HemaExplorer: a database of mRNA expression profiles in normal and malignant haematopoiesis.

The HemaExplorer (http://servers.binf.ku.dk/hemaexplorer) is a curated database of processed mRNA Gene expression profiles (GEPs) that provides an easy display of gene expression in haematopoietic cells. HemaExplorer contains GEPs derived from mouse/human haematopoietic stem and progenitor cells as well as from more differentiated cell types. Moreover, data from distinct subtypes of human acute my

Reduced forced expiratory volume is associated with increased incidence of atrial fibrillation: the Malmo Preventive Project.

Reduced forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) have been associated with increased incidence of cardiovascular diseases. However, whether reduced lung function is also a risk factor for incidence of atrial fibrillation (AF) is still unclear. We aimed to determine whether lung function predicted AF in the Malmö Preventive Project, a large population-based coho

Reversible in situ precipitation: a flow-through approach for coating macroporous supports with metal hydroxides

In this study we report on the production of metal-hydroxide-coated macroporous polymers (MHCMPs), which mainly involves a polyacrylamide backbone coated with iron-aluminium double hydroxides. The coating process is fast, occurs using relatively mild reagents at room temperature, and can be repeated multiple times, thus making it a very simple and flexible process. Electron microscopy and energy d

A deglacial palaeomagnetic master curve for Fennoscandia Providing a dating template and supporting millennial-scale geomagnetic field patterns for the past 14 ka

Reconstructions of palaeomagnetic secular variation (PSV) in sediment cores can be compared to well-dated regional PSV master curves to infer deposition age. The existing PSV master curve for Fennoscandia, "Fennostack" (Snowball et al., 2007), is limited to the past 10 ka. In this study, we construct a deglacial (for the interval 14-11 ka) PSV master curve for Fennoscandia by including data from a

Role of phosphodiesterases in the shaping of sub-plasma-membrane cAMP oscillations and pulsatile insulin secretion

Specificity and versatility in cyclic AMP (cAMP) signalling are governed by the spatial localisation and temporal dynamics of the signal. Phosphodiesterases (PDEs) are important for shaping cAMP signals by hydrolyzing the nucleotide. In pancreatic beta-cells, glucose triggers sub-plasma-membrane cAMP oscillations, which are important for insulin secretion, but the mechanisms underlying the oscilla

Renormalization and additional degrees of freedom within the chiral effective theory for spin-1 resonances

We study in detail various aspects of the renormalization of the spin-1 resonance propagator in the effective field theory framework. First, we briefly review the formalisms for the description of spin-1 resonances in the path integral formulation with the stress on the issue of propagating degrees of freedom. Then we calculate the one-loop 1(--) meson self-energy within the resonance chiral theor

Fingertip-to-Floor Test and Straight Leg Raising Test: Validity, Responsiveness, and Predictive Value in Patients With Acute/Subacute Low Back Pain.

OBJECTIVES: To investigate the validity over time of the fingertip-to-floor test (FTF) and the straight leg raising test (SLR) using the Roland Morris Disability Questionnaire (RMDQ) and correlation coefficient (r), and to assess the predictive value of factors related to the change in RMDQ over 12 months using multivariate regression analysis. DESIGN: Longitudinal study. SETTING: Outpatient

Threshold Insurance Voting in PR Systems: A Study of Voters’ Strategic Behavior in the 2010 Swedish General Election

This study investigates strategic voting for small parties in proportional representation systems, in previous work sometimes referred to as threshold insurance voting (Cox, 1997). Starting from theories of rational voting (Downs, 1957), three conditions for threshold insurance voting are developed: the voter considers potential government outcomes, votes for a party at risk of falling below an el

Three new species of Achrysocharoides Girault (Hymenoptera: Eulophidae) parasitoids of Phyllonorycter spp. (Lepidoptera: Gracillariidae) on Acer platanoides and Robinia pseudoacacia

Three new species of Achrysocharoides are described, one from northern Europe, A. platanoidae sp. nov., one from central Europe and the U. S. A., A. robiniae sp. nov., and one from the U. S. A., A. robinicolus sp. nov. The descriptions are based on material reared from microlepidopterans of the genus Phyllonorycter Hubner (Gracillariidae): A. platanoidae from P. platanoidella (Joannis) on Acer pla

Search for New Phenomena in Dijet Angular Distributions in Proton-Proton Collisions at root s=8 TeV Measured with the ATLAS Detector

A search for new phenomena in LHC proton-proton collisions at a center-of-mass energy of root s = 8 TeV was performed with the ATLAS detector using an integrated luminosity of 17.3 fb(-1). The angular distributions are studied in events with at least two jets; the highest dijet mass observed is 5.5 TeV. All angular distributions are consistent with the predictions of the standard model. In a bench

The emerging complexity of gene fusions in cancer.

Structural chromosome rearrangements may result in the exchange of coding or regulatory DNA sequences between genes. Many such gene fusions are strong driver mutations in neoplasia and have provided fundamental insights into the disease mechanisms that are involved in tumorigenesis. The close association between the type of gene fusion and the tumour phenotype makes gene fusions ideal for diagnost

Effect of T68A/N126Y mutations on the conformational and ligand binding landscape of Coxsackievirus B3 3C protease.

3C protease of Coxsackievirus B3 (CVB3) plays an essential role in the viral replication cycle, and therefore, emerged as an attractive therapeutic target for the treatment of human diseases caused by CVB3 infection. In this study, we report the first account of the molecular impact of the T68A/N126Y double mutant (MutantBound) using an integrated computational approach. Molecular dynamics simulat

Comparing student learning experiences of in-text commentary and rubric-articulated feedback: strategies for formative assessment

This study compares students' experiences of two types of criteria-based assessment: in text commentary and rubric-articulated feedback, in an assessment design combining the two feedback channels. The main aim is to use students' responses to shed light on how feedback strategies for formative assessment can be optimised. Following action research methodology, the study discusses key categories o

Biorefineries- A Path to Sustainability?

Biorefining of crops for production of power, transport fuels, and a diverse array of chemicals has potential for providing significant added economic value to biomass. A shift in the industrial resource base from fossil resources to biomass also requires a shift in the technology base for producing, handling, and processing of raw materials. Biotechnology will play an important role in providing

Stress and strain provide positional and directional cues in development.

The morphogenesis of organs necessarily involves mechanical interactions and changes in mechanical properties of a tissue. A long standing question is how such changes are directed on a cellular scale while being coordinated at a tissular scale. Growing evidence suggests that mechanical cues are participating in the control of growth and morphogenesis during development. We introduce a mechanical

γ-Aminobutyric acid (GABA) signalling in human pancreatic islets is altered in type 2 diabetes.

AIMS/HYPOTHESIS: γ-Aminobutyric acid (GABA) is a signalling molecule in the interstitial space in pancreatic islets. We examined the expression and function of the GABA signalling system components in human pancreatic islets from normoglycaemic and type 2 diabetic individuals. METHODS: Expression of GABA signalling system components was studied by microarray, quantitative PCR analysis, immunohi

Robust isolation of malignant plasma cells in multiple myeloma.

Molecular characterization of malignant plasma cells is increasingly important for diagnostic and therapeutic stratification in multiple myeloma (MM). However, the malignant plasma cells represent a relatively small subset of bone marrow cells, and need to be enriched prior to analysis. Currently, the cell surface marker CD138 (SDC1) is used for this enrichment, but has an important limitation in
