1. 1. Early Blood Cell Formation "in sickness and health, ´till death do us part"

   Författare :Kees-Jan Pronk; Immunologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic stem cell; differentiation; regulation; myeloerythropoeisis; myelopoesis; p16INK4A; aging; tumor necrosis factor;

   Sammanfattning : Hematopoietic stem cells (HSC), the ancestors of all blood cells, have the ability to give rise to mature effector cells through a series of developmental steps. This is a tightly regulated, though a highly dynamic process: on the one hand, dysregulation in steady-state could lead to under- or overgrowth of certain blood cell lineages, whereas, on the other hand, demands for certain mature blood cells can change dramatically in cases like bleeding and infections.

3. 2. Interactions between whole blood and TiO₂ surfaces with focus on adhesion and activation of PMN granulocytes

   Författare :Cecilia Eriksson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; titanium; TiO2; surface roughness; oxide thickness; wettability; whole blood; inflammation; wound healing; platelets; PMN granulocytes; adhesion; activation; receptor expression; respiratory burst.;

   Sammanfattning : Foreign materials come in contact with the human body more and more frequently. The surgical procedure of inserting an implant into the body will cause bleeding, evoke an inflammatory response and initiate a healing process, ultimately leading to acceptance or rejection of the material.

4. 3. Clinical Aspects of Bleeding and Transfusion in Cardiac Surgery

   Författare :Lisa Ternström; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; bleeding; fibrinogen; blood transfusion; transfusion guidelines; adherence;

   Sammanfattning : Abstract Excessive bleeding after cardiac surgery is a serious complication that is associated with increased morbidity and mortality. The bleeding is multifactorial and influenced by both surgical factors and impaired haemostasis. LÄS MER

5. 4. The use of fibrinogen in cardiac surgery patients-clinical and experimental studies

   Författare :Katarina Waldén; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fibrinogen; cardiac surgery; bleeding; transfusion; thromboembolism; tranexamic acid;

   Sammanfattning : BACKGROUND Cardiac surgery with cardiopulmonary bypass impairs hemostasis due to hemodilution and consumption of platelets and coagulation factors, such as fibrinogen. The aim of this thesis was to study the role of fibrinogen in bleeding complications in cardiac surgery patients. LÄS MER

7. 5. Aspects on bleeding and transfusion in elective orthopaedic surgery. Clinical and experimental studies

   Författare :Malin S Carling; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedic surgery; fibrinogen; factor XIII; surgical bleeding; transfusion;

   Sammanfattning : Background: Perioperative bleeding complications are associated with increased morbidity and mortality. One way to minimize perioperative bleeding and transfusion is to identify patients at risk of bleeding. Preoperative fibrinogen plasma concentration and factor XIII (FXIII) activity may be indicators of perioperative bleeding and transfusion. LÄS MER
