  1. 1. Design and Evaluation of Radiolabeled Affibody Tracers for Imaging of HER2-expressing Tumors

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Helena Wållberg; KTH.; [2011]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Affibody molecule; radionuclide molecular imaging; HER2; radiotracer; SPECT; PET; biodistribution; protein engineering; radiolabeling;

    Sammanfattning : The growing understanding of tumor biology and the identification of tumor specificgenetic and molecular alterations, such as the overexpression of human epidermal growthfactor receptor 2 (HER2), opens up for personalization of patient management using targeted therapies. However, this puts stringent demands on the diagnostic tools usedto identify patients that are likely to respond to a particular treatment. LÄS MER

  2. 2. Small bowel obstruction and toxicity of a new model of adhesion prevention

    Detta är en avhandling från Surgery (Lund)

    Författare :Karolin Isaksson; Lund University.; Lunds universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; small bowel obstruction; predictive parameters; appendectomy; open versus laparoscopic; abdominal adhesions; prevention; polypeptides; toxicity; biodistribution;

    Sammanfattning : Abstract Background: Small bowel obstruction (SBO) is a common surgical diagnosis. If no signs of strangulation are evident, the majority of the patients can be conservatively managed. Approximately one third of the patients need surgical treatment and there is a need for early parameters that can predict operative intervention. LÄS MER

  3. 3. On the Design of Affibody Molecules for Radiolabeling and In Vivo Molecular Imaging

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Daniel Rosik; KTH.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Affibody molecule; AC DC; radionuclide molecular imaging; HER2; SPECT; PET; biodistribution; peptide synthesis; radiolabeling; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : Affibody molecules have lately shown great potential as tools for in vivo molecular imaging. These small, 3-helical bundles, with their highly stable protein scaffold, are well suited for the often harsh conditions of radiolabeling. LÄS MER

  4. 4. Synthesis of Polymeric Nanocomposites for Drug Delivery and Bioimaging

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Heba Asem; KTH.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biodegradable polymers; SPION; QDs; drug delivery; cytotoxicity; MRI; in vivo fluorescence imaging; biodistribution; Physics; Fysik;

    Sammanfattning : Nanomaterials have gained great attention for biomedical applications due to their extraordinary physico-chemical and biological properties. The current dissertation presents the design and development of multifunctional nanoparticles for molecular imaging and controlled drug delivery applications which include biodegradable polymeric nanoparticles, superparamagnetic iron oxide nanoparticles (SPION)/polymeric nanocomposite for magnetic resonance imaging (MRI) and drug delivery, manganese-doped zinc sulfide (Mn:ZnS) quantum dots (QDs)/ SPION/ polymeric nanocomposites for fluorescence imaging, MRI and drug delivery.

  5. 5. Small-Scale Dosimetry for the Testis: Applications in Nuclear Medicine Diagnostics and Therapy

    Detta är en avhandling från Medical Radiation Physics, Lund University

    Författare :Suaad Meerkhan; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2014]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Testis; 111-In; Autoradiography; Biodistribution; Small-Scale; Monte Carlo; Dosimetry; spermatogonia; gammaH2AX; immunofluorescence;

    Sammanfattning : It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution and a resulting non-uniform absorbed-dose distribution.
