  1. 1. Role of androgen receptor signaling in the activation and differentiation of plasmacytoid dendritic cells

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Faiza Tahsin Rashid; [2023-06-27]
    Nyckelord :;

    Sammanfattning : Androgens are steroid hormones essential for the development and maintenance of male reproductive organs and secondary sexual characteristics. Plasmacytoid dendritic cells (pDCs) are immune cells that act as the first line of defense against viral infections. LÄS MER

  3. 2. Characterization of Antigenic Properties of Two Immunogenic Proteins of Streptococcus pneumoniae 

    Master-uppsats, Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Mawj Jasimalsalih; [2023]
    Nyckelord :Immunogenic Proteins; PrsA; MalX; Membrane Vesicles; Protein Properties; Streptococcus pneumoniae virulence factors;

    Sammanfattning : The bacterium Streptococcus pneumoniae (pneumococcus), is considered to be a leading cause of morbidity and mortality globally, particularly in infants and the elderly. It is one of the most frequent causes of respiratory tract infections, which sporadically have the potential to develop into serious invasive symptoms including sepsis and meningitis. LÄS MER

  4. 3. A Game-theoretical Framework for Byzantine-Robust Federated Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Wanyun Xie; [2022]
    Nyckelord :Game theory; distributed robust learning; training-time attacks; exploration-exploitation tradeoff; Spelteori; distribuerad robust inlärning; attacker på träningstiden; kompromiss mellan utforskning och exploatering;

    Sammanfattning : The distributed nature of Federated Learning (FL) creates security-related vulnerabilities including training-time attacks. Recently, it has been shown that well-known Byzantine-resilient aggregation schemes are indeed vulnerable to an informed adversary who has access to the aggregation scheme and updates sent by clients.

  5. 4. Trade-offs in CRISPR Immunity against Mobile Genetic Elements

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Molekylär systembiologi

    Författare :Johanna Cederblad; [2022]
    Nyckelord :CRISPR; microfluidics; fluorescent microscopy; RP4 conjugative plasmid;

    Sammanfattning : The prokaryotic adaptive immune system CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) is a defense mechanism that helps to protect the prokaryotic cell from invading mobile genetic elements. This project was performed at Uppsala University and served to answer whether the expression of Cascade, which is part of the CRISPR defense system, will have a negative effect on the cell that expresses it and to also determine whether the CRISPR defense system is effective enough to stop the spread of a conjugative plasmid.

  7. 5. Text Mining Methods for Biomedical Data Analysis

    Magister-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Rakhshanda Jabeen; [2021]
    Nyckelord :;

    Sammanfattning : Biological data topic modeling has become a very prevalent topic among researchers in recent times. However, analysing countless research papers and gathering consensus regarding biomedicine is a near-impossible task for any researcher due to the complexity and quantity of material that is published.
