In the search for new functional ingredients with potential use in the food industry, extracts of unknown species of microalgae, such as Phormidium species have been studied. Three solvents of different polarities (i.e., hexane, ethanol, and water) have been used to obtain pressurized liquid extracts with different compositions. Moreover, extractions were performed at four different extraction tem
Pollinators experience large spatiotemporal fluctuations in resource availability when mass-flowering crops are rotated with resource-poor cereal crops. Yet, few studies have considered the effect this has on pollinator population stability, nor how this might be mitigated to maintain consistent crop pollination services. We assess the potential of boundary features (standard narrow 1 m grassy mar
The objective of this study is to increase the knowledge regarding school principals’ work situations by examining the associations between various factors and the school principals’ assessments of their ability or wish to work until 65 years of age or longer. The 1356 participating school principals in this study were aged between 50 and 64 years of age. Individual and work factors were evaluated
Background aims Human mesenchymal stromal cells (MSC) are promising candidates for cell therapy because of their intriguing properties (high proliferation and differentiation capacity, microenvironmental function and immune modulation). However, MSC are heterogeneous and a better understanding of the heterogeneity of the cells that form the MSC cultures is critical. Methods Human MSC were generate
The nonactivated prothrombin complex concentrate (PCC) Octaplex (Octapharma PPGmbH, Vienna, Austria) has been used successfully for the treatment of congenital and acquired coagulation factor deficiencies and associated bleeding. The aims of this study were to assess retrospectively whether Octaplex is an effective treatment option for haemophilia A patients with high-titre inhibitors of factor VI
Knowledge of which genes and pathways are affected by inbreeding may help understanding the genetic basis of inbreeding depression, the potential for purging (selection against deleterious recessive alleles) and the transition from outcrossing to selfing. Arabidopsis lyrata is a predominantly self-incompatible perennial plant, closely related to the selfing model species A. thaliana. To examine ho
Background: Apart from a consistent focus on treating inflammation, patients with inflammatory arthritis (IA) report a range of unmet needs. Many experience not only residual symptoms but also various other physical, psychological, and social effects. Therefore, this study aimed to develop a complex Interdisciplinary Nurse-coordinated self-management (INSELMA) intervention for patients with IA, as
Popular Abstract in Swedish I Sverige utförs cirka 3500 benamputationer varje år. Över 90% av alla amputationer görs på grund av kärlsjukdomar, där förträngningar i blodkärlen försämrar blodflödet med vävnadsdöd och vanligen kallbrand som följd. Det finns i huvudsak tre faktorer som ökar risken för amputation på grund av kärlsjukdom; ålder *80 år, rökning och diabetes. Om man inte tillhör någon avGeneral characteristics and outcome was evaluated in 177 consecutive patients who underwent a major amputation in a defined population. Smoking and diabetes lowered the mean amputation age. Healing failure at six months was seen in 24% of transtibial and in 11% of transfemoral amputees. Preoperative absence of gangrene and hemoglobin >120 g/L increased the risk of healing failure. Six months after
Recently, Burger et al. (2011) developed a new 1-D SST model which allows for more realistic predictions of the sludge settling behaviour than traditional 1-D models used to date. However, the addition of a compression function in this new 1-D model complicates the model calibration. This study aims to report advances in the calibration of this novel 1-D model. Data of the evolution of the sludge
Popular Abstract in Swedish Globala klimatförändringar, nationell säkerhet och ekonomisk stabilitet är alla starka drivkrafter för utveckling av nya drivmedel. Två intressanta alternativ är vätgas och metangas producerade från förnyelsebara råvaror. Detta kan göras i biologiska processer där bakterier omvandlar socker till vätgas eller metangas. Dessa processer måste dock utvecklas och förbättras A great deal of research is being carried out on the biological production of hydrogen and methane. However, little effort has been devoted to studying the technical and economic feasibility of these processes. The main objective of the work presented in this thesis was to perform techno-economic analyses to improve our understanding of the processes by identifying the bottlenecks, and to provide
Atherosclerosis, the underlying pathology of cardiovascular diseases such as myocardial infarction and ischemic stroke, is characterized by chronic inflammation. T cells are present in atherosclerotic plaques and have been implicated in its pathogenesis. This thesis describes studies exploring both the regulation of T cells in atherosclerosis as well as immunomodulatory therapeutics. To study the
Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links
Objectives: Insufficient sleep is a public health problem that impacts the mental and physical health of children and adolescents. Complaints of insomnia are particularly pervasive among adolescents. This longitudinal study investigates factors that contribute to teen insomnia symptoms. Design: Five-year prospective follow-up study. Setting: School-based. Participants: A total of 522 children (49.
Background- This nationwide study sought to determine age- and gender-specific familial risks in siblings hospitalized for venous thromboembolism (VTE). Methods and Results- The Swedish Multigeneration Register on 0- to 75-year-old subjects was linked to the Hospital Discharge Register for the years 1987-2007. Standardized incidence ratios were calculated for individuals whose siblings were hospit
Pheromone-based monitoring could be a very efficient method to assess the conservation status of rare and elusive insect species, but there are still few studies for which pheromone traps have been used to obtain information on presence, abundance, phenology and movements of such insects. We performed a mark-recapture study of two threatened saproxylic beetles, Osmoderma eremita (Scarabaeidae) and
Selection pressure induced by simultaneously occurring environmental threats is a major evolutionary driver for organisms in terrestrial, as well as in aquatic ecosystems. For example, protection against ultraviolet radiation (UVR) and predation include both morphological and behavioral components. Here we address those selective pressures on zooplankton by performing a latitudinal monitoring, com
Popular Abstract in Swedish De medeltida katedralerna har med sina imponerande stenfasader och höga torn fortsatt att fascinera människor genom århundradena, och silhuetterna utgör fortfarande ett framträdande landmärke för den som närmar sig stiftsstäderna. Även interiörerna vittnar om den medeltida prakten även om, i likhet med exteriörerna, mycket har förändrats och försvunnit sedan dess. Lika The purpose of this thesis is to study the function of the cathedral as a devotional milieu and try to recreate lay people´s visits using the keywords Places, Times, Objects and Motifs. Geographically the study is limited to two cathedrals in present-day Sweden: the ones in Linköping and Lund. In this way, cathedrals from two different ecclesiastical provinces (the archbishoprics of Uppsala and Lu
