1. 6. Retinoid metabolism and signalling in vascular smooth muscle cells

   Författare :Pauline Ocaya; Allan Sirsjö; Andreas C. Gidlöf; William S. Blaner; Örebro universitet; []
   Nyckelord :all-trans Retinol; all-trans Retinoic acid; retinoid metabolism; proliferation; Vascular smooth muscle cells; CYP26; MEDICINE; MEDICIN; Biomedicin; Biomedicine;

   Sammanfattning : Smooth muscle cells (SMCs) play a major role in cardiovascular diseases. In advanced atherosclerosis, blood flow is impaired due to reduced luminal diameter. Percutaneous vascular interventions, including balloon angioplasty and stent-application are commonly used for the re-establishment of luminal size and improvement of tissue perfusion. LÄS MER

3. 7. Heparin-binding protein and organ failure in critical illness

   Författare :Jonas Tydén; Joakim Johansson; Magnus Hultin; Jakob Walldén; Sören Berg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparin-binding protein; Critical care; Shock; Acute respiratory distress syndrome; Acute kidney injury; Ventilator induced lung injury; Renal clearance; Anaesthesiology; anestesiologi;

   Sammanfattning : Background: For patients severely ill enough to require care in an intensive care unit (ICU), both the disease itself (e.g. bacteria in the blood in sepsis or fractures after trauma) and effects of the immune system can cause circulatory, pulmonary, or renal dysfunction. Leukocytes play a dominant role in the immune system. LÄS MER

4. 8. 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.

5. 9. Development of tissue-equivalent CVD-diamond radiation detectors with small interface effects

   Författare :Bartosz Górka; Bo Nilsson; José M. Fernández-Varea; Anders Brahme; Hugo Palmans; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CVD-diamond detector; tissue-equivalent encapsulation; dosimetry; Monte Carlo simulation; Physics; Fysik; medicinsk strålningsfysik; Medical Radiation Physics;

   Sammanfattning : Due to its close tissue-equivalence, high radiation sensitivity, dose and dose-rate linearity, diamond is a very promising detector for radiation therapy applications. The present thesis focuses on the development of a chemical vapour deposited (CVD) diamond detector with special attention on the arrangement of the electrodes and encapsulation having minimal influence on the measured signal.

7. 10. Myocardial Tissue Characterization Using Magnetic Resonance Imaging

   Författare :Sofia Kvernby; Tino Ebbers; Jan Bertus Marcel Warntjes; Jan Engvall; Agnetha Gustafsson; Per Thunberg; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : In cardiovascular disease, which is the most common cause of death in the world, early diagnosis is crucial for disease outcome. Diagnosis of cardiovascular disease can be challenging, though. LÄS MER
