Inbreeding affects gene expression differently in two self-incompatible Arabidopsis lyrata populations with similar levels of inbreeding depression.

Knowledge of which genes and pathways are affected by inbreeding may help understanding the genetic basis of inbreeding depression, the potential for purging (selection against deleterious recessive alleles) and the transition from outcrossing to selfing. Arabidopsis lyrata is a predominantly self-incompatible perennial plant, closely related to the selfing model species A. thaliana. To examine ho

Top-down estimates of European CH4 and N2O emissions based on four different inverse models

European CH4 and N2O emissions are estimated for 2006 and 2007 using four independent inverse modelling systems, based on different global and regional Eulerian and Lagrangian transport models. This ensemble approach is designed to provide more realistic estimates of the overall uncertainties in the derived emissions, which is particularly important for verifying bottom-up emission inventories. We

Erythropoietin and Protection of Renal Function in Cardiac Surgery (the EPRICS Trial).

To date, there are no known methods for preventing acute kidney injury after cardiac surgery. Increasing evidence suggests that erythropoietin has renal antiapoptotic and tissue protective effects. However, recent human studies have shown conflicting results. The authors aimed to study the effect of a single high-dose erythropoietin preoperatively on renal function after coronary artery bypass gra

Perceptions and experiences of female genital mutilation after immigration to Sweden: An explorative study

Aim: The aim of this study is to explore how women from part of the world where female genital mutilation (FGM) is normative perceive and experience FGM after immigrating to Sweden. Method: Interviews were conducted with eight women from Djibouti, Eritrea, Ethiopia and Somalia. The data were analyzed using qualitative content analysis. Results: The women's feelings were ambivalent: though they opp

A Large-Scale Test of Free-Energy Simulation Estimates of Protein-Ligand Binding Affinities.

We have performed a large-scale test of alchemical perturbation calculations with the Bennett acceptance-ratio (BAR) approach to estimate relative affinities for the binding of 107 ligands to 10 different proteins. Employing 20-Å truncated spherical systems and only one intermediate state in the perturbations, we obtain an error of less than 4 kJ/mol for 54% of the studied relative affinities and

Doubtful effect of continuous intraarticular analgesia after total knee arthroplasty.

Background and purpose - Local infiltration analgesia (LIA) is well established for effective postoperative pain relief in total knee arthroplasty (TKA). To prolong the effect of LIA, infusion pumps with local intraarticular analgesia can be used. We evaluated the effect of such an infusion pump for the first 48 h postoperatively regarding pain, knee function, length of stay (LOS) in hospital, and

Institutional Objects, Reductionism and Theories of Persistence

Can institutional objects be identified with physical objects that have been ascribed status functions, as advocated by John Searle in The Construction of Social Reality (1995)? The paper argues that the prospects of this identification hinge on how objects persist – i.e. whether they endure, perdure or exdure through time. This important connection between reductive identification and mode of per

The α2β1 binding domain of chondroadherin inhibits breast cancer-induced bone metastases and impairs primary tumour growth: A preclinical study.

cyclicCHAD is a peptide representing the α2β1 integrin binding sequence of the matrix protein chondroadherin (CHAD), which in our hands proved effective at counteracting bone loss in ovariectomised mice by inhibiting osteoclastogenesis. Given that bone metastases are characterised by exacerbated osteoclast activity as well, we tested this therapy in mice intracardiacally injected with the osteotro

Anisotropic diffusive transport: Connecting microscopic scattering and macroscopic transport properties

This work concerns the modeling of radiative transfer in anisotropic turbid media using diffusion theory. A theory for the relationship between microscopic scattering properties (i.e., an arbitrary differential scattering cross-section) and the macroscopic diffusion tensor, in the limit of independent scatterers, is presented. The theory is accompanied by a numerical method capable of performing t

Growth of InAs/InP core-shell nanowires with various pure crystal structures.

We have studied the epitaxial growth of an InP shell on various pure InAs core nanowire crystal structures by metal-organic vapor phase epitaxy. The InP shell is grown on wurtzite (WZ), zinc-blende (ZB), and {111}- and {110}-type faceted ZB twin-plane superlattice (TSL) structures by tuning the InP shell growth parameters and controlling the shell thickness. The growth results, particularly on the

Efficacy and tolerability of proactive treatment with topical corticosteroids and calcineurin inhibitors for atopic eczema: systematic review and meta-analysis of randomized controlled trials

P>Background Long-term low-level topical anti-inflammatory therapy has been suggested as a new paradigm in the treatment of atopic eczema (AE). Objectives To determine the efficacy and tolerability of topical corticosteroids and calcineurin inhibitors for flare prevention in AE. Methods Systematic review of randomized controlled trials reporting efficacy of topical corticosteroids and/or topical c

Polyelectrolyte Mediated Interactions in Colloidal Dispersions: Hierarchical Screening, Simulations, and a New Classical Density Functional Theory

The pair interaction between two charged colloidal particles, in the presence of a polyelectrolyte as well as simple salt, is analyzed theoretically. Of particular interest is the way in which such a combination of salts can be used to induce a strong, long-range attraction, with at most a minor free energy barrier. We show that the nature of the simple salt is highly relevant, i.e., 2:1, 1:1, and

Differential patterns of spontaneous experiential response to a hypnotic induction: A latent profile analysis.

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability

We will be different! Ageism and the temporal construction of old age

Abstract in UndeterminedAgeism has been described as different from other forms of discrimination and paradoxical in the sense that "nonold" people discriminate against their "future selves." The argument of this article is that nonold people may uphold ideas about older people as "the other" by constructing their own future selves as "essentially different" from that of older people of the presen

RapA2 Is a Calcium-binding Lectin Composed of Two Highly Conserved Cadherin-like Domains That Specifically Recognize Rhizobium leguminosarum Acidic Exopolysaccharides

In silico analyses have revealed a conserved protein domain (CHDL) widely present in bacteria that has significant structural similarity to eukaryotic cadherins. A CHDL domain was shown to be present in RapA, a protein that is involved in autoaggregation of Rhizobium cells, biofilm formation, and adhesion to plant roots as shown by us and others. Structural similarity to cadherins suggested calciu

Improvement in time-domain induced polarization data quality with multi-electrode systems by separating current and potential cables

Measuring induced polarization in the time domain with relatively compact multi-channel multi-electrode systems is attractive because of the simplicity of the procedure and thus its efficiency in the field. However the use of this technique is sometimes discouraged by the bad quality of the measurements in cases of high electrode contact resistances that can render data interpretation infeasible o

Connectivity in Reed Warblers Acrocephalus scirpaceus between breeding grounds in Europe and autumn stopover sites in Iberia

We determined the degree of connectivity in the Eurasian Reed Warbler Acrocephalus scirpaceus between breeding regions in central and northern Europe and stopover sites in Iberia, during the autumn migration. We used both recovery data and wing length analyses to achieve this. Biometric data were obtained during 2009 at 11 sampling localities in Iberia, which we amalgamated into four major migrato

Polymorphism of Paracetamol: A New Understanding of Molecular Flexibility through Local Methyl Dynamics.

This study focuses on the interplay of molecular flexibility and hydrogen bonding manifested in the monoclinic (form I) and orthorhombic (form II) polymorphs of paracetamol. By means of incoherent inelastic neutron scattering and density functional theory calculations, the relaxation processes related to the methyl side-group reorientation were analyzed in detail. Our computational study demonstra
