1. 21. Hypoxia, PDGF and VEGF in Vascular Development

   Författare :Ingrid Nilsson; Lena Claesson-Welsh; Randall Johnson; Uppsala universitet; []
   Nyckelord :Cell biology; hypoxia; VEGF; VEGFR-3; PDGF; endothelial cell; embryonic stem cell; angiogenesis; lymphangiogenesis; Cellbiologi;

   Sammanfattning : The mechanisms behind many important aspects of blood- and lymphatic vessel formation have yet not been elucidated in detail. The primary objectives of this thesis have therefore been to study the effects of hypoxia, platelet-derived growth factor (PDGF) and vascular endothelial growth factors (VEGFs) on vascular development and function.

4. 23. Opioidberoende : en studie om beroendevården och det sociala sammanhangets betydelse

   Författare :Marcus Nilsson Blom; Björn Blom; Mojgan Padyab; Daniel Törnqvist; Lena Lundgren; Björn Johnson; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Opioid dependence; medication assisted treatment; compulsory care; social cohesion; register-based research; social work;

   Sammanfattning : Opioid dependence is highly associated with health problems relating to physical health (infectious diseases) as well as mental health (depression, anxiety, antisocial behavior). In addition, research has found an association between use of opioids and increased risk of premature death as a consequence of overdose or other circumstances, such as suicide. LÄS MER

5. 24. Effects of sex steroids and tamoxifen on matrix metalloproteinase activity and generation of endostatin in the breast

   Författare :Ulrika W. Nilsson; Charlotta Dabrosin; Lena Claesson-Welsh; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Breast cancer; TGF-β1; Endostatin; Estradiol; Mammary gland; Matrix metalloproteinases; MCF-7; Microdialysis; Nude mice; Tamoxifen; Oncology; Onkologi;

   Sammanfattning : Sex steroids are inevitable in women. However, long-term exposure to sex steroids increases the risk of breast cancer. A complete understanding of sex steroid control of the breast and how it relates to breast cancer risk is still lacking. LÄS MER

7. 25. Degradation Mechanisms of Heat Resistant Steel at Elevated Temperatures : In an Iron Ore Pelletizing Industry

   Författare :Erik A. A. Nilsson; Marta-Lena Antti; Ragnar Tegman; Jan-Erik Svensson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; Grate-Kiln; microstructure; corrosion; as-casted; thermal cycling; erosion; deposition; Engineering Materials; Materialteknik;

   Sammanfattning : This thesis focuses on the different degradation mechanisms of the stainless steel in a travelling grate in a Grate-Kiln iron ore pellet indurator. The travelling grate is a conveyor belt that transports green-body pellets to a rotary kiln while the pellets are being dried and pre-heated to a temperature of 900-1100 °C by recycled hot air.
