Twenty-eight-day follow-up of patch test reactions to p-phenylenediamine and p-phenylenediamine dihydrochloride : A multicentre study on behalf of the European Environmental and Contact Dermatitis Research Group

Background: There is an ongoing discussion on whether routinely patch testing with p-phenylenediamine (PPD) 1.0% pet. is safe, owing to the risk of patch test sensitization. Late-appearing patch test reactions may reflect patch test sensitization, but may also be attributable to a low degree of pre-existing sensitization. Objectives: To follow the positive patch test reactions to PPD and its salt

Individual variations in fentanyl pharmacokinetics and pharmacodynamics in preterm infants

Aim: Fentanyl pharmacokinetics and pharmacodynamics are lacking in preterm infants. Our aim was to study these and their relation with a new formulation of fentanyl 5 μg/mL for procedural pain. Methods: Preterm infants were given 0.5 (n = 20, median gestational age 26.5; range 23.3–34.1 weeks) and 2 μg/kg (n = 8, 27.4; 25.3–30.7 weeks) fentanyl, respectively, before skin-breaking procedures or tra

Public entrance accessibility : Psychometric approach to the development of a new assessment instrument

Background: The accessibility of public facilities for all is an issue increasingly gaining focus in policy debates, especially regarding the ageing population. Objective: This paper describes a psychometric approach to the development of a new instrument for assessing the accessibility of public entrances. Methods: Items to include were selected by means of literature review and classified accor

Seasonal and interpopulational phenotypic variation in morphology and sexual signals of Podarcis liolepis lizards

Widespread species often show extensive phenotypic variation due to the contrasting abi-otic and biotic factors that shape selective pressures in different environments. In this context, the gradual and predictable patterns of variation in climatic and environmental conditions found in mountain areas offer a great opportunity to explore intraspecific phenotypic variation. For instance, temperature

Panethnic Differences in Blood Pressure in Europe : A Systematic Review and Meta-Analysis

BACKGROUND: People of Sub Saharan Africa (SSA) and South Asians(SA) ethnic minorities living in Europe have higher risk of stroke than native Europeans(EU). Study objective is to provide an assessment of gender specific absolute differences in office systolic(SBP) and diastolic(DBP) blood pressure(BP) levels between SSA, SA, and EU.METHODS AND FINDINGS: We performed a systematic review and meta-an

Remote ischemic perconditioning attenuates adverse cardiac remodeling and preserves left ventricular function in a rat model of reperfused myocardial infarction

Aims: Remote ischemic conditioning (RIC) is considered a potential clinical approach to reduce myocardial infarct size and ameliorate adverse post-infarct left ventricular (LV) remodeling, however the mechanisms are unknown. The aim was to clarify the impact of RIC on Neuregulin-1 (NRG-1)/ErbBs expression, inflammation and LV hemodynamic function. Methods and results: Male Sprague-Dawley rats were

Swarm materialization through discrete, nonsequential additive fabrication

Biological design is able to achieve remarkable functionality, resilience and adaptability without relying on centralized coordination or resource-intense materials. Agent based construction seeks to emulate these advantages, but the two common approaches - swarm robotics and fully virtual agent simulations - are held back by limitations that are difficult to overcome in isolation. Here we demonst

Inverse engineering of shortcut pulses for high fidelity initialization on qubits closely spaced in frequency

High-fidelity qubit initialization is of significance for efficient error correction in fault tolerant quantum algorithms. Combining two best worlds, speed and robustness, to achieve high-fidelity state preparation and manipulation is challenging in quantum systems, where qubits are closely spaced in frequency. Motivated by the concept of shortcut to adiabaticity, we theoretically propose the shor

Beamline design for plasma-wakefield acceleration experiments at MAX IV

The MAX IV Laboratory is a synchrotron radiation user facility located just outside the city of Lund, Sweden. The facility is made up of two storage rings, at 3 GeV and 1.5 GeV, respectively, and a linear accelerator, serving as a full-energy injector for the rings as well as a driver for the Short-Pulse Facility (SPF) located downstream of the extraction point to the 3 GeV ring. Recently, as part

Effect of post-thermal annealing on the performance and charge photogeneration dynamics of PffBT4T-2OD/PC71BM solar cells

In this work, we studied influence of post thermal annealing on the performance and charge photogeneration processes of PffBT4T-2OD/PC 71 BM solar cells. As-prepared device exhibits a high-power conversion efficiency of 9.5%, much higher than that after thermal annealing. To understand this phenomenon, we studied charge photogeneration processes in these solar cells by means of time resolved spe

Financial assessment of reusing materials in buildings : Comparing financial potential of wood, concrete, and glass reuse

Buildings are responsible for a third of global greenhouse gas emissions, with much of their life cycle impacts resulting from embodied impacts of building materials. One solution to reduce embodied emissions is to use of secondary materials such as by-products and waste materials for producing building materials (in this study referred to as reuse solutions). While this is reported to have positi

Impact of Relay Cooperation on the Performance of Large-Scale Multipair Two-Way Relay Networks

We consider a multipair two-way relay communication network, where pairs of user devices exchange information via a relay system. The communication between users employs time division duplex, with all users transmitting simultaneously to relays in one time slot and relays sending the processed information to all users in the next time slot. The relay system consists of a large number of single ant

Meta-Analysis of Genomewide Association Studies Reveals Genetic Variants for Hip Bone Geometry

Hip geometry is an important predictor of fracture. We performed a meta-analysis of GWAS studies in adults to identify genetic variants that are associated with proximal femur geometry phenotypes. We analyzed four phenotypes: (i) femoral neck length; (ii) neck-shaft angle; (iii) femoral neck width, and (iv) femoral neck section modulus, estimated from DXA scans using algorithms of hip structure a

Above- and belowground insect herbivory modifies the response of a grassland plant community to nitrogen eutrophication

Understanding the role that species interactions play in determining the rate and direction of ecosystem change due to nitrogen (N) eutrophication is important for predicting the consequences of global change. Insects might play a major role in this context. They consume substantial amounts of plant biomass and can alter competitive interactions among plants, indirectly shaping plant community com

Above‐and belowground insect herbivores mediate the impact of nitrogen eutrophication on the soil food web in a grassland ecosystem

Insect herbivores are important drivers of ecosystem processes in grasslands, and can mediate the grassland's response to environmental change. For example, recent evidence shows that above‐ and belowground herbivory, individually and in combination, can modify how a plant community responds to nitrogen (N) eutrophication, an important driver of global change. However, knowledge about how such eff

Anomalous vibrational dynamics in the Mg2Zn11 phase

We present a combined experimental and theoretical study of the structure and the lattice dynamics in the complex metallic alloy Mg2Zn 11, by means of neutron and x-ray scattering, as well as ab initio and empirical potential calculations. Mg2Zn11 can be seen as an intermediate step in structural complexity between the simple Laves-phase MgZn2 on one side, and the complex 1/1 approximants and quas

On the question of commensurability - The Nowotny chimney-ladder structures revisited

A composite approach was used for the structure solution and refinement of two new Nowotny chimney-ladder phases, (Mo/Rh)11Ge18 and (Mo/Rh)13Ge22, found during investigations in the Mo/Rh/Ge system. The descriptions of the phases with conventional models (in I4̄2d (No. 122) with a = 5.885(2) Å, c = 52.62(2) Å for (Mo/Rh)11Ge18 and a = 5.922(1) Å, c = 62.88(4) Å for (Mo/Rh)13Ge22) led to high numbe
