- Background Internet-delivered self-help programmes with added guidance have shown efficacy in social anxiety disorder, unguided self-help has been insufficiently studied. Aims To evaluate the efficacy of guided and unguided self-help social anxiety disorder. Method Participants followed a cognitive-behavioural self-help programme in the form of either pure bibliotherapy or an internet-based treatment with therapist guidance and online group discussions. A subsequent trial was conducted to evaluate treatment specificity. Participants (n=235) were randomised to one of three conditions in the first trial, or one of four conditions in the second. Results Pure bibliotherapy and the internet-based treatment were better than waiting list on measures of social anxiety, general anxiety, depression and quality of life. The internet-based therapy had the highest effect sizes, but directly comparable effects were noted for bibliotherapy augmented with online group discussions. Gains were well maintained a year later. Conclusions Unguided self-help through bibliotherapy can produce enduring improvement for individuals with social anxiety disorder.

- Heparan sulfate (HS) proteoglycans influence embryonic development through interactions with growth factors and morphogens. The interactions depend on HS structure, which is largely determined during biosynthesis by Golgi enzymes. NDST ( glucosaminyl N-deacetylase/N-sulfotransferase), responsible for HSN-sulfation, is a key enzyme directing further modifications including O-sulfation. To elucidate the roles of the different NDST isoforms in HS biosynthesis, we took advantage of mice with targeted mutations in NDST1 and NDST2 and used liver as our model organ. Of the four NDST isoforms, only NDST1 and NDST2 transcripts were shown to be expressed in control liver. The absence of NDST1 or NDST2 in the knock-out mice did not affect transcript levels of other NDST isoforms or other HS modification enzymes. Although the sulfation level of HS synthesized in NDST1(-/-) mice was drastically lowered, liver HS from wild-type mice, from NDST1(-/-), NDST2(-/-), and NDST1(-/-), NDST2(-/-) mice all had the same structure despite greatly reduced NDST enzyme activity (30% of control levels in NDST1(-/-) NDST2(-/-) embryonic day 18.5 embryos). Enzymatically active NDST2 was shown to be present in similar amounts in wild-type, NDST1(-/-), and NDST1(-/-) embryonic day 18.5 liver. Despite the substantial contribution of NDST2 to total NDST enzyme activity in embryonic day 18.5 liver (approximate to 40%), its presence did not appear to affect HS structure as long as NDST1 was also present. In NDST1(-/-) embryonic day 18.5 liver, in contrast, NDST2 was responsible for N-sulfation of the low sulfated HS. A tentative model to explain these results is presented.

- BACKGROUND: This study investigated the efficacy of an Internet-based self-help program with minimal therapist contact via e-mail for Swedish university students with social phobia and public speaking fears. The main objective was to test if the Internet-based self-help program would be more effective if five live group exposure sessions were added. METHODS: Thirty-eight students meeting the diagnostic and statistical manual of mental disorders, 4th edition criteria for social phobia were randomized into two different treatment groups: Internet delivered cognitive behavior therapy combined with five group exposure sessions (ICBT+ exp) or the Internet program alone (ICBT). RESULTS: Results were analyzed on an intention-to-treat basis. Both treatment groups showed significant improvement from pre- to post-test, and from pre-test to 1-year follow-up, on all measured dimensions (social anxiety, general anxiety, depression levels, and quality of life). For both the groups, the average within-group effect sizes for the primary social anxiety scales, expressed as Cohen's d, were comparable to those seen in traditionally administered cognitive behavioral therapy both at post-test and at 1- year follow-up. CONCLUSIONS: The results suggest that the Internet-based self-help program on its own is efficient in the treatment of university students with social phobia. Adding group exposure sessions did not improve the outcome significantly.

- OBJECTIVES: To confirm and define the genetic association of STAT4 and systemic lupus erythematosus, investigate the possibility of correlations with differential splicing and/or expression levels, and genetic interaction with IRF5. METHODS: 30 tag SNPs were genotyped in an independent set of Spanish cases and controls. SNPs surviving correction for multiple tests were genotyped in 5 new sets of cases and controls for replication. STAT4 cDNA was analyzed by 5'-RACE PCR and sequencing. Expression levels were measured by quantitative PCR. RESULTS: In the fine-mapping, four SNPs were significant after correction for multiple testing, with rs3821236 and rs3024866 as the strongest signals, followed by the previously associated rs7574865, and by rs1467199. Association was replicated in all cohorts. After conditional regression analyses, two major independent signals represented by SNPs rs3821236 and rs7574865, remained significant across the sets. These SNPs belong to separate haplotype blocks. High levels of STAT4 expression correlated with SNPs rs3821236, rs3024866 (both in the same haplotype block) and rs7574865 but not with other SNPs. We also detected transcription of alternative tissue-specific exons 1, indicating presence of tissue-specific promoters of potential importance in the expression of STAT4. No interaction with associated SNPs of IRF5 was observed using regression analysis. CONCLUSIONS: These data confirm STAT4 as a susceptibility gene for SLE and suggest the presence of at least two functional variants affecting levels of STAT4. Our results also indicate that both genes STAT4 and IRF5 act additively to increase risk for SLE.

Steric influence on the excited-state lifetimes of ruthenium complexes with bipyridyl-alkanylene-pyridyl ligands.

Tidskriftsartikel (refereegranskat)abstract
- The structural effect on the metal-to-ligand charge transfer (MLCT) excited-state lifetime has been investigated in bis-tridentate Ru(II)-polypyridyl complexes based on the terpyridine-like ligands [6-(2,2'-bipyridyl)](2-pyridyl)methane (1) and 2-[6-(2,2'-bipyridyl)]-2-(2-pyridyl)propane (2). A homoleptic ([Ru(2)(2)](2+)) and a heteroleptic complex ([Ru(ttpy)(2)](2+)) based on the new ligand 2 have been prepared and their photophysical and structural properties studied experimentally and theoretically and compared to the results for the previously reported [Ru(1)(2)](2+). The excited-state lifetime of the homoleptic Ru-II complex with the isopropylene-bridged ligand 2 was found to be 50 times shorter than that of the corresponding homoleptic Ru-II complex of ligand 1, containing a methylene bridge. A comparison of the ground-state geometries of the two homoleptic complexes shows that steric interactions involving the isopropylene bridges make the coordination to the central Ru-II ion less octahedral in [Ru(2)(2)](2+) than in [Ru(1)(2))(2+). Calculations indicate that the structural differences in these complexes influence their ligand field splittings as well as the relative stabilities of the triplet metal-to-ligand charge transfer ((MLCT)-M-3) and metal-centered ((MC)-M-3) excited states. The large difference in measured excited-state lifetimes for the two homoleptic Ru-II complexes is attributed to a strong influence of steric interactions on the ligand field strength, which in turn affects the activation barriers for thermal conversion from (MLCT)-M-3 states to short-lived (MC)-M-3 states.

- This work presents a comparison of the crystal packing of three eukaryotic membrane proteins: human aquaporin 1, human aquaporin 5 and a spinach plasma membrane aquaporin. All were purified from expression constructs both with and without affinity tags. With the exception of tagged aquaporin 1, all constructs yielded crystals. Two significant effects of the affinity tags were observed: crystals containing a tag typically diffracted to lower resolution than those from constructs encoding the protein sequence alone and constructs without a tag frequently produced crystals that suffered from merohedral twinning. Twinning is a challenging crystallographic problem that can seriously hinder solution of the structure. Thus, for integral membrane proteins, the addition of an affinity tag may help to disrupt the approximate symmetry of the protein and thereby reduce or avoid merohedral twinning.

Profession och vetenskap : idéer och strategier för ett professionslärosäte
- 2009

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Förord av Björn Brorström, Prorektor Högskolan i Borås Ett professionslärosäte bedriver utbildning och forskning på vetenskaplig grund. Vetenskapliga metoder tillämpas och framkomna resultat prövas för att säkra tillförlitlighet och relevans. Förmågan att problematisera, formulera frågor och välja lämpliga metoder för att besvara frågor är egenskaper för god forskning och utmärkande för en stark utbildnings- och forskningsmiljö. Vid ett professionslärosäte finns samtidigt en stark strävan efter att i utbildning och forskning ta till vara den kunskap och de erfarenheter som professioner besitter och därigenom säkra en hög grad av praktisk relevans. Växelverkan mellan teori och praktik och erfarenhetsutbyte mellan forskare och praktiker är ständigt pågående. Det finns ingen avslutning på processen utan den pågår utan avbrott. En nödvändig förutsättning för ett fruktbart samarbete är en ömsesidig respekt och vilja att stödja och ifrågasätta varandra. Forskaren måste vara beredd på kritik för bristen på praktisk relevans och professionsföreträdaren måste vara beredd på att förtrogenhetskunskapens lämplighet ifrågasätts. Det är en fråga om med- och mothåll från båda håll i syfte att långsiktigt utveckla teori och praktik. Det är en utmaning att utveckla, etablera och därefter kontinuerligt försvara och förbättra professionslärosätet. Ett led i utvecklingen är att inom ramen för Högskolan i Borås föra en debatt om innebörden av ett professionslärosäte och vad vi behöver göra för att förbättra verksamheten. På uppdrag av rektor Lena Nordholm har medarbetare vid Bibliotekshögskolan utvecklat och ansvarat för en seminarieserie benämnd Profession och vetenskap. Seminarierna spände över ett brett fält. En av många viktiga frågor som diskuterades flitigt var huruvida vi ska forska om professioner, i för eller med, eller kanske alltihop samtidigt. Bidragen publiceras nu i denna antologi som ges ut inom ramen för Högskolan i Borås rapportserie Vetenskap för profession. Rapporten Profession och vetenskap – idéer och strategier för ett professionslärosäte, som redigerats av universitetsadjunkt Maria Lindh, kommer att få stor betydelse inom lärosätet och i vårt samarbete med företrädare för näringsliv, kulturliv och offentlig verksamhet. Jag ser det som en intressant fortsättning att anordna ett antal seminarier med inbjudna representanter för professioner där artiklarna i denna rapport kan ligga till grund för erfarenhetsutbyte och diskussioner.

Making sense of violence: voices of soldiers in the Congo (DRC)

Tidskriftsartikel (refereegranskat)abstract
- During the last years the DRC has made itself known in the world for terrible acts of violence committed by armed men – militia and the regular army – against the civilian population. The voices of the soldiers and combatants have so far been absent in the accounts of this violence. This silence is problematic, both because it makes it harder to understand such violence, but also because it reinforces stereotypes of African warriors as primitive and anarchic, driven by innate violence and tribal hatred. Enquiry into the particular discursive as well as material circumstances of the armed conflict in the DRC, which might better redress the complex and interrelated context in which ‘people in uniforms’ commit violence, is consequently impeded. The story we recount here emerges from soldiers within the main perpetrator of violence in the DRC today: the Integrated Armed Forces. The soldiers' interview texts challenge the dominant representation of soldiers and combatants in the DRC. The soldiers made sense of the prevalence of violence (in which they too had participated) in several interrelated ways, none of which reflected any expression of ‘natural’ (if dormant) violent tendencies, hatred or vengefulness for the enemy.

Why Do Soldiers Rape? Masculinity, Violence, and Sexuality in the Armed Forces in the Congo (DRC)

Tidskriftsartikel (refereegranskat)abstract
- This article explores the ways soldiers in the Congo speak about the massive amount of rape committed by the armed forces in the recent war in the DRC. It focuses on the reasons that the soldiers give to why rape occurs. It discusses how the soldiers distinguish between ‘‘lust rapes’’ and ‘‘evil rapes’’ and argues that their explanations of rape must be understood in relation to notions of different (impossible) masculinities. Ultimately, through reading the soldiers’ words, we can glimpse the logics—arguably informed by the increasingly globalized context of soldiering—through which rape becomes possible, and even ‘‘normalized’’ in particular warscapes.
