1. 1. Balance performance in people with Parkinson’s disease. Effects of subthalamic Deep Brain Stimulation

   Författare :Maria H Nilsson; Aktivt och hälsosamt åldrande; []
   Nyckelord :Parkinson s disease; Deep Brain Stimulation; subthalamic nucleus; balance; falls.; fear of falling;

   Sammanfattning : The overall aims of this work were to investigate if Deep Brain Stimulation in the subthalamic nuclei (STN) affected balance, fear of falling and falls in people with Parkinson's disease. The effect of STN stimulation alone was investigated in Papers I, II and III. LÄS MER

3. 2. Escape to space or return to venus : ion flows measured by venus express

   Författare :Moa Persson; Yoshifumi Futaana; Hans Nilsson; Maria Hamrin; Dmitrij Titov; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Venus; water; escape; planetary physics; oxygen; O ; hydrogen; H ; ions; space physics; space plasma physics; Venus Express; ASPERA-4; IMA; spacecraft measurements; rymd- och plasmafysik; Space and Plasma Physics;

   Sammanfattning : The present-day Venusian atmosphere is crushingly dense, extremely hot and arid. Yet, in its early history, Venus presumably had a massive amount of water, which, if spread evenly over the surface, provided a water depth of 10s to 100s of meters. Therefore, over the course of the atmospheric evolution, the water must have been removed from Venus. LÄS MER

4. 3. Interactions between Streptococcus pyogenes and the human immune defence

   Författare :Maria E Nilsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; M protein; Streptococcus pyogenes; Streptolysin O; The complement system; Neutrophils; Biomedical sciences; Biomedicinska vetenskaper; General biomedical sciences; Biomedicinska vetenskaper allmänt ; Microbiology; transplantation; Immunology; serology; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; Immunologi; serologi; Infections; Infektioner; Clinical biology; Klinisk biologi; bacteriology;

   Sammanfattning : Streptococcus pyogenes is an important human pathogen frequently colonizing the throat and skin of humans. To facilitate colonization and spread and to avoid the host immune defence, streptococci are endowed with a variety of virulence factors, two of which are investigated in this thesis namely streptolysin O (SLO) and M protein.

5. 4. Studies of Innate and Adaptive Immunity in Islet Transplantation

   Författare :Maria Hårdstedt; Olle Korsgren; Bo Nilsson; Thierry Berney; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; islet transplantation; islets of Langerhans; xenotransplantation; nonhuman primate; blood; whole blood model; innate immunity; adaptive immunity; IBMIR; chemokines;

   Sammanfattning : Clinical islet transplantation is today an established alternative treatment for a selected group of type 1 diabetes patients. The predominant technique for transplantation is infusion of islets in the liver via the portal vein. LÄS MER

7. 5. Studies of The Electronic Structure of CuPc and PTCDA - Two Molecular Organic Semiconductors

   Författare :Maria Nilsson Tengelin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PTCDA; ITO; UPS; Organic Semiconductor; XPS; CuPc;

   Sammanfattning : Since the discovery of organic materials with conducting and semiconducting proper¬ties a few decades ago, the research in this field has intensified and has become in¬creasingly important. Expected advantages of both economical and technological nature have been powerful driving forces in this development, and today organic based devices are becoming a reality for commercial applications.
