2. 1. lac of Time : Transcription Factor Kinetics in Living Cells

   Author : Petter Hammar; Johan Elf; Antoine van Oijen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; gene regulation; transcription factor; lac operon; facilitated diffusion; single molecule imaging; Molecular Biotechnology; Molekylär bioteknik;

   Abstract : Gene regulation mediated by transcription factors (TFs) is essential for all organisms. The functionality of TFs can largely be described by the fraction of time they occupy their regulatory binding sites on the chromosome. DNA-binding proteins have been shown to find their targets through facilitated diffusion in vitro. READ MORE

4. 2. Energy-Centric Scheduling for Real-Time Systems

   Author : Flavius Gruian; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; Computer science; numerical analysis; System-Level Synthesis; Variable Speed Processors; Dynamic Voltage Scaling; Real-Time Scheduling; Energy Efficient Systems; control; systems; system; kontroll;

   Abstract : Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. READ MORE

5. 3. The clinical value of total isovolumic time

   Author : Gani Bajraktari; Michael Henein; Krister Lindmark; Lars-Åke Brodin; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; cardiac resynchronization therapy; predictors; echocardiography; total isovolumic time; six-minute walk test; left ventricular dyssynchrony;

   Abstract : The objective of this thesis is to evaluate the use of Doppler echocardiography markers ofglobal dyssynchrony [total isovolumic time (t-IVT)] in the following 6 studies: 1) Its prognostic role in predicting cardiac events in patients undergoing CABG surgery,compared with conventional global systolic and diastolic measurements. 2) Its additional value in predicting six minute walk test (6-MWT) in patients with leftventricular (LV) ejection fraction (EF) .

6. 4. Repair and Reconstruction of Peripheral Nerve Injuries. Treatment with G-CSF and Stromal Vascular Fraction

   Author : Hanna Frost; Malmö Handkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; peripheral nerve injuries; nerve regeneration; reconstructive surgical procedures; diabetes mellitus; rat sciatic nerve; granulocyte colony-stimulating factor; stromal vascular fraction; electrospinning; rats; Schwann cells;

   Abstract : While surgery is a cornerstone in treatment of peripheral nerve injuries, it is not a comprehensive approach, and outcome is unsatisfactory, especially sensory function. The present aim was to translate recent findings about stem- and progenitor cells to improve regenerative outcome, where the cells have to be autologous, available within the same surgical procedure, and minimally manipulated.

7. 5. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

   Author : Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Abstract : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. READ MORE
