  2. 6. Transcriptional and Epigenetic Regulation of Epithelial-Mesenchymal Transition

    Author : E-Jean Tan; Aristidis Moustakas; Carl-Henrik Heldin; Geert Berx; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGFβ; EMT; HMGA2; Snail; Twist; E-cadherin; epigenetics; invasion; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : The transforming growth factor beta (TGFβ) is a cytokine that regulates a plethora of cellular processes such as cell proliferation, differentiation, migration and apoptosis. TGFβ signals via serine/threonine kinase receptors and activates the Smads to regulate gene expression. READ MORE

  4. 7. Effect of high-temperature drying on spruce and larch Shape stability, mechanical properties and mould growth

    Author : Eva Frühwald; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; twist; shape stability; Norway spruce; mould susceptibility; larch; high-temperature drying; distortion; Technological sciences; Teknik; Material technology; Materiallära; Building construction; materialteknik; heat-treatment; Byggnadsteknik; KSTRWood;

    Abstract : Shape stability, the ability of the wood to retain its shape, is one of the most important parameters when using timber as a building material and for other applications. Generally, timber undergoes changes in dimensions and shape when its moisture content is changed. READ MORE

  5. 8. Moisture-induced Distortion in Norway Spruce Timber - Experiments and Models

    Author : MARIE JOHANSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spiral grain angle; bow; spring; twist; wood; longitudinal shrinkage; crook; warp; compression wood; lumber;

    Abstract : Timber is a natural material that is environmentally friendly, renewable, light, strong and, in the eyes of most people, beautiful. Timber does, however, have one important drawback when it is used in a modern mechanised building process - its lack of straightness. READ MORE

  6. 9. Field Theories with a Twist

    Author : Louise Anderson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Supersymmetry; Supersymmetric Gauge Theory; Topological Field Theories;

    Abstract : This thesis deals with topological field theories derived from maximally supersymmetric gauge theories. The main part of this work is the three appended research papers, each of which investigates some different aspect of these theories. READ MORE

  7. 10. Effect of valve replacement for aortic stenosis on ventricular function

    Author : Ying Zhao; Michael Henein; Per Lindqvist; Eugenio Picano; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; aortic valve replacement; echocardiography; speckle tracking; exercise echocardiography; ventricular function; septal radial motion; twist; displacement; strain; strain rate;

    Abstract : Background：Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. READ MORE
