1. 11. Ventricular rotation and the rotation axis : a new concept in cardiac function

   Författare :Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

   Sammanfattning : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. LÄS MER

3. 12. Matrix degrading proteases in the ovary : expression and function

   Författare :Patrik Wahlberg; Tor Ny; Ilpo Huhtaniemi; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; ovary; ovulation; corpus luteum; plasminogen; PA; MMP; rat; mouse; Biokemi; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : Extracellular matrix degrading proteases from the plasminogen (plg) activator (PA) and the matrix metalloproteinase (MMP) systems have been implicated as important mediators of ovulation and corpus luteum (CL) formation and regression. The aim of this thesis was to investigate the expression and regulation of PAs and MMPs in the ovary and to examine their functional roles for CL formation and function. LÄS MER

4. 13. Modular function deployment

   Författare :Gunnar Erixon; KTH; []
   Nyckelord :;

   Sammanfattning : This thesis introduces a method and procedure for thedevelopment of modular products including a tool for evaluationof modular concepts based on case studies, empirical data foundin test examples and accepted design theories.The method is called Modular Function Deployment (MFD) andconsists of five major steps.

5. 14. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

   Författare :Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

   Sammanfattning : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. LÄS MER

7. 15. Chromatin Remodeling by BRG1 and SNF2H : Biochemistry and Function

   Författare :Patrik Asp; Ann-Kristin Östlund Farrants; Anthony Imbalzano; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chromatin; chromatin remodeling; SWI SNF; ISWI; BRG1; SNF2H; Prp8; RNA; transcription; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : Chromatin is a highly dynamic, regulatory component in the process of transcription, repair, recombination and replication. The BRG1 and SNF2H proteins are ATP-dependent chromatin remodeling proteins that modulate chromatin structure to regulate DNA accessibility for DNA-binding proteins involved in these processes.
