Studies on hereditary C2 deficiency: Frequent occurrence of severe infections, atherosclerosis and rheumatological manifestations

Popular Abstract in Swedish Komplementsystemet utgör en del av den medfödda immuniteten och är viktigt i försvaret mot angripande mikroorganismer. Ärftlig C2-brist (C2D) är en av de vanligaste bristerna inom komplementsystemet och förekommer i en frekvens av 1: 20 000 hos personer med västerländsk härstamning. I de aktuella undersökningarna har mer än 40 personer med C2D identifierats och observerThe complement system is a part of the innate immunity and is essential in the defence against microorganisms. Hereditary C2 deficiency (C2D) is one of the most common complement deficiency states with an estimated prevalence of 1:20,000 in persons of Western descent. In the present investigation, the identification of more than 40 C2D persons at a single centre combined with long observation peri

Strategies for the transition to breeding in time-selected migration

In time-selected migration birds adapt their fuel deposition and flight behaviour to maximise sustained migration speed. What are the expectations for the final part of spring migration when the transition to breeding takes place and the criterion of a maximum total migration speed is no longer relevant? Two possible strategies representing different ends of the capital – income spectrum are evalu

Neurogenesis and transplantation in stroke-damaged brain

Popular Abstract in Swedish Stroke hos unga vuxna råttor och möss utlöser neurogenes i den skadade regionen striatum samt i den intakta hippocampus, men eftersom stroke framförallt drabbar äldre individer, är det av största vikt att utröna åldrandets effekt på hjärnans mekanismer för återhämtning. Gamla och unga vuxna råttor inducerades med stroke genom transient ocklusion av mellersta hjärnartäreStroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. Aged and young adult rats were subjected to stroke by transient occlusion of the middle cerebral artery and proliferating cells were labeled by intraperitoneal administ

Characterization of the DNA binding features of Saccharomyces castellii Cdc13p

The principal function of Saccharomyces cerevisiae Cdc13p is to provide a loading platform to recruit complexes that provide end protection and telomere replication. We isolated the Saccharomyces castellii Cdc13p homolog (scasCdc13p) and characterized the in vitro DNA binding features of the purified recombinant scasCdc13p. The full-length scasCdc13p binds specifically to G-rich single-stranded te

Created by God : How Somalis in Swedish Exile Reassess the Practice of Female Circumcision

Popular Abstract in Swedish Avhandlingen handlar om hur kvinnlig omskärelse diskuteras av svensksomalier, men också om hur kvinnlig omskärelse diskuteras offentligt i det svenska samhället. Det konstateras att det finns en stor klyfta mellan dessa diskurser. Utifrån en analys av den interna debatten om kvinnlig omskärelse bland somalier i Malmö, hävdas att denna praktik debatteras och omvärderas 'Created by God' presents the views of Swedish Somalis on female circumcision and contrasts it to the Swedish public discourse on the issue. Despite the lack of documented illegal cases of female circumcision in Sweden, it is constantly claimed in the public discourse that female circumcision (female genital mutilation) is a practice upheld by the Somali exile group in Sweden. Based on an analys

Med främmande bagage : Tankar och erfarenheter hos unga människor med ursprung i en annan kultur eller Det postmoderna främlingskapet

Popular Abstract in Swedish Allt fler ungdomar i vårt land, liksom i många andra länder, lever i vardagen med mer än en kultur. En femtedel av eleverna i den svenska skolan är antingen själva födda i ett annat land eller har minst en förälder med utländsk bakgrund. För många av dessa barn och ungdomar har därför inte samhällets dominerande kultur funnits med från början av deras liv. Bekantskapen The present study is based on interviews with 22 youth and young adults. The perspective is phenomenological, since my aim has been to analyse and describe the everyday world as it presents itself to these young people. A process begins in the encounter with the majority culture and the emphasis is on how they think about events and experiences along the road to a more complex life-world. The proc

Selective immuno-supported liquid membrane (ISLM) extraction, enrichment and analysis of 2,4,6-trichlorophenol

2,4,6-Trichlorophenol (2,4,6-TCP) was extracted from liquid samples (standards and spiked river water) using immuno-supported liquid membrane (ISLM) extraction followed by fluorescence flow immunoassay (FFIA) detection of the immuno-extracted analyte. ISLM-FFIA involves simultaneous on-line sample clean-up, enrichment and detection of analytes. The analyte is transported from a continuously flowin

Diffractive photoproduction of rho mesons with large momentum transfer at HERA

The diffractive photoproduction of rho mesons, ep -> e rho Y, with large momentum transfer squared at the proton vertex, vertical bar t vertical bar, is studied with the H1 detector at HERA using an integrated luminosity of 20.1 pb(-1). The photon-proton centre of mass energy spans the range 75 < W < 95 GeV, the photon virtuality is restricted to Q(2) < 0.01 GeV2 and the mass My of the proton remn

Enhanced and prolonged efficacy of superantigen-induced cytotoxic T lymphocyte activity by interleukin-2 in vivo

The bacterial superantigen, staphylococcal enterotoxin A (SEA) activates T cells with high frequency and directs them to lyse MHC-class-II-expressing cells in superantigen-dependent cell-mediated cytotoxicity (SDCC). Treatment of mice with SEA induced strong CD8+ T-cell(CTL)-mediated SDCC, as well as abundant cytokine production from CD4+ and CD8+ T cells. However, both cytotoxicity and cytokine r

Long-term effects of childbearing on mortality: Evidence from pre-industrial Sweden

This paper presents an analysis of the impact of childbearing history on later-life mortality for ever-married men and women using historical micro-level data of high quality for southern Sweden. The analysis uses a Cox proportional hazards model, estimating the effects on old-age mortality of number of births and timing of first and last births. By studying the effects of previous childbearing on

Image solution for clamped finite beams

An image solution for the forced response of a clamped finite beam is developed. The finite beam is replaced by an infinite beam under spatially periodic excitation and periodic support reactions. The response is then found by a Fourier transform approach, making use of the periodicity. An explicit expression is found, using the Poisson sum formula. The aim is to describe the potential of using th
