The management of duodenal atresia (DA) in two Scandinavian pediatric centers is reported. A total of 67 infants with DA were retrospectively analyzed. A high incidence of associated anomalies was present, including Down's syndrome in 40% and cardiac anomalies in 20% of the infants. No immediate postoperative mortality was noted. The operative procedures were duodenoduodenostomy and duodenojejunos

The clinical usefulness of the preoperative determination of C-Reactive protein (CRP) in patients with suspected acute appendicitis was studied in 156 consecutive patients undergoing acute appendicectomy. The CRP values were found to increase with an advancing stage of the appendiceal inflammation found at operation and the length of the preoperative phase of illness. Eight out of 66 patients with

The present author has investigated the frequency with which normal appendices are found at appendectomy in different phases of the menstrual cycle. The study is based on 504 female patients, 15–45 years of age, who were perated on for suspected acute appendicitis during the period from 1976 to 1982. The results are shown in Tables 1 and 2. The frequency of acute appendicitis in the luteal phase o

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
