1. 1. Hepatocyte growth factor : Studies on local and systemic release and effects during infectious disease; in vivo and in vitro

   Författare :Fariba Nayeri; Minoca Niste'r; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The interaction of mesenchymal and epithelial cells that occurs after organ injuries results in enhanced production of cytokines, such as hepatocyte growth factor (HGF). HGF is a glycoprotein with unique properties that contribute to wound healing after injuries. LÄS MER

3. 2. Jakten på koncentration - Från teori till idrott

   Författare :John Jansson; Bo Molander; Ingemar Weman; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Concentration; attention; Test of Attentional and Interpersonal Style TAIS ; ironic processing; sport psychology; ; Psychology; Psykologi;

   Sammanfattning : When athletes and coaches discuss reasons for success or failure the word concentration has an important role. Likewise, in sport research, the term attention tends to have the same central position. This notion gives the impression that everyone seems to know what concentration is and how it affects sport performances. LÄS MER

4. 3. Empirical essays on Regional Specialization and Trade in Sweden

   Författare :Hanna Norberg; Nationalekonomiska institutionen; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; market size; scale economies; technological differences; factor-proportions; Regional production; trade; concentration.; International commerce; Internationell ekonomi;

   Sammanfattning : This thesis deals with the empirical testing of trade theories, traditionally used to analyze international trade, using regional data on production and trade. This thesis consists of three main essays. In the first essay, we analyze Swedish regional production. LÄS MER

5. 4. The hematopoietic transcription factor RUNX1 : a structural view

   Författare :Stefan Bäckström; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; RUNX1; Runt domain; CBFβ; transcription factor; leukaemia; protein crystallography; anomalous diffraction; Molekylärmedicin; Molecular medicine genetics and pathology ; Molekylär medicin genetik och patologi ; molekylärbiologi; Molecular Biology;

   Sammanfattning : The malfunction of the transcriptional regulator RUNX1 is the major cause of several variants of acute human leukemias and its normal function is to regulate the development of the blood system in concert with other transcriptional co-regulators. RUNX1 belongs to a conserved family of heterodimeric transcription factors that share a conserved DNA binding domain, the Runt domain (RD), named after the first member of this group – Runt - found in Drosophila melanogaster.
