2. 1. Intestinal ischemia and reperfusion. Proinflammatory response and organ dysfunction

   Author : Knut Olanders; Lund Institutionen för kliniska vetenskaper; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatology; Kirurgi; ortopedi; traumatologi; orthopaedics; Surgery; inflammation; cytokine; leukocyte; reperfusion; ischemia; permeability; Intestine; endothelium;

   Abstract : Intestinal I/R is considered to be an important initiating event in several pathophysiological conditions such as trauma, bleeding, sepsis and pancreatitis, frequently leading to concomitant both single and potentially multiple organ dysfunction. The purpose of this thesis was to study mechanims underlying the development of multiple organ dysfunction, with special focus on intercellular proinflammatory regulation in the concurrent development of tissue injury.

4. 2. Improved bioenergetic recovery during experimental ischemia and reperfusion by irradiation

   Author : Ann Lindgård; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : energy metabolism; skeletal muscle; monocyte; ischemia; reperfusion; NMR; singlet oxygen energy; light; LED;

   Abstract : Prolonged ischemia and reperfusion frequently occur during clinical operations. The bioenergetic status decreases during ischemia and reactive oxygen species (ROS) are formed during reperfusion, which may lead to irreversible tissue injury. READ MORE

5. 3. Energy metabolism in skeletal muscle during ischemia and reperfusion. Experimental and clinical aspects

   Author : Jonas Lundberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Keywords : energy metabolism; skeletal muscle; ischemia; reperfusion; MRS; hypothermia; singlet oxygen energy.;

   Abstract : Microsurgical operations, using free vascularised transfer of tissues, induce an obligatory period of ischemia followed by reperfusion. The degree of ischemia and reperfusion injury is dependent on the ischemia time. READ MORE

6. 4. Renal Ischemia/Reperfusion Injury in Diabetes : Experimental Studies in the Rat

   Author : Jan Melin; Bengt Rippe; Uppsala universitet; []
   Keywords : Medical sciences; diabetes mellitus; ischemia reperfusion; rat; end-stage renal disease; inflammation; fibrosis; hyaluronan; CD44; treatment; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

   Abstract : Diabetes mellitus (DM) is one of the leading causes of end stage renal failure. An increased susceptibility to renal ischemia/reperfusion (I/R)-injury was found in DM rats. Unilateral renal ischemia for as short as 20 minutes led to an irreversible progressive injury in DM kidneys, whereas the injury in non-DM kidneys was almost reversible. READ MORE

7. 5. Hepatic ischemia-reperfusion injury

   Author : Melroy Alistair D'Souza; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Hepatic ischemia-reperfusion (I/R) injury is a complex phenomenon occuring in response to interruption of the liver’s blood and oxygen supply and the subsequent restoration of blood flow and tissue oxygenation. Techniques to reduce blood loss and other intra-operative manoeuvers during liver resection can cause hepatic I/R injury. READ MORE
