1. 6. A close-up on neutrophils : Visualizing the mechanisms of their in vivo recruitment and function

   Författare :Sara Massena; Mia Phillipson; Randall S. Jonhson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; chemokine; chemotactic gradient; citrullination; hypoxia; inflammation; intraluminal crawling; intravital imaging; PAD enzymes; permeability; proangiogenic; proinflammatory;

   Sammanfattning : A successful immune response depends on prompt and sufficient recruitment of leukocytes from the circulation to infected or injured sites. Mobilization of leukocytes to hypoxic tissues is vital for angiogenesis, i.e. the formation of new blood vessels from preexisting vasculature, and thus crucial for tissue growth and regeneration.

3. 7. Intestinal transplantation. Experimental and clinical studies

   Författare :Mihai Oltean; Göteborgs universitet; []
   Nyckelord :Intestinal preservation; Ischemia-reperfusion injury; Tight junction; FK506; Resistin;

   Sammanfattning : Intestinal preservation-reperfusion injury may result in various degrees of mucosal injury. Interestingly, the preservation injury is similar when using the current preservation solutions, which are given as a intravascular flush. An extensive mucosal injury may ultimately preclude the use of organs that require longer preservation time. LÄS MER

4. 8. Regulation of vascular function by fluid mechanical forces. Development of a new vascular experimental platform for integrative physiological and molecular biological studies of living conduit vessels

   Författare :Li-Ming Gan; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; perfusion model; endothelium; smooth muscle cells; shear stress; pressure; nitric oxide; endothelin-1; vascular endothelial growth factor; c-jun; c-fos; real-time PCR; NO probe.;

   Sammanfattning : The vascular endothelium is a multifunctional interface between blood flow and target organs and is continuously exposed to fluid mechanical forces such as shear stress, compressive, and tensile forces. Both in vivo and in vitro data indicate that biomechanical forces exert important modulating effects on key vascular functions. LÄS MER

5. 9. Rectal washout in rectal cancer surgery

   Författare :Rebecca Svensson Neufert; Malmö Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rectal washout; Rectal cancer surgery; Local recurrence; Anterior resection; abdominoperineal resection; Transanal total mesorectal excision;

   Sammanfattning : BackgroundRectal washout (RW) is performed to eliminate intraluminal cancer cells and thereby reducing the risk of local recurrence (LR). The overall aim of this thesis was to investigate the importance of RW in rectal cancer surgery.MethodPaper I: Survey of the current practice of RW among Swedish colorectal units. LÄS MER

7. 10. Cellular and molecular mechanisms in abdominal aortic aneurysm growth and rapture

   Författare :Monsur Kazi; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :AAA; thrombus; proteases; NGAL; mast cells;

   Sammanfattning : Fragmentation of elastin, loss of smooth muscle cells (SMCs) and accumulation of inflammatory cells are the histological landmarks of abdominal aortic aneurysm (AAA). In larger aneurysms, an intraluminal thrombus is almost always present. It has been suggested that the thrombus predisposes for AAA rupture. LÄS MER
