Impact of Adverse Childhood Experiences on Psychotic-Like Symptoms and Stress Reactivity in Daily Life in Nonclinical Young Adults

Background: There is increasing interest in elucidating the association of different childhood adversities with psychosis-spectrum symptoms as well as the mechanistic processes involved. This study used experience sampling methodology to examine (i) associations of a range of childhood adversities with psychosis symptom domains in daily life; (ii) whether associations of abuse and neglect with symptoms are consistent across self-report and interview methods of trauma assessment; and (iii) the role of different adversities in moderating affective, psychotic-like, and paranoid reactivity to situational and social stressors. Method: A total of 206 nonclinical young adults were administered self-report and interview measures to assess childhood abuse, neglect, bullying, losses, and general traumatic events. Participants received personal digital assistants that signaled them randomly eight times daily for one week to complete questionnaires about current experiences, including symptoms, affect, and stress. Results: Self-reported and interview-based abuse and neglect were associated with psychotic-like and paranoid symptoms, whereas only self-reported neglect was associated with negative-like symptoms. Bullying was associated with psychotic-like symptoms. Losses and general traumatic events were not directly associated with any of the symptom domains. All the childhood adversities were associated with stress reactivity in daily life. Interpersonal adversities (abuse, neglect, bullying, and losses) moderated psychotic-like and/or paranoid reactivity to situational and social stressors, whereas general traumatic events moderated psychotic-like reactivity to situational stress. Also, different interpersonal adversities exacerbated psychotic-like and/or paranoid symptoms in response to distinct social stressors. Discussion: The present study provides a unique examination of how childhood adversities impact the expression of spectrum symptoms in the real world and lends support to the notion that stress reactivity is a mechanism implicated in the experience of reality distortion in individuals exposed to childhood trauma. Investigating the interplay between childhood experience and current context is relevant for uncovering potential pathways to the extended psychosis phenotype

A completely-phased diploid genome assembly for ‘Malbec’ cultivar (Vitis vinifera L.)

Poster. Publicado en: BAG Journal of Basic and Applied Genetics, 32 (1 suppl), 2021Most grapevine cultivars originated from the outcrossing of two genetically diverse parents, and are clonally propagated to preserve phenotypes of productive interest. Hence, cultivars are first filial generations (F1) with highly heterozygous diploid genomes, that turn challenging to assemble. ‘Malbec’ is the main cultivar for the Argentine wine industry and it originated in France, from the outcrossing of ‘Magdeleine Noir des Charentes’ and ‘Prunelard’ cultivars. Based on that mother-father-offspring relationship, here we followed the algorithm implemented in the software CanuTrio to produce a phased assembly of ‘Malbec’ genome. For this aim, parental cultivars’ Illumina short-reads were used to sort ‘Malbec’ PacBio long-reads into its haploid complements, to be assembled separately. Postassembly, bioinformatic procedures were employed to reduce the number of duplicated regions and perform sequence error corrections (using ‘Malbec’ Illumina short-reads). We obtained two highly complete and contiguous haploid assemblies for ‘Malbec’, Haplotype-Prunelard (482.4 Mb size; contig N50=7.7 Mb) and Haplotype-Magdeleine (479.4 Mb size; contig N50=6.6 Mb), with 96.1 and 95.8% of BUSCO genes, respectively. We tested for the composition of both haplophases with the tool Merqury, and observed 15% of both assemblies affected by structural variations, along with 3.2 million SNPs and 0.6 million InDels. Our results indicate that this is a valid approach to assemble highly heterozygous and complex diploid genomes in a completely-phased way.EEA MendozaFil: Calderón, Luciano.

Whole genome resequencing and custom genotyping unveil clonal lineages in ‘Malbec’ grapevines (Vitis vinifera L.)

Grapevine cultivars are clonally propagated to preserve their varietal attributes. However, genetic variations accumulate due to the occurrence of somatic mutations. This process is anthropically influenced through plant transportation, clonal propagation and selection. Malbec is a cultivar that is well-appreciated for the elaboration of red wine. It originated in Southwestern France and was introduced in Argentina during the 1850s. In order to study the clonal genetic diversity of Malbec grapevines, we generated whole-genome resequencing data for four accessions with different clonal propagation records. A stringent variant calling procedure was established to identify reliable polymorphisms among the analyzed accessions. The latter procedure retrieved 941 single nucleotide variants (SNVs). A reduced set of the detected SNVs was corroborated through Sanger sequencing, and employed to custom-design a genotyping experiment. We successfully genotyped 214 Malbec accessions using 41 SNVs, and identified 14 genotypes that clustered in two genetically divergent clonal lineages. These lineages were associated with the time span of clonal propagation of the analyzed accessions in Argentina and Europe. Our results show the usefulness of this approach for the study of the scarce intra-cultivar genetic diversity in grapevines. We also provide evidence on how human actions might have driven the accumulation of different somatic mutations, ultimately shaping the Malbec genetic diversity pattern.EEA MendozaFil: Calderón, Luciano.

Tuning the Photonic Behavior of Symmetrical bis-BODIPY Architectures: The Key Role of the Spacer Moiety

Herein we describe the synthesis, computationally assisted spectroscopy, and lasing properties of a new library of symmetric bridged bis-BODIPYs that differ in the nature of the spacer. Access to a series of BODIPY dimers is straightforward through synthetic modifications of the pending ortho-hydroxymethyl group of readily available C-8 (meso) ortho-hydroxymethyl phenyl BODIPYs. In this way, we have carried out the first systematic study of the photonic behavior of symmetric bridged bis-BODIPYs, which is effectively modulated by the length and/or stereoelectronic properties of the spacer unit. The designed bis-BODIPYs display bright fluorescence and laser emission in non-polar media. The fluorescence response is governed by the induction of a non-emissive intramolecular charge transfer (ICT) process, which is significantly enhanced in polar media. The effectiveness of the fluorescence quenching and also the prevailing charge transfer mechanism (from the spacer itself or between the BODIPY units) rely directly on the electron-releasing ability of the spacer. Moreover, the linker moiety can also promote intramolecular excitonic interactions, leading to excimer-like emission characterized by new spectral bands and the lengthening of lifetimes. The substantial influence of the bridging moiety on the emission behavior of these BODIPY dyads and their solvent-sensitivity highlight the intricate molecular dynamics upon excitation in multichromophoric systems. In this regard, the present work represents a breakthrough in the complex relationship between the molecular structure of the chromophores and their photophysical signatures, thus providing key guidelines for rationalizing the design of tailored bis-BODIPYs with potential advanced applications.We gratefully acknowledge the Spanish Ministerio de Economia y Competitividad (MINECO) (MAT2017-83856-C3-1-P and 3-P; CTQ2015-66702-R), Ministerio de Economía y Competitividad (MINECO), and Fondo Europeo de Desarrollo Regional (FEDER) (CTQ2015-66702-R, MINECO/FEDER, UE), Ministerio de Ciencia, Innovación y Universidades (MCIU), Agencia Estatal de Investigación (AEI), Fondo Europeo de Desarrollo Regional (FEDER) (RTI2018-094862-B-I00, MCIU/AEI/FEDER, UE), and Gobierno Vasco (project IT912- 16) for financial support.
