The respiratory pathogen Moraxella catarrhalis is a human-specific commensal that frequently causes acute otitis media in children and stimulates acute exacerbations in chronic obstructive pulmonary disease patients. The exact molecular mechanisms defining host-pathogen interactions promoting pathogenesis are not clearly understood. Limited knowledge hampers vaccine and immunotherapeutic developme
Islet autoantibodies (IAs) precede the clinical onset of type 1 diabetes (T1D); however, the knowledge is limited about whether the prodrome affects complete blood counts (CBCs) in 4- to 12-year-old children with increased genetic risk for T1D. This study tested whether CBCs were altered in 4- to 12-year-old children without (n = 376) or with one or several IAs against insulin, GAD65, or IA-2 (n =
Objective: To study the impact of common noncomposite disease activity measures on sick leave in biologics-treated patients with rheumatoid arthritis (RA). Methods: Data from study visits by biologics-treated RA patients of working age (<65 years) in the observational South Swedish Arthritis Treatment Group Register between 2005 and 2011, were included (5,118 visits by 941 patients). We performed
There are more child refugees in Europe than at any point since the end of the Second World War (Save the Children 2016). This is affecting both communities on the move and communities where uprooted people are resettling. A humanitarian problem on this scale demands a socially just response. For young refugees, education is a fundamental means of integrating into their new context and the act
In spatially heterogeneous environments, coexistence between competing species can be facilitated by spatially mediated tradeoffs. In this paper we develop a mechanistic model to investigate under which circumstances interspecific differences in the tradeoff between foraging efficiency and travel costs can allow two central place foraging species to coexist in spite of considerable overlap in reso
The Swedish Cambrian ‘Orsten’-type fossil sites have yielded diverse secondarily phosphatized three-dimensionally preserved microfossils, mainly of arthropod affinities. Similar material has also been recorded from Canada, the UK, Poland, Siberia, China and Australia. Only one other non-arthropod group, the Cycloneuralia, is commonly reported from any of these sites, leading to the general assumpt

Research on stem-cell transplantation has indicated that the success of transplantation largely depends on synchronizing donor cells into the G0/G1 phase. In this study, we investigated the profile of embryonic stem (ES) cell synchronization and its effect on the formation of embryonic bodies (EBs) using cell culture with serum deprivation. The D3 cell line of ES cells was used, and parameters suc
Natural selection often produces parallel phenotypic changes in response to a similar adaptive challenge. However, the extent to which parallel gene expression differences and genomic divergence underlie parallel phenotypic traits and whether they are decoupled or not remains largely unexplored. We performed a population genomic study of parallel ecological adaptation among replicate ecotype pairs
This study documents the early post-embryonic developmental stages (protaspides and early meraspides) of the Cambrian trilobite Ellipsostrenua granulosa (Ahlberg, 1984) from the Gärdsjön Formation of Jämtland, Sweden. The early protaspid stage is characterized by a circular outline of the exoskeleton, two pairs of fixigenal spines, a short preglabellar field, a genal swelling, and prominent bacull
A rapid shift from traditional Sanger sequencing-based molecular methods to the phylogenomic approach with large numbers of loci is underway. Among phylogenomic methods, restriction site associated DNA (RAD) sequencing approaches have gained much attention as they enable rapid generation of up to thousands of loci randomly scattered across the genome and are suitable for nonmodel species. RAD data
This study was directed at assessing the effects of embryonic bodies on differentiation of the embryonic stem cells. The embryonic bodies of different days gained by means of hanging, suspending and hung-suspended were processed by all-trans retinotic acids for 4 days. Then they were detected by immunocytochemistry methods and were measured to detect the fluorescence intensity changes of calcium a
Doktorsavhandling framlagd vid Institutionen för Tema, Linköpings universitet 1994. Avhandlingen behandlar produktion och och bruk av porträtt i Sverige under perioden 1840-65, då fotografiska porträtt gradvis introducerades på den svenska marknaden och trängde tillbaka vissa delar av en etablerad porträttmarknad. Detta dynamiska skede granskas med avseende på samspelet mellan beställare och portr
Previous studies have reported that chromosome synteny in Lepidoptera has been well conserved, yet the number of haploid chromosomes varies widely from 5 to 223. Here we report the genome (393 Mb) of the Glanville fritillary butterfly (Melitaea cinxia; Nymphalidae), a widely recognized model species in metapopulation biology and eco-evolutionary research, which has the putative ancestral karyotype
Prostate cancer (PCa) is the most common cause of cancer-related death in men after lung cancer. Annually, more than 9000 new cases are diagnosed in Sweden and 2500 of them die each year. Metastatic prostate cancer can be treated with castration. However, the disease eventually recurs within 2 years in more aggressive form and becomes insensitive to castration which is termed as castration resista
We characterize allelic and gene expression variation between populations of the Glanville fritillary butterfly (Melitaea cinxia) from two fragmented and two continuous landscapes in northern Europe. The populations exhibit significant differences in their life history traits, e.g. butterflies from fragmented landscapes have higher flight metabolic rate and dispersal rate in the field, and higher
Background: The endosymbiont Wolbachia pipientis causes diverse and sometimes dramatic phenotypes in its invertebrate hosts. Four Wolbachia strains sequenced to date indicate that the constitution of the genome is dynamic, but these strains are quite divergent and do not allow resolution of genome diversification over shorter time periods. We have sequenced the genome of the strain wBol1-b, found
