Condensation of 1-cyanomethyl-2,3,3-trimethyl-3H-indolium perchlorate with ortho-hydroxy-substituted aromatic aldehydes afforded 1-cyanomethylindoline spiropyrans. The latter underwent rearrangement to bridged 1,3-benzoxazepino[3,2-a]indoles on treatment with a base. The mechanism of the rearrangement includes generation of a carbanion stabilized by a cyano Group.
Low-dimensional semiconductors offer interesting physical phenomena but also the possibility to realize novel types of devices based on, for instance, ID structures. By using traditional top-down fabrication methods the performance of devices is often limited by the quality of the processed device structures. In many cases damage makes ultra-small devices unusable. In this work we present a recent
Nontypeable Haemophilus influenzae (NTHi) is a common cause of respiratory tract infections. This study investigated the ability of NTHi to bind lipopolysaccharide-binding protein (LBP) derived from respiratory epithelial cells and the subsequent stimulation of transfected cells expressing membrane-bound CD14 and toll-like receptor 2 (TLR2) or TLR4. In the absence of LBP, NTHi at high concentratio
Popular Abstract in Swedish Denna avhandling är resultatet av mitt doktorandarbete vid Kvartärgeologiska avdelningen, Geologiska institutionen, Lunds universitet. Avhandlingen baseras på resultaten av fältarbeten i ett antal lokaler i ett område väster om sjön Bolmen i sydvästra Sverige. Introduktion och bakgrund Weichselistidens recession från södra Sverige har diskuterats av olika geologer undeThe Late Weichselian deglaciation of an area in southwestern Sweden was reconstructed by geomorphological, sedimentological and lithostratigraphical methods. The morainic deposits were mapped and classified into three landsystems: Streamlined terrain, hummocky moraine and cover moraine. Streamlined terrain was assumed to have been formed subglacially by a wet-based ice sheet. Cover moraine was int
Popular Abstract in Swedish Avhandlingens mål är att undersöka relationen mellan mentala representationer – ‘konceptuella strukturer’ – och deras språkliga form. En sådan undersökning förutsätter en analys inte bara av utomspråkliga representationsnivåer utan även av nivåer som är i sig språkliga. Komplexiteten i förhållandet mellan konceptuella strukturer och den språkliga formen är uppenbar på dThe aim of this thesis is to investigate the relation between intrasubjective mental representations – ‘conceptual structures’ – and their intersubjectively available material manifestation, in particular morphosyntactic representations. Such an investigation presupposes the analysis of not only extralinguistically established modules but also of structural levels that are inherent components of t
District heating is well expanded in the residential areas in Sweden, although not in detached house areas. Increased environmental concerns as well as steadily increasing electricity and oil prices make the detached houses sector a potential market for the district heating companies. District heating in low heat density areas is economically challenging for mainly two reasons: Firstly, constructi
Objective: The aim of this study was to assess the ability of a single 24-h dietary recall (24HDR) and food questionnaires (FQ) to predict plasma carotenoid levels at the ecological level by assessing the relationship between mean plasma carotenoid levels and mean intake of fruit and vegetables measured by 24HDR and FQ across 16 European regions. Design: A random subsample of 3089 subjects was inc
We study dissipative properties of the motion of a slow nuclear collective variable weakly coupled to a complex quantum environment formed by the fast nucleonic degrees of freedom. The fast quantum mechanical subsystem is treated within the random matrix approach, where the complexity of the nucleonic degrees of freedom's motion can be changed by a parameter from regular to fully chaotic.

OBJECTIVE—Glucagon-like peptide 1 (GLP-1) is an incretin that augments insulin secretion after meal intake and is developed for treatment of type 2 diabetes. As a novel therapeutic agent, characteristics of its β-cell effects are important to establish. Previously, β-cell effects of GLP-1 have been characterized in humans during graded intravenous infusions of glucose, whereas its effects after mo
To increase the pace of development and deployment of new services and applications in telecommunication networks, new service architectures have been proposed. Parlay/OSA is one of the proposals that has aroused most attention. By providing network functionality via Application Program Interfaces (APIs), Parlay/OSA facilitates creation of telecommunication services and applications for independen

Oxidation of coproporphyrinogen III to coproporphyrin III is found in extracts of Escherichia coli cells containing the Bacillus subtilis HemY protein (M. Hansson and L. Hederstedt, J. Bacteriol. 176, 5962-5970). We have analysed whether this activity is due to the heterologous expression system, since it in vivo would lead to disruption of the heme biosynthetic pathway. B. subtilis hemY was fused
