosine, and phenylalanine have been extensively used for different label-free protein studies. These investigations extract information on protein conformations and interactions from the emitted fluorescence's intensity, wavelength, and/or polarization. LÄS MER

  3. 2. 3′-end fluorescence labelling of long RNAs using terminal deoxynucleotidyl transferase

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Johannes Lidberg; [2022]
    Nyckelord :Physical biochemistry; Fluorescence; In vitro transcription; RNA; Terminal deoxynucleotidyl transferase; Nucleobase analogue; Chemistry;

    Sammanfattning : Through recent years, RNA has rapidly gone from mainly being known as a passive information-carrying molecule within the central dogma of molecular biology to becoming the active ingredient in multiple therapeutics, such as in vaccines and potential drugs against cancer. However, one of the main challenges with RNA as a therapeutic is efficient delivery to cells. LÄS MER

  4. 3. Characterisation of structure and stability differences between the C-lobes of human and P. falciparum calmodulin in the presence of calmidazolium

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Igor Blagojevic; Klara Enockson; Marcus Miras Landelius; Ylva Strid Holmertz; Emelie Weinesson; Emma Örnelöw; [2022]
    Nyckelord :Calmodulin; Calmidazolium; Plasmodium falciparum; Malaria; Fluorescence spectroscopy; UV spectroscopy; CD; Circular dichroism; bioinformatics;

    Sammanfattning : Malaria is a serious disease that can lead to fatal consequences if not treated. It is mainly spread via Plasmodium falciparum, a parasite carried by mosquitoes as host organisms. As a potential way of treating malaria, research is being done on possible inhibitors of calmodulin (CaM) in the parasite. LÄS MER

  5. 4. Investigation of Thermal Maturity of  Organic Matter at the Cambro Ordovician Transition in the Zagros Basin, Iran

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Niall Gibbons; [2021]
    Nyckelord :acritarchs; thermal maturity; Zagros Basin; hydrocarbons; source rocks; paleoenvironment;

    Sammanfattning : The thermal maturity of sediments from the upper Cambrian to lower Ordovician Mila and Ilbeyk  formations in the Zagros Basin in southwestern Iran is evaluated in this thesis. A number of low-cost,  fast, optical evaluation methods are utilised to assess their effectiveness for providing accurate, well  constrained thermal maturity results. LÄS MER

  7. 5. Ancient plant cuticle chemistry: preservation and characterization of organic matter as biomarker of past UV-B radiation

    Master-uppsats, KTH/Kemi

    Författare :Larissa Lopes Cavalcante; [2021]
    Nyckelord :UACs; fossil cuticle; p-coumaric acid; ferulic acid; UV-B proxy; micro-FTIR; confocal Raman microscope; UAF; fossil kutikula; p-kumarinsyra; ferulinsyra; UV-B-proxy; mikro-FTIR; konfokalt Raman-mikroskop;

    Sammanfattning : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. LÄS MER
