1. 1. Transcriptional and post-transcriptional regulation of vascular smooth muscle cell phenotype - Implications for vascular disease states

   Författare :Azra Alajbegovic; Molekylär kärlfysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vascular smooth muscle cells VSMC ; cell phenotype; microRNA; Aneurysm; hypertension; Actin polymerization; GATA6; MRTFA; Vascular disease;

   Sammanfattning : As the world population is pushing toward 8 billion, cardiovascular diseases (CVD) remain the leading cause of death worldwide, representing 30% of all global deaths. A large body of work has recognized that smooth muscle cells (SMCs) surrounding the blood vessels play a prominent role in the development and progression of cardiovascular diseases. LÄS MER

3. 2. Giant cell arteritis. Epidemiological, morphological and molecular genetic studies

   Författare :Vigdís Pétursdóttir; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giant cell arteritis; temporal artery; aorta; epidemiology; atrophy; calcification; estrogen receptor a; morphometry; immunocytochemistry; Western blot; molecular genetics;

   Sammanfattning : Giant cell arteritis (GCA) is a chronic inflammatory disorder of unknown etiology, affecting large and medium-sized arteries, predominantly in postmenopausal women. Its pathogenesis is probably multifactorial. Several studies suggest that GCA is an antigen-driven disease. LÄS MER

5. 4. The cell wall ultrastructure of wood fibres : effects of the chemical pulp fibre line

   Författare :Jesper Fahlén; Ulf W. Gedde; Drek G. Gray; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; atomic force microscopy; cellulose; cell wall; drying; fiber; Kemiteknik; Chemical engineering; Kemiteknik;

   Sammanfattning : Knowledge of the ultrastructural arrangement within wood fibres is important for understanding the mechanical properties of the fibres themselves, as well as for understanding and controlling the ultrastructural changes that occur during pulp processing. The object of this work was to explore the use of atomic force microscopy (AFM) in studies of the cell wall ultrastructure and to see how this structure is affected in the kraft pulp fibre line.

7. 5. Understanding and manipulating primary cell walls in plant cell suspension cultures

   Författare :Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
   Nyckelord :Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

   Sammanfattning : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. LÄS MER
