AIM: The aim of this analysis was to examine the average rate and variation of alcohol-related injury across emergency department (ED) studies, the effect of usual drinking on likelihood of alcohol-related injury, whether cross-study variation in rate of alcohol-related injury can be explained by between-study difference in usual consumption and whether social-cultural contextual variables help ex

Electron beam induced current ( EBIC) in a scanning electron microscope ( SEM) was used to identify the positions of heterostructures in InAs/InP nanowires. Composite SEM and EBIC images were used to locate heterostructures and quantum dots in the nanowires, and used in subsequent electron beam lithography to align local gate electrodes to these quantum dots. This has made it possible to use indiv

Coalitions will probably become an increasingly important theme in European Union (EU) politics. The spread of decision making by majority voting promotes coalition-building behaviour. The impending enlargement is predicted to differentiate and polarize policy standpoints within the EU. Increasing levels of policy conflict imply increased propensities for coalition building. Still, the role and na

The issue of factors predisposing for inhibitor development in haemophilia patients is still largely unresolved. In an attempt to address this problem, we initiated a registry in 1996 of siblings with haemophilia and with or without a history of inhibitors. Four hundred and sixty families have accrued, of whom 388 suffer from haemophilia A and 72 haemophilia B. Twenty-five of the brother pairs are

Two ecotypes of a marine intertidal snail (Littorina saxatilis), living at different microhabitats and shore levels, have evolved in sympatry and in parallel across the Galician rocky shore. These ecotypes differ in many traits (including size) due to differential adaptation. They meet, mate assortatively, and partially hybridize at the mid shore where the two microhabitats overlap. The partial se

The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied were 184 representative men, aged 72-76 y

The formation of ectomycorrhizal (ECM) root tissue is characterized by distinct morphological and developmental stages, such as preinfection and adhesion, mantle, and Hartig net formation. The global pattern of gene expression during these stages in the birch (Betula pendula)-Paxillus involutus ECM association was analyzed using cDNA microarrays. In comparison with nonsymbiotic conditions, 251 fun

The methodology for ready-made matrix-assisted laser desorption/ionization (MALDI) target plates covered with an optimized thin layer consisting of matrix and nitrocellulose has been developed. Piezoelectric microdispensing enabled sample depositions in a high-density array format of 2000 sample depositions on a conventionally sized target plate (45 x 47 mm). The sample depositions were made repro

A series of copolymers of N-isopropylacrylamide (NIPAM) and the more hydrophobic comonomer N-tert-butylacrylamide (NTBAM), with increasing NTBAM content (i.e., increasing hydrophobicity) were prepared. The adhesion of human epithelial cells on polymer films prepared from copolymers of NIPAM: NTBAM was observed to increase with increasing polymer hydrophobicity. However, in the absence of serum, ce

Mating behaviour and mating patterns are affected to a large extent by body size in both hermaphrodites and gonochorists. Detailed research on mating patterns, mate choice, pre- and post-copulatory sexual selection in marine pulmonates is wanting, thus warranting more attention as a study system in the future. The simultaneous hermaphroditic limpet Siphonaria capensis (Pulmonata: Basommatophora) s

A microfabricated proteomic sample preparation and sample presentation device, Integrated Selective Enrichment Target, (ISET), comprising an array of 96 perforated nanovials is described. Each perforated nanovial can be filled with solid-phase extraction media for purification and concentration of peptides prior to matrix-assisted laser desorption/ionization mass spectrometry (MALDI IVIS). The val

Several previous studies have addressed pheromone communication in various flour beetles (Coleoptera: Tenebrionidae), including the confused flour beetle, Tribolium confusum (du Val). Different stereoisomers of 4,8-dimethyldecanal (DMD) were reported as the only components of an aggregation pheromone, but the behavioral activity of DMD is low. In the present study, additional previously reported s

We report here on a procedure to obtain large amounts of a chloroplast-localized heat shock protein (HSP21) with unknown structure and function, by using anEscherichia coliexpression system for the pea (Pisum sativum) protein and a purification procedure based on perfusion ion-exchange chromatography. After initial precipitation steps, the sample was applied to cation- and anion-exchange on two co

For a concrete beam resting on a bed of sand, an analytical solution technique is derived by which the mobility can be identified. To achieve realistic predictions, significant damping in the bed needs to be introduced. The modest damping of the concrete has little effect on the mobility for small frequencies whereas it has a significant effect for higher frequencies. An imperfection in the bed in

Background. Children born preterm (PT) have medical conditions and impairments that may affect their oral health. Hypothesis. Our hypothesis for the study was that PT children display more dental behaviour management problems (BMPs) and less favourable oral health behaviour than controls (C). Methods. Parents of 153 PT children and 153 C children were interviewed regarding the children's oral heal
