Several studies have demonstrated the involvement of soil-borne Phytophthora species, especially Phytophthora quercina , in European oak decline. However, knowledge about the pathogenicity of P. quercina in natural forest soils is limited. The short-term effects of two south-Swedish isolates of P. quercina on root vitality of Quercus robur seedlings grown in two different soils, one high pH, nutri

BACKGROUND: This study was undertaken to evaluate some possible risk factors for hypospadias with special regard to parity, subfertility and maternal smoking. METHODS: With the use of the Swedish health registries, 3,262 infants with a diagnosis of hypospadias were identified among 1,413,811 infants born in 1983-96 with prospectively collected smoking exposure during pregnancy. Odds ratios (OR) an

The high resolution infrared gas phase spectrum of isoxazole in the range 600-1400 cm(-1) has been recorded and more precise centres obtained for a number of bands; analyses of the nu(7)(A') band at 1370.9 cm(-1) and the nu(16)(A") band at 764.9 cm(-1) have been performed. Use of the Watson Hamiltonian, A-reduction, IIIr-representation and simultaneous analysis of the present IR and previous micro

Plasma cell differentiation is induced in vitro by lipopolysaccharide (LPS) stimulation but can be blocked by including anti-CD40 antibodies. Using subtractive cDNA hybridization we have identified the cell surface protein Ly6C as differentially expressed on B cells stimulated with LPS only. Ly6C has been shown to be expressed on certain T cell subsets and on subsets of macrophages and NK cells, b

Objective: The aim of this study was to construct a rating scale to predict long-term outcome on the basis of clinical and sociodemographic characteristics in patients with symptoms of psychosis who seek psychiatric help for the first time. Method: Patients (N = 153) experiencing their first episode of psychosis (DSM-IV schizophrenia, schizophreniform disorder, schizoaffective disorder, brief psyc

The early marsh orchid, Dactylorhiza incarnata (L.) Soo s. l., grows in medium-rich to rich fens and marshes over much of Europe and parts of Asia. The species is highly polymorphic and different forms may grow together at the same site. In the present study, I tested the hypothesis that these forms represent different migrant populations that have colonized Scandinavia independently of each other

Ferrochelatase is the terminal enzyme in haem biosynthesis, i.e. the enzyme that inserts a ferrous ion into the porphyrin ring. Suggested reaction mechanisms for this enzyme involve a distortion of the porphyrin ring when it is bound to the enzyme. We have examined the energetics of such distortions using various theoretical calculations. With the density functional B3LYP method we calculate how m

We propose a new method to reconstruct the electric field of attosecond pulse trains. The phase of the high-order harmonic emission electric field is Taylor expanded around the maximum of the laser pulse envelope in the time domain and around the central harmonic in the frequency domain. Experimental measurements allow us to determine the coefficients of this expansion and to characterize the radi

The paper compares two lexical items, Icelandic ma@?ur and Swedish man, for the construction of a detached, general discourse stance (Berman, Ragnarsdottir and Stromqvist, 2002). Both forms mean 'man', but they can also be used in a generic sense. In that usage, Icelandic ma@?ur is associated with several semantic, pragmatic, and stylistic constraints, whereas Swedish man is more freely applicable

The European Study on Adult Well-being (ESAW), funded by the European Union, was conducted during 2002 and 2003 in Austria, Italy, Luxembourg, The Netherlands, United Kingdom and Sweden. The aim of the interdisciplinary study was the conceptual clarification and the identification of factors contributing to life satisfaction for older people. Five key components were included in the study: (1) phy

Background-The time course and magnitude of infarct involution, functional recovery, and normalization of infarct-related electrocardiographic (ECG) changes after acute myocardial infarction (MI) are not completely known in humans. We sought to explore these processes early after MI and during infarct-healing using cardiac MRI. Methods and Results-Twenty-two patients with reperfused first-time MI

Animals foraging in a heterogeneous environment may combine prior information on patch qualities and patch sample information to maximize intake rate. Prior information dictates the long-term expectations, whereas prior information in combination with patch sample information determines when to leave an individual food patch. We examined patch use behaviour of benthic feeding fish in their natural

A comparative study of light pf shell nuclei using cranked Nilsson-Strutinsky model and the spherical shell model indicates that some of the signature splitting between the partner bands in odd-A nuclei originates from a gradual decrease in the contents of the pairing energy as spin increases.

The 'buck-passing' account equates the value of an object with the existence of reasons to favour it. As we argued in an earlier paper, this analysis faces the 'wrong kind of reasons' problem: there may be reasons for pro-attitudes towards worthless objects, in particular if it is the pro-attitudes, rather than their objects, that are valuable. Jonas Olson has recently suggested how to resolve thi

In the presence of high concentrations of inert macromolecules, the self-association of proteins is strongly enhanced through an entropic, excluded-volume effect variously called macromolecular crowding or depletion attraction. Despite the predicted large magnitude of this universal effect and its far-reaching biological implications, few experimental studies of macromolecular crowding have been r

A refined formulation of an existing polymer density functional theory is presented, wherein an intrachain stiffness is introduced via a bending potential. Comparisons with Metropolis Monte Carlo simulations in a slit geometry shows that this leads to a considerable improvement of the predicted density profile for a hard sphere polymer melt, at low density. We also show how the corresponding surfa

Surveys of prescribing patterns in both hospitals and primary care have usually shown delays in translating the evidence from clinical trials of pharmacological agents into clinical practice, thereby denying patients with heart failure (HF) the benefits of drug treatments proven to improve well-being and prolong life. This may be due to unfamiliarity with the evidence-base for these therapies, the

Concentrations of interleukin 6 (IL-6) and its receptor are increased in human prostate cancer. Prostate cancer LNCaP-IL-6+ cells, established after prolonged treatment with IL-6, have been found to acquire a growth advantage. Vascular endothelial growth factor (VEGF) may accelerate the growth of various tumours by stimulation of VEGF receptor 2 (VEGFR-2). To understand better the regulation of pr
