  2. 21. Functional and metabolic alterations in skeletal muscle in response to physiological and pathophysiological stressors

    Author : Theresa Mader; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Skeletal muscle performance is essential for our body’s movement as well as for the wholebody metabolism. In health and disease, skeletal muscle is exposed to various endogenous and exogenous stressors, influencing its physiological functions. READ MORE

  4. 22. Microdialysis in Liver Ischemia and Reperfusion injury

    Author : Anders Winbladh; Per Sandström; Per Gullstrand; Arthur Revhaug; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Introduction: New chemotherapy regimens and improvements in surgical technique have increased the number of patients with liver tumours eligible for curative liver resection. There is a significant risk of bleeding during liver surgery, but this risk can be reduced if the portal inflow is temporarily closed; i.e. the Pringles maneuver (PM). READ MORE

  5. 23. PTPs : redox controlled regulators of cell signaling and transformation

    Author : Åsa Sandin; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Protein tyrosine phosphatases (PTPs) are important redox regulated enzymes that control the tyrosine phosphorylation status in the cell. These studies aimed to increase the understanding on how PTPs are controlled by reversible oxidation in different pathological settings such as hypoxia and restenosis and to which extent oxidized PTPs contribute to certain diseases.

  6. 24. Adsorption, desorption, and redox reactions at iron oxide nanoparticle surfaces

    Author : Lelde Krumina; MEMEG; []
    Keywords : Ferrihydrite; Goethite; Secondary metabolites; Reductive dissolution; Catalytic oxidation; hydroxyl radicals; Fenton reaction; SOM decomposition;

    Abstract : Iron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport.

  7. 25. Novel methods for the identification of cellular S-glutathionylated proteins and sites of glutathionedependent modification using affinity chromatography and proteomic analyses

    Author : Ylva Hamnell-Pamment; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Reactive oxygen species (ROS) are formed during normal respiration in the mitochondria through electron leakage to oxygen. During normal metabolism, several enzymes and low-molecular weight antioxidants work towards eliminating ROS in a well-coordinated manner. READ MORE
