Antigenic diversity in pathogenic microbes can be a result of at least three different processes: diversifying selection by acquired immunity, host–pathogen coevolution and/or host specialization. Here, we investigate whether host specialization drives diversity at ospC (which encodes an immunodominant surface protein) in the tick-transmitted bacterium Borrelia afzelii. We determined prevalence an
Accident prediction models are often used to predict the number of accidents on segments and at intersections in the road network. Most often the models are developed for a total number of crashes for the facility, or crashes by severity. However, the frequency and severity of crashes of different types can be expected to vary with regards to the underlying phenomena that cause them to occur. To b
Feedbacks mechanisms are essential components of our climate system, as they either increase or decrease changes in climate-related quantities in the presence of external forcings. In this work, we provide the first quantitative estimate regarding the terrestrial climate feedback loop connecting the increasing atmospheric carbon dioxide concentration, changes in gross primary production (GPP) asso
This thesis demonstrates the usefulness of sedimentary pigments as biomarkers of environmental change in estuarine systems and as biomarkers in lakes in relation to climate change. These are two fields where sediment pigment records as measured by high-performance liquid chromatography (HPLC) are emerging areas of study. A detailed study was undertaken to examine the effects of different storage o

Cykling är en viktig del av ett hållbart transportsystem. Det bidrar bl.a. till en bättre miljö och förbättrad folkhälsa. Syftet med arbetet är att undersöka vilka faktorer som kännetecknar en bra cykelstad, ur en infrastruktursynpunkt och vilka faktorer som kan leda till ökad cykling. I arbetet intervjuas representanter för kommunerna Lund, Malmö och Helsingborg om vilka infrastrukturella åtgärdeCycling is an important part of a sustainable transport system. It contributes among other things to a better environment and improved public health. The aim of this thesis is to investigate which factors characterize a good cycling city, from an infrastructural point of view, and which factors may lead to increased cycling. In the thesis, representatives of the municipalities of Lund, Malmö and H
Bio-based 5-hydroxymethylfurfural (HMF) serves as an important platform for several chemicals, among which 2,5-furan dicarboxylic acid (FDCA) has attracted considerable interest as a monomer for the production of polyethylene furanoate (PEF), a potential alternative for fossil-based polyethylene terephthalate (PET). This study is based on the HMF oxidizing activity shown by Mycobacterium sp. MS 16
Antibiotic resistance is currently an extensive medical challenge worldwide, with global numbers increasing steadily. Recent data have highlighted wastewater treatment plants as a reservoir of resistance genes. The impact of these findings for human health can best be summarized using a One Health concept. However, the molecular mechanisms impacting resistance spread have not been carefully evalua
Stability is a fundamental property affecting function, activity, and regulation of biomolecules. Stability changes are often found for mutated proteins involved in diseases. Stability predictors computationally predict protein-stability changes caused by mutations. We performed a systematic analysis of 11 online stability predictors' performances. These predictors are CUPSAT, Dmutant, FoldX, I-Mu
Mangroves provide numerous environmental benefits, such as carbon sequestration, water purification, climate change mitigation, and flood and Tsunami impact reduction. Despite these unique advantages, mangroves are threatened by the combined adverse impacts of human activities and climate change. Therefore, it is essential to implement reasonable practices to avoid further degradation of mangroves
Current hemophilia B treatment guidelines recommend routine prophylaxis with factor IX (FIX) replacement products, tailored to maintain plasma activity at levels that will prevent bleeds. However, plasma FIX activity may not be the primary determinant or best indicator of hemostatic efficacy due to its extravascular distribution. FIX replacement therapy has evolved to include extended half-life (E

Methane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. In this thesis, I examine the performance of the three low-cost solid state sensors, Figaro sensors TGS2600-B00, TGS2611-C00 an
The active site of sulfite reductase (SiR) consists of an unusual siroheme–Fe4S4 assembly coupled via a cysteinate sulfur, and serves for multi-electron reduction reactions. Clear explanations have not been demonstrated for the reasons behind the choice of siroheme (vs. other types of heme) or for the single-atom coupling to an Fe4S4 center (as opposed to simple adjacency or to coupling via chains
Popular Abstract in Swedish Vad är det för något i human mjölk som dödar cancer celler? Kan “fel” veckade proteiner vara nyttiga? Kan fett vara inblandat i protein veckning? Det är några av frågorna som tas upp i denna avhandling. Allt levande består av proteiner som i sin tur är uppbyggda av amino syror. Det finns 20 st. olika amino syror som på olika sätt kan länkas samman till proteinkedjor. DBy varying its secondary or tertiary structure a single protein can attain new biological functions. The amyloid forming proteins are the best known examples where a change in conformation leads to the formation of amyloid fibrils that accumulate in tissues and cause disease. a-lactalbumin in contrast, is an example of a protein that acquires a beneficial function when the conformation is altered
The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. Three methods with different structural complexity were used to estimate the adverse effects of SO2 concentrations in northern Czech R
Popular Abstract in Swedish Den cancerskyddande genen p53 är av betydelse för att göra leukemiceller friska. Blodbildning. Blodceller är nödvändiga för vårt välbefinnande och vår överlevnad. Det finns flera olika typer med egna specialiserade funktioner. Så krävs t. ex. röda blodkroppar för syresättning och vita blodkroppar för att bekämpa infektioner. Blodcellerna har begränsad överlevnad; när Leukemic cells suffer from an impaired ability to differentiate due to inherited or acquired genetic lesions. These genetic changes can sometimes be bypassed with various compounds both in vitro, and, more rarely, in vivo, thus inducing terminal differentiation of the leukemic cells. Differentiation of both leukemic and normal hematopoietic cells is believed to be intimately coupled to cell cycle
Reliable information on solar activity over the Holocene period is important to predict the Sun in the future and to understand the mechanism behind the Sun-climate linkage. Presently, there are discrepancies in the proxy data of solar activity due to reasons that are not yet understood. This leads to major uncertainties in Holocene solar reconstructions. This PhD project aims to improve the Holoc
