  1. 11. Description and prediction of clinical radiosensitivity : emphasis on normal tissue reactions

    Författare :Roger Tell; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Radiotherapy; radiosensitivity; normal tissue; thyroid; cell cycle; lung injury;

    Sammanfattning : There is a range in the severity of normal tissue reactions observed when cancer patients receive radiotherapy (RT). The limits of dosage in RT have empirically been set by doses that have caused severe reactions in the most sensitive patients. The understanding of factors governing variations of radiosensitivity is therefore very important in RT. LÄS MER

  3. 12. Microelectrode cluster technology for precise interactions with neuronal circuits. Towards highly specific adaptive deep brain stimulation

    Författare :Mohsin Mohammed; Neuronano Research Center (NRC); []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuro-electronic interfaceneural interface; neural interface; tissue reactions; deep brain stimulation; Adaptive DBS; biocompatibility; implantation method; neurosurgical tool;

    Sammanfattning : Neuro-electronic interfaces, which can be used for stable communication between neurons-computers over long periods of time, would be valuable for understanding and interacting with the nervous system. A major challenge has been to overcome the tissue reactions towards implanted electrodes. LÄS MER

  4. 13. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours

    Författare :Sara Pålsson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temperature; perfusion; PDT; photodynamic therapy; mechanisms; tissue characterization; instrumentation; optical biopsy; fluorescence spectroscopy; spectroscopy techniques; Raman spectroscopy; interstitial photodynamic therapy; photodynamic threshold dose; Atomic and molecular physics; Atom- och molekylärfysik;

    Sammanfattning : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. LÄS MER

  5. 14. Verification of high energy photon therapy based on PET/CT imaging of photonuclear reactions

    Författare :Sara Janek Strååt; Anders Brahme; Cathrine Jonsson; Iuliana Dasu; Sibylle Ziegler; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonuclear reactions; PET CT treatment verification; High-energy photon therapy; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : For classical and intensity modulated radiation therapy of deep-seated tumors, high-energy photons are the optimal radiation modality from an integral dose point of view. By using narrow scanned beams the treatment outcome can be improved substantially by delivering biologically optimized intensity modulated distributions often with sharp dose gradients. LÄS MER

  7. 15. Prostasome Modulation of Blood Cascade System and Phosphoprotein Reactions with Focus on Prostate Cancer

    Författare :Adil Abdelgadir Babiker; Kristina Nilsson Ekdahl; Michael Wilson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; ATPase; CD59; Complement; DU145; Extracellular phosphorylation; LNCaP; PC-3; Prostasomes; Prostate cancer; Protein kinases; Tissue factor; Immunologi; Immunology; Immunologi;

    Sammanfattning : Prostasomes are extracellularly occurring submicron, membrane-surrounded organelles produced by the epithelial cells of the prostate and present in semen. Their precise physiological role is not known, although some of their properties assign them to important physiological and patho-physiological functions. LÄS MER
