We report new data on the abundance and distribution of n-monocarboxylic acids (n-MCAs) in fine- and coarse-mode aerosols in rural and urban areas of Sweden, and determine their possible sources. Overall, C-6-C-16 n-MCAs accounted for similar to 0.5-1.2% of the total PM10 (particulate matter 75%), with the exception of wintertime samples from a rural site, where C-6-C-11 acids accounted for 65% of

The first two studies aiming for the high-throughput identification of the somatic mutation spectrum of colorectal cancer (CRC) tumors were published in 2006 and 2007. Using exome sequencing, they described 69 and 140 candidate cancer genes (CAN genes), respectively. We hypothesized that germline variants in these genes may influence CRC risk, similar to APC, which is causing CRC through germline

The rapid rise of an innovative private manufacturing economy in China challenges standard economic explanations of growth, which typically assume the existence of well-defined formal institutions such as property rights and company laws safeguarding investor and creditor interests. We highlight the social structure of cooperation that enables innovative activity in private manufacturing firms whe

In much of preindustrial Europe the manorial estate was an important institution in the rural economy. Despite a widespread view that the estates insured its tenants against uncertainties, there is little evidence that measures taken were efficient. This study uses the impact of grain prices on demographic outcomes as a measure of the efficiency of the manorial system in protecting its inhabitants

Dobutamine is a cardiotonic agent, developed as a racemate more than 30 years ago. The compound soon got the label "the beta 1-selective adrenoceptor agonist''. However, a closer examination of the enantiomers showed that (+)-dobutamine is predominantly a beta(1)- and beta(2)-adrenoceptor agonist with modest selectivity whereas (-)-dobutamine is predominantly an alpha(1)-adrenoceptor agonist. Neve

In the present study, we compare modern and Quaternary ostracods from two lacustrine basins: Laguna Cari-Laufquen (41 degrees S) and Lago Cardiel (49 degrees S) in Patagonia. Taxonomic and quantitative analyses along with isotopic and chemical studies of the extant ostracod fauna indicate that distinct ostracod associations can be identified as a function of conductivity. Three ostracod associatio

Global environmental changes and human activity influence wildland fires worldwide, but the relative importance of the individual factors varies regionally and their interplay can be difficult to disentangle. Here we evaluate projected future changes in burned area at the European and sub-European scale, and we investigate uncertainties in the relative importance of the determining factors. We sim

Based on the randomised Euro-EWING99-R1 trial, vincristine, adriamycin, cyclophosphamide (VAC) may be able to replace vincristine, adriamycin, ifosfamide (VAI) in the treatment of standard-risk Ewing sarcoma. However some heterogeneity of treatment effect by gender was observed. The current exploratory study aimed at investigating the influence of gender on treatment efficacy and acute toxicity.

In this study well-ordered glycerol monooleate (GMO)-based cubic liquid crystalline nanoparticles (LCNPs) have been used as substrates for Thermomyces lanuginosus lipase in order to establish the relation between the catalytic activity, measured by pH-stat titration, and the change in morphology and nanostructure determined by cryogenic transmission electron microscopy and synchrotron small angle

The article reports and discusses a long-term qualitative study of forty 8-10 year old students who regularly played a math game during math lessons for 9 weeks. The goal was to explore the relations between (i) some of the pedagogical principles that underlie the game and (ii) the playing practice in terms of what actually takes place when students play the math game during regular math lessons.

We report how the three-dimensional structure of subcutaneous injections of soluble insulin can be visualized by x-ray computed tomography using an iodine based contrast agent. The injections investigated are performed ex vivo in porcine adipose tissue. Full tomography scans carried out at a laboratory x-ray source with a total acquisition time of about 1 min yield CT-images with an effective pixe

Allogeneic transplantation after reduced intensity conditioning (allo-RIC) is a treatment option for patients with Hodgkin's lymphoma (HL) relapsing after autologous transplantation. In all, 23 adult patients with HL underwent allo-RIC in Sweden between 2000 and 2007. The median number of previous treatment lines was five and 20 patients (87%) were previously autografted. TRM at 100 days and at 1

The wheat pathogen Stagonospora nodorum, causal organism of the wheat disease Stagonospora nodorum blotch, has emerged as a model for the Dothideomycetes, a large fungal taxon that includes many important plant pathogens. The initial annotation of the genome assembly included 16 586 nuclear gene models. These gene models were used to design a microarray that has been interrogated with labelled tra

We show that the formation of the wetting layer and the experimentally observed continuous shift of the H2O-OH balance toward molecular water at increasing coverage on a TiO2(110) surface can be rationalized on a molecular level. The mechanism is based on the initial formation of stable hydroxyl pairs, a repulsive interaction between these pairs, and an attractive interaction with respect to water

It is well-known that clay can form lamellar structures i.e. tactoids, and recently it has been shown that the tactoid formation is dependent on the platelet diameter. To the authors knowledge, no tactoid formation has been observed for montmorillonite platelets with a diameter less than 60nm. In this study, small angle X-ray scattering in combination with coarse-grained modeling and molecular dyn

Establishing a tractable yet complete reaction coordinate for the spin-state interconversion in d(4)-d(7) transition metal complexes is an integral aspect of controlling the dynamics that govern their functionality. For spin crossover phenomena, the limitations of a single-mode approximation that solely accounts for an isotropic increase in the metal-ligand bond length have long been recognized fo
