Published prospective pediatric exercise intervention studies are short term and use skeletal traits as surrogate endpoints for fractures, whereas other reports infer exercise to be associated with more trauma and fractures. This prospective, controlled exercise intervention study therefore followed both skeletal traits and fracture risk for 36 months. Fractures were registered in children aged 7
PURPOSE: Whether coffee modulates response to endocrine therapy in breast cancer patients is currently unknown. The CYP1A2 and CYP2C8 enzymes contribute to tamoxifen and caffeine metabolism. The purpose was to investigate the impact of coffee consumption on tumor characteristics and risk for early events in relation to breast cancer treatment and CYP1A2 and CYP2C8 genotypes. METHODS: Questionnaire
Browning of inland waters has been noted over large parts of the Northern hemisphere and is a phenomenon with both ecological and societal consequences. The increase in water color is generally ascribed to increasing concentrations of dissolved organic matter of terrestrial origin. However, oftentimes the increase in water color is larger than that of organic matter, implying that changes in the c
We show how to compute the two-loop sunset integrals at finite volume, for non-degenerate masses and non-zero momentum. We present results for all integrals that appear in the Chiral Perturbation Theory (chi PT) calculation of the pseudoscalar meson masses and decay constants at next-to-next-to-leading order, including the case of Partially Quenched chi PT. We also provide numerical implementation
This Letter presents measurements of the polarization of the top quark in top-antitop quark pair events, using 4: 7 fb(-1) of proton-proton collision data recorded with the ATLAS detector at the Large Hadron Collider at root s = 7 TeV. Final states containing one or two isolated leptons ( electrons or muons) and jets are considered. Two measurements of alpha P-l, the product of the leptonic spin-a
The growing interest in the possibility of applying stem-cell therapies to gastroenterological diseases is outlined. Some promising results have been reported, but more research is needed in view of the uncertainties and knowledge gaps that still exist. The ethical issues raised by this kind of research are then indicated and classified. Three problematic kinds of situation are outlined: experimen
Within-category induction is the projection of a generic property from a class (Apples are sweet) to a subtype of that class (Chinese apples are sweet). The modifier effect refers to the discovery reported by Connolly et al., that the subtype statement tends to be judged less likely to be true than the original unmodified sentence. The effect was replicated and shown to be moderated by the typical
When exposed to intermediate glucose concentrations (6-16 mol/l), pancreatic beta-cells in intact islets generate bursts of action potentials (superimposed on depolarised plateaux) separated by repolarised electrically silent intervals. First described more than 40 years ago, these oscillations have continued to intrigue beta-cell electrophysiologists. To date, most studies of beta-cell ion channe
Polythiophenes (PTs), particularly regioregular poly(3-hexylthiophene-2,5-diyl) (rr-P3HT), are important materials in photo-voltaics. The photophysical properties of PTs are still poorly understood, because of their aggregation tendency and formation of interchain species which can be avoided by insulating the conjugated backbone via self-threading. We investigated two polymers, rr-P3HT and its in
Contemporary psychological research has shown that if we are judged by the standards of classical models of rationality our decision-making abilities can be seriously questioned. We are more or less irrational. The article investigates how this 'fact of irrationality' affects the way normative ethical theories should be formulated and the extent to which currently dominant ethical theories can be
Computed tomography angiography (CTA) is today the primary method for the detection of intracranial aneurysms. The technique has evolved considerably during the last decade, and it is important to establish criteria for high image quality, especially with regard to improving the diagnosis of small aneurysms.
Taking a global perspective this paper sets out to theoretically and empirically identify prosperity patterns for four groups of countries at different levels of economic development. It conceptualizes ‘prosperity’ in terms of ecological sustainability, social inclusion, and the quality of life and contextualizes this definition in global perspective. Subsequently, it operationalizes and measures
Next-generation sequencing technologies are making it possible to study the role of rare variants in human disease. Many studies balance statistical power with cost-effectiveness by (a) sampling from phenotypic extremes and (b) utilizing a two-stage design. Two-stage designs include a broad-based discovery phase and selection of a subset of potential causal genes/variants to be further examined in
The study explores the constructs of cognitive restructuring and acceptance using items from well-established measures of the respective constructs in order to determine what subcategories or conceptual nuances that could be empirically detected, and examines these factors’relationship to each other and to positive and negative emotionality, quality of life and clinical status. The design of the s
Vital statistics, published by the National Statistics Institute in Spain, are a highly important source for the study of perinatal health nationwide. However, the process of data collection is not well-known and has implications both for the quality and interpretation of the epidemiological results derived from this source. The aim of this study was to present how the information is collected and
Genetic studies have implicated the neuronal ubiquitin C-terminal hydrolase (UCH) protein UCH-L1 in Parkinson's disease (PD) pathogenesis. Moreover, the function of UCH-L1 may be lost in the brains of PD and Alzheimer's disease patients. We have previously reported that the UCH-L1 polymorphic variant S18Y, potentially protective against PD in population studies, demonstrates specific antioxidant f
Multi-coincidence experiments with detection of both electrons and ions from decay of core-excited and core-ionized states of CO2 confirm that O2 (+) is formed specifically in Auger decay from the C1s-π* and O1s-π* resonances. Molecular rearrangement occurs by bending in the resonant states, and O2 (+) is produced by both single and double Auger decay. It is suggested that electron capture by C(+)
We report on temperature dependence on the drive current as well as long-term effects of annealing in vertical InAs nanowire Field-Effect Transistors. Negatively charged traps in the HfO2 gate dielectric are suggested as one major factor in explaining the effects observed in the transistor characteristics. An energy barrier may be correlated with an un-gated InAs nanowire region covered with HfO2
P>At least one climate model predicts severe reductions of rainfall over Amazonia during this century. Long-term throughfall exclusion (TFE) experiments represent the best available means to investigate the resilience of the Amazon rainforest to such droughts. Results are presented from a 7 yr TFE study at Caxiuana National Forest, eastern Amazonia. We focus on the impacts of the drought on tree m
Introduction: The purpose of this research was to study the influence of cigarette smoking and alcohol consumption on immune response to heptavalent pneumococcal conjugate vaccine, immunoglobulin levels (Ig) and markers of systemic inflammation in patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA). Methods: In total, 505 patients were vaccinated. Six pre-specified groups were enro
