  1. 16. Autophagy and senescence in primary human bronchial epithelial cells in the context of COPD

    Master-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Annie Vegraeus; [2023]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Chronic obstructive pulmonary disease (COPD) is the third largest cause of death worldwide, with its most prominent risk factor being inhalation of smoke and pollutants. In this project, we studied two processes that are involved in COPD: autophagy and cellular senescence. LÄS MER

  3. 17. Image-Based Classification Solutions for Robust Automated Molecular Biology Labs

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Arnold Teo; [2023]
    Nyckelord :Neural networks; Deep learning; Transfer learning; TensorFlow; Single-cell genomics; Image classification; Neurala nätverk; Djupinlärning; Överförd inlärning; TensorFlow; Enskild cellgenomik; Bildklassificering;

    Sammanfattning : Single-cell genomics (SCG) are methods for investigating heterogeneity between biological cells, among these is Smart-seq which sequences from RNA molecules. A more recent version of this method is Smart-seq3xpress which is currently in the process of being automated by the Sandberg lab at Karolinska Institutet. LÄS MER

  4. 18. Buffer modification: A case study with polystyrene beads, DU145-, and MCF7 cell lines

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Olivia Hansson Rengbrandt; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Separation of cancer cells gives advantages in understanding the disease, guiding treatment decisions, and facilitating drug development. Overall, separation plays an important role in biological research. Acoustophoresis is a technique that utilizes acoustic waves to separate particles and cells suspended in a buffer medium. LÄS MER

  5. 19. Towards time-resolved cryo-EM of SARS-CoV-2 replication-transcription complex and Staphylococcus aureus DNA gyrase

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Anna Králová; [2023]
    Nyckelord :time-resolved cryo-EM; DNA gyrase; SARS-CoV-2; replication-transcription complex; protein purification;

    Sammanfattning : Time-resolved cryo-EM has already provided ground-breaking discoveries in various fields, including structural biology, biochemistry, and drug development. Compared to traditional structural biology methods where mostly stabilized conformations are reconstructed, the main advantage of time-resolved cryo-EM is its ability to capture dynamic processes in biological samples at near-atomic resolution, which allows for studying biological structures as they change and interact in real-time.

  7. 20. Production of succinic acid by Actinobacillus succinogenes in attached-growth bioreactors and dynamic modelling of biofilm formation

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Henrik Östberg; [2023]
    Nyckelord :Actinobacillus succinogenes; Succinic acid; Biofilm; Attached-growth bioreactor; Dynamic modelling; Cell cultivation; Applied microbiology; Biology and Life Sciences;

    Sammanfattning : Actinobacillus succinogenes is a microorganism is a very efficient producer of succinic acid, a chemical with a wide range of industrial applications. The bacterium is prone to form biofilm, a flocculation of cells attached to a surface. LÄS MER
