Forskningsöversikt (refereegranskat)abstract
- The qualitative literature review includes 34 articles published in English-language, peer-reviewed journals to obtain a Nordic perspective on the status of the research on how the idea of inclusion implemented into practice is reflected in the literature from 2009 through 2019. Qualitative content analysis was conducted. In the analysis, we identified the characteristics of the studies, how inclusion and inclusive education were defined, and which themes concerning the idea of inclusion into practice that emerged from the review. Articles from five Nordic countries were found, Sweden with most of the publications. Almost twice as many of the sampled articles used qualitative methods as quantitative. Inclusion and inclusive education were seldom defined explicit, and the different way of understanding inclusion that emerges was human rights and democratic principles, placement of SEN-students, participation and belongingness, and high-quality learning for all students. Three themes was highlighted in the transformation of the idea into practice: Placement and the organisation of schooling, Teachers' beliefs and attitudes, and Students' and parents' experiences. This literature review shows that few research studies have focused specific on how to transform the idea of inclusion into practice.

- Biological characteristics of virus quantitatively rescued from different cell types present in lymph nodes of HIV-1-infected individuals in various stages of their disease were determined, not including patients with AIDS defining illness. Viruses were obtained by cocultivation with donor monocyte-derived macrophages and T-lymphocytes and their biological phenotype compared to viruses obtained from the peripheral blood mononuclear cells of the same patient. The biological phenotype was determined on established cell lines (U937-2, CEM, and MT-2) and on the U87.CD4 coreceptor indicator cell lines and variable region 3 (V3) of the envelope was subjected to direct sequencing. All isolates obtained from lymph node subsets used CCR5 as coreceptor. Furthermore, these viruses were also sensitive to inhibition by beta-chemokines as analyzed for viruses of one patient. All 12 V3 regions showed a unique sequence indicating compartmentalization within each patient. The biological phenotype of CCR5-dependent (R5) HIV-1 isolates obtained from PBMC resembles the phenotype of viruses isolated from different lymph node cell subsets.

- Porous gold nanoparticles were obtained from nanoparticle alloys of gold and silver. The alloy nanoparticles were prepared by reducing the gold and silver precursors, HAuCl4 and AgNO3, respectively with NaBH4. The reduction was made in a microemulsion of water-in-oil type and the precursors were contained in the water droplets. The droplet size of the microemulsion was 25-30 nm and the size of the mixed nanoparticles was 5-7 nm. The position of the plasmon band in the absorption spectrum, as well as analysis by energy-dispersive X-ray spectroscopy linked to high resolution scanning transmission electron microscopy showed that the nanoparticles were true alloys, not of core-shell type. The mixed nanoparticles were subsequently dealloyed by treatment with nitric acid, which dissolved silver much more readily than gold.

- Gastrointestinal (GI) mucus is continuously secreted and lines the entire length of the GI tract. Essential for health, it keeps the noxious luminal content away from the epithelium. Our aim was to characterize the composition and structure of mucus throughout the various GI segments in dog.Mucus was collected from the stomach, small intestine (duodenum, jejunum, ileum), and large intestine (cecum, proximal and distal colon) from dogs. Composition was determined by multi-omics. Structural properties were investigated using cryoSEM and rheology.GI mucus contained 74-95% water and maintained a pH around 6.5. The proteome was similar across the different GI segments. The highest abundant secreted gel-forming mucin in the gastric mucus was mucin 5AC, whether mucin 2 had highest abundance in the intestinal mucus. Lipid and metabolite abundance was generally higher in the jejunal mucus than the colonic mucus. CryoSEM microscopy revealed smaller pore size in small intestinal mucus, which increased in the large intestine. All mucus samples showed shear-thinning behavior and characteristics of gel-like structure.In conclusion, the mucus is a highly viscous and hydrated material. These data provide an important baseline for future studies on human and canine intestinal diseases and the dog model in drug absorption.

Bartonella Infections in Sweden: : Clinical Investigations and Molecular Epidemiology
- 2007
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Characteristically, in infections that are caused by the zoonotic pathogen Bartonella naturally infected reservoir hosts are asymptomatic, where infected incidental, non-natural, hosts develop symptomatic disease. Cat-scratch disease (CSD) is a well known example. Bartonella infections in humans may be self-limiting or fulminant and affect different organ systems. The objectives of the present thesis were to (1) identify and characterise Bartonella infection cases in Sweden, (2) to investigate certain human populations regarding Bartonella infections, and (3) compare natural populations of different Bartonella species. Cases with typical and atypical CSD were recognised by using a combination of PCR and serology. Gene sequence comparisons of different genes in B. henselae isolates from the United States and Europe showed that ftsZ gene variation is a useful tool for Bartonella genotyping. Myocarditis was a common finding among Swedish elite orienteers succumbing to sudden unexpected cardiac death (SUCD). The natural cycle of Bartonella spp., the life style of orienteers, elevated antibody titres to Bartonella antigens, Bartonella DNA amplified from myocardium and the lack of another feasible explanation make Bartonella a plausible aetiological factor. The first reported case of Bartonella endocarditis (B. quintana) was identified in an immunocompromised patient who underwent heart valve replacement. The patient had been body louse-infested during his childhood. It is hypothesised that a chronic B. quintana infection was activated by the immunosuppression. There was no evidence of an ongoing trench fever (TF) epidemic in a Swedish homeless population, although an increased risk for exposure to Bartonella antigens was demonstrated. The lack of louse infestation might explain the absence of B. quintana bacteremia and low B. quintana antibody titres. Comparisons of genetic loci and the whole genomes of environmental B. grahamii isolates from the Uppsala region, Sweden displayed variants that were not related to specific host species but to geographic locality. Natural boundaries seemed to restrict gene flow.

- Blood samples and epidemiological data were collected from 50 homeless patients in central Stockholm, Sweden. Sera were analysed for antibodies to B. henselae, B. quintana, B. elizabethae and B. grahamii. Whole blood was cultured and used as substrate for a newly developed quantitative real time polymerase chain reaction (QPCR) specifically targeting Bartonella spp. DNA. 61 matched blood donor sera were used as controls. Homeless patients were significantly more often seropositive to Bartonella spp. than controls (OR 7.58 (3.30-17.39), p<0.05). Reactivity to the B. elizabethae antigen was dominating, although the difference between patients and controls was most significant in seroreactivity to the B. henselae antigen. There was no evidence of an ongoing B. quintana epidemic. The absence of louse infestation could explain the lack of B. quintana bacteraemia and the failure to amplify Bartonella DNA.
