  • Chemical, mechanical and antibacterial properties of silver nanocluster/silica composite coated textiles for safety systems and aerospace applications

    • This work describes the chemical, mechanical and antibacterial properties of a novel silver nanocluster/silica composite coating, obtained by sputtering, on textiles for use in nuclear bacteriological and chemical (NBC) protection suites and for aerospace applications.The properties of the coated textiles were analyzed in terms of surface morphology, silver concentration and silver release in artificial sweat and synthetic tap water, respectively. No release of silver nanoparticles was observed at given conditions.The water repellency, permeability, flammability and mechanical resistance of the textiles before and after sputtering demonstrated that the textile properties were not negatively affected by the coating.The antibacterial effect was evaluated at different experimental conditions using a standard bacterial strain of Staphylococcus aureus and compared with the behavior of uncoated textiles.The coating process conferred all textiles a good antibacterial activity. Optimal deposition conditions were elaborated to obtain sufficient antibacterial action without altering the aesthetical appearance of the textiles.The antibacterial coating retained its antibacterial activity after one cycle in a washing machine only for the Nylon based textile.

  • Plasma glycosylphosphatidylinositol phospholipase D (GPI-PLD) and abdominal aortic aneurysm.
  • 2012
  • Ingår i: International Journal of Clinical and Experimental Medicine. - 1940-5901. ; 5:4, s. 306-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Recent reviews state that a circulating biomarker predicting aortic rupture risk would be a powerful tool to stratify patients with small screen-detected abdominal aortic aneurysm (AAA). In a current proteomic pilot-study elevated levels of the enzyme Glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) was shown in patients with small AAA compared with controls without aneurysm. In the present study we investigated the impact of plasma GPI-PLD as a biomarker in patients with AAA in relation to aneurysm size, and rupture. Plasma GPI-PLD was measured in patients with AAA (nonruptured, n=78 and ruptured, n=55) and controls without aneurysm (n=41) matched by age, sex and smoking habit. The plasma GPI-PLD levels were significantly lower in patients with ruptured compared nonruptured AAA which we interpreted as a result of hemodilution due to hemorrhage in patients with ruptured AAA. The plasma GPI-PLD levels were similar in patients with nonruptured AAA compared to the controls without aneurysm. Furthermore, there was no correlation between plasma GPI-PLD and aneurysm size in the group of patients with nonruptured AAA. In conclusion, the present study fails to show a connection between GPI-PLD and AAA. However, the definite role of GPI-PLD as a predictive marker needs to be further clarified in a follow-up cohort study.

  • Soluble urokinase plasminogen activator receptor in patients with abdominal aortic aneurysm
  • 2012
  • Ingår i: Thrombosis Research. - : Elsevier BV. - 0049-3848 .- 1879-2472. ; 130:3, s. 511-513

    • Introduction: In the present study we investigated the impact of soluble urokinase plasminogen activator receptor (suPAR) as a biomarker in patients with abdominal aortic aneurysm (AAA) in relation to conventional inflammatory markers, aneurysm size, and rupture. Methods: suPAR and conventional inflammatory markers were measured in 119 patients with AAA and 36 controls without aneurysm matched by age, gender and smoking habit. Results: The results support earlier studies suggesting a state of activated inflammatory response in patients with nonruptured AAA as expressed by elevated CRP and IL-6 compared with the controls. In contrast, suPAR showed similar levels in patients with nonruptured AAA compared with the controls. Unexpectedly, all follow-up patients (n = 16) have significant (p<0.001) elevated suPAR levels three years postoperatively compared preoperatively. Conclusions: suPAR does not seem to be a useful biomarker in the AAA disease. The role of the postoperative elevation of suPAR needs to be further elucidated. (C) 2012 Elsevier Ltd.

  • Non-peptide AT2-receptor agonists
  • 2011
  • Ingår i: Current opinion in pharmacology (Print). - : Elsevier BV. - 1471-4892 .- 1471-4973. ; 11:2, s. 187-192

    • The renin-angiotensin-system harbours two main receptor subtypes binding angiotensin II which are the AT1-receptor and the AT2-receptor. While the AT1-receptor has been a drug target in cardiovascular disease for many years, the AT2-receptor was only a subject of academic interest. This has changed with the design and synthesis of a first non-peptide, orally active AT2-receptor agonist, compound 21 (C21). First data using 021 revealed tissue protective effects and functional improvement after myocardial infarction and in hypertension-induced end organ damage, notably in a blood-pressure independent way. In all of these models, AT2-receptor mediated anti-inflammation seemed an important underlying mechanism. 021 is awaited to enter a phase I clinical study in 2011.

  • ABO blood groups and abdominal aortic aneurysm.
  • 2012
  • Ingår i: Transfusion and apheresis science. - : Elsevier BV. - 1473-0502 .- 1878-1683. ; 47:3, s. 351-3

    • Earlier studies have indicated an association between blood group non-O and atherosclerosis related vascular diseases. Abdominal aortic aneurysm (AAA) is traditionally regarded as a consequence of atherosclerosis. The aim of the present study was to investigate the association between ABO blood groups and AAA with special regard to a relation to AAA rupture. Prospectively, 504 patients operated on for AAA were investigated. Patients operated on for AAA have similar ABO blood group distributions as a population based control group. Furthermore, there was no significant difference in distribution of ABO blood group between patients operated on for ruptured AAA (n=174) and non-ruptured AAA (n=330). In conclusion, this study fails to demonstrate an association between ABO blood groups and AAA.

  • Discovery of a novel circulating biomarker in patients with abdominal aortic aneurysm: a pilot study using a proteomic approach.
  • 2012
  • Ingår i: Clinical and translational science. - : Wiley. - 1752-8062 .- 1752-8054. ; 5:1, s. 56-9

    • Abdominal aortic aneurysm (AAA) is a common condition with high mortality when ruptured. Most clinicians agree that small AAAs are best managed by ultrasonographic surveillance. However, it has been stated in recent reviews that a serum/plasma biomarker that predicts AAA rupture risk would be a powerful tool in stratifying patients with small AAA. Identification of such circulating biomarkers has been to date unsuccessful. In this study, we used a proteomic approach to find new, potential plasma AAA biomarker candidates. Prefractionated plasma samples were analyzed by two-dimensional differential in-gel electrophoresis to identify differentially expressed proteins between four patients with small AAA and four controls without aneurysm. Protein spots that differed significantly between patients and controls were selected and identified by mass spectrometry. Three protein spots had significantly different expression between patients and controls. The most interesting finding was that patients with small AAA had increased levels of the enzyme glycosylphosphatidylinositol-specific phospholipase D (GPI-PLD) compared with the controls without aneurysm. In conclusion, by using a proteomic approach, this pilot-study provides evidence of GPI-PLD as a novel potential plasma biomarker for AAA.

  • Early inflammatory response in patients with ruptured abdominal aortic aneurysm.

    • Multiorgan failure is the main cause of death in patients operated for ruptured abdominal aortic aneurysm (rAAA). The systemic inflammatory response plays a central role in the generation and maintenance of multiorgan dysfunction. The aim of the current study was to investigate the inflammatory response preoperatively in patients with ruptured and nonruptured AAA in relation to the clinical outcome. A total of 95 patients about to undergo repair of AAA (43 ruptured with shock, 12 ruptured without shock, and 40 elective) and 41 controls without aneurysm matched by age, gender, and smoking habits were investigated by inflammatory markers. There were significantly higher levels of interleukin 6 (IL-6; proinflammatory cytokine) and IL-10 (anti-inflammatory cytokine) in patients operated for ruptured compared to nonruptured AAA. In conclusion, the current data indicate that rupture of an AAA activates the inflammatory system with a compensatory anti-inflammatory response.
