Raptors are good sentinels of environmental contamination and there is good capability for raptor biomonitoring in Europe. Raptor biomonitoring can benefit from natural history museums (NHMs), environmental specimen banks (ESBs) and other collections (e.g. specialist raptor specimen collections). Europe's NHMs, ESBs and other collections hold large numbers of raptor specimens and samples, covering long periods of time. These collections are potentially a valuable resource for contaminant studies over time and space...

Information Technology (IT) continues to evolve and develop with electronic devices and systems becoming integral to healthcare in every country. This has led to an urgent need for all professions working in healthcare to be knowledgeable and skilled in informatics. The Technology Informatics Guiding Education Reform (TIGER) Initiative was established in 2006 in the United States to develop key areas of informatics in nursing. One of these was to integrate informatics competencies into nursing curricula and life-long learning...

In this study, a new analytical procedure based on isotachophoresis (ITP) coupled to a multi collector inductively coupled plasma mass spectrometer named Stop-Flow-ITP-MC-ICPMS is developed for exhaustive and high-precision multi-elemental isotopic characterization. We demonstrate that Stop-Flow-ITP makes it possible to stop the analytes migration several times for a duration compatible with the detector configuration changes without losing the separation performance. With this procedure, isotope ratio measurements of four lanthanides of interest for nuclear applications (Nd, Sm, Eu and Gd) were obtained with a reproducibility better than 0...

The computational identification of selenoprotein genes is complicated by the dual meaning of the UGA codon as stop and selenocysteine. SECIS elements are RNA structures essential for selenocysteine incorporation, which have been used as markers for selenoprotein genes in many bioinformatics studies. The most widely used tool for eukaryotic SECIS finding has been recently improved to its third generation, SECISearch3. This program is also a component of Seblastian, a pipeline for the identification of selenoprotein genes that employs SECIS finding as the first step...

In this paper, Bio-MOF-1 is prepared as reported and then Eu(3+) is introduced into it via cation exchange method. A FAM-labeled ssDNA is chosen to fabricate with the obtained Eu(3+)@Bio-MOF-1. A luminescent hybrid material is assembled, which can exhibit the fluorescence of Eu(3+) and FAM simultaneously by adjusting the ratio of FAM-ssDNA and Eu(3+)@Bio-MOF-1. The sample is then used for the detecting of metal ions, results shows which has good selectively for Cu(2+) (LOD = 0.14 μM, 0-250 μM). The introduction of Cu(2+) can quench the fluorescence of FAM while the luminescent intensity of Eu(3+) enhancing...

Infections in poultry are an economic and health problem in Europe and worldwide. The most common infections are associated with salmonellosis, colibacillosis, campylobacteriosis, and others. The prevalence of Campylobacter-positive poultry flocks in European countries varies from 18% to 90%. In the United States, the prevalence of infected flocks is nearly 90%. A similar percentage of infection has been noted for salmonellosis (about 75-90%) and E. coli (90-95%). The occurence of Clostridium perfringens is a major problem for the poultry industry, with some estimates suggesting colonization of as many as 95% of chickens, resulting in clinical or subclinical infections...

Health Care Workers (HCWs) are a high-risk group for contracting Vaccine-Preventable Diseases who, despite legislation and guidance, remain undervaccinated. In order to understand their barriers and needs, focus groups were formed with 278 physicians, nurses, infection-control personnel, and policy-makers in 7 EU MS. Several implications for the development of promotional initiatives were identified including the need to overcome organizational barriers, to sensitize HCWs about the importance of immunization and to provide specific up-to-date information about vaccinations covering prevalence of diseases, protection years, side effects, administration times, antibody examinations, costs and immunization settings...

Microrods of [Tb2(bpydc)3(H2O)3]·nDMF (TbMOF) were employed as a platform for grafting a β-diketonate complex of Eu(3+) for the purpose of obtaining ratiometric luminescence thermometer materials. A straightforward post-synthetic functionalization is employed to obtain the TbMOF@Eu_tfac (tfac = trifluoroacetylacetonate) compounds. The emission color of the TbMOF@Eu compounds can be slightly tuned by varying the percentage of the grafted β-diketonate complex of Eu(3+). Also, as shown, the thermometric properties of the material can be tuned by the percentage of grafted β-diketonate complex of Eu(3+)...

The organic compound of coumarin-3-carboxylic acid (CCA), deprotonated beforehand by NaOH, and the 1-octane sulfonic acid anion (OS) were co-intercalated into the gallery of the layered europium hydroxide (LEuH) via an ion exchange method. Different molar ratios of CCA/OS and NaOH/CCA gave rise to the composites of CCA1-xOSx-LEuH (x = 0.8-1.0) showing different emission intensities. In formamide (FM), all composites were delaminated and the formed colloidal suspensions exhibited enhanced red luminescence of Eu(3+) in comparison with the OS-LEuH without CCA...

Informatics increases the yield from neuroscience due to improved data. Data sharing and accessibility enable joint efforts between different research groups, as well as replication studies, pivotal for progress in the field. Research data archiving solutions are evolving rapidly to address these necessities, however, distributed data integration is still difficult because of the need of explicit agreements for disparate data models. To address these problems, ontologies are widely used in biomedical research to obtain common vocabularies and logical descriptions, but its application may suffer from scalability issues, domain bias, and loss of low-level data access...

We report the synthesis of spherical-shaped rare-earth (Eu(3+) and Tb(3+)) ions doped CaMoO4 nanoparticles in double solvents (IPA and H2O) with the help of autoclave. The X-ray diffraction patterns well match with the standard values and confirm the crystallization in a tetragonal phase with an I41/a (88) space group. The luminescence spectra exhibit the strong red and green emissions from Eu(3+) and Tb(3+) ions doped samples, respectively. The X-ray photoelectron spectroscopy results show the oxidation states of all the elements present in the sample...

In the European Union (EU), the regulatory framework regarding diagnostic allergen extracts is currently in the process of being implemented at the national level. Due to these regulations, the initial and periodic renewal expenses for the registration of diagnostic allergen extracts may render extract production unprofitable. Consequently, many extracts may be at risk of removal from the market. The current survey, which was conducted by a task force of the European Academy of Allergy and Clinical Immunology, aimed to assess the current practice of allergy diagnosis in Europe...

REVIEW
Heide Muckenfuß
The number of falsified medicines on the German market has distinctly increased over the past few years. In particular, stolen pharmaceutical products, a form of falsified medicines, have increasingly been introduced into the legal supply chain via parallel trading. The reasons why parallel trading serves as a gateway for falsified medicines are most likely the complex supply chains and routes of transport. It is hardly possible for national authorities to trace the history of a medicinal product that was bought and sold by several intermediaries in different EU member states...

The electronic, magnetic and optical properties of lanthanide substitutional doping (∼2% concentration) on the MoS2 monolayer have been investigated within the density functional theory formalism together with the Hubbard correction (DFT+U). The dopants investigated include Ce, Eu, Gd, Lu and Tm. The calculated dopant substitutional energies under both Mo-rich and S-rich conditions suggest that it is possible to experimentally realize the lanthanide doped MoS2 monolayer systems. The Eu, Gd and Tm dopants induce strong magnetization in the host lattice...

Aflatoxins and zearalenone (ZEN) are highly common mycotoxins in maize and maize-based products. This study aimed to report a time-resolved fluorescence immunochromatographic assay (TRFICA) developed using two idiotypic nanobodies for rapid, quantitative, and simultaneous detection of aflatoxin B1 (AFB1) and ZEN in maize and its products. A novel Eu/Tb(III) nanosphere with enhanced fluorescence was prepared as a label and conjugated to anti-idiotypic nanobody (AIdnb) and monoclonal antibody (mAb). On the basis of nanosphere-antibody conjugation, two patterns of competitive time-resolved strip methods (AIdnb-TRFICA and mAb-TRFICA) were established and compared...

Hailing Sun, Xiao Wu, Dengfeng Peng, K W Kwok
Ferroelectric oxides with luminescent ions hold great promise in future optoelectronic devices because of their unique photoluminescence and inherent ferroelectric properties. Intriguingly, the photoluminescence performance of ferroelectric ceramics could be modulated by an external electric field. However, researchers face a current challenge of the diminutive extent and degree of reversibility of the field-driven modification that hinder their use in room temperature practical applications. Within the scope of current contribution in rare-earth doped bismuth sodium titanate relaxors, the most important information to be noted is the shifting of the depolarization temperature towards room temperature and the resulting considerable enhancement in ergodicity, as evidenced by the dielectric properties, polarization and strain hysteresis, as well as the in-situ Raman/ X-ray diffraction studies...

Oral ulipristal acetate (Esmya(®); Fibristal(®)), a synthetic selective progesterone receptor modulator, is the first selective progesterone modulator to be approved for the treatment of uterine fibroids. It was initially approved for the preoperative treatment of moderate to severe uterine fibroid symptoms in women of reproductive age. Recently, the indication was extended in the EU to include the intermittent treatment of moderate to severe uterine fibroid symptoms. This narrative review summarizes pharmacological, efficacy and tolerability data relevant to the preoperative and intermittent use of ulipristal acetate in patients with symptomatic uterine fibroids...
