Popular Abstract in Swedish Streptococcus pyogenes (grupp A streptokocker) är en bakterie som orsakar flera olika infektionssjukdomar hos människan, av vilka de vanligaste är halsfluss och svinkoppor. För att kunna infektera sin värd använder sig en patogen bakterie av virulens-faktorer och S. pyogenes uttrycker flera olika sådana. Den viktigaste av dessa anses vara M proteinet som Streptococcus pyogenes (group A Streptococcus) expresses several different virulence factors. Of these, the M protein is regarded as one of the most important, because it confers resistance to phagocytosis, allowing the bacterium to multiply in blood. A remarkable property of M proteins is their ability to bind different human plasma proteins, in partic

Popular Abstract in Swedish Talet om det mångkulturella i skolan och samhället: En analys av diskurser om det mångkulturella inom utbildning och politik åren 1973-2006 Det svenska samhället har under de senaste tre decennierna påverkats av debatter, rapporteringar och diskussioner om det mångkulturella samhället. Frågan om hur man ska handskas med ?det mångkulturella? har uppfattats och beskrivitThe debate on "multicultural issues" has had a considerable impact on society, and in Sweden, dealing with such issues has been described and defined as a major problem. The aim of the present thesis is to analyse the various contents of discourses on multicultural issues that have influenced education and policy documents during the period 1973-2006. On several occasions, the Swedish government h

Emission sources in proton-nucleus and nucleus-nucleus collisions at intermediate energies have been studied. Pion excitation functions from the absolute threshold to 500 MeV have been measured with an ion beam of continuously varying energy with an energy resolution of 1 MeV. Total yields, angular distributions and target mass dependences are compared to QMD and BUU calculations. Proton/deutero

Recently, unusual forms of leukemias have developed as complications following retroviral transfer of potentially therapeutic genes into hematopoietic cells. A crucial component in the pathogenesis of these complications was the upregulation of a cellular proto-oncogene by random insertion of the retroviral gene transfer vector. These findings have great implications for the genetic manipulation o

We present two methods for finding a lowest common ancestor (LCA) for each pair of vertices of a directed acyclic graph (dag) on n vertices and m edges. The first method is surprisingly natural and solves the all-pairs LCA problem for the input dag on n vertices and m edges in time O(nm). As a corollary, we obtain an O(n(2))-time algorithm for finding genealogical distances considerably improving

Although the benefits of topical sensitizer administration have been confirmed for photodynamic therapy (PDT) ALA-induced, protoporphyrin IX is the only sensitizer clinically used with this administration route. Unfortunately, ALA-PDT results in poor treatment response for thicker lesions. Here, selectivity and depth distribution of the highly potent sensitizer meso-tetra(hydroxyphenyl)chlorin (mT

The lower excited states of 2-benzoylthiophene have been studied using ab initio quantum chemical methods based on multiconfigurational wave functions. Six singlet and six triplet excited states have been characterized. The geometry has been optimized for the two lowest triplet states, which are responsible for the photoreactivity of the chromophore in the photosensitizing drug tiaprofenic acid. T

The aim of this study was to explore the previous personalities of patients, their behavior during the course of the disease, and the relationship between the previous personality and vocally disruptive behavior of severely demented patients. Twenty-one severely demented patients identified as vocally disruptive and 19 severely demented control subjects who were matched for gender and ward were st

Biological molecular motors that are constrained so that function is effectively limited to predefined nanosized tracks may be used as molecular shuttles in nanotechnological applications. For these applications and in high-throughput functional assays (e. g., drug screening), it is important that the motors propel their cytoskeletal filaments unidirectionally along the tracks with a minimal numbe

Recent Hubble Space Telescope observations of a large sample of globular clusters reveal that every cluster contains between 40 and 400 blue stragglers.The population does not correlate with either stellar collision rate (as would be expected if all blue stragglers were formed via collisions) or total mass (as would be expected if all blue stragglers were formed via the unhindered evolution of a s

BACKGROUND: The aim of the study was to evaluate how well vascular function is retained in a cadaver kept in a room with a temperature of 21 degrees C. METHODS: The aorta and pulmonary artery of rats were investigated in organ baths as fresh controls and after 1, 2, 3, or 6 hours' storage in the cadaver. Six-hour-old cadaver aortas were transplanted and investigated after 24 hours and 60 days. RES

Purpose: To evaluate the short-term feasibility, efficacy, and safety of a modular bifurcated stent-graft with an internal iliac artery (IIA) side branch for endovascular repair of aortoiliac aneurysms. Methods: Between 2002 and 2005, 10 male patients (median age 75 years, range 59–83) were treated with a bifurcated stent-graft that included a unilateral side branch for the IIA. The median diamet

Man har gett namnet ”vitalister” till de tänkare som tillskriver den levande materian en särskild status. Den särskilda statusen kräver vissa uppoffringar. Vitalismen är tvungen att erkänna ett orsaksbegrepp som avviker markant från det dominerande mekanistiska modellen i det modernistiska programmet. Den vitala ”kraften” eller ”principen”, agerar genom den organiska vävnaden för att orsaka den rö

ETS gene fusions have been characterized in a majority of prostate cancers; however, the key molecular alterations in ETS-negative cancers are unclear. Here we used an outlier meta-analysis (meta-COPA) to identify SPINK1 outlier expression exclusively in a subset of ETS rearrangement-negative cancers (similar to 10% of total cases). We validated the mutual exclusivity of SPINK1 expression and ETS
