1. 1. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response

   Författare :Fredrik Qvarnström; Ingela Turesson; Gunilla Enblad; Mats Harms-Ringdahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; γH2AX; 53BP1; checkpoint; p21; apoptosis; mitosis; Oncology; Onkologi; Oncology; onkologi;

   Sammanfattning : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. LÄS MER

3. 2. Tumor instructed normal tissue : studies of potential extratumoral biomarkers and therapeutic targets in prostate cancer

   Författare :Maria Nilsson; Sofia Halin Bergström; Anders Bergh; Kristian Pietras; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; biomarkers; tumor-instructed normal tissue; extra cellular matrix; macrophages; LOX; HO-1; MSMB; Pathology; patologi;

   Sammanfattning : Prostate cancer is the most common cancer in men in Sweden and but luckily the majority of the patients will carry on their life without any consequences from the disease. Unfortunately, some will develop aggressive tumors and eventually die. LÄS MER

4. 3. Quantification of Radiation Induced DNA Damage Response in Normal Skin Exposed in Clinical Settings

   Författare :Martin Simonsson; Ingela Turesson; Gunilla Enblad; Dag Rune Olsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; DNA damage response; low-dose hypersensitivity; dose response; normal tissue; epidermis; dermis; keratinocyte; fractionated radiotherapy; DNA double strand break; DSB; foci; gamma-H2AX; 53BP1; p21; checkpoint; apoptosis; mitosis; micro-RNA; miR-34a; Oncology; Onkologi; Oncology; Onkologi;

   Sammanfattning : The structure, function and accessibility of epidermal skin provide aunique opportunity to study the DNA damage response (DDR) of a normaltissue. The in vivo response can be examined in detail, at a molecularlevel, and further associated to the structural changes, observed at atissue level. LÄS MER

5. 4. Improved dose response modeling for normal tissue damage and therapy optimization

   Författare :Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
   Nyckelord :Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.

7. 5. Tissue Perfusion and Oxygenation Evaluated by Measurements of Tissue Gases and pH. An Experiemental Study

   Författare :Åke Mellström; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intensive care; Anestesiologi; intensivvård; Anaesthesiology; Tissue pH; Tissue PCO2; Oxygen utilization; Tissue PO2;

   Sammanfattning : Optimum peripheral perfusion, oxygenation and oxygen utilization is a prerequisite for normal wound healing, resistance to infection and cardiac function. The purpose of this study was to evaluate peripheral oxygen utilization by measurements of subcutaneous tissue gases and pH (PscO2, PscCO2 and pHsc) in comparison to established techniques for measurements of periph-eral tissue oxygenation and oxygen utilization in experimental animal models with hyperoxia-hypoxia, acidosis-alkalosis and haemorrhage-resuscitation.
