The single amino acid mutation G26R in human apolipoprotein A-I (apoA-IIOWA) leads to the formation of beta-secondary structure rich amyloid fibrils in vivo. Here we show that full-length apoA-IIOWA has a decreased lipid-binding capability, an increased amino-terminal sensitivity to protease, and a propensity to form annular protofibrils visible by electron microscopy. The molecular basis for the
In plants the chloroplast thylakoid membrane is the site of light-dependent photosynthetic reactions coupled to ATP synthesis. The ability of the plant cell to build and alter this membrane system is essential for efficient photosynthesis. A nucleotide translocator homologous to the bovine mitochondrial ADP/ATP carrier (AAC) was previously found in spinach thylakoids. Here we have identified and c
Apolipoprotein A-I (apoA-I) is the major protein constituent of high density lipoprotein (HDL) and plays a central role in phospholipid and cholesterol metabolism. This 243-residue long protein is remarkably flexible and assumes numerous lipid-dependent conformations. Consequently, definitive structural determination of lipid-free apoA-I in solution has been difficult. Using electron paramagnetic
The Pho84 high-affinity phosphate permease is the primary phosphate transporter in the yeast Saccharomyces cerevisiae under phosphate-limiting conditions. The soluble G protein, Gtr1, has previously been suggested to be involved in the derepressible Pho84 phosphate uptake function. This idea was based on a displayed deletion phenotype of Deltagtr1 similar to the Deltapho84 phenotype. As of yet, th
The phosphate transporter Pho84 of Saccharomyces cerevisiae is predicted to contain 12 transmembrane (TM) regions, divided into two partially duplicated parts of 6 TM segments. The three-dimensional (3D) organization of the Pho84 protein has not yet been determined. However, the 3D crystal structure of the Escherichia coli MFS glycerol-3-phosphate/phosphate antiporter, GlpT, and lactose transporte
In Saccharomyces cerevisiae, the Pho84 high-affinity transport system is the major phosphate transporter activated when the cells experience a limitation in external phosphate. In this study, we have compared the phosphate-responsive mechanism of cells expressing PHO84 with a Deltapho84 strain by use of a phosphate analogue, methylphosphonate, which was judged to be suitable for assessment of phos
Membrane transport systems active in cellular inorganic phosphate (P(i)) acquisition play a key role in maintaining cellular P(i) homeostasis, independent of whether the cell is a unicellular microorganism or is contained in the tissue of a higher eukaryotic organism. Since unicellular eukaryotes such as yeast interact directly with the nutritious environment, regulation of P(i) transport is maint
A widely accepted mechanism for selective degradation of plasma membrane proteins is via ubiquitination and/or phosphorylation events. Such a regulated degradation has previously been suggested to rely on the presence of a specific SINNDAKSS sequence within the protein. Modification of a partly conserved SINNDAKSS-like sequence in the C-terminal tail of the Pho84 phosphate transporter, in combinat
The derepressible Pho84 high-affinity phosphate permease of Saccharomyces cerevisiae, encoded by the PHO84 gene belongs to a family of phosphate:proton symporters (PHS). The protein contains 12 native cysteine residues of which five are predicted to be located in putative transmembrane regions III, VI, VIII, IX, and X, and the remaining seven in the hydrophilic domains of the protein. Here we repo
In 2015 Afghans were the second largest group of asylum seekers in Sweden (and Europe). In this article, I analyze interviews conducted in early 2017 in Scania County with six adult male Afghan asylum seekers, an executive officer at the Swedish Migration Agency, the head of a private asylum seeker camp, and a voluntary worker. I show how the asylum seekers made their way to Sweden not so much thr
A full-scale inside out hollow fibre membrane module was operated in a pilot-scale water treatmentplant in Sweden for a period of 12 months from August 2013 to July 2014. Liquid chromatography–organic carbon detection (LC-OCD) chromatogram indicated the membranes could effectivelyremove 86% of dissolved organic carbon and 92% of humic substances from the feedwater.

Abstract A superpixel based tracker is tested on the two Tracking sequences from PDTV [7], Minsk and Sherbrooke. It detects all vehicles from the Minsk dataset although a few of them are splitted. The pedestrians are too small and thus all missed. The results for the Sherbrooke are not as good, especially in the areas far way from the camera where the intersection s viewed at a low angle. Also the
Abstract in Bosnian:Raširenost vladajućih normi u društvu u kontekstu rata, okupacije, anarhije i preuzimanja vlasti od strane kriminalnih snaga uništava stare, ali postavlja nove norme, koje takođe mogu biti odbačene. Anomija se može opisati kao nukleus društva, kao vrsta „pulsirajuće moralne destrukcije” koju niko ne kontroliše, ali koja paradoksalno proizvodi socijalni red. Anomija se ne rađa i
Kapitlet skärskådar begreppet ”det civila samhället”. Det beskriver hur det historiskt har tillskrivits olika betydelser, vilket naturligtvis vållat debatt! Kapitlet diskuterar hur civilsamhället och det sociala arbetet förhåller sig till varandra både historiskt och begreppsligt. Den svenska välfärdsstatens utveckling och det civila samhällets roll behandlas både genom att synliggöra hur utveckli
Kapitlet presenterar en omfattande kvantitativ studie av det organiserade civila samhället i Sverige som genomförts genom en enkätstudie riktad till organisationer aktiva inom det sociala området. Mer än 1700 organisationers aktiviteter, resurser och finansiering samt hur de upplever relationen med det offentliga analyseras med hjälp av resultaten från enkäten. Resultaten jämförs med och diskutera
This study investigates the impact of an intervention of playful improvisational theater on organizational creativity. Teams from 9 participating organizations (N = 93) completed pre- and posttest measures of adult playfulness, workplace playfulness, individual creativity, group creativity, and psychological safety. Group creativity was assessed with the newly developed test Distributed Creativity
