The purpose of this multicenter study was to determine the accuracy and clinical value of a dedicated breast biopsy system which allows for MR-guided vacuum biopsy (VB) of contrast-enhancing lesions. In five European centers, MR-guided 11-gauge VB was performed on 341 lesions. In 7 cases VB was unsuccessful. This was immediately realized on postinterventional images or direct follow-up combined wi

A series of truncated proteins from a thermostable Bacillus stearothermophilus alpha-amylase was prepared to study the importance of the extension in the C-terminus compared with other liquefying Bacillus alpha-amylases. The mutations introducing new translation termination sites shortened the 515 amino acid residue-long wild type enzyme by 17, 32, 47, 73 or 93 residues, The longer the truncation,

Interactions between the moth Spodoptera littoralis and two of its host plants, alfalfa (Medicago sativa) and cotton (Gossypium hirsutum) were examined, using plants grown under ambient (350 ppm) and elevated (700 ppm) CO2 conditions. To determine strength and effects of herbivore-induced responses assays were performed with both undamaged (control) and herbivore damaged plants. CO2 and damage eff

We review and discuss the importance of correlational selection (selection for optimal character combinations) in natural populations. If two or more traits subject to multivariate selection are heritable, correlational selection builds favourable genetic correlations through the formation of linkage disequilibrium at underlying loci governing the traits. However, linkage disequilibria built up by

Positive patch test reactions to p-phenylenediamine (PPD) are common. PPD is used in oxidative hair dyes and is also present in dark henna temporary 'tattoos'. Cross-sensitization to other contact allergens may occur. Because subjects sensitized to PPD are at risk of clinically severe reactions upon hair dyeing, there is a need for 'current' prevalence data on PPD sensitization. To compare PPD pat

Background Treatment of relapsing-remitting multiple sclerosis with interferon beta is only partly effective, and new more effective and safe strategies are needed. Our aim was to assess the efficacy of oral methylprednisolone as an add-on therapy to subcutaneous interferon beta-1a to reduce the yearly relapse rate in patients with relapsing-remitting multiple sclerosis. Methods NORMIMS (NORdic tr

The recombinant xylose-utilizing Saccharomyces cerevisiae TMB 3399 was constructed by chromosomal integration of the genes encoding Image-xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulokinase (XK). S. cerevisiae TMB 3399 was subjected to chemical mutagenesis with ethyl methanesulfonate and, after enrichment, 33 mutants were selected for improved growth on Image-xylose and carbon dio

We report on a theoretical study of the electronic structure of silicon nanocrystals with a shape of the regular rhombic dodecahedron, based on a tight-binding method. The energies of the lowest unoccupied state and the highest occupied state have been calculated. We have shown that the six-fold degenerate conduction band minima of the bulk silicon crystal are split into a non-degenerate A(1) stat

Laser Doppler velocimetry (LDV) measurement and large eddy simulation (LES) were used to study confined isothermal turbulent swirling flows in a model dump combustor. The aim was to gain deeper understanding of the flow and turbulence structures in dump combustors and to examine the capability of LES for prediction of turbulent swirling flows. A refractive index matching technique is used in the L

The sequence diversity of the entire mitochondrial control region (CR) of three meadow viper (Vipera ursinii) populations was analysed and compared to previously documented nuclear genetic variability at the major histocompatibility complex (MHC) Class I loci. One of the populations, a small and inbred Hungarian population, exhibited no MHC polymorphism, whereas the two other, sampled from large v

The sst1 locus has been identified in a mouse model to control resistance and susceptibility of Mycobacterium tuberculosis infection. Subsequent studies have now identified Ipr1 (intracellular pathogen resistance 1) to be the gene responsible. Ipr1 is encoded within the sst1 locus and is expressed in the tuberculosis lung lesions and macrophages of sst1-resistant, but not sst1-susceptible mice. We

The concept of sustainable development at present permeates public discourse. An inter-organisational perspective can be used to analyse the processes through which this concept has found its way into policy and programme in four different settings: the United Nations, the European Communities, the government of Sweden and the city of Lund, Sweden. Although visible in treaties, laws and action pro

The Pegomya meridiana species group is established for three Palaearctic species that supposedly all as larvae attack seed-capsules of Hypericum spp. (Clusiaceae). Pegomya meridiana (Villeneuve) and P. provecta (Villeneuve) are widespread Eurasian species, while the third species, P. canariensis Michelsen, is endemic to the western Canary Islands. Synapomorphies for the Pegomya meridiana species g

Although clutch size variation has been a key target for studies of avian life history theory, most empirical work has only focused on the ability of parents to raise their altricial young. In this study, we test the hypothesis that costs incurred during incubation may be an additional factor constraining clutch size in altricial birds. In the pied flycatcher (Ficedula hypoleuca), we manipulated t

The crystallization Process in aqueous solutions of the drug bicalutamide and the effect of the polymer polyvinylpyrrolidone (PVP) have been studied. Results showed that PVP decreased the crystallization Fate significantly in a system with PVP concentrations as low as 0.01% (w/w), without changing the polymorph formed. The crystal habit was altered already at PVP concentrations as low as 0.001% (w

This chapter presents a case study from a global company developing a new generation of programmable controllers to replace several existing products. The system needs to incorporate support for a large number of I/O systems, network types, and communication protocols. To leverage its global development resources and the competency of different development centers, the company decided to adopt a c

Lifetime measurements of the metastable 3d D-2(3/2) level in singly charged calcium were performed using the newly developed violet diode laser operated in an external cavity arrangement. The laser was employed on stored ions at the CRYRING facility to optically pump the resonance line at 397 nm. In combination with laser probing at 866 nm this detection scheme gave the possibility to record the l

Denna artikel är en studie av den narrativa metalepsen i två skilda sammanhang: Unamunos roman "Dimma", som publicerades i Spanien i början av 1900-talet, och Chamoiseaus roman "Biblique des derniers gestes", som publicerades i Frankrike på 2000-talet. Studien visar hur användningen av den narrativa metalepsen förändrats under den period på ett hundra år som skiljer de två romanerna, samtidigt somThis article is a study of the metalepsis in two different contexts: Unamuno's novel "Fog", published in Spain at the beginning of the 20th century, and Chamoiseau's novel "Biblique des derniers gestes", published in France in the 21st century. The study shows how the use of narrative metalepsis has changed during the period of one hundred years that separates the novels, but also some surprising
