Cyclic RGD peptides are well-known ligands of integrins. The integrins αVβ3 and α5β1 are involved in angiogenesis, and integrin αVβ3 is abundantly present on cancer cells, thus representing a therapeutic target. Hence, synthetic and biophysical studies continuously are being directed towards the understanding of ligand-integrin interaction. In this context, the development of versatile synthetic s
Flavin-dependent halogenases regioselectively introduce halide substituents into electron-rich substrates under mild reaction conditions. For the enzyme Xcc4156 from Xanthomonas campestris, the structure of a complex with the cofactor flavin adenine dinucleotide (FAD) and a bromide ion would be of particular interest as this enzyme exclusively brominates model substrates in vitro. Apo Xcc4156 crys
The phytochemical exploration of the Entandrophragma candollei stem bark extract led to the isolation and identification of twenty compounds including three undescribed phragmalin-class limonoids named encandollens C–E (1–3), the undescribed protolimonoid 5 together with sixteen known compounds. The structures of all the isolated compounds were determined by interpretation of their spectroscopic a
Halogen substituents often lead to a profound effect on the biological activity of organic compounds. Flavin-dependent halogenases offer the possibility of regioselective halogenation at non-activated carbon atoms, while employing only halide salts and molecular oxygen. However, low enzyme activity, instability, and narrow substrate scope compromise the use of enzymatic halogenation as an economic
This article examines the idea of degrowth, a concept in political ecology used to envision a democratically planned downscaling of production and consumption in affluent regions of the world as a means to avoid ecological breakdown, decrease inequality, and improve quality of life. Since its inception at the beginning of the 2000s in France, the idea of degrowth has sparked a worldwide social mov
The purpose of this study is to explore the concept of social acceleration by examining how cities are trying to speed up, maintain or slow down the pace of societal change. Through studies of cycle logistics policies and actions in cities in Denmark, Norway, the UK, the Netherlands, and Germany, we show how these balance between acting as pace-makers and pace-takers, as well as what the consequenThe purpose of this study is to explore the concept of social acceleration by examining how cities are trying tospeed up, maintain or slow down the pace of societal change.

Meeting the goals set out in the Paris Agreement will require rapid and deep reductions of greenhouse gas emissions (GHG) across all sectors of the global economy. Like all major societal transformations, this climate transition will impact both social and technical aspects of society and, depending on how it evolves, will reallocate social and economic benefits and costs differently. Recognising
[4Fe–4S] clusters are essential cofactors in many proteins involved in biological redox-active processes. Density functional theory (DFT) methods are widely used to study these clusters. Previous investigations have indicated that there exist two local minima for these clusters in proteins. We perform a detailed study of these minima in five proteins and two oxidation states, using combined quantu
Den här boken behandlar offentlig upphandling från ett juridiskt och ett nationalekonomiskt perspektiv. Bokens disposition följer i princip upphandlingsprocessen, från behovsidentifiering till avtalsslut. Inledningsvis diskuteras när det är lämpligt att ersätta verksamhet i egen regi med upphandling. Därefter går boken in på hur offentlig upphandling ska genomföras, inom de ramar som ges av regelv
Background & aims: Despite advances in the management of short bowel syndrome related intestinal failure (SBS-IF), large-scale contemporary pediatric studies are scarce. The aim of this multicenter study was to assess key outcomes and clinical prognostic factors in a recent Nordic pediatric SBS-IF population. Methods: Patients with SBS-IF treated during 2010–2019, whose parenteral support (PS)
Ansvaret för att tillhandahålla välfärdstjänster i Sverige ligger i huvudsak på kommuner, landsting och regioner. Det gäller bland annat tillgång till bostäder, hälso- och sjukvård, avfallshantering och utbildning.Utförandet är dock ofta en uppgift för privata aktörer, vilket innebär att det EU-rättsliga regelverket aktualiseras. I den här rapporten diskuterar professor Tom Madell vilken betydelse
