  1. 1. Abdominal aortic aneurysm inception and evolution - A computational model

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andrii Grytsan; KTH.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aorta; Aneurysm; AAA; Blood Flow; Wall Shear Stress; Growth and Remodeling; Mixture Model; Growth Kinematics; Fluid-Solid-Growth; Aorta; Aneurysm; AAA; Blodflöde; Vägg Skjuvspänning; Tillväxt och Strukturförändring; Blandning Modell; Tillväxt Kinematik; Teknisk mekanik; Engineering Mechanics;

    Abstract : Abdominal aortic aneurysm (AAA) is characterized by a bulge in the abdominal aorta. AAA development is mostly asymptomatic, but such a bulge may suddenly rupture, which is associated with a high mortality rate. Unfortunately, there is no medication that can prevent AAA from expanding or rupturing. READ MORE

  2. 2. Abdominal Aortic Aneurysm Molecular Imaging Studies of Pathophysiology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gustaf Tegler; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Abdominal aortic aneurysm; AAA; Positron emission tomography; PET; Molecular Imaging; Pathophysiology; Autoradiography; Angiogenesis; integrin alphaVbeta3; FDG; 18F-FDG; 11C-PK11195; 11C-D-deprenyl; [18F]fluciclatide; Fluciclatide; Bukaortaaneurysm; Molekylär bilddiagnostik; Patofysiologi; PET; Autoradiografi; Angiogenes; Kirurgi; Surgery; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : The pathological process behind abdominal aortic aneurysm (AAA) formation is poorly understood and difficult to study. The aim of the thesis was to study the pathophysiology of AAA formation with positron emission tomography (PET) technology, a molecular imaging technique, allowing in vivo studies of pathophysiological changes.

  3. 3. Vascular remodelling and circulating basement membrane fragments in abdominal aortic aneurysm

    University dissertation from Umeå : Umeå Universitet

    Author : Mari Holsti; Umeå universitet.; [2019]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AAA; extracellular matrix; vascular remodelling; collagen; inflammation; Surgery; kirurgi;

    Abstract : An abdominal aortic aneurysm (AAA) is a degenerative disease, characterized by advanced inflammation and extracellular matrix (ECM) remodelling. Enhanced protease activity mediated by cytokines results in the degradation of ECM proteins, leading to the generation of different bioactive fragments. READ MORE

  4. 4. Actions of androgens and estrogens in experimental models of cardiovascular disease

    University dissertation from Göteborg : University of Gothenburg

    Author : Johan Bourghardt Fagman; Göteborgs universitet.; Gothenburg University.; [2010]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AR; atherosclerosis; AAA; androgens; testosterone; 2-methoxyestradiol;

    Abstract : Men are at higher risk of developing both atherosclerotic cardiovascular disease and abdominal aortic aneurysm (AAA). Actions of sex steroids are hypothesized to underlie these gender differences. Testosterone, the major androgen, reduces atherosclerosis in male animal models but is suggested to promote AAA formation. READ MORE

  5. 5. Structure and mechanism of iron and magnesium chelatases - at the heme-chlorophyll branch-point

    University dissertation from Molecular Biophysics, Lund University

    Author : Michel Fodje; Lunds universitet.; Lund University.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biophysics; pi-helix; secondary structure; AAA; porphyrin metallation; chelatase; Molekylär biofysik;

    Abstract : Tetrapyrroles are synthesised through a single branched biosynthetic pathway. Heme and chlorophyll are synthesised from the common intermediate protoporphyrin IX at the heme-chlorophyll branch-point. READ MORE
