Abstract: With contributions from the global natural product (NP) research community, and continuing the Raw Data Initiative, this review collects a comprehensive demonstration of the immense scientific value of disseminating raw nuclear magnetic resonance (NMR) data, independently of, and in parallel with, classical publishing outlets.

Abstract: WITH THE INCREASE IN prevalence of food allergy (FA) in young children, early childhood education and care (ECEC) providers are likely to have more enrolments of children who are at risk of anaphylaxis. This study examines the status of FA management in ECEC, and assesses the services’ current readiness to prevent and manage FA. A cross-sectional study comprising an online survey with multiple-choice and open-ended questions was conducted with 53 long day care services in Western Australia. Among the respondents, 83 per cent of services had at least one child enrolled with FA, 96 per cent had an FA policy, and 91 per cent required staff to undertake anaphylaxis training. A high level of self-reported confidence and skills were demonstrated however, gaps were identified in risk-minimisation knowledge, use of adrenaline (epinephrine) autoinjectors and available resources. Extensive promotion of available resources will help improve compliance with anaphylaxis guidelines.

Abstract: Introducción: el ruido ha sido reconocido como un contaminante ambiental asociado al incremento de la frecuencia cardiaca, la presión arterial y los niveles de cortisol. Objetivo: establecer, mediante una revisión crítica de la literatura, la relación entre la exposición al ruido y la variabilidad de la frecuencia cardiaca, la presión arterial y los niveles de cortisol en personas expuestas al ruido de forma prolongada. Métodos: se realizó una búsqueda sistemática de la literatura en SCOPUS, PubMed y LILACS, en la cual se usaron términos MeSh y DeCS. La búsqueda arrojó un total de 253 artículos, de los cuales 50 fueron seleccionados para esta revisión. Resultados: la exposición al ruido genera un aumento en la frecuencia cardiaca, lo cual representa un riesgo de sufrir eventos cardiovasculares. Existe una relación positiva entre la presión arterial y la exposición al ruido. El ruido induce la liberación de hormonas como las catecolaminas y corticoesteroides, los cuales afectan el sistema simpático y parasimpático. Conclusión: la evidencia indica que existe una relación indirecta y positiva entre una exposición significativa y prolongada al ruido como evento estresor y la variabilidad de la frecuencia cardiaca, el aumento de la presión arterial y los niveles de cortisol.

Abstract: A set of guiding principles for the development of a standard for FAIR management of spectroscopic data are outlined and discussed. The principles form the basis for future recommendations of IUPAC Project 2019-031-1-024 specifying a detailed data model and metadata schema for describing the contents of an “IUPAC FAIRData Collection” and the organization of digital objects within that collection. Foremost among the recommendations will be a specification for an “IUPAC FAIRData Finding Aid” that describes the collection in such a way as to optimize the findability , accessibility , interoperability , and reusability of its contents. Results of an analysis of data provided by an American Chemical Society Publications pilot study are discussed in relation to potential workflows that might be used in implementing the “IUPAC FAIRSpec” standard based on these principles.

Abstract: The contribution of the solvation energies to the assembly of polynuclear helicates reduces the free energy of intermetallic repulsion, DeltaE(MM), in condensed phase to such an extent that stable D(3)-symmetrical tetranuclear lanthanide-containing triple-stranded helicates [Ln(4)(L4)(3)](12+) are quantitatively produced at millimolar concentrations, despite the twelve positive charge borne by these complexes. A detailed modelling of the formation constants using statistical factors, adapted to self-assembly processes involving intra- and intermolecular connections, provides a set of five microscopic parameters, which can be successfully used for rationalizing the stepwise generation of linear bi-, tri- and tetranuclear analogues. Photophysical studies of [Eu(4)(L4)(3)](12+) confirm the existence of two different binding sites producing differentiated metal-centred emission at low temperature, which transforms into single site luminescence at room temperature because of intramolecular energy funelling processes.

Abstract: The connection of lipophilic gallic acid derivatives at the 5,5'- or 6,6'-positions of the rigid 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine core provides two pro-mesogenic tridentate ligands L10 and L12, whose molecular shapes, anisometries, and directional intermolecular pi-stacking can be tuned. X-ray diffraction data in the crystalline state, combined with solution 1H NMR measurements, show that complexation with trivalent lanthanides, Ln(III), produces the neutral hemi-disklike complexes [Ln(Li)(NO3)3] (i = 10, 12), which dimerize to give the rodlike bimetallic complexes [Ln2(Li)2(NO3)6] at lower temperature. The relevant thermodynamic parameters for the latter process depend on the nature of the ligand, the size of the metal ion, and the strength of the intermolecular interactions involved in the condensed phase. These three-dimensional models obtained for the complexes in the crystals and in solution are eventually confronted with small-angle XRD profiles recorded in the intermediate thermotropic liquid crystalline phase, in which the rigidity of the packed polyaromatic cores is maintained, while the alkyl chains are molten. According to the specific geometries and nuclearities of the molecular complexes, three types of mesophases (lamellar, columnar, and cubic) can be induced, which provides a direct correlation between the microscopic arrangements and the macroscopic ordering in lanthanide-containing metallomesogens.
