Editorial collection (peer-reviewed)abstract
- The conference Codex and Code: Aesthetics, Language and Politics in an Age of Digital Media (NorLit 2009)was held at the Royal Institute of Technology (KTH) in Stockholm, August 6–9, 2009. The conference was organized by the Nordic Association for Comparative Literature (NorLit); the Department of Culture and Communication, Linköping University; the School of Computer Science and Communication, Royal Institute of Technology (KTH); the Department of Comparative Literature, Stockholm University; the Department of Culture and Communication, Södertörn University College; and the Department of Comparative Literature, Uppsala University. The aim of the conference was to develop the study of Comparative Literature through Nordic collaboration both in its own discipline and in Modern Language and Cultural studies. As the title for the conference suggests, the principal question for the conference was the challenge that the study of literature encounters in an age of digitalization and globalization. It was our aim to encourage discussion of how literary studies respond to the ongoing changes in media and technology, politics and economy. Many have argued that the Humanities currently are in a state of crisis. We believe that the discipline seldom has found itself in such an interesting and fruitful historical moment. Several of these questions have surfaced during earlier media system changes, in particular during Romanticism and Modernism, which provided the conference with an historical frame. The conference Codex and Code also addressed questions of authenticity and originality, identity and gender, literary genres and reading practices, media and materiality, culture and popular culture, language and history, world literature, work aesthetics, translations, and canon formation. The conference Codex and Code wanted to stimulate interdisciplinary scholarly research of the literary in a broad sense. The conference was open to scholars in Comparative Literature and in Classical and Modern Languages, Aesthetics, Media and Communication studies, Film and Theatre studies, Philosophy and adjacent disciplines. The conference was organized around a number of thematic sessions in which researchers and scholars presented and discussed papers. The conference has received generous financial support from the Bank of Sweden Tercentenary Foundation, Magnus Bergwall foundation, Granholms foundation, Linköping University, School of Computer Science and Communication, Royal Institute of Technology, Svenska litteratursällskapet; the Swedish Academy, Swedish Science Council, and Vitterhetsakademien.

In Vitro Assessment of Flow Patterns and Turbulence Intensity in Prosthetic Heart Valves Using Generalized Phase-Contrast MRI
- 2010
-
In: JOURNAL OF MAGNETIC RESONANCE IMAGING. - : John Wiley and Sons, Ltd. - 1053-1807 .- 1522-2586. ; 31:5, s. 1075-1080

Journal article (peer-reviewed)abstract
- Purpose: To assess in vitro the three-dimensional mean velocity field and the extent and degree of turbulence intensity (TI) in different prosthetic heart valves using a generalization of phase-contrast MRI (PC-MRI). Materials and Methods: Four 27-mm aortic valves (Bjork-Shiley Monostrut tilting-disc, St. Jude Medical Standard bileaflet, Medtronic Mosaic stented and Freestyle stentless porcine valve) were tested under steady inflow conditions in a Plexiglas phantom. Three-dimensional PC-MRI data were acquired to measure the mean velocity field and the turbulent kinetic energy (TKE), a direction-independent measure of TI. Results: Velocity and TI estimates could be obtained up and downstream of the valves, except where metallic structure in the valves caused signal void. Distinct differences in the location, extent, and peak values of velocity and TI were observed between the valves tested. The maximum values of TKE varied between the different valves: tilting disc, 100 J/m(3); bileaflet, 115 J/m(3); stented, 200 J/m(3); stentless, 145 J/m(3). Conclusion: The TI downstream from a prosthetic heart valve is dependent on the specific valve design. Generalized PC-MRI can be used to quantify velocity and TI downstream from prosthetic heart valves, which may allow assessment of these aspects of prosthetic valvular function in postoperative patients.

Risk factors for hemorrhage during local intra-arterial thrombolysis for lower limb ischaemia
- 2011

Journal article (peer-reviewed)abstract
- Assessment of clinical risk factors for haemorrhagic complications in patients undergoing intra-arterial thrombolysis for lower limb ischaemia. Retrospective reviews of consecutive patients subjected to intra-arterial thrombolysis due to lower limb ischemia at the Vascular Center, Malmö University Hospital, during a 5-year period from 2001 to 2005. Two hundred and twenty intra-arterial thrombolytic procedures were carried out in 195 patients (46% women), median age 73 years. Haemorrhagic complications were recorded in 72 procedures (33%), of which 13 were discontinued. Haemorrhage at the introducer and distant sites occurred in 53 and 32 procedures, respectively. Thrombolysis for occluded synthetic grafts was associated with higher risk of haemorrhage (P = 0.043). The platelet count was lower (P = 0.017) and the dose of alteplas higher (P = 0.041) in bleeders than in non-bleeders. Age was not associated with haemorrhage (P = 0.30). Two patients died during thrombolysis, one of them due to intracerebral haemorrhage. The grade of thrombolysis was an independent predictor of both in-hospital amputation (P < 0.001; OR 3.5 [95% CI 2.1-5.8]) and mortality (P = 0.021; OR 3.0 [95% CI 1.2-7.9]). The in-hospital amputation-free survival rate was 85% (188/220). Haemorrhage associated with thrombolysis is common, but does seldom require discontinuation of treatment. Insertion of introducers for local thrombolysis through synthetic grafts, lower platelet count and higher alteplas dose were found to be risk factors for haemorrhage. An algorithm for clinical management of haemorrhage has been proposed.

Kinetic analysis of a naturally occurring bioremediation enzyme : dehaloperoxidase-hemoglobin from Amphitrite ornata
- 2010
-
In: Journal of Physical Chemistry B. - : American Chemical Society (ACS). - 1520-6106 .- 1520-5207. ; 114:43, s. 13823-13829
-
Journal article (peer-reviewed)abstract
- The temperature dependence of the rate constant for substrate oxidation by the dehaloperoxidase-hemoglobin (DHP) of Amphitrite ornata has been measured from 278 to 308 K. The rate constant is observed to increase over this range by approximately a factor of 2 for each 10 °C temperature increment. An analysis of the initial rates using a phenomenological approach that expresses the peroxidase ping-pong mechanism in the form of the Michaelis-Menten equation leads to an interpretation of the effects in terms of the fundamental rate constants. The analysis of kinetic data considers a combination of diffusion rate constants for substrate and H(2)O(2), elementary steps involving activation and heterolysis of the O-O bond of H(2)O(2), and two electron transfers from the substrate to the iron. To complete the analysis from the perspective of turnover of substrate into product, density function theory (DFT) calculations were used to address the fate of phenoxy radical intermediates. The analysis suggests a dominant role for diffusion in the kinetics of DHP.
