Leucocyte recruitment and molecular fortification of keratinocytes triggered by streptococcal M1 protein

Streptococcus pyogenes of the M1 serotype is commonly associated with invasive streptococcal infections and development of streptococcal toxic shock syndrome. The M1 protein is a powerful inducer of inflammatory responses for several human cell types, but the reason why M1 protein-related strains is over-represented in invasive streptococcal diseases is still not understood. This study was underta

A chronology of environmental changes in the Lake Vättern basin from deglaciation to its final isolation

During and after deglaciation, Lake Vättern developed from a proglacial lake situated at the westernmost rim of the Baltic Ice Lake (BIL), into a brackish water body connecting the North Sea and the Baltic Sea, and finally into an isolated freshwater lake. Here we present geochemical and mineralogical data from a 70-m composite sediment core recovered in southern Lake Vättern. Together with a radi

SAXS and stability studies of iron-induced oligomers of bacterial frataxin CyaY

Frataxin is a highly conserved protein found in both prokaryotes and eukaryotes. It is involved in several central functions in cells, which include iron delivery to biochemical processes, such as heme synthesis, assembly of iron-sulfur clusters (ISC), storage of surplus iron in conditions of iron overload, and repair of ISC in aconitase. Frataxin from different organisms has been shown to undergo

Dialog öppnar vägen för visare styrning

I kapitlet diskuteras de styrningsideal som råder i kommunal verksamhet och hur dessa påverkats av New Public Management – den styrningsfilosofi som växte sig stark under 1990-talet och i början av 2000-talets första decennium. Ramberg noterar dels det märkliga i att styrverktyg utvecklade för att hantera företagsvärldens utmaningar alls prövas i kommunal verksamhet, dels det anmärkningsvärda i at

Tracking the evolution of causal cognition in humans

We suggest a seven-grade model for the evolution of causal cognition as a framework that can be used to gauge variation in the complexity of causal reasoning from the panin-hominin split until the appearance of cognitively modern hunter-gatherer communities. The intention is to put forward a cohesive model for the evolution of causal cognition in humans, which can be assessed against increasingly

Urban and peri-urban family-based pig-keeping in Cambodia : Characteristics, management and perceived benefits and constraints

Keeping pigs in urban and peri-urban areas may not only provide many benefits for the urban households, but may also be challenging and a potential health hazard. The aim of this cross-sectional study was to describe household characteristics and to evaluate perceived benefits and constraints among pig-keepers in the urban and peri-urban areas of Phnom Penh, Cambodia. The study included 204 househ

Whole grain cereal products and baseline gut microbiota composition in metabolic and appetite regulation in healthy humans - Emphasizing rye and barley

The prevalence of obesity, type 2 diabetes (T2D) and cardiovascular disease (CVD) is increasing continuously worldwide. These metabolic diseases are associated with many health issues, including increased risk of depression and cognitive impairment. Whole grain (WG) has shown potential to prevent obesity, T2D and CVD. One mechanism can be related to gut fermentation of specific indigestible carboh

Interaction of polymer-coated gold nanoparticles with cellobiose dehydrogenase : The role of surface charges

Studying the interaction of functional proteins such as enzymes and nanoparticles (NPs) includes the important topic of investigating any possible changes in stability and function of enzymes in nanostructured environments. The effects of NPs on the enzyme activity and stability are governed by their physical and chemical properties such as structure, shape, size, surface chemistry and their surfa

Widespread Increases in Iron Concentration in European and North American Freshwaters

Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given the fundamental role of Fe in biogeochemical processes. Still, little is known about the frequency and geographical distribution of Fe trends or about the underlying drivers. We analyzed temporal trends of Fe concentrations across 340 water bodies distributed over 10 countries in northern Europe and North Am

Biomass to transform the chemical industry

The advances that have been made in metabolic engineering of various host organisms today enables a growing number of chemical compounds to be produced from sugars, rather than petroleum. Some of these products, such as propanediol, and lactic and succinic acid, are reaching commercial-scale production.

Bridging the gap between academic cultures of teaching : Ethics, Particularity and Interdisciplinarity in Academic Development Programmes

The purpose of this article is to construct an ethical position of Academic Development Programmes where managerial, top-down principles, are rejected because of the disciplinary resistance such positions bring in the reluctance of recognising existing teaching practices. Instead a focus on particularity through the acceptance of professional difference in an interdisciplinary dialogue is put forw

Didactic Reasoning in Academic Teacher Development : Towards a New Understanding of Teacher Training for Academics

Academic teacher development is an educational meeting place for academics already practising the art of teaching. Yet, it is in courses for this development that academics are supposed to be taught how to teach and how to improve their teaching skills. In my article I propose a new conceptual methodological framework for teaching teachers how to teach – Didactic Reasoning. Its foundation can be t
