  1. 16. Methodological studies of eicosanoid enzyme gene expression in vascular endothelium exposed to biomechanical stress

    Författare :Roya Doroudi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prostanoids; endothelium; quantitative RT-PCR; perfusion model; shear stress; intraluminal pressure; immediate-early genes;

    Sammanfattning : Prostaglandins are the major eicosanoids synthesized by vascular endothelial cells, and the vasculature is an important target organ for their bioactive metabolites. In vitro studies have shown that biomechanical forces are important regulators of vascular expression of prostanoid enzymes and release of metabolites. LÄS MER

  3. 17. Esophageal- and Gastroesophageal Junctional Cancer : Aspects on Staging, Treatment and Results

    Författare :Gustav Linder; Jakob Hedberg; Magnus Sundbom; Wilhelm Graf; Bas P.L. Wijnhoven; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal cancer; Education level; Tonometry; Lymphadenectomy; PET MRI; Kirurgi; Surgery;

    Sammanfattning : Esophageal- and gastroesophageal junctional (GEJ) cancer is the sixth cause of cancer-related death worldwide. Some improvements in care are attributed to nationwide disease-specific registries, preoperative staging and increased understanding of mechanisms affecting patient selection. LÄS MER

  4. 18. Oesophageal Resection with Gastric Tube Reconstruction - A clinical study of a surgical method and its consequences on the upper gastrointestinal tract and survival

    Författare :Jan Johansson; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Barrett s oesophagus; Survival; Age; Follow-up studies; Physiological studies; Anastomoses; Oesophagectomy; Oesophageal neoplasms; traumatologi; Kirurgi; ortopedi; traumatology; orthopaedics;

    Sammanfattning : In a prospective randomised study following oesophagectomy and gastric tube reconstruction patients with hand-sutured neck anastomoses were compared with patients with circular stapled chest anastomoses. The two groups had equal rates of anastomotic or conduit leaks of 7.3 % (3/41) and 7.1 % (3/42) and of benign anastomotic strictures of 19. LÄS MER

  5. 19. Dynamic Modelling of Physical Processes in Magmatic Systems: Dyke Emplacement and Flow-Induced Crystal Rotations

    Författare :Rémi Vachon; Christoph F. Hieronymus; Janine Kavanagh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical solutions; elasticity and anelesticity; fracturing; magmatic plumbing system; sheet-like intrusions; rheology of the crust; physics of magma; solid mechanics; fluid flow; crystal rotation;

    Sammanfattning : The main motivation for this thesis is to develop and improve numerical tools and methods that help further our comprehension of the volcanic plumbing system and its dynamics.The commonly used standard elastic model predicts solutions of dyke shape, thickness, over-pressure and fracturing criteria that do not always fit natural observations.

  7. 20. Atrial function and loading conditions in athletes

    Författare :Flavio D'Ascenzi; Michael Henein; Sergio Mondillo; Roxy Senior; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; athlete s heart; training; exercise; speckle-tracking echocardiography; atrial strain; atrial deformation; Cardiology; kardiologi;

    Sammanfattning : Intensive training is associated with hemodynamic changes that typically induce an enlargement of cardiac chamber. Despite LA dilatation in athletes has been interpreted as a benign adaptation, little evidence is available. LÄS MER
