1. 1. Bone Regeneration with Cell-free Injectable Scaffolds

   Författare :Gry Hulsart Billström; Sune Larsson; Kenneth B Jonsson; Jöns Hilborn; Håkan Engqvist; Olle Svensson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bone tissue engineering; hydrogel; computed tomography; positron emission tomography; large femoral bone defect; rat model; hydrogel; in vivo; osteogenesis; bone regeneration; 3R; single-photon emission computed tomography; bone morphogenetic protein 2; calcium phosphates; injectable; bisphosphonate;

   Sammanfattning : Bone is a remarkable multifunctional tissue with the ability to regenerate and remodel without generating any scar tissue. However, bone loss due to injury or diseases can be a great challenge and affect the patient significantly. Autologous bone grafting is commonly used throughout the world. LÄS MER

4. 3. Activity quantification based on scintillation camera imaging - Application to 111In/90Y radioimmunotherapy

   Författare :David Minarik; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; bremsstrahlung imaging; activity quantification; SPECT; conjugate view; Yttrium;

   Sammanfattning : Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. LÄS MER

5. 4. Leukocyte scintigraphy, SPECT/CT and PET/CT in prosthetic joint infection

   Författare :Johan Teiler; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: A known complication of arthroplasty is prosthetic joint infection (PJI). It can be challenging to diagnose and treat PJI due to the formation of a biofilm protecting the bacteria in chronic infections from the innate immune system and antibiotics. LÄS MER

7. 5. Small-scale dosimetry methods for normal tissues after radioembolization and peptide receptor radiotherapies; a focus on the liver parenchyma and the bone marrow

   Författare :Jens Hemmingsson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dosimetry; Radioembolization; PRRT; lutetium-177; terbium-161; yttrium-90;

   Sammanfattning : Radionuclide therapies are increasingly used in cancer treatments as they have been proven to be both effective and safe. As biodistributions and uptake vary widely between patients, a standardized approach is bound to leave a fraction of patients overtreated or undertreated. LÄS MER
