  • New Technologies for DNA analysis-A review of the READNA Project.
  • 2016
  • In: New Biotechnology. - : Elsevier BV. - 1876-4347 .- 1871-6784.
  • Research review (peer-reviewed)abstract
    • The REvolutionary Approaches and Devices for Nucleic Acid analysis (READNA) project received funding from the European Commission for 4 1/2 years. The objectives of the project revolved around technological developments in nucleic acid analysis. The project partners have discovered, created and developed a huge body of insights into nucleic acid analysis, ranging from improvements and implementation of current technologies to the most promising sequencing technologies that constitute a 3(rd) and 4(th) generation of sequencing methods with nanopores and in situ sequencing, respectively.

  • On the potential for detecting scientific issues and controversies on Twitter : A method for investigation conversations mentioning research
  • 2019
  • In: Proceedings of ISSI.. ; , s. 2189-2198
  • Conference paper (peer-reviewed)abstract
    • In this study, we demonstrate how to collect Twitter conversations emanating from or referring to scientific papers. We propose segmenting the conversational threads into smaller segments and then compare them using information retrieval techniques, in order to find differences and similarities between discussions and within discussions. While the method still can be improved, the study shows that it is possible to collect larger conversations about research on Twitter, and that these are suitable for various automated methods. We do however identify a need to analyse these with qualitative methods as well.

  • High occurrence of mecC-MRSA in wild hedgehogs (Erinaceus europaeus) in Sweden
  • 2017
  • In: Veterinary Microbiology. - : Elsevier. - 0378-1135 .- 1873-2542. ; 207, s. 103-107
  • Journal article (peer-reviewed)abstract
    • We investigated the occurrence of mecC-MRSA in wild hedgehogs (Erinaceus europaeus) in Sweden and characterized the obtained isolates. Samples from 55 hedgehogs from five counties of Sweden were cultivated selectively for MRSA and putative isolates were confirmed by real-time PCR detecting mecA, mecC, nuc and PVL genes. mecC-MRSA was confirmed in 35 (64%) animals from three geographically separated counties. Confirmed isolates were spa-typed and tested for antimicrobial susceptibility by broth microdilution. Eight different spa-types were identified (t843, t978, t3391, t9111, t10751, t10893, t11015, t15312) of which t843 (49%) was the most common. The spa-types t843, t3391 and t978 were found in isolates from two counties. The study shows that mecC-MRSA is common in wild hedgehogs in two counties of Sweden but occurs in hedgehogs also in other parts of the country. Our findings suggest that hedgehogs could be a reservoir for mecC-MRSA. In addition, similar spa-types of isolates from hedgehogs and isolates previously described in domesticated animals and in humans indicates transfer between these populations.

  • Developing a rule-based method for identifying researchers on Twitter: The case of vaccine discussions
  • 2019
  • In: 17th International Conference on Scientometrics and Informetrics, ISSI 2019 - Proceedings Volume 2, 2019. - Rom. ; , s. 2618-2619
  • Conference paper (peer-reviewed)abstract
    • This study seeks to develop a method for identifying the occurrences and proportions of researchers, media and other professionals active in Twitter discussions. As a case example, an anonymised dataset from Twitter vaccine discussions is used. The study proposes a method of using keywords as strings within lists to identify classes from user biographies. This provides a way to apply multiple classification principles to a set of Twitter biographies using semantic rules through the Python programming language.

  • Phase evolution of radio frequency magnetron sputtered Cr-rich (Cr,Zr)(2)O-3 coatings studied by in situ synchrotron X-ray diffraction during annealing in air or vacuum
  • 2019
  • In: Journal of Materials Research. - : CAMBRIDGE UNIV PRESS. - 0884-2914 .- 2044-5326. ; 34:22, s. 3735-3746
  • Journal article (peer-reviewed)abstract
    • The phase evolution of reactive radio frequency (RF) magnetron sputtered Cr0.28Zr0.10O0.61 coatings has been studied by in situ synchrotron X-ray diffraction during annealing under air atmosphere and vacuum. The annealing in vacuum shows t-ZrO2 formation starting at similar to 750-800 degrees C, followed by decomposition of the alpha-Cr2O3 structure in conjunction with bcc-Cr formation, starting at similar to 950 degrees C. The resulting coating after annealing to 1140 degrees C is a mixture of t-ZrO2, m-ZrO2, and bcc-Cr. The air-annealed sample shows t-ZrO2 formation starting at similar to 750 degrees C. The resulting coating after annealing to 975 degrees C is a mixture of t-ZrO2 and alpha-Cr2O3 (with dissolved Zr). The microstructure coarsened slightly during annealing, but the mechanical properties are maintained, with no detectable bcc-Cr formation. A larger t-ZrO2 fraction compared with alpha-Cr2O3 is observed in the vacuum-annealed coating compared with the air-annealed coating at 975 degrees C. The results indicate that the studied pseudo-binary oxide is more stable in air atmosphere than in vacuum.

  • Early-Life Human Microbiota Associated With Childhood Allergy Promotes the T Helper 17 Axis in Mice
  • 2017
  • In: Frontiers in Immunology. - : Frontiers Media SA. - 1664-3224. ; 8
  • Journal article (peer-reviewed)abstract
    • The intestinal microbiota influences immune maturation during childhood, and is implicated in early-life allergy development. However, to directly study intestinal microbes and gut immune responses in infants is difficult. To investigate how different types of early-life gut microbiota affect immune development, we collected fecal samples from children with different allergic heredity (AH) and inoculated germ-free mice. Immune responses and microbiota composition were evaluated in the offspring of these mice. Microbial composition in the small intestine, the cecum and the colon were determined by 16S rRNA sequencing. The intestinal microbiota differed markedly between the groups of mice, but only exposure to microbiota associated with AH and known future allergy in children resulted in a T helper 17 (Th17)-signature, both systemically and in the gut mucosa in the mouse offspring. These Th17 responses could be signs of a particular microbiota and a shift in immune development, ultimately resulting in an increased risk of allergy.
