1. 11. Heat shock proteins as vaccine adjuvants

   Författare :Khaleda Rahman Qazi; Carmen Fernández; Qijun Chen; Stockholms universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heat shock protein; vaccine; adjuvant; BCG; Immunology; Immunologi;

   Sammanfattning : New efficient vaccines against infectious diseases are in demand. Some important factors impeding the vaccine development are the poor immunogenicity and the MHC restriction of the immune responses to a number of antigens. LÄS MER

3. 12. Numerical and Experimental study of shock boundary layer interaction in unsteady transonic flow

   Författare :Olivier Bron; KTH; []
   Nyckelord :Shock Boundary Layer Interaction; Shock Motion; Unsteady Flows; Nozzle Flows; Potential Interaction; Back Pressure Perturbations;

   Sammanfattning : A prerequisite for aeroelastic stability prediction inturbomachines is the understanding of the fluctuatingaerodynamic forces acting on the blades. Unsteady transonicflows are complex because of mutual interactions betweentravelling pressure waves, outlet disturbances, shock motion,and fluctuating turbulent boundary layers. LÄS MER

4. 13. Strain echocardiography in the critically ill patient : Studies in patients with septic shock and subarachnoid haemorrhage

   Författare :Keti Dalla; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Strain echocardiography in ICU patients; Left ventricle; Right ventricle; Septic shock; Subarachnoid haemorrhage; Norepinephrine;

   Sammanfattning : In this thesis, strain echocardiography by two-dimensional speckle tracking imaging (2D-STI), was used for the evaluation of left ventricular (LV) and right ventricular (RV) function in critically ill patients with septic shock and subarachnoid haemorrhage. The aims were to: 1) investigate the value of strain echocardiography for the early detection of LV and RV dysfunction not diagnosed with conventional echocardiography in severe sepsis and septic shock, 2) to study the effects of norepinephrine on RV systolic function and pulmonary haemodynamics in patients with norepinephrine-dependent septic shock 3) evaluate the use of strain echocardiography for detection of myocardial injury in patients with subarachnoid haemorrhage (SAH) and 4) study the impact of general anaesthesia and positive pressure ventilation (PPV) on RV and LV myocardial longitudinal strain.

5. 14. C5a Receptor Expression in Severe Sepsis and Septic Shock

   Författare :Mia Furebring; Jan Sjölin; Per Folllin; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; C5a receptor; granulocyte; severe sepsis; septic shock; chemotaxis; anti-C5a treatment; ex vivo incubation; C5a; interleukin-8; LPS; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar;

   Sammanfattning : In patients with sepsis, the activation of the cascade systems, for example the complement system with the generation of C5a, is followed by a state of immunosuppression with impaired bactericidal capacity caused by suppression of the neutrophil granulocytes. To inhibit the C5a-induced systemic inflammatory and the following anti-inflammatory responses, different anti-C5a strategies have been successful in experimental models of sepsis. LÄS MER

7. 15. Cardiac dysfunction in septic shock : Observational studies on characteristics and outcome

   Författare :Lina De Geer; Christina Eintrei; Anna Oscarsson Tibblin; Jan Engvall; Else Tønnesen; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Background: Cardiac dysfunction is a well-known complication of sepsis, but its characteristics and consequences, especially on a longer term, remain unclear. The aim of this thesis was to study the characteristics and the implications of cardiac dysfunction for outcome in intensive care unit (ICU) patients with septic shock. LÄS MER
