  1. 1. Search for doubly charged Higgs bosons in multi-lepton final states with the ATLAS detector

    Författare :Katja Mankinen; Partikelfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATLAS; Beyond the Standard Model; Doubly Charged Higgs; Left-right symmetry; LHC; Same-charge leptons; Taus; Transition radiation tracker; Fysicumarkivet A:2020:Mankinen;

    Sammanfattning : Standard Model events with prompt, isolated, same-charge high-pT leptons are rare, and therefore events with such final states provide a powerful signature towards new discoveries. This thesis presents two searches for doubly charged Higgs bosons decaying into same-charge lepton pairs using proton–proton collision data recorded by the ATLAS detector at the LHC. LÄS MER

  2. 2. Intercellular protein transfer and regulation of inhibitory NK receptor accessibility

    Författare :Katja Andersson; Karolinska Institutet; Karolinska Institutet; []

    Sammanfattning : NK cells are important players of innate immunity and capable of promoting specific responses of the adaptive immune system. NK cells possess the ability to recognise and eliminate virus-infected cells, tumour cells and allogeneic bone marrow grafts. LÄS MER

  4. 4. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

    Författare :Katja Bernfur; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

    Sammanfattning : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. LÄS MER

  5. 5. Medical interventions and gastric cancer risk : An observational approach

    Författare :Katja Fall; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Gastric cancer; cardia cancer; histological subtypes; H. pylori; antibiotic treatment; eradication; aspirin; NSAIDs; cholecystectomy; reactive gastritis; cohort; epidemiology;

    Sammanfattning : Helicobacter pylori infection is undoubtedly the most important risk factor for gastric cancer. A causal relationship with gastric cancer, however, has not been clearly established and the carcinogenic mechanism is still ambiguous. LÄS MER
