Aerosols are one of the significant factors influencing climate, environment, and human health. They are categorized into anthropogenic and natural sources. In Sweden, natural aerosol sources of high coarse mode particle mass concentrations for particles larger than 1 µm in diameter include sea spray, primary biogenic particles, and dust particles. The dust particles can be agricultural soil and m
The existence of consistent individual differences in behaviour ('animal personality') has been well documented in recent years. However, how such individual variation in behaviour is maintained over evolutionary time is an ongoing conundrum. A well-studied axis of animal personality is individual variation along a bold-shy continuum, where individuals differ consistently in their propensity to ta
BACKGROUND: Immigrant women in Sweden have lower levels of leisure time physical activity (LTPA) than Swedish-born women. The reasons are unclear, although acculturation has been suggested to play a role. METHODS: We used a cross-sectional study design to investigate the association between LTPA and two indicators of acculturation: (i) language proficiency (ability to understand news reports on th
In approximately 70% of individuals infected with HIV-1 subtype B, the virus switches coreceptor use from exclusively CCR5 use (R5 virus) to either inclusion of or exclusively CXCR4 use (X4 virus) during infection. This switch is associated with an accelerated loss of CD4(+) T-cells and a faster progression to AIDS. Despite intensive research, the mechanisms responsible for coreceptor switch remai
This paper draws on Jean–Luc Marion's notion of non–objective phenomena to discuss the difficulty of studying leadership. Marion conceptualises non–objective phenomena as phenomena that cannot be captured by scientific methods. Attempts to do so result in a poor understanding of the phenomenon as it gives itself. Put differently: non–objective phenomena remain invisible to the gaze of the research
Nodal involvement is the most important prognostic factor in colon cancer. Although theoretically appealing, it is not known if wider mesenteric excision improves the oncological result. The aim of this retrospective study was to investigate whether wider mesenteric excision yields a superior oncological result.
Streptococcus pyogenes, also known as Group A Streptococcus (GAS), is an important human bacterial pathogen that can cause invasive infections. Once it colonizes its exclusively human host, GAS needs to surmount numerous innate immune defense mechanisms, including opsonization by complement and consequent phagocytosis. Several strains of GAS bind to human-specific complement inhibitors, C4b-bindin
We previously discovered that high copeptin is associated with incidence of diabetes mellitus (diabetes), abdominal obesity, and albuminuria. Furthermore, copeptin predicts cardiovascular events after myocardial infarction in diabetic patients, but whether it is associated with heart disease and death in individuals without diabetes and prevalent cardiovascular disease is unknown. In this study, w
The c-myc proto-oncogene was analyzed in 311 cases of primary breast cancer, in 8% of which it was found to be amplified, usually at moderately increased copy number (2-5 copies). The adjacent pvt gene was co-amplified with c-myc in all tumors analyzed. C-myc amplification was significantly correlated to a high S-phase fraction and to amplification of the c-erbB-2 proto-oncogene. Weak relationship
Low-density polethylene disks with smooth or course surfaces were implanted in the abdominal wall of rats, and the tissue response was evaluated after 1, 6, or 12 weeks. Cell damage was detected by two different methods. Cells with increased membrane permeability could be identified using fluorescence microscopy by injection of propidium iodide prior to the killing of the rats. Second, cell death
It has been known for more than a century that neoplastic cells often exhibit disturbances of the mitotic process, but the causes have only recently been thoroughly explored. In many cancers, a combination of cell cycle checkpoint deficiency and abnormal shortening of telomeres predisposes to unbalanced chromosome segregation at cell division and the development of complex genomic rearrangements.
Chlorosis in crops grown on calcareous soil is mainly due to iron (Fe) deficiency and can be alleviated by leaf application of soluble Fe2+ or diluted acids. Whether chlorosis in indigenous plants forced to grow on a calcareous soil is also caused by Fe deficiency has, however, not been demonstrated. Veronica officinalis, a widespread calcifuge plant in Central and Northern Europe, was cultivated
Syftet med detta examensarbete är att undersöka vad som får svenska pensionärer att migrera till Costa del Sol och hur det påverkar deras uppfattning om deras existentiella hälsa som uttryckt i mening-i-livet, sammanhang och tillit. Uppsatsen bygger på ett två veckor långt fältarbete, med observationer, samtal och ett kort frågeformulär. Den övergripande forskningsfrågan är hur migrationen har påvThe purpose of this thesis is to investigate what makes Swedish retirees migrate to Costa del Sol and how it affects their perception of their Existential Health as expressed in Meaning-in-life, Coherence and Trust, building on a two-week fieldwork, with observations, free conversations, and a short questionnaire. The overall research question is how the migration has influenced retiree’s percepti
In 2017 the Upper Secondary School Act [Hereafter gymnasielag/en] was adopted in Sweden and provided temporary residence permits and a chance of permanent residency to ‘unaccompanied refugee minors’ who previously had been denied asylum. This study includes voices of four young people who have managed to fulfil this journey from temporary permits to permanent. Moreover, three people who through va
The purpose of this thesis is to describe the discursive development and to investigate the political consequences of Corporate Social Responsibility (CSR). Since its origins in the United States in the 1950s, CSR has developed into a symbolic powerhouse, affecting corporations, governments and peoples. CSR as a concept provides a convincing common-sense argument: why should the affluent not contr
Can differences in institutional quality explain current account imbalances in the Euro area? This paper emphasizes a link between current accounts and institutional quality based on a country study for Greece. Subsequently it tests the relationship for a homogeneous sample of 24 European countries over the period 1990 through 2013. Regression analysis indicates that institutional quality is cruci
