The conserved ESX-1 type VII secretion system is a major virulence determinant of pathogenic mycobacteria, including Mycobacterium tuberculosis and Mycobacterium marinum. ESX-1 is known to interact with infected macrophages, but its potential roles in regulating other host cells and immunopathology have remained largely unexplored. Using a murine M. marinum infection model, we identify neutrophils

The question of how cooperation evolves and is maintained among nonkin is central to the biological, social, and behavioral sciences. Previous research has focused on explaining how cooperation in social dilemmas can be maintained by direct and indirect reciprocity among the participants of the social dilemma. However, in complex human societies, both modern and ancient, cooperation is frequently

It is now established that native language affects one's perception of the world. However, it is unknown whether this effect is merely driven by conscious, language-based evaluation of the environment or whether it reflects fundamental differences in perceptual processing between individuals speaking different languages. Using brain potentials, we demonstrate that the existence in Greek of 2 color

We analyze public-policy speeches in the Florentine Consulte e Pratiche, immediately prior to the Ciompi Revolt, for signs of elite factional conflict, in the context of self-proclaimed unity. We employ three statistical analyses of these speeches in Latin: namely, scatterplots of word frequencies, Wordfish scaling, and regressions on speech-similarities. Plus we employ two qualitative analyses: a

Feminist Activism in the Post-2010s Sinosphere examines a variety of urgent feminist issues in 21st-century China, including the #MeToo movement, online misogyny, feminism in popular media, and the experiences and rights of queer, trans and ethnic minority groups. The chapters explore shifting dynamics between state feminism, NGO and grassroots movements, the intersection of academia and intellect

Using Jacques Lacan’s theories of subjectivity, this dissertation analyses the relationships between the ideal selves and the romantic desires of characters in Alice Walker’s The Color Purple, Alasdair Gray’s Poor Things and Junot Díaz’s The Brief Wondous Life of Oscar Wao. Lacan argues that there is an inherent lack in all human beings, stemming from incompleteness and early helplessness, and emp

Popular Abstract in Swedish Traditionellt har effekten av behandling inom kärlkirurgi främst utvärderats med objektiva mått, som till exempel beräkning av ankelindex och gångsträcka. Dessa data ger värdefull information men de återger inte hur patientens klarar sitt dagliga liv eller hur behandling återverkar på deras livskvalitet. Detta styrks i tidigare forskning som visar att korrelationen mellThe aim of this thesis was to assess quality of life in patients with varying degrees of lower limb ischaemia before and after revascularisation, to assess quality of life in relation to the degree of ischaemia and the respondents’ sense of coherence (SOC) and in comparison with a healthy control group, and to compare two different quality of life instruments regarding their usefulness as outcome

Popular Abstract in Swedish Huden och slemhinnor (mukosa) fungerar som kroppens skyddsbarriärer mot yttre angrepp av mikrober, makromolekyler och toxiner och förhindrar dessa att nå inre organ. Trots ett massivt immunskydd sker de flesta infektioner på slemhinnornas ytor. I blodcirkulationen förekommer fem olika typer av vita blodkroppar, alla med olika roller i immunförsvaret. I varje blod finns Mucosal infections trigger an inflammatory response that includes the secretion of cytokines and the recruitment of neutrophils to the infected site. This thesis describes studies examining the molecular mechanisms of neutrophil migration to sites of mucosal bacterial infection. Escherichia coli (E. coli) infection of epithelial cell layers stimulates chemokine secretion and chemokine receptor ex

Popular Abstract in Swedish Streptococcus pyogenes (GAS) är en viktig sjukdomsframkallande bakterie som orsakar alltifrån lindriga infektioner som halsfluss (tonsillit) och svinkoppar (impetigo) till livshotande djupa infektioner som nekrotiserande fasceit eller ”Toxic shock syndrom”. På grund av det snabba sjukdomsförloppet i de livshotande infektionerna har streptokockerna fått beteckningen ”mörA distinguishing feature of Streptococcus pyogenes (GAS) is their ability to resist phagocytosis in whole human blood in the absence of type-specific antibodies, a property that is dependent on the expression of the surface associated M proteins. A common characteristic of M proteins is their interaction with a variety of host proteins including the complement regulatory protein factor H (FH) and

HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a tumoricidal complex consisting of partially unfolded protein and fatty acid, and was first identified in casein fractions of human breast milk. The complex can be produced from its pure components through a modified chromatographic procedure where pre-applied oleic acid binds with partially-unfolded alpha-lactalbumin on the stationar

Systemic lupus erythematosus (SLE) is an autoimmune disease involving many organ systems. The cause is not known, but a complex combination of environmental and genetic factors seems to be involved. In SLE upregulation of type I interferons, a hyperactive B-cell response, presence of autoantibodies against modified nuclear components, increased complement consumption, increased apoptosis and decre

Selective immunoglobulin A deficiency is the most common primary immunodeficiency disorder that is strongly overrepresented among patients with celiac disease (CD). IgG antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptides (DGP) serve as serological markers for CD in IgA deficient individuals, although the diagnostic value remains uncertain. The aim of this study was to

Mental health disorders are a rapidly growing public health problem. Despite the fact that lack of trust in the health-care system is considered to be an important determinant of health, there is scarcity of empirical evidence demonstrating its associations with health outcomes. This is the first study which aims to evaluate the association between trust in the health-care system and psychological

Host defense peptides have recently gained much interest as novel anti-infectives owing to their ability to kill bacteria and simultaneously modulate host cell responses. The cationic host defense peptide GKY25 (GKYGFYTHVFRLKKWIQKVIDQFGE), derived from the C terminus of human thrombin, inhibits proinflammatory responses in vitro and in vivo, but the mode of action is unclear. In this study, we sho

Uppsatsens syfte har varit att kritiskt granska den svenska debatten kring DNA-analys för asylsökande barns rätt till familjeåterförening i Sverige och därmed se ifall principen om barnets bästa, definierat i svenska rättsakter, efterföljs. Genom den vägledande domen från Migrationsöverdomstolen den 18 januari 2012 fastslogs att DNA-analys kan användas för att styrka biologiskt släktskap med förälThe aim of this thesis has been to do a critical review on the Swedish debate concerning the use of DNA-tests to secure the rights of asylum-seeking children to be reunited with their families and if the principle of the best interests of the child is followed. The 18th of January 2012, in a precedent ruling, the Swedish Migration Court of Appeal concluded that DNA-test could be used to prove biol

This is the title of my thesis and it focuses rather on a particular “hype” than deals with the so-called information society as such. What is

The human genome sequence encodes fewer proteins than expected, suggesting that one protein can have several functions and adjust their structure to meet different structural demands. Changes in tertiary structure have mostly been associated with disease and the most striking example is the prion protein, which changes from a mixed alpha-helical and beta-sheet conformation to the beta-sheet rich,
