Unraveling Heterogeneities in Mindfulness Profiles: a Review and Latent Profile Analysis of the Five Facet Mindfulness Questionnaire Short‑Form (FFMQ‑SF) in the Spanish Population.

Objectives The Five Facet Mindfulness Questionnaire (FFMQ) is one of the most common self-report instruments used in scientific literature to assess mindfulness. However, mixed evidence has been provided regarding its psychometric properties. Among them, the FFMQ seems to present latent classes or profiles with specific patterns in its facets, which might explain said mixed evidence. This study explores mindfulness profiles in the Spanish population using the short form of the FFMQ (FFMQ-SF) and its relations with relevant constructs (i.e., decentering, self-compassion, psychological well-being, psychopathology, positive and negative states). Methods A general population sample of 826 participants completed instruments measuring mindfulness and related constructs. Latent profile analyses were applied to the FFMQ-SF facets, and profile membership of participants was estimated for relations with related constructs. Results Three latent profiles were found: General Mindfulness, Judgmentally Observing, and Non-judgmentally Aware. General Mindfulness showed expected relations with other constructs, but the other two profiles showed some relations opposite to prior literature: The Judgmentally Observing profile displayed functional behaviors while the Non-judgmentally Aware profile showed an inverse mitigated pattern. Results could not be explained by gender, age, level of studies, or minimum experience with meditation. Conclusions Most people (68%) fall into mindfulness profiles that can be regarded as a continuum (e.g., an overall mindfulness factor). However, the FFMQ-SF shows heterogeneities in its facets due to two unique latent profiles, namely “Judgmentally Observing” (7.4%) and “Non-judgmentally Aware” (24.8%). While the structure of these profiles was replicated, relations with relevant psychological constructs contradicted previous literature. Implications and recommendations for future studies are discussed.post-print1029 K

A Network Analysis of the Five Facets Mindfulness Questionnaire (FFMQ)

Objectives: The Five Facet Mindfulness Questionnaire (FFMQ) is a popular self-report instrument for mindfulness assessment. However, several studies report mixed evidence regarding its reliability and validity. While recent replication studies have shown several issues regarding its latent structure, first-order facets seemed to replicate successfully. This study proposes an exploratory approach to these facets on an item level in one sample, with cross-validation in another sample. Methods: Using a snowball sampling, 1008 participants were recruited in the first sample. Psychometric networks were applied to explore relations between items and item clusters. We compared these exploratory latent variable proposals with previous literature. A second sample of 1210 participants was collected from an FFMQ validation study, and confirmatory factor analyses were applied to cross-validate findings on the first sample. Results: The FFMQ showed a positively correlated network. Exploratory analyses suggested the 5-facet structure as stable with alternatives of 4-facet (merging Observe and Non-Judging) and 6-facet (splitting Acting with Awareness in two) solutions. However, the CFAs in the second sample did not provide clear support to any solution. Conclusions: The FFMQ showed unclear evidence on its latent structure. We propose researchers and users of the FFMQ to use the most fitting solution between the 5 and 6-facet solutions in their data, since the 4-facet solution is difficult to interpret. We also propose cautionary notes and guidelines for researchers and applied users of the FFMQ and regarding this instrument. We conclude that more research is needed in mindfulness assessment to provide robust measurement

Nitrogen Metabolism and Growth Enhancement in Tomato Plants Challenged with Trichoderma harzianum Expressing the Aspergillus nidulans Acetamidase amdS Gene

[EN] Trichoderma is a fungal genus that includes species that are currently being used as biological control agents and/or as biofertilizers. In addition to the direct application of Trichoderma spp. as biocontrol agents in plant protection, recent studies have focused on the beneficial responses exerted on plants, stimulating the growth, activating the defenses, and/or improving nutrient uptake. The amdS gene, encoding an acetamidase of Aspergillus, has been used as a selectable marker for the transformation of filamentous fungi, including Trichoderma spp., but the physiological effects of the introduction of this gene into the genome of these microorganisms still remains unexplored. No evidence of amdS orthologous genes has been detected within the Trichoderma spp. genomes and the amdS heterologous expression in Trichoderma harzianum T34 did not affect the growth of this fungus in media lacking acetamide. However, it did confer the ability for the fungus to use this amide as a nitrogen source. Although a similar antagonistic behavior was observed for T34 and amdS transformants in dual cultures against Rhizoctonia solani, Botrytis cinerea, and Fusarium oxysporum, a significantly higher antifungal activity was detected in amdS transformants against F. oxysporum, compared to that of T34, in membrane assays on media lacking acetamide. In Trichoderma-tomato interaction assays, amdS transformants were able to promote plant growth to a greater extent than the wild-type T34, although compared with this strain the transformants showed similar capability to colonize tomato roots. Gene expression patterns from aerial parts of 3-week-old tomato plants treated with T34 and the amdS transformants have also been investigated using GeneChip Tomato Genome Arrays. The downregulation of defense genes and the upregulation of carbon and nitrogen metabolism genes observed in the microarrays were accompanied by (i) enhanced growth, (ii) increased carbon and nitrogen levels, and (iii) a higher sensitivity to B. cinerea infections in plants treated with amdS transformants as detected in greenhouse assays. These observations suggest that the increased plant development promoted by the amdS transformants was at expense of defensesSIResearch project funding was from the Spanish Ministry of Economy and Competitiveness (Project no.

Nanometer-Scale Lateral p–n Junctions in Graphene/α-RuCl3 Heterostructures

[EN] The ability to create nanometer-scale lateral p-n junctions is essential for the next generation of two-dimensional (2D) devices. Using the charge-transfer heterostructure graphene/alpha-RuCl3, we realize nanoscale lateral p-n junctions in the vicinity of graphene nanobubbles. Our multipronged experimental approach incorporates scanning tunneling microscopy (STM) and spectroscopy (STS) and scattering-type scanning near-field optical microscopy (s-SNOM) to simultaneously probe the electronic and optical responses of nanobubble p-n junctions. Our STM/STS results reveal that p-n junctions with a band offset of 0.6 eV can be achieved with widths of 3 nm, giving rise to electric fields of order 108 V/m. Concurrent s-SNOM measurements validate a point-scatterer formalism for modeling the interaction of surface plasmon polaritons (SPPs) with nanobubbles. Ab initio density functional theory (DFT) calculations corroborate our experimental data and reveal the dependence of charge transfer on layer separation. Our study provides experimental and conceptual foundations for generating p-n nanojunctions in 2D materials.Research at Columbia University was supported as part of the Energy Frontier Research Center on Programmable Quantum Materials funded by the U.S. Department of Energy (DOE), Office of Science, Basic Energy Sciences (BES), under Award No DE-SC0019443.

Somatic signature of brain-specific single nucleotide variations in sporadic alzheimer's disease

© 2014 IOS Press and the authors. All rights reserved. Background: Although genome-wide association studies have shown that genetic factors increase the risk of suffering late-onset, sporadic Alzheimer's disease (SAD), the molecular mechanisms responsible remain largely unknown. Objective: The aim of the study was to investigate the presence of somatic, brain-specific single nucleotide variations (SNV) in the hippocampus of SAD samples. Methods: By using bioinformatic tools, we compared whole exome sequences in paired blood and hippocampal genomic DNAs from 17 SAD patients and from 2 controls and 2 vascular dementia patients. Results: We found a remarkable number of SNVs in SAD brains (~575 per patient) that were not detected in blood. Loci with hippocampus-specific (hs)-SNVs were common to several patients, with 38 genes being present in 6 or more patients out of the 17. While some of these SNVs were in genes previously related to SAD (e.g., CSMD1, LRP2), most hs-SNVs occurred in loci previously unrelated to SAD. The most frequent genes with hs-SNVs were associated with neurotransmission, DNA metabolism, neuronal transport, and muscular function. Interestingly, 19 recurrent hs-SNVs were common to 3 SAD patients. Repetitive loci or hs-SNVs were underrepresented in the hippocampus of control or vascular dementia donors, or in the cerebellum of SAD patients. Conclusion: Our data suggest that adult blood and brain have different DNA genomic variations, and that somatic genetic mosaicism and brain-specific genome reshaping may contribute to SAD pathogenesis and cognitive differences between individuals.BBVA Foundation and MICINN-MINECO.

Working memory of emotional stimuli: electrophysiological characterization

Memorizing emotional stimuli in a preferential way seems to be one of the adaptive strategies brought on by evolution for supporting survival. However, there is a lack of electrophysiological evidence on this bias in working memory. The present study analyzed the influence of emotion on the updating component of working memory. Behavioral and electrophysiological indices were measured from a 3-back task using negative, neutral, and positive faces. Electrophysiological data evidenced an emotional influence on the working memory sensitive P3 component, which presented larger amplitudes for negative matching faces compared to neutral ones. This effect originated in the superior parietal cortex, previously reported to be involved in N-back tasks. Additionally, P3 results showed a correlation with reaction times, where higher amplitudes were associated with faster responses for negative matching faces. These findings indicate that electrophysiological measures seem to be very suitable indices of the emotional influence on working memory

Charmonium spectroscopy and mixing with light quark and open charm states from nF=2 lattice QCD

We study the charmonium spectrum including higher spin and gluonic excitations. We determine an upper limit on the mixing of the eta_c ground state with light pseudoscalar flavour-singlet mesons and investigate the mixing of charmonia near open charm thresholds with pairs of (excited) D and anti-D mesons. For charm and light valence quarks and nF=2 sea quarks, we employ the non-perturbatively improved Sheikholeslami-Wohlert (clover) action. Excited states are accessed using the variational technique, starting from a basis of suitably optimised operators. For some aspects of this study, the use of improved stochastic all-to-all propagators was essential.Comment: 23 pages, v2: references updated, correction of an ambiguous statement, minor typos corrected, some figures update

Delivery outcomes in women with congenital heart disease: results from the Cuban National Programme for pregnancy and heart disease

Abstract Objective To inform on delivery outcomes achieved in congenital heart disease (CHD) patients by the Cuban National Programme for pregnancy and heart disease. Methods Single-centre retrospective study on a prospectively collected cardiac pregnancy database at a tertiary referral hospital (January 2000–May 2017). Primary outcomes: pregnancy duration, outcome, maternal/fetal complications. Results Four hundred sixty-seven pregnancies in 462 recorded cases reached third trimester. Median age: 25 (21–29) years. Patients presented in NYHA class I (97%, n = 453) or II (3%, n = 14), 6% (n = 27) had arrhythmias, 1% (n = 4) had co-morbidities, 1% (n = 4) had impaired left ventricular function. There were 464 singleton pregnancies and 3 twin pregnancies. Of the singleton pregnancies, one resulted in stillbirth (0.2%). The rest were live births (n = 463), median weight 3200 (2900–3421) grams. Median pregnancy duration: 39.1 (38.6–40) weeks. Caesarean rate: 34% (n = 156). All twin pregnancies (n = 3) resulted in live births (n = 6) via caesarean section, of median weight 2710 (2458–2850) grams and median pregnancy duration 37 (36–38) weeks. Maternal cardiovascular complications (< 0.5%, n = 2), and obstetric complications (14%, n = 67) did not result in any mortality. Small-for-gestational-age was the commonest neonatal complication (10%, n = 48), with zero mortality. Three neonates (1%) had CHD. Post-delivery maternal NYHA functional status: class I in 84% (n = 393), class II in 16% (n = 73), and class III in one patient (< 0.5%). Conclusion In middle-income countries management of CHD pregnancies according to existing guidelines can achieve good maternal and fetal outcomes

El álbum poético en portugués y en español: sinergia estética entre palabras e ilustraciones

Este estudo procurou problematizar a relação textual que se observa entre a palavra e a imagem em um tipo de texto especialmente concebido para crianças: o álbum poético. Para tal, utilizamos alguns exemplos textuais significativos desse subgênero literário/editorial ainda em emergência tanto em Portugal quanto na Espanha, e propusemos uma definição e uma caracterização baseadas no comentário de sequências poéticas nas quais a ilustração sustenta o conteúdo verbal. Efetivamente, centrando a atenção no álbum poético de potencial recepção infanto-juvenil, sugere-se uma análise de diversos títulos de autoria portuguesa e espanhola, assente em uma leitura dialógica do texto verbal e do visual. A sinergia que se concretiza entre as duas componentes enunciadas alicerça essa nova construção estética que tem, na verdade e na sua essência, a poesia como matriz e, em larga medida, é devedora dos efeitos expressivos da metáfora.This study aimed to discuss the relation between words and images in a type of text especially directed to children: the picture-poetry book. From significant examples of this literary subgenre still emerging in both Portugal and Spain, we propose a definition and characterization based on the review of poetic sequences in which illustrations support the verbal content. By focusing on picture-poetry books potentially aimed for adolescents and children, we present an analysis of several titles by Portuguese and Spanish authors, based on the dialogic reading between verbal and visual texts. The synergy found between these two components creates de foundantions of a new aesthetic construction which, in truth and in essence, has poetry as its matrix and owes its expressive effects to metaphors.Este estudio ha tenido como objetivo discutir la relación textual que existe entre la palabra y la imagen en un tipo texto especialmente creado para niños: el álbum poético.
