  1. 1. Sample Preparation Optimization for Laboratory Soft X-Ray Microscopy

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Haya Amer Abduljabar; [2022]
    Nyckelord :Soft X-rays; Stockholm laboratory soft X-ray microscope; Sample preparation; Nanoparticles; Macrophages; Mjuka röntgenstrålar; Stockholm laboratoriets mjuka röntgenmikroskop; Provberedning; Nanopartiklar; Makrofager;

    Sammanfattning : With the introduction of nanoparticles in health care and daily products, the interaction between cells and nanoparticles is of great interest. There are many ways to examine these interactions, one of them being soft X-ray microscopy. LÄS MER

  3. 2. Expression of FLAG-tagged argonautes in Dictyostelium discoideum

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för cell- och molekylärbiologi

    Författare :Zozek Abdul Rahman; [2022]
    Nyckelord :Dictyostelium; discoideum; Argonaute; Protein; FLAG; FLAG-tag; Molecular Biology; Microbiology; SorMC; agnA; agnC; agnE; electrophoresis; pDM304;

    Sammanfattning : Argonautes are conserved RNA-binding proteins that can regulate gene expression post transcriptionally through a process known as RNA interference (RNAi). This is done through the use of small RNAs, e.g. sRNAs that act as a guide for the argonautes, allowing for sequence-specific binding to the target site. LÄS MER

  4. 3. Search for the Argonaute protein that governs miRNA regulation in Dictyostelium discoideum

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Miranda Åström; [2021]
    Nyckelord :Argonaute proteins; RNA interference; miRNA; 3xFLAG-tag;

    Sammanfattning : MicroRNAs are small non-coding RNAs that regulate gene expression through RNA interference. These small RNAs enact gene silencing by forming a RNA-inducing silencing complex together with the effector protein Argonaute. The function of the Argonautes in the social amoeba Dictyostelium discoideum is not yet fully understood. LÄS MER

  5. 4. The Infection and Uncoating Mechanism of the Giant Melbournevirus

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sahar Shammakhi; [2020]
    Nyckelord :Giant viruses; Infection mechanism; amoeba; LC-MS MS;

    Sammanfattning : Since their 'discovery' at the turn of the 21st century, giant viruses of the amoeba have captured the fascination of virologists. They have raised a plethora of questions regarding their evolution and ecological significance and have greatly defied a century's old definition of viruses. LÄS MER

  7. 5. Sustainability Evaluations and Development Challenges of Cacao Farms : A Minor Field Study in Huila, Colombia

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Elin Pettersson; [2016]
    Nyckelord :Theobroma cacao L.; agroecology; agroecosystem; agroforestry; participatory research;

    Sammanfattning : An intensification of 200 000 tonnes of cacao is planned for the Colombian cacao production until 2021. This could lead large negative effects on the Colombian nature and biodiversity if the current smallholdings of agroforestry were abandoned in favour for large monocultures. LÄS MER
