Popular Abstract in Swedish Hur gör bakterier för att komma undan immunförsvaret? Vi har studerat hur en vanligt förekommande bakterie, grupp A streptokocker, gör för att undvika kroppens immunförsvar vid infektion. Vi har upptäckt enzymer som bidrar till bakteriens förmåga att undvika immunförsvaret genom att avväpna antikroppar. De bakteriella enzymerna kan användas i bioteknisk industri och eveA majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. In this thesis we aimed at exploring bacterial modulation of host glycosylation in infection and to evaluate the usefulness of bacterial enzymes i

The common human pathogen Streptococcus pyogenes is the causative agent of numerous mild and severe clinical conditions. It expresses a number of secreted or cell wall-anchored proteins that modulate the human immune system and facilitate colonization and spread of the pathogen in the human host. During S. pyogenes infections, human plasma leaks into the site of infection as a consequence of infl

In the equation for thermal energy output from a flat-plate solar collector (written as a function of the collector mean heat carrier temperature), both the gain and the loss terms are multiplied by the collector efficiency factor, F'. For a concentrating collector with an uneven (non-uniform) irradiation on the absorber, the efficiency factor for the gain term, here called the optical efficiency

The M protein of Streptococcus pyogenes is a major bacterial virulence factor that confers resistance to phagocytosis. To analyze how M protein allows evasion of phagocytosis, we used the M22 protein, which has features typical of many M proteins and has two well-characterized regions binding human plasma proteins: the hypervariable NH2-terminal region binds C4b-binding protein (C4BP), which inhib

The M protein family of molecules in the group A streptococcus comprises a number of cell surface proteins that interact with the immune system of the host. One of the proteins in this family is the IgA receptor Arp4, which has C repeats similar to those that characterize the known M proteins. The streptococcal strain expressing Arp4 also expresses a second immunoglobulin-binding protein, Mrp4, wh

Ash is produced in combustion of biomass. Sonic part of this matter is called fly ash and is carried by the flow and causes not only air pollution and erosion, but also call affect the thermal radiation. The effects of fly ash particles oil the thermal radiation are considered ill this investigation. By analyzing sampled data in all electrostatic filter, a realistic particle size distribution is f

Background: Comorbidity impacts overall survival amongst patients with diffuse large B-cell lymphoma (DLBCL). However, associations of comorbidity with lymphoma characteristics, treatment selection and lymphoma-specific mortality are less well known. Objective: To examine the impact of comorbidity on DLBCL characteristics, treatment intent and cause of death. Methods: We identified 3905 adult pati

The nonobese diabetic (NOD) mouse spontaneously develops autoimmune-mediated diseases such as diabetes and Sjögren′s syndrome. To investigate whether NOD genes also promote autoimmune-mediatedarthritis we established a NOD strain with an MHC class II fragment containing the Aq class II gene predisposing for collagen induced arthritis (NOD.Q). However, this mouse was resistant to arthritis in contr

Digital kommunikation medför nya möjligheter för privatpersoner och organisationer att kommunicera. Idag kan de i realtid utbyta information och på så sätt komma närmre sina intressenter. Det är dock oklart hur många som känner till vilken effekt deras digitala kommunikation har. Den här studien undersöker hur kommunala organisationer använder, mäter och utvärderar resultaten av sin digitala kommuDigital communication brings new opportunities for communication between organizations and their stakeholders. Digital channels enable exchange of information in real time and organizations recognize the benefits of having close connections to interested parties. It is however unclear how many organizations that know the effect of their digital communication efforts. This study examines how munici

The “constructivist turn” in International Relations has enhanced our understanding of the power of ideational phenomena such as ideas, norms and identity in world politics . This turn also paved the way for debates on normative power and norm transfer, which have proved to offer fruitful insights into EU normative power and the EU’s identity as an international actor. Exploring the modes of gover

The years 1988-1998 were named by World Council of Churches as The Ecumenical Decade - Churches in Solidarity with Women. On a worldwide scale, the Decade challenged member churches to portray Solidarity with Women in their contexts. Churches around the world launched a variety of projects and programs for this purpose. The Decade envisaged a new fellowship of women and men in church and society,

Two sets of ribosome structures have recently led to two different interpretations of what limits the accuracy of codon translation by transfer RNAs. In this review, inspired by this intermezzo at the Ribosome Club, we briefly discuss accuracy amplification by energy driven proofreading and its implementation in genetic code translation. We further discuss general ways by which the monitoring base

På gående fot färdas man hastigt mellan kontinenterna. Venedigbiennalen är en plats där länder kan se världen och samtidigt synas för världen. Sedan 1895 har Biennalen samlat världens främsta konstnärer och arkitekter. Sverige delar en paviljong med Norge och Finland, vilket innebär konstnärliga kompromisser och att Sveriges enbart deltar var tredje biennal. Examensarbetet föreslår en svensk natiTraveling by foot, one swiftly moves between continents. The Venice Biennale is a place where countries can see the world and, at the same time, be seen by the world. Since 1895, the Biennale has brought together the world’s leading artists and architects. Sweden shares a pavilion with Norway and Finland, which means artistic compromises and Sweden’s participation only every third Biennale. The t
