1. 1. Hypoxic gene regulation and oncogenic pathways in neuroblastoma

   Författare :Erik Fredlund; Institutionen för translationell medicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microarray; hypoxia; MYCN; gene expression analysis; Neuroblastoma; Myc; pathway analysis; differentiation;

   Sammanfattning : Neuroblastoma patients show remarkable clinical heterogeneity, with courses ranging from spontaneous regression to fatal tumor progression despite intense multi-modal treatment. Previous studies have shown that hypoxia pushes neuroblastoma cells towards a more immature phenotype, which correlates to aggressive disease. LÄS MER

4. 3. Using a Social Semiotic Perspective to Inform the Teaching and Learning of Physics

   Författare :Tobias Fredlund; Cedric Linder; David Wolfe; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Social semiotics; semiotic resources; physics education research; interactive engagement; disciplinary affordance; disciplinary-relevant aspects; patterns of disciplinary-relevant aspects; the Variation Theory of Learning; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Sammanfattning : This thesis examines meaning-making in three different areas of undergraduate physics: the refraction of light; electric circuits; and, electric potential and electric potential energy. In order to do this, a social semiotic perspective was constituted for the thesis to facilitate the analysis of meaning-making in terms of the semiotic resources that are typically used in the teaching and learning of physics.

5. 4. Adolescents Selling Sex and Sex as Self-Injury

   Författare :Cecilia Fredlund; Marie Wadsby; Carl Göran Svedin; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adolescents; Selling sex; Sex as self-injury; Child sexual exploitation; Sexual abuse;

   Sammanfattning : There are today only a few population-based studies in the world investigating the prevalence of and associated risk-factors with adolescents selling sex and so far no earlier population-based study has been found investigating adolescents motives for selling sex. Further, to use sex in means of self-injury (SASI) is a behaviour that has been highlighted in Sweden the last years but it is a new field of research and a behaviour in need of conceptualization.

7. 5. Inhibition of Calcium and Zinc Absorption by Phytate in Man Methodological Studies and Hydrothermal Processing of Cereals to Improve Absorption

   Författare :Kerstin Fredlund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; barley; wheat; rye; 65Zn; oats; zinc absorption; whole grains; InsP6; hydrothermal processing; calcium absorption; rice; radionuclide technique; 47Ca; extrinsic labelling; phytate; hydrothermal treatment; myo-inositol; calcium retention; whole-body counting;

   Sammanfattning : A mathematical model based on measurements in a whole-body counter described the retention of calcium in the human body. It was shown that the relative retention of intravenous and orally administered 47Ca in all subjects (n = 10 - 11) were well described by fitting a simple function of time with two free parameters to a few whole-body measurements after day 6, when the unabsorbed calcium had been excreted.
