Three-dimensional X-ray diffraction has been used to study the growth kinetics of 1406 individual grains recrystallizing in 50% cold-rolled aluminium. It is found that each grain follows its own kinetics. The radial growth of individual grains is found to often be piecewise linear, and an explanation based on the cell block microstructure of cold-rolled aluminium is proposed. Grain-averaged activa

We evaluated the diagnostic potential of 24S-hydroxycholesterol (24OHC) in cerebrospinal fluid. At a memory clinic, we investigated subjects with subjective cognitive impairment (SCI, n = 33), mild cognitive impairment (MCI) patients (n = 27), MCI patients with later progression into Alzheimer dementia at follow up (n = 10), and patients with AD (n = 24). We also had a control group of healthy vol

When Octavian in 27 BC was given the title of Augustus, a shield was set up in the senate inscribed with four virtues; virtus, clementia, iustitia, and pietas. Aeneas, the great ancestor of Octavian, is frequently praised for pietas, virtus, and iustitia in the Aeneid. Regarding clementia, however, Vergil is conspicuously silent. Indeed, in the battle scenes of books 10 and 12, Aeneas refuses to s

Abstract in UndeterminedA one-dimensional model for the sedimentation-compression-dispersion process in the secondary settling tank can be expressed as a nonlinear strongly degenerate parabolic partial differential equation (PDE), which has coefficients with spatial discontinuities. Reliable numerical methods for simulation produce approximate solutions that converge to the physically relevant sol

Emotion researchers have long use clips from commercial movies to experimentally elicit emotional states. The paper describes how the Niedenthal laboratory selected and tested emotion eliciting movie clips, and presents data on their effectiveness. A summary of published databases of emotion eliciting movies is presented and discussed.

Background: Patients diagnosed with schizophrenia display poor premorbid adjustment (PPA) in half of the cases. Attention deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) are common child psychiatric disorders. These two facts have not previously been linked in the literature. Aims: To determine the prevalence of ADHD/CD problems retrospectively among patients with psychoses, and wh

Malignant gliomas bear the most dismal prognosis of all human cancers despite the progress in therapy of many other tumors. The search for alternative and complementary treatments has therefore a high priority. Emerging knowledge of the dual and diverging role of nitric oxide in glioma biology has focused on possibilities to achieve anti-glioma effects by modulation of nitric oxide (NO) release an

P>The flux of carbon from tree photosynthesis through roots to ectomycorrhizal (ECM) fungi and other soil organisms is assumed to vary with season and with edaphic factors such as nitrogen availability, but these effects have not been quantified directly in the field. To address this deficiency, we conducted high temporal-resolution tracing of 13C from canopy photosynthesis to different groups of

Studies from the public health and epidemiologic fields consider self-assessment of health as a solid measure of general health due to its predictive ability in relation to mortality. Empirical evidence in this direction have justified the generalized use of this measure in health surveys as well as its application to the general population. However, it is important to evaluate whether these findi

Pollination is a key ecosystem service which most often has been studied in isolation although effects of pollination on seed set might depend on, and interact with, other services important for crop production. We tested three competing hypotheses on how insect pollination and pest control might jointly affect seed set: independent, compensatory or synergistic effects. For this, we performed a ca

The aim of this study is to explore whether administration timing affects glycaemic control by lixisenatide once-daily in type 2 diabetes mellitus (T2DM).

Although a substantial proportion of patients with heart failure (HF) have anemia, there is a paucity of data evaluating the impact of anemia on clinical outcome in CRT patients. Our goal was to examine the ability of baseline hemoglobin (Hb) level and change in Hb level over time to predict clinical 2-year outcome and echocardiographic response to CRT.

This study proposes a method for the characterization of respiratory patterns in chronic heart failure (CHF) patients with periodic breathing (PB) and nonperiodic breathing (nPB), using the flow signal. Autoregressive modeling of the envelope of the respiratory flow signal is the starting point for the pattern characterization. Spectral parameters extracted from the discriminant frequency band (DB

Testicular germ cell cancer (TGCC) is the most common malignancy in young men. Genetic variants known to be associated with risk of TGCC only partially account for the observed familial risks. We aimed to identify additional polymorphisms associated with risk as well as histological and clinical features of TGCC in 367 patients and 214 controls. Polymorphisms in ESR2 (rs1256063; OR=0.53, 95% CI: 0

Although identical blood group matching is preferred, it is uncertain if this results in improved survival and, if so, how large the survival benefits are. Earlier studies have yielded conflicting results and are mostly based on single-center cohorts with few long-term results. Recipients with blood group AB are of particular interest regarding nonidentical blood group matching because they may re

Background and objective: Previous studies have reported immunoreactive opioid nerve fibers in the detrusor and lower urinary tract sphincters. However, there is a paucity of in vivo studies demonstrating the direct effect of endogenous opioids in these structures. In the present study, we investigated the contractile actions of intra-arterially administered exogenous Dynorphin-A, Met-enkephalin,

BACKGROUND The association between aging-related testosterone deficiency and late-onset hypogonadism in men remains a controversial concept. We sought evidence-based criteria for identifying late-onset hypogonadism in the general population on the basis of an association between symptoms and a low testosterone level. METHODS We surveyed a random population sample of 3369 men between the ages of 40

Heterodyne light scattering is employed to probe the electrophoretic flow behavior of a concentrated, deionized model colloidal suspension. Both for the fluid and crystalline regime, the power spectra are well described as velocity distributions, which let assume that the power spectra are dominated by the self-dynamic structure factor. Furthermore, all measured power spectra show an increase of t

Initiating prophylactic treatment at an early age is considered to be the optimal form of therapy for a child with haemophilia A or B. The pioneering long term experiences of prophylactic treatment from Sweden and The Netherlands demonstrated the benefit of prophylaxis in retrospective and observational studies. Decades later, these benefits were confirmed in a randomized controlled study in USA.
