    • AIM: Endovascular skills are an integral part of modern-day vascular surgery. The STRESS machine has been developed to test these skills in vascular surgeons. This study aims to define an optimal pass/fail cutoff value for the STRESS test score. METHODS: The STRESS machine consists of a dry glass model of the abdominal aorta and its tributaries with various stenotic lesions, elongations, and tortuosities. A camera and computer software are used to simulate plain fluoroscopy-mode. The test subjects are given two assignments after which two reviewers use a combination of the ICEPS and MRS to produce the final total score; 43 subjects were tested. According to previous endovascular experience, subjects were classified into four groups: novice-low (no experience, less than 11 performed procedures, less than 50 assisted procedures), novice-high (11-25 performed procedures, more than 50 assisted procedures), intermediate (1-10 performed and >11-25 assisted procedures, 11-25 performed and >1-10 assisted procedures or 25-50 performed procedures) and advanced (more than 50 performed procedures). RESULTS: Test-score and noted experience showed a correlation of 0.794. All intermediate and advanced test subjects scored more than 50 points compared to 4 out of 15 novices. CONCLUSION: We demonstrated that it is possible to determine an optimal cut-off value for competence testing with the STRESS machine.

  • Encapsulated vs. free yeast : A comparative proteomic study
  • 2011
  • Ingår i: International PhD course in Industrial Biotechnology for lignocellulose based processes, October 16-21, Göteborg, Sweden.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • In the search for a replacement for fossil fuels, due to their depletion as well as an increased concern about our environment, 2nd generation bioethanol comes out as one of the most promising alternatives. There are challenges in several steps of lignocellulose processing – especially due to the formation of for yeast inhibitory compounds during pretreatment and hydrolysis. It has previously been shown that encapsulation of the yeast in membranes made of an alginate gel enables the yeast to survive otherwise toxic hydrolysates. The physiological changes arising from encapsulation are however largely unknown, although it has been shown that the macromolecular composition of the yeast changes during prolonged cultivation. In this study we have therefore performed a comparative proteomic study of yeast grown in capsules and in suspension in anaerobic batch cultivations.
